Hi, I'm coming from an epic 4g touch (Sprint s2) and trying to figure out how to flash a friend's att s2. He already has a custom gingerbread ROM on there, but wants to upgrade to cm10. Since I know it's fairly easy to brick if flashing the wrong ROM, can someone give me a quick rundown of what's needed to upgrade? I'm not familiar with hellraiser or any other terms specific to this phone, but I've used odin many times. If you can point me to a ROM with cwm that I can odin, then go to cm10, that'd be appreciated. Thanks
