If anymore info is needed please ask.


In order to narrow down the issue, I think first we should gather as much info as possible!

  • what operating system are you using
  • what version or versions of etcher have you tried
  • have you confirmed that you get the same issue with multiple SD cards/SD card readers/USB sticks
  • does this happen if you try to flash different images
