Do you know if it's a DISCO or DISCO 10 model. It could make a difference.
If you do have a DISCO or DISCO 10 you can download a new Tims rom at Flytouch 3 Hybrid ROM (rooted)
or funnycomb at FlanFlingers FunnyComb Beta
funnycomb is a bit more smoother than Tims Rom but both work better than the stock rom on superpad or flytouch.
