Lost TWRP

Verizon LG G2
Rooted
Installed TWRP
Without thinking (doink) tried to install the latest OTA.
OTA failed.
Now I cannot reboot into TWRP.
Installed ClockwordMOD and installed its own custom recovery. Still won't boot into any custom recovery.
Phone works fine other than that.
How can I get back into custom reccovery?
Note: When I turn phone off and try to reboot into custom recovery it takes me to the "reset" screen.. and then IT RESETS the phone.
When I try to boot into recovery from Clockwork or TWRP app it gives me the android robot with the open tummy and red triangle.

The OTA update installed the KitKat bootloader, which hasn't been hacked for custom recovery yet.
Use this to downgrade the only the bootloader and install custom recovery: http://forum.xda-developers.com/showthread.php?t=2715496
You have to root frist. You can use IORoot25 to root the KitKat rom that you have now: http://forum.xda-developers.com/showpost.php?p=48709232

Ok.
The KITKAT rom didn't install properly..
Phone says 4.2.2
Super user and apps that need root to work are working properly. Looks like the bootloader is the only thing that got hit.

Oh. Not sure if AutoRec works if you are still on 4.2.2. Sorry bout that.
If it doesn't work, you can always just manually flash the complete firmware using this guide: http://forum.xda-developers.com/showthread.php?t=2432476. Surest way to get back from failed flashes. You can flash the full 4.2.2 or 4.4.2 KDZ and then start over again. That method wipes everything though.

YIKES.
Well.. it got the TWRP recovery loaded alright.
But it won't boot into anything else...light is flashing but screen is black.

HELP
I am screwed here.
#1. Tried the "unbrick stock" solution. Can NOT get it to work. I tried it all 3 ways given and it gets to the LG driver start... and then it says I am up to date. I tried to change the country, the language, upgrade recovery, can NOT get it to work.
#2. I can get TWRP to load. But I can't get my computer to recognize my phone so I can move a rom over
#3. I can't get ADB to recognize my phone.
HEEEEEEEEEEEEEEEEEEEEEEELP

save yourself the hassle flash stock 4.4.2 KK, use IORoot25 to root and then use Autorec to install Custom recovery.
Time needed 1 hour.

Restoring stock

Hello, I was stock rooted kit kat, and rooted using ioroot25, installed recovery via AutoRec from Cloudy.
Drivers and everything installed correctly, as the script ran and installed everyone everything successfully.
Now when I'm trying to restore to stock, upon entering download mode, it stays stuck at the firmware update screen at 0%
any advice? thanks.

Read carefully the guides, if I remember well you must disconnect micro usb and press volume - and reconnect the cable. If everything is pk flashing process must start

Help with AT&T LGG2 .. stuck in mud

Problem: Can't boot into OS on my D800. When booting the screen stays at LG logo and LED keeps flashing green and blue.
Hisotry:
1) Had original AT&T D800 not rooted, no recovery. Got OTA upgrade to Lollipop.
2) Got new phone so decide to debloat to give phone to my wife (on T-mobile)
3) Read xda forums. Downgraded to d80010o using LG flash utility. rooted. installed older version of twrp using autorec. now phone won't boot but can get into download/twrp
4) got into firmware download mode and flashed d80010d using lg flash utility. this time copied new twrp on sdcard and stripped version of rom (http://forum.xda-developers.com/att-g2/development/rom-stock-lollipop-30b-stripped-t3144195) along with dorilp kernel
5) went back to twrp. flashed stripped rom and kernal.
Still no dice. Exact same situation. I can get into download mode/twrp but when booting system gets stuck on LG logo with led slowly flashing.
what am I doing wrong ?

Are you able to get into recovery? With a lolipo ROM you have to download KitKat boot stack or simply download blastgator lollipop ROM patch from here http://blastagator.ddns.net

From what I read in the OP of that ROM, you're supposed to just flash the rom zip, boot up, go back into recovery and flash the kernel.
"To install ROM, just flash the zip! (Note: The zip isn't signed.) My zip flashes everything you need for the ROM to work correctly.
Recommended: Flash @dorimanx kernel after install. My zip includes stock 30f kernel."
Maybe that's the problem?

okay.. installed the patch. still no dice. still getting same stuck at LG logo with led flashing.
also dorimanx kernal is installed. still getting the issue. btw i am not married to this ROM. Any AT&T rom will work. I think there is some mismatch of bootloader/kernal/rom and what not.
what things I can check ?

pulling my hair out.
whatever rom I install using twrp it gets stuck on LG logo. i think i see some message about not being able to unmount /system (but rest of install succeeds).
only way I can get back in OS is to use LG flash utility and flash d80010d or d80010o which basically wipes away everything (recovery, root etc).
assuming I am on stock d80010d, can someone please give idiot proof step by step direction (do i need to check modem version/baseband/bootloader/radio/recovery versions or something to make sure it is compatible ?)

Do you have download mode?

yes I do ..

Ok flash back via tot to kitkat and take ota to lollipop. Then use autorec v2. *Do not use the twrp thats comes autorec as it does not flash roms* flash a BUMPED twrp using twrp. Then install your lolipop rom then afterwards install the dormainx d800 lollipop patch just for safe measure but it should work without flashing it.

thanks for suggestion.. but once I take LP OTA, how will i use autorec ? I thought LP can't be rooted and custom recovery can't be flashed.
also all I can find is Autorec not autorec v2.

Yeah it can be rooted. Download stumproot and install it, follow it thru the steps and do the brute force root. Takes a few minutes but it works. I've done it on stock a couple of times. Get autorec v2 on playstore.

i just read that stumproot is not supported anymore..

Actually instead of stumproot, use srk tool to root stock lollipop. I have had success with that.

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.

LG G3 [D855] Custom Recovery And Rom Flashing

I have went through many tutorials but none of them were able to help me with flashing custom recovery(TWRP). My LG G3 D855 was rooted with towelroot(I think long time ago). I do not know how can I unlock my bootloader or I don't know if it is already unlocked(Picked it off craiglist long time ago). Phone is stuck in fastboot mode. I have tried to fix but I could not. There is no 'download mode'.
Could you please explain each and every step in detail? I really want to reboot my device with a custom ROM.
Phone is running Androind 4.4.2.

So guys? Any help? Just tell me how can I remove that fastboot mode that appears when I restart my device for recovery.

Have you flashed TWRP already?
I have a an D855, I don't think you have to worry about a locked bootloader Mate,
but it was a long time since I got rid of the LG crap, because it was the first thing I did after buying new!
You're on 4.4.2 with towel root so it should very simple to download and flash TWRP using the official TWRP app in Playstore or using an app like Flashify etc.
I basically lost my S7 Edge a week ago so I'm back using my old LG G3 now running Resurrection Remix 5.8(Nougat 7.1.2. AOSP based)
If you wanna run anything using Aroma installer then don't go later than TWRP 3.0.0. for now, because the newer versions don't work.
Either download the Quickboot app to boot to recovery or search on Youtube on how to boot to recovery from off..

The problem is, there is no recovery. Even though flashing TWRP via flashify resulted in nothing but an error showing "Fastboot mode started" when I tapped on option named "Reboot to recovery". This is the main problem I am facing. I can flash, upgrade/downgrade and etc but this fastboot mode thing is something beyond what I can fix with my current knowledge.

Maybe first flash back stock, update to the latest firmware and start fresh from there?
There are some good guides in the forums here for that.

If you've to go back to firmware, don't install the newest. Rooting needs an older version. Also described in root-threads here.
