I've done this in the past, but now it just goes to a black screen after flashing TWRP. I've tried multiple methods (Flashify, adb, etc). I've tried multiple versions of TWRP for the D800 too. Any suggestions? I had SuperUser, and I then tried SuperSU (when using Flashify). This doesn't affect anything.
Thanks
EDIT: looks like I'm on D80010o now. I guess this happened when I restored my phone using the LG Flash Tool. Will all ROMS/addons work on D80010o now that I have TWRP on here?

Hi all,
I have put myself/phone in an interesting situation, which I am hoping the community can help me with.
I recently bought an LG G2, dold with stock 4.4.2. I proceeded to root it, and tried installing custom recovery.
I first installed ROM manager, which didnt work.
I then tried flashing twrp through adb using loki, which gave me a 'this is not a loki file' error.
I eventually realized that they had closed the Loki loophole in stock 4.4.2.
At this point, trying to enter recovery wouls give me a 'secure booting failed' error, making me have to reboot the phone again.
I then unrooted my phone, and factory reset it. I realized Clockworkmod recovery (which ROM manager installed) persisted despite the data wipe, so I unchecked that option in ROM manager and wiped it again.
My thinking was that I vould now downgrade to 4.2.2, install custom recovery there, then flash 4.4.2 whitout losing root or recovery.
Problem: I can't do any of this, because I can't reroot my phone with ioroot25. It fails as when it reboots inti recovery it gives me the 'secure booting failed' error.
Thanks for any help. I simply want to root my phone and if possible, have a functional recovery in order for me to flash some mods. At least being able to have it rooted again would be sweet.
Hehh...
Last thing you can do is try to flash with LG Flash Tools Method or LG Support Tool
Flash stock recovery either via fastboot / or dd(on linux). Then you can proceed further.
Or ^ kdz via download mode.
I have a similar problem. I restored the stock recovery via adb using a dd command. Then I unrooted in order to accept the latest OTA. The OTA fails with a "suspected root" error. Download mode still has "ROOTED" in red letters. At this point I gave up on the OTA and wanted to get back to where I was.
IOROOT25 doesn't work because when the phone reboots to recovery mode, I get the broken android with the red triangle but nothing else on the screen at all. There are no options, nothing. Eventually it reboots. I've done a factory reset to no avail. Recovery seems corrupted.
I need instructions for flashing the stock recovery with no root.
I managed to get my recovery rewritten using the LG Mobile Support Tool on a different computer. Then I was able to root again using ioroot25. I'm not sure why I couldn't run on my own laptop, but it's fixed now.
Currently I am running a LG G2 LS980 4.4.2 zvd. Rooted via stumproot. Twrp rrecovery 2.8.5.1. I also am running affliction custom rom found in the sprint lg g2 section. The problem i am having its that when I try to load a different custom rom I always get stuck in boot loop. I always do a full wipe and factory reset. I have tried liquidsmooth, blisspop, cm12, validus and a couple others, always gets stuck in boot loop. Today i did a full wipe again and installed affliction Rom again and it worked but the others still won't. I have also tried to downgrade my radio to zv8 or zv7 since that has been recommended on some threads i have read, but the files i downloaded off of a link found in here say they are corrupt when i try to load them and it doesn't work.
Does anyone know how to help me?
Hello, it sounds like you might have the wrong bootloader. You need a zv8 radio/modem and a jb bootloader for aosp lollipop ROMs.
So i downloaded zv8 radio zip from a link shared in another thread. Do you know another source for those? How do I change my bootloader? I have tried looking for that but have not had much luck.
Google "LG G2 modem" and the first result should be a xda thread with all the modems for all the modems for all the lg g2 variants. Download the ls980 zv8 modem. For the bootloader you need an app called autorec. Google "LG G2 autorec" and download autorec for the ls980 and run the app. Make sure you have the twrp 2.8.5.1 zip on your device because autorec also installs twrp 2.7.0.0 which is old. Just go to recovery and flash 2.8.5.1 to update twrp.
I will try to get new zip for zv8. Autorec is how i got twrp on my phone. I have upgraded twrp to 2.8.5.1. Although autorec does not show up in my app list currently, maybe when i installed affliction rom that app left by i kept twrp.
So i reinstalled autorec and upgraded twrp to the most current. I also redownloaded the zip for zv8 modems. When i try to install zv8 zip in twrp but it tells me the zip is corrupt and will not load.....
Could use some help/advice.
I restored the kdz using the lg flashtool to jellybean. I didn't update directly kitkat. Instead, I used towelroot to root, then I used autorec to install twrp 2.7.0.0 (or whatever it was). I then flashed twrp 2.8.5.1 and I flashed CM12. CM12 doesn't boot at all.--stuck at LG logo. If I try to use download mode to reflash kdz, it doesn't detect the phone. I can access phone in TWRP via ADB. and it detects it. Is there a way to restore the download mode to detect the phone.? I think this mess happened b/c I didn't update to kitkat and the partitions didn't get updated, but I'm not sure.
Any advice to either get download mode working again from within TWRP, or get CM12 working would be appreciated.
Thank You

You need to install the kk bootstack for your device and wipe data.
Sent from my LG-VS980 using XDA Free mobile app
I rooted with kingroot, it worked and then tried to replace it with supersu using supersume. Everything worked fine. Supersu updated and asked for reboot. So I rebooted the phone and it got stuck at verizon screen. Factory resetted it from recovery menu, still stuck at verizon screen.
LG G2 VS980
No custom recovery
No custom rom
Download mode working
I remember turning USB debugging on but it could be off I'm not sure.
Please help
Fixed it by flashing kitkat kdz file with lg flash tool. (This is my other account, idk why I made the OP one)
So i've tried rooting and installing root+TWRP over a script on my lg g2 d802 which sent the phone into a boot loop. Then i downloaded a Stock ROM (i didn't find mine so i just chose one from my country) and flashed it on the phone. I then rooted it with some script i found on youtube IOroot, which worked and and proceeded to install TWRP over AutoRec, which worked aswell BUT i was not able to get back into the system because of the phone boot looping again. I was able to go back to TWRP but not into the system itself. So i just reflashed the phone again.
Does anyone know what my mistake is here? I am pretty new to this. Could it be that because i have a different Stock ROM it doesn't work? Tbh, I don't know if i will destroy it by installing a american Stock ROM on a german phone. I've read a lot of tutorials but many are down and most of them lead to AutoRec or this Auto Script from here.
EDIT: Ok, nevermind. I installed some Stock Lollipop ROM and with that everything was pretty easy. Installed LineageOs 15.1, works great.
