How can re factory reset my grandson's tablet.  He's forgotten the pattern.  Holding volume up and power only brings up a fast boot mode msg and nothing else.  We were expecting a menu.

    have you tried volume down + power button?

    Yes, unfortunately.  Have tried several different combinations.  Power and vol up produces the fast boot mode msg - anything else just turns the table on.

    from fastboot you can wipe your tablet to factory but you need to be a little brave and have a PC.

     

    1. download light ADB enviroment and install it: http://forum.xda-developers.com/showthread.php?t=2317790
    2. once installed, with your tablet on fastboot, connect it to your PC and wait until it installs the fastboot drivers
    3. once done, start the adb enviroment and then type

    fastboot devices

    fastboot erase userdata
    fastboot erase cache
    fastboot reboot

     

    this will reboot your device normally and if it worked, it will start from the classic first time boot android UI

    Thanks for your advice, Ironfly.

     

    I downloaded the app and joined the tablet to my pc and was then expecting bells and whistles but it just sat there.

    So, fastboot commands didn't work?
