Restore Recovery D801 - G2 Q&A, Help & Troubleshooting

Hello guys. I rooted my phone and i installed TWRP using the AutoRec app. Now in the past with my phone rooted only and with stock recovery if i want to get back to stock i used the LG Support Tool. But now that i installed the TWRP when i use the LG Tool and puts my phone to Download Mode i get an error. Secure Boot Error, Cause Certifications Verify and because of that i cannot enter download mode and i cant get back to stock. I have looked for ways to restore stock recovery because i believe the error is because of this but i cant find a solid tutorial. Every were i look people convince the OP to keep using custom restore or no one answer the question. So to be cleared the stock rom installed is 5.0.2 and it works i can use it and the TWRP also works i can use it the only thing broken is Download mode and i ant to restore stock recovery. T-Mobile LG G2 D801

[Q] Please help... D800 flashed to D802

So I am not sure what I did, but I was just trying to flash the Grievous ROM earlier and it would not work, just kept going to a black screen on start up even though I didn't get any errors when installing. I retardedly forgot to make a backup so I have nothing to go back to. I tried to go into download mode to restore through the LG tool, and amazingly somehow it now says my phone is a D802.
I can still get into recovery and download mode and haven't seen fastboot yet, but I can't get my computer to recognize my phone in adb or sideload while in the recovery menu... Not sure what to do. It sucks that this phone doesn't have removable SD.
Anyone got any ideas? I've looked through other threads of people who have had this problem and luckily(I think) I still haven't got to fastboot. I was thinking if I can just get the stock files on there I can flash it in TWRP without having to even use the LG Flashtool, but I am at a loss for how to get the stock ROM on my phone.
WHAT DO I DO?
Install the kernel for the d800. To hey your phone to be recognized in recovery you will need the proper drivers, try pdanet. Drivers

Okay I successfully got adb to work in the TWRP menu with the pdanet drivers, and I pushed the stock rom .zip to my phone but it won't let me flash it. Where do I get just the stock kernel?
Nevermind, got the ATT stock rooted rom from scotts site to push and install, which still gave me a black screen but afterwards but made download mode work, so got it back to stock! YAY!

[Q] LG G2 downgrade to JB with custom recovery?

Hi all,
I recently bought LG G2 d802. 2nd day I installed GloudyG3 rom. Everything was fine except the VOIP applications (Skype, Viber...). Voice communication using these apps was impossible (see LG G2 KitKat VOIP/Skype bug).
I wanted to revert to stock. I saw the guide to revert to stock using LG Flash tool. I've done that step by step but program stucked, and I bricked my phone. There was no download mode, no recovery mode, no nothing. There was however qhsusb_bulk recovery option. I tried to fix the phone using this guide: http://forum.xda-developers.com/showthread.php?t=2582142, but after that I got no recovery and lost this way of recovery too.
After I replace the phone I want to revert to Jelly Bean because I really need VOIP apps (Skype, Viber, etc...).
Is there a way to flash Jelly Bean rom (stock or custom) using custom recovery? After all of this I am REALLY afraid to use LG Flash tool again.
By the way is it possible to do all rom manipulation using custom recovery and never use LG Flash tool* As the user who wants to use rooted phone I don't want to install OTA updates either.
Thank you in advance for your answer.

[Q] Emergency help needed

Well I restored my back up of a rooted VS980 rom, 26A version. I did so because i honestly grew tired of the bugs with my LP rom i was using so i decided to return to stock and update to the 27A firmware. When I went to allow the download to install all it did was reboot to twrp recovery and now I cant flash any rom to get it operational, I for the love of god apparently dont even know how to enter download mode. Ive read its hold vol up and plug in but that does nothing but once again BOOT INTO TWRP recovery. I just want my cell back to stock with no root and ill make any needed mods as i see fit.
Ive tried to use the flash tool but even that requires a download mode which i can not enter, and it wont even display correctly for me anyway.... Any one have any advice?

Bit of a problem here.

I got my spare G2 today and have run into a bit of a problem with rooting it. The root process seems to have gone fine. It says I am rooted and I can use Root Explorer to remove bloat and such, but something seems to have gone wrong with the recovery. If I try to boot into recovery, I get an error message that says something about Secure booting error. It has some other info, but the screen goes black so quickly that I can't make out what it is saying. If I hold the power button down, I can reboot the phone as normal so it's not bricked, but without a recovery I can't do any custom Roms. I've tried various methods to flash a new recovery and they all said they were successful, but I still can't get into recovery mode.
Does anyone know what I did wrong or how to get around this? The phone came with firmware 4.4.2 26a if that means anything to your advice.
Thanks a million for any help.
Looks like your recovery gone. Flash stock Lollipop Kdz then root and install TWRP with Autorec from Google Play.
Thank you. Just did the TOT method to flash back to stock 26a so thankfully all is back to normal. Now i'm afraid to try it again because I don't know what went wrong. The ioroot version I have is an older version for 24a or backwards. That's the one I used for my original G2. So I tried using a different method (one click) for this phone and it was a mistake. Could I use the flash tool to kdz back to 24a and then root using the method I know or do I have to stick to 26a for hardware reasons?

Help me get beyond Jellybean -- Weird recovery problems

Howdy folks -- I'm having issues with my G2 that I hope people here can help me with. I've already had some advice in the Noobs thread, so thanks for that.
My phone is a LG G2 D800 (AT&T) and is unlocked, being used on the Rogers network. The previous owner of the phone had installed CloudyFlex, which is what I was using until recently.
Here's the story in a nutshell:
On my first attempt to upgrade my ROM from CloudyFlex, I booted into recovery (TWRP installed by the previous owner) and then flashed the newest TWRP for my phone. I then realized I didn't have all the files needed to do the upgrade, so after the TWRP image was successfully flashed, I went to "Reboot System". Doing so gave me a non-responsive phone (LG logo then nothing but a slowly flashing LED).
I managed to get the phone into Download Mode and followed the instructions for LG Flash Tool in the first post here exactly: http://forum.xda-developers.com/showthread.php?t=2432476 which gave me a "stock" functional phone again, but one now running Jellybean (4.2.2, software version D80010o). I'd like to be on Kitkat or (preferably) Lollipop.
I am able to root the phone easily using the LG One Click Root tool. No problem there.
So that's the story. I now have a AT&T D800, unlocked and running on Rogers with Jellybean 4.2.2 (D80010o). I would like to bring my phone into 2016 by updating it to at least KitKat, preferably Lollipop (if I can). The problem is that I can't get a working recovery. Here's what I've tried:
Flashify: following its instructions exactly seems at first like it's working (I get some kind of "success" message) but when it then goes to reboot the phone, it reboots to a black screen (phone is non-responsive -- have to hold down the power button to shut it off, then turn it back on, at which point it boots normally into Android)
TWRP Manager: I've tried it as well, and get the same outcome as Flashify (apparent success followed by a black screen etc.). Once the phone is on and back into Android, TWRP Manager seems to think that TWRP is not installed.
AutoRec: I installed the version from the thread here: http://forum.xda-developers.com/showthread.php?t=2715496 ran it, and again it appeared to be successful. When it rebooted, it did go into recovery, TWRP 2.7.0.0 or something like that. Then I went to "reboot system" but got the same problem as before -- phone non-responsive, slow flashing LED, had to go back into Download Mode and flash the Jellybean TOT file, etc.
Can anyone help me figure out what is going on? I just want to get my phone to a nice stable Lollipop state with decent performance and battery life. Failing that, KitKat. Not sure what to do next.
Crisis averted: I managed to get CloudyG2 2.2 running on my phone and all seems well. Here's what I did:
I installed stock KitKat on my phone using the procedure outlined at http://forum.xda-developers.com/showthread.php?t=2663369
I then rooted the phone with ioroot (following its instructions)
I then used AutoRec to install recovery. For some reason I'm only ever able to boot to recovery directly from AutoRec -- when I try to get into recovery using the usual techniques, the phone locks up. I literally have to reinstall recovery every time and then say "yes" when AutoRec asks me if I want to reboot into recovery. Not sure why this is. The TWRP version I see is 2.7.0.0
I then flashed the KK bootloader and then CloudyG2. So far so good.
I'm a bit too shellshocked to try to install a Lollipop ROM on this phone right now. Maybe some day. In the meantime, many thanks to those who helped me out on other threads.
Why didn't you just tot to the latest rom?

Based on comments at http://forum.xda-developers.com/showthread.php?t=2432476 I was under the impression that the farthest I could get would be Jellybean. Then found the other thread with the KitKat TOT. That enabled me to use Autorec (though recovery still works wonky on my phone) so I now have CloudyG2.
