- Use this tutorial only if your device is on unlocked bootloader, rooted and running a custom Recovery image such as TWRP or CWM.

- Move all your important files to your phone’s internal SDcard.
- If you want to backup SMS, Call Logs and some other data, use these tools for Android: SMS backup & restore | Call Logs backup & restore | APN Settings Backup & Restore | AppBack for Android application. The tutorial contains a step that will ask you to factory reset the device, it will delete the system partition and not the internal SD card. NOTE: if your device is already on an AOKP JB ROM then you can flash this custom ROM over it without ‘factory reset’.
- Also, sync your Gmail with the Contacts / People app. It will save all phone numbers and other data from your device.
- Enable USB debugging option for your smartphone.
- The battery of your device should be charged and showing that at least 50% power is left before powering down.
- We cannot be held responsible if you brick the Nexus or in case you lose important files. Read the entire post and don’t skip any steps listed below.
