Thank you for the tip phoneyericsson!
I didn't find it hard to do -- I pulled off the ruber thing with a nail, and tweaked out the plug with some small scissors.
I was stuck at the SE logo, and couldn't turn of my phone or enter CWR. I wanted to set it back to standard using SEUS. Instead of using the method mentioned in option 2 here
, I simply pulled the white plug to the battery, which turned of the phone. Then I inserted it again and the phone stayed off. Then I simply did as SEUS asked, and now I'm back running, ready to get CMmini on my device again!
