So, if you are looking out how you can get this custom ROM running on your device, then here is the tutorial for you, before we actually proceed, please keep in mind that custom roms/nightlies are meant to be for those only who like to play with their device and always keep tinkering their phone with new operating systems. These ROMs may not be kept for every day use as these contain a lot of bugs until there is a stable build out there, so it is highly recommended not to mess with these if you are a noob or if you don’t know much about the custom ROMs. Follow this guide to the letter in order to prevent any mishap.

Disclaimer: The methods involved in flashing custom roms and rooting your phone is highly custom and may result in bricking your device, and has nothing to do with Google or the device manufacturer that is Sony in our case. Also rooting your device will void its warranty and you will be no longer eligible for any kind of free device services by the manufacturers/warranty providers. In case of any mishap we may not be held responsible. Follow these instructions to the letter to avoid any mishap or bricking. Make sure that whatever you do, you are doing it at your own responsibility.

What you need to do before flashing this ROM:

This ROM is only for Sony Xperia Z. Do not try this on any other smartphone.

      1. Your phone’s bootloader must be unlocked. Unlock it here.
      2. Your phone must be rooted and have the latest TWRP recovery installed. Follow the complete guide here to root and install TWRP.  Root Sony Xperia Z | Install TWRP Recover on Sony Xperia Z.
      3. Make sure that your phone’s battery is charged at least over 60%. This is highly recommended in order to prevent any power issues during the flashing process.
      4. Do not forget to backup your current ROM/System using the TWRP recovery. This is highly recommended in case the new custom ROM does not satisfy you and contains a lot of bugs, you can immediately go back to your previous system using the Restore option in the TWRP recovery.
      5. Make sure that you backup your important media content, contacts, call logs and text messages. This is highly recommended as you will have to wipe your phone before flashing this rom for clean installation.
      6. After backing up all the important stuff, boot intoTWRP recovery use the wipe options and wipe data-cache-dalvik cache. This is highly recommended to achieve the best installation results and best ROM functionality.
      7. Alright! Once again I insist that follow this guide to letter!
