After I flashed 5.2 - mine hung at "dual core" screen.
I had to flash a kernel from here http://xdaforums.com/showthread.php?t=1520417
My phone can't take anything higher than 1.3 - I had this issue in an earlier build also. Can anyone verify what the OC is set to in 5.2 build?
It's set to 1.4
I just tried again to flash 5.2, this time over a nandroid 5.1 backup. I got to the Android "optimizing apps" part, and then it said "finalizing boot". Rebooted my phone and hung indefinitely at Dual Core screen. After that, I can turn it on and sometimes it will hang at Dual Core, sometimes at CM9 boot logo.
In any case, something is weird about 5.2. I have been using every update, flashing using Joker's v3 recovery, and haven't had any problems. This update doesn't like my MoPho.
Everything here works just fine. I'm using the old photon3 recovery.
