hello, from the log of z3x you wrote it appears that you have damaged phone security.

If you have the unknown baseband of the phone you can try to write other firmware of the same binary 2 of the phone and see if the baseband returns correct, in case it does not resolve with the firmware flash you have the security damaged, you have to reset the efs with z3x and then write the nv file if everything works then write the cert or do the patch cert.

In case you need the efs for n920l you can download it here

unfortunately for nv_data file for n920L you find it only for a fee at least that you don't have another similar model and I read it with z3x
