How To Relock The Bootloader On Asus Devices

Be it for flashing custom ROMs, installing a custom recovery, or gaining administrative access by rooting your device via Magisk, the possibilities stand endless. However, carrying out these tweaks has a few downsides as well. For example, you might not be able to use banking and payment apps due to the tripping of Safetynet [unless you pass SafetyNet]. Likewise, the WideVine L1 Certification will be degraded to L3. This will result in your inability to watch DRM protected connected [such as Netflix] in full HD. Not to mention the fact that a custom environment will always have a few additional bugs in comparison with its stock ecosystem. So in all these scenarios, the best bet is to return to the stock OS by removing all the mods and subsequently relocking the bootloader on your Asus phone. And in this guide, we will show you how to do just that. Follow along.

How to Relock the Bootloader on Asus Devices

The below process will wipe off all the data from your device, so take a complete device backup beforehand. Droidwin and its members wouldn’t be held responsible in case of a thermonuclear war, your alarm doesn’t wake you up, or if anything happens to your device and data by performing the below steps.

STEP 1: Remove all Modules and Root

First and foremost, you will have to unroot your device, uninstall all the modules, and remove custom ROM and recovery. While you could do each of these tasks individually, but a shorter path will be to simply factory reset the device and then flash the stock firmware.

STEP 2: Install Android SDK

First and foremost, you will have to install the Android SDK Platform Tools on your PC. This is the official ADB and Fastboot binary provided by Google and is the only recommended one. So download it and then extract it to any convenient location on your PC. Doing so will give you the platform-tools folder, which will be used throughout this guide.

STEP 3: Enable USB Debugging and OEM Unlocking

Next up, you will have to enable USB Debugging and OEM Unlocking on your device. The former will make your device recognizable by the PC in ADB mode. This will then allow you to boot your device to Fastboot Mode. On the other hand, OEM Unlocking is required to carry out the bootloader locking process.

So head over to Settings > About Phone > Tap on Build Number 7 times > Go back to Settings > System > Advanced > Developer Options > Enable USB Debugging and OEM Unlocking.
