[size=150]Hi if you get a white screen after failing to load .hex files, can copy original software back on and at least make it work again, the zip file is on this forum in several place, just unzip and you will have 1 hex file, drag it into you nano drive or copy and paste might work, my drive is E:\ when nano plugged into computer, of course you have to press minus and on switch to get in the correct mode, the zip file is in at least two messages on here if you can find it, look for file name below…good luck Fred.
Name of original software of pocket Nano Oscilloscope 201N4_21.zip
