Just flash the entire 20d backup (all partitions) onto slot a from the engineering fastboot in slot b
[LG G8 Guides, News, & Discussion] Crows12:
Is there a place where I can get the entire 20d backup. The sprint g8 files that are linked dont have it just the magisk patched boot images?
[LG G8 Guides, News, & Discussion] brigantti:
Is on the guide the link for the download i believe is close to 7gb

Here is the link

[LG G8 Guides, News, & Discussion] Crows12:
Thanks I found it. Should I flash the regular boot_a.img or the patched boot image considering I dont even have twrp anymore?
[LG G8 Guides, News, & Discussion] Malezar:
So I got a cheap G8 unlocked on Ebay. Model LM-G820QM. I gave the official unlock bootloader site a shot, but got the message it wasnt supported.

It runs this firmware LMG820AT-00-V20a-LAO-COM-JAN-09-2020-ARB00+5 , which seems to indicate its on Verizon code and I got temp root and Magisk installed without issues.

Now the question is, what are the differences between this model and the pure Sprint one and if it will brick if I attempt the bootloader unlock.

Any ideas?
[LG G8 Guides, News, & Discussion] brigantti:
You need specific files for your device.the files on this tutorial are for the sprint variant only.you can ask on telegram if the files for your device are available.
[LG G8 Guides, News, & Discussion] mr.vishh:
i bought an lg g8 sprint from ebay,which is locked and now I'm in United Arab Emirates, sim is not working and ended up using the wifi only,by unlocking the bootloader will it allows me to unlock the network to use the sim here? model is LM-G820UM and software version G820U20a.

I tried to follow the steps to unlock the boot loader and found some steps difficult to understand, like switching the slots,twrp, getting boot images and all i didn't understand, do you have an easy uncomplicated explanation to unlock it or if you can simplify the steps will be a great help, thanks in advance.

TMobile G820TM unlock stuff

The files needed to unlock

https://www.androidfilehost.com/?fid=8889791610682884889

I updated the Sprint unlock files from the main post to have the TMobile files needed to unlock under the 20D January 2020 Android 10 firmware. If you are not on that firmware especially due to being updated to the April 2020 Android 10 firmware you will need to downgrade to January 2020 as April 2020 has the exploit we are using patched. You can use the PDF guide from the main post as that pretty much covers bootloader unlocking the TMobile G8 in terms of each step very well.

The KDZ for January 2020 is here towards the bottom of the page:

https://lg-firmwares.com/lg-lmg820tm-firmwares/

And here's the software you will need to get the job done:

https://www.androidfilehost.com/?fid=8889791610682884898

1. Install the LG drivers if you haven't already.

http://tool.lime.gdms.lge.com/dn/downloader.dev?fileKey=UW00120120425

2. Install LG Up

3. Install the LG Common DLL

4. Copy the UI confilg files to C:\Program Files (x86)\LG Electronics\LGUP\model\Common

5. Turn off the G8.

6. Once off hold up volume up then insert your USB into the phone.

7. Open LG Up. If you get an error message ignore.

8. Select REFURBISH in LG Up

9. Load the KDZ file by drag and drop where it says BIN file

10. Click start

11. Once the downgrade is done installing the phone will reboot. I highly recommend not putting the phone on Wifi and turning off data to avoid any chances of the phone updating.

Thanks to the many people in the Telegram chat for all the help I've gotten in unlocking the TMobile G8.

You can't sim unlock with bootloader unlock. You can only do it through sprint
[LG G8 Guides, News, & Discussion] mr.vishh:
Thank you for replying,so unlocking the bootloader will not sim unlock? no other option other than to unlock through sprint? i bought it from ebay and that seller didn't send the sprint sim, i had contacted sprint customer online and they told they can't or you are not eligible for unlocking. and when I posted the same in sprint community, they banned me and when i try to login, it shows foreign unlock,you are banned.

G8 G820QM Bootloader/Root Files:

https://www.androidfilehost.com/?fid=8889791610682885339

Like with the T-Mobile ones I provided this is based off the Sprint one used in the first post but with the needed files pulled from the G820QM KDZ's to achieve bootloader unlock and root. Thanks to [MENTION=1027678]Malezar[/MENTION] for testing and confirming this works. Use the PDF in the first post. Slot A has Pie while Slot B is Android 10 on this variant according to Malezar. Still do follow the guide as far as checking to see which slot is which on your G8 you never know how your device is configured until you check.

Stuck in fastboot mode

Thank you so much for your contribution and giving us the appropriate T-Mobile files. However, while my bootloader is unlocked, I'm currently stuck in the fastboot. My 20d was in slot A, so I got temp root and switched the .img files in slot B, switched back to slot A to unlock the bootloader. However, whenever the device boots, it goes straight to fastboot and I can't exit it without reflashing the kdz file with LGUP. After doing that, the phone says the bootloader is unlocked, but I can't flash magisk or twrp. Did I miss a step?
[LG G8 Guides, News, & Discussion] antintin:
Lol that's not how slots work. Everyone needs to see for themselves
[LG G8 Guides, News, & Discussion] TheLoonyRebel:
Yep that's why I still recommend checking which slot is which at that step. I'll fix my previous post to reflect that.

---------- Post added at 07:57 AM ---------- Previous post was at 07:52 AM ----------

You have to install TWRP via Magisk as it says in the PDF to do. So install the Magisk Manager apk then use modular to flash the TWRP ZIP. Then follow the instructions on what to do in TWRP.
[LG G8 Guides, News, & Discussion] AZN2000:
Yes. However I'm stuck in fastboot at 4A. I can't download Magisk Manager to install TWRP to then install Magisk. Should I try following the 4B using the kdz file?

New lg user asking for help. Thank you

Hello new lg g8 sprint user here. Can i get/install android 10 update with this method? Please elaborate me if anyone can. Thank you very much ?
[LG G8 Guides, News, & Discussion] Malezar:
I ran into the same issue on one of my slots. Here is what I did and worked. Be careful though.

Boot to slot A.

Install 10 from the KDZ via the LGUP tool.

Boot to slot B

Install PIE from the KDZ via LGUP tool.

Boot to slot A

Start over from step 2.

In addition to that, I actually locked the BL and started from the beginning.
[LG G8 Guides, News, & Discussion] AZN2000:
Ah that makes sense. Thank you very much. I'll test that out
[LG G8 Guides, News, & Discussion] AZN2000:
Thanks again for the tip. But unfortunately, I wasn't able to install both 10 and pie. I tried booting into each slot and flashed the appropriate firmware file using LGUP Refurbish option. That didn't work. I saw something online about Partition DL to flash it directly into a slot, but Im not too familiar with the partitions of Android systems because I couldn't find a clear guide on cross flashing using LG UP.

Thank you again for the help, but I guess I'll leave my device unrooted for now.

AT&T Branded LM-G820UM?

Why is this method only applicable to the Sprint phone? Also wondering if it can be possibly adapted to LM-G820UM. I bought one by accidently thinking it had a bootloader which could be unlocked...
[LG G8 Guides, News, & Discussion] antintin:
Yeah... Give me till tomorrow and I'll upload instructions and files for Canadian, us open, Verizon, t mobile, at&t, and Korean (tell me if I'm forgetting something please lol). And by the way, all those except for us open and Korean variants are g820ums, so it would be helpful if you could be a bit more specific.
[LG G8 Guides, News, & Discussion] bodhisattvah:
Hey, looking at this and not sure how to read the version--I've got "G820UM10h".

Safe to say that 10h is lower than 20f?
[LG G8 Guides, News, & Discussion] antintin:
Yeah lol it's not even Android 10. But you need to be able to update to Android 10 to do this in the first place. Are you sure yours is a sprint model?
[LG G8 Guides, News, & Discussion] bodhisattvah:
It's not! It's Verizon. But you said in the previous post you might have the files to do the V? And is 10 not out for the Verizon yet? And TIA either way!

EDIT: well, I just got the phone yesterday and decided to fire it up and it wants to update to 10, so 10 does exist for Verizon. Now to stop it from updating while I sort things out...
[LG G8 Guides, News, & Discussion] antintin:
Yeah stop it from updating for now. I should have time today or tomorrow to publish all the files now that it's the weekend

How do I know if my LG G8 is Sprint specific when the model # is LM-G820UM? It boots as Sprint and when I first bought it off eBay I used adb to remove all the sprint bloat. I'm also on software version G820U21a. Any chance that I can still BL unlock and use the volte fix since T-Mobile is going to VOLTE only come January?
[LG G8 Guides, News, & Discussion] antintin:
No, but there will be another root method eventually. Also, t mobile will just shut down all 3g networks, so you'll still be able to call with hspa+

sh backupall-part.sh crashing phone

Hey people, I am at step 2. Have temp root, works fine sometimes, but is super unstable. (su, get it?)

I am running on G820UMd canadian carrier and so far so good, except this command.

sh backupall-part.sh

Every time i run it, it crashes the phone after the first 6 files get backed up. (ie, reboots it) Is there another solution to complete the backup of files by choosing them individually? I see the backupselected.sh file, but am unsure of how to use it.

Another thing to mention, I did a stupid thing and hit install in magisk when i had temp root, i think it installed something to my bootloader, tbh i didnt read it and i rebooted my phone. dumbest thing i did since it bricked my phone. I have since downloaded LGUP and found the proper DLL for restoring the firmware KDZ for 820UMd. if anyone wants more info or links to the files, I can help out since it basically saved me

I do still need help with getting past the backupall-part.sh part of the rooting guide, or should i just skip by it since i can fix a brick anyway?

edit:

I shouldnt have done that. I didn't read the guide all the way through. Now I am stuck on Slot B, trying to boot, but have no software installed on slot b and cant even enter recovery mode. I get there, but it doesn't fully load and won't connect to PC. all my phone shows is the boot logo. time to leave it on until it dies forever.

I have officially bricked my phone.

[LG G8 Guides, News, & Discussion] Krystalmyth:
Hello everyone. My apologies for this if it's been asked but it's extremely unclear and I can not find information on what this is but I've no idea what these 'slots' are for The G8. I'm sorry but the last unlock I worked on was with the Axon 7, HTC 10, V20 and the G3. This concept is absolutely alien to me.

It says requirements are Android 10 or lower. But by lower does that include Pie?

Do I need to have 10 on one slot and Pie in the other like it said? Ive never updated this phone and its still on Pie as it was out of the box. Do i need to update to have 10 as well? What of this other slot? Its highly confusing tbh.

trying to use this guide on an at&t phone (as per https://xdaforums.com/lg-g8/how-to/att-g8-bootloader-unlocking-guide-t4135567) but trying to use lglaf it just stops and doesnt do anything after typing !sabs 0 or 1, if i unplug the phone i get some random errors but it almost always references line 709 and 696. similar thing when trying temproot, when i run it in default mode it will tell me i dont have the right firmware (expected) but when tell it to use a specific number it will sit at selinux_enforcing before exploit: 1 and then not do anything. does this have anything to do with being on 20m or what?
[LG G8 Guides, News, & Discussion] Krystalmyth:
Read this thread back and forth, been reading up threads related to other carriers just trying to brush up on knowledge.

No closer to even being sure I should follow the guide. Is there anyone I can pm some help on this?

I am not inexperienced with rooting devices, but this is understandably very foreign to anything I've done. I don't need to be handheld, but I just want to make sure I understand the device variants, what you all mean by 20D etc.

You guys are skipping terminology I assume is common that is essential for me to understand what you are referring to. So much so that I have to reverse engineer what you mean.

For example op says to find out my device firmware to go into Dev options - about phone - software info and third line.

That block states

mpss.he.1.0.c4-00043-SM8150_GEN_PACK-1.194551.3.194204.3

I am assuming this isn't the information I'm looking for.

The software version is the sixth line and states:

G820U10i

Currently on Android 9.

I'm guessing this means I'm on 20U10i? Not sure how helpful this is, as you can see.

So already following the original post I've run into inconsistency... I'm worried about misreading or making assumptions.

I'm currently not on a carrier sim but my phone is nagging me to update. I'm guessing this is from LG. Since I'm not on Android 10 do I take this update? I'd not, am I eligible for this process? If not then what do I do?

I've nothing but time and am willing to read up on anything you need me to, but really could use the assistance here.

[LG G8 Guides, News, & Discussion] BrandonB1218:
Sorry but where is the inconsistency? You're misquoting my guide, I do not say to go to dev options to get your software version. Read it again. Could you give an example of poorly or undefined terms? Really the terms don't need to be defined outside of the context of the guide. It's a simple do this then that step by step guide. The term definition of something such as 20D should be apparent as it's clearly in the context of firmware versions.

[LG G8 Guides, News, & Discussion] Android#:
A word of caution anyone trying to unlock bootloader or cross flash a Sprint variant of LG G8, be very careful in following the above instructions or instructions from threads that are linked in this thread. One small mistake or failed flash and be willing/prepared to permanently brick your phone.

After i tried to switch slots phone just powered off after the !CTROL POFF command and it never booted up again. While i can't be sure if it was switching slots or flashing partitions using Qfill that caused my phone to brick, it did brick. I did get the phone to go into EDL mode a few times but flashing to partitions with Qfill failed each time (it would flash fine without any Sahara or other errors but it wouldn't go into download or fastboot modes or boot up and I would try again). I even tried to flash the partitions with backups i made before I started this but even that failed. I tried switching cables and ports. I have another phone an LG V35 which i have used with Qfill a lot and it goes into 9008 mode and flashes fine with the same setup.

After a few times into EDL mode using the power and vol + and vol - buttons, it even stopped going into EDL mode. I think the phone stopped charging the battery. I even tried wireless charger to no avail. As a last resort, I opened the back and tried to short the test points to force phone into EDL mode. That failed too. A dead battery would explain this but I can't be sure that's what the problem was. Anyhow this post is just meant to be a word of caution to others. If your phone is working without unlocking bootloader or crossflashing be very careful in attempting this. I wish i had left my phone alone, it worked great, I just wanted to get VOLTE and Wi-Fi calling enabled on T-Mobile. Even the guys in the Telegram group for LG G8/ LG V50 group could not help me except for using teamviewer and trying same troubleshooting steps that I already tried.

I've been in this situation, with the phone not even going into edl mode after a few failed flashing attempts, but shorting the edl points worked even though the battery was almost discharged. I can only suggest trying again, it might work.

I fiddled with my phone for exactly the same reasons as you, to get VoLTE and VoWiFi, reached a low point of not even booting into edl mode, but recovered by shorting the edl points, falshed a few files and got the phone to go into download mode, then flashed the kdz through LGUP and am happy to have the phone back as it was originally, seems it is impossible to make any changes to this phone, but maybe in future ...
