I was also stuck there but when i flash the gapps for ics it started. I hope it'll help you.Hi,
Today I attempted to upgrade my HTC legend from CM9.0 Beta2 to CM 9.1 Beta5 using Rom Manager. I selected wipe davlik cache. Everything looked ok during the process but when it rebooted it is stuck on HTC logo and goes no further.
When attempting to go into recovery, after selecting recovery, it goes to the red triangle with ! mark and is stuck.
How can I get out of this mess? It's been a while since I messed with an HTC
