Write Fail Error in Odin on Galaxy

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?

Now, boot back into TWRP and flash the SuperSU update zip and Reboot. Open SuperSU and update its Binary and disable Knox. Once you get the phone set up the way you like it,boot bacvk into TWRP and make a backup. It will give you the option to save it to SD card.
Things I keep on PC and phone SD card.
NJ2 bootloader and modem zip
NJ2 System image zip
Stock recovery zip
SuperSU update zip
TWRP backup.

Pretty easy and you have a backup made if something goes wrong. Think of it like a restore point on a PC. Instructions same if using TWRP.
1- Download rom and Gapps zip files and copy to SD card.
2- Preform wipe (factory reset)in TWRP.
3- Select Install zips(rom+Gapps)then flash.
4- reboot system
5-Set phone back up the way you like it
6-Make a new backup with TWRP.

If something goes wrong or you don't like rom, boot back into TWRP and restore stock backup.
