It works on android 11.
[LG G8 Guides, News, & Discussion] ClownWorld:
@AsItLies I did a search on lgunlock but only found a user called lgunlocking, not sure if this is the same, when you did the unlocking. how was it done, did you also have the sim code popup so all you neeeded was for him to provide a code or did you not and had to plug in via usb and then he had to do something through teamviewer vnc?
[LG G8 Guides, News, & Discussion] AsItLies:
In my case they had to use teamviewer / usb /octoplus etc. It would be much easier with a code, but I didn't get any pop up with the oem Sprint rom.

I'd try the code unlocking first personally for sure, since you say you get that pop up currently. Maybe search ebay and go with the one that has the best feedback. See if they give refunds if it doesn't work?
[LG G8 Guides, News, & Discussion] ClownWorld:
I asked one, he said in broken English that he doesn't do that, for some reason. Did not motivate. I found the guy on tg, his handle is unlocklg
[LG G8 Guides, News, & Discussion] ClownWorld:
The sites which claim to provide free unlock codes if you enter imei number, they're email phishing spam sites or something like this, maybe they want to do something with the imei, scams, right?

Is it dangerous to input in IMEI into these sites?

Does this method work on the factory unlocked LMG820QM7? I have Android 11, and I tried QFIL with the SM8150 firehose, and I got fails any time it got to the point to reset EDL after closing the partition manager.

I tried rebooting the device manually, and the touchscreen didn't work anymore. I managed to do a factory reset, and it's working again, but I still want to unlock the bootloader and root.

Thanks,

Josh
[LG G8 Guides, News, & Discussion] AsItLies:
It should work. You don't go into much detail about how you're trying to reset the device, etc. So generic responses only:

don't use a usb 3.0 port, qfil only works reliably with 2.0

to exit qfil be sure to hold vol minus and pwr button until you hear windows chime.

check device manager with device connected to be sure it's recognized properly, if it's not, you have to load the appropriate driver.

It would really be easier for you if you did this: 1) explain **exactly** what you did. 2) explain **exactly** what the results were, assuming they are not what you expected.
[LG G8 Guides, News, & Discussion] joshdv:
Device confirmed in Device Manager. Followed instructions, everything appeared to work following the instructions.

I could use partition manager (to back up or load abl_a/_b etc.), and after clicking OK, for the part "Your phone will reboot to EDL on its own after pressing OK." I get failure messages.

I think I was on USB 3, but I'd be surprised if that's why it failed. I'll try again and see if that changes anything.

Thanks,

Josh
[LG G8 Guides, News, & Discussion] AsItLies:
Well, one thing to be aware of, whether it's this guide, or really any guide on xda, they are written by users just like you and me.

They are not written by LG, or Google, or any technical company. That's why, any guide I follow, the first thing I do, before anything, is read the comments people have already made about the guide. What issues are there? Anything obviously wrong? etc.

To get out of edl, it's as I say, vol minus puls pwr, for about 5 sec, until u hear windows chime. And no, usb 3 speeds are just too fast for old qfil sftware, usually resulting in corrupted backups or something you upload. You won't know it, probably no error, but it simply won't work.

highly recommend, read the comments in a guide before doing anything, even if you just skim them.

cheers
[LG G8 Guides, News, & Discussion] joshdv:
lol, I did. But there's 37 pages, so it's pretty easy to miss a few things. 😉

I'll try on the USB 2.0 port when I have time to mess with my phone again. I'm not worried about bricking it, I'm not opposed to having an excuse to buy something new.
[LG G8 Guides, News, & Discussion] joshdv:
I'm bootloader unlocked and rooted now. USB 2.0 was definitely necessary for EDL to work properly.

The key with my phone was getting into fastboot was a PITA. There was no way to power down the phone without the touchscreen working. The way I finally got fastboot to load was by leaving the USB cable plugged in, and holding power & vol -, then quickly letting go of power. Without the USB cord plugged in, I simply couldn't get to fastboot.

Once in fastboot, I had to manually install the LGE android ADB driver for fastboot to work with the phone.

Thanks,

Josh
[LG G8 Guides, News, & Discussion] kllax31:
hey bro, my LG V50 is boot-looped and I've accessed the fastboot mode. My problem is when I do OEM unlock, it fails. how do I fix this? I cant access the developer options also as it is boot-looped. any help would be much appreciated.
[LG G8 Guides, News, & Discussion] AsItLies:
Why is it bootlooping? what did u do to cause that? You can't access dev options does that mean oem unlocking isn't on? What does it tell you when it fails trying to unlock?
[LG G8 Guides, News, & Discussion] kllax31:
Its probably bootlooping because I've been using this as my daily driver and I have alot of 4K videos on this phone. I think the storage capacity got way too full and couldn't handle the background tasks that is mainly running the phone which caused it to bootloop. It began overheating, constant freezing, and I just can't even get past my lockscreen as it would just restart. Even charging the phone wouldn't help, it would just restart until it would ran out of battery. I haven't tried anything that would cause this like rooting the phone or flashing a new ROM because I have no experience on anything like that. I would just like to get my phone back to stock and get it running again. I tried to do a factory reset with the power and vol+ button and after a few seconds it failed and began bootlooping again.

I can access EDL and have managed to get to fastboot by following this guide to unlocking bootloader https://xdaforums.com/t/guide-lg-g8...nlock-and-magisk-root-using-firehose.4221793/

But this is where I am stuck at right now

I have accessed the fastboot but the bootloader is locked, and I have tried to do the OEM unlock command on ADB but it says FAILED. It's probably because I haven't turned on the OEM unlock option in the developer options. I'm really stuck right now any help would be much appreciated.. thanks.
[LG G8 Guides, News, & Discussion] AsItLies:
Well it sounds like kind of a mess. I'd suggest, assuming you have a device that has the kdz available for it, get the kdz and partially follow the guide for crossflashing OPID mismatch. You wouldn't be crossflashing, so you wouldn't have to do all the partition deleting etc, you just want to get lgup from that thread and use your original version kdz.

cheers

Is there any way to install twrp on sprint android 10 lg g8 thinq without rooting?
[LG G8 Guides, News, & Discussion] AsItLies:
You would have to get the boot image with twrp injected and flash it with qfil. But why would you want to? if you don't have root / magisk?
[LG G8 Guides, News, & Discussion] ratman_04:
Hi, in this part I am confused. Should I create 2 files of the highlighted file in the first image then rename it as abl_a.bin and abl_b.bin respectfully?

View attachment 5618519

Thanks
[LG G8 Guides, News, & Discussion] kt-Froggy:
You should read and save (backup) BOTH files. They are different. Read abl_a first in Partition Manager, then rename the long filename to abl_a.bin. Then read abl_b and rename the resulting file to abl_b.bin.

After you are done with the BL unlock, you will have to restore both of them to their respective partitions.

I just followed this guide exactly, and everything worked.
[LG G8 Guides, News, & Discussion] kllax31:
hey man, I've tried the guide for crossflashing OPID mismatch and followed everything. I've managed to get into download mode by using QFIL and deleting partitions. once i was inside download mode I tried flashing an old stock stock rom kdz (android 9) because the android 11 kdz (didn't work it would just keep on restarting on the LG logo). on Android 9, i actually reached the setup area where you choose language and all that. but the problem still persists where my phone keeps restarting and overheating..
[LG G8 Guides, News, & Discussion] AsItLies:
that sounds like a hardware problem.
[LG G8 Guides, News, & Discussion] DerkWehler:
I have a brand new V50 Verizon phone, V450VM, with software version 20i, which was advertised os being unlocked. When I try to follow the directions in this thread though, my settings screen has no "Enable OEM unlock" slider. I thought maybe this was because there was no SIM in the phone, so I put one in, but nothing changed.

And ideas why it's missing on mine? (see attached screenshot)
[LG G8 Guides, News, & Discussion] kllax31:
Im not sure if its the battery because i've tried it on Download mode where I waited and see if it would restart but no, it only tends to restart once i've booted it up to the setup area, I think it's an software problem
[LG G8 Guides, News, & Discussion] deckstar:
Hey,

LG G8s (upgraded to android 10 for this tutorial) user is stuck on

"

Once your phone is in Fastboot it should say

Device State: Locked and Active A/B Slot - _a or _b

remember whichever slot your device says and stay on that slot, you may risk bricking if you change to the other slot. You also need this for Root later.

"

My LG G8s doenst shows the Lock State in fastboot! i can only see number 1. 2. 3. and can restart oder poweroff the phone

also the fastboot oem unlock doesnt work - "command failed"

"fastboot devices" says

"LMG810EAW1608d798 fastboot"

oem unlock in delevoper mode is activated

thankful for every help!
[LG G8 Guides, News, & Discussion] porakero:

I am now in fastboot mode as shown in the picture yet fastboot devices won't show any devices connected. Am I missing something? drivers?

Please help. Thanks

[LG G8 Guides, News, & Discussion] q-killer:
Care to elaborate on how to do this? Is it

fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img

Prior to flashing magisk patched boot?
[LG G8 Guides, News, & Discussion] AsItLies:
Yes, that's the command to use. You can verify the spelling is accurate by this: fastboot --help

It will give you a list of all the commands ans spelling ans syntax.

You can do it prior flashing patched boot image or after, doesn't matter, they are unrelated.
[LG G8 Guides, News, & Discussion] kt-Froggy:
I am assuming you are running Windows on your PC - are you? You may be missing a driver... That was my problem when my laptop couldn't see the phone in fastboot mode. In my case, after I installed the LG Windows driver package, Windows still failed to apply the driver to the device because of the untrusted/unverified publisher. When your phone is connected in fastboot mode, go to the Device Manager, and look for any problem devices. You may see an entry called "Android device" or something like that, with a yellow exclamation sign. If you do, you will have to manually update the driver for it, pointing to the driver's installation directory. This immediately fixed the problem for me, and the phone was recognized properly.

hello mates

i have an lg g6, will this method work with it?

i'm thinking on doing this process but i don't know if the abl partition would be compatible with my phone.
[LG G8 Guides, News, & Discussion] AsItLies:
Not only would the abl partition be incompatible, the programmers firehose needed for qfil would be incompatible.
[LG G8 Guides, News, & Discussion] amstrak:
HI, can you share where i can find that guide, seems i cannot find it in this forum.

i can only find this for lg g8x, mine is g8 thinq verizon.

in this you have to flash dm_verity zip.
[LG G8 Guides, News, & Discussion] q-killer:
So... I've followed this guide twice now. Both times my sprint v50 was bricked. After paying for a recovery service ... I tried again then after booting into twrp and flashing magisk the second time and then formatting, it stays at the LG logo and bootloops. WTF am I missing!?!? Please help! I want to restore root!

When I boot back to EDL then using QFIL I replace boot_a with the stock backed up, the phone then boots. but when boot_a is replaced with magisk patched image, even canary, it hangs. Why!?! When I boot to recovery, it's now the STOCK recovery; therefore TWRP was never installed permanently as magisk claimed, despite installing it via the zip method in magisk as described. When I rebooted to recovery initially the first time, I was able to boot to TWRP, I reinstalled magisk.zip and a flashed zip with dmverity... but it bootloops, so WHY DID MAGISK LIE? it apparently didn't do anything except soft brick my device, as the patched images will no longer boot. How about coming up with a removal method magisk?!? or a way to figure out what the hell the software did?

It's strange the phone boots and acts like it's stock, but apparently not, Magisk did *SOMETHING* when I flashed twrp ab us zip for this phone and verity but WHAT?!? and how can it be undone? This is infuriating! If it was documented what magisk changes *somewhere* perhaps it could be reversed or retried, but wtf! I know I'm not the only one with this issue!!
[LG G8 Guides, News, & Discussion] ManoharMaddineni:
any luck with this? been looking all over. nothing that is positive, between LG shutting down its unlock service to not open-sourcing the firmware before the shutdown, it's all destructive corporate nonsense
[LG G8 Guides, News, & Discussion] vdbhb59:
Nope, none at all. The dev team does not even reply, nor do they bother anymore. Anyways, I am gonna use it till I can, and then move out. BTW, I have disabled almost everything, I could.
[LG G8 Guides, News, & Discussion] ManoharMaddineni:
I did not understand
[LG G8 Guides, News, & Discussion] vdbhb59:
What I meant was: Since, I cannot unlock bootloader and root my Wing, so I disabled and uninstalled via ADB as many application/services as I could.
[LG G8 Guides, News, & Discussion] ManoharMaddineni:
Interesting. I'm sorry if I keep bothering you, but, could you tell me the list and what the exact advantage of disabling said services and/or apps is?
[LG G8 Guides, News, & Discussion] vdbhb59:
Gimme few days time mate. Will need to make some time pls. :)
[LG G8 Guides, News, & Discussion] porakero:

How to fix it
[LG G8 Guides, News, & Discussion] SnappyCrunch:
Success!

I have a G8 (LM-G820TM, US T-Mobile variant) that had been updated OTA to Android 11 (G820TM30b). I used Windows 10 Pro 64-bit, version 21H2, on a Dell Latitude E6230 (That shouldn't matter, but is provided for reference).

Some notes for anyone else doing this, and wisdom I got from more experienced commenters in this thread:

Read all the instructions carefully. Read every word slowly. Do what you need to do to make sure you don't skip any steps. If necessary, print out the instructions and cross them off one by one.

EDL Mode doesn't show anything on the screen. You'll only know if your phone is in EDL mode if your computer makes a USB Connected chime, and it shows up under Ports in Device Manager.

Use a good quality USB 2.0 cable and USB 2.0 port. QFIL is finicky, and doesn't like USB 3 ports. If you get a Sahara error, use a different cable, a different port, or a different computer.

When you back up your abl_a and abl_b partitions, they should be about 1MB. (1024KB exactly, in my case). If they're significantly larger, then they didn't read correctly. You'll need to flash them back later, and if they didn't read correctly, you can't restore them.

The provided engineering abl_a should be flashed to abl_a and abl_b.

The engineering abl should only be used to enable fastboot temporarily so that you can unlock the bootloader. You can't leave it there - you have to flash your original abl_a and abl_b back to your phone once the bootloader is unlocked. If you leave the engineering abl on there, you'll either get a bootloop or your touchscreen won't work.

When booting into fastboot for the first time, Windows doesn't use the correct (or any) driver, so the phone just shows up as "Android" in Device Manager, and it doesn't show up when you do "fastboot devices". I had the LG Mobile Driver installed per the instructions, so it was just a matter of pointing Windows at the correct driver. In Windows 10 it was Update Drivers -> Browse my computer for drivers -> Let me pick from a list of available drivers on my computer -> Android -> LGE Mobile ADB Interface
[LG G8 Guides, News, & Discussion] Kev_r22:
I recently updated my device to Android 12 and tried this method, I managed to unlock the Bootloader but I can't install magisk.

I already tried everything, I patched the boot_a and boot_b files but they don't work, just magisk doesn't load on the phone system, what do you recommend?
[LG G8 Guides, News, & Discussion] AsItLies:
Did you install the Magisk apk? Many times magisk doesn't 'show up' unless the manager is installed, even though it's there.
[LG G8 Guides, News, & Discussion] Kev_r22:
I tried several times and nothing works, magisk how application if it is installed but nothing extra is active
[LG G8 Guides, News, & Discussion] brokemyphoneagain:
Hi

So I know I'm an idiot, but I pressed the wrong button when backing up the abl partitions and it didn't actually make a backup image of them. So now my phone can't use touch, I can't get into download mode to use LGUP to revert to a good image (assuming that would even work), and basically I'm screwed.

Again, fully aware that it's my fault for being a dummy, but I have to ask: is it *at all* possible to find a known-working image of the abl partitions? Would it even work to transfer from one phone to another?

LG-G820UM, Verizon, last running Android 10
[LG G8 Guides, News, & Discussion] AsItLies:
The abl's in this link should work. They are from sprint device but same android version. Pretty sure they will work but just in case, be careful everything you do so you can revert back if necessary.

and, btw, those are the files you would need to flash all if you want to get lg-up to recognize the phone and reflash kdz.

cheers
[LG G8 Guides, News, & Discussion] br@inmatr:
Good evening.

I've gotten to the part it's time to use fastboot mode to inject the files, but reached a brick wall (not a bricked device lol). When I enter a command prompt to "search for devices", I get error messages saying it's not the correct entry. I know I'm missing a step somewhere, even though I've followed it to the letter thus far. I'll keep searching this forum for clues, but can use any tidbits of info to steer me in the right direction.

Thanks in advance.
[LG G8 Guides, News, & Discussion] AsItLies:
Two things... one, please don't quote the entire first post, just to make a comment about an issue yer having. Tremendously needless waste of space.

Second, what command are u entering? Your comment doesn't specify what yer doing, only the results, how can anyone possibly know?

**IF** you're entering 'fastboot devices', and getting nothing, look in device manager and find the entry with 'Android !' and load the adb driver for that entry.
[LG G8 Guides, News, & Discussion] br@inmatr:
Thank you for that info.

Hi, Thank you for the tutorial. I have rooted my phone once. My phone is v50 sprint. I follow another tutorial to remove sprint's bloatware and bootup animation.

I've use magisk to flash twrp (and lost root), then twrp some how cannot mount my storage so I cannot flash anything.

I decided to go back qfil to flash magisk back but after flash magisk image I've got bootloop.

I went back to qfil and flashed stock boot_a.bin. then I can boot but there is something strange. the sprint's boot animation disappeared, my phone show LG's boot animation.

Now i can totaly using my phone but I cannot root it one more time. follow the button combine to fastboot will direct me to the recovery (image 2: something like this, this is not my phone, I downloaded this image from internet)

I've tried to patch my boot_a.bin again using magisk manager but still get bootloop.

I have lost my fastboot menu, is there anyway can I get it back?
