i have a nook hd and nook hd+
i installed cm10 on both systems using the permanent sd card method
the nook hd is used by my five year old and i heard her saying i am going to wipe minecraft
didnt think anything of it and tonight i powered up the nook and it has gone back to completely stock firmware
would the erase and wipe from the menu return it to stock even though cm was installed?
was i very lucky ? i didnt have a back up of the nook hd but i do have a back up of the hd+
