Now I have actually gone that route as well. I went and disabled S2U2 in the registry like I posted awhile back. Well for some reason that doesnt totally disable it. For some reason when calls came in the slide2answer still popped up and froze things up. So I think its safe to say we prolly wont find the exact answer to this issue. BUT, what we do know is a few hard resets sometimes solve these issues. Maybe thats what helped me. I've done a hard reset several times till I had gotten things working. Some might not know this but the first hard reset doesnt always solve your problems It sometimes takes a few to clear things up.
Also, I'm not sure if everyone knows this but after you flash your phone its good to take out your battery for at least 30 seconds as soon as your flash is done. This is for the pagepool to reset. Then when thats done and your phone is booting up and your phone gets to the welcome screen where you set your time and date you should do a hard reset. Every single time I've done this process my newly flashed rom works properly.
Sorry, just more thoughts. I'm sure people prolly already know this but it cant hurt to post it to double check
