There is no such thing as a factory reset button on the DSO QUAD but it is possible to load the various software components and recover it from almost any software corrupt state.
There are basically 4 different types of sw loaded onto the QUAD
1 DFU This is the start up code and also the means to load the other software components. One should never need to change this normally and it is best left completely alone. If it does get corrupted then it is possible to load it back on by opening the device up, attaching it to a PC via a USB serial cable, and using low level flashing utilities as detailed in other threads.
2 SYS This is a bit like the equivalent of a BIOS in a PC. It provides access to the hardware components in the device like the screen, disc storage and data gathering side of the device. Updates are done by using the DFU loading a hex file
3 FPGA This is a binary image of the instructions that get loaded into the logic array in the device to control primarily the data gathering, FIFO queues etc. It should not normally need updating too often unless one is trying to make the hardware work in a different way. It is loaded via the DFU but comes in two parts; a binary file and the address file which controls where to put it.
4 APPS This is normally the most interesting area for updating as it controls what the device actually does. Normal APPS provide various versions of the main Scope application and others can provide different functions like logic analysers or script based measurements. These are loaded via the DFU using Hex files.
The first thing to establish is what state your device is in. Hopefully the DFU is still intact. If not then you will have to check out the DFU recovery mechanism.
What state is the device in if you just power it up normally, no pressing of buttons? Does it show a splash screen? Does it end up in a normal scope application? Can the Mac or PC see the normal USB data disk? Note that this is completely different to the DFU disk you see when the button is held down during start up.
Then what happens if you try to bring it up in DFU disk mode by the button hold during power up. If possible try to use a different Windows like 7 which may have a more predictable response than 8.1
