I'm new to smartphones and all this tech in general. I recently purchased a Ulefone U7 smartphone and stupidly flashed the latest Android v4.4.2 KitKat ROM via the Ulefone site using SP Flash Tools. Now the phone says my IMEIs are invalid for both SIM slots and I'm unable to change them.
I've tried changing them via the Engineer Mode AT+ commands but get the message "This command is not allowed in UserBuild" or something similar.
I've also tried changing them with Droid Tools v2.5.3, but nothing sticks.
I'm unclear as to whether root is required or not. In any case, I can't root with SuperSU.
I've tried most things to root, but the only thing that seemed to work was VRoot. I then tried replacing VRoot with SuperSU via both methods listed by gammelobst in a previous post, but seem to be missing something.
Trying these methods, I run the .BAT file and get the message "/system/bin/sh: su: not found" and am not prompted to grant root to ADB.
Can someone please help me rescue this phone from being a paperweight? I'm all out of ideas and all the lingo phones use is new to me.
Thank you from the bottom of my utterly exhausted heart...
