I'm a newbie here and like if people here can help me. I have a APAD rockchip running on Android 1.5. I recently asked my seller in China to update 3G settings. They sent me few images boot.img kernel.img misc.img recovery.img system.img I tried to ask them which files to update, but the sale person does not know. It is another tech guy that sent to her so she's not sure. Do I update or should I update all images. Any advise? And do I just use RKAndroid to update the images? or is it a better way to update?
