Hello everyone,
I got an EATON UPS 5p 850 (so no warranty) and tried to update the firmware but, after waiting almost an hour, it showed nothing on the screen and only the green logo was alight. So I unplugged it completely and since the fan is running but nothing is happening on the screen and no logo is lit. Do you have a solution to put the firmware back in the UPS ? I'm not ready to pay for repairing it...
Thank you.
