I rooted my phone with Unrevoked 1 and then Unrevoked 2. Recently I had a problem with my phone and hard reset it. I tried to reinstall unrevoked 1 to get my super user permissions back but it didn’t work. My question is how do I get the super user permissions back so I can WIFI tether. Can I just flash the stock Rom that shipped with the phone or do I need to find an updated/ rooted stock Rom? When I did the Unrevoked 2 hack i used his hacked OTA update. I never downloaded the sprint one. I believe that the unrevoked 2 hack gave me the ability to flash Roms. Please help with this if you can. I’m really not too familiar with android and need to get my root back. Thanks.
