Hi, I'm following the below process to root my Optimus One. I'm currently on 2.2.1 and was stuck at this part; "Conect your device (do not turn on disk storage) and run KDZ_FW_UPD.exe (Has administrator)." How do I turn disk storage off? Also is there a more safe, easier way to root this phone? What software do I use to image the current OS? Thanks!
