I have SPRecovery 99.2b, running UltimateDroid 10. I'd like to get back to a stock rooted 2.1 ROM. What's the easiest way to do that? Seems like I saw there was a rooted stock 2.1 update.zip out there I could flash with SPRecovery, but I can't seem to find it. Also, do I need to update SPRecovery, or is 2b ok to use? Thanks!
