I have a mytouch 3g with the 3.5 mm jack and I had my friend root it to cyanogen mod for the htc magic. The root was successful at first, but after about a week or so, my pictures and music became currupt. So he formatted and started over and all was fine for a while again. After a couple weeks it did the same thing, but now its slow and some of my apps dont work and constantly force-closes. He has since been locked up for things i dont know but I tried to do it myself and it seems there is a problem making the goldcard. so i tried to revert it back to stock and it says that the sappimg.zip is wrong. what do i do to revert it back to 1.6 PLEASE HELP!!!
