Then I wiped data/cache and flashed 4.2.2 again, same problem No wifi, no sound, etc. Thought I would try CM11 again, Wifi works but no sound. Flashed 4.2.2 again and now I am here.
I have searched the forums and people have been talking about modems/radios and that could be the problem. But I have no idea where to start because I haven't found much for the SGH-i337M. Any help would be appreciated
Build number is MDJ and Baseband is MK6. Are they supposed to be the same?
The rom you have has the 4.3 which cannot be downgraded to an older rom (MDJ).
What you need to do is to get a hold of the specific 4.3 MK6 odin flash firmware for
your phone model number which is available at http://SamMobile.com
Then go into recovery and wipe data, cache, dalvik cache, system and last but not
least perform a "factory reset" in recovery before Odin flashing the official 4.3
MK6 stock jellybean firmware.
After that, the phone will work fine, but it will not be rooted and it will not have a
custom recovery like twrp or cwm so you will need to start all over again rooting
and flashing cwm or twrp custom recovery if you want to flash 4.3 custom roms.
Have a great day, enjoy!
Don't forget it takes less time to click the "THANKS" button than to type "thank you".
(unless you type very fast).
