I would like some help updating a Note 8, SM-N950F. Before I attempt anything I want to better understand a few things.
1) I see people mentioning different boot loaders, version 5 etc... Do I care what version I have?
2) The device was purchased from Australia and has Vodafone AU software and it's currently being used in the Philippines
Can I change it to XSA to remove any Vodafone crap?
3) I see mention of multi CSC firmware, is this official Samsung firmware and what exactly is it.
At the moment neither Samsung Pay nor Google Pay will install on the device, perhaps because neither are supported in the Philippines, any thoughts on this?
This is what I am hoping to install

After updating to PIE, Phone started to lag, swipe and navigation front and back does not respond in 1st few swipes. Batter train, Rear camera Seflfi option removed.
Boot your device into Recovery Mode and wipe the cache partition. That should resolve your software issues. With regards to installing the OS from your native country. Just check that the model number of the OS matches that of your Device. If they match then you should be fine.
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.

I would recommend using Frija instead, as it's probably faster, but the above is an alternative as well.

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).
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.
I have some experience in flashing via Odin having done it on previous Samsung devices but I am having all sorts of issues with trying to do this.
I have a Tmobile S21 Ultra 5g and just switched to Verizon. I am trying to flash the firmware to unbranded (XAA if I have read correctly) but I am getting errors. The first error was SHA256 which I read was because I needed a patched Odin. When I switch to the patched Odin, and I have tried both 3.13.1 and 3.14.1, it goes for awhile and fails. I am unsure whether I need to root the device to switch between carriers or try something else. I am unsure if I want to root it as I may eventually want to trade in the phone.
Do I have any options? My main issue is with wifi calling as I am at times in areas where the signal is terrible but may need to make calls. With the switch from Tmobile to Verizon it appears that is not working.
Hello! good morning, I have a Samsung Note 8 SM-N950U, which I wanted to install a custom ROM to get out of android 9, the problem is that the OEM unlock option does not appear on my device, I tried to change the date and update but It has not worked, I tried to change the CSC of ATT that comes by default but when using SamFW it tells me that there are no other CSC for my device, even on the web page, there is no solution for these problems or a way to install a custom one ROM, if someone can give me an answer I would greatly appreciate it.
Have you considered buying a rooted version of this phone on ebay or asking any people that sell rooting services on ebay?
