***UPDATE: Go into Android Market and update the ROM manager to the latest version. It will fix this problem so you can update straight from 3.0.0.5 to 3.0.0.8.
So I recently went to backup using the ROM Manager on my phone. It notified me that there was a new version of ClockworkMod, and I was currently on 3.0.0.5, and should update to 3.0.0.8. So I update, and when I reboot into recovery nothing happens. It stays frozen at the HTC Incredible boot screen.
Luckily, you can still boot into Android.
Here’s the fix.
Go into ROM Manager and flash 3.0.0.6, one version up.
After it flashes, boot into the recovery and select “Clear cache partition.”
Then, reboot into Android. Open ROM Manager, and flash 3.0.0.7.
Boot into recovery, clear cache, reboot, and continue doing this until you are finally at 3.0.0.8. It should boot into recovery just fine. Enjoy!
