RK3528 HLink-H28K flash to EMMC!!

[fari2000]

I managed to make Lemfo hk1rbox k8s to run with the release HLink-H28K using
PRETTY_NAME="Armbian 25.2.1 noble"
NAME="Ubuntu"
VERSION_ID="24.04"
VERSION="24.04 LTS (Noble Numbat)"
VERSION_CODENAME=noble

and an extracted dtb from android.
Is there any reliable instructions on how to flash this release on the EMMC of the Lemfo hk1rbox k8s?

Thanks for your reply

dd if=armbian.img of=/dev/mmcblk1 bs=1M status=progress

Thanks alot for your advice.
I saw some instructions advising first to copy the /dev/mmcblk1 as below
dd if=/dev/mmcblk1 of=/boot/u-boot-default-aml.img bs=1M count=4

and than restore it with
dd if=/boot/u-boot-default-aml.img of=/dev/mmcblk1 conv=fsync bs=1 count=442
dd if=/boot/u-boot-default-aml.img of=/dev/mmcblk1 conv=fsync bs=512 skip=1 seek=1
Is that wrong?

I have followed your advice, that bricked the TV box:
I have done
dd if=armbian.img of=/dev/mmcblk2 bs=1M status=progress (/dev/mmcblk2 is the EMMC of the TV BOX)
Than I mounted the boot partition, I modified the armbianEnv.txt with the right name dtb, than I did reboot--> TV BOX is dead
It does not boot from emmc neither from SD card.
What was wrong?

Just use the h28k firmware without modification
