  • Your HTC one MAX should be rooted and have a custom recovery (both CWM and TWRP Recoveries will do. Updated to its latest edition).
  • Backup all your important data before proceeding for just in case something goes wrong. You can create Nandroid backup which will later help you reinstall everything that you may lose during the process.
  • For application backup you can use the Helium tool for Android.
