As per the title, I foolishly deleted the boot and aboot. I did this because my phone malfunctioned a few days back suddenly giving a yellow screen after booting. I searched for many solutions but there were none. So I came across with a tutorial which teaches me to delete those file and reinstall via fastboot. I did the delete part but suddenly phone got disconnected and I wasn't able to reinstall the boot images. Now when I plug the USB and tries to switch on, I can feel the vibration but the screen is not coming up. Can someone please help me with a way to restore the phone. Ill make a 40$ donation to the person who will give a solution to recover the phone again .
Only LG has a prayer of fixing it. Without aboot, you can't boot into anything, and it's responsible for fastboot too. Basically never ever touch aboot, and if for some reason you absolutely must, don't delete, just flash a new one over it... Though since chances are you don't have a US996 unlocked through LG you would have at least soft bricked since an engineering aboot is what's responsible for keeping the bootloader unlocked on everything else but the h918
does that include laf too?
Have you tried holing the volume up key and plugging in the usb cable to see if it can boot up directly to laf and then use lg bridge recovery or lg update to flash the kdz for your phone?

Includes laf too. Aboot boots EVERYTHING. He is d o n e bricked and in 9008 mode. For a detailed description of the boot process, see @runningnak3d 's post on how not to brick. He's recently said it's not entirely accurate, but it still gives a good enough overview of the booting process, most relevant:
This time the XBL verifies ABOOT with its own RSA key. If ABOOT is OK, then it loads. At this point, you will have download mode, and at least you can recover (if you have a KDZ). No matter what -- NEVER mess with XBL or ABOOT unless you absolutely want a brick. If ABOOT is corrupt or invalid in some way, then the CPU goes into QD_LOADER (9008) mode.
So now we have ABOOT loaded. ABOOT does a lot of things. Directly, it provides fastboot mode, indirectly, it provides download mode by booting laf. In order to have download, you have to have a working laf. LAF is just a kernel with an initrd that runs lafd (more on that later). ABOOT also allows you to boot recovery. Again, recovery is just a kernel with an initrd.

fastboot bypasses aboot, at least to my knowledge, i have an H910

To fix it, send it back to LG. Not sure where you read that, very bad info

No. In fact aboot provides fastboot as explained in the bit of Runningnak3d's post I quoted above, and that's also why doing dirty Santa which installs an engineering aboot enables fastboot mode, where as the stock aboot for the v20 (except for the h918 and us996) has fastboot disabled.
Do we even know what variant he has?
It doesn't matter what model he has. If you null out xbl or aboot you don't even get QDLOADER (9008) mode. They can be corrupt, or have the wrong RSA sig, or ...... and you will get 9008. If the PBL tries to load them and they don't exist at all it goes into an infinite loop and the only way to fix it is to replace the NAND.

Hello All,
I've been searching for hours. I had rooted my LG G2 weeks ago with no problems. I then un-rooted it and I thought reset it to factory. Today in Target I pulled it out of my pocket to make a call and it was black screened to Fastboot.
I have tried holding down Volume - and Power and entering recovery to reset to factory but it immediately goes to Fastboot loop.
I have tried holding down Volume + while plugging in USB for Download Mode but it immediately goes to Fastboot loop.
I have tried adb commands, error: device not found.
I have tried manually updating the Android drivers through Computer Management and selecting many of the Android Platform Sooner versions. My Win7 PC recognizes the phone as ADB Interface > Andriod Sooner Single ADB Interface in Device Manager.
I have tried this http://forum.xda-developers.com/showthread.php?t=2477595 and flashed both laf.img and I cannot get into Download Mode.
What else can I do? Does anyone have any other ideas?
Thanks for your time!
hey same exact thing just happened to me. i had it rooted from earlier, but ended up keeping the stock rom on my AT&T LG G2 D800. What I think happened was ATT just pushed out an OTA update (not sure about other carriers), supposedly some small 15mb update to prepare for upcoming releases and despite declining the install, the phone of course did it anyways.
No recovery, no download mode, factory reset doesn't do anything.
Thanks AT&T! :good:

If you can't get adb access with either single sooner or pdanet drivers, you may have to resort to this..
http://forum.xda-developers.com/showthread.php?t=2582142
(actually kind of sounds like fun to me)
if you're stuck in fastboot mode then you can simply use the fastboot commands to write the aboot, sbl1, boot, recovery, laf, rpm, tz and dbi partitions.
you can substitute stock recovery.img for a properly patched twrp/cwm img (renamed recovery). from there you should be able to boot into download mode... custom recovery.. or boot back up.

Hello friends to see if I draw from this setback. My situation is that I have no recovery or download, but when trying to get the img fastboot does not exceed by "erasing" or "writing" who knows how to solve this please !!
Thank you :good:
So my VS995 (Verizon LG V20) is stuck in a fastboot loop. I can't do anything outside of fastboot. I got to after step 3 in the Dirty Santa root method and could not get the phone to boot into TWRP recovery. I kept getting an ADB device offline error and could not get ADB to see my device to initiate the "ADB reboot recovery command".
In a stupid and drunk state I did a "fastboot erase system" and thats what locked me into the fastboot loop.
Any help is appreciated as my V20 is now unusable :crying:.
I guess I would need a stock boot image, and stock recovery to get back to where I started. If anyone could point me in the right direction and help me get my phone back (and possibly rooted), I would be more than happy to donate via PayPal .
P.S. The LGUP software used in the how to restore v20 thread linked-> ( https://forum.xda-developers.com/v20/how-to/restore-v20-to-100-stock-bricked-devices-t3524903) does not recognize the model of device giving the error ("you have to select a known model, please")

to my understanding, the kdz file contains the stock boot.img and stock system.img, everything to bring the device completely back to stock .
In fastboot to boot to the system the command is "fastboot reboot"

My phone can not get past FastBoot! :crying: I think I really bricked this thing now. My bootloader is locked, fastboot commands don't work at all.
The only thing that does work is download mode (holding volume up and plugging phone in) and I am able to flash the vs995 firmware from the lg website but i STILL can't boot into anything but fastboot.
Does anyone have any suggestions as to what I can try to fix this thing. I think i'm doomed. I may try to flash the stock us996 firmware because at this point it seems like it wont get any worse.

Did you flash the kdz using Uppercut?
imucarmen - I can't post in the dirty santa thread because I am a new member to XDA (been coming here for years just never made an account )
bond32 - Yes I was able to flash the .kdz using Uppercut+LGUP but my problem is not fixed. My phone still boots right to FastBoot Mode in the "Locked State" to where I can't issue any commands or alter any partitions.
This makes no sense to me if LGUP is able to 100% flash the stock firmware, WHY CAN'T I GET OUT OF FASTBOOT! Lol
Does anyone have any ideas as to what I could try to unbrick this thing?
I know it's a different issue from the one that I had, but the LG Support Tool method that KedarWolf posted might help solve this issue too.

Did you try pulling the battery, put the battery back in.
Hold the volume down and power button at same time. When the lg logo shows up let go of the power button but continue to hold the volume down and press the power button again. It will bring you to a screen tgat has 2 questions. Answer yes to both of them. Then reboot. I believe that resets the way the phone boots almost like resetting a cmos

hold the vol down and power and put in battery as soon as its on click the power button and re hold it. it will get to recovery, it took me hours but its there.
I had tried that a few times after reading about it but I'll try now for an extended period of time and see if I can activate it. I'll report back with what happens, thanks for the tip dwertz and Team DevDigitel
Well I got in to the recovery menu and reset to factory settings and wipe cache (the only two options) but I still am booting right into FastBoot and can't escape!

When you have a unlocked boot loader and you do a factory reset, I believe it wipes the OS from the phone giving you no OS. If you can get back to recovery, flash this rom https://forum.xda-developers.com/v20/development/vs995-vzw-nrd90m-modded-notsostock-rom-t3525864
That will at least get you booted so you can flash the kdz.
I can't get into any kind of recovery to flash a rom though

Same problem here, did you ever fix it?
WARNING
DO NOT LET YOUR PHONE REBOOT, OR POWER OFF UNTIL I TELL YOU THAT IS WHAT YOU NEED TO DO.
If you do, I am not sure what shape your phone will be in.
This should go without saying, but you MUST have your bootloader unlocked (check OEM UNLOCK in developer options AND fastboot oem unlock). If you don't, you will probably brick your phone.
If you use this on any model G6 besides the H872, you will be stuck in a bootloop, and you will not be able to fix it since you will have wiped out download mode!
This is safe if no mistakes are made (typos, missing a step, etc). However, if you do mess up, the risk is high that you lose download mode at best, or brick your phone at worst.
If you deviate from this procedure, and think: "I can just skip a step, or I can do this on my own Linux install". Don't complain if you brick your phone.
PREREQUISITES:
You must have a version of laf that has the COPY opcode.
Since none of the firmware available for the H872 has the COPY opcode, we have to use the H918 laf partition.
Grab the H918 10p KDZ: link to 10p KDZ
You need to be on 11g or above. Be aware, once you are on 11g+ you cannot downgrade to any versions prior to 11g due to anti-rollback.
You will need a copy of the KDZ that your phone is on. If you are not currently on 11g, upgrade before continuing.
For 11g : Link to 11g KDZ
For 11h : Link to 11h KDZ
For 20a : Link to 20a KDZ
We are going to flash this using the patched LG UP. There may be one that was patched specifically for the G6 -- don't use it,
it has NOT been tested. Grab the one for the V20: link
It MUST be installed in: Crogram Files (x86)LG ElectronicsLGUP
You can't just unzip it anywhere and run it, it will not find the model file.
You need the H872 Unofficial 3.2.3 TWRP by @Eliminator74. 3.2.3 is included in the repo so that you know that you have the exact version.
If you decide to use any other version, you will brick your phone because the commands below are for this exact version!
You need to grab FWUL (version 2.7 or later) and burn it to a USB stick: link
Even if you have Linux, and you think you can install the dependencies, don't. I know this works from FWUL.
If you are rooting on 20a, you will need a Micro-SD card. Copy the TWRP 3.2.3 image and the latest Magisk zip to the SD card.
WARNING: Only applies if rooting while on 20a
Minor Encryption-related issues have occurred while testing 20a. If your data partition is encrypted, TWRP will NOT be able to decrypt it. Because of this, you will have to perform a wipe and format of your Data partition. Be sure to backup all data on your device prior to continuing by copying important files to an external SD card or using LG Mobile Switch to back it up.
PROCEDURE PART 1: Getting a working LAF onto your phone
By far this is the most dangerous part of this procedure.
Boot to download mode
In LG UP, choose partition DL.
Pick the H918 10p KDZ
Click start / ok
When you will be given a list of partitions to flash, only check laf
Click start / ok
You will get a warning about additional modified partitions -- ignore it, and click OK.
As a safety feature, LG UP will start flashing those modified partitions after laf completes flashing.
After the flash is initiated, pay close attention to the "step" and as soon as it changes from laf to another partition, PULL THE USB CABLE!
If you let it completely flash the H918 KDZ, your phone WILL reboot, and you WILL have a brick that can't be fixed.
You need to pay attention, but you also don't need to be sitting on pins and needles. You have quite a bit of time to pull the cable since system is one of the partitions that is flashed
Click OK and it will start flashing.
Once laf is flashed, and you have pulled the USB cable, you can click exit, and then re-open LG UP.
Choose partition DL again, and this time pick the H872 KDZ for the version your phone was on prior to flashing 10p (11g, 11h, or 20a)
Select all partitions except laf. If you forget to uncheck laf, you will have to do this all over again.
When it completes, it will reboot your phone.
Go back into download mode. This time you will be running the H918 laf, and we can continue with PART 2
PROCEDURE PART 2: Installing TWRP
Boot from your FWUL USB stick.
Put your phone into download mode. With the phone powered off, hold vol up and plug in the USB cable. You do not need to touch the power button -- the phone will power on and enter download mode.
This will NOT look like normal download mode on the phone. All you will get is small box that says: "Download mode" -- this is normal. You will also not have ANY indication on the PHONE that it is being flashed.
Once booted, login. The password is: linux
Double click the LG folder that is on the desktop
Double click on LG LAF (runningnak3d) icon and you will be at a terminal prompt.
The following are the commands that you enter into that terminal. You can copy / paste them if you like.
Code:
git pull
git checkout h872-miscwrte
./step1.sh
When you are told to, pull the USB cable, and the phone will power off. You now have TWRP on your laf partition. At this point you can flash a ROM, or Magisk or whatever you like, but I would suggest
at least flashing TWRP to the recovery partition. There is no button combination to get into laf (download mode), so if you only have TWRP on laf, then you will need a USB cable to get into recovery.
OPTIONAL:
If you don't know what to do with TWRP, and you just want to run rooted stock 11g, 11h or 20a, this is for you....
First boot into TWRP - with the phone off, hold vol up and plug in the USB cable.
PROCEDURE PART 3: Rooting and cleanup
Now that you are in TWRP:
Nougat (11g, 11h Users)
./step2.sh
If you ran step2.sh you have TWRP on laf, and recovery, and you are rooted. If you only ran step1.sh, then you have TWRP on laf. Either way, enjoy!
Oreo (20a) Users
Once in TWRP, click the “Wipe” button.
Choose Advanced Wipe and select the Dalvik, Data and Cache options and Wipe. Do not reboot the phone.
Go back to the main menu or main wipe screen
Select “Format Data” and complete the format.
Go back to the main menu and choose Install, and then Install Image.
Flash the TWRP 3.2.3 image from external_sd to the RECOVERY partition. DO NOT Reboot to System.
Go back to the main screen and attempt to reboot to Recovery.
If you are able to reboot to recovery without any issues, you should now Install the Magisk zip from external_sd.
After flashing Magisk, you may now reboot to system and Oreo should boot to the initial Android Setup screen.
After booting to Oreo, make sure you enable installations from Unknown Sources in your Android Settings and install the latest Magisk Manager.
If Oreo boots to an "Encryption Unsuccessful" screen, you will need to format the Data partition again. Tap the reset button and it should boot to Recovery. Perform another wipe of cache/data/dalvik and go back to the Wipe screen and Format Data. Reboot system and you should boot to Oreo Normally.
To Restore Download Mode
20a - Flash @Eliminator74's Bootstock with LAF image using TWRP
11g - Flash @weakNPCdotCom's StockLAF image using TWRP

You ARE the man!
Good job, I'm certainly tempted to try, but have never done such kind of procedure to get root and I started flashing and rooting some time ago but everything was easier back then, I'll probably wait a bit, what's a week or two when I got the phone May last year.
Enjoy your time off. You really deserve it.

it my fall, when i start to do laf partion i didn't see when come out laf partition, so i let the program do his job after i see that it come to system write and i understand that it was there that i will pull the cable out, btw i will wait some good person will found solution for the qualcomm 9008 problem..they made a lot of good job..and of course is my mistake...if someone know how to come out from this problem i will be grated for all life..for the moment i will wait..or i found someone can unlock for a good price i will pay him and do the job...
The only fix for 9008 mode on UFS devices (which the G6 is) is a firehose programmer and QFIL. It is no longer possible to boot from an SD card. AFAIK, there is no signed (yes it MUST be signed) firehose for the H872.
Your only options are T-Mobile or LG warranty, or pay to have it repaired if it isn't under warranty. You could also swap the board with an H872 that has a cracked screen, but getting the thing apart looks like a real PITA.

Guys i found this on the web... maybe for the profesional user this can be a way to unbrick lg g6 with hard brick like mine https://www.androidbrick.com/download/download-latest-2018-qualcomm-flasher-qfil-qpst-2-7-472/
i try to use it and i didn't understand nothing..but my mobile it see as download mode
Thanks for putting this together, runningnak3d!
So, reading through the tutorial, you say this towards the end, after doing the cleanup steps:
Now you have TWRP on laf, and recovery, and you are rooted.

So... does that mean attempting to boot into LAF will always put you into TWRP? If yes... is there any way to get the original LAF partition back, while keeping TWRP in recovery?

Yes, you can extract it from the 11g KDZ and flash it, but why? There will never be a situation where you would want laf over TWRP.

My main reason is to maintain multiple methods of recovery. With a working LAF, you can flash a KDZ to get back to a working phone (even though it would need to be re-rooted). With TWRP in the LAF partition, if for some reason both instances of TWRP failed, that is no longer possible.
If something stopped TWRP from booting on laf, then laf wouldn't boot on laf either. They are both just kernel / initrd boot images.
Do what you want, but trust me, you are a lot safer with two copies of TWRP.

Generally, I'd agree. Having redundant TWRP recoveries is probably better.
But it is nice that we can restore LAF on the off chance we want to restore the phone to default via KDZ. Perhaps to sell it or such.

Anyway, thanks for all the great work! I'll probably give it a whirl in a few days. Hopefully, this will spur some ROM development for the H872.
I made it all the way through to mounting system with read/write, twrp console just complains that it failed to mount /system with "device or resource busy". I haven't attempted to boot into recovery again since booting into system but twrp is definitely on laf still. I did try booting from laf twrp to recovery twrp before booting to system and it didn't have permissions either.
Installing Magisk doesn't give me root as it spits an error can't write to /system.
I truly never thought I'd ever see TWRP on this device, this is incredible.

U can mount /system. If u still have twrp on the laf partition all u have to do is reboot twice back into twrp then go to mounts and check system, clear cache then flash the magisk zip. But one thing o truly hate about magisk is my frequencies don't stick on kernel apps so I flashed regular su and right now everything is running amazing.

Also if anyone has got a bootloop after flashing something I found out that the phone reboots when you are restoring backup. To fix this flash recovery system and boot from the backup but u have to keep tapping on the screen so it dont timeout and restore wrong.
Think I will wait till next week I'm just happy you got this far
One of my costumer V20 is now stuck in fastboot.
Whatever I do, it's keep coming back to fastboot mode.
I can enter download mode, and try flash , even using the costum LG up, with upgrade option, partition DL option.
I use Box ( octopus, Z3x ).
I don't know what is wrong with this phone.
it's only going back to fastboot.
Any help is really apreciated.
Thank You.

What does using the "fastboot reboot" cmd do ?

It goes back straight to fastboot after LG logo
If you can get into download mode try the 'upgrade' option in lgup
It is stuck in fastboot because your customer tried to root it with lafsploit without unlocking the bootloader.
They have two choices:
1 - Send it to LG to have it repaired.
2 - Wait for me to finish lafsploit 2.0 which will unlock their bootloader, and their phone will just start working.
The partitions that hold the unlock information are not touched when you flash a KDZ, so no amount of flashing is going to fix it.

I think that's what happen, and I don't have any choice except to wait . Returning to LG is not an option.
Thank you very much sir.

If you cant get into download mode by powering off, holding vol up and then plugging into a pc (no power button needed) then you dont have a phone anymore. Unless rooted via dirtysanta which replaces aboot (which provides fastboot), the stock fastboot mode of the h918 can't actually flash anything to the phone which means no unbricking with it; TWRP and download mode are only ways to restore firmware.
I know this is an old thread but my gf has the h918 which is unlocked with twrp Installed, she tried updating magisk from inside magisk and now she's stuck in fastboot mode .The fastboot reboot command does not reboot the phone I even booted into twrp and wiped cache any ideas?

This is a Magisk 20.2 issue there's at two threads in the LGV20 forum on how to recover
Sent from my LG-H910 using XDA Labs
I had a fully functioning V35 AWM with Magisk and TWRP on the V350ULM20e image. I installed DriveDroid and forced a kinda soft bootloop. I tried to enter TWRP with the buttons but couldn't, so I backed up and re-flashed abl_a with the V35 eng image to get fastboot to reboot into TWRP. Only problem is, reboot recovery rebooted it normally. I then reflashed abl_a back to my backup and rebooted only to find the fastboot screen again. So I tried re-flashing boot_a, boot_b, abl_a, and abl_b back to their original backed up 20e images and I erased laf_a and laf_b. Still stuck on fastboot screen and need help! I can't even get into download mode and fastboot mode doesn't have an option for recovery anymore. (This is also my first thread on XDA, if this is in the wrong place, please instruct me on where to put it )
I managed to get into download mode after a lot of tries. Flashed 20e kdz. Phone back to working (no TWRP or Magisk). Getting some sleep now.
Advice for anyone with a similar issue: keep trying different button combinations until you get download mode, I have found that if you have the stock abl_a, abl b, boot_a and boot_b, then download mode is almost guaranteed to work.

I'm sure all that was frustrating for you, but lets try to clarify it, especially so others can have the correct information.
You say if you have the stock abl and boot, download mode is almost guaranteed to work Which is pretty humorous as it's the laf partitions that are used in download mode And it's not 'almost' guaranteed, it's 100% guaranteed, with the correct original partitions
And you don't have to flail around trying a kazillion button combinations, as there is 1 combination that will always work; press and hold vol up while plugging into usb port. Boom. It works. Every time.
If that doesn't work, then the partitions are wrong, not the key combination you're using. So here's the situation with the partitions: The engineering abl can be used to get fastboot access, as known. You can get into fastboot with that partition directly after flashing it with EDL (qfil), even if you are on Pie. But you can not leave it there if you want to BOOT Pie, as it's an Oreo partition, and it won't boot unless it's Oreo.
Another way to get fastboot (although it seems to be a somewhat 'crippled' version of fastboot), would be to erase the laf partition (don't touch abl). This would give you fastboot but you would get to it the way you would normally get do download mode (remember download is the laf partition), because laf isn't there, you'll get a version of fastboot instead.
But if you use the 2nd method to get fastboot, (deleted laf), that means if you want to use download mode (lgup), you have to flash the original laf back first.
Hey, it's all fun and we're all learning some new things. I hope this helps to make it a little clearer. Cheers

Wow, thank you! That actually clears things up a lot for me (and hopefully other people ) I am now restoring a backup of my UserData with TWRP and working my way around a lot of little issues, learning about stuff the whole way through. I hope to eventually get LineageOS working on this as I really liked it on the switch (hey, it works on the V40...), but that is going to take a lot longer to figure out :fingers-crossed:. Have a good one!
