I purchased a rooted Thrive. It had some "BakedTeam" Rom and other things on it. One of my associates said that it was hacked and was going to remove the Baked.ROM from it and reset it to factory default. Well let's just say that didn't happen. Now all we are able to access is a TWRP (Team Win Recovery Project) v2.4.1.0 screen. And whenever we try to click one of the restore or reboot buttons, it reads, "NO OS Installed! Are you sure you wish to reboot?" Initially we didn't reboot, but after pointlessly twittling our fingers, we tried it and it went to the "Toshiba" screen and did nothing more. We read somewhere that if we hold the Up volume button while powering it on it will reset it. That didn't work either. Can someone please help me? Is it possible to download the Android OS to my SD card and restore it from there?
