4. Power off the phone. Hold Volume Up + Volume Down and connect to your PC via USB cable to enter the Bootloader Unlock screen.

3. Once inside TWRP, go to Wipe > Format Data and type yes to remove factory storage encryption.
4. Flash the multidisabler zip via Install to prevent bootloops and stock recovery overwrite, then reboot to system.
