Fixing "System Destroyed" While Relocking

You are here because you tried to relock your device after rooting it on stock OOS — and now it says "System destroyed". What to do?

Info

• This happens when you try to relock the device after uninstalling Magisk without flashing the stock OOS boot.img.
• If you locked the device, unlock it again (below).
• If it bootloops without entering fastboot mode while plugged into your PC: unplug it first, then force-reboot to Fastboot Mode with Volume Up + Volume Down + Power. Once it boots into Fastboot Mode, plug it back into the PC.

Recovery steps

Copy and run the following commands:

fastboot flashing unlock

fastboot flash boot boot.img

Note — Use the same version of the stock boot.img as the OOS version you were on. Make sure you are flashing the stock boot.img if you want to unroot — if you flash a patched boot.img, the device will boot with Magisk still in the system.

fastboot -w

fastboot reboot

This boots you into the system with the device unlocked.

Now you can relock

After it boots into the system, go back into fastboot mode and:

fastboot flashing lock
