I downloaded Froyo for my HTC Desire (unlocked) & it didn't install correctly & now nothing will work on it. No phone signal, WiFi, nothing. When I turn it on, some features will work & some won't, & after around 10 minutes it automatically will reset itself. It says I have 2.2 installed in the Software Information, & I do see some new things, so I guess it's partly installed. The main problem is that I can't do a factory reset on the phone, so I have no idea how else to reboot & re-install 2.2. Any help would be greatly appreciated.
