hi, i'd love to ask for some help here.
my problem is i rooted my milestone for 3 months approximately, it seemed to work great at the first place. but it started to have a problem that it can't read SD card anymore. i did try to format the card and try to put the new one. my milestone still couldn't read them anyway. i want to bring milestone to the service because it's still in the warranty time but i can't (they said that the rooted phone is no longer in warranty) and i can't unroot the phone also dueto the SD card problem. so please tell me how to unroot milestone to the original rom with no SD card. )
