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.

So guys after rebooting to Recovery. Using the powershell to flash the zip that's what I got. "Cannot read update Zip"

When I change update .zip to zip it came up as "Update" on the PC. I'm lost guys. What am I doing wrong? besides I'm used to update beta using sdcard but since we can't use sdcard on our device I don't know what to do. Kindly help out. Thanks

You put that update.zip file inside platform-tools folder, and that should do it, don't worry about it not showing extension in name, from picture it definitely is zip file.

@x10forevers or anyone else, what do you think for the Beta ? Any comments or issues ?
It's working great as far as my usage is concerned, battery did drained fast first couple of days but after that battery seems to be holding better than before, for me at least and I think having to do fresh install also helped with battery life instead of dirty flash.
I love the animation on Samsung keyboard, and getting material you design in - at least google apps.
And some of the new features that everybody has mentioned that they implemented in this.
Overall happy with it, considering it is beta version, some glitches are to be expected.

Do you by accident using The TD bank program and the Samsung Pay ? If you are using then do they work ? Are all the programs that you have them from the Google play working ?

Are the good lock programs working?

All of my account is linked to Google pay, because my ticwatch has google pay on it , and everything is working on Google pay as before for me. I am with Scotia and tangerine , all of them work on Google pay .
May be someone who is using Samsung pay can confirm this.

My hand is very itchy and I think that I will try it . I backup all my data with Samsung Switch and I have downloaded all the necessary programs and files.

I guess that if I don't like it I can revert back to G998w

I also have the zip on my desktop should I delete from the desktop and leave it only inside the Platform tools folder?

    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.
    and just to make sure that you're not an idiot, this is for SAMSUNG phones only and only for S21 Series. YOU CAN TRY THIS METHOD ON OTHER SAMSUNG DEVICE BUT YOU WILL NEED UPDATE FILE OF ONE UI BETA 4 FOR THE DEVICE YOU TRYING TO FLASH


    -- 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.​

    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.

    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.
