Hi, could I flash the t-mobile firmware file or rom to the verizon lg g5? I switched to t-mobile, and am able to use the verizon phone, but lte drops to 3g for calls and lots of the time data shows up as hspa when I check the icon. If it can be done, please explain how. Thanks in advance.
No you can't flash the T Mobile firmware.
other firmwares beeing flashed on different lg g5's
So, there is no way to flash different firmwares on the verizon model, just other ones. Is this because the bootloader is locked? How can people flash a different region firmware on some of the models?
I to am curious on this, i have called LG and was told that the only difference between the T-Mobile and the Verizon LG G5, was software based, and that their was no hardware differences at all.
If that is true, why would we not be able to flash the T-Mobile rom onto our verizon phone?
DO NOT ATTEMPT THIS OR YOU WILL BRICK YOUR PHONE BEYOND ANY REPAIR. It has been said MANY times before, google it first

The hardware is essentially different... Has nothing to do with locked bootloader, u could still use LGUP to flash regardless but it would likely brick your phone. Drops to 3g because of the bands used, there may be a workaround but it's unlikely.
Title says it all really. I hadn't seen any indication that Oreo would bring any changes in the WiFi calling or VoLTE front, but the facilities that had been only available on Three branded ROMs, are available in Oreo.
Cheers for the info - on Three but using an unlocked phone so this will be useful when I've finally got the update.

Same here - just flash the XEF version if you have can download it, and have access to Odin.
Great news, also on three on the unbranded note 8. I was looking for volte / wifi yesterday actually and realised I was stuck with the terrible app ! Is it available yet or are we still waiting?

The release is currently only available for the XEF CSC, but as that is part of the OXM multi-CSC that covers the UK's BTU, then it's effectively identical to a UK update anyway. You can download it and flash it to your phone using Odin.

Yeah sorry, I got to reading after I posted that and saw your post in the other thread. I'll give it a go shortly - thanks for replying mate. Much appreciated!
They’ve also updated the modem Firmware to support additional LTE bands including B32 which three are currently deploying in my area.
Occasionally callers can't hear my audio at the other end of the call whilst using WiFi calling, I'm BTU/BTU/BTU on Oreo on 3UK. Would be interesting to see if anyone else is having issues. I'll check the detailed IMS settings when I have some free time.
From the Three site:
Devices that didn't come from Three.
Right now, all 4G Super-Voice compatible*iPhones*will be 4G Super-Voice enabled once the carrier settings have been installed, even if they didn't come from Three.
4G Super-Voice doesn't work on other non-Three devices yet however, even if the manufacturer has stated that it's VoLTE compatible. We're working on this, so be sure to check back for updates.
Has anyone experienced data transmission issues on Oreo and 3 UK?
I updated to Oreo via XEF Odin flash and then Update push but was getting very intermittent and "hangy" LTE & HSDPA data transmission...
I flashed back down to 7.1.1 but if no-one else has experienced this I may try again :fingers-crossed:
S9+ (direct from Samsung) user here using my Three SIM from my old S7 Edge contract.
No WiFi calling etc, what is it that I have to do to enable it? Not flashed firmware before & I'm concerned I may void any warranty etc (on Samsung Upgrade program for the S10)
Thank you in advance for any advice.

I can say that I've not noticed any data or voice issues (WiFi or otherwise) since switching to Oreo.

This is the Note 8 Forum and we are discussing the Oreo update for that specific phone. There's no guarantee that Oreo updates for other phones will include the VoLTE or WiFi Calling settings for Three. You would be better off directing your question to the S9+ forum.

I have the 950N as well. I would suggest downloading a 950F based ROM and then flashing TEKHD's CSC detonator(its in the dev section) which is T-Mobile based. It'll give you access to VoLTE and I believe video calling as well. I am currently running WETA 6.3.3 and have flashed that CSC pack. I am able to enable both the MMTEL and RCS switch. VoLTE is working fine for me now.

I am using a dual sim variant SM-N950F, both Sim cards are from 3UK so can I flash this firmware to get wificalling?
I use my SIM 1 for calls and texts and SIM2 just for data.
Just want to let you know that s7 edge btu with newest oreo update have WiFi calling enabled so no need to have 3 network firmware. Hope this helps someone.
I've just purchased a note 8 (UAE version) and using with 3uk I have Wi-Fi calling without any ROM adjustments

Is it possible for me to flash that OXM multi-CSC on my N950F model without root? I'd like to have wifi calling and volte here in US.
I'm on the N950FXXU4CRH3 build number. (XSG)

You can flash on your N950F, but without knowing what CSC it currently is, the results could be a little unpredictable.
However, I can't imagine it will give you what you want in the US, as none of the native CSCs in OXM target the US carriers.
Sorry to bring back an old thread but I was wondering if you could help please? Does this mean that Oreo firmware, regardless of source will allow Three's VoLTE (4G Super Voice) to work on any Note 8, even those not supplied by Three? My phone is running 8.0.0, is unlocked, and I have just ordered a Three SIM.
TIA
Sorry about creating a thread but wanted to make sure I can flash Sprint LG v30+ to T-Mobile without issue. Tried to read a few threads but from my understanding Oreo had messed things up at one point.
Does it have to be unlocked through Sprint first?
Simple flash T-Mobile or international rom makes it usable?

No, doesn't have to be unlocked through Sprint first. And Oreo didn't mess up anything.
Some of the T-Mobile guys are complaining about T-mobile Oreo. I own five US998 and don't see anything they are complaining about. Must be a T-Mobile H932 issue.
You will convert LS998 V30+ to official carrier unlocked model US998 V30+ with Oreo, and run on T-Mobile. Converting to US998 carrier unlocks the phone and gives it fastboot flash commands.
You can stop there, or you can bootloader unlock, install TWRP and root the phone.
Whatever you do after that (Install ROMs or whatever) is your choice.
You will NOT flash T-Mobile firmware onto the phone or you will brick the phone.
Many T-Mobile users are running rooted US998 (original or converted) on T-Mobile.

My Sprint V30+ is sim unlocked. If I flash it to carrier unlocked phone and toss a TMobile sim in it, will I get access to VoLTE?
Right now when I toss a TMobile sim in it, calls drop to 2G/3G.

If flashed to US998 Oreo you will definitely get T-Mobile Wi-Fi calling.
T-Mobile users can answer specifically about T-Mobile VoLTE on US998.
But since you can temporarily drop down to HSPA for phone calls and still get data, it's not critical. I don't have VoLTE on my AT&T Prepaid plan and I don't care.
Hey, I bought a LG H930DS from a reseller who was probably importing stuff from abroad, so while I'm mostly based in EU, I've the AME region in my phone (all stock).
And so far, no OTA or LG Bridge update for me and still sticking to V20f-AME-XX... There has been some slight delay even on Oreo, but wasn't so long IIRC.
However, at this point, since I don't care about sticking to this region, would be safe to update it to HK (or maybe the recently arrived TW) images, preferably without loosing data, and (for sure) dual-sim?
I've seen the changing region topic has already been covered in the past, and so in theory should be, fine but I wonder if the fact that would also imply a switch to a mayor release anything.
And if all is good, can I just use LGUP?
same here , i also own the h930ds with v20f-ame version . there's no 9.0 pie ota update nor kdz for it till now

That link you posted is from 2 years ago. Some of that information is not correct. At one point we thought flashing H930 over H930DS changed bands but it doesn't. Remains H930DS bands. We also thought flashing H930 over H930DS made the 2nd SIM not work, but it doesn't. Both SIMs still work. That's the danger of looking at very old threads. Back in Feb 2018 we didn't know all we do now.
And we can't go back and change every thread from two years ago...
You can flash any H930DS Pie or even EU H930 Pie KDZ and your phone will have Pie.
The only caveat is if any carriers have VoLTE/WiFi calling on AME firmware, by now having different firmware those options will probably not work. However, even that isn't always true... On latter EU Oreo H930 KDZ, the India Jio VoLTE started working when on earlier EU H930 it did not. At first the India carrier VoLTE was only reserved for India region KDZ.
I don't know about AME carriers.
Thank you, in fact I was quite sure this wasn't anymore the case as I read updates around later the post.
However, I don't need VoLTE calls, nor AME carriers, given I live in Europe.

I also live in the EU and have the H930DS AME version.
If you don't care about Volte (I don't know if it works as my carriers don't use it anyway), then you can safely update to any H930 or H930DS variant via LG-UP.
Personally I am using the EU H930 firmware as I found it was the one with more regular updates. The calls and data work perfectly fine in both my SIM cards.
The only change I noticed is that despite flashing the EU region firmware, in the phone settings it is shown as GLOBAL-COM, and I never received OTA firmware updates, I always had to update via LG-UP. But I don't think we are going to see more updates from now on, so this is not really an inconvenience.

Strange your WiFi isn't working. What happens when you manually turn it on and off?
Also try latest 31a EU H930.

Wifi is on but it couldn't connect to router probably.
After 10 times turning on and off the wifi or manually select connect it will connect to router but about 5 seconds after that it will get disconnected again. Sometimes it would stay connected about 1 hour but that is rarely happened. It could not also connect to other phone's hotspot. Changing the adsl modem couldn't help that
. I tried liquid remix based on pie and found the same issue. I used to use the phone about 2 month like that but couldn't stand that way and rolled back to oreo
I guess pie roms wont work on the ame version yet

Strange. Because not many complain about Wi-Fi on stock firmware. Stock Wi-Fi is what people want back....
Having said that, I'm not a big fan of LG stock Pie. Which is why I never upgraded and an still on stock rooted Oreo.
In Pie, try flashing your Oreo AME modem in Dev Patched LGUP to get your Oreo modem back. See if that does any good for your Wi-Fi?
See here:

Well the pie modem obviously doesn't work for some devices, and the oroe modem is a fix, as mentioned here:
https://forum.xda-developers.com/showpost.php?p=80271901&postcount=1580
To do this, get the "DEV PATCHED LGUP"
https://forum.xda-developers.com/lg-v30/development/h930-lg-v30-european-market-h930-t3779076
1) Go into download mode (power off completely, then hold volume up button while plugging in USB cable)
2) open patched LGUP and flash OREO KDZ to DL PARTITION mode.
Click "start"
In the pop up box select only "modem"
Restart, done.

Yes you can use LG-UP to flash any firmware from H930DS or H930 without wiping data. You will only lose your home screen configuration. Just make sure to select update and not refurbish on LG-UP. The AME version has never updated from V20f, so this would be your only option to get more recent updates.
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?

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?
