I haven't been on here or using Android as a daily driver for quite a bit, so here is a short story:
I was bored and accidentally deleted lgsystemui.apk one day back in October 2015 (I think)
Then I bought a LG Optimus Fuel with an iPod Touch and in February 2016 I bought an iPhone 5S and put it on TracFone's BYOP program.
Today, I was riding my bike and I checked my phone and dropped it face down. The screen is ok (except it popped out but I put it back) and a few dents. This experience made me realize why I should have a backup phone (one usable since the LG Optimus Fuel doesn't suit my needs). I pulled out my bricked Ultimate 2 and am now exploring new ways to fix it. I asked a similar question awhile ago but now I have learned the basics of ADB (I bought a Fire 2015 that I soft bricked once or twice but fixed it) and I'm also not stupid enough to delete important system files. Of course with my luck, my Ultimate 2 does not show up in ADB. Does anybody have a stock ROM (or at this point I don't care and any rom is fine as long as it is for the phone) and know how I can install it (or to just get the stupid APK on there I was using the LG G3 ROM with TWRP last time I checked). Last time we came to the conclusion to get a replacement or an upgrade, and I just bought a new phone, and it isn't worth it to replace since I have my iPhone, I'd just like to fix it as a backup.

EDIT: I know how to fix this phone if it is possible to enable ADB without the phone fully booting. Which it probably isn't. Don't make this high priority, since this phone isn't my daily driver. 

TLDR: I deleted LGSystemUI.apk on a phone, asked about it before, got a new phone, almost broke it, and want to fix it as a backup. What annoys me is that I had a recovery but now I don't (unless I need the SD card for it to work). Or, could I make a bootable TWRP or CWM recovery SD card and then boot from that to fix the phone (or at least enable ADB)?

Thank you. I've been known to write good (or at least by myself) . Anyway, all I remember was that when I started messing around and I flashed ROMs, I installed a recovery to flash the ROMs (and make backups). I think I only flashed a ROM once, but I might have done it before after modifying some files, but I think TWRP was only installed once. I never uninstalled it. When doing the button combo, it says "Factory data reset" and then, after telling me controls, it says "Erase all user data & restore default settings?", then after selecting Yes, it asks to confirm, and I hit yes again. Then it says "Factory Reset Processing...", shows the LG Life's Good Powered by Android "splash" screen, then just bootloops some more.

Well that's ok. I learned a lesson and have like 2 other phones a tablet and some other stuff. Anyway, it makes an awesome paperweight!
