Problem flashing to stock firmware - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

I have a Galaxy S4 Canadian version (Sgh-i337m) with Bell.
It was sent to Samsung to be repaired because the sim card stopped reading. They replaced the pcb and it was working when I got it back, but when I flashed to Bobcat rom v5.1 and it worked, but the sim card stopped reading 1 hour later, so I flashed back to stock 4.2 and the sim card worked, but the sound stopped working from my speakers, and wifi stopped working, so I flashed back to bobcat v5.1 and the wifi works again, but the sound still doesn't work. Flashed back to stock 4.2.2 and wifi stopped, along with sound again. And everytime I boot it says something about forcing kernel, or warrant bit: kernel.
this time I flashed it to the official stock firmware latest 4.4.2 and still no sound, and its slow, and it says Device Status: Custom
I flashed the phone with odin, and with the OFFICIAL firmware for my phone and bell carrier. Can someone explain the sound, and possibly the sim card issue (i also got a new sim card)

the warrant bit thing is probably caused by the non stock kernel that came with bobcat. also if you're jumping back and forth from kk to jellybean you might be having a mismatch in baseband. 422 would have MG1 while 442 is NC1.

No Sim Card Error after upgrade...

Hi guys,
Set the scene - was running a custom 4.3 rom, flashed Stock 4.3 rom and got everything working. During the day I kept getting a No SIM card error.... If I remove the SIM card and reinsert it was fine or if I rebooted my phone it was fine - but only for an hour or so. It got worse and more frequent as the day went by....
Unfortunately I can't get it to work at all now - permenant No SIM card!!!
When I got home I flashed an even newer 4.3 firmware from samfirmware for the UK (BTU version I'm unlocked) - baseband I9505XXUENA4 and the same for the build. I was hoping this may fix my issue, but NO still the same!!!
It's not the SIM card as it works in my Note2 and I think it must be software related somewhere as it only started happening after my flashing of stock etc yesterday....
Anyone have any ideas of what it could be???
• Do I need to flash a csc file or a different modem???
• Would going back to 4.2 help (I know this will void KNOX but don't care as my phone is useless as is)
Just some help would really be appreciated!!!

Please help me. Bell(Canada) i337 unlocked. No sound or wifi after I rooted.

I rooted my s4 i337 (bell, unlocked) and now I have no sound or wifi. I have been looking everywhere and have tried re-installing stock firmware, flashing kernel and I cannot get the sound or wifi working.
Info:
Phone:galaxy s4 i337 bell but unlocked
baseband: i337mvluemk6
kernel: 3.4.0-517283 [email protected] #1
knox says 0x1 and seandroid is enforcing.
android version: 4.2.2
When I update to 4.4 the phones lags too much to even use. 4.2.2 is smooth though. Data and texting work fine but if I try to make a call the phone freezes and dialer crashes. When I plug in headphones or try to watch a video or listen to sound the phone freezes and whatever app is opening the sound crashes.
Please help me.
Same problem I am having. Am working on solution as we speak. I may just go back to 4.4.2 as it worked fine for me. Long story as to how I ended up downgrading accidentally to get my phone working again lol. Will get back to you as soon as I figure it out. I am pretty sure we have to flash a different modem ( I am on 4.2.2 with I337MVLUAMDJ Fido Canada right now. Build number JDQ39 Galaxy S4 SGH-i337m)
Hey bud, I couldn't really fix the WiFI/sound problem so I just reloaded stock KitKat 4.4.2 back onto my phone and all is working very well again. I never really had a problem with lag or battery using 4.4.2 so I think I tempted fate enough and just went back to stock with root. Good luck and I hope you find a solution that suites you.

[Q] Very odd issue with Canadian Bell S4 and newer CM11 nightly builds even after sto

Hello everyone.
I recently installed the stock Rom on my S4 to ensure that my modem and base band are being properly updated.
The phone info now is:
Model Info:
SGH-I337M
(cureent version of CM I am using is M9)
Android 4.4.4
Baseband
I337MVLUAMDJ
What has never worked in the microphone without putting my phone on speaker phone during phone calls. Bluetooth works as expected.
However when I now want to go to a nightly build after M9 the radio modem turns off as soon as the screen is locked. This happened also when I went to M11 right AFTER I had the phone on the Stock rom. Th eonly rom that seems to not disable my radio and thus disconnect me from Bell when the phone starts to lock the screen is M9, every other rom after, even nightly builds will simply shut it off.
Is there a procedure for me to recover my pmicrophone use during phone calls without being in hands free speaker mode and what is more important a way to install new CM updates without the radio shutting off promblem?
Thank you!
