Default root for d80020k??

so I took the OTA update for KK and it trashed my device so I ended up sending it to LG and they repaired it and sent it back to me with D80020k preloaded. is there anyway to root this now? I've been looking but haven't found it anything as of yet...

Thanks in advance for the help...


edit: found this... has anyone done this method? http://www.andromods.com/root-unlock...ta-update.html


edit2: Never mind I think I have figured out what needs to be done.. after bricking this with the OTA this is probably the first phone I am nervious about tinking with it..
