Well I have root explorer, and when I go to my bin and xbin, I don't have an su file, and I tried putting it there manually but it said the phone is 'read-only' I'm so lost, how do I put my phone in stock mode, please help me, I really want 2.2
you all are making this to hard.
simple way, connect your phone to computer, pull down the notifications bar on phone, touch the USB connection notification, choose pc mode, then open windows explorer on your computer, copy the update.zip to your main phone directory, then follow the install instructions. you dont need root, or any other programs...
