Hi guys, for a forensic project I need to access secure hidden partition from a flash with this controller. Did you have a solution for it now? Can you help to try to patch it or create a custom firmware? Do you think I can send the special unlock command thru usb or I will need the password as well, therefore only patching will work? Thanks for your answer.

I see some body say after firmware sail killed flash. I say no before insert to PC hold nand chip 29+30 with one piece as wire hold for 3second and let it In hardware boot mode you must hold 2 pin io
