  1. This worked on my Samsung Galaxy S4 (Model:SPH-L720, Software:VPUAMDL, Android 4.2.2) after attempt #2. I was able to use Titanium Backup with root access so I know rooting was successful. Strangely, however, after I rebooted the phone root access was gone and I can no longer root it using this method.

  2. Thank you so much ,

    CWM failed my Samsung Galaxy S4 (Software Version:L720VPUAMDL; Hardware: L720.08; Model:SPH-L720; Android 4.2.2; Baseband:L720VPUAMDL; Build JDQ39.L720VPUAMDL).
    I directly applied this approach without unroot(No idea how to restore to VPUAMDL kernel), Done!
