Where i can find my stock rom Recently I bought a Chinese made android phone. Specifications of the phone is given here. The phone has mediatek mtk6577 processor. I been thinking to install different ROM in my device. But, I can not find source to download this ROM. Is it possible to install google stock rom in this phone and where can I find this rom? How do I know which rom is compatible with my device?
For finding other ROMs, Google is your best friend. If you can't find anything with Google, chances are that there aren't any custom ROMs for the phone. Any ROM that is compatible with the device will specifically list the phone. If it is not listed, it is not safe to flash the ROM and may result in hard-bricking the phone forever.

As far as the stock ROM goes, Google is again your best friend. Many manufactures post the stock ROM on their website for just this reason, however, if it is not there, you can always take a nandroid backup of the phone which also captures the stock ROM, allowing you to flash back the stock ROM if you wish to do so.
