You need to do a hard reset which will wipe all data and restore the tablet to factory settings.

Is it going through a hub/switch. If so, try direct connect.

Can you tell me where you got the upgraded rom from, and have you tried downloading the firmware from the manufacturer's website? http://www.archos.com/us/support/support_tech/updates_fwm.html

I have similar problem, my buttons on the right side including yjr start button have slipped inside the case and I can not restart the charged device, Can you help?

i cant ulock tablet forgot password please can you help

A bit late but FWIW, I had this problem. I eventually just moved any data I needed to a safe place & fully reset it.
To reset, hold the power button & volume up button simultaneously. It should boot to a screen that tells you what to do next. I think they ask you to keep holding the power button for a reset. Do that & you'll see a big old 3D Android figure & a blue progress bar. Give it a minute & it should eventually load. After that I got a screen that said it was "updating" & gave me a percentage countdown. It finally booted like normal to factory settings. All of my data was gone but it now turns on/off like it should.

a new screen would cost around 50$

The reset button should be on the top of the tablet and it should be silk screend on the back of the tablet as reset

it has a fault bring it back
