To eliminate thoughts and possibilities. ..
Does your phone work right now?
Can you restore your saved backups in recovery?
Can you get any other aosp roms to run?
Any other touchwiz roms that is highly modded work? Not stock based.
When did you buy your phone?... they have made a couple different s3's and the new ones have extra prevention to stop us from rooting and hacking the phone... maybe there is yet another new phone that's just getting released.
I recently bought this phone at best buy, and I think you are correct, I heard that they have some newer s3's that dn't like the roms like your saying.
I can save backups
The phone works fine, as I have had touchwiz roms installed and a couple of aosp roms on, although they seem to give issues.
This is my compiled list so far of roms that I have tried:
Roms with a black screen after samsung logo:
-CM11 nightly latest build - blank screen after
samsung logo
-Beanstalk 4.4 nightly build - black screen after
samsung logo
-Cm10.2.0 - bails out on install
-CM10.1 - bails out on install
-Carbon Rom 4.4.2 - black screen after samsung logo
Roms that have worked fine:
jdsingle MK5 Tw rom
-ODIN Backup for --> BOOST MOBILE SPH-L710_MG2 (tw)
- no isues at all
-stock rooted MD7 rom (tw) - no issues at all
-stock rooted MG2 rom (tw) - no issues at all
-VanirAOSP nightly - had a few issues and glitches
-Fox - Installed fine but had no wifi or 3g/data
-Bam Android - no data/3g
-Carbon rom 4.3.1 but has a few glitches
Conclusion, every touchwiz rom I have tried just works without issues.
Most if not all that I can recall of the aosp roms have the APN issue, so I don't have data on those.....and a few other quirks, but I can worry about those later, need an APN fix first.
Since I have never had to do an APN fix before I am nt sure what steps to take to do it.....so does anyone know a way on aosp roms to fix the apn?
In the mean time I am going to try one last ditch effort at this as a work around, in hopes they didn't bypass the MG2 update and go directly to MK5......I am going to flash back stock un-rooted, except the firmware updated, and as I said hope it will do incremental updates and not go directly to mk5.
If it does indeed go directly to MK5, then I will be holding off and put on pause, JUST to make sure there are no hardware issues before I void warranty......I figure a good month will do the trick, although I realize there are n guarantees it won't happen down the road, but still, better to be safer than sorry.
