For what it's worth, I spoke with a guy over on XDA who said he was working on both a stock rooted LYZ28E ROM as well as a standalone no force encrypt boot.img for the new LYZ28E build. I'll keep you and everyone else posted on when it all gets uploaded.
So, late to the party because I have not been keeping up. I guess the (LMY47Z) build that says it is for Sprint is the same one for At&t? All of you manual flashers on the At&t network, have you gone to this build? I am still on (LMY47I), trying to decide a course of action. Currently rooted and have the non-encrypt bootloader on.
Edit: Looks like that Android Police article confirms this is for At&t as well, LMY47Z. I see on XDA someone posted the non-encrypt bootloader as well. Guess it is time to get to work backing up internal storage.
All flashed, rooted, non-encrypted, TiBu restored. Just lost my Zooper widget for some reason, the backup I did to Google Drive from my internal storage didn't seem to restore right. Oh well.
Kind of sad to see I am still dropping WIFI access though, was really hoping they would have fixed that by now.
