I want to update my Sony Ericsson Xperia X8 from Android v1.6 to Android v2.1. I have been researching online for hours how to upgrade to 2.1. I used SuperOneClick to "root" my phone. However, although I did get the message "Root Complete!" I don't see any difference except for there is a "Superuser Permissions" icon on my screen amongst my other apps. The icon is a little man dressed in black holding a rifle/gun. I tried downloading "Superuser" application from the Android market, but I kept getting "Installation Unsuccessful." I tried rooting my phone again, using SuperOneClick. But again, I don't see any difference. I followed the directions in the "Root/Unroot - a very detailed explanation" thread. I had debugging enabled. I had my SD card unmounted and removed from the phone. My SI is not in the list of SI codes to which A2.1 is currently available. There were lots of guides online today on how to hack this. However, my root did not appear to work, and also one of the steps in these guides was "Change your SI or Customization Code" - yet I could not find anywhere online which told me how to do this. I'm at a total loss. There is another guide to rooting your X8 here: Alternative rooting method for 2.1 (advanced) - xda-developers However this requires the download of "Superuser" application, and as I already said, this did not download for me. I have no idea how to root my phone. I have only had the phone about two weeks. I am very computer-literate, but I am not familiar with how phones work. Can anybody help please??
