[T-Mobile LG G2] vaximily:
tl;dr - TWRP touch screen won't work after installing custom ROM, much hassle to unbrick, looking for a "bumped" (still not actually sure what that term means) or otherwise modified version of TWRP that won't go haywire when installing a custom ROM.

tl;dr 2 - Also interested in the LATEST "stock-based" ROM recommendations anyone may have... G3 backports or whatever. She needs her Camera to work well but older 4.4.x and 5.0.x OS is missing a lot of new functionality and compatibility with new apps.

I'll just start out by saying that I've figured out just about every way to brick and subsequently un-brick this device that is feasibly possible, and am considering starting a thread specific to those various methods... but that's not what this is for.

This is an issue I've encountered a few times now, definitely on my girlfriend's T-Mobile LG G2 D801 with Lollipop (30B and now again on D801 30C), and iirc, also on KitKat.

I'll explain what I can remember, most of this has been done in the middle of the night after many frustrating hours of attempting various methods... I have to say, this phone has been much more difficult to mod compared to my previous experiences with Samsung and Nexus devices.

I had gotten this device all the way through to CM12 or 13 a year or so ago but recent issues made us decide to attempt to revert back to a Stock-based ROM.

Steps:

1. Root (ioroot / Autorec, can't remember which or for what reason, I have multiple versions of each)

2. Install TWRP Custom Recovery (most recently and successfully using a modified version of the "30B Freedom Tool", although I haven't tried that on 30C - yet.

3. Transfer custom ROM & Kernel to SDCard.

4. Boot into TWRP and install custom ROM & Kernel - most recently GoogleEdition 1.5 and then DorimanX 12.0 Kernel

5. Clear Cache / DALVIK Cache.

6. Reboot device. This is where the trouble begins...

Results: Won't boot into OS at all, instead I end up at the text-based "fastboot" screen, which after multiple tries I can eventually get back into TWRP or into Download Mode.

Once in TWRP after installing custom ROM, the bottom ~1" of the screen won't respond and all other touches aren't accurate... playing with it, I can usually eventually get into some of the TWRP screens, but for most purposes it's about useless.

I managed to restore a backup of the original 30B system image via command line over MTP using ADP TWRP commands, but that bricked the phone in an entirely separate manner where I couldn't access Recovery anymore and the system wouldn't boot at all... I ended up using the LG Update tool to get it up to 30C, and was surprised to find that it still had the restored backup data (apps, pictures, settings, etc), and the phone is now working again, albeit back to stock recovery.

Now, as I mentioned, this isn't the first time I've run into this "phantom touch" issue in TWRP on this device, although the circumstances seem to be a little backwards this time vs when I was taking the device over to CM12/13. I think I remember something about a "bumped" or otherwise modified version of TWRP being out there, but I can't find it now or put my finger on what the changes were.

Has anyone else run into this? I am hoping I've just overlooked something, but days of digging through threads hasn't turned up much.

/edit/ To give you an idea, attached is the folder I've got files stored in... with tons more in Archive and Stock-Based... I've used them ALL at some point. I'd like to get enough info in here to write a Step by Step guide for new owners who are picking these devices up on the cheap, and would appreciate if anyone wants to help out with this!
