I just got OneUI 4 Beta 1 working on my XSA S21 Ultra (Exynos).

1) I had to update to the latest Android 11 firmware - AUHD.

I used Frija to download an Indian AUHD Rom - flashed it using ODIN - used Home CSC to keep my data.

2) Updates from AUHD to OneUI 4 Beta 1 ZUIC using the ADB Update.zip method.

Hope this helps!

Thank you so much. Does your cell service work well still?

The OP has a Snapdragon SoC, your solution can't be applied to a Snapdragon variant.

    5g and calls over LTE works well. I am using Telstra (Physical sim). I dont use esim. but I assume esims will not be an issue as "Service Provider Software version" still says XSA.
