Hi I've been lurking here for a while back when I had my One X and I hate for this to be my first post but I bricked my G2. Well, actually At&t did. I followed garyd9 method to get rooted kit kat and that worked great. The problem is I installed Xposed framework and a root hider along with it (so I could use isis wallet) so AT&T pushed this recent update to my phone anyway. I did a titanium backup of my text messages but not a nandroid...
Now I can only enter recovery TWRP 2.7.0.0 I managed to replace it with 2.6.3.3 with adb push and then install so I hope not everything is broken.
However, I cannot enter download mode or even boot to bootloader. Everytime I turn my phone off all that shows is the LG logo with a black background and then TWRP loads. I would replace my .img (boot, aboot, etc.) but I can't enter fastboot.
Any help would be greatly appreciated.
Well since you had an ota your device isn't it that bad of shape you should try http://forum.xda-developers.com/showthread.php?t=2451696 which is to remove the update

I cannot figure out for the life of me why I cannot install TWRP on my rooted 4.4.2 ATT D800 LG G2. I'm gonna ask some pretty dumb questions because I feel like I'm missing something here.
I installed TWRP2 custom recovery onto my rooted D800 ATT G2, via the "dd" method using adb on computer. All of the pushing and loki stuff worked, but when I boot into recovery, I get a "Secure boot error" and "Boot certificiation verify" error, then I reboot the phone again and it turns back on like normal. I really want to flash the volume boost onto my device but I cannot without a custom recovery.
I've done hours and hours of research and I cannot figure this out.
Thanks in advance.

Seems like you need to flash the patched kernel for the system to boot.

It installs a boot loader that supports recovery plus recovery plus custom kernel which allows custom recovery and boot loader

I have the same problem on my rooted with IoRoot 4.4.2 D802 LG G2 with Stock ROM D80220c-SEA-xx
But I can't install AutoRec: when the install button is pressed, the installer says "app not installed", and the only option is "done".
P.S. I wanted to ask about it in AutoRec thread but I can't post there because I don't have 10 posts yet.
P.P.S I just downloaded it using another computer and it installed fine!
I have same problem with lg g2 sprint ls980 plz help me ??
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.

Hi
I have a d802 lg g2.
Tonight i tried updating twrp via autorec.
after the update was complete i used twrp manager to start a nandroid backup.
After rebooting the phone gets stuck in a boot loop on the LG logo. I can manage to access twrp but the touch is screwed up and the bottom half of the screen dont register correctly so i cant press the buttons needed.
Can I push an older twrp via download mode? if so, how?
Any other options?
Please help

First, I would recommend opening your phone and to check your motherboards model number. There are a lot of refurbished d802's that have altered motherboards. That is why you are facing a broken touch screen and other errors. Please confirm your board number otherwise you may brick your phone.

There's nothing wrong with my touchscreen, it's the updated twrp that don't work properly.

That's not what I'm saying. I think your twrp is drunk because you do not have the correct version installed. Can you check the motherboard model number so that you do not brick your phone.

Situation updated:
last night i updated twrp using cm12, this sent me into a bootloop showing lg logo. i could access twrp but in twrp the touchscreen was acting up making it impossible to do anything.
today ive managed to use lg flash tool with a TOT setting me back to stock 442, after this i used ioroot and i tried installing twrp via autorec and this has put me in an endless boot to twrp and im not able to do anything from there, but touch works in twrp now.
using lg flash tool now fails each time

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?
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.
