C4 DOIP Update

This C4 Clone does not have the tray for batteries. The shaft for batteries is empty, no Cables are going to that. 

Can I inject the 9V (6x1,5V) directly to the Board so the C4 thinks there are batteries?
If yes, do you have pictures of opened C4 so I can see where the wires are going to?


I have also set the update minimum voltage in Toolkit.ini to 0.

Strange thing is that the other MUX is showing the Update Packages from the update_manual folder and this one not?


Kind Regards

set 0 then reboot c4 then can update if hardware is good.
