Hey, I have a DI rooted running 2.1 but it has the updated radio because I had previously installed the leaked OTA 2.2 update, but reverted back to 2.1. I need to go back to completely stock/shipped from factory state as i've been having issues; tried following your walkthrough and I just have no idea what I'm doing. What files do I need to download, where do I put them, do I have to have the phone connected via USB or not? Where do I type all those adb commands, on the phone itself when in clockwork recovery, or in the cmd prompt in windows? If you could write back and help me out I'd really appreciate it, thanks.
