I am now using mikg2.5 amd golden monkey. All seems to be fine and ive done a nandroid before every change. 1 does the nandroid also back up the current kernel im using and if i restore back to my original gingerbread rom will the kernel also be replaced. 2 if i decide to install set cpu will the nandroid also back up all the settings and the app. 3 is this right for batt calibration Plug in after flashing wait for full charge turn off phone turn back on . then check usage and time up should be the same.
