Posted 3 December Try looking at this link: https://support.industry.siemens.com/cs/document/19701610/how-do-you-do-an-operating-system-update-on-operator-panels-or-perform-a-reset-to-factory-settings-?dti=0&lc=en-WW Go to the bottom document called "Operating System Update" and "Reset to Factory Settings" with ProSave (Stand alone)" If the procedure to do "Reset to factory settings" does not work with Ethernet, you may have to try with a USB/PPI cable, but there is no guarantee of success because your HMI might be defective.
