2. Turn on your Windows PC, make sure the UUU tool is downloaded, and unzip the Yocto 5.0 OS image file.
   
3. Open Command Prompt (cmd) or Terminal as Administrator, then use the cd command to navigate to the unzipped folder directory.
   
4. Execute the uuu.exe 250114.auto command and press Enter.
   (Note: 250114.auto is the auto script filename. Please adjust the command according to your actual .auto file name.)
   
5. Wait until “Known USB Device Appear…” is displayed, then connect the EBOX (without power attached) to your Windows PC using Cable A.
   
6. Connect Cable A between the EBOX Mini PC and the Windows PC. The Windows PC will then automatically flash/copy the Yocto 5.0 OS image file to the EBOX Mini PC.
   
7. Once the restoration process is completed, remove Cable A from the EBOX Mini PC.
   
8. Use the jumper switching tool to set the jumpers back to Internal Boot Mode.
   
9. Power on/Reboot the EBOX-IMX8MM to boot into the Yocto 5.0 desktop.
