Hello everyone,

So I wanted to go back to stock 4.2.2 from CM11 which went fine, then I updated to 4.3 because I wanted to use a new ROM. Well I messed during the flash and when it booted back into 4.3 I had No wifi, no sound, no calling and if I tried playing a song it would say it wasn't supported.

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

Thanks

-Update-

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.

Thumbs up Wow, SO MANY thanks to you Misterjunky
Misterjunky,

I *just* created this account solely for the purpose of saying THANK YOU SO MUCH a million times over, after formatting 'data' 'cache' 'system' and performing a wipe of data/factory reset in ClockworkMOD recovery I was finally able to fix this exact same issue with my Telus branded SGH-I337M, It had me stumped for well over the last 48hrs. To anyone out there reading this who is having the same problem and would like step by step screenshot instructions and/or a dropbox link to the official 'TLS I337MVLUEMK6' [Telus 4.3 Jellybean Stock Firmware] please contact me at:

edit: As a new user it will not let me link to my email account, please use this site to message me. Sorry.

I will check this account daily at midnight EST and reply to all serious inquiries as a token of paying it fwd and saying thank you.

Misterjunky - you sir, are the friggen MAN.
