Hacking backup launcher disc read error

[Ralle1]

Hi

I used to play galaxy 2 through the neogamma backup launcher.
Then i wanted to play games from a USB drive so I installed a bunch of ios and cios and installed usbloader channel.
But galaxy 2 didnt work with the usbloader so i tried the backup launcher and now I get disc read error.
I get error #002 if I play from disc channel. What should I do?
I have 4.1E cyclowiz chip.
I can play old games from disc channel.
I made a NAND backup and installed 4.2 but that made hbc go away and backups unbootable.
So i restored to 4.1
