How to Install VRBLI5 Android 4.1 on Verizon Galaxy S3

  1. This procedure will wipe all your apps, data and settings (but it will NOT touch your SD cards, so don’t worry about those). Backup your Apps and important data — bookmarks, contacts, SMS, APNs (internet settings), etc. This Android backup guide would help you.
    NOTE: Don’t forget to at least note down your network’s APN settings, which are required to make mobile data work. Go into Settings » More » Mobile Networks, click on the APN that is in use, then note down the setting for each field. While APN settings should be automatically restored from network, you can enter them manually if needed to make mobile data work. You can also find your APN details → here.
  2. [Important!] Unlock the bootloader on your phone by following this guide. This is necessary and will void your phone’s warranty, however it can be relocked (using the same app used for unlocking it) when needed to get warranty back. Skip if you have already unlocked the bootloader.
  3. Install ClockworkMod recovery on your phone by following the guide → here. Skip this step if ClockworkMod recovery is already installed on your phone.
  4. Download the ROM.
