[Afm]

Hi , I am new to this forum.The only forum I found which provide a dedicated thread on tvbox.

Previously having a cheap tvbox just for basic entertainment E-TV box which looks like below.It get deliver with a custom flash rom which it doesn't work as android UI and more towards media player UI.

I plan to to flash with stock 2.2 froyo or 2.3 Gingerbread but I can't seem to find the firmware and instruction to flash it back

Here , I quota the Android Tvbox specification.I really hope someone would lend a helping hand finding this specific tvbox firmware.
