Renamed satip-axe-201505242057-9.usb > idl4k.scr
Formated an usb stick with FAT32 and copied both files to the stick
Power off Megasat device, insert usb stick in the only usb port, powered on.
Still boot original fw, soft reboot trough web interface, still boot original fw.
Tried satip-axe-201504211434-8 files, same thing.
Tried another usb stick, same thing.
Tried formating usb stick w fat and not fat32, same thing.
The USB device lights up and if I in the original webgui select firmware update it says usb device connected so the device is attached but does not boot...
Anything more I can try?
