First you must download files in the url below. It's contains the driver and software for celular root acess (SuperOneClickv1.7-ShortFuse)
I can't post url. However you must search files below.
Or request for me the url them.
Then, unzip the file root_x8.rar in your computer. There will be two files .zip: SuperOneClickv1.7-ShortFuse.zip; X8_drivers.zip. Unzip them.
Then, go in Settings -> Applications -> Development -> Select USB debugging. And select Stay Active.
Plug the USB cable to your computer and your mobile. In the window that appears on the phone, select Load.
The computer will install the drivers, except one (SEMC). Then go to Control Panel -> System -> Device Manager. On Other devices the driver SEMC will be marked as unrecognized. You must update this driver pointing to the folder created by unziping the file (X8_drivers.zip). Wait to finish the process update.
After the driver is updated successfully, open the folder created by unziping the file SuperOneClickv1.7-ShortFuse.zip. Now execute the SuperOneClick.exe.
On the screen that opens, do not change any settings and click on button "Root" and wait for the process. Will appear a screen on the cellphone, tap in "Load" how often it appears.
During the root, will appear some screens. Read with attention what it says and press the button needed.
Done that you will receive a confirmation message that your phone is with root access.
On my mobile phone was made this way. To confirm, go to the market and download the application Root Check.
Thank you all. And good luck.
