I rooted my phone awhile back using the Sapphire method. When the 2.2 update came out I tried to unroot but failed @ getting it to work right. My phone still worked so I just left it as is. Flash forward to today and my phone is jacked up. I installed a update.zip file that is suppose to unroot my phone but it will not allow it to install it just says install aborted. Now my phone will not make a call or do anything but foreclose whenever I click on any settings. Please help I think I got in over my head. Also when watching the video for unrooting his recovery looked different then mine. Mine goes to ClockWorkMod Recovery which has different options.
