Galaxy Note 4 N910a OC6- Baseband and IMEI Unknown, Bootloop After *#9090# - AT&T Samsung Galaxy Note 4

I have Note 4 N910A at&t 5.0.1 N910AUCU2COC6 now has boot loop problem after pressing *#9090#. with this new 5.0.1 you cannot downgrade so I've already flashed the same version files passed OK but still has this problem. I think phone might have lost baseband now. Any solution to repair this problem, please help. Thanks :crying::crying::crying:
.

You gotta get a new phone. I went through the same problem.

I have this problem too after updated my Note 2 GT-N7100 firmware to pre-release 4.3. After updated, I notice the baseband and imei is unknown. But it randomly will back to normal with baseband and imei (same like behind battery) and working fine. Sometime I just need to wait for 1 hour for the baseband back to normal. This mean your efs folder still there. Just backup the folder use es file explorer and sync it to Dropbox.
Cheers!
Flash the latest modem. Mj5 mj2 or mi6. Either of those 3 4.3 modems will fix the issue.

Try flashing a patched modem and patched kernel, you can find boths on a specific thread on general section.

Without answering my question precisely I can't help, sorry.
Bootloader is NI1? please check
Which firmware did you flash exactly?
Which exact recovery do you use?

Why do you want to flash an older firmware? It seems to be a KitKat to KitKat downgrade that may work but without guarantee. Nevertheless: I would really like to know your actual bootloader version, check with this app -> LINK

Either you go for NI1 again or try to upgrade to NL1 firmware through Odin. Forget that old ND3.
