Homatics Box R 4K Plus

Hi to all, i’am an old xbmc user since xbox one and it’s variant (openelec, libreelec)

First time with coreelec

So i haver a 4k plus with atv 14 4576

I followed this guide

And installed this file:

CoreELEC-Amlogic-ne.aarch64-21.3-Omega_nightly_20251102-Generic.img.gz

Tried a reboot with jamal reboot to coreelec but i only see a bootloop of homatics logo (tried first first reboot and after normal reboot)

Tried adb reboot update but even if i’m connected with adb tools i get adb devices /system/bin/sh inaccessibile or not found

Will try later with a pc

Btw where i’m wrong ? why i get bootloop instead of coreelec? thx
