This thread is for those of you who have the lg G flex, you were on android 4.4.2, got the news of the updated Freedom Flex with bump, installed twrp or cwm recovery with Freedom flex, then tried to flash an unofficial cm11, or other custom rom zip and the zip fails to install because those old roms are not updated with bump yet I think. And if for whatever reason you did not make a backup (easy mistake, I forgot to make a backup which is why I had to go this route) this is for you. Anyways, I spent many hours before finally being able to bring my g flex back to life, and I'm hoping this thread can help you to get your g flex back up and running in much less time than I spent finding this solution.
Prerequisites:
1. You need to have an LG G flex that has either CWM recovery or TWRP recovery still working. If you have a custom recovery installed, you can get into it when the phone is off by pressing the volume down and power button together and holding, as soon as you see the LG logo, release the volume down and power buttons and press and hold them again. It will take you to a factory reset screen. If you have a custom recovery installed, you can choose yes, and then yes again, and it will not factory reset your phone but put you into recovery. If you have the stock recovery it will wipe your phone so be careful.
2. You need to have adb installed on your computer. On windows, you will also need to have the lg drivers installed on your computer, on linux this is not necessary.
Final Result:
You will have cm11 installed on your phone, sound doesn't work but cell signal and data do. So this is not a complete solution, but at least your phone will be mostly working.

Alright Here goes:
1. Download mattwheats version of cm11 here to your computer https://docs.google.com/file/d/0B2OabWtEBQcpdXhkRWIxNlFZSWM/edit
2. Boot into cwm/twrp recovery and perform a factory reset (this will wipe out your apps, but you should still have your files, photos, music, etc. intact).
3. connect your phone to your computer
3. Open a command prompt / Linux terminal and type "adb devices". You should see your device listed as "device" or "recovery" or something like that. If you don't see your device listed, you either don't have adb or the lg drivers installed properly. Refer to other tutorials to figure that out, they are out there.
4. Once you verify that your device is connected through adb, use the cd command in the command prompt/terminal to navigate to the directory where you downloaded mattwheats cm11 (example: "cd C:/Users/yourname/Downloads").
5. (not required) rename the cm11 you downloaded to just cm11.zip. Just makes it easier to type in later
6. Type the following command into the terminal "adb push cm11.zip /sdcard/" you will see a blinking bar for about 30 seconds, after which it will say it pushed xxx bytes in 30 seconds. once you see that, the cm11.zip is on your device
7. In recovery choose install zip/install, navigate to /sdcard/ and you will see the cm11.zip there.
8. select the cm11.zip to flash it.
9. confirm the flash
10. reboot
At this point your phone will boot into cyanogenmod! If the pixels on your screen go all crazy and turn really bright/different colors everywhere, just press and hold your power button for 10 seconds and power your phone on again. If you see the blue cyanogenmod head and the arrow circling around it you are in good shape, it will take a little bit to boot but will boot into cyanogenmod.
Success! Well your phone mostly works now...shouldn't be too difficult to get it fixed the rest of the way from this point, or you can just use cyanogenmod if you don't care about sound, some other stuff might not work as well. Hope this helped somebody.
If you want play store and whatnot, just search for 4.4.4 gapps zip on google and download that and flash it in recovery. That will give you the basic google apps.
