[AT&T LG G2] sobitthen:
AT&T Lge LG-D801

I see Google Play gives us a new device name after the flash.

I could not find any clear tutorial on installing this ROM.

From reading as much as I could on the 5.0 ROMs, some flash twice, some use special kernels, some add other items I never heard of, some say 2-3 reboots, some install just ROM then reboot and install Gapps, some entering recovery and wiping cache after each step, etc..

Coming from a stock LG-G2 D800 this is what I did, I consider myself lucky it worked...

I used the Stump, it was not called brute force but there was a similar term in use that rooted the Y updated oem ROM, then tried the Autorec method, the Autorec asked about fixing SD write options but since this G2 doesn't use an SD card I clicked NO to that request, it had options to reboot into recovery or to exit, I hadn't copied any zips over yet so I exited.

I then installed TWRP manager, but it did not think TWRP was installed and neither the 800 or the 801 are on the supported device list.

I copied over the zip files into my download folder to get that out of the way, CM12 latest nightly, latest full Gapps, and the SU file you mentioned.

Thinking TWRP did not install I loaded CWM manager and installed their recovery from within the app, or so I thought, there was option to reboot into recovery, since I had already moved the CM12-GAPPS-SU zips into the download folder, I chose that option, when it rebooted and entered recovery I was in uncharted waters, I had never used TWRP and there I was on TWRP 2.7.0.0.

I managed to find format Cache and format Dalvik, I did not see any option to clean for new ROM like within Philz that I had been using, so I then flashed the CM12 ROM, added Gapps and SU to a queue and flashed those, then formatted cache and dalvik again and rebooted.

It went through process of updating apps, then upon reboot it asked me which version of my former phones would I like to load my apps from, I chose my former phone that had all my apps and it proceeded to load all the apps that were on my former device, I had just switched to this phone 3 days ago. All seemed well until I ran Facebook and attempted to verify notifications were off, it looked like a dozen users were inside my phone, every single apps settings pages were flashing across the screen, options highlighting moving to other choices and a good 50 pages in about 10s as I frantically held down power and power down in attempt to force the phone to reboot, the phone rebooted, and everything appears to be fine...

The heading of this post is what Google calls my phone now, will work on updating recovery or trying to find a different one to use since this device is not on their list of supported devices, need a recovery for the D801 now that the device thinks that is what it is, or do I look for the D800 still?

I see we lost Knock and the ability to enter that secret menu with 3845#*800#, tried 801 too, and all the icons are large, will have to see if there are UI options to play around with, battery was going fast initially but it had loaded 40 apps, now after a full charge and 6 hours off charger down 2%, which was my former rate with minimal usage, 1% every 3 hours. Phone appears to wake up to a semi state whenever I pick it up and it sees my face, perhaps that replaces knock. The icon for telling us if we were on 4G or LTE was replaced by some generic icon from previous CM builds and I can't tell what speed I am on at the moment as those are all much smaller. Few of the APN settings were changed, had to re-add hipri and tfdata to my settings, haven't tested MMS yet. I guess the star means I am on Sleep mode with only starred people given priority so work doesn't call me late at night. I was actually enjoying all the options this G2 had over my previous phone while in KitKat and miss many of the features, it is a toss up for me as I hope to discover what benefit this has over the previous stock ROM other than being able to rid myself of the AT&T apps... Liked the roll over in app menu, not having to pan back to beginning on stock ROM too and window in window ability, haven't found that yet... Time to explore...

Also If I add any other device specific files-apps-zips such as recovery, radio, kernel mods onto my device which device do I grab files for now?
