I got it, and kept it off to charge it up - seemed to top off in a reasonable amount to time - not too quick, not too slow. Once charged, I hopped on it and, woah, she definitely had something corrupted.
I went into eff it mode, pulled down all of her pics/vids/audio/dls/snaps/etc. and proceeded to root it and install a recovery. Having only owned my GS3, I have only ever been exposed to 4.x versions of android. With this device having a 2.x flavor onboard, I felt the rush of discovering something old and admiring changes for the better and observing trusted old ways of the wise.
I actually struggled a bit finding a good way to root it and get a recovery installed. I ended up following Section 4 herein and got CWM installed. From there, it was gravy getting AOKP 4.2.2 installed.
I ran some testing over the last few days, just to see how the battery survived this current generation version of Android on some older chassis' hardware. Frankly, I am really surprised that it lasted as long as it did. I kept WiFi on and have a reasonable amount of apps installed (the norm social media, gapps, etc.). I think it is safe to say that her battery and hardware are very likely fine.
Of course, real-world use will predicate a much shorter battery life. But, I think it will work fine for her, for now. And, yes, she wants it back... I was hoping she would say 'just keep it' as I was looking forward to having another droid to play with, besides my main phone (GS3) that I can't afford to be playing with too much, as it is my link to work here at the home office.
Anyways, wanted to drop a note confirming a positive experience with the Fassy and Android 4.x. Peace. Out.
