You need to use the correct DTB with CoreELEC.
If you upgraded from an old LE version, put the SD card in your PC and copy + rename the correct DTB file from the ‘device_trees’ folder.

I have Mecool KII Pro.
I copied gxbb_p200_k2_pro.dtb from the “device_trees” to the root directory and renamed it to dtb.img

#4

Definitely a DTB issue.

Are you sure your not running from internal as the DTB update procedure is a little different then.

#5

There are two version of KII pro with S905 and new one with S905D. For S905D use gxl_p231_2g_dvb.dts.

For new Ki Plus with S905D use gxl_p231_1g_dvb.dts.

No I’m not running it from internal storage. I have android on internal.

I solved my tvheadend server problem by importing tvheadend configs to a fresh CoreELEC installation.
