Hi can anyone help, i have a manhatton plaza 3300 with kaon 12.01.a5 firmware which i have always upgraded with when new firm comes out. I have now flashed with the bm-8300ci 12.01.a5 off this forum and i can not get past the menu lock after the stb as rebooted, its a 4 digit pin code i have tried everything suggested on this forum but nothing works and i have read through tons of posts to try and fix it before posting this. As anyone got around this menu lock.
