Hi, sorry if that topic was discussed already (I was not able to find any clear solution).
I purchased Mi 11 Ultra that has 12.6 21.8.18 beta version and Android 11.
I wanted to update the MIUI using OTA with 12.6.21.11.11 but I got info that there are no links / mirrors available and I was not able to download the update.
I found the rom in official Sourceforge and downloaded it. I tried to install via TWRP, but it.failed...
I saw something about installation via Fastboot - but I guess i need to unlock bootloader = lose warranty.

Do you have any idea how should it be done?
Can I have updates and still have warranty (and do not root it)?

Thanks

Not need unlock bootloader, the phone chooses the link itself.
Go to Settings- My device-MIUI version-Check updates

You have TWRP? your bootloader is unlocked.
This is not the point. If you want to update to latest EU you have to use fastboot install.
have a search, many explanation on the main topic.
