today I tried to update my MXQ pro 4k from version 8.0.2b (I think) to version 8.1.9.
My first try with SD-card failed. I used LibreELEC-S905.arm-8.2-8.1.9.img.gz and the dtb-file for MXQ pro 4k.
The MXQ freezes while displaying the boxes start-logo.
Then I tried to update via SSH with the same image.
Now the box freezes also at the start logo. Nor libreelec neither Kodi is loaded.
I think the LibreELEC-S905.arm-8.2-8.1.9.img.gz file is not working on the MXQ pro 4k.
Where can I find an older Version to repair my box?
