HELP! I can't install TWRP on my LG G2 D802. - G2 Q&A, Help & Troubleshooting

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.

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.

D802 CM13 SuperSU binary needs to be updated

Hello!
I have spent around 5-6 hours tonight fixing my phone. Before it had CM13 working just fine but my recovery didn't work (got an error when trying to enter recovery). I manged to solve that problem by doing lots of things I have already forgotten about now and to be honest I didn't really have any idea what I was doing as I am very new to this and have no knowledge about it.
Right now my CM13 works just fine. No problems booting. My recovery works just fine. I have CAF bootstack and the latest TWRP recovery that was mentioned in the guide. However, my SuperSU doesn't want to work properly. At first, I had to download the SuperSu app from Play Store. I don't know if that's how it is supposed to be. When I start the app it says "The SU binary needs to be updated. Continue?". I press Continue and it says "If you have a custom recovery like TWRP or CWM, that can be used to (try to) install the SU binary. This is recommended for HTC devices. How would you like to install the SU binary?". I have two options: "NORMAL" and "TWRP/CWM". If I press "NORMAL" it proceeds to installing and the circle is spinning and spinning... "Installing, please wait..." After about 30 seconds it says "Installation failed! Please reboot and try again". Rebooting and trying again doesn't help. If I try the TWRP/CWM option it reboots me into TWRP Recovery but nothing happens there. If I reboot system from recovery the problem remains. I googled a bit and found some thread where they said I needed to download some SuperSU zip-file and install it from recovery. I did that but that just broke it even more giving me some error saying SuperSu wasn't installed at all, or something like that. I ended up re-rooting the device and installing bootstack, CM, and GAPPS again.
I have enabled root access in the CM developer options menu, for both apps and ADB. I have downloaded Root Checker and it says i am rooted. In download mode it also says rooted.
Is there some step I have missed? Please help me. I just want CM13, Recovery, and SuperSU to all be working at the same time. Not just pick two, like I have done before.
I had the same problem on my d802. That thing you did in development settings worked for me. Is supersu so neccesary?

Help, no root, no recovery, no download mode

EDIT: This can be marked as resolved -- I used ADB to succesfully send a reboot recovery command to the phone and it worked!
Hope I don't run into any more issues down the road.

Hi guys
In short, my LG D802 International model has lost it's ability to enter DL mode, and the recovery is also missing.
It is now running Stock Lollipop (Custom version) which I installed according to instructions with no problem
However once it was installed I then realized TWRP is no longer accessible. My next step was to then go to the Play Store and download Autorec Lollipop for LG G2 D802
https://play.google.com/store/apps/details?id=b007.autorec2&hl=en
Once that was installed I tried to install the recovery, but the app was unresponsive. The author of the app then mentioned ->If you experience unresponsive button (the button flash doesn´t work) look up this post
http://forum.xda-developers.com/showpost.php?p=65698392&postcount=797
I went ahead to uninstall SuperSU using it's full cleanup and remove function. BIIIG mistake!
That's where the problems compounded, because now SuperSU is not even working and won't let me install the SU Binaries, and the app is telling me to search forums for help
Basically: No TWRP -- No Download Mode -- No Root -- Cannot install SuperSU either!
I'm now stuck with a very unstable phone that hangs and crashes every 10 minutes. I have tried to factory reset but to no avail -- I still cannot use SuperSU.
Thanks in advance

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.

I have no idea why i'm in bootloop.

Hello,
Since my G2 is now out of warranty, i decided to upgrade my stock version ( lollipop ) to ResurrectionRemix-N-v5.8.0-20161128-d802.
Well in order, what i did :
-rooted phone with Kingo because the LG one click root method wasn't working ( MSVCR100.dll is missing" error, install Visual C++ Redist not possible => telling me my version is newer ; probably since i'm running Windows10 x64 )
-installed autorec and got TWRP 2.7.0.0
-i made a backup of everything on my usb disk.
-installed ResurrectionRemix v.5.8.0 and bootstack-d802-CAF
-loaded it successfully
-tried to reboot in recovery for installing GAPPS
-got trouble with lg security when booting since, and never been able to go in recovery again.
-i've been able to still load the system to Nougat, and tried to reinstall autorec... i was rooted and it didn't worked ( loki error ), so i unrooted and rooted it again, rebooted, and i'm now stuck in bootloop when loading Resurrection and i have no clue where to start from now on.
I would accept and be grateful for any idea
Thank you.
Update : i'm lucky, i just plugged it to computer and i'm running Download mode.
