Manual screenshots

OpenStage 15/20/40/60/80:

  2. Transfer the File to the PC: tftp -pl /tmp/screenshot.raw -r screenshot.raw

Automatic screenshots

OpenStage 15/20/40/60/80:

This mode is useful, if you need more than one screenshot of the phone. The screenshots are made with a small shell script, which automatically transfers the file to the PC. Unique file names are auto-matically generated.

Shell Script

FN=os80ss$(date +%Y%m%d-%H%M%S).raw
cat /dev/fb0 > /tmp/$FN
tftp -pr $FN -l /tmp/$FN
  1. Copy the script to the phone: tftp -gr
  2. Make the script executable: chmod 777
  3. Make screenshot: ./

Import the screenshot and save it in a different format

OpenStage 60/80:

Make sure that irfanView with plugins is installed.
