RE: Factory Reset China Tablet (Not enough options)
Basically, device ROMs has two parts: Recovery part and ROM part. Recovery part is kind of BIOS on your PC (this is not completely true, but I needed to give an example). It handles loading your phones OS, flash, reset, etc... functions. It is possible to only flash Recovery part of your ROM. But, you need to find a Recovery ROM image that fits your phone and you must know how to do it.
