Restore Internal Memory of Galaxy Nexus after Bootloader Unlock Wipe [Tutorial]
Galaxy Nexus

Unlocking a bootloader normally wipes the data partition in a Nexus device. It is possible for users to root a device without unlocking the bootloader but this is a tedious process. Therefore, if the easiest way to root the Nexus is by unlocking the bootloader, it would be useful if there were also a method to recover data after it has been wiped. Fortunately, XDA forum member Wartickler has a solution.

This method allows for the scanning of drives and recovery of wiped data. The accompanying post indicates it is compatible with any device that has an internal SD card.

Follow this tutorial to recover wiped data. IBTimes UK warns its readers it will not be held responsible for any damage to the device while following this process.


    • Ensure BusyBox is installed on Android device
    • Enable USB debugging and install a recovery tool, such as the Piriform Recuva app
