How to update kernel on Wd EX2 Ultra? (Debian uImage and uRamdisk flashed) (1 reply)

Hi all, i had modded my Western Digital device with the following guide some time ago:

https://wd.hides.su/wdnas.el8.website/WDMyCloud-Ex2-Ultra/Debian-linux_4.14.4/_info_EN.txt

This is using an old kernel 4.15.0-rc6 and i would like to update it

Any tips or suggestions???
Since the kernel is on the device itself and not the hdd, updating it via shell does not work (i can update it but there is no GRUB to point to the updated kernel), so i think i heed to find a new updated uImage and uRamdisk for it?

Thano you all in advance
