N9005 Error while attempting Wipe security/Write Cert, QCN


Hi All, I’m in trouble with a Galaxy N9005

I performed the reading of Security and EFS correctly.

But when I try any of these option I get an error:

  • Repair/Wipe Security
  • Read/Write QCN or Cert

I just performed a full (double) reflash of stock rom 4.4.2 but I cannot manage these errors in any way.
What can I try?

Thanks in advance.
