1.i did a root by using the sprint cl updater14 which you can get from sprint.com/downloads go to samsung moment click details and download. 2.Next you will need drivers for the download process you can google samsung mobile v5 drivers. im using vista its the only os i tried from windows 7 and xp that let me root with no problem. 3. you also need the de03 recovery .tar file.
install but dont run the sw upgrader from sprint after which u finish installing it will restart your computer. go into c:drive/swupgrade/models/binary and place the recovery file in that folder( make sure no other folder is in there).
download drivers first, run swupgrade, follow instructions accurately. to root all you have to do from here is choose a kernal you want to use first, then plug ur phone up to the pc make sure ur able to get into the sd card if not go into settings, applications and make sure to uncheck debugging. now u should see the usb connection check mount. place the zip kernal on the root of your sd card unplug your phone go into recovery mode (vol dwn, end, and talk buttons) hold em to u see the boot screen. use the vol dwn button ao select apply to zip (zip kernal you decide to download will show) use the black button too select and follow the instructions. some kernals come with the wireless tether already on it.
