Had S-Off, 2.15 radio, and Skyraider running. Went to Unroot Dan's Worthless Blog and did the HAVE updated radio, and USED forever. I checked the phone settings, and I am back to 2.1-update1 baseband 1.00.03.04.06 and I still have S-Off. The problem is I can not get my 3G to turn on, it keeps trying and trying. So I figured I would try and change the phone back to S-ON, but when ever I get into recovery I get the "warning" symbol (red exclamation in a triangle showing the phone) and I have to pull the battery. Anyone know what is up? Do I need to re-root to turn S-On, then unroot again? Any help is welcome.
