So I have to find a USB drive that the bootloader will recognize.

Having assisted with many recoveries, when it’s a straightforward recovery which previous FW supports, not all USB sticks even when configured correctly will recover the instrument.
Another error that is sometimes made is not having the recovery files in the root folder of the USB stick.

In my generic instructions I also warn that a new USB stick might be required for recovery to be successful.

@All
Member contacted me today informing the 10th USB stick they tried successfully recovered their scope.

Why, IDK, maybe PC OS used but goes to show that when everything lines up successful USB recovery is simple.

During boot, the USB port seems dead.
There is no indication that the bootloader wants to access the USB port and the attached stick.
The LED on the stick does not blink even once.
Isn't it expected that the bootloader tries to access the USB port and connected stick?

When the boot finishes and the oscilloscope starts working, the USB port also starts working and reports that the USB stick is connected.
Of course, after a few seconds everything freezes.

The now very old 6.02.01.02 FW likely does not support recovery.

Instead we need use SD card recovery and the unit needs be opened to access the SD card slot.
Send me PM with your email.
