You'll need to flash Nvram file to fix this. Do you have a backup? You can also search online

Can you confirm that Baseband and IMEI are valid?
Are you still on Engineer firmware or back to original?

You'll encounter NV Data issue when you write both IMEIs. You either fix the non-RSA protected IMEI slot only or you use a paid tool to write both IMEIs.
Backup Nvram and Nvdata then erase both. This should take you back to square one from where you can confirm its back to the way it was
