Thank you for you replay. 

I have installed the image file and the FW LM5M4 20211014 and recovery-mxs-1g.img.gz to the SD-card with USBIT. 

But when I put it into the LM5 and power it up, there is no light into the device. Is there anything Im doing wrong trying to make it word with a new SD card? The LM5 was working fine one hour ago, but it will not work together with the enw SD card. 

The ond SD card got some memory damage, and its tolate for me to run a backup as I restored it before I read in the guide taht I should take a backup of it. 
I have a backup from the settings in the LM5 if I get it to work again.
