I have a Samsung Galaxy S10, model SM-G973U. Last week it did an update and something went wrong and it got stuck in download mode. I couldn't turn it off or anything. I finally had to flash a SM-G971U1 firmware to get the phone back working again. Does anyone know where I can find the latest factory AT&T firmware for the SM-G973U? The US version.

That's the one I used, but the AT&T logo doesn't show anymore and some of the AT&T features don't work like wifi calling. I thought the 973U was the at&t and the 973U1 was the samsung version.
You may have to reset the SIM somehow. Often, when the carrier sees the same SIM, they don't check the phone for what it can do, so it assume Wifi calling and such doesn't work. ATT is notorious for being stupid about such things (I've read far too much of this type of stuff on other phones as well).
You may just need to call ATT and tell them it's not working... they'll check the IMEI, see the phone is correct, and then reset the settings. That's another possibility.
Also, you may need to flash the firmware with a full reset or something, so that the CSC can re-recognize, but that means you'll lose any data on the phone... so just be aware of that possibility. Bottom line, ATT should help you with getting things working again... it's their problem, after all (assuming it's a valid ATT IMEI phone).

Hi,
I recently bought a Note 9 (SM-N960FD) from Duabi and went back to Canada. Now Samsung Pay is not working here at all. It gives me an error message that it is unable to connect to server.
I have been looking for solutions around for the past 2 days with no luck.
What I reached is that I have to change the CSC of my phone (which seems to be a much more complicated process than just flashing a firmware with ODIN). And some suggested that this will be of no use as my phone is exynos and Samsung Pass will not work in Canada unless it is a Snapdragon phone!!
Also the model is different here in Canada. It is SM-960W (with XAC as the unlocked version).
What do I do? I want samsung pay to work on my phone. Shall I change the CSC and flash the Canadian firmware? Is it Okay to do that with the Canadian firmware designed for a different model (960W and not the 960FD)
Please advice.
Thanks
sammobile firmware to change csc
hello,
I was in a similar case when i bought my note 9. It was from Taiwan and I am from Spain.
I flashed the spain firmware from sammobile
https://www.sammobile.com/firmwares/recent/
and now my Samsung pay and other apps work natively. I was told by Samsung Taiwan that flashing other csc can cause incompatibility, so take that in mind because although it may not seem real, the different versions of smartphones have different hardware.
Research a little bit from the forums.
I had the sm-n960f/ds and i installed the software from the sm-n960f from Spain.
Also, install cpu-z so that you know well what chip is installed inside and more info that could help you to fix this issue.
This is only informative, I don't take any responsibility of any damage.

unfortunately you cannot flash different model firmware on different chip.
so ure stuck. the only way id see ure spay working again might be using a vpn and choosing one of the region phone is from. but id doubt this would be a good long term solution. but as a proof of concept, it might be nice to try.

Hi there,
I'm about to order a Galaxy S10 directly from Samsung since they are way cheaper than what my carrier sell them. But, when I do my carrier tells me that VoLTE and VoWIFI will not work on Android phone bought from other than the one they sell...
I've read a little bit and it seems that I'd have to change the CSC of the phone, I've chatted with samkey about the particular model and it's not supported, because of bit 4 or something like that. Anyways, I've downloaded samfirm and found the firmware for my provider "VTR" but it seems that all firmwares from any provider in Canada share the same thing because what is getting downloaded is a "VLS" and the CSC one is "OYV"

I need advise to modify the firmware or options in my new phone to make it look like it's coming from my provider (Videotron) and when I insert the SIM (with NFC+VoLTE) in it I have a chance that the option will be available.
I'm an IT Specialist, I've flashed my old S7 with those files before with no luck. It's the same story with the S7, bought from Samsung, initialized with an other provider SIM though. Then flashed the phone with my provider CSC got a proper SIM card and I had them enable VoLTE on my line, but the option never showed up. I'd like to be able to enable it on my new phone, that's why I'm doing research before getting my hands on it.
Can't you just download the video tron firmware and flash it to the phone with Odin?

I sure can, just wondering if it's gonna work since last time I did that on my S7 it didn't work.
I downloaded the firmware using SamFirm v0.5.0 for 2 providers, VTR (Videotron) and RWC (Rogers) two very different providers and I compared the two CSC files using sha256 and they are both identical (I didn't test the big 5G files though, but they have the same exact file size). So I'm wondering if I'm even downloading the right thing now. It's probably multi CSC. Then does the stock Canadian Samsung firmware the same as the one I'm downloading?
It should tell you on sam firm what firmware you need to download or if you're running the current stock firmware, then just look in settings to see what base band you're on and go from there. I wouldn't flash rogers if you have another carrier, that may cause some issues.

Thanks I'll look into it a little more when I actually receive the new phone from Samsung. I wasn't going to flash a Rogers firmware, I downloaded it to do a compare and check to see if they actually are identical to VTR ones and they seem to be identical, at least the CSC files are.
many folks have found that buying direct from samsung doesn't guarantee the phone will work.
several on xfinity mobile found out the hard way.
I am pretty new to Samsung's and their csc system.
I have an Australian SN-G781B with OPS csc (Australian carrier)
Just wondering if its possible to change csc to XSA (generic Australian region) to ensure I get more timely updates that won't require carrier testing bs.

flashing a CSC is super easy. put your phone in DL mode, fire up Odin, load the file and flash the HOME_CSC, not the CSC. HOME_CSC will allow you to flash firmware without factory resetting it. sammobile.com/firmwares to get the FW you need and be sure to use either SamFirm or.... god dangit... i cant ever remember the other programs name. Anyways, SamFirm allows you download the several GB file literally 5x faster and its a 100% trusted .exe. Anyways, get the U1 version of the firmware and flash it, boom... unlocked phone. Might need patched Odin to get around the phones security that usually blocks firmware flashes like these
The question would be if samkey software supports changing of S20 FE 5G's CSC to other regions (e.g. THL for call recording)
If someone finds a CSC setting, flash-able to the US unlocked S20 FE, which enables eSIM and call recording, yet doesn't impact the available 3G/4G/5G bands, please share the info. Thanks.
I just did a successful CSC change on my USA Unlocked S20 FE 5G without wiping the phone, maybe the info can help you. See my new thread: https://forum.xda-developers.com/galaxy-s20-fe/help/successfully-forced-october-update-t4183325
However, you may need to do your own research on the proper CSC to use in your region. I simply wanted to swap my CSC to XAA so I could force an update is all.
Dont bother as I have xsa and have not received any updates yet.

I don't have the device (yet?), sill trying to decide if i want to pull the trigger on it, or get Pixel 5 instead. The eSIM is one heck of a convenience feature when traveling, and i'd really want to know if i can get it working BEFORE actually paying for the device. Right now, sadly, i assume a "no" as an answer on that

Correct, I have the US unlocked version and trying to activate an eSIM from US Mobile for a trip to Asia soon. So far, no luck. For whatever reason, Samsung is disabling this feature in the US for now....

Google it on the original S20 series, and you'll see the same story. For example, here - US Unlocked Version ESIM Update? - Samsung Community - 1147639. Guess we can spell the "for now" in the quote above as "for good".
Hello,
Forgive these noob questions.
I live in France and I bought a galaxy S10.
It happens to be a US model: G973u
I installed android 12 by flashing G973USQU6HULD, G973UOYN6HULD carrier unknow (DSH)
It stays with the T-mobile overlay
1 Can I flash it with firmware for G973F?
2 Otherwise, if I flash with USA carrier (USC) will this overlay disappear?
3 In this case should I flash everything or just the CEC file?
Thank you
No, you cannot flash with 973F, as that phone has different hardware (Exynos CPU versus Snapdragon).
You can try a different USA carrier, but I don't know if it will be very different. I don't know what "overlay" you're talking about, but many carriers do various things to brand the device, and I'm not sure which ones do what.
You may consider flashing with U1 firmware, which is the "unlocked" version. In the US, this then identifies which carrier you are on, and then activates features specific to that carrier when it sees the correct SIM card. Since you're not going to have a US carrier SIM, it should stay in "unknown" mode (XAA). I just helped another user in Europe with an update for his phone, that happens to be stuck in a similar state. He used an ATT U-ROM, because that's what he already had... I don't know if he had this "overlay" you're talking about.
You could even see if there is a carrier that does match what you have in France, and see if you can find a ROM for that. There is a decent list of CSC codes here: https://www.droidviews.com/how-to-change-csc-in-samsung-galaxy-phones/
I'm not sure what "CEC" file you are talking about on your #3 question.
Hi Schwinn
Thank you for your answer
I wanted to write CSC not CEC
In overlays, I was talking about T-mobile's splash screen and non-uninstallable apps.
Pardon my English
Hi
I am the other european guy with the G973U ATT. I dont have any overlays or ATT Bloatware installed, even though I dont have a U1 software. How is the flashed software Version running on your device? How is the battery life? Did it change after the flashing? Im curious cause I also have the Snapdragon model of the s10 and the battery life is not bad but i expected more for Snapdragon.
Hi Lessy,
It's a new equipment bought at professional seller in Rakuten.com I flashed it via ott to obtain android 12 and changed the firmware with 'unknow carrier' but it didn't made any difference. I will try with 'USA' carrier
@Fast_Lessy You made a good point on your other thread... that maybe the ATT version is causing you the issue. The theory is that if the carrier isn't recognized, it could be working harder to maintain a connection or something. Unfortunately, for you in Switzerland, the S10 is normally the Exynos, so the ROMs that support you officially are going to be for that CPU (G973F variant of the hardware). So, you can't use those ROMs on the USA version (Snapdragon CPU).
I think you may consider trying the XAA version of the ROM, as this may be more flexible to work with your carrier. In the USA, this version will "adapt" to the SIM as needed. In your case, it can't adapt to your carrier, because it doesn't know how to do that, but maybe it would remain more "world compatible"? I'm just guessing...
Assuming you want to try that, you'd change to the U1 version (G973U1) and get the XAA ROM. For example, these: https://samfw.com/firmware/SM-G973U1/XAA
I'd suggest sticking to A11, but you can certainly try A12 if you want. However, note that you might want to wipe the phone before doing this, because it may be different from the "U" version you have now.
Note, the U1 is what I have on my phone now. This shows up as Provider Version SAOMC_SM-G975U1_OYM_TFN_RR_0009 (I'm on an S10+, and I'm on CSC TFN/TFN/SPR. The OYM means it's the "XAA"... not sure why this happens, but that's what I have heard. OYN means it's the multi-CSC ROM for USA, but on the "U" version, instead of U1.
As before, the risk is yours... please don't blame me if things don't work out, but I will help as much as I can! And always backup anything important to you before doing anything.
I tried to flash G973U1 without success (SHA error) so I flashed android 12 with "USC " CSC for G973U after a total wipe.

The phone works but I still have the red T-mobile start image and the T-mobile application.
It seems that all firmware are like this. I stop searching
If you did an upgrade install with ODIN, yes that will likely happen since upgrade won't "remove" the previous settings and setup. You would have to try a clean "refurbish" install, and that might clean that out.
Of course, I assume you don't have a TMO SIM card either, correct?
Yes I installed with odin after wipe user and cache in recovery mode. I have a SFR (french provider) card.
Hello all,
I have an S21 Ultra that was originally a T-Mobile device, was unlocked, and then flashed to "factory unlocked" 998U1 firmware as found on this forum, and used with AT&T. Since the shutdown of their 3G network, however, I have been unable to make or receive calls and the "Enhanced LTE Services" option under Network Settings is unavailable to me. After a ton of fruitless troubleshooting, AT&T says I need new firmware. I was going to install the AT&T-branded U1 firmware from SamMobile in hopes that would solve my issue, but whenever I try to go to the bootloader to flash the new firmware, the phone just boots normally instead. I can't seem to access the bootloader, even after factory resetting the device.
Samsung has offered to reflash the device back to factory settings, which would make it a T-Mobile device (unlocked, presumably?) again. Does anybody know if the AT&T firmware linked above will work with VoLTE on their network? Would I be able to flash to that again to get the bloatware-and-branding-free experience while still having the device work as a phone?
Thanks for any knowledge or help, I've been beating my head against this thing for nearly a month now.
I may have solved my issue! Fingers crossed, will confirm tomorrow once I'm sure, but so far, here's what it looks like:
I had installed what I believed to be standard Samsung U1 firmware which I assumed would work regardless of carrier - I believe from this thread but don't quote me on that. Regardless, it was unbranded. When AT&T shut down their 3G network, I was hosed because the U1 firmware I'd installed did not have VoLTE/"Enhanced LTE Services" or anything like that as an option I could enable. After a ton of time, I finally figured out that it was a firmware/baseband issue.
So I downloaded the AT&T "branded" U1 firmware from SamMobile but the recovery menu wouldn't let me access the bootloader for as-yet-unknown reasons. The instructions to hold volume-down+power got me into the recovery menu, but that was as far as I could get. However, Iater discovered that with the device plugged into my computer, I could boot it directly into the bootloader by holding volume-down+volume-up. With that accomplished, I installed the AT&T U1 firmware and viola! VoLTE options were available, and with my SIM card installed I could finally make calls again!
Will use it all day tomorrow, see how things go and report back.
Could you help me i am basically in the same boat! What firmware for at&t did you download and where? Thanks!
I used the firmware at this link: https://www.sammobile.com/samsung/g...M-G998U1/ATT/download/G998U1UES5CVCB/1627452/
I couldn't get to the bootloader from the recovery menu, but could by using both volume keys simultaneously while the phone was powered off and plugged into the computer. Good luck!
There's a good thread on Reddit regarding CSC issues when flashing branded S21 devices to U1 firmware. Essentially, on the S21 series, particularly for TMB CSCs, it tends to be difficult to get the correct CSC software for VZW and ATT, particularly after flashing to U1 from U firmware. See this,
