How to do root (Magisk) on Xiaomi 15 when not using TWRP? Thanks

unlock ur phone..
and patch boot.img or initboot.img with ksu or apatch aplication

Init_boot.img in this case, extract from your own ROM and patch, then flash in fastboot

I can confirm that init_boot.img works. I was using this guide and was able to find out as well: https://topjohnwu.github.io/Magisk/install.html

SFollow the guide for the root app you want to use. This has nothing to do with Xiaomi.eu.

Kernelsu + susfs is the best on the Xiaomi 15. Having the GKI kernel allows you to completely hide everything. But it is more complex to install than Magisk. If you don't even know how to install Magisk without TWRP, it is complicated.

Can you send me please a Manual or link to kau+sufs ? Thanks

Kernelsu + susfs je nejlepší na Xiaomi 15. Mít jádro GKI vám umožní úplně skrýt všechno. Instalace je ale složitější než Magisk. Pokud ani nevíte, jak nainstalovat Magisk bez TWRP, je to složité.

What kernel are you using for the Xiaomi 15? I want to run GKI but after flashing the kernel I get stuck in fastboot.

I would do it myself if I had gsk kernel 15 ultra

What kernel are you using for the Xiaomi 15? I want to run GKI but after flashing the kernel I get stuck in fastboot.

Wild+ version 6.6.66, Any version 6.6.x works... that's how GKI works. If your Xiaomi 15 Ultra has the stock kernel 6.6.x, you can use any version that has that version. The x doesn't matter.

If I give the command fastboot boot, the system boots up and shows GKI, but if I want to write the kernel with the command fastboot flash boot, it only boots into fastboot. What am I doing wrong? But I have a xiaomi 15 not an ultra

Have you followed the steps for GKI? Wild plus own GitHub provides a link to the instructions. Read the GKI mode installation.

 

[r.dave]

I'll do everything right. I don't know.

So basically after some testing, here's what the step that work for me, could work for you too

1. boot the image using

fastboot boot boot.img

(in this case i use android15-6.6.77-2025-03-boot.img)
2. download the horizon flasher then grant root
3. flash anykernel (in my case it's android15-6.6.77-2025-03-AnyKernel3.zip), in the horizon flasher
4. let it reboot
5. profit

 

[r.dave]

Thank you friend, I tried this method with some older kernel version, but horizon kernel flasher didn't want to install, it said it only had lkm root. Now everything went exactly according to your instructions.

 

[gorillalaci]

Anywhere Here and try ROOT with KSU ....patch the init.voot.img and after that flash with Fastboot?

 

[r.dave]

This procedure did not work for me. Follow the Xonline instructions. This works.

Why ? What goes wrong?

 

[r.dave]

The system will not boot, but will enter back into fastboot.

 

[gorillalaci]

What steps you have make it ?

 

[r.dave]

Same procedure as on the kernels website. I downloaded the kernel and flashed it with the fastboot flash boot command.

But you have Patched the init.boot.img with KSU before and flash the Patched IMG ?

That's right, now you just need to play Intigrity and nothing will detect you.
