So The poster who posted some of the other G Flex files for going back to stock the threads were closed so I could not update it with new links. I have obtained some more KDZ for different models in Europe now :) The KDZ`s are some what hard to get for the G Flex but I was able to get a few extras :)
Below is a Guide that has worked on Flashing the other LG phones it should be the same for the G Flex :)

NOTICE! - IF you download fails or does not download all the way USE A DOWNLOAD MANAGER!, Files that are usually over 1GB browsers have issues downloading them especially if you have a slow connection.
NOT Responsible if you flash the WRONG one

Normal Flash: Flash ROM without losing any data. Only use this when you need to fix system error. Beware of boot loop when flashing ROM that differ from current ROM on your phone or MOD ROM.
CSE Flash: Choose this option when you need a fresh format. All data will be gone. It's suitable for upgrading or downgrading ROM or simply use this when you need to back to Stock.

Great guide OP!
I have an F340L, what if I flash the D955 common for Europe, is it possible? Would I be able to receive OTA updates? Would it be safe for the device.
I'm from Greece, I think this would answer questions for many European members owning the Korean variants.
Thank you!

    WARNING!!!

    WARNING!!! DO NOT PAY to download TOT`s or KDZ files! Not sure if anyone here has before, but I found a link for the latest V10I AT&T TOT and I clicked request permission and I was greeted with an email from someone asking "Who is this" followed by another emailing me to send $30 to there paypal account for the link. So NEVER pay for any files. These files at one point will be available on my server and other places. So just a warning to save you time and money don`t fall for these idiots.
