[Q] Problems with LG G3 D855 Operating System - Android Q&A, Help & Troubleshooting

Hi everyone,
I'm having issues with my LG G3 D855! It was originally locked to Optus in Australia, but I have recently wanted to root it. To do this I found I had to downgrade to Android 4.4, which I did successfully using the LG Flash Tool. It worked well, but it messed up at the same time. I actually flashed the European version of 4.4 over instead of an Optus version. As someone with little experience in the field, the European/International version seemed the right one since there was no Australian versions on the site. LG wouldn't replace the firmware unless I coughed up $350, seeing as I voided the warranty. After doing further digging online I found a Telstra version of the LG G3 firmware but the phone repair shop said that flashing a Telstra version over would lock it to telstra and that I would require a Telstra sim to use the phone! At the moment my phone is functioning okay, I'm able to text, call and mobile data and wifi both work. The issue is the missing Australian apps and the many European ones that aren't mine. Also out of curiosity, has the European G3 received 5.0 yet? It didn't show up in the software updater for me. Looking for any advice I can get with this... If you have any further questions about the functionality I will reply as soon as I can.
Thanks!

LG v10 korean version-flash or not

Hi to all!
This is my first post here.
Couple days ago i purchased LG v10 (F600L) with 64GB of ROM! This is korean model from network U+.
I live in Croatia so I can't use some features from phone, and it's not the major problem.
I wonder if is possible to flash phone with H960 firmware? Via LGUP app from my PC? Is it problem because my phone has no unlocked bootloader and in some posts on the internet I readed I can brick up my phone.
4G does not work either. Probably only korean version of LTE, not supported in Croatia.
So, if I do firmware upgrade via LGUP, with euro-version, will I get phone with only 32GB, will LTE bands be opened to euro-networks?
I didn't say that I can't upgrade my korean version to Android 6.0, via OTA or LG Bridge. It says Cannot check the latest firmware.
So, guys, to do it or stay out of any attempting?
Thanks and regards from Dubrovnik!
Is it true that noone knows?
Cannot, ne mozes! Just try to read a little more about it.
If you click the link you can see there is support for 4G in Croatia.

I can see Croatian operators can offer me LTE 1800mHz only.
So, in suburbs of croatian big cities I have LTE, but only in streets, outside places etc. Whei I enter in some bar or restaurant, LTE wanishes.
I'm on VIPnet Croatia which provides LTE 800/1800. It seems my Korean V10 works only on 1800.
Too bad. Cause, it's good phone. I upgraded recently to Android 6.0 (MM) via link on this forum and it works even better than on 5.1.
On posts on this forum(s) I can see that my device cannot be flashed with another firmware. I've downloaded Turkish version (64GB) but LG UP says Error. It seems I have to root my device, but even than, it's not for sure that all LTE bands will working.
Koreans made the mess by locking with brandings their devices.
@moby77: for what I know, you can't flash a different firmware... a brick is nearly assured.
But you can try this code: 5457#*600# then go to Multi Band Selection and check LTE bands that are available in your Country.
Don't know if that procedure works in your device, but it well worth a try!

I am not sure but most probably flashing wrong firmware will brick the phone. However, one thing I am sure is just flashing the firmware on different version never unlocks the bands of 3G/LTE. These bands cannot be unlocked this way. If F600L does not support a particular band in your country, it will not run LTE no matter what firmware you flash.
F600L is very well locked by Koreans so I san't do anything except flashing new kind of firmware, but one provided from U+ network.
One day I got mad, so I used LG UP, downloaded firmware for Turkish H960, and pressed Start button (it really was pissed off so even I bricked phone, my fault. Totaly insane, but...). After 4% od doing "something" it said Error, cannot flash firmware! (or something like this).

you have H901-10c official os bcz when i upgred using LGUP my phone is not starting as well as not showing charging sign when i am connect my charger

A guy i know at work has this model successfully rooted.(i saw with my own eyes).But the problem is he got layed off and i cant contact him.He also said that the tmobile version is identical to canadian version as far as specs and hardware.And it makes sence to me because i own a samsung note 4 canadian version and can flash any T-Mobile rom.Im wondering if he rooted using T-Mobile stuff.Any thoughts on this will be welcome
By the way i am on N 20c version using telus sim and factory unlocked.pretty sure he had exact same

It is the unlocked model sold directly by LG in the USA, so it is non-carrier firmware.

You can try this website.

since your phone is network unlocked I think it might be safe to reinstall the firmware.

Thank you. I found out that they never released the KDZ for the factory unlocked phones (region USA). So, the only way to update my phone would be to flash carrier firmware, which, is kinda risky, since it would technically be a crossflash. I would likely lose certain features, such as Wi-Fi calling and/or VoLTE. One of the few firmwares that supports wi-fi calling is the T-Mobile firmware, but I wouldn't flash that firmware because it is different than the hardware of my phone (their model has 2 GB of RAM, mine has 3 GB of RAM, etc...

Hi there,
Yes, while I was researching it online I found two firmware for this phone for the US region. But anyways have you tried using a PC suite from LG to reinstall the firmware. Or have you tried going on to the recovery mode and just reset the whole device. Or better try to install a custom ROM, to be honest I think it might be okay if you flashed a Europe region firmware, but make sure you back up the current firmware. I flashed a Samsung phone which was used to be locked and then I unlocked it after that I flashed the carrier firmware and it didnt carrier locked my phone. But anyways try your best.

LG V30 H931 AT&T model cannot update O.S.

My phone LG V30 H931 black AT&T model
i bought in dubai as 2nd hand phone and now
im trying to update OTA it says " Your device is already updated " . i have checked in AT&T software official site and the device has available update for July 2019 security patch. My phone security patch is still last July 2018 since i purchased it.
I also tried LG bridge computer update but it shows " LG bridge cannot detect your device O.S. " does it mean im stuck in 8.0 Oreo ? weird, i have a korean version LG V40 and connecting to Lg bridge has no problem it detects the current OS of my V40 LGU + model.
So i realized it maybe because my phone is AT&T model , USA based phone and im not using at&t sim nor network since im in Dubai now
Now question ,is there any other solution to update into android Pie 9.0? or should i just. sell my phone and better buy another V30 or V35 korean version which has no problem in updating O.S. rather than USA based phones which are restricted . thanks

Months ago, I wrote a Guide for AT&T H931 and Sprint LS998 which can't update, if you are not AT&T or Sprint customer. It tell HOW to update them.

No, doesn't have Pie yet, but soon will. They will get Pie. But this question is not really about Pie, this is about updating H931 at all. There's only one way to do that, if you are not an AT&T customer. I tell how in the Sticky.
I've answered this question two or three dozen times and people just keep creating new threads to ask again. Thought sure the Sticky would help and maybe it has.

Device being carrier unlocked (by some code) has nothing to do with getting carrier-approved updates only allowed for that carrier's customers.
AT&T and Sprint don't want you using their devices on other networks, and if you do, they punish you. They also don't care about AT&T/Sprint customers who may sell their phones on eBay to non-customers.
There is a solution. Read the sticky.

Only AT&T H931 and Sprint LS998 are ostensibly restricted. There's a way around the restriction, explained in the sticky.
Neither carrier release public KDZ for their updates. They will only do FOTA (Firmware Over The Air) for customers who have their SIM cards.
This is why LG Bridge won't work for H931 or LS998, because you can capture the URL to the LG Server and post it publicly. We do this all the time in the OTHER variant KDZ threads, where you can download KDZ straight from LG Servers. AT&T and Sprint won't allow that.

Thanks for all the responses sir, i decided to sell my at&t used phone, manual upgrading software is too much hectic and risky for me as an ordinary user.
So this is a lesson learned from me and i strongly advised to all foreigners like me who wants to buy 2nd hand LG phones ,better buy korean variants or international version, avoid US based carrier brand phones.
Sk telekom, LG U + this korean variants are way better ,no restriction any country u go u can update the O.S.
Using my LG V40 korean variant thanks

* I've already explained it's not all U.S. carrier phones. However, if you research you will know AT&T and Sprint LG phones do not give updates to non-customers, nor do they publicly release KDZ update files. Those two carriers only release FOTA (firmware over the air) to customers.
* Most everyone here in this forum uses or has used LGUP. It's not risky if you just read the directions.
Many people on different LG variants don't get OTA updates (like India H930DS) and even my wife's native US998 -- and it's not because they aren't U.S. carrier customers. So they come here to get updates, and manually install them via Dev Patched LGUP.

Calls not working through Simple Mobile / T-Mobile network

I'm at my wit's end on this. Calls stopped working the other day due to 3G disablement as far as I can tell. AT&T model unlocked and using with Simple Mobile on T-Mobile network. Calls would just say "Calling" for a long time and then eventually disconnect. I could switch to GSM and make calls again, but slow data. Simple told me to get a new SIM and when trying to activate, it shows ineligible IMEI due to no Volte it seems.
I'm trying to get that fixed, but running into various issues.
LM-G850UM
I tried to crossflash (https://forum.xda-developers.com/t/tutorial-crossflash-bypass-opid-mismatched-error.4345963/)
I flashed G850QM30c_00_NAO_US_OP_0224.kdz but it didn't ask me to change the model, so it still shows LM-G850UM software G850UM30c. IMEI is the same.
Since this didn't get calls back or Volte, I tried updating the MBN (https://forum.xda-developers.com/t/...ther-qualcomm-powered-lg-devices-too.4343655/)
Data shows 4G. Calls don't even try to connect.
I don't know what to do next and don't have much time to try to figure it out. I like the G8X, so I'm hoping there's a way to save it.
Any thoughts from the experts?

Make a back up,and cross flash it with T-Mobile firmware.Problem solved.
Thanks Surge!
I crossflashed to general firmware. Where's the best place for the TMobile firmware? Just off their website? Will that lock the phone again, or will I still be able to use the Simple Mobile Service?

That's where I got my KDZ before. I used the one here: https://lg-firmwares.com/lg-lmg850qm-firmwares/ and used the 3/24/22 version for Android 11. When I flashed it with LG UP, it didn't ask me to change models, which I'm not sure if that's why it didn't trigger it to start working again.

Most are using the international firmware for the G8 and G8x models.Which is what the qm firmware is.If you're carrier is T-Mobile or any T-Mobile MVNO,I would solely use T-Mobile firmware.My G8x is AT&T branded and factory unlocked,and I tried using Tmobile service about 2 months ago and was having issues sending text messages.I could place and receive calls and get text but couldn't send them period.
Yeah, so my G8X is AT&T unlocked. AT&T didn't activate VOLTE on this model, so when T-Mobile shut down their 3G network, Simple Mobile calls won't work and the current IMEI shows it's not eligible (because of the model.) At least that's my understanding so far.
So for the G8, is this the firmware I should crossflash? https://lg-firmwares.com/lg-lmg820tm-firmwares/ or I could try the QM which may or may not work. Is that correct? Basically going to the 820 firmwares instead of the 850?

I would go with the T-Mobile firmware since you're on their network.It wouldn't make a difference with VoLTE enabled with an AT&T sim.Once you pull the sim,and swap it it defaults back and turns the IMS settings off until it receives the configuration from their servers.Yes,820 firmware.It at least has the higher android builds,and better security patches.Once you put T-Mobile firmware on the device it should all work regardless of IMEI.
Edit:Make a back-up.Don't forget to do that first!
OK Surge....you've been helpful and seem to know what you're doing. What did I mess up?
I followed the cross flash instructions. I flashed the 820QM firmware first, and System loaded but the touchscreen wouldn't respond. I could only use the hard phone buttons. Decided to go to what you recommended with 820TM and it wouldn't boot at all - black screen - but I could still get to QFIL and LGUP.
I reflashed 850QM and touchscreen works again and I'm back to where I started.
When I flashed 820s, It did ask me if I wanted to change model numbers this time and I said Yes. And it asked it said it was changing some partitions on the 820 loads.
I may have been working on this too late. I appreciate your help so far.

I think someone else encountered this once before,and it was caused by certain manufacturering dates of the device.Some models can use 820 firmware,and some can only use 850.Looks as if yours is kind of stuck with 850 firmware only.I think the AT&T version I have I could go either way it worked with no problems.I still have my G8x but never really used it.I bought it because it came with the dual screen attachement,and $125 I took it.Here's my Sprint copy if you want to give it a try.It's a LUNS copy minus LUNS 5 for IMEI information etc.I was in the same boat as you on certain features not working with AT&T at one point myself and had to crossflash the Sprint version of the device.With that being said,try this one from LG Fans first.If that doesn't work,try my LUNS Sprint copy and let me know which ones works the best.

So interesting news....I obviously didn't try making calls last night at 2AM, but apparently reflashing with the same exact 850QM software I used before seems to have fixed the issue. Maybe changing the model to 820 and then changing back to 850? Who knows? That's like the 3rd thing that happened with this process that I have no idea why it started working differently, but hey I'm happy and back up and rolling.
Thanks for all of your help, Surge! I was truly at wits end, and had already ordered a new phone, even though I'm happy with the G8X overall. Now I can return that and keep rolling with the G8X.
Thanks again, you were a huge help and its much appreciated!

Glad you got it working!I run in to a same similar issue with a Note 8 I have,and it being an international unlocked AT&T phone.No calls would work period,and swapped firmware over and over and finally started to give up and flashed the stock firmware back and it worked.It's something that hangs in Android with the changed IMS settings that are sent to the device.It's all odd at the moment with carriers,but nothing surprises me anymore..lol..
"G850QM30c_00_NAO_US_OP_0224.kdz" Is a BPT kdz and is not truly open even though it says, "NAO US OP".
I got the phone working by using "G850QM30b_00_NAO_US_OP_0902.kdz", the "real" open kdz. Everything worked fine after that.

Yes,the firehose will always work regardless of the Android version.Also from what I have read,yes the same procedures work for A12 for root and unlocking the bootloader.As always,backup your firmware before rooting and attempting to unlock the bootloader just in case something goes wrong!

Do you think there is any point to crossflash
USA G850QM40b_00_NAO_US_OP_0805.kdz
on ATT G8X to be used on Tmobile network? I can do the VOLTE patch after rooting it . is it worth the headache?

QM versions are international unlocked versions of the firmware.My branded AT&T G8x had issues sending text messages with T-Mobile service I do remember.I crossflahed my variant with the QM version and it worked flawless after that.But,I do have a full backup copy of the AT&T firmware if I ever decide to put it back.

May I ask how did you back it up?
also if I have androind 11 ATT can I crossflash to android 12? that should not be an issue right?
the partitioning is not changed in the update?
