Help with Kobo N647B

[BillyJoel]

Hello,

I recently bought a kobo n647b. In the process of trying to figure out how to get it working; I uploaded the wrong sytem update (Kobo Glo). Previously it worked fine, now the screen just flashes on and off and there is no response.

I tried a disc image, factory reset, and varous combinations of holding the on/off button. Nothing happens.

Is there anything I can do to get it working again?

Thanks,
Billy
