I tried as you have suggested your decrypted file. Unfortunately, I get an error when trying to run it via ADB in fastboot.
I've rooted when I first got the phone last summer using Revone method/tool. All worked fine and i had continued updating the OS a few times with stock rooted phones.
The last that i updated to was a stock rooted odex kitkat ROM found here http://forum.xda-developers.com/show....php?t=2676986
Only thing that seemed wrong was that I couldn't reinstall any of my apps requiring root. The error that would pop up is "Could not install to SD card".
Now, I have to say that I noticed that with some updates, it seems that new ROMS don't clean up the old files/framework even after fully wipes. It seems to back it up in some folders (sdcard0, sdcard00, sdcard000 etc). All though the sdcard folder seems clean and refreshed, the others mentioned had all my old files in there. Since I've updated to kitkat, I can no longer view these folders (I used to use Root Explorer, but now since the kitkat install - I can't). What caused me to notice was the fact that my storage, in the 'Other:' section, shows 20GB out of 32. So, I used ES File Mgr to see if I can create some space by deleting the so-called backup folders. I think that was a bad mistake because now, even after a full data wipe, I still can't:
* Install root-required apps
* flash the zip file you provided
* use the exe version of the zip you provided (still get an error with that as well)
* Clear the 20gb of data I don't need
* get back to the At&t carrier brand from the Developer's Edition that i switched it to back last summer.
Fortunately the phone works fine, but is this hopeless? Anything I can do to get this going again (really thing I messed things up)
Is there anything else I can try?
