So after installing deblet and android, and loads of other stuff, I want to have a cleanup of my n810 - specifically wipe it and start again.

Problem is, when I try and put the tablet into flashing mode ( power and swap key method ) the Nokia logo appears with the USB logo, then immediately I get the message to hold down the menu key for the advanced boot menu. At this point the USB logo disappears. The result of all this is that I can't get the device recognised by the flashing scripts or the windows software updater.

How do I remove the bootmenu so I can do a full reflash of diablo please?
