While these tweaks do bring in some uninvited risks, but more often than not, you could easily repair it right on your own. All that is needed is just an unlocked bootloader. If you checkmark that requirement, then you could easily flash the stock firmware via Fastboot Commands and bring the device back to life. But what if the device is bricked in a locked bootloader state? Well, in those instances, you wouldn’t be able to make use of the Fastboot Commands. Fortunately, there’s now a leaked internal build available for Pixel 3 to 5 series devices that could easily be flashed on a locked bootloader as well. So if you are currently on the Android 12, and wish to rollback to the earlier stable build, then this guide shall help you out. Given here are the detailed instructions to rollback your bricked Pixel 3/4/5 from Android 12 Beta to Android 11 on a Locked Bootloader.
