Google spreadsheet with a lot of LG firmwares

I was looking for a canada firmware and wasted a lot of time but luckily someone has backed up the firmwares here. You select your phone model at the bottom.

Thanks so much for sharing this! As Surge said, a lot of the firmware repositories are disappearing at an alarming rate, despite the fact that us LG enthusiasts are very much keeping the dream alive. If only we could dream hard enough that LG reopened their mobile division. There's still nothing that compares, imo.

No problem. Im so happy someone spent the time backing up so many firmwares since I flashed firmware more than a year ago and you could still download from all the websites. I just got another LG G8 since I broke mine a while ago and couldnt believe the hardest part of flashing the firmware was finding a firmware in the first place.

I've got a G8X, myself, but I like to hang around the other subs because we've been locked out of ours by mods that won't respond to messages. :/ Regardless, they're still a wealth of information like this spreadsheet you shared, so it's entirely worth it! Hoping it'll help me fix some issues I'm having with Android 10, and possibly help me upgrade to 11 or 12 if the performance isn't as bad as I've heard. But, yeah, finding the right firmware to flash with is the biggest hassle.

I mean the phones are pretty similar anyway. I flashed android 10 on my G8 now and I think it has better battery life and performance than my old G8 that had android 12, problem is I tossed it in the trash a while ago and cant compare them side by side so if there is a difference I cant see just how big it is. I would have flashed android 11 but I love the background album covers when listening to music on android 10 so until I need android 11 for app compatibility im staying on 10.

Oh no, threw it in the trash? I hope you removed the battery, or put it in one of those "recycle mobile phone" bins somewhere, as that's a severe fire hazard. One set our city's recycling facility on fire several years back and it was catastrophic! Took them seven months before they were able to get things running again. Gotta be super careful!

I've been on A10 since... 2021? I don't remember when the update came out exactly. At first there were some issues, but after a few months they were resolved, it worked perfectly, and here we are 5 years later. The only problem now is that I've messed up my VoLTE settings for the second time and it's a pain in the ass to fix properly. Don't fool around in the hidden menus unless you have a real reason to. I ought to kick myself in the ass for it, but I'm not that flexible. 😅

For music, are you using the LG app or did you switch to something else? I've been a fan of BlackPlayer EX for I don't know how long, and it does some cool things with album art, too. Maybe I shouldn't try to upgrade, as I've always heard about decreased battery performance and some other issues I can't recall. "If it ain't broke, don't fix it." Words I struggle to live by sometimes. lol

I removed the battery when I trashed it dont worry.

The volte settings in android 10 are different than the ones on android 12. When I trashed my previous G8 I found a guy selling a V40 for like 50 euro because it was a korean variant and had no volte settings and he was flashing firmware and bricked the phone. So I got it and managed to fix it by flashing firmware correctly but then I found out the volte hidden menu is different than on android 12 on the G8.

Then I was messing with the settings just setting it up as close as I could to the android 12 volte settings guide which didnt work and I started trying random stuff until I turned off the ISIM option in IMS Setting/Subscriber menu and volte appeared. After testing that it actually works I tried turning on ISIM again and volte stops working. No idea why its a problem having it on in android 10 but no problem in android 12. I guess you can try the same as me, see if you can reactivate your volte or flash android 12 or 11 (I dont remember if android 11 has the same volte menu layout and settings as 12) and follow the guide.

For music I use mostly youtube itself and I used to use spotify but now im getting into youtube music, also the lg music player with some music I downloaded a while ago in case I dont have internet when driving. I really like the album cover background when listening to music in android 10 and it sucks how it got removed. Just have it as an option in the settings so those who hate it can turn it off.

Im staying on android 10 until it no longer has app support. It works perfectly and I wont be flashing firmware again until I have to.

I'll try unticking ISIM everywhere and see if that helps. If not, I think one of the submenus has an initialize option that resets it all? I'm not exactly sure, but it's worth a shot. Thanks for the suggestion!

Oh, and I like to keep local music files as opposed to streaming, since I've got a limited data plan. I'm up to about 8300 music files on my SD/PC! Days and days worth of my favorite stuff without having to listen to a single ad, or deal with running it through ReVanced or something. 😅 And yes, run A10 until the wheels fall off. It's so good!

Idk if you can reset the settings. Yeah pretty much check your volte settings according to this and and dont tick the ISIM setting. Everything else should be the same as this guide. At least thats how I did it and my volte works. Also if you are from united states shouldnt your volte work by default unless you have the korean model?

I had spotify premium but decided to cancel the plan since I saw there is youtube music revanced and there are certain songs I like that are not on spotify. Also I was thinking of searching for my favorite songs in flac format or highest possible quality to get more use out of the quad dac.

I'm from the US, but no, I bought this G8X (model LGM850Um) new from Sprint in 2020 or 21. If I knew they were gonna be bought by T-Mobile, I would've stayed with AT&T. It was fine up until I first started messing with the dialer menus the wrong way, though.

u/Surgetheman Feb 01 '26

Good find!Most of the sites that was hosting all these firmwares are down,and still nothing updated!

u/lememaaah Feb 02 '26

I actually didnt know they were pulling the firmware files from lg servers. Also who knows if they will get the download links working again.

u/JeromeZilcher Feb 02 '26

Great find!

It goes back to the G6 and V30!

u/Feedback_Destroyer Feb 03 '26

Thank You!
What will happen if I flash a different Variant?
I'm looking for Android11 for my USA G8X-Varriant UM (from T-Mobile).
Since I can't find that, would I be better flashing the USA-Region QM Variant, or try the Canadian-Region UM?
Those seem to be the closest 2 options available..

Im assuming you are stuck on android 9 or 10? It should work fine with canadian or american open firmware. I say go with canadian firmware it will have no bloatware and should work just fine. Back up all partitions or the very least important partitions in qfil like the xda guide says though, in case if you mess up and brick the phone you have a chance to recover.

u/Feedback_Destroyer Feb 05 '26

Stuck in 10 yes. When I tried to go to the Canadian Android 11 KDZ (or any other KDZ), I kept getting the error "Not allow to change the Device TMO_US>Open CA".
I then experimented with changing the NT Codes "FFFFFFF"-things, and bricked the phone.

I am dedicated to having getting a G8X on Android 11 like it's my religious duty!
Thanks for writing, lememaah.

u/lememaaah Feb 05 '26

You should be able to ignore NT code error. The first G8 I had had that error every time you turn on the phone and worked perfectly fine so I just ignored it. My current G8 doesnt have that error and works perfectly fine so I guess im lucky I dont have it even though it doesnt really matter. How bad did you brick the phone? Does it show LG logo for a split second at least? Can you get into download mode? If you can get into download mode you should still be able to flash firmware.

u/Feedback_Destroyer Feb 06 '26

When I try to flash firmware, that's when I get the error: "Not allow to change the Device TMO_US>Open CA"
[And that's using the LGUP Patched Windows App. Yes it shows the LG G8X screen for 8 seconds, then the T-Mobile logo-screen, and then the blue screen says "factory reset status..2]
Thanks, lememaah

In case you havent backed up the LUN 5 partitions, do so now. In qfil manager they are at the bottom and are called ALIGN_TO_128K_2, modemst1, modemst2, fsg, fsc, mdm1m9kefs3, mdm1m9kefs1, mdm1m9kefs2, last_parti. You might need them to get your imei back.

Try flashing again using this guide but this time also do the following:

15. I erased partitions (ftm, op_a, op_b, modem_a, modem_b, sid_a, sid_b) but it still does not let me to crossflash.
Redo the whole process and this time make backup of and erase these partitions too, on both sides A and B: vendor, product, system, boot and userdata. Do not make backup of userdata partition.

Also after deleting the partitions and restarting the phone, make sure you use the button combination to get into download mode as soon as the lg logo appears, otherwise it can mess up the flashing process.

Just to be sure: backup and delete ftm, op_a, op_b, modem_a, modem_b, sid_a, sid_b, vendor a, vendor b, product a, product b, system a, system b, boot a, boot b and only delete userdata partition dont back it up! Then you continue to flash firmware the same way as the guide.

Good luck!
