Device-trees from 3.14 kernel images are not compatible with the 5.1 kernel .. so the lack of boot is not surprising. PEBKAC.
I apologize for this simple mistake and thank you for the answer...
I flashed with "LibreELEC-S905.arm-9.0.2" on my Mecool M8S Pro W
dtb used: gxl_p212_2g.dtb (inside the "device_trees" folder)
- Wired network looks connected and work !
- Wireless network active but does not work !
- Notice that sometimes there is a sound problem, I changed the hdmi input on my tv sound is improved and no problem.!
* After trying long hours: For my device "LibreELEC-S905.arm-9.0.2" was heavy, slows down when using and when I check the temperature works hotter than the old version. I'm back to the "LibreELEC-S905.arm-8.2.5-Chroma.422.10bit". It's faster, less warming and more responsive for my Mecool M8S Pro W right now.
Best Regards,
