Service Menu to change model no !

[erdem_ua]

1. No support for C series yet.
2. Some of B series owners bricked their devices via changing it's model number via Service Menu. But some of them are successful too. I don't know any experience about C series...
So it depends on you.

change model type dosn't enable game mode on B series, simply because firmware dosn't have it.
difficult to say for C series, but it might similiar situation.
