I tried to downgrade (which seemed fine) - then install the radio update, now it's locked on the droid image with the red exclamation point! Nothing is responding. Holding power button does nothing. I know taking the battery out is a big mistake, AM i SCREWED??? Edit: I was able to get to recovery screen - it took much longer than expected. Installing radio update now. Finger crossed. This is scary. Update: It worked! I'd delete this thread if I could, but I'm sure some other noob will panic during this part... so I'll leave it and they can see that they're not screwed if there is no response for a long time with the red [!] before getting to the blue recover menu.
