Thanks XxZombiePikachu. I didn't know the bootloop issue last week and was able to get back and running to my TWRP 2.6.3.4 and 4.2.2.
I just finished upgrading OTA using the LG Mobile Support Tool which was super easy. Once updated I didn't have root access. However, I tried the IOroot25 which now supports D803 and it worked! http://xdaforums.com/showpost.php?p=48709232&postcount=869 I have root access back.
EXCEPT when following the instructions, my phone was wiped clean as if right out of the box with KitKat 4.4.2. Luckily I backed everything up using Titanium so I'm in the process of restoring all my apps BUT I now have KitKat 4.4.2 with root access.

2Bell D803 Root, FOTA, Fun
Just the other day, I decided to root my LG G2 (Bell D803), and found a TWRP Recovery that installed properly (was warned in several locations NOT to use a D802 recovery or ROMs!). Got myself rooted using ioroot (lovely tool), nice new recovery, then found no ROMs really ready for use on the D803 (although I hear some folks have been able to get D802 ROMs working with effort). Barely had time to start exploring my further options when the FOTA update appeared. Not thinking, I grabbed it immediately!
And then the phone went into a boot loop -- Recovery was my only option. Tried looking around within Recovery for any sign of the FOTA update files but later found it goes to a partition. Apparently wiping this partition brings the phone back to a usable state.
adb shell
dd if=/dev/block/platform/msm_sdcc.1/by-name/fota of=/sdcard/fota-backup.img
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
Once back in usable mode (still with root at this point, but no shiny new KitKat), I did some digging to try figure out how to get rid of my new Recovery so I can get the update. The shortest possible path I found: the LG Mobile Support Tool. I ran it, it said there was an update. Downloaded the update and all was good -- aside for remnants of root being left over (just needed to uninstall Superuser app; wasn't working at this point anyway).
So for now, I'm rootless but fully updated.

Use the tool in this thread,I was rooted and running TWRP recovery. I put it in download mode before running the tool and it auto-detected me as d803. The whole process took about an hour, but I am on 4.4.2 now unrooted, no wipe.http://xdaforums.com/showthread.php?t=2471370&highlight=d8031
Yes. Just doing the update it offered restored my Recovery back to stock and upgraded stock ROM. No wipe necessary and only thing lost was root. There was a brief warning that updates are not available on rooted setups, but I haven't seen that again after the initial boot. I suspect removing Superuser solved this but I'll keep you posted.
