[martinasa]

hmm cuz i did fully downgrade and write cert without VOID knox.. and i dont have other phone to test if possible, cuz now the phone take both software and works perfect..

You can downgrade to previous firmware and reset EFS just in case you got "Unknown baseband" to bring back your baseband ... write your cert ... problem solved!

[martinasa]

when downgrade and reset EFS the programs reset DRK but not EFS than you stuck on logo
