Which DTB did you use when trying to boot?

Did you follow install instructions correctly and rename the file to dtb.img and move it to the root of your sd/usb?

5

After use tool LibreeELEC …
i copy file dtb from folder tree to root sd and rename it to “dtb.img”

Have you tried the other dtb’s?

Please provide a copy of the original DTB from your device, this can be obtained in Android using dd if=/dev/dtb > /sdcard/dtb.img.
