Flash ROM easily
I read in other forum (hasithachat):
To change the ROM, down the ROM and put it as update.zip
to the sd card and use this tool:
chinamobiles.org /downloads /zap / m44mtk.apk
to install the ROM, this is a apk you have to install it on your phone.
And a way to overclock:
Download in play.google
and adjust the slider you can go to maximum 814mhz , but leave it at 790 , if you go over 800 it keeps restarting . The launcher and apps run much much smoother , its almost a 20% boost. Battery is not affected that much.
