I’m trying to update the firmware of an TP600 HMI (762-4203/8000-0001) from FW28 to FW30 using WAGOupload and during the updating process I get the error: “**Could not start update. The firmware mode is disabled (95)**“. Any idea why or what went wrong? Thank you!

Hello,

I’m not certain about that specific error. I would recommend to alter the update format and try to use an SD card with the fw image file to update and see if that nets you a better result.

Using the SD card fixed the problem. Thank you!
