Hi All, I was upgrading by refering to this post but got some error. Then I tried burning the ROM that I had previously burned but that failed too. During these failures all I could see is screen like below in white color with black background. ----------- DOWNLOAD ----------- And then I screwed up by taking the battery off. Now I am not being able to turn on the phone. I tried hard reset (vol up + home + search) but didn't work. Please help. How do I power on the device so that the host detects it so that I burn something.
