Step by step of how I unlocked, installed xiaomi.eu and rooted my phone Xiaomi Ultra 15 XUANYUAN global bought in Sweden, 2025-03-15


Sorry you are right. I would just say NEXT-12807-android15-6.6.77-2025-03-AnyKernel3.zip is working not NEXT-12701-android15-6.6.77-2025-03-AnyKernel3.zip.
But all the versions above 77 (6.6.82 etc...) don't work.
Can we find a specific kernel for the Xiaomi 15 Ultra ? Anykernel seems to be generic, isn't it ?
 
Download android15-6.6.*-boot.img from WildPlusKernel to your computer.
There are no files with that name. All files end with .zip or .gz.

I don't think you understand what GKI is. You should read up on Google; there's tons of documentation about it. All Android phones from Android 12-13 onwards must have GKI. Your GKI kernel is exactly the same as that of a Samsung, Pixel, Oneplus... Your question makes no sense
 
Read the entire thread in this post. Always download the gz .zip and flash it with Horizon Kernel Flasher. The latest working kernel is version NEXT-12823-android15-6.6.77-2025-03-AnyKernel3-gz.zip The kernels will be updated on GitHub, so always download the latest stable version. Skip the unstable versions, which are based on kernelsu next dev development.
