Did you try a factory reset via the Android Recovery Menu (you'd have held down a physical switch if so) or via Android's settings menu?
To check which device you have, check
https://droidbox.co.uk/choose-your-droidbox.html . Before continuing, please make sure you defintely have a
DroidBOX device. We do sometimes get visitors who purchased a Droibox (no second D) or other Android device, and I'd not want to give bad advice if your model doesn't behave in the same way as ours. Check your Amazon or eBay records for the purchase. If xbmcgadgetshub is the listed seller, you have a DroidBOX device, similarly, if you purchased from us directly, via our website, continue with the steps outlined below. If you're in any doubt, let us know your purchase details first.
Once you know which DroidBOX device you have, visit this blog post to see where your reset switch is -
How To Access Your DroidBOX's Recovery Menu. Follow the steps there, and when you see the recovery menu, select Wipe data/Factory reset, and confirm you're certain. Once it has completed, reboot, go through any set up screens presented, then once you're at the launcher's homescreen, please don't click on anything or reboot for 20 minutes.
At this point, you'll have a DroidBOX device that behaves as though you've just purchased it. Open XBMC and run the DroidBOX Wizard. One thing to note, with the latest updates from the DroidBOX Wizard, please DO NOT EXIT XBMC after the device-specific pack has been downloaded, extracted and installed. Instead, remove the power lead from your DroidBOX device, wait a moment, then boot up again.
