Unrooted, can't reroot, corrupted recovery on 4.4.2

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.

HELP! I can't install TWRP on my LG G2 D802.

PLEASE let me explain and read me, and forgive me for my bad english writting. I'm a noob on this theme.
I have a LG G2 D802 32gb, running Stock Kitkat 4.4.2 on version "D80220d-466-92".
I installed Lollipop and got back to Kitkat many times by using Flashtool. Also, I rooted and installed TWRP with AutoRec in Kitkat a lot of times, I installed Custom ROMS, I changed Bootloader and Kernel (Dorimanx), and once I had a problem with storage, I installed by mistake a 16gb Stock KK version in my 32gb, but I fixed it.
Last week I installed Mokee ROM with TWRP, I made the Wipes (Selected all options: Dalvik Cache, System, Data, Internal Storage, Cache. Because I use USB OTG), I changed bootloader with Nevax BootloaderChanger(Lollipop Bumb), I installed the GAPPS. And it worked fine. BUT, when I tried to go back to KK Stock, Flashtool didn't work, like it didn't recognize my phone (my PC did recognize the phone, I have right installed LG Drivers). I had to converted the KDZ KK File to Zip, and flashed it with TWRP, that was the only way to go back to stock.
It seemed to work fine, but I tried re-installing KK Stock in Flashtool, and this time it worked. When I went to storage it showed just 10gb avaible, and when I got in hardware info it showed 32gb memory. And I tried fixing storage again, and it worked.
The problem came here, I noticed when I get in Download Mode, it says ROOTED in red letters. And the past times I got back to Stock these letters didn't appear. Then I didn't do anything.
I started the phone normaly, but when I tried installing Towelroot and WifiKillPro, the device didn't install them, it said "Application not installed". I could install APK's and AutoRec, Quickboot and Rootchecker normaly. Then I decided to Root the phone with ioroot25 and it worked, I used Rootchecker and all was fine.
BUT when I installed AutoRec again (I gave SuperSU permissions), and hit YES to install TWRP it just said "checking for loki...installing" and a few minutes past, I closed the App and re-opened it, but this time it said:
"error: Tried to install loki_tool, no luck, please try manually installing loki_tool, app will exit".
I chose to install it with PC (recovery.bat), but it says:

Reboot into recovery now [y/n]?
-----------------------------------------------------------------------
I used Flashtool again and again, and the red letters (ROOTED) didn't disappear.
I never had problems with this version of Kitkat, I could rooted it and install TWRP AutoRec normaly.
I made a Wipe/Factory Reset, and I rooted with ioroot25.
I WANT TO KNOW IF MY PHONE HAS A PROBLEM.
It is working fine, but the things I told you don't let me in peace.
NOTE:
I fixed storage, with the Total Commander and Minimal ADB and Fastboot method.

TWRP/CWM Method of SuperSU caused boot hang on custom rom

Hi guys, I was able to root my G900V, unlock the boot loader into Developer mode, re-write the recovery with TWRP and install AICP custom rom. It was working great, I put Titanium Backup on my phone and it warned of an old version of SU. It recommended I upgrade SuperSU, so I installed the SuperSU app. When it came up of course it detected the same thing (old version of su) and recommended update. I have never used the TWRP/CWM method so again I tried Normal mode. It asked for access and I granted it, spent some time acting like something was happening then failed. I rebooted the phone and tried again -- same thing still failed.
Since I had TWRP installed, I thought I'd give the alternative flash a try. When I chose it, it booted into recovery and flashed a zip file. When it rebooted, it tried to bring up the OS and it hangs at the AICP logo. I can still get into recovery but the OS won't fire up. I'm not sure where to go from here, I think I can start over with ODIN but I'd rather know how to repair this situation (if it's possible) since I started to get the phone set up...
EDIT: By the way, the rom was the AICP Nightly from 12/30 and TWRP of 3.0.2-2.

Solved
I downloaded chainfire's latest SuperSU zip file: https://plus.google.com/+Chainfire/posts/WrCvex7KAZR and flashed it in TWRP. Got me rollin' again.

OnePlus 5 stuck on stock rom after trying brick cant flash anything now

So im trying to root my oneplus 5 and i started off by using Lineage OS but i wasnt too happy with it and i liked Oxygen OS much better so i decided to go back to it and while doing so like an idiot i wiped everything in twrp including the storage with all my ROM files and the phone was bricked and after a long struggle i used the unbrick tool which is called MSM tool which installed oxygen 4.5.8 using some some Qualcomm mode or something and it booted and worked fine but ever since i wasnt able to download the oxygen 5.1.1 update through the phones update section, it reaches 100% and says signature verification failed and goes back to 5%. So i tried downloading the latest Open Beta from the OP site and tried local upgrade which said installation failed so i try installing it locally through the Oxygen Recovery but again Installation failed so i try unlocking the bootloader again and installing it through twrp and it just keeps showing the boot animation forever( i know people say be patient but i waited for 20 mins+). So i decided to use the unbrick tool again and now im stuck on the OOS 4.5.8 unable to update the phone.
I tried to flash the latest oreo through twrp several times and just tried flashing it through so many ways where none worked , even adb sideloading it worked till 47% and said installation failed and everytime this happens i have nothing left to do but use the tool and unbrick it again and this takes so much time as i have to unbrick and then do the first setup and then go to fastboot and unlock the bootloader and do the setup again and transfer the files and then install twrp and flash.
Nothing has worked so far
And now even when i go back to the 4.5.8 stock after unbricking for some reason it just doesnt connect to any wifi , it just says Connecting and then saved and then disabled and repeat, only my mobile data works.
I tried to flash lineage again but got an error 7 with it or something and im back to the stock unbricked state without wifi and all i can do is unlock bootloader and install twrp.
If anybody has any suggestions and can help me please do so immediately. I require my phone urgently and need to fix this fast.
Thank You !
(btw im in India and do local service centres fix such issues?)

Make sure you use newest twrp. And also flash firmware for 5.1.1

i am using the latest codeworkx twrp 3.2.1 and when should i flash firmware? can you just give the process i should do? stuck at 4.5.8 without wifi with twrp and unlocked bootloader

Wipe everything except internal storage, after that click format data and type "yes" to accept. Then download oos 5.1.0 firmware from here https://sourceforge.net/projects/cheeseburgerdumplings/files/15.1/cheeseburger/firmware/ and lineageos 15 (or any rom you want now), gapps and move all 3 packages to your phone. Flash firmware first and then reboot to recovery. Then flash rom or gapps and reboot

You have to flash the latest TWRP from twrp.me, then download the latest OxygenOS build. Reboot into TWRP, wipe data, cache, system and flash the latest build, then just go to wipe > format data, type "yes" and reboot

Lol man your OP5 is not bricked, if you can boot on TWRP, you can install all that you want
I advise to Format Data/Storage, Wipe everything and install xXx 10.7 (OOS Custom with a great Aroma installer), choose decrypted, it's better if you want swtich rom in the future AOSP > OOS > AOSP

bro i have same probleme after install any rom custom or official , always stuck on boot logo , any solution ?

no solution??

Hi there, I happen to own the same phone (d855TR, Android 5, v20n-global-si, Kernel stock: 3.4.0) and I've been trying for some days... But today, I have succeeded.
That's how I've got it done, finally:
1.) Root your phone using KingRoot
(I've used version 5.3.8, but the app will anyway update automatically, if you are connected to Wifi)
(I've tried a lot of other rooting strategies, too: LG One Click Root, Towelroot, Stumproot, but for this specific phone, they all failed.)
2.) Install "AutoRec"
(Initially, I left away this step, but this resulted in a "Secure Boot Error" while rebooting and the following steps failed, then. Installing TWRP manually, via official app or via ADB failed at this step, too. But after installing "AutoRec" everything went fine.)
3.) "AutoRec" automatically installs TWRP, but it is an older version (2.8.7.), so you should update TWRP to the latest version.
4.) Having done this, you should be able to install any CustomROM. I've installed LineageOS 16.0 and up to now, everything seems to be O.K.
Basically, I followed this guide:
https://forum.xda-developers.com/showpost.php?p=67602605&postcount=749
(Here you will also find a download link for "AutoRec".)
I applied this guide successfully to the d855TR variant, inspite of the warning in the disclaimer not to use it for any other phone than d855. According to this guide, it was designed for 30b-firmware, but my version was 20n and it worked.
Good luck!

Thank you very much, I will try this.

Initially, I've installed TWRP without the official TWRP App and I managed to install LineageOS 16 as CustomROM. But as I installed the official TWRP App later, strange things happened: Suddenly, I wasn't able any more to boot the system, and only the start of the CustomROM showed up, but then the phone automatically rebooted into recovery (TWRP).
So maybe, it will be safer not to install the TWRP App on the d855TR. TWRP without the "Official TWRP App" is doing fine (after re-installation).
