Hi,
I have an AT&T S21 5G that I unlocked and now use on Verizon. It works fine but it's stuck on an older version of Android 12. When I check for updates in settings it doesn't show as having any, yet I've read Android 13 was pushed to Verizon already.
Is it because I switched carriers that it wont show any updates? Do I have an option to push Samsung OEM Android 13 to my S21 without losing all my stuff? Am I just stuck with what I have?
I'm just looking for options and some options.
Thank you for your help

Download the latest U/U1 firmware from SamMobile/ Frija and flash with Odin. Make sure you flash HOME_CSC, not CSC as that will wipe data.
Ok, so when I look up the model on SamMobile it only shows up to Android 12, so maybe 13 isn't available for it yet? My software version is AT&T, I wonder if I should push it over to the Verizon latest update even though it's not 13.

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
Can anyone point towards where can i find unbranded Tab s7+ 5g firmware. Currently my device is unlocked verizon model with model no. T978U.
I know U1 versions are generally unbranded ones. I've flashed my s21 ultra which was also on verizon to unbranded version. But i cannot find any such rom for tab s7+ 5G. All i find are the carrier versions available to download.
There is no such beast but I did root and unlock the boot loader for my tmoblie tab s7+
Magisk is working although viper is not working right
Hello, looking for some help to see if anyone can help me find the firmware of my A526U specifically for AT&T? I have moved my phone over from TMobile where I purchased it from, and am looking to re-flash it to AT&T. Was working fine for a few months, now I'm no longer able to make or receive calls.
After inserting the new AT&T SIM card, the TMobile splash screen still shows up. The Service Provider software version reflects TMobile still as well and I'm concerned that for whatever reason the phone did not fully update after inserting the new SIM. I spent 2 hours on the phone with AT&T support after the store said they couldn't help me. Pulled the SIM card out, restarted phone, put it back in, reset network settings etc. I've searched sammobile and I cannot find the AT&T firmware, only TMobile, Sprint, and TMK. I would sincerely be greateful please if anyone could help me by pointing me in the right direction for the firmware for this model phone.
AT&T doesn't make their firmware available publicly - for any device. I have a source who can get me Samsung firmware for any USA device - even AT&T. But he charges me for each one
I appreciate the quick response! Is there any option I have here? Could I try flashing a "U1" firmware to his phone then? He's currently on A526USQS4CVA6. I actually found your other post as I was also working on my note 10 plus - https://forum.xda-developers.com/t/n975u-and-n975u1-firmware-links-here.3957648/. If I'm reading that correctly, I should be able to correct? If so, how can I tell if the version I'm downloading is "downgrading the bootloader"

1. Yes, you can try flashing U1 if you want
2. You can't "downgrade the bootloader" - Odin won't let you.
3. In A526USQS4CVA6, "4" is the position of the bootloader level/revision/binary. Make sure that whatever U1 firmware you download also has a 4 in that spot and you'll be fine. (Or just get the firmware from Frija or one of the other similar firmware download tools, because those throw you whatever the newest version is automatically)

Thank you very much sir! I shall give this a go this weekend! You guys rock!
My AT&T N10+ N975U is running on Pie. It transitioned seamlessly with no changes made on my end. It was already using 4G VoLTE though. Same sim card.
I would contact AT&T advanced tech support as there may be an easier way.
4G VoLTE needs to be enabled in hidden settings.

Your AT&T phone? So it's originally an AT&T model that you're still using with them? That's not the same situation that the OP is in

The U is the AT&T variant vs the U1 which is the unlocked variant, correct?

Yup. But OP has a T-Mobile model that they moved to AT&T. There's also no guarantee that a Note 10+ will work the exact same way as an A52. You're also running 3 year old firmware, while OP is fully updated.
So i don't see the correlation.

The old firmware works fine on 4G VoLTE... that's likely not the issue. What is the issue is it wasn't running on 4G VoLTE so it's likely the settings and sim card need updating not the firmware.
Hi All, thought I would provide an update... After spending hours on the phone with AT&T support this week and being frustrated with the AT&T store, I decided to proceed forward with flashing the U1 version. What started this all was last week my son could no longer make or receive calls on his AT&T A52 phone (we ported it from TMobile September 2021). The store and AT&T advanced tech support said there were issues with people's BYOD devices, even though the A526U and A526U1 shows on the supported devices list. The store rep said he's been getting people in left and right that can't make or receive calls, and all they can do is upsell customers to an AT&T branded phone.
SO... my son's phone was on A526USQS4CVA6. Startup screen showed TMobile still, even with the AT&T SIM card in it. I proceed to flash the A526U1OYM4CVB2_ATT that I found from Sammobile. Was hoping someone had just the "U" version but I couldn't find this anywhere. When doing the flash, I used the Home_CSC file (I had to download a patched version of ODIN as it was stuck as setting up connection) and when it finished it would just keep going back to the download screen on the phone and I freaked out. I did some more research and decided to flash again using CSC instead of Home.CSC (I did a backup using smart switch on my PC luckily). This WORKED! I'm guessing because the software version he was on was different than what I was trying to flash too so maybe this is why I needed the CSC for a clean flash (there was no user data file that downloaded from SAMMOBILE).
Now, calls are working on my son's phone again! AND his service provider software version now reflects ATT vs TMB! Man this has been one heck of a journey lol. I've seen numerous forums on google of people having the same trouble with me, their BYOD devices not working. Seems a flash of U1 worked for me, so hopefully this helps others out there!
I purchased unlocked ATT Tab S7 5G and I'm to remove everything with ATT since i'm using T-mobile network. I install T-mobile rom through Odin but only thing that was updated is from Android 11 to 12. I'm trying to remove ATT bloatware and wanted T-mobile startup screen and T-mobile standard apps. After everything install correctly from Odin, I can't get ATT out. Servie provider software version is still showing ATT. Am I doing something wrong?
Ok, so I have the SMG991U and almost every time it's in 5G I have no internet: it feels almost as though there is no date.
Tried poking around and I can't find anything but I'm sure I can't be alone. I think I had the issue with 12 (hard to say as I was carrying two phones at the time - one work one personal). Now that I'm down to one phone and this is my primary, it's pretty damn annoying (to say the least).
There are places where 5G is working fine, but most of the places when it's on 5G it's as though I have no coverage. When it rolls into 4G it's flying.
If I could set it to run 4G only that'd be great BUT there is no option for that. Any suggestions?
I'm running Android 13. All current updates. Baseband is G991USQU5DWa8
Try this dialer code and report results.
It lets you disable 5g bands. The app won't work probably, it was messed up before 13 came out, try it out and let us know!

This is another way to choose LTE bands but a little annoying." .
Btw since you're on u5, you could roll back to the one from May 2021, i used the T-Mobile cvdb version. It lets me use that app to easily switch bands as a few bands are worse than dial up in my area

You can roll back... The u5 of your current version means you can roll back to that one I linked which is also u5. After doing this,
Also remember to adb disable the update app
( com.wssyncmldm )!
If it were u6, you can't go to a u5 firmware.
I forget what that's called, some kind of revision number. Older ones could be rooted and use custom roms.
