No I followed here another guidelines, plus yours. A now everything work excellent with 5G network with Volte. I try today take my phone to Germany and see if going good roaming etc... I used V2. for A12 but I have A11. Just one think fingerprint I fixed, bud I think it's reaktive slowly ? It's because slow hardware?
In Germany don't connect to Volte, and why it's impossible make any calls without enable Volte ?

Well tty this, get modem_a backup from verizon firmware and restore to EU rom device, or you can extract from verizon kdz modem_a and flash and see what will happens.
Did you try in europe with werizon firmware ?
Yes this been, first think whats i do. But in original version Verison, its not posible activate simcard (beacose i have T-Mobile.) Verizon write its not simcard from Verizon, then its imposible make any another call. ... Oh my god. I try restore original VM modem_a to EU-A12 and now works call in EDGE. but quality in EDGE its terrible.. i hear but he hear me really bad..

3G my Operator in Czech Republic definitly cancel(many towers change 3G for 4G network.) this i dont know, but 2G for calling work, same for 4G/LTE + Volte work, and data same. But its any issue not brake modem_a from VM and add Suppport 5G brand ?
What happens if you just use the stock modem image from the EA-A12 firmware?
That makes the most sense, should actually work best.

It's strange that behavior... I have several North American V60s (AM, VM, TMO).
I crossflashed some on EA firmware, without problems.
The only thing I had to do to get VoLTE and WiFiCall was BL-Unlock, Root and /System RW.
You probably already know the following thread link as a starting aid (especially posting 3)...

Similar Issue
I have a similar problem so I thought to post here.
I have a I5500L.
It came with this firmware out of the box I5500LUYJP9 (2.2) it was locked to Movistar (Venezuela).
I unlocked it with SRS to use it with my carrier (Digitel Venezuela).
No matter what I try, I cannot make it work with 3G, only EDGE.
I've tried many things, changing bands, forcing WCDMA, and a lot of tricks found on this and other forums, but nothing works.
It's not that it doesn't work with 3G and goes to EDGE, but that te phone is only working on basic GSM, and cannot connect to the network if I change any setting.
Funny thing is my wife has an I5500 (without the L), it was bought unlocked, it came with some European Firmware, and hers works perfectly with 3G.
She has the same carrier as me.
Another thing to note is, my phone detects a network called "Digitel", her phone detects a network called "DIGITEL-GSM".
¿What could be the problem?
¿Could I flash some European firmware to my phone to make this work?
¿Will this affect the SIM unlock?
Thanks.

What are the implications or possible sideffects of changing the baseband?
I mean if a baseband won't work, there should be another one that does right?

there no danger in changing basebands, the only thing is, some will, and some wont work. you should just try the baseband from wherever you are 1st, but if that doesnt work, try another. doesnt matter if you are from UK and you use an american baseband, if it works, its completely fine
has it worked?

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.

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

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.

I tried to flash Sony Xperia 1 SOV40 into J8110 Global Rom, but does not have voLTE available for Malaysia
Someone told that can mix SEA version sin with Global Version sin, i have tried to move the modem.sin (All three from J9110 SEA version) into the J8110 but still not working
seeking for any advice to make voLTE work
Thanks and appreciated
You can try Customized JP OEMs.
Don't need to do the modems Just flash the OEMs only.
It will definitely work.
I have J91110 and it worked for me.
If you already have the files than thats fine.
If NOT you start it with the XperiFIrm and start download. When it says downloading 3 of 3 then stop downloading.
Open Flashtool and Use Files Decrypt to extract the OEMs.
Just flash anything with the name OEM using newflasher.

Malaysian here, which global ROM your guy using? I try all j8110 ROM + OEM still can't get the volte
Interesting, I've tried flashing OEM files from customized JP/SEA/UK into my J8110 variant, but still can't get VOLTE working, I tried flashing JP oem files, all it gave me is a corrupted bootloader, (I figured it may have been caused by flashing 3 different firmwares onto my device) , My last option is to factory reset it.
Thanks for this, I have an Xperia 1 AU KDDI Japan SOV40 flashed with J8110 UK Firmware, and flashed Customized Japan OEM for volte, now volte working, by the way I'm from the Philippines and I use DITO Telecommunity SIM which they don't have 2G and 3G Networks, only 4G and 5G that's why to use calls you need VOLTE Enabled on your device.

Where did you get OEM from? Still try a solution how to make it work but still haven't found any better steps to do since I'm afraid of bootloop or something else.
Now I see that 5G are officially announced before, a lot of telcos had to discontinued 2G and 3G networks. 2G network in Malaysia will stop working soon. Not sure when it is.

I just installed Customized JP OEM by following on the first page's instruction before I formatted my phone. But nothing changed. After that, I tried formatting my phone without flashing oem but the result shows nothing about VoLTE. So, I just keep using it without VoLTE function because I don't wanna take a risk to install it again due to afraid of having a bootloop if I feel hesitated to make it work.
But, I will try to find another way to fix that problem soon if I got one.
I recently buy Xperia 1 SOV40 single sim. Seller say that Umobile and YES doesn't work in this model. I try insert Umobile sim and can be use to call and internet. I not sure about VoLTE. Do I need to flash any firmware to make sure Umobile get VoLTE? Or SOV40 not support Umobile VoLTE frequency?
Please help me with Volte,
Really need it

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?
Hello
I got this tablet SM-T225 and used it with T Mobile in the US, but the data stops working a lot. some times it shows 4G on the notification but no internet, other times it shows "E" in place of "4G" and very very slow internet or no internet. I tried moving to different location but the same problem, some times work and other times doesn't while the phone and my other tablets work normally. the WIFI works without a problem.
the tablet had CSC CHO and the service provider software version showing OWO CHO
the tablet is rooted and bootloader unlocked.
my questions
is it a tablet problem or this model doesn't work reliably in the us?
or it needs to be flashed with different firmware?
thanks

Seem bootloader ok , firmware ok, try to clean flash with stock.
But now where are you? Chile or US. If live in us why not installed US firmware Region.?
I am in the US and this model is not used in the states by any provider, no firmware for it in US as far as I know https://samfw.com/firmware/SM-T225
I flashed it before with stock firmware (CHO) after I flashed it with magisk patched boot loader but same problem, I will give it another try now. at first when I flashed it with magisk I used in the in the CSC slot HOME_CSC_OWO_ but later I used CSC_OWO_ if that matters.
unfortunately after flashing stock firmware https://samfw.com/firmware/SM-T225/CHO/T225XXU1BVGB same problem.
I have this tablet in the USA on att post paid with a "phone" based sim. It can txt via the native mssgs app or Google messages. It won't make phone calls via the native app. Voip calls over Google voice will work.
Also tmobile sells this tablet as a the sm-t227 and it works fully ont their network

Can't used sm-t225 with your provider. Sorry
I am aware that the 227 is used by T Mobile, but I read a comment on XDA that the Bootloader of 227 used in the US is not unlockable and I went with the 225 to be able to unlock the bootloader
I am returning.
I appear to have basically the same issue. I cqn send texts but mobile data just does not register. I have model T227u that was sold through Fido in canada. I hqve a 12 gb data plan and everything works fine on a phone. (I also have a note 9 that is starting to crap out.)
It is running android 13 and is rooted with magisk 26.1 patched boot img
solution for this issue is to just Flash one of the SM-T225 official firmwares for T-Mobile Europe. (I switched it to using the Poland (T-Mobile) - TPL version. T225XXS2CWA6

Now, that IS interesting, particularly if that conclusion applies to every "unlocked" version of T225 sold in the Western Hemisphere. Mine was sold by Amazon's on line from store, specifically advertised to work as phone etc. Been trying to solve by GSI, twrp root for a while. Getting an "involuntary" refund from Amazon so it's worth trying.
