Same problem like your but I manage to fix it by write backup NV, then write EFS backup

Use other tool to

1 bypass knox
2 then write modem from combination with that rollback
3 finally use c3300k cable via UART and do IMEICERT_WRITE.

The name of the tool you should figure it out by yourself. Rest of sure you will solve your problem. Hope it helps.
