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.

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".
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).
Is it safe to change the CSC so we can use a Samsung image that's less bloated? My version has O2 apps installed and I'd rather reclaim that space for something else, or at least not have to look at it.

I don't know about other regions, but in the USA region, I beleive the SIM card will set the CSC for you, and not allow it to change. In some cases, even that doesn't work properly (I had to return a phone because it wouldn't switch). Maybe you have more control in other regions or with Exynos phones...
Just tried the key combo and no dice, got a message that said 'that function is not supported' or something like that. I asked a question elsewhere here - what would happen if I were to just flash a different Android 12 firmware version on this phone? Right now, the phone is O2U, would I brick if I used XAA (US)?
I don't know what key combo you're talking about. As I mentioned, in the USA region, the SIM determines the CSC. What type of phone do you have (Exynos vs Snapdragon) as this could affect things as well?
If you flash a snapdragon ROM onto an Exynos phone, I imagine you're going to have problems. I don't know if that bricks it, but I wouldn't be surprised if it does.

Yoooooo I'm going through same issue. Look you can flash any firmware Purdy much as long as the binaries are the same im trying to root a galaxy a13 5g from MetroPCS that only has two months activation in and its beating my ass. I was able to do some kinda unlock on it coz now it says device is corrupted dm-verity can't be trusted but I still don't have oem unlock displayed in developer options I've flashed t-mobile,Verizon,MetroPCS, and now I'm on Canadian firmware which is supposed to be unbranded but because MetroPCS has the network lock on it it hasn't mattered what I've flashed because I even had it XAA by flashing the a5150 csc tar file trying to root this funding piece of suit phone but to no avail.unless I get the network unlock icant get the bootloader unlock option,tried vbmeta image no verity no force encrypt every Magisk version boot image patched even tried different device with same chip and set up... impossible broski if you phone is network unlocked and you are able to unlock bootloader so you can bypass vaultkeeper/avb/secureboot/vbmeta/dmverity/prism.img....etc etc etc and with root access only then can you change and/or modify any part of a samsung device as far as my knowledge and experience goes

I just swapped carriers to Mint Mobile from Verizon. I noticed my Google and Samsung cloud backups were not working and found out it was because Verizon blocks them, so you have to buy their cloud service. I decided to flash the Samsung stock unlocked firmware (G973U1) to my Verizon firmware S10 (G973U). That fixed that problem, but when I check for software updates, it says the security update from January 1st 2022 is the newest update, but I know I got a security update around April 4th when I had the Verizon firmware. None of the firmware on sammobile for the G973U1 says it is newer than this. All the carriers listed here are the same. I don't know why you need different carriers selected here because it should be the same Samsung firmware right? I flashed the T-Mobile one because Mint Mobile uses T-Mobile network and Mint Mobile wasn't listed. Should I flash another carriers version of the locked (G973U) firmware and see if that works? Or should I just flash the Verizon firmware back on it? I also called Mint Mobile tech support and asked them if there was a way for them to push the update to my phone, or if that hadn't released that update on their netork yet, but they said that they don't do anything with the software updates and those come from Samsung.
U1 is an "unlocked" phone that can change carriers via CSC changes. In theory, just swapping SIMs should have switched you over to the new carrier (sometimes this doesn't work).
Flashing the U-version means it may not be the universal version that U! is... so it may not switch over properly. That's the first issue. But now that you've done that, it's kinda moot.
I'm not sure why you put a Verizon FW onto a Mint/TMO carrier at all? I would suggest a U1 TMO or Mint firmware to start with, and see if the CSC updates properly. When that happens, and if it switches properly, then the updates should work normally.
But, even beyond that, you could have just flashed an upgraded version of your ROM to get the update, saving yourself from all of this hassle anyway. Sure, it's not "coming from" the carrier (it never does - it's coming from Samsung usually, as Mint noted)... so you'd just bypass their issues.
Lastly, I will warn you about getting the latest (March) update, as this is Android 12. Many people have had issues with A12 on their phones due to incompatibilities, battery drain, etc. Personally, I'd hold off updating to A12 as long as possible (my and my-wife's phones are both still on A11 for this reason... January update). I just posted on a thread where a user lost GearVR compatibility on A12, and was asking how to downgrade... there are lots of such posts here...

I didn't flash the verizon U version firmware that was what came on my phone when I bought it. I flashed the T-mobile U1 firmware and it still didn't work. There is no Mint Mobile firmware. Where would I get the upgraded version of the rom? Most people I saw were recomending sammobile.com and the newest U1 firmware only had the January 1 security update. I had android 12 on my S10 before I flashed any firmware, and I didn't have any issues so don't mind running it.
You can get ODIN ROMs from many places. Sammobile is one, Samfw is another. To get latest firmwares, Frija or other such tools are faster because they can download directly from Samsung servers. The limitation is that those can only get the latest versions, not past ones.
Correct, there is no Mint firmware that I am aware of. Yes you should be able to get the TMO firmware, which is actually a TMB CSC. You can see that here: https://samfw.com/firmware/SM-G973U1/TMB/G973U1UEU6HVB2
With that in mind, you'll also see that the CSC version shows "OYM" which is actually a multi-CSC USA firmware. Again, these firmwares should change CSC based on the one shown by your SIM. For example, mine is an OYM ROM, which shows a CSC of TFN/TFN/SPR (first is what carrier the phone is on (Tracfone in my case... I'm using Total Wireless), second is what the SIM is, and last is what the phone was "born" with... that cannot be changed).
If you're running an OYM now (likely you are) then check the CSC... see if it's switch to TMB/TMB/xxx. If that hasn't happened, then that could be part of the reason you're not getting updates. Sometimes phones don't change (one of the 2 phones I got originally would not change, so I had to return it and get another... no idea why).
Note, to change CSC, you need to flash the "CSC" ODIN file, and not the Home_CSC file, as the latter will keep the existing setup of your phone. You can see more info on the difference here: https://www.getdroidtips.com/know-about-csc-home_csc/#CSC-vs-Home-CSC-the-difference
Bottom line, start by checking your current CSC... it should be TMB. If not, you can ODIN flash, with CSC (not HOME_CSC) and that hopefully will get you on the correct CSC. Note that this will erase the phone.
Alternatively, as I mentioned, you can download the latest FW, and just HOME_CSC flash that with ODIN to get you on the latest without waiting for the carrier to push it.
