[Q]LG D802 4.4.2 TWRP Not Opening - G2 Q&A, Help & Troubleshooting

Hello I need help about an Android app called "AutoRec". I have rooted my LG G2 D802 4.4.2 with IOroot but I did not get SU app so I downloaded one from google play called "SuperSU" and I have checked and it says my device is rooted properly. I wanted to do a EFS Backup just in case so I started searching how to flash a custom recovery image. Luckily I found AutoRec and done it as instructed. But when I enter recovery mode from my phone it shows the standard stock LG recovery instead of TWRP 2.7. But after using the app again and tapping go to recovery from the AutoRec app after finishing I could use TWRP but once rebooted, it does not enter TWRP again when I try to enter to recovery mod, instead it shows the stock recovery. Can any of you help me please? Thank you.

[Q] Trouble when trying to install CWM/TWRP

Hi everybody,
I've installed KitKat 4.4.2 via OTA last saturday. Now, when I try to install a recovery (CWM or TWRP) in my D802, I get problems.
First of all, I rooted my device with ioroot25. Then, I installed ROM Manager, downloaded CWM Recovery (non-touch), reboot with recovery. It starts "Android system recovery <3e>" instead of the cwm.
Same problems with TWRP.
I tried also to install the recovery via adb, but nothing. When i try, the cmd shows and error: Failed to open aboot for reading.
How can I resolve?
Thank you very much
Dan

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.

JB broken download mode - TWRP works

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.

TWRP Install help needed - "Critical Error" instead of recovery mode

Hi,
I have rooted G2 802 International version, with stock ROM V30B.
Now I try to install TWRP there.
Tried multiple image versions, including from TWRP download site,
last one from here http://techerrata.com/file/twrp2/g2d802/openrecovery-twrp-2.8.5.0-d802.zip
Installed through adb shell,
Code:
dd if=/data/local/tmp/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
When I try to enter recovery mode I get a brief "Critical Error" message (in text mode), then promp to choose whether to reboot or enter download mode. No TWRP.
Any ideas ?
You're on LP bootloader which does not allow you boot custom kernel (locked bootloader). Downgrade to KitKat bootloader, custom recoveries and kernels are BUMPED (signed), and KK bootloader thinking these images are official, will pass it to boot.
Use AutoRec for LP from Google Play, it will do everything by one click. Because after flashing KK bootloader, official kernel of Lollipop cannot be booted too as i remember. Anyway AutoRec app will downgrade bootloader, flashes recovery TWRP and modded official kernel image, so will do everything you need.
AutoRec, you had one job...

AutoRec seems not to work. I installed the VS980 version for the Verizon variant of the phone, but all the app has is a picture of lollipops. Tapping the one at the bottom restores my (corrupted) backup, while tapping the one at the top does absolutely nothing. Any ideas?
UPDATE (8:42PM) -
Figured it out! In the SuperSU app, I disabled "mount namespace separation" and "tapjacking protection" before rebooting and trying AutoRec one more time. This enabled the hidden install button behind the lollipop icon in the app and allowed TWRP to be installed instantly. Hooray!
Hi, I tried to install TWRP using Autorec. But my phone stuck on fastboot mode. although the phone said it is d802 varient after I remove the back it says ls 980. I can run fstboot commands but not adb. Itried 5 different computers with win7/8/10. No good results. worse case is, no download mode at all. So I can not flash the phone. I tried to flash TWRP using fastboot but nothing changed. Can some one please help me

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
