I just experienced this same exact issue and there was no success in getting the screen to go to home. As soon as the PLC is turned on, it tries to read the data on the SD card and then comes back with the error message. I even tried this method without luck : https://support.unitronics.com/index.php?/selfhelp/view-article/unistream-recovery-to-factory-settings-procedure
