My problem that no longer exist
I have the exact same problem as the OP except for one more... I do not have a nandroid backup. I've been busting my ass of on google, and I'm not quite sure of what I'm looking for. It's a bit of a mess with versionnumbers and such. I happend right after i reflashed my HTC with Revolution from Cyanogenmod 11. I entered blindly into the Team Win recovery, and deleted the internal storage. This did not seem to work, and i was stuck inside the splashscreen, I then used the same method as OP to get back into recovery, and followed a guide where i wiped system data, cache (i think), and dalvik cache. This seemed to work (with the Revolution ROM) untill i used Titanium Backup to backup my apps, and restarted. This got be back into the splashscreen. I've then tried to reflash Revolution, but to no luck. I'm still stuck in splash.
I would very much appriciate if someone could help me out here!
