Unable to boot/install despite correct dtb


I have an old S912 (8 core, 3GB RAM) running Kszaq’s old Libreelec 8, I want to upgrade that to CoreElec.

Libreelec at this point runs well, despite being old. cat /proc/device-tree/le-dt-id says:

So I downloaded the generic arm CoreElec, burned it to a stick, then mounted it and copied over the following file as dtb.img in / (copied it also to /device_trees):

I unmounted the stick and inserted it in the S912 box, however it will not boot, it’s just stuck at the S912 logo (attached). Any ideas?

Why you using a different dtb? You need to use the included one in the device_tree folder.

Because the old libreelec tells me I need gxm_q200_3g and I can’t find this in the device tree on CE…

If I leave the generic image untouched, without adding the gxm_q200_3g it still gets stuck at the S912 logo …

Wrong forum then, here is CoreELEC.
Try all other dtbs.

Unfortunately none of them produced a successful boot…

You have to download CE 9.2.8 stable, burn it and copy gxm_q200_3g.dtb from device-tree folder.
I did it on my very old Vorke Z6 device - it works.

Don´t burn CE 19.3 !

Thanks @Tim_Taylor

Burned that to a microsd card, but the gxm_q200_3g.dtb file was not in the device tree folder. I copied it from my old LibreElec but it will not produce a successful boot, it just gets stuck at the S912 logo.
Can you by any chance share your gxm_q200_3g.dtb?


A little bit wrong link from Tim_Taylor, should be non-ng version for S912 boxes. There you could find correct dtb file.


And don’t copy dtb file from other distribs

Sorry, corrected the link.
The gxm_q200_3g.dtb file is in the folder device-trees.
Another way to get the gxm_q200_3g.dtb is downloading the .tar file (CoreELEC-Amlogic.arm-9.2.8.tar) and extract it.

Thanks @boot2k3 and @Tim_Taylor , it works! :slight_smile:

Quick question, with this version of CoreELEC on this old S912 can I expect 4K/60FPS/HDR? Originally these features were listed in the specs, but the original OS was some dodgy Android.
