Unbrick ZVD using Recovery Mode (No Download Mode & Unabootable OS) - Sprint LG G2

Currently on ZVD.
On booting throws a "Security Error" and bootloops.
Download mode is not working
Stock Recovery mode is functional. I tried installing OTA zips from here https://forum.xda-developers.com/sprint-g2/general/ls980-zve-ota-zip-update-zvc-zve-t2912488
Both of them error out (one says there's a version mismatch and another breaks complaining about an issue with AAT.apk).
I tried sideloading twrp, cm, Blisspop and other zips. They all fail.
Since I can't boot, get in to download mode and only have recovery mode, is there a way to resurrect my device?

Recovery bootloop. Download mode not recognized by pc.

I have the E975 unlcoked with FreeGee. Everything was working fine until I installed MIUIV6 and then manually tried to flash an upgrade package. (going to miui settings, selecting update and then manually browsing for update package from there).
But the flash failed and my phone is rebooting in recovery now. Tried to flash a new rom. (ARTMOD and CM12.1) but the phone still reboots into recovery always.
I would flash KDZ but the phone is not detected in download mode on my laptop. Any clues? I have lg united drivers installed.

Force recovery mode

Is it possible to force the device into emergency recovery mode to get it back to stock, the stock simply WILL NOT flash and they only thing I can think of would be to get it into that mode to get Keis to flash the stock rom. If I try to flash it in Odin I always get a "Failed (Auth)" error.

Help I don't know how to fix this

i have completely messed up my HTC One M9. My HTC has got cynagen mod 13 recovery and no os i tried to install roms and a stock rom through adb but it keeps on failing and whenever I install a new recovery like twrp it fails to load and my htc is just stuck on the booting screen. I have tried adb, cynagen recovery, twrp recovery (didn't turn on), custom roms,stock rom, adb sideload and it always fails i need help guys.
Download the RUU for your device from htcs website then boot to download mode. This will wipe everything and get you back to stock.

boot certification error with bump'd twrp imgs

Hi
I've tried 3 different twrp images, all supposedly bumped (take this one for example), but when I try to boot to recovery with any of them I still get the boot certification verify error and can't get into recovery
running rooted 5.0 stock wiped, installed by instructions in linked threads
Thanks
update: used autorec, can now access recovery... but it's twrp 2.8.6... can I install fulmics on this version, or how do I update it?
update 2: TIL that you can update twrp from inside twrp and it still works, but that still leaves me confused with the above problems

Stuck during custom install

Formerly unlocked, rooted, TWRP and elementalX kernel install. Reverted to stock for update and now everything is screwy.
When I try to enter Recovery mode I get "No Command". Yes I can press Vol+ and get to some basic menu but it does me no good so I HARD RESET and started over.
Flashed TWRP via my PC but still cant get into TWRP menu in recovery mode. I am about to smash this device out of frustration. What do i do next? I want to install TWRP, MAGISKSU then just flash elementalX.
I cant get TWRP to work properly so cant install magisk..etc.
