HELP! Can't get out of MeanBean! (boot loop)

view story

http://forum.xda-developers.com – I've been running Mean Bean since March, since it's not updated anymore and I'm looking for something new, I figured I'd try and install another ROM. Any other ROM I try and install it puts me into a boot loop. I can go into recovery and reflash Mean Bean and all is well in the world. But nothing else! What am I doing wrong? I am S-on (I know, I know...). *update - now I am stuck at the Mean Bean splash screen (HowTos)
