Powershell is what you'll get if you have Windows 10 pro

When you're in recovery and have selected update via adb, enter these commands one after the other including "./"

. /adb devices
. /adb sideload update.zip

Should work

First of all, as you all know - you are responsible for anything that you do to your device, neither me nor anyone helping you are responsible for it. Of course this generous community will help you through if anything unexpected happens.

-- The process I am explaining and/or describing here is tested by me and it works 100%. I have Canadian S21ultra which is not part of the beta program, I tried to install beta update on Canadian firmware but it failed so I tried this method and I have successfully installed ONE UI 4 Beta and everything works. This should work with S21/S21+


This is a few steps process so read carefully through each and every step, I am gonna try to keep this as easy and noob friendly as possible, if you have any questions feel free to ask.

-- This process will take place in 4 parts so it doesn't get confusing, it needs to go in chronological order.

Step 1 : Download needed files and tools for your device
Step 2 : Backup your data
Step 3 : Flash current stable firmware for your device family either exynos or snapdragon via ODIN
Step 4 : Install One UI 4 Beta 1


Step 1 : Download needed files and tools
1. ODIN tool to flash the firmware (Search xda/Google for this)​
2. SDK Platform-tools from here SDK Platform-tools - once downloaded, extract files​
3. CURRENT stock firmware of the device (One UI 3.1) - This is the latest One UI 3.1 firmware from the country getting beta updates.
- For Example : If you are installing UK One UI beta, Download Latest Stable One UI 3.1 firmware from UK which is compatible for your device (Please make sure it is the same processer as your current device, if you have exynos S21 device, download exynos and if you have snapdragon version download snapdragon one) -- you can download it from Galaxy Firmware Website or website or source of your choice.
- Extract Firmware zip.
4. Beta Update zip file - Copy this file in Platform-tools folder and rename it to update.zip if needed.​
Snapdragon Version : Click Here
Exynos Version : Click Here
Step 2 : Backup your data (Recommended but not necessary)
1. Samsung smart switch for Computer -- From Here
2. Samsung Cloud Backup - from settings of your device.​
3. Google Backup - from settings of your device.​
Step 3 : Flash Current stable firmware corresponding of your device family either exynos or snapdragon via ODIN - This step will wipe all the data on your phone.
1. Open ODIN executable file (i.e. exe)​
2. Connect your phone in download mode to the computer via USB cable (Turn off your phone, while pressing volume up+down button, plug in the USB Cable to your computer, you will see teal screen with some disclaimers on your phone, press volume up)​
3. Click on BL on ODIN screen and navigate to the folder where you extracted firmware from step 1, click on file name starting with BL_xxx.tar.md5, wait for it to populate in ODIN. Repeat process with AP, CP and CSC (NOT HOME_CSC) in ODIN (AP will take a lot of time to load so grab a coffee/bear/Tea or whatever you like while that processes).
4. Click start and wait for that to be finished​
5. You will see success in ODIN and your device will reboot to the system​
6. Turn off your device by pressing power button once its booted.​
Step 4 : Install One UI Beta 1 update
1. Boot your phone into recovery by continue pressing power and volume up button, once you see the samsung logo release both buttons.​
2. Select Install update from adb​
3. Open platform-tools on your Computer, hold shift and right click - select open command prompt here.​
4. write adb sideload update.zip​
5. Wait till the process finished.​
6. Power On your phone by pressing power buttons and your device should boot into One UI 4 Beta.​
7. Follow on-screen instruction to set-up your phone.​
Just to point out that if you are Flashing the US Betas on a Canadian device, you have to use Patched Odin to Flash or the Flash will fail.

That title is so wrong, not sure why admins haven't called this developer to order, says "... any device (Exynos+Snapdragon)" and yet this is not compatible with all these devices but just the S21-series, what a click bait this is.
First - It's in the s21 ultra forum, not in general forum, so it's given that it's for s21 device and not all devices.
Secondly - Read the OP and you will know that it's not for all devices and
Third and lastly- scientist have said that it helps if you use your brain once in a while and apply common knowledge.

One UI is only for Samsung and it's in s21 forum plus you can't use Odin with other device but only Samsung so that's just idiot proof.
Hi
Please can i use this method for Galaxy M51 ?
Thanks
Won't work unless you have beta update file of M51.
MIght try this on Note 9
Won't work unless you have file for your device.
hey .... but your title is wrong ... it's only for the S series .. ???? ...
It's in s21 forum, so that's given that it's for any s21.

I click on the download links for Beta One UI 4 update.zip files and they only work when I open in incognito tab and they download a .bin file. Is that correct?

Yes it is a bin file, you have rename that file to update and either you can change extension to zip or leave as bin either one would work but if you keep extension .bin, you have command adb sideload update.bin instead of and sideload update.zip

Hmm, interesting. Everything seemed to work fine. Command prompt finished with "Total xfer: 1.00x" but when I boot into OS it is still on One UI 3.1. Tried Software update and that did not pull anything new. I will try again.

My device is Canadian SM-G998W running One UI 3.1 with August Security patch. I downloaded the official firmware 3.1 for my device and the Snapdragon Beta UI 4 for T-Mobile G998U.

Maybe I will try again and change the Beta UI file to .zip.

You'll need to flash firmware with September security patch , if your current firmware is of August firmware it will not flash one UI 4.

    This is the list I see when I go to the Official Firmware site:

    View attachment 5419435

    The latest I see to flash is August 24th. Does this mean that the September Security patch is not available yet? Sorry, I am fairly new at this.
    You can flash US XAC firmware, search for G998U1 device. I did the same, as Canadian version doesn't have september security update yet. Or wait til your device gets security update. It should be in next couple of days anyways.

    i just cry when i read people having those amazing SOT on their phones, and i 've never pased beyond 4.5 hours, maybe scratching the 5 hour mark. Usually im having between 3.5 and 4 Hours.. i charge my phoine twice a day sometimes 3 times.

    hello. I have the unlocked version (g998U1). Looking for the galaxy firmware I can't find the carrier free version. The firmware version corresponds to mine but there is only carrier versions. do yo happen to know if any of this version works with mine?
    I'm scared of having verizon bloatware in my unlocked device lol
    Go to galaxy firmware website on OP and select XAA version from there, that's the carrier free version. Regardless any firmware should work as your device is not carrier locked.

    Just an update, this worked however flashing just the bin did not work, and I needed to use the update ZIP which I found at this link (For Snapdragon model and only the U1 version):

    And now which firmware you suggest I should download to install on my Hong-Kong G9980 S21 ultra snapdragon first to accept sideloadin the beta?
    Guessing it's a snapdragon processor, latest US 3.1 firmware (G998U1) one would be your best bet.
