Factory reset:
• Obtain a USB Thumb Drive
• Format it as “FAT32” using the MBR partition table. Please note that MacOS often uses a different partition table by default! Please make sure to select the MBR partition table when formatting.
• Download this file http://repo.volumio.org/utils/factory_reset
• Please use Google Chrome or Firefox if the download doesn’t start automatically
• Copy it on the Thumb Drive (make sure the name of the file is exactly "factory_reset")
• Turn off the Stream Box S2 Ultra and unplug the ethernet cable (if connected)
• Plug the thumb drive to one of the USB ports
• Turn on the Stream Box S2 Ultra
• IMPORTANT: During this phase the unit might restart multiple times and this factory reset will take about 5 minutes.
• The factory reset will be completed when the Net-LED starts blinking again
I only needed this one time.
