  •  Backing up Data :- We are about to flash a new custom Codename Android ROM to our Galaxy Nexus which wipes all the data stored on our phone. So backing up our data is a safe hand advise. Begin with your SMS, back them up with the help of app “SMS Backup and Restore”. Do sync your contacts and call logs with Gmail, store all the images, videos and text to any external device. Write down your phone’s APN and MMS settings at a safe place. Sometimes due to a faulty process, anything goes wrong, it’s better we have the settings for our data connection. Do back up every bit of data you have stored on your phone’s internal memory. As this flashing requires you to unlock your phone’s bootloader so also back up everything on your phone’s SD card.
  • Now we suppose you have an unlocked bootloader on your Galaxy Nexus i9250, if not please do so. Unlocking the bootloader is very most essential step to proceed further. Do not proceed if you don’t have an unlocked bootloader, doing so can brick your phone. Unlocking Bootloader voids your warranty so proceed at your own risk.
