Nooononono.. ALL YOU GUYS NEED TO SEARCH FOR 4.3 firmware's modem file and install it when you installed 4.1.2 rom.. so first install 4.1.2 onto your device and then look for 4.3 modem file and install that, too. This is what you need to do!! Your IMEI will appear then right. This is because 4.3 firmware converts your EFS version to EFS v2 (originally you have EFS v1) and 4.1.2 rom's modem isn't compatible with EFSv2.. SO ALL YOU NEED TO DO to look for 4.3 modem and install it with 4.1.2 rom!! This is 4.3 modem's code "XXELJ2".
I hope i could help you! ( <-- if u have questions)

Sign Samsung Galaxy S3 SCH_R530U (US Cellular) 4.3
It's ROOTED (I have access to SU, Root Checker says I'm rooted) and KNOX is shut off/not running.. I have the developer options on.. When I insert a SIM (Searching for service).. When I don't put one in (NO SIM CARD)... I am not getting any prompts to enter an unlock code...

#1 Did I do everything correct...?
#2 If I need to downgrade to 4.2.1, where do I find it....?

PS... I was playing with the About device tab... I clicked on Kernel Version or Dive status a bunch of times and now I'm getting a notification in the shade screen...? (Face Palm -_- )
