The best option.
well i tried to root my optimus s (ls670) with gingerbreak--- it said it worked but really didnt. then downgraded to zvd software and then superoneclicked it and it said it worked and when i went to upgrade the binary on superuser it told me that my binary was "legacy" and that no binary was found and so it stopped the update. does anyone have any idea what to do with this dinosaur of a phone??? PLEASE HELP with LINKS both for instructions and ROMs/kernels/recoveries------------ SPRINT LG OPTIMUS S (model ls670)

I cannot go into too much detail since I spent hours on it and forgot and renamed a lot of stuff.

Hey, so I just got an LS670 (LG Optimus S) from a friend to replace my current phone. Not sure how it will go since I have an old SERO account.
Anyways, I had some time off and would recommend to you update flashing your baseband to ZVH. Turn on usb debugging from the applications/development from settings and use stay awake option.Use Sons Of Korhal 1.0.1 to root it. Update to ZVJ using its appropriate update.zip. Then use OptiAuto (aka OptiAuto-sfx) if its the new enough version will allow you to root the zvj baseband. Some of these files are hard to find, took me 3 hours total in trial and error.
