ive checked with mtkflash and it seems its aint got mediatek chip
a few months i downloaded the 1.0d firmware that came with 3 files


if ill find a fast firmware with that WinInst.exe will it work?
or if you have the same cd-rw and succesfully overclocked it to a fast cd-rw let me know what you used
