Samsung Galaxy S21 Ultra
The beta version on G9910 no problem. On Odin I flash as indicate the BL, AP, CSC, for the CP (Modem) I replace it with that of BRI (Taiwan) of the same security date.
Installation of the beta file with ADB without problems.
I deleted all unnecessary Chinese apps. I cannot say if 5g works because my plan does not include it but 4g no problem in France. I don't encounter any particular problem only a few system applications still in Chinese, like bixby.

Thanks to zjhao for sharing the beta links
Did u use Home csc ?
 
Still on beta 2?

Any feedbacks about your experience ?
Yeah I could only find the beta here through zjhao's drive so unless he decides to upload more I'm stuck with this till the official release. But overall not bad except few bugs like Material You color theming stuff doesn't work at all, there's an occasional SystemUI crash and interestingly location sharing on WhatsApp is a nightmare I don't know how this could be messed up but there you go also you can't backup Samsung Health data unless you're from China. There are also some Chinese lettering which appears on call screens sometimes on a couple of my contacts. But aside from these problems the new widget animations are really nice and the overall it's snappier than One UI 3 but every now and then it stutters but for a very short time. The battery life is similiar to One UI 3. I will keep using it as none of the problems I said affect my daily usage that much.

    I still think Samsung is holding in the update because of some issues that was countered in the Exynos and the US Snapdragon variants, they will for sure release the SW when they get approval from all operators involved even though if your unit is unlocked but still they push the update for all at once.

    Reading in Reddit about all the bugs in UI4 it may be an advantage that we are last. Perhaps some more bugs will get ironed out..

    Hello!

    I've posted a detailed guide on installing (sideloading) One UI 4.0 on unsupported countries manually. I've linked the update.zip file from this thread. You can check it out here.
    I've seen your great job, but our version of the S21 ULTRA is only beta 2 and no news concerning beta 3 or 4

    how did you install the beta version ?
    First you download AUI6 firmware with CHC region csc (I downloaded from SamMobile but anythings ok as long as the csc and the build numbers are the right ones) and flash it with odin and head to https://cherrydrive.cn/s/l4jiJ?&continueFlag=8996eae0c64321f7eee9c45aadff3f8c&path=/
    password : beta
    and download the beta and flash it using adb sideload
    and also you can thank zjhao earlier in the thread for the uploads.
