Points to remember
- Before following the installation guide, create a backup of all important data of the phone using custom recovery.
- Enable USB Debugging on the phone to connect it with the computer and use Android SDK with it. [Navigate to Settings>> About phone. Tap on Build Number several times until a message appears saying 'You are now a Developer.' Now enable USB Debugging Mode by navigating to Settings>> Developer Options.]
- The Moto G should have above 80% battery charge to avoid power off during the process which could damage the device.
- The phone should be rooted with the latest recovery system installed on it. Also, it should have an unlocked bootloader.
- As the AOSP ROM is in beta stage, bugs are highly likely.
- The Android 5.1 Lollipop AOSP beta firmware works with Moto G 2013 aks 1st Gen. Flashing this on any incorrect variant might brick the device. Therefore, verify the model number of the device.
- After flashing the ROM if the device gets stuck on booting animation or experience boot loop then perform wipe cache partition and wipe dalvik cache for a few times before rebooting the device.
- Once the ROM is installed, users are advised to give 10 minutes to the ROM after the device boots up for the first time for better user experience.
