How can I recover my Samsung Memos?

My phone was erased, but I already backed up my entire Google account and Samsung Cloud, but it looks like Samsung apps have not been restored. My SHealth data disappeared, as did most of the photos and videos from Samsung Gallery (although they were all restored in my Google Photos). My main problem now is that all my notes are gone and I don’t know how to get them back. It says in the settings that the notes are synced, but I don’t know how to restore them. I tried to download the Samsung Notes app to try to restore the notes to it, but it didn’t work. I also tried deleting and re-adding my Samsung account, but it gave nothing.

Any help would be greatly appreciated as I have scraps from over two years ago.

It can also be useful if there is a way to restore old backups.

I’m so desperate that I even tried to root my phone (any advice on retrieving my notes in this way will also be taken into account). Thank you

What do we need

Instruction. How to uninstall, reinstall, change the Android operating system.

Our users have a lot of questions about the possibility of uninstalling, reinstalling and replacing the Android operating system. We decided to answer them briefly and exhaustively in our article.

And so what is the difference between a mobile operating system compared to desktop Windows or Linux:

  • The fact that you will not find drivers for them simply does not exist, and Android by the manufacturer or enthusiasts is customized individually for each device.
  • There is no full-fledged alternative to Android in the form of another OS. it’s almost impossible to install iOS or Windows Phone on your own. And it is necessary?
  • Reinstalling in the case of mobile devices means reflashing. We read how to make?
  • If necessary, most problems can be solved in an easier way by returning to factory settings or Hard reset.
  • OS updates are often released by the manufacturer himself, and if there is no official update, then look for custom firmware from a craftsman or a group of users with your model. What are the benefits of custom firmware?
  • A friend of mine who likes to experiment more than once turned his smartphone into a brick if the firmware was not successful and always successfully revived it!
  • The graphical shell from the manufacturer is always easy to disable or replace with any other.
  • Android without Root is practically not killed. In case of problems, everything is solved by Hard Reset.
  • Preinstalled programs cannot be removed without ROOT. Without it, you are still limited in many ways, but this is done for the safety and reliability of the OS. Read more about Root.
  • Inappropriate actions with Root will become a huge source of problems in the operation of your device. And now nothing will hold back viruses in the OS. ROOT rights will void the warranty.
  • After installing custom firmware, you may face the fact that something will not work or will not work correctly in your smartphone. In this case, you can always roll back using CWM, which makes a backup copy of the firmware of your device with all the programs and settings you have installed. And if you are satisfied with the firmware, then the Titanium Backup application will help you restore all your installed programs and data.
  • To completely remove the Android OS installed on your smartphone or tablet, you need to use special applications for this purpose, for example, ACMEUninstaller, which carries out a complete physical removal of all operating system data, freeing up space on flash memory or disk. Then you need to clean out the remaining directories from garbage using the command line or the webOS interface.
  • And the last option, which will further expand your possibilities, is installation using an application called ROM Manager “Custom Recovery” or a pre-boot system that allows you to work with the device before loading the Android OS. Analogue of Ms Dos for the mobile platform. Custom Recovery allows you to: remove or install Android and other operating systems firmware, backup and restore data, install custom linux kernels and system patches, format and create partitions on a micro SD card.
  • Before flashing, think carefully: you need it. a new firmware can bring anxiety and harm more than good.

Important! When updating the firmware, settings often fly off and data is deleted, so make a preliminary backup. Software for backup and synchronization of Android with computer.

Self-flashing and updating

There are two ways to update the firmware of a smartphone or tablet: manual and automatic. But the likelihood of failure, albeit low, cannot be ruled out.

Features of OS reinstallation

The Android operating system is the most widespread and functional software for mobile devices. In addition, it has an open source code, which allows even amateurs to change and adjust the “axis” for themselves.

But despite all its merits, it is prone to glitches and errors. Therefore, the need to reinstall Android is a matter of time.

And if everything is clear with Windows and there are no special problems with reinstallation, then the mobile OS is not so easy to reflash. If reinstalling the OS on Android is wrong, you can ruin your phone.

If you decide to reinstall Android on your phone yourself, then you first need to familiarize yourself with a number of nuances and possible problems.

The process of reinstalling Android on a smartphone or tablet may vary depending on the manufacturer and model, as well as the firmware.

Reinstalling Android on a smartphone in automatic mode

Manufacturers of most smartphones of well-known brands inform users about the need to reflash. In practice, information appears in the notification curtain that updates are available. After clicking on the message, the owner of the smartphone can reinstall Android right at this moment or postpone the process for a while and activate the option on his own.

The Android operating system is regularly updated, plus some manufacturers use their own skins that are placed on top of the OS. Due to this, it is impossible to provide an exact algorithm for how to enable automatic Android updates. The steps below may differ depending on the OS version and shell type (EMUI, Flyme, MIUI, etc.).

To enable automatic updates, you need:

  • Go to device settings.
  • Select the section “Software update”.
  • Check the box next to “Auto-update”.

After that, Android will be reinstalled automatically. The user only needs to not cancel the operation when the next notification pops up. And the process itself will take 5-15 minutes.

2 way

  • Download the update file to your smartphone or tablet.
  • Disable device.
  • Enter the engineering menu (depending on the manufacturer, this can be one of the combinations of the power and volume buttons).
  • In the menu that opens, select “System Upgrade”.
  • If desired, clear the data by clicking on “Clear Data”.
  • Press “Start” and wait for the end of the process.

Each of the presented methods is good in its own way. Still, it is recommended to start with the first one. Only on condition that during the Android update it was not possible to use the standard interface of the gadget, you must proceed to open the system menu.

How To install, Update and Flash Any Samsung Mobile software

If none of the proposed reinstallation options helped to implement the idea of ​​updating the smartphone’s firmware, the only way to solve the problem is to contact a service provider. Under the guarantee, such an operation can be performed at one of the addresses indicated in the coupon attached to the device. Otherwise, you should contact any official service, where employees will reinstall for an additional fee.

How to reinstall Android system on phone

You can reinstall the system on Android by following certain simple steps. In addition, the huge advantage of the Android OS is its open source code, thanks to which you can easily not only reinstall the software on an identical one, but also try various amateur assemblies with special innovations and additions.

System reinstallation process

Before reinstalling Android on your device, copy all important data from main memory to your flash device or PC. Any phone or tablet also has a special function. data backup. With its help, you can put your custom settings on external media or in the cloud to virtually completely restore personal information on the device. It is recommended to do it every time you change the firmware, update the device or install new drivers. Reinstallation of the Android operating system can be carried out using several methods (relevant both on the phone and on the tablet):

  • Reinstallation via a computer using a USB cable;
  • Using the “Recovery Menu” directly on your Android phone.

Both options are suitable for both official builds and custom firmware versions. Select the reinstall package you need and follow the algorithm below.

Tips and Cautions

You may notice that updating or installing other firmware on gadgets running Android is not difficult. However, you need to understand that performing the described actions, smartphones may become unusable if there are certain errors. You must be very careful when choosing the firmware itself, since the wrong software can make it so that the phone will be impossible to restore even to the master in the service.

It is recommended to use variants only from official sources. Of course, such firmware will not differ in original design and beauty, and the possibilities are often ordinary, without additions, but the result will be 100% successful.

Firmwares from third-party developers are characterized by a beautiful design, the presence of additional features, but it is impossible to speak about quality with confidence. It should always be remembered that before installing a new firmware, it is recommended to use easier methods to solve problems.

Check the number from where you called

This question is asked by many users of smartphones and tablets based on Andro.

Not so simple. Rather, everything is even easier than it seems. Let’s say that the smartphone starts to slow down, freezes, and no actions help to return it to its previous speed. What will the user want to do? Rather, everything, reinstall the operating system. Android has a special feature that allows you to do a full factory reset, thereby restoring the device to the factory factory state. This function is good because you do not need to download the firmware and install it. you just need to press a few touch keys, after which the smartphone or tablet will “reset”, returning to its original state. Conveniently? Not that word.

Of course, if you have a strong desire, you can download the same firmware that is installed on your gadget and install it on your device. However, we do not see any sense in this. this is just a waste of time, and often. and nerves. Therefore, now we will tell you how to reset the settings. To do this, we will use a Samsung Galaxy smartphone.

Please note that when you reset the settings, all information from the device is deleted, you need to take care of the backup of the necessary data in advance in order to avoid their irrevocable deletion.

Find the settings icon on the desktop and tap on it.

The next item is a search in the menu for the “Archiving and Reset” section (it can also be called “Restore and Reset”).

Go to this section, at the bottom of the screen you will see the item “Reset data” or “Reset settings”. Click on it.

Here you will see information about what will be deleted from your smartphone or tablet. In addition, if you are logged into certain accounts, this will also be indicated. Click on the “Reset Device” button.

Now, once again confirm the deletion of data by clicking on the “Delete all” button.

The gadget will be restarted, data will be deleted, which may take some time. At the end of the process, the device will boot automatically. The whole process usually takes no more than 5-10 minutes.

Features of OS reinstallation

The Android operating system is the most widespread and functional software for mobile devices. In addition, it has an open source code, which allows even amateurs to change and adjust the “axis” for themselves.

But despite all its merits, it is prone to glitches and errors. Therefore, the need to reinstall Android is a matter of time.

And if everything is clear with Windows and there are no special problems with reinstallation, then the mobile OS is not so easy to reflash. If reinstalling the OS on Android is wrong, you can ruin your phone.

If you decide to reinstall Android on your phone yourself, then you first need to familiarize yourself with a number of nuances and possible problems.

The process of reinstalling Android on a smartphone or tablet may vary depending on the manufacturer and model, as well as the firmware.

Features of OS reinstallation

For modern smartphones, the Android operating system is the most common; it has many useful functional features. The main plus in the case of an independent firmware change is open source code, which helps to make changes and adjust the system to personal needs. Despite the many benefits, Android is exposed to a large number of system errors and other violations while running. This leads to the fact that the process of reinstalling the OS is only a matter of time.

Compared to the operating system for a PC, it is more difficult to make a reinstallation like this on a mobile device, there are many subtleties that you need to know and take into account. If the action is performed incorrectly, the smartphone may be completely damaged and its performance will disappear without the possibility of recovery.

If a decision is made to make an Android flashing on your own, then you should understand in detail the preparatory work, possible problems and subtleties. The procedure may be slightly different, it includes certain features that are caused by the firmware, as well as the smartphone model:

  • Fly. the equipment of this manufacturer for a long period did not have the possibility of flashing, since the creators of smartphones did not make any updates. Recently, users have been able to reinstall the operating system, but the version will be higher than 4.0.
  • Samsung Galaxy. you can carry out the process of reinstalling Android in these devices using standard methods, setting the desired parameters in the settings or using a separate software called Samsung Kies. Third-party utilities are not recommended for installing new firmware, at least while the warranty period is valid.
  • Lenovo is a company that allows the user to manually update the system and flash the smartphone. In this case, the process depends on the architecture of the chipset. In this case, before starting the task, you must study the instructions.
  • Sony Xperia. the reinstallation is carried out only through a special software called Br The process of reinstalling the system

Before reinstalling the system on your smartphone, it is recommended to back up the data by transferring them to external drives or PC. Any mobile devices include the ability to copy information in the standard functionality. This allows you to save not only photos, messages and contacts, but also certain settings. When replacing firmware or system updates, always copy materials.

Reinstallation of the OS can be carried out using different methods. Among the current options, the following should be highlighted:

  • Reinstallation via PC using a USB cable.
  • Through the Recovery Menu on the mobile device itself.
  • Automatic Reinstallation.

All options can be used to install official assemblies, as well as custom ones. Many smartphones have the option of using the Hard Reset option, which helps to reset the settings to factory defaults without affecting the Android kernel. Often, this procedure helps to remove viruses, system crashes and freezes.

Resetting your phone to factory settings

In order not to perform a complete reinstallation, but to remove performance problems, errors that may occur while the smartphone is running, you can use the Hard Reset option. To perform actions, you must:

reinstall, android, samsung
  • Go to the smartphone settings menu and select the “Backup and reset” function.
  • Check the “Reset data” section, after it there will be a message that all user settings are being deleted. Give an agreement and activate Hard reset.
  • After that, the OS is reinstalled and all parameters are reset to factory defaults. In this case, Android version and kernel will not be affected.

Using the described method, you cannot install a new OS version or install custom firmware.

Self-flashing and updating

There are two ways to update the firmware of a smartphone or tablet: manual and automatic. But the likelihood of failure, albeit low, cannot be ruled out.

Preparatory actions

You can reflash the device using a PC. First you need:

  • Read the instructions for the gadget.
  • Examine the algorithm of actions required to reinstall the OS.
  • Download and prepare suitable firmware and drivers, special software, for example, acmeuninstaller, and hardware.
  • In case of failure, create a system backup. Otherwise, it will not be possible to restore it by any means.
  • Fully charge your phone or tablet. This is one of the basic requirements for flashing. And the phone itself or the tablet “will not agree” to such actions if the battery level is below 80%.

Reinstalling Android via “Recovery Menu”

In some cases, the smartphone user does not have the ability to connect to a computer or there is no desire to deal with all the intricacies of the firmware via a PC. In order not to use third-party programs, it is recommended to use the software built into the smartphone called Recovery Menu.

Before starting the steps to reinstall the operating system, data is backed up to external drives. After that, you need to do the following:

Turn off your smartphone and activate Recovery Mode. For this, a combination of keys is used, which differ depending on the brand and model of the smartphone. You can find out the details from the official manufacturer. For example, on Samsung phones, they use the Home button to turn off the volume.

  • In the utility menu, click on “install zip from sdcard”.
  • You need to specify the address to the archive with the new firmware, which should be placed in the smartphone’s memory in advance.
  • If the work is done correctly, the phone will restart automatically.

When performing the actions, you need to make sure that the mobile device has enough charge to complete the firmware. It is best to keep your mobile phone at a power source at all times in order to exclude possible malfunctions and errors due to an incomplete installation process.

How to Reinstall System on Android on Samsung

Any operating system starts to work incorrectly over time. And it doesn’t matter at all how expensive and high-quality the device was bought. The well-known Android OS is no exception. If such problems start, you can take the device to a workshop or reinstall Android on your phone or tablet on your own.

Installing the software required for the firmware

To flash a gadget using a computer, you need preliminary preparation and an arsenal of software, plus drivers. All this is recommended to be downloaded from the official website of the company. the manufacturer of the flashing smartphone. Otherwise, the smartphone may “die”. Remember that you need to select the firmware in the same way as the driver. exactly for the model of the “smart” phone.

One of the useful utilities for flashing is Mobileuncle MTK Tools. She asks for developer access.

After obtaining the development rights, you need to download the “CWM-recovery” corresponding to the specific model that you want to flash. Then you need to “transfer” the downloaded archive to the device’s drive. In this case, the memory “sewn” into the phone is not a reliable storage.

Note: this application is tailored for the chipsets released by MediaTech.

Only after completing the above steps should you run the program, which will automatically find the “CWM-recovery” saved earlier and ask for confirmation of the update. To confirm the action, click “OK”.

Installing custom firmware

To update the OS, the user needs to get ROOT rights. This often requires unlocking a bootloader called the bootloader. Exception. cases of using additional applications, for example, “King Root”.

It will not be difficult for owners of phones from HTC, Huawei, Sony, Samsung to unlock the “bootloader”. The main thing is that the actions correspond to the instructions. But with products “made in China” and with devices that are tied to a specific operator, everything is much more complicated.

Attention! After independent “experiments”, there is a possibility that the smartphone (even if it is good as the HTC U11.4 / 64GB) will no longer start. And even if the device is still under warranty, then most workshops will evaluate such a breakdown as not guaranteed: the user will have to answer for the consequences on his own.

Before you start unlocking Bootloader, it is recommended to back up your data and save the resulting files to a laptop or PC in order to be able to return to the starting point and restore the system.

When the reserve is safe, you can proceed with the following actions:

  • Download “Android SDK”: It is free to download from the official website.
  • Install the necessary drivers: determined by the Windows system or searched on the manufacturer’s website.
  • In the program “Android SDK” find “SDK Tools” and find the desired “archiver” (Zip-format is preferable).
  • Unpack the archive.

There is another, simplified version. “SDK Manager”, which is located in the utility directory. In the list that appears, click on “Android SDK Platform-tools and use” Install Packages “. The next window will pop up, you will need to accept the license. When the installation is over, you can close the window.

Note: if a software window appears and disappears immediately when you try to start it, you need to install Java from an officially confirmed site.

You will also need to download individual drivers (for example, for Huawei there is a utility called “HiSuite”, and for HTC. HTC “Sync Manage”).

  • Enter “About phone”. the section, which is located in the general settings.
  • Briefly click on the displayed build number until the smartphone notifies the user that the options for the developer are open / available.
  • Return to the settings and find the item that appears for developers there.
  • It is recommended to select “USB Debugging”, and if the “OEM Unlock” option is also available in the menu, install it as well.

In order to unlock Bootloader, the user will need a code that is available on the manufacturer’s official website. To do this, the owner needs to enter the device ID. This information is indicated on the packaging of the gadget or in the documentation. In some cases, you will need IMEI to get the code.

There is data. it’s time to “unlock”: Turn off the gadget ⬇ Enter the “Fastboot”.mode (for this you need to hold the “power” “volume down”) ⬇ Connect the phone using micro USB to a laptop ⬇ Open “Android SDK” ⬇ Platform tools ⬇ Press and hold “Shift” ⬇ Open context menu ⬇ Go to the window for commands

In the command window, designate the one that is suitable for a specific device, for example, fastboot oem unlock personal code provided by the manufacturer. for HTC (for example, ONE X10 DS) or fastboot flash unlock unlock.bin individual code for LG.

If you need to confirm the manipulations done on the phone (for example, LG X POWER), use the volume button to select the answer “Yes” and then press the power button without pinching it.

After a while, the Android icon appears on the display. This means the bootloader is successfully unlocked.

Use the “Vol” “Power” buttons to select and confirm the reboot function. The device can turn on for 10-15 minutes.

To get the rights required for custom flashing, use apps like “SuperSU”, “KingRoot” or similar Android software. For those who like to “use” custom versions of Android firmware, such an instruction for the “helpers” application is a great option for upgrading equipment.


Before starting the firmware, a Backup is mandatory (backing up data and returning it to its original state). This procedure is not difficult to do on your own.

First of all, unpack the two files that are contained in the corresponding archive on the SD-card into a directory called “script”, which is located in the root section.

The drive must be reformatted to FAT32 (just FAT. not suitable for androids) and inserted into the “script” directory. Remember that the gadget must be disabled when formatting and transferring the backup script.

After that, the boot files will be downloaded to the flash card. The signal for the end of the process will be the appearance on the display of inscriptions about its completion, and the drive is allowed to be removed.

Then you need to transfer “u-boot.bin”, “wload.bin” and “env.bin”, and then. change two of them in the firmware. “u-boot.bin” and “wload.bin”, without changing the name.

Attention! You need to transfer data to a PC or laptop. They contain information that will be useful when downloading a new “firmware” version.

The user has the opportunity to automate the backup procedure using the appropriate software. In this case, there is no need to identify files by their importance, track their changes, and transfer to another device, which saves time.

There are many applications developed for this purpose, but to install some you need to spend money, while others may not work correctly, which may cause the phone to work worse after flashing. But there are applications that work like a Swiss watch, and are available to the user for free.

3 handy backup apps:

  • Super Backup. fast and convenient software. will help you back up and restore data, applications and smartphone settings. Note that you may need root access to use it. In addition, you have to pay for the premium option, but this is not at all necessary. When paying for a premium, advertisements that “pop up” in the free version are disabled. Otherwise, they are no different.
  • Helium App Sync and Backup is available in a paid and also available at no cost option. The first one allows you to use a cloud storage, plan a backup, and relieve the user of advertising banners. There is no need to pay for basic functions. SMS, call log reservation. There is no need for rooting for the application, however, “disenfranchised” users will have to install an additional program for the application to work.
  • Ultimate Backup is a universal mobile software. Bonuses of the paid version are the scheduler and restore a copy from the cloud. The free version backs up files that are located on the local storage, is equipped with an uninstaller, a task killer function that allows you to terminate the process forcibly, as well as clearing the device from the cache.

Note: when backing up, as with flashing a device, take into account the battery charge. It is recommended to put the device on charge, for example, connect to Xiaomi Mi Power bank.

How to flash an Android smartphone: 5 steps

The smartphone has become “buggy”? Just want to upgrade it? The mobile phone can be reflashed. This article discusses methods that will help you properly prepare an Android gadget for flashing, as well as ways to change it through a PC or laptop. In addition, we considered the possibility of flashing a “smart” phone without additional “hardware”. Read on to resolve this issue yourself.

Flashing an Android smartphone using a computer

It is more convenient to “flash” a gadget via a PC. For users who work with Windows, starting from the seventh version, it is easier to solve the problem. They are either not required to identify the device, or the system will offer to automatically find them on the network.

Important! Regardless of the brand of the gadget, be it Lenovo or LG, software downloaded from unofficial sources during installation can lead to the “death” of the phone.

When flashing a phone via a PC, you cannot do without backing up files. To carry out this operation, you must:

  • Run the previously downloaded CMW-recovery, sharpened for a specific smartphone model.
  • Click in the menu on the option that makes it possible to save the current ROM.
  • Wait until a window with the “name” of the forthcoming Backup is displayed, identical to the creation date (the file name can be edited by the user if desired).

Then the device will automatically reboot. Next comes the process that does not require user intervention.

Note: Is copying taking too long?. Not scary: the time it takes to complete the task depends on the amount of information being processed.

When the backup has finished, the user should go to CMW, find the “Backups” section there and select the appropriate file from the list.

Another useful program for PC is Mobogenie, it will help you save SMS, contacts and media files. Using this software is quite simple:

Install it on your computer ➡ Connect your smartphone via USB ➡ Wait until the device is detected and click “Backup” (after the files will be transferred to your computer) ➡ To restore data, click “Restore” and specify the path to store the file.

It’s time to install the “flashing” file. The phone battery must be 100% charged. The gadget (for example, Samsung Galaxy A7 2017) is turned off. The entrance to the new Recovery is carried out by simultaneously pressing the Power Volume Up (the combination may differ for devices of different brands).

In the “highlighted” window, you need to click on “Reboot System Now”, then. “Wipe data / Factory reset”. After. confirmation, and then. clicking on “Wipe cache partition” and again confirmation.

In order for the firmware to start and start installing, the user should click on “Install from sdcard”, and then on “Choose zip from internal sdcard”. After that, you need to find the previously downloaded archive, which contains the firmware.

All that remains for the user is to click “ok” and wait until the installation is over, after which the smartphone (for example, Samsung Galaxy J5) will need to be rebooted. The first boot after flashing may take longer than usual. This is normal.

Preparing for firmware

Competent firmware requires certain preparatory steps. It is necessary to take into account the hardware stuffing of Smart-mobile phones: the type of firmware, the amount of RAM, the assembly series (kernel) and the number. the version of the system developed to interact with the device. the operating system. These indicators allow you to choose a firmware version, whose installation will not lead to functional impairments when working with the gadget.

Updating the operating system through the manufacturer

Installing official Android updates, unlike custom firmwares, is no big deal.

The user must determine the version of the software that is installed in his phone: for example, the Samsung Galaxy J3 has a 5.1 version. In order to find the information you are interested in about the device, you need to go to the settings, select the “system item”, find the section “about the phone” there. When the list opens, the user needs to find and view the operating system, and look into the directory that contains information about when the security system was last updated.

Please note: section names may vary slightly in different Android generations.

Typically, the system notifies the user that there are updates for the corresponding model. But the notification may not arrive on time, or it may be accidentally deleted by the user. it doesn’t matter.

In the system options, you need to find the item “System update” and press the “ok” button, after which the updates will begin to be installed. Most often, the action takes place in the background. Upon completion of the process, the device will automatically reboot or ask for confirmation. After this updates will become available to the user.

reinstall, android, samsung

You may not be able to download the update. There are two explanations for this situation: updates for a specific gadget model are no longer released, or their latest version is installed.

Attention! If the system has not been updated, the smartphone owner is advised to wait for a second attempt. It may take more than one day.

The device will try to update the system automatically. As soon as updates become available, the user will be notified if this option is not disabled. If the user wants to retry the update on his own, then it is possible to do this according to the instructions above, however, earlier than a day after the last attempt, it makes no sense to do this.

Note: Manufacturer technical support for devices will end approximately 3 years after the release of the model. If the phone is “older than” 3 years old, then you should not expect updates from the manufacturer. In this case, those who want to upgrade the phone have only one solution. custom firmware.
