I'll never be able to say it, but this community is the best I've ever seen.
I want to thank you because once again, I couldn't have solved the problem without it.
Thanks @djurny, all the people of this post.

Hi all,
Today I upgraded armbian on my Helios 4. I wish I hadn't. The system won't boot anymore. Received the "Wrong Ramdisk Image Format Ramdisk image is corrupt or invalid" message.
Any hints on trying to recover from this? To be honest, I'm stuck at the moment.
I recovered from this through the following steps:
Get the 'original' image (although dated) from the Helios site (https://wiki.kobol.io/helios4/) Created another sd card Booted And had access again. The hardest part was recoving the old lukskey for opening the encrypted partitions from the raid array. -

This is the command to flash the bootloader onto the SD card: https://wiki.kobol.io/helios4/uboot/#on-development-pc
As you can tell, it's basically offset by 1 on the SD card.
kernel 6.6.79 boots now.

@Mangix
Thank you, that was simple.
@Dee2022
What I did:
Download of the 1st SolidRun image (... sd.kwb) Copy the image to SDcard containing unbootable Armbian 25.2 (on my Linux desktop using dd, SDcard available here at /dev/sdf) sudo dd if=u-boot-helios-4-sd.kwb of=/dev/sdf bs=512 seek=1 status=noxfer sudo sync Boot Helios4. Voilà.
