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.

Your reply makes no sense too. GKI kernels are generic kernel but no focus on particular phone. So if the X15U heats more, a less agressive kernel with CPU/GPU could be fine, it is the meaning of my question. The latest working kernel is version NEXT-12823 is dev not a stable released. And i have this one installed.

Ok, gents
After spending an evening, I was finally able: to install KernerSU-Next, to found its status "Working", to install Horizon Kernel Flasher, to flash Androir3....img, to add the SUSFS module into the KernelSU.
So, I assume that I have done everything to have the xiaomi.eu ROM on the Ultra15 and to have a hidden SU from apps. Why though I have the problem on setting the GWallet to work with my card - it says "Your phone is not secured" blah-blah-blah...?
Disappointed

Because hiding root and passing Play Intigrity have nothing to do with each other. You can have completely hidden root like you will now and not even having the basic check in play intigrity. For the wallet to work, you need the maximum play intigrity level (strong). You need a valid keybox. Look for info about what I'm telling you on Telegram, XDA, Google...
