Uh oh...
After cm11 nightly july1, NO SERVICE!
I assumed this would be modem related stuff, so I reflashed the NAE modem - nothing. I flashed back to cm10.2 - nothing. I flashed back to original full MDC stock rom - still nothing. It just get's stuck on "preparing network" forever. There are rumblings here & there that clockwork recovery ( touch in this case) is corrupting the efs partition, which may or may not be the cause of this problem. In any case, I can't seem to locate an efs jflte Sprint image to restore from to test this theory because it's not included in flashable roms, and I wasn't even aware that it existed until now. If I can't get this fixed somehow, my "phone" will now be a very expensive wifi screen. Any insight into this issue is mucho grande appreciated as this is a showstopper for me.
