Unable to change OS on VIM3

Thanks for the response, I did actually attempt to flash that HAOS image to the emmc, but the burn tool seems to think that it’s an SD image:

utils/burn-tool -v aml -b VIM3 -i OS/haos_khadas-vim3-10.4.img
Try to burn Amlogic image...
ERROR: Try to burn to eMMC storage, but the image installation type is 'SD-USB', please use 'EMMC' image!

So I assume you mean you installed to SD and copied to emmc?

The problem I’m having is that none of the tools are working as expected, USB_Burn_Tool refuses to load any image, giving Parse burning image fail error for all images. This is even after a reinstall, and whether the VIM is connected or not.

Similarly, the Ubuntu version stops short of touching the emmc (not even wiping it): Unpacking image [KO]

The final issue is that the maskrom mode will not work with the AndroidTV install that’s on the emmc, since it seems to be overriding the boot somehow. The triple press method does something, causing a boot loop with a garbled screen. If I try it with krescue I can see a yellowified khadas logo in the “noise” just like the image in this post, only it’s mixed in with the android boot image.

So in short:

  • I can’t boot from SD card, because of the ATV install on the eMMC
  • I can’t wipe the eMMC because none of the burning tools will work

I’m assuming that if I can either force boot to SD somehow, or wipe the eMMC, the other problem should fix itself. I’m fairly sure it’s not a hardware issue.

Hopefully I’m just doing something stupid!
