Hi,
I followed this post to update my Note 8 to Oreo. I didn't read it carefully enough to realize that its firmware is N950U, which brings all the good bloatwares and carrier firmware. Now, I would like to revert back to Nougat 7.1.1 with stock/pure Samsung firmware. Before messing my phone up, the baseband version was N950USQU1AQI5. My phone's carrier is XAA (the phone is factory unlocked). I have looked everywhere to find this firmware but the only one I find that is XAA is N950U1UEU1AQI5, which is for the U1 models not U (mine is N950UZKAXAA).
Can some one PLEASE help me get rid of Oreo and this carrier firmware and restore my phone to the original firmware it shipped with?
i think Oreo might have the bootloader v3, so you probably cant go back to what it shipped with (bootloader v1 or v2). You might be able to flash BRA5 and whatever was right before it (which is 7.1.1) because that did have the v3 bootloader.
I think U1 is for the unlocked model, so I'm pretty sure thats what you'd want to be flashing.
1. Download SamFirm
2. put in "SM-N950U1" for Model and "XAA" for region
By the way, I think this is the wrong forum for the Note8
I'm sorry, i don't know what you are talking about.
Any chance you could help?
Hi,
I have a Samsung Note 8 Tablet, GT-N5110 that's stuck on the Samsung logo.
Any chance you could help me revive it?

Hi All:
I followed the "Canadian W XAC Firmware" thread and have been very pleased - except that I have not gotten any updates since the April 1, 2017 Security Patch and the original XAC firmware available (QDE). A screenshot is attached and can be seen below.
This was originally a locked AT&T device that my company bought for me, right now the phone is showing XAA/XAA/ATT. I'm not really concerned about that - it's working fine as a device on TMB. I just want to make sure I'm getting the updates!
I guess this puts a couple questions into play:
Is there a difference between SM-955U and SM-955U1 hardware and/or firmware? Mine is currently on 955U, but it seems like they're fully interchangable - and the unlocked XAA is only under 955U1, as far as I can find.
Since I'm not concerned with TMB's features (which I've actually been able to activate in part anyway through the "IMS Settings" function), is there any danger in flashing the XAA (955U1) firmware?
If this is possible, can I flash the 955U1 firmware over the current firmware without a factory data reset? I'd rather not have to set up everything again.
Thank you!!!
Same issue here. Bought VZW s8+ originally, then flashed 955U1, then flashed TMB CSC. Now the string reads TMB/TMB/VZW. Not getting any update.

You'll never change the last one to TMB. The last code is hardwired into your device in the EFS folder and cannot be changed without root. It only shows what variant you originally received and should have no effect on updates, as far as I know.

No, there's no danger in flashing the XAA U1 firmware. There's several threads that show you how to do it, but it will wipe your device. Use Smart Switch to back everything up to your SD card. Between that, Samsung Cloud, and Google backup, you won't have to set much up again.
Once you've flashed the XAA firmware, you put your T-Mo SIM card in, and it will give a message stating it's switching carriers or something and reboot. You will still be on the unlocked, bloatfree firmware, but it will change your CSC string to TMB/TMB/ATT (the last code can't be changed), and you will have all the T-Mo carrier features except for video calling and RCS texting. If those are important to you, then you can always flash the T-Mo carrier software, but you'll get the bloat with it. (not much bloat on the T-Mo software).
As far as updates, everything I've read said you will receive updates OTA, but I didn't stay on T-Mo firmware long enough to find out. I just switched back to the original XAA firmware, and we haven't received a July update yet.
Something's not right here. Your model name should show as "SM-G955U1". Yours does not - yours shows SM-G955U still. If you want to be on the unlocked firmware, just search here on XDA for the princecomsy odin and download the latest firmware for the unlocked model and flash it. July security patch still isn't released, but having come from the unlocked S7e I can't say I'm surprised.
I don't know why you would need to follow any XAC thread to flash the unlocked firmware - all I did was use the modified odin and flash the unlocked firmware on my TMO S8+. Got the 1st OTA (unlocked U1 OTA) 1 week after flashing to U1.
There's a bunch of misinformation on how to change software versions. There's no reason to change anything with the carrier/region info (XAA/TMO/XAC, etc). As long as you are using a snapdragon S8 you can flash any (snapdragon) carrier firmware using the modified odin.
Hello All,
Recently I was able to flash my US AT&T branded G960U to the Samsung unbranded U1 version. After I did that, I flashed my phone using an official TMobile Rom, Oreo I believe. At the time, the boot loader was not locked.
Today I tried flashing back to the Samsung U1 firmware and it keeps failing as I believe that my boot loader is now locked which may have been caused by the TMO ROM.
When I did the flashing, I used the Modded Odin v3.13.1 Raymonf version. I tried the exact same steps tonight again and no luck. I tried on two different computers, have the drivers, files, etc.
Any known work arounds or fixes? I want to go back to the U1 version so I can upgrade to the Oreo 8.1 due to alot of bugs in Oreo 8.0
Thank you

Have the same problem here
The reason you cannot go back to u1 firmware is b/c the att and t mobile firmwares are newer and updated the bootloader to v2 hence you can't go back to the u1 firmware which has a v1 bootloader.
Sent from my SM-G960U1 using Tapatalk
Yeah I think I'm stuck too, however I don't mind as all the t mobile bloatware was able to be uninstalled and it's very responsive. Seems as if arc6 (tmb, 960u) is very fast and doesn't have any of the hiccups I noticed on the Canadian firmware (Telus arc1 seemed better but not as new as arc6 and also a one month older security bulletin).
I'm ok with being stuck however, we just need a U1 firmware with the v2 BL if I'm not mistaken.
How do you tell what version bootloader you are running?

I don't know, I just assume the may security update has it.
Forth character from right side is the bootloader version.
I've read that the Galaxy S9 hardware is identical for all carriers in the USA.
If I bought a factory unlocked Galaxy S9 can I flash it to the carrier I am using (Verizon, Sprint, T-Mobile, AT&T) to enable carrier specific software and features? Can I flash it back to the unlocked firmware?
I already see a thread about flashing the unlocked firmware to carrier models so I am assuming there are no issues there.
Can one carrier model be flashed to another carrier model?
No, bootloaders are different, with the S7 there was an unbranded U firmware that was compatible with most of them, unlocked firmware will be that one for the S9, but no you cannot just flash different device firmwares to the wrong model
I was able to flash the ATT rom onto my Verizon S9. I got a VZ s9 from work but I'm on ATT. For the most part it's worked great, I had done the same thing previously with a Galaxy S7. I say for the most part b/c I am on here tonight to post a question myself about the fact that I'm getting a delay with MMS messages. I imagine it has something to do with the APNs I have setup, but I can't seem to figure it out.

Did you have to flash to the U1 software first?
I do think that is what I ended up doing... tried to go directly first and it kept failing. Got fed up and decided to just try and put the bone stock rom on it, and that went on really easily.... so after using it like that a few days I tried to drop the ATT rom on it and it worked without issue.

Yes, but you need to go to the u1 firmware 1st then to the other carrier firmware. Also make sure you avoid the newer firmwares with the new bootloader, as the unlocked model and certain carrier models don't have the new bootloader.

That'll be why I still thought that then, coming straight from the S7 > S9
Had many members flashing the wrong firmwares thinking they could do that and bricking their S7s / wondering why ODIN failed

I tried downloading vzw firmware G960USQS3ARI6 to my unlocked sprint s9 and still not vzw flashed. want to do this so can have voice over LTE. Any other steps im missing? flash went through but still sprint
As soon as Firmware ver. 3 came out for the G960U1, I was able to flash it to my Sprint G960U and finally have VoLTE, WiFi calling and stable LTE for MetroPCS. Used samkey to unlock it from Sprint. My phone is actually performing much faster without all of Sprint's bloatware hogging my RAM and storage space. I can confirm that OTA updates still work the same...I received September's security patch (current) with no problems. Device is still official status and Knox hasn't been tripped.
A lot of people think you can just flash the carrier firmware of your choice and boom, it works...I had the same thought process....that's not the case. You have to make sure that there is a matching firmware version for the carrier you want to flash to, as well as make sure the G960U1 firmware version (the unlocked version of the S9's software you have to flash first before even carrier flashing) is the same version of what is installed on your phone now. It's easy ya'll......just READ lol.
I'm in love with my phone again thanks to XDA. ?
HAPPY FLASHING!

Hi, I got one unlocked G960U1(G960U1UES3ARI1) and downloaded new fireware(G960U1UES3ARI1-SPR) from sammobile, but after flashed SPR ROM successfully, the info on the phone still shows XAA, anything I missed here? Thanks!

Well first off, you have the unlocked phone. I don't. My G960U is originally from Sprint, so I'm not sure about carrier flashing regarding the G960U1. I thought it was supposed to provision itself after you put the sim in, and the associated carrier apps will download since it's the unlocked model...but I may be wrong...

I know so many people have already answered your question from some saying No to others saying Yes but you need to Install U1 first and Bla Bla Bla.
I want to give you one specific answer: With S9 you can any Carriers firmware you wish or even Unlocked phone's firmware. You will never have any issue. And you don't ever need to flash U1 or something else before changing carrier firmware you can Flash from ATT S9 firmware to VZW S9 firmware without any issue. You can also flash from U to U1 which is from Carrier specific to Unbranded/Unlocked but only hiccup is original Odin will give you SHA-256 error, which is normal because you are flashing U1 firm to U device or vice versa. This error can easily be resolved by used Patched odin that disabled SHA-256 check. And trust me you will never have any issue.
You will never want to do this but I have gone as far as mix-matching U and U1 firmware together as well. Like flashing AP, BL and CP of U device but flashing CSC of U1 device. and it still works.
hey there, a little late to the party, having trouble with going from a Verizon to a Sprint, even by way of U1. I can't get any of them to work. And I've been told I have to go from VZW to U1 before I went to Sprint. Is that not the case? I'm having a hell of a time getting anything to flash, everything fails.

well, I tried to load the Sprint image from the VZW, no dice. It said it passed, but upon reboot loaded up the old Big Red (even with the Sprint SIM in it).
Anyone have any ideas? This is driving me insane....
My sm-N975U AT&T note 10+ has never ever received any updates.
It's currently at Android 9, N975USQU1AS12, security patch: September 1, 2019. Since I got it in 2019.
I see that the unlocked version SM-975U1 AT&T receives updates frequently and I can easily get the firmware online.
I've not even seen any Android 10 firmware for SM-975U AT&T.
So is it possible to flash SM-975U1 AT&T unlocked over SM-975U AT&T.
Or even just to make it US unlocked with no carrier so I can receive updates from Samsung?
You can flash the N975U1 firmware onto the N975U (and vice versa) so long as the bootloader is the same version (or higher) then what is currently installed on the phone.
Three things to keep in mind:
No way exists to downgrade the bootloader... So if you flash firmware with a newer bootloader and you decide you want to go back you will not be able too.
Bootloader version can be found by doing the following. Looking at your About Phone > Software Version look at the baseband version info.. Start at the far right and count 5 characters to the left (with the first character being the far right one). The number that is the 5th character in will be the bootloader version that is currently on the phone.
The USERDATA isn't always included with the U1 firmware should you desire the AT&T version of it. You should be able to find that in this thread,
For an example the red number is the bootloader version:
N975U1OYM3CTE7
For anything else this question has been discussed here a lot so you won't have any issues finding information about it.
So this will unlock the phone? Does the same go for the Sprint version?

You can flash the firmware from the N975U1 to the N975U (and vice versa). It doesn't matter the carrier, only the model number matters.
Just be sure to be mindful of the bootloader version.
Flashing the firmware from the N975U1 does not have any relation to the network/sim lock. For network/sim unlocking you will have to ask your provider to do this for you
The term (or name) "unlocked firmware" is derived from the phone it comes from.. The N975U1 is the carrier/network unlocked variant sold by Samsung.
so if i put the, U1 firmware to n975u and i'm out USA. now I will receive all the new updates automatically via OTA?
Excuse me, I am new to the forum, I have a question for you, I have an at & t SM-N975U, this at & t firmware does not update outside the USA, I am in Mexico, which firmware should I use, I want it to update automatically via OTA here in Mexico? t-mobile firmware or U1 firmware, I really appreciate your answer,
hello, my question is similar but regarding the carrier. My Note 10 Plus is AT&T locked, if I flash the SM-N975U1 over the SM-N975U, will that unlock the carrier so i can use anyone outside USA?
No. It won't. You'll have to have AT&T unlock it.

Hello can you please help me too
I'm super new here
So i have the N975U and i live in Europe and i don't get any updates cuz my Note 10+ is the AT&T version and now i want to change it to N975U1 so i can get updates from Samsung themselves.. from Sammobile i downloaded The N975U1OYM7GULD-(XAA) model and also N975U1OYM7GULD-AT&T model while the current one i have is N975USQS7FUI7 so both of them i think should work because they have the same bootloader so my question is since i want to get updates to which one should i flash my phone with? I heard the XAA is better because u get updates directly from Samsung themselves ( even when I'm in Europe ) and the AT&T version is also N975U1 but I'm not sure if i will be getting updates because now I already have the N975U ( probably AT&T model that's why I'm not getting anything ) So what do you think i should do?
I'd appreciate ur help
And sorry for my broken ass English hope you understood..

And should i use Odin patch or just the normal odin? I actually wanted to flash my phone with the Germany version but i don't know if it will work!!? ( You'd use odin patch you want to change region! ) so idk if it would work if i change it from N975U to N975F which is Germany model !!?
I just got a galaxy s10+ from a friend who was on Tmoblie so it has the Tmoblie loading screen and apps. I would like to revert it back to the firmware CSC code XAA so I dont have to have the Tmoblie boot screen and apps. He didn't buy it from tmoblie its from an insurance company so I am pretty sure its unlocked. The app "Phone Info" says that Firmware's CSC code is XAA and the active one is TMB. I have tried to put in the *#272*IMEI# code into the phone but it just gives me an error code.
Is there anyway to revert it back to XAA without flashing the phone? Will I void the warranty if i flash the phone with official firmware? Also if I have to flash the phone where do I find XAA firmware as I only saw carrier firmware on SamMoblie.
Thanks for any help and very sorry if this has been posted a thousand times!

Odin Files/Guides For S21
Flashing S21 Ultra t-mobile branded to unlocked? Hi Everyone, I am a new samsung owner. I recently got s21 ultra t-mobile branded. It is now network unlocked. But i wanted to have a clean bloat free phone so wanted to have unlocked firmware. As i understand it, i need XAA G998-UA firmware...
forums.androidcentral.com
And I used this very kind user on Androidcentrals help. The context of my question is not needed but I basically asked if I was choosing the correct files.
"Yes use the firmware from frija , you will also need prince comsey patched Odin which download from XDA website, this will factory reset your device for first time , choose XAA as region with model number from unlocked version. (He is refering to the model number SM-N975U1) Put the device in download mode and make sure using a good cable and try 7zip to extract the firmware,odin,frija ...then after extract the the firmware you going take for files Cp/CSC,Bl,Ap and put in corresponding slots in odin and flash"
