Need HSG X6 Tablet Firmware

[Nyame]

Hi, i need some stable and oficial firmware for my HSG X6 Tablet with Telechip 8902 800MHZ. Mine came with Android 2.3 but i lost it after installing CM7 (forgot to backup)and i want to go back to that version or another good one.

Searched a lot in the web but all links are broken. Anyone knows were can i find the firmware?

Thanks
