If this helps any, I erased recovery folder in the file I downloaded. I had to resort to a nandroid backup because I had an battery indicator mod. Also had to flash 4.0.4 stock kernel and xxla2 radio. Took me about 3 hours to figure it out. The battery mod is what got me and I didn't know how to pull it. Another reason backing up is a good idea. I have everything I need to preserve important stuff so if I had to go completely stock I would've been good regardless. Nonetheless, having a 10 day old nandroid saved me a lot of trouble. If you can call it that. Also, ota root keeper didn't keep my root. I ended having to flash superuser again, but that was probably my smallest inconvenience. The update seems good so far, my touch input was good before and seems a hair better. Multi touch is outstanding. No radio issues I've noticed but I'll be in good area most of weekend. Keyboard input is even better and faster. Its all good in da hood here.
bow chicka wow wow.
