Android 12 and One UI 4.0 Beta OTA files of G9910/G9960/G9980 have been extracted, shared and uploaded by Chinese users. I can provide a link if necessary, but the cloud space seems to be in Chinese
Need to flash into the Chinese version of the firmware (CHC)

From what I've seen on the forums it's now easier to change the CSC so if you share the link I would be willing to give it a go mine is the Taiwanese version btw (TGY)
Edit: And also if you could specify the build number which you updated from the latest seems to be AUI6 but I just wanted to make sure as sammobile downloads are slow af

I think there's no need for chc firmware, the firmware is the same, only the version is necessary to install on it.

    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.
