M3 -- Os to sd problem for all

For all who have problem to write an .img file to sd I’ve try this way and is 100% Ok with “-” file.

1- download any zip.OS to your desktop 2- open the zip file to view inside the zip 3- simply drag and drop to you desktop with windows (I use virtualbox on linux to make this) 4- rename the “-” file in to"YOURFILE.img" 5- with linux you can simply use Disk to write .img on your sd card

That’s it !!!
