HELP. I9505 IMEI= null/null, baseband = unknown after attempt to update baseband

I was trying to update my baseband today and ran into some troubles. After flashing a stock ROM with the correct modem (or, at least I believe it was the correct one), my sim isn't detected, baseband shows up as "unknown", wifi doesn't work and the IMEI is listed as "null/null". I have no idea how this happened, but I'm scared I may have somehow bricked my phone (which I desperately need tomorrow - oops).
Is there any known fix for this?
It's an I9505, I use the German carrier 1&1 and was flashing the XXHOJ2 baseband. I also did not make an EFS backup (oops #2).
Any help would be greatly appreciated.
EDIT: I just flashed an old nightly of CM12 and now suddenly everything works again. No idea how that happened, but yeah... the problem is fixed. If any mods out there could delete this thread, that would be nice.

samsung galaxy s4 Unknown IMEI Unknown Baseband Unknown Network

i was using this phone for like 3 years
just recently it started doing this where it would show no service and a quick reboot would fix the problem
now as of friday the day after thanksgiving the phone shows null everything no matter how many times i reboot and ive put new simcards in to check if that was the problem and it wasnt the simcard
i doubt the efs files are corrupted because i only flash stock OTA updates through odin no custom ROMS and ive taken very good care of this phone and follow tutorials to the "T" when i do anything of that sort
but anyways ill list everything that is null/unknown so you have a better idea of what the problem might be and in advanced id like to thank you for any help you may give me
i just want to give this phone to my mom to use.. its crazy right when im done paying it off that it stops working its basically an ipod now hopefully you can help me fix that
here we go....
