Factory reset protection is getting several key upgrades in Android 15 to make it harder to bypass.

This article goes into more detail about how these new measures will actually work compared to the blog post earlier this year from Google. Namely:

  1. Enabling the OEM unlocking setting will no longer prevent FRP from activating.
  2. Bypassing the setup wizard will no longer deactivate FRP. FRP restrictions will apply until you verify ownership of the device by signing in.
  3. Adding a new Google account is blocked.
  4. Setting a lock screen PIN or password is blocked.
  5. Installing new apps is blocked.

      True! But it still hurts the resale value because users are likely to notice a device with broken secure boot if you were to somehow use it to forcefully flash a modified ROM.

      Are you proposing this mode could be used to somehow clear the secret data?

      My understanding is EDL mode can refuse to flash some partitions and some devices will not enter this mode if fastboot is working, which also enforces preventing access to some partitions. Most people who use EDL already unlocked the bootloader, but I don’t think this method works on all devices if the boot loader is still locked.
