I have a DSO201 V1.
I have tried updating the firmware, but now when I turn the device on, I get a white flashing screen.
Any ideas?
The FAQ and a couple of the last 10 posts in this forum should give you some ideas!
I installed 4.22 and all is working fine now 
This is a new Issue on an older thread:
Nano Version 3
DFU Version 3.26D
I have tried a few times to load new firmware and now my unit only will boot to the DFU screen. It doesn’t matter if I hold the down arrow or not.
Been trying firmware from here.

But have also tried the factory 4.22.
The update that killed it was attempted from a windows PC. After many attempts the drive stayed active long enough for me to drag one file there. Could never get the second file to load. I cant remember if I did the AP or the LIB first. I may have restarted at that point.
I have since been trying to load from a linux machine. From there the nano is at least visible as a drive. I’ve tried the latest releases from the forum link above.
Is this thing a brick now?
I would appreciate any help.
