Firmware update fail


Recommended Posts


I have a 10.4" UniStream (USP-104-M10) with a CPU mounted (USC-P-B10). I attempted to update the firmware, and now all it shows is a red screen saying "The Update has failed !!!".  No amount of rebooting the HMI/PLC or laptop will recover it. I even tried the USB rescue procedure, but it will not budge from the red update failed screen... Can anyone help?

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
