The backdoor is probably inactive anyway. Xam is busy stealing money and
, he wont even care about a 5.6
Simply delete error.php and everything will be fine.
The backdoor was not hidden. Wasnt even obfuscated. If you opened error.php and view the code it was pretty damn obvious from the beginning.
I will disagree with you x360zone!
TSSE 5.6 is a great source, but because it is nulled it is not easy for everyone to use.
A newbie should NOT start with this source.
