is there a link to download the US Unlocked firmeware for SM-G998U1?
[Samsung Galaxy S21 Ultra] bANONYMOUS:
Does anyone know what XAR CSC is? There's an Odin .tar firmware floating around that's SM-G998U1 XAR. Not sure what that CSC is. I've only been able to find that it's US Unbranded/Unlocked for C Spire. But, if it's unbranded than wouldn't it just be the same as XAA?

I found SM-G998U1 XAA BUK7, but it says it's going to take 8 days to download and I have gigabit fiber, so it's not me haha.

Hey buddy is this the ODIN files for the U1 ?
[Samsung Galaxy S21 Ultra] bANONYMOUS:
Yep, these are official full firmwares to be flashed with Odin.
[Samsung Galaxy S21 Ultra] androidbuff123:
You can use Frija to download the latest firmware too. Use model SM-G998U1 and for CSC use XAA. For the US unlocked firmware. That's what I did. Frija is really convenient.
[Samsung Galaxy S21 Ultra] omek07:
I am wondering if they fixed the problem with the keyboard that I had with the beta. The problem that I had it was that the keyboard was pressing the enter button and I could not use the keyboard. I don't have that problem with the 3.1
[Samsung Galaxy S21 Ultra] Da Baron:
name it to update.zip if sideloading correct? I've done so on all 4 previous betas
[Samsung Galaxy S21 Ultra] Da Baron:
Just rename to update.zip and sideload like previous betas?

Thank you
[Samsung Galaxy S21 Ultra] dpw2atox:
I have an unlocked S21 ultra in the USA and I haven't gotten the update to stable yet, anyone know when it should be released? I am currently running the final beta release and havent had the update show up yet.
[Samsung Galaxy S21 Ultra] viktorgorgievski:
One UI 4.0 Update for Samsung S21 Ultra SM-G9980 ?​
[Samsung Galaxy S21 Ultra] Lucky_Charles:
Yes. But I would recommend using oding to flash the stable firmware. This way you will be able to receive OTA updates.
[Samsung Galaxy S21 Ultra] Da Baron:
So just unpack the zip then flash via Odin?
[Samsung Galaxy S21 Ultra] Lucky_Charles:
odin uses .tar files. follow the flashing guide I've quoted you in the last reply.
[Samsung Galaxy S21 Ultra] Da Baron:
Will do. Much obliged.
[Samsung Galaxy S21 Ultra] bANONYMOUS:
Are you officially on the Beta or using the files from here?

If you're not officially on it, you won't receive the OTA to stable, you need to flash it manually. From that point on, you will receive OTA's like normal once you are on stable. But unofficially on the Beta, you will not receive OTA's, even if the last OTA is to stable. You still won't get it.

However, both U and U1 OTA's to stable have been posted here, so you can just sideload which of those correspond to your device to get on the stable build whether you're officially on the Beta or not.
[Samsung Galaxy S21 Ultra] dpw2atox:
I'm officially in the beta, just have been waiting for the official stable update. I was curious if they had released the OTA in the states yet or delayed it to fix the refresh bug.
[Samsung Galaxy S21 Ultra] bANONYMOUS:
Must have been delayed cause both U and U1 OTA to stable are in here a couple pages back.
[Samsung Galaxy S21 Ultra] death365:
So if I Sideload the update I will not get ota updates???
[Samsung Galaxy S21 Ultra] yeltrah123:
You will still get OTA updates. You can download the firmware from Frija now since its out on the Samsung servers so you can flash via Odin. If you do decide to sideload and update that way that works as well. I'd recommend downloading and flashing with Odin though.
[Samsung Galaxy S21 Ultra] death365:
Thanks, was just confirming, I sideloaded a while now.
[Samsung Galaxy S21 Ultra] dpw2atox:
I got the OTA yesterday, it is BUK7 so not sure why there was a delay.
[Samsung Galaxy S21 Ultra] Wacky2bakky:
Just checked and got BUKF for T-mobile U. Still November security patch.
[Samsung Galaxy S21 Ultra] bANONYMOUS:
Here's SM-G998U TMB BUKF for anyone who didn't get the OTA.

Flash with Odin, use HOME_CSC to retain user data. It's just an update so you don't need to factory reset.

Always backup your phone first, just to be safe.
[Samsung Galaxy S21 Ultra] omek07:
Did you see any improvements or fixes of the problems ?
[Samsung Galaxy S21 Ultra] Wacky2bakky:
Everything seems good so far. I do know this update fixed the issue with the phone not running @ 120hz

I thought the same until seeing this interesting article, making the point that this is more a year of refinements for Samsung. That, in fact, most new features in Android 12 have already been offered by Samsung. It's more a year of Google catching up to Samsung than vice versa.

Great article-

FYI, I also have a mirror of all the beta OTA files released, with checksum files for everyone's convenience:

4.0 - Google Drive

drive.google.com

I will be keeping this folder up to date as the OTAs are made available, and it will always be a 1:1 mirror (no file renaming or editing, will always contain checksum for verification), and I'll also work on a nice summarised tutorial (for which I'd appreciate some help, as I only have a G998B, so if there's any unexpected differences between a B and U1 variant, I wouldn't know).
[Samsung Galaxy S21 Ultra] tjsooley:
FYI if you have a phone converted to U1 from another carrier. Putting in a t-mobile sim will not work for joining the beta even if the device is sim unlocked
[Samsung Galaxy S21 Ultra] SOGKush420:
You need an international sim card that can change your sim simcard number to a specific number according to what country you pick.. lycamobile is the one i used so i know thatt can get the job done and you need to clear the data from members and galaxy store too after that.. then country related store and members will load up... if not change your ip with vpn too and clear data again
[Samsung Galaxy S21 Ultra] tjsooley:
Wow really? Why does Samsung's beta page say a T-mobile US is supported?

I couldn't get it to work for G9980 keep getting the "adb: failed to read command: No error" and phone then goes out of adb mode and back to recovery menu and I can still boot normally so nothing's happening. Anybody know a fix?
[Samsung Galaxy S21 Ultra] goofwear:
ADB has not worked for updating ota's for me since the Galaxy s7 you need to copy the file to you phone to flash it.

How do I flash it after that?

[Samsung Galaxy S21 Ultra] harshad_kp:
have your tried again... were you successful... I too have 9980 HK model.
[Samsung Galaxy S21 Ultra] elliwigy:
not true.. i did adb sideload on my g998u1 and worked first try..

plus, how can you transfer to the phone when it has no extsd card?
[Samsung Galaxy S21 Ultra] elliwigy:
yes
[Samsung Galaxy S21 Ultra] elliwigy:
if u are trying to use an update file from g998u on a g9980 it will not work
[Samsung Galaxy S21 Ultra] elliwigy:
seems people forgot how updates work.. if you post a ota file you should list the device, starting firmware and the firmware you are moving to else it will not work..

for example i posted link for G998U1 4AUH9-4ZUID zip..

This means the following:

Device: SM-G998U1

Firmware I Was On: 4AUH9

Beta Firmware: 4ZUID

So the steps would be (f9r this specific example):

1) Own a SM-G998U or SM-G998U1

- since the zip is for G998U1, if you own a SM-G998U, you will need to flash SM-G998U1 firmware to it using modified odin (see next step for firmware info)

2) In my example (also was my case) my device was on G998U1 rev4 firmware 4AUH9. Therefore to use the zip you need to be on this same firmware. If you arent already then you would need to use modified odin to flash your g998u or g998u1 to rev4 G998U1 4AUH9 firmware else install will fail.

3) Download the zip (if you download directly from Samsung you'll get a bin file, just rename it to .zip if you want or if you have issues installing it named .bin).

4) Using adb, type: adb reboot sideload

5) Once in adb sideload, type: adb sideload update.zip

- Depending on what OS you are using, adb might be in your path, if not then have the adb binary in same directory as your update zip. If its in path just open terminal in same directory you have the update zip.

6) Let it update, it might take a while but should go through successfully.

If you are not sure what firmware you need to be on then you can open or extract the zip using an archive manager such as 7-zip and navigate to the update-script and open it in a text editor like notepad++ and you will see what you need to be on to start with.

The update-script has commands to do various checks so when you go to sideload it, it will check what device you are on, what firmware you are on, if firmware has been modified on the device, if zip has been modified etc. and if something doesnt check out it will fail. For example if youre rooted it will fail.. 8f you modify the zip it will fail.. if you try to flash a zip on a different variant or model it will fail.. if you arent on the starting firmware it looks for it will fail..

this is how its always been and is designed to not brick your device as well as security in mind i.e. cant pre root or change script to root device as it will break the zip/signature etc. etc.

I have the Canadian variant G998W. Is it possible for me to flash the G998U zip file? Because I tried and all I get is this error:

[Samsung Galaxy S21 Ultra] omek07:
Hello buddy thank you for your answer . Did they activate the esim in U1 or U version ? do you have any screen shot please ?
[Samsung Galaxy S21 Ultra] omek07:
I think you should flash first a U version from September which will wipe all your data. Then you should be able to flash the beta

Nothing yet, Until beta program begins officially in China or until releasing September security patch for G9980, there is no chance to have beta One UI 4 on it.
[Samsung Galaxy S21 Ultra] FlyingEwok:
The U1 rom is the US unlocked rom, don't think it is tied to any carriers.

If the September patch release on any of 9980 regions there is a chance to sideload the U1 Beta update.zip on your device or simply if beta start in China there is no worry about compatibility or any other issue!
[Samsung Galaxy S21 Ultra] bilalwarraich:
thanks man appreciate.
[Samsung Galaxy S21 Ultra] FlyingEwok:
This worked for me! (My original model was the SM-G998W and then I used Odin like you said and flashed SM-G998U1 with the rev4 firmware 4AUH9 then flashed the zip you provided)

Thanks!

One question though with the zip your provided would I receive OTA updates once beta 2 comes out?
[Samsung Galaxy S21 Ultra] klabit87:
Looks like nobody has the S21+? lol I am not able to get the beta or i would do it myself. Can somebody please try to get the link for the S21+? (SM-G996U or U1)
[Samsung Galaxy S21 Ultra] Lucky_Charles:
This worked for me. I received the september security patch a couple of days ago. I only had to sideload the beta update.zip
[Samsung Galaxy S21 Ultra] Atoman03:
I was able to use the update.zip with a SM-G988U Verizon by going to the SM-G988U1 firmware via modified Odin and then using the update.zip. Thanks for the link!
[Samsung Galaxy S21 Ultra] JG96EVO:
I have a Verizon S21 ultra also. Just curious if the beta has been working good for you? Just curious before I do it.
[Samsung Galaxy S21 Ultra] Atoman03:
It has been working just fine for 24 hours now, battery life has been the same. There were a couple of changes that I wasn't sure about like the Mobile Data at the top right looks different but that is just because it is the Unlocked firmware instead of the Verizon firmware. Let me know how it goes for yours if you do it.
[Samsung Galaxy S21 Ultra] JG96EVO:
Thanks for the reply, does 5g work for you? And if I wanted to go back stock, where do we get the stock vzw firmware from? All I saw was something labeled U1 vzw but my phone is a U version.
[Samsung Galaxy S21 Ultra] MaCroEdge:
I have G991U1. Sim Card Manager is present and was simple to scan in the eSIM QR code for AT&T. I didn't show any signal until I disabled the primary SIM and rebooted with just the eSIM active, then it provisioned and came online. Then I was able to turn the SIM back on and both work. It only uses the primary for data. It is pretty simple to change which card is primary.
[Samsung Galaxy S21 Ultra] Atoman03:
I am not able to test 5G since it isn't in my area. The stock firmware, I was just going to leave it as the U1 firmware since it is the Unlocked firmware and I personally don't care about having the bloatware that Verizon installs on here. You will have to use the U1 VZW firmware to even be able to use the update.zip as well
[Samsung Galaxy S21 Ultra] Darkbandit14:
I think I give up.. I have done everything that I have read and still it will not allow the update to go through, I keep getting the cannot read error.

[Samsung Galaxy S21 Ultra] death365:
You have to have the update.zip file in the same folder "platform tools" also if you are using power shell the commands are ./adb then the rest
[Samsung Galaxy S21 Ultra] Ackeem.Salmon:
It is in the same folder. So I have to also put ./
