Locked trojan SAS (Advance RAT)[Android][Windows] + Setup Tutorial

[h19server]

downloaded this version :    

did everything according to the instructions, and i was able to login, but i got 2 few problems: 

1 : after changing the default password i was not able to login again with the new pass also with the default pass, so i had to delete the server.php form the server and re-upload it again to login with the default pass but with no default pass change

2 : after getting some targets the TCP option is disabled at all and not working,  is only the  HTTP / IRC work for me.

is the any solutions to resolve these 2 problems for how can i change the default pass without any pro and the functionality of the TCP to be active and usable ???
