  1. Thanks for this, very helpful. Can I use this for a PC Mobile phone (Telus network)? If so, would there be a problem restoring the original by using the unrooted T989DTLUMC4 for Telus?

  2. hey i ran into a problem the TWRP recover file, it is in a IMG file and is not finding it on Odin, as your instructions say its suppose to be a TAR file,

  3. if using winrar or something, uncheck in the program setting the .tar extension and your file will be apear.
    when you reboot in recovery mode click recovery icon and the message will be apear look like “your not root dou you want to install…..”
