Hi,
It's really easy.
Go to Snake X's [Root][Recovery]Ultimate warp drive!
Download one file there - utimate warp drive.rar
Download 7zip to unpack the rar (rar is like dumb zip) -
7-Zip
Everything will unpack into a folder named, ultimate warp drive.
Inside that folder, you will see a file called "- RUN ME - root + cwm + stock.bat"
On your phone go to settings, then applications, then development, then check USB debugging.
Also, under applications, check UNKNOWN SOURCES.
Plug in your phone.
Run that .bat file (get a dos window, go there, type in the name, or just double-click it, I forget the best way on windows - probably double click will work).
Choose option 1 - wait patiently and don't tinker with anything.
When it's done, you have full root with CWM installed.
I was wrong about one thing - remember I said that root was achieved by finding a security hole to exploit, CWM is installed last?
CWM is part of the security exploit here.
Snake X modified his post on June 4, so his stuff there is up to date.
Ignore the "stock_XXX_rom_signed.zip" files completely.
