Hello!
I need to fix this issue it's ****ing annoying to be honest. So I have an ATT S9+ and after the Pie update my phone NEVER HAS FULL SIGNAL! I've even went as far as standing under the cell tower and nothing. I was on the CS7 and updated to the CS8 via Odin and the problem PERSISTS! When I was on Oreo I didn't have this issue, this problem started right after I upgraded to Pie.
I'm want to Downgrade or switch this one to TMB but I'm afraid of tripping knox or locking the phone to TMB. (It's code unlocked).
I really want to fix this issue. It's very annoying.
I know your frustrated but the answer won't change if you make a new thread asking the same thing as your old one...
Also standing under the cell tower won't give you realistic results. While capable of sending/recieving signals in a wide area they are not aimed at (or pointing) downwards at the tower base.
Flashing from G965U firmware to G965U1 firmware will not trip knox at all because your flashing official firmware files. I myself have gone from Sprint firmware to the unlocked firmware (G965U1) and to Tmobile firmware without any knox issues.
As for downgrading this is where your out of luck unfortunately. Downgrading is not possible because of the bootloader version your using. Specifically CSC8 uses bootloader version 4 and the last oreo release uses bootloader version 3.
You can only flash firmware that has a bootloader version that is the same (or higher) then what is installed on your phone.
TBH I would contact your cellular provider and ask them to look into the issue. Maybe they can do something to help resolve your issue.

Hey! Thank you for the info! I tried with another sim card from another carrier but the issue remained. I'm going to try to flash everything again with another version of odin and uncheck the auto-reboot option so that I can factory reset from the recovery after its done.

By any chance, do you know where I can find the stock ATT files? I can't find the anywhere.

Sorry unfortunately I do not. I haven't been able to find them myself when I used my S9+ on AT&T before switching to T-Mobile...
When I was with AT&T I had just used the G965U1 firmware since I would not have gotten access to any VoLTE and etc that required an AT&T whitelisted IMEI (to be provisioned for the features) and my phone wasn't an AT&T branded phone (since it was originally from Sprint).

So I was wondering if this is possible. My phone (running lollipop 5.1.1) is locked to a carrier but I was planing on flashing an unbranded 6.0.1 (from Italy). Marshmallow will eventually come to my country but I just can`t wait anymore. Will flashing this firmware brick anything ?? I am well aware that the phone will remain locked to my carrier, but is anything else going to be affected ? Anyone had a similar experience ? Your answers are really appreciated.:highfive:
Depends on the phone. Generally, if it is locked to a carrier then other firmwares will fail when trying to flash due to other differences such as the modem/baseband. There are exceptions, but pretty sure they are few and far between.

Thanks for your answer. It's galaxy a5 2016. Better not to touch anything. Don't want to mess is up within just 2 months after the purchase.
Is it possible to flash SM-G965U (T-Mobile) unlocked with SM-G965U1 stock unbranded (CSC: XAA) firmware?
If possible. How.
Pls help.

Yes. It is possible. But what are you trying to gain? TMO is one of the friendliest carriers to Samsung unlocked phones. You already get VoLTE and Wi-Fi Calling. VVM is available via Play Store app. That's probably the one carrier where I would never consider flashing branded firmware.
If you really want to do it, just flash U firmware with normal (not HOME) CSC. You can get it from lots of places like SamFirm or the various firmware websites.
Be sure to use the 3B patched 3.13.1 Odin found elsewhere on XDA.
Thanks for the information. I have unbranded my SM-G965U to SM-G965U1.
OK so I have a T-Mobile SM-G965U. I can flash the room and get a different rom on the phone? I though that I had to root the phone in order to install another rom.
Is there a rom that focuses on Tethering my phone data, under the phone datas apn.
One thing I can't figure out, there are so many developers, but there hasn't been a solid app , that can bypass signature checking and use the phone native hotspot feature under the phones data APN not the hotspot APN, so that it hot spot data comes up as phone data.
There has to be someone lol

You certainly don't need root to run a different firmware provided by Samsung for your hardware model. To do anything else, ROM-wise, you do need root. That doesn't exist for this model. Something like hijacking the APN in the manner you describe requires root. Your only hope is an app like PDANet that consumes phone data and provides it through another means like USB tethering. I think they have some support for Wi-Fi as well, but read up on that.
It's been forever since I've been here, missed this place. I am practically a noob now.
Here is my scenario:
I have a Verizon-branded S9+ / SM-G965U on the firmware/baseband G965USQ3BRK2. It is paid off, assured it is carrier unlocked and has also never been modified, pure stock. I'm looking to switch carriers from Verizon to another service. It's also my understanding that Verizon phones are a pain in the hiney and there may be issues with data, features, and other nags and warnings because a non-Verizon SIM is in use. Had an S5 that worked on other carriers but was a nightmare to configure.
Will I be condemned to a similar nightmare of nags and warnings, or will it rebrand it's self and allow me to receive OTA updates on the new carrier? Just not sure of what my options are, the search results yields conflicting information where some had to flash some firmware and others didn't.
Any recommendations would be appreciated.
I converted an unlocked Verizon S9+ to an unbranded, unlocked device, using it on T-Mobile and couldn't be happier with it. You have the option of flashing your own carrier's firmware or the factory unlocked, and it will improve your situation, no more SIM card notifications and all that.
P.S. I was in the same situation as you, used to be on here all the time but felt like a noob all over again. But a super helpful member here guided me through the process and it was completely painless, one quick flash with Odin and it was all good.

Welcome. Looks like there's some instructions here: https://forum.xda-developers.com/ga...icial-stock-firmware-thread-samsung-t3764479. However you will want to make sure you find the patched version of Odin to get past the fact that you are flashing a different firmware than is currently on the phone. And you will want to flash G965U or U1 firmware, that also has a 3 as the fifth number from the end, just as the firmware that's already on your phone.

Thanks for your help and for answering the questions.
Is there any benefit to flash U1 or would just U work?
Would the firmware downloaded using SamFirm work with that version of ODIN you linked?
Do I have to go through a rooting process and install TWRP prior to going ODIN on my phone? Or can I just go into download mode on my device, click yeah about a custom OS, then do the ODIN bit?

The U firmwares are those from carriers and the U1 is from the factory unlocked unbranded variant. so it's up to you if you want your carriers own firmware or just a generic Samsung version. If you need Wi-Fi calling and or volte, there might be a better chance of it working with your carriers firmware but the unlocked firmware does a good job with that as well, I have both of those features working perfectly with the U1 firmware and a T-Mobile SIM. Just make sure to use the CSC as opposed to HOME_CSC, so that your phone is fully wiped and configured for your sim card. I will say one advantage of the unlocked U1 firmware is free built-in caller ID ?
No rooting necessary, in fact it's not even possible on the US models, so just boot into Odin and flash the firmware using the patched version of Odin.
I'm looking for the latest USA factory unlocked firmware for the Stylo 4 (KDZ file), does anyone know where I can find that? I have looked everywhere I can think of and everyone has carrier specific firmware, but not the one I am looking for.
The specific model is LMQ710ULM.AUSABK.
The IMEI is: 357183090498307

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

Hi there,
You can try this website.

or

since your phone is network unlocked I think it might be safe to reinstall the firmware.
However, if you have your doubts feel free to search it online or ask LG directly.

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.

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

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!
