Almost bricked my Android today. Accidentally closed out of the app that was updating the phone (it wasn’t working as it was, from what I can tell) while trying to get FroYo, and it wouldn’t start back up. Luckily, I was able to recover the damned thing and now have Android 2.2 on my Captivate.
Lost everything though. No big deal, I’ll reinput all my data when I get home.
