Ok, I know the title is a little vague but.... I used to be rooted running UD and now i went back to stock with a modified update.zip that removed SPrecovery, wiped data, and did a factory reset. I installed the OTA 2.1 update, but now the problem is that while looking through androzip (clicked back once to leave sd card) i see a folder titled "root".... is this suppose to be here? thanks for the help!!!!
