Then
-Exynos reset efs
-Wirte cert over uart, repeat until phone autorestar.
- Repair DRK over UART.

Try writing NV Data and or SEC from backup, or backing up cert, even if phone says 000 NG, might be able to get a valid cert from it

If you don’t save the cert the only way is to buy repair cert based on your cpid.
