Samsung g920t Security Damaged. Unable to Unlock

As the title says...
It all began when I tried to unlock my phone through Octoplus, direct unlock, I was able to save the EFS and the Security backup with this same tool... the Cert was never able to backup.
Turns out that Octoplus damaged my security when I unlocked it and the backup is corrupt. I restore everything back (security and EFS) and got my IMEI back but when i use my Z3X it says that my security is damaged... so is there a way to get it back? I cant downgrade cause im on the latest T-Mobile firmware. I tried flashing different Certs with no success...
