Lost root on LG AS855 due to OEM update I lost root privileges on my LG AS855 when I updated it. I used SuperOneClick to root it. Now, it just hangs on step 7. 

This is not a very popular phone and information on rooting it is extremely sparce on the internet. Any suggestions on how to go about getting root privileges back would be much appreciated.
The OEM update will have caused by you are to lose root due to the fact that stock ROM's aren't rooted.

This update will have most likely blocked the use of simple rootkit exploits, which is how all of the one click root solutions work.

It your OEM upgrade was to ICS, then Google blocked rootkits in version 4.0 onwards. If it was not an upgrade to ICS or later, then OEM has patched the OS for all of the common exploits.

If this is the case, then the only way to root you device would be to do we fastboot to flash a rooted boot.img file, or the old firmware so you can use a one click here root solution again.

It is generally recommended that once you have rooted, you don't use OEM updates for this reason.
