It is required to disable the FRP option, as well as enable the “factory bootloader unlock”. As soon as the status changes to the one in paragraph 1, you can start installing TWRP.

Why is there no “factory bootloader unlock” option

For security reasons, the feature is not available if the phone has not been used for 7 days. If the service life is less than 168 hours or the device has been rebooted, the item will not appear. Sometimes this is also facilitated by switching to airplane mode, removing the SIM card and resetting to factory settings.

In some smartphones, more often new products and / or flagships, bootloader unlocking is temporarily not available. In this case, you need to wait for the item to appear in the settings, possibly after updating a certain firmware.

To speed up the appearance of the “factory unlock” button, on some smartphones, for example Galaxy S9 / S8 / Note 8, the reverse time shift also helps. This requires:

  • Go to the settings section.
  • Select the item “time and date”, where to disable automatic change of parameters.
  • As manual editing of parameters opens, you need to set a number that is 7 days higher than the current date. For example, rewind 1 month, so that the smartphone thinks that it has been working for a month.
  • Then you need to open the section for developers, where you can disable the automatic system update option.
  • Then return to the settings and go to the standard item “software update”. It is required to disable automatic download, and check for updates manually.
  • After restarting the smartphone.
  • As soon as the device starts the OS, the item “factory unlock” will appear in the section for developers.

How to remove bootloader lock

  • Open developer tools. Press 7 times on the firmware build number, in the “About phone” section.
  • Next, find the item with the factory unlocked bootloader. “OEM unlock”. Place the switch in the active state. Item missing? See the solution in this subsection.
  • Enter bootloader mode. To do this, turn off the power of the smartphone; hold down the Volume Down, Home and Smartphone On buttons at the same time. After the greenish screen appears, hold the “Volume up” button until the phone boots into bootloader mode.
  • Notice the FRP LOCK and OEM LOCK lines. If the value is “OFF”, there is no line “RMM STATE: Prenormal”, the bootloader is open and ready to install TWRP.

If the state is “ON”, the bootloader is closed, and TWRP cannot be installed. See this subsection for details.
