Hey all, so I tried the instructions in this thread to the best of my abilities and somehow I've ended up back with Android 2.2 and seemingly no ability to get back to a rooted 2.3.4. At one point during the process, I was able to get the HBOOT screen to show "UNLOCKED" but somehow that's been reversed and now I'm back to being LOCKED again and un-rooted. I should mention that none of the steps along the way worked perfectly for me -- unrevoked never ran smoothly and so I was doing a lot of the alternate steps along the way. The last step I ran was unrevoked forever and it failed (the "NAND flash" error message -- I didn't understand the solutions offered when I did a search for this error message). So my question is this: if I'm now back at Android 2.2, apparently un-roooted again, and LOCKED status, do I have any hope of getting my device back to 2.3.4? My only intention in doing all this was to hopefully revert back to a version of Gingerbread that existed before the last OTA update (the one within the past 1-2 weeks), which screwed up a lot of my settings and completely ate up my battery for no apparent reason. My phone was working perfectly fine before this "update". I figured rooting was the only way to get the phone back to stability until I was ready to purchase a new device. Thanks for any advice.
PS: I should mention that, despite being fearless and a good instruction-follower, I'm not inherently familiar with the shortcuts or methods used in these instructions. So answers such as "just run HBOOT and flash a new image" are totally confusing to me -- layman's language would be much appreciated!
