They make this revert sound complicated and its so easy. I done the update that stoped the free tether via quick settings app so this is the easy fix. Ignore the non working screen warning because that was a bunch of crap for me. First plug youf phone in and download the phone drivers. Then download LS670zv9_20.s9_20.p60671.cab when download is complete just right click the .cab file and rename the file LS670ZV9.cab next download lg mobile update tools. Next download kp500.zip file and extract it. In the extracted kp500 folder place your LS670zv9.cab folder in there. Now inside your kp500 folder you will see your kp500 application in there. Start kp500. It will look like command prompt. Type j then hit enter it will ask for model number type LS670 and hit enter then it will ask for the name of the cab file type LS670zv9_20 it will open up lg mobile tool and the update will begin. It will change the android version from software 2.2.2 to 2.2.1 and it wont loose root or any apps at all thats bull. Dont back up you dont need too. Read the head ach up above or do it this way.

The warning is there because some phones have the new LCD. Just because your phone doesn't have the new LCD doesn't mean it is good policy to hide an obviously negative and disconcerting behavior from other users.
Nowhere in the warning on the LCD does it say all phones are affected so it is unclear why you are saying it is a bunch of crap.
first off, when choosing wich carrier/country/phone model number to instal usb drivers from lg tool mine is not listed.. i am using optimus s. i am lost... if there is a post for dummies or an easy fix, please by all means point me in the right direction. ty
Look at the sticky posts. Read up a little bit. Then give it a go.
EDIT: also with the carrier, country thing you just need the model number of your phone. It won't be listed a optimus s. But I can tell you that all the info needed is in these threads because I rooted my phone when they first came out and these are the guides I followed. so the info is there, it just may take a little reading. Or use one-click root.
