Default [Q] Reverting to stock; any shenanigans to be aware of?

My phone decided to stop getting a connection today[1], and since I'm running CM11 I figured I might try flashing back to a stock ODIN package. Is there anything I need to be aware of in terms of going back to CM eventually (bootloaders/modems/etc)? I remember when I first got this phone there was some confusion about bootloader versions, but I'm guessing if I flash a stock Kitkat ROM it should be okay with CM11? Thanks!

[1] I get a signal, ~ -75dBm, but no connection, and the same SIM works in another phone.
