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 18.104.22.168, and should update to 22.214.171.124. 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 126.96.36.199, one version up.
After it flashes, boot into the recovery and select “Clear cache partition.”
Then, reboot into Android. Open ROM Manager, and flash 188.8.131.52.
Boot into recovery, clear cache, reboot, and continue doing this until you are finally at 184.108.40.206. It should boot into recovery just fine. Enjoy!
