Why all these usefull Steps like "Wipe EFS"? like DRK repair, other Programs running ADB like Kies or Other Box open itc...

Just Click in "Reset MSL" and Write Cert.

Now write Back "first Security Bkp", since haven't BKP the Most important thing "Original EFS", then try to "Reset Msl" and write Cert.

Always Read carefully "HELP Button" in sw first of press any other usefull button, and do ALL BKP of EFS, Security Area itc..

Please try to do the next:
1. Write First Security backup back into the phone.
2. Remove SIM card from the phone.
3. Repeat "Write Cert" operation.

If problem will remain the same, do the next:
1. Write First Security backup back into the phone.
2. Make Factory Reset and Reflash the phone.
3. Root the phone with CF Auto Root.
4. Repeat "Write Cert" operation.

Post here result and full Software log of performed operations.
