So, what else did you already try ? Flash different version of modem ? Reflash stock ROM via custom recovery ?
Baseband version shows Unknown. Try reflashing your modem.

Download your modem flashable zip here https://www.dropbox.com/sh/d2ljv1ylvr9nvib/M7UzMgux4f and flash it again. If no luck try with a different custom recovery. CWM or Philz for instance.

yes flashed modem again with cwm rom, booted into recovery tried to flash modem I9305T_DVBLL3.zip.
should I try a different modem ? my phone model is I9305 not I9305T, maybe this is why its not working ??
I have the same situation when went back to 4.3 rom from 4.4 rockyard. Nothing helped. So I restored backup of 4.4... and everything works. I'm currently using this Rom without problems (old rockyard ported from Note).

I've been looking around for Custom Roms for the SGH-I537, and I always seem to find them. But when I go and attempt to install them through SafeStrap Recovery, it says its for everything but the JACTIVELTEATT, is there a custom ROM somewhere specifically made for this device?

There are not any ROMs created specifically for the i537. However you can install TouchWiz-based ROMs built for the regular S4 and just flash the Masterpatch afterwards.

I've tried doing that, after flashing the masterpatch and so on, I boot the phone with that Rom-Slot active, and it looks JUST like my stock rom with the same data and everything. Just I can not use the Wi-Fi or data.

You're doing something wrong because ROM slots cannot share data, so you are just booting your stock ROM. Are you sure you're using the correct version of SafeStrap for your firmware?

Stock ROM, with all my data, but my Network AT&T is not accessible. Both, data and to call. I tried entering the VPN for it manually and it didn't work. Everything also loads extremely slowly. My ram gets cut in half. And a whole bunch of other minor stuff.
I've tested this with multiple Roms.

Any ideas or has anyone seen this??

Annnnnddd flashing stock gets data on stock but not on the ROMs. Hm. It seems only stock based ROMs work

If you are on Stock Touchwiz 4.4.4 you will need to flash a 5.1.1 ROM in order to use the newer modems and bootloaders. IMEI number can be lost if something happens to the EFS partition. You could try to flash a stock firmware for your device model and your region; a factory reset may also be helpful, though my guess is that there isn't much that can be done unless you have a back up of the EFS partition which you can restore.

appreciate the very fast reply. thank you.
I am hesitant to upgrade to 5 as i am not sure if i can return to 4 if need be or if it may be easier to fix this mess in 4 perhaps.
I wonder if its possible to use some1 else backup and then change the imei parameters in the efs folders. at least then all i have to worry about is getting an imei changed back to my own. i doubt its that simple tho of course. :s its been a long day.

If you haven't triggered your KNOX counter then you will have to flash an entire firmware because the modems and bootloaders require the ROM to be of the same firmware.

This may be dependent on what ROM you are currently running. The files I provide are unmodified as I have simply extracted them from the Odin flashable firmware.
