While in TWRP were you able to flash the bootloader and modem zip again?
Not sure how you have a Factory Data Reset password set up,that's something you have to do from settings-security.
Guess still looking at baseband version unknown, IMEI corrupt, no sound and sim not found.
Fixing the IMEI should take care of the baseband unknown and maybe the issue with sim. Not sure of the sound, could try custom ROM to see if it software. Life would be easier if we could find Odin flashable version of NJ2 Firmware but doesn't exist.
Do you want to work on IMEI next?
