Factory reset a device - settings app does not work How can I factory reset my Arnova GBOOK tablet/e-reader?

It runs android, and now everything force closes when the device boots, inluding the settings and launcher applications.

I need to use my device - I only bought it today.

Please can someone tell me how I can get my device back? I think resetting may help...

So - how do I reset without the settings app???
I can't find the factory-reset instructions for a device with this specific name. Arnova's devices are named in confusing ways, so perhaps several names are used for the same device in different markets. But can you find a pinhole somewhere at the botton of your device? It should be on the left. Does it say "reset"? Then insert a paperclip and see what happens.

If that doesn't work, you could try the instructions on Arnova's support page:


  "If your tablet freezes often or if you get error messages during the start up of your tablet, you can use the recovery mode to reset your tablet to its factory settings, removing all installed applications as well as any data or content.
  
  Your tablet must be up to date with the latest firmware – downloadable from the downloads area of this website.
