I have SM-G998W, used patched Odin 3.13.1 when the phone first came out to convert it over to SM-G998U1 XAA, and I am on the latest OTA update to 4AUH9. But I was getting an error at 47% like others have reported.

My fix was to just do a factory reset. I wiped my phone completely, set it back up with no accounts so it's just a fresh, account free, install of SM-998U1 XAA 4AUH9. Once I was back into Android after the setup screen, Go straight to settings, software info, tapped build number 7 times, back, back, developer options, enable USB Debugging, Tried it again and it works fine.

I'm on Windows 11 22463, so to setup platform-tools system wide so it's easier to use like on Linux, I go to Settings, System, Advanced System Settings. From Windows 10, you go to Control Panel, System, Advanced System Settings (on the left bar), but from that point, the steps are the same between Windows 10 or 11.

In the window that opens up, go to Environment Variables, and in the System variables section, click on Path, and click edit. In the window that pops up, add a new directory which leads to the platform tools folder.

Now ADB is system wide so you can just open Windows Terminal (PowerShell or CMD), and when you type adb version, it just works. No changing directories or anything.

No need for ./ before commands as others have reported.

Once that was done, simply typed in adb devices, made sure the phone comes up, adb reboot sideload, once the phone reboots and is prepped for sideload, adb sideload update.zip, and it did it's thing, now it's done, success, works perfect.

Just for safe measure, now that the phone is on 4ZUID, I did another factory reset, so the phone will remove every One UI 3.1 file that might be lingering in the background that could potentially be causing issues and so far I haven't had anything go wrong. Been working perfect all day. I signed into my Google account and Samsung Account, restored the backup, all apps so far are working. The only weird thing I noticed is that is now says my phone is SM-G998U1/DS instead of just SM-G998U1.

But other than that, I'm going to play the risky game and daily this thing just to see how terrible my life becomes if everything go south lol.

Hope something in this post helps people out.

EDIT:

eSIM also works fine for those who were asking.
[Samsung Galaxy S21 Ultra] readymarc:
Is there any lag? I also did a factory reset. Got alot less lag but pulling down notification shade and in app drawer was annoying so I went back to stable build. Saw a video where sstech was demonstrating the fluidity of the UI. His is really smooth, I even asked if it's beta 1 and he confirmed. Didn't ask if it was exynos or snapdragon. But mines wasn't as fluid as his. How is your experience?
[Samsung Galaxy S21 Ultra] bANONYMOUS:
It works flawless, at first I didn't even think it worked cause 4.0 looks so much like 3.1 that I thought the flash actually failed and it restored back to 3.1 until I checked the software info to see it was actually on 4.0

It's just like a normal phone, no lag at all, it's not getting hot or anything for daily use all day today. What apps are you running in the background? It might be something you have installed is not working well with 4.0 causing high background usage.
[Samsung Galaxy S21 Ultra] Slypnslyde:
Can you give me the exact instructions ti flash it using the alliance x app. I tried both renaming it to update.zip and just leaving it as a bin file anf both start to flash and then stop at 20-30% with the error message.
[Samsung Galaxy S21 Ultra] bANONYMOUS:
You need to change the firmware using the patched Odin 3.13.1

You have to be on the specific firmware FIRST before you can update to One UI 4.0.

So for instance, my phone is SM-G998W, if I flash the SM-G998U1 firmware linked in this thread, it will fail, I MUST be on SM-G998U1 FIRST before I can flash the update. So I need to use the patched Odin to go from W to U1, once I am on the U1 firmware with the latest update (4AUH9), then I can update to One UI 4.0

That is your first step, flash the correct firmware needed first using Odin, then you can update.
[Samsung Galaxy S21 Ultra] Slypnslyde:
So for instance since I'm on SM-G998U I have the Tmobile s21 ultra version of the the update. I need to flash that through Odin?
[Samsung Galaxy S21 Ultra] bANONYMOUS:
Only thing I can think of for this instance is the CSC causing issues, I was using XAA which is unlocked from samsung, no carrier specific version and it worked for me, so maybe try SM-G998U XAA? Instead of SM-G998U TMB like your phone has?

Or alternatively, try doing it the way I did by doing a factory reset and wipe everything, then set the phone up with no accounts and flash the update using ADB
[Samsung Galaxy S21 Ultra] death365:
OK so I've played around for a few days with the beta... its nice vut now I want to go back to stable.

How can I do that with out losing data?
[Samsung Galaxy S21 Ultra] bANONYMOUS:
I believe all you have to do is download the official firmware from Frija, flash with patched Odin, but make sure to use HOME_CSC and not CSC. CSC will wipe your phone, HOME_CSC retains data. And you should be good to go.

But, with all flashes, be prepared for a factory reset if something goes wrong, so backup your phone anyway just to be sure.
[Samsung Galaxy S21 Ultra] readymarc:
I think he should wipe data. Problems might occur with moving from beta to stable. I did that just in case of any app data problems that might present itself.
[Samsung Galaxy S21 Ultra] readymarc:
You're lucky, I did a fresh install and installed apps one by one, no restore and still it lags, well not much but navigating the app drawer left to right, you can notice the drop frames.

You have the snapdragon or exynos?
[Samsung Galaxy S21 Ultra] Juice3250:
I'm probably going to skip the Beta until it gets another update. I hate wiping my phone. I need all my apps to work. I rely on it too much to take a chance, as tempted as I am.
[Samsung Galaxy S21 Ultra] Swagdog234:
Have we gotten the S21+ snapdragon one ui 4 beta yet? It's not linked
[Samsung Galaxy S21 Ultra] DS1000RR:
I get app drawer lag but only when running Amazon Prime or Netflix at the same time. I'm on Exynos. Pretty stable for a beta 1. Everything else functions well.
[Samsung Galaxy S21 Ultra] bANONYMOUS:
What bugs are people getting? So far everything except for the DJI Mimo app works for me, it just force closes when I try to open it, and randomly after about a day of use, the swipe up to go home gesture doesn't work until I restart. But restarting my phone every morning, I haven't seen this issue again.

So realistically, the only issue's I'm having is that one app doesn't open, and I have to reboot my phone every morning so the swipe to home gesture remains working, it's really not the end of the world and this is insanely stable for a "beta"

I'm also not experiencing any slow down or lag at all with the app drawer or notifications, but I'm also using Nova Launcher so could possibly be a One UI launcher issue cause I don't have any lag at all with Nova. I also have the phone set to 720p, with the DPI changed to 512 which gives the same scaling at the 1440p resolution, while using basically half the power for the display which might also be a cause of not having any lag.

What kind of issues is everyone else getting?
[Samsung Galaxy S21 Ultra] maddoggin:
so does your phone have to be on certain update to receive this? i tried to sideload and update failed because build date on my phone. i have the august security patch G998uSQS4AUI1
[Samsung Galaxy S21 Ultra] maddoggin:
sorry ihave sept security patch G998USQS4AUI1
[Samsung Galaxy S21 Ultra] bANONYMOUS:
You can update from that one too, it just cant be older than 4AUH9
[Samsung Galaxy S21 Ultra] Wacky2bakky:
Beta 2 will be coming sometime next week for the Galaxy S21s
[Samsung Galaxy S21 Ultra] maddoggin:
I'm guessing you have to reset your phone and before running thru setup reboot to recovery and flash update? But then how do you get adb permissions after reset? You'd have to run thru real fast and go to setti G's give adb permission and flash updates but that defeats the purpose doesn't it? Sorry just trying to figure out why I keep getti g error whe. Sideloading update.
[Samsung Galaxy S21 Ultra] elliwigy:
i left detailed instructions and explanation as to why in a previous post specifically for G998U and G998U1 devices lol..

There is no g998u xaa firmware.. xaa is samsung usa unlocked model which is the U1 models i.e. g998u1=xaa g998u=tmb,spr,att,vzw etc. etc. But yes, if they are using a g998u1 4AUH9 to 4ZUID update.zip then they need to use modified odin and flash g998u1 4AUH9 firmware to their g998u device then adb sideload the update zip
[Samsung Galaxy S21 Ultra] elliwigy:
you dont need adb permissions to adb sideload.. use physical buttons to boot into recovery mode then select apply update using adb and it will load into sideload mode and display on the screen adb sideload filename.zip when its ready
[Samsung Galaxy S21 Ultra] elliwigy:
not accurate.. it has to be on 4AUH9.. depending on the zip hes using.. i posted few pages back how to check what you need to be on and suggested ppl linking zips add yo their post what firmwsre is needed to start to avoid these issues but its not my thread soo..

long story short, all ota updates have an update script so it will check the firmware on the device to make sure its a specific firmware and also not modified in any way before it will flash..

if he is using say G998U1 4AUH9 to 4ZUID update zip then he needs to first flash to G998U1 4AUH9 firmware before installing the update zip.. if his update zip is G998U 4AUI1 to 4ZUID then it should work.. i assume tho bcuz hes getting errors hes not on the right base firmware for the update zip hes trying to use..

updates have always been this way
[Samsung Galaxy S21 Ultra] Dstu10:
Is there anyway to downgrade from the September security patch and push the beta? I'm currently on 998u with a build number of UI1.
[Samsung Galaxy S21 Ultra] maddoggin:
Thank you!
[Samsung Galaxy S21 Ultra] maddoggin:
does anyone have update from AUI1 to beta UI4
[Samsung Galaxy S21 Ultra] pspbyer:
Have you tried the sideload with alliance x app?
[Samsung Galaxy S21 Ultra] bANONYMOUS:
Correct, gotta be on XAA 4AUG9 U1, wipe everything, set it up with no accounts or anything, enable usb debugging, use adb to sideload, side load update, reboot phone, factory reset again, then set it up like new and for me everything is working fine.

Alternatively you can power off the phone, then hold volume up and power until it says Samsung, this will go into recovery mode. You can then use the volume buttons to navigate up and down to Apply update via ADB and hit the power button to prep adb sideload instead of setting up the whole phone like elliwigy mentioned.
[Samsung Galaxy S21 Ultra] bANONYMOUS:
You should be able to still sideload the update.zip as long as you're on SM-G998U1 XAA AUH9, you just gotta downgrade using patched odin

I have a full guide with all links to the files needed for SM-G998W/U/U1

One UI 4.0 Beta Flashing Guide

How to install One UI 4.0 Beta for Samsung Galaxy S21 Ultra SM-G998W, SM-G998U, and SM-G998U1 This will also work for S20, S20+, S20U, S21, S21+ and all Exynos variants You will need to find your own firmware files for those specific devices. Credit to elliwigy and realbbb for contributions Gu...

[Samsung Galaxy S21 Ultra] maddoggin:
I have G998U TMB Galaxy s21 ultra software version G998USQS4AUI1
[Samsung Galaxy S21 Ultra] Dstu10:
I believe you would need to downgrade to the 998U1 XAA AUH9 software version and then load the update.zip. The only other way would be find someone that has the AUI1 update.zip, which to my knowledge doesn't exist as the beta was released before the September security patch. You could try and find the 998U AUH9 update.zip but I doubt it would work.
[Samsung Galaxy S21 Ultra] MastNi:
I am part of this activity it's my pleasure
[Samsung Galaxy S21 Ultra] Dstu10:
I would also say, it might be worth waiting a week as the new beta is rumored to be released in about a week. I can honestly say, there isnt much of a reason to go through the work of a full reset to get on one ui4.
[Samsung Galaxy S21 Ultra] dolganov:
How did you make EFS backup?
[Samsung Galaxy S21 Ultra] elliwigy:
yes.. flash the 4auh9 firmware
[Samsung Galaxy S21 Ultra] maddoggin:
I am also in the same boat, the people in this thread have been very helpful in explaining the options. Basically we have to downgrade to older build or wait till beta 2 (which will probably be this coming week) and then see if builds improve for us to flash other wise in order to flash beta we must downgrade. I'm choosing g to wait a few more days and see if my chances improve. Someone posted a write up o. How to downgrade if you choose other wise! Good luck
[Samsung Galaxy S21 Ultra] maddoggin:
so i decided to go ahead and try out your right up. it seemed pretty simple. i did everything as directed and it failed after hitting start on odin . i git fail SHA256 is invalid
[Samsung Galaxy S21 Ultra] maddoggin:
do i need to do a factory reset before going into download mode and hitting start on odin?
[Samsung Galaxy S21 Ultra] maddoggin:
oops my bad, lol had the wrong odin ,looks like everything installed good just installed one ui 4 and will skip through and factory reset then come back and let everyone know how it went. so far so good
[Samsung Galaxy S21 Ultra] maddoggin:
well , except for my phone changing from model G998U to model G998U1/DS ( what does that mean ) everything seems ok. how can i get it back to G998U

update: so i wasnt happy having my phone as G998U1/DS soi went back and i found a one ui beta4 update zip from 4AUGQ to 4ZUID and reflashed my phone back to 4AUGQ-TMB and then flashed the update.zip which is what i shouldve done from the begginning everything good now
[Samsung Galaxy S21 Ultra] bANONYMOUS:
Awesome, glad you got it sorted out.

I just spent the last few hours cleaning up the guide, updated with easier instructions and junk for accessing ADB Sideload and factory reset without setting the phone up first after the initial flash of One UI 4.0

I also have no idea why it adds the /DS for this new version. But one thing to mention is that if you're coming from a W phone, Bixby Alarm will only read the weather out in Fahrenheit, there is no way to change this, and Samsung Pay will only let you enter a ZIP Code but I found a fix.

I have it all in the "// NOTES" section of the guide.

But I can confirm that I'm using a W phone, and a Canadian Visa with Samsung Pay on the beta U1/DS and it works fine. Quick access from the lock screen, tappy tappy for my coffee, back at my computer for another few hours to yell at technology until my mental sanity eventually diminishes.
[Samsung Galaxy S21 Ultra] JG96EVO:
Sounds like you didn't use the patched Odin if it failed.
[Samsung Galaxy S21 Ultra] maddoggin:
What does the DS stand for? I'm back to G998U but it still has DS I don't use Google pay or samsung pay so no problem there phone still seems the same no real changes. Also I don't use Bixby either. I use adb to remove a bunch of those apps. Also noticed after start it opens a Sim screen, is that new in 4.0 or does that have something to do with DS?

I'm a regular user of X8 Sandbox VM on my Galaxy S21 Ultra.

Today I installed Samsung's new UI 4.0 Beta that runs on Android 12.

I didn't think for a second it could screw up my X8 Sandbox, which now loads and loads, but nothing happens.

Anyone have any idea on how to solve this? Uninstalling and reinstalling X8 didn't help, obviously.

[General Questions and Answers] ChainSword20000:
I have looked into rooting, and I don't understand how it works, but from what I can tell, shouldn't people be able to root using adb to change a file that is run regularly in /system, so that whenever it runs it would grant a given app root perms, and that app would then be able to give others root perms? would you have to change the file another way because adb doesn't run commands as root? wouldn't this be alot more simple than what has been being done?
[General Questions and Answers] :
Rooting a phone''s Android technically is simply adding standard Linux function SU ( read: Switch User ) to Android's ecosystem.

Once SU got added and you run the file without any other parameters it switches your credentials and permissions from a normal user to that of the superuser ( comparable to Administrator on Windows OS ). You are then in complete control and can add anything, remove anything and access functions on your phone that you couldn't reach before.

BTW:

With Android versions 6 and higher all what is needed is to replace the pre-installed ( restricted ) Toybox binary with an unrestricted Toybox binary ( e.g. 0.8.5 ) that contains the SU-cmdlet.
[General Questions and Answers] ChainSword20000:
If I am understanding this, than you need to grant an app SU, but first you have to install the command that allowes giving of SU? or turn on that command (on android 6+), and grant a manager app permission to use it?
