Hello,

Taking install the google play my tablet is no longer usable. Ie it crashes at startup on the logo text "Android".
Seeking information on the internet, I saw that it was possible to reinstall the tablet from a backup.
Having multiple tablet MP1000, I made a backup of the system to reinstall the problem.
But not to access fastboot mode.

Could you tell me how to access this menu.


Thank you in advance.
