I could not find a reliable procedure for performing a factory reset / restore on these devices, so I have put one together. The official procedure from Asus did not work for me.

This has been tested specifically with the MeMo Pad 8 Model K011 (ME181C), but it should also work for the MeMo Pad 7 (ME176C).

Here are the steps:

1. Power off the tablet
2. Press and hold the volume up button. While holding it down, press and hold the power button.
3. Release both when you see the Asus logo appear.
4. The tablet should then boot into the Droidboot interface (shown below).
   
5. Scroll down and execute Recovery.
6. The tablet should then reboot into the recovery screen that has the robot tipped over with the message No Command (shown below).
   
7. Now press and hold the volume down key. While still holding it, press and release the volume up key.  You can now release the volume down key.
8. You should then be presented with the Android system recovery options that will allow you to do a factory reset.
9. It takes a while so be patient. Once done simply choose the option for Reboot system now.

After installing this update you may find that you are no longer ble to launch your Start Menu. When clicking on the Windows logo button, it is animated but the Start Menu doesn’t appear.

Try the following:

1. Press Control-Alt-Delete
2. Launch Task Manager
3. Click File-Run New Task
4. Type control panel and press enter
5. Choose User Accounts
6. Click the option for Make changes to my account in PC settings
7. If the window comes up but gets stuck with the gear icon, try right clicking on your Start Menu button a few times
8. When the settings window appears, Choose Sign-in options, located on the left
9. Find the option for Use my sign-in info to automatically finish setting up my device after an update or restart.  Having this option enabled seems to be the root cause of breaking the Start Menu
10. Disable this option then reboot.
    Note: an alternative way of safely rebooting without a working Start Menu is to use the command line. Start a new task cmd using Task Manager in similar fashion like steps 1-4 above. When the command window appears, type the command: shutdown -r and press enter.
