Flashing ROM is illegal as well as risky so you should take some necessary actions before going to flash this ROM to your Z3 phone.

  • Backup each and every important file you have in your phone to your PC or any other external drive. You can sync all your contacts to Google account and restore them when finished installing ROM and use Titanium backup application available on Google Play Store to backup your important apps. We can’t be claimed if you use any of your important data.
  • In steps to install ROM you will notice that two important steps are there “Nandroid Backup” and “factory reset”, these two steps are very important. Nandroid Backup will make a backup of previous ROM so if anything goes wrong you can go back to the previous ROM easily and Factory Reset is important before removing the previous installed ROM.
  • This tutorial and files listed in this tutorial are only for Sony Xperia Z3 only. Do not try to install or use this process on any other phone or device as it may brick your phone seriously.
