I upgrade firmware of my POP 2 this morning, since, it will be lock on blue LED.
impossible to connect or detect with PC or Phone device.
when i connect it on PC or phone , led is lightening 1sec in white (or very little blue laggon color) and black during 1 second & switch after during several hours to dark Blue!
not recognize by PC (no sound connection , not camera peripheric detected, no zxproduct detected as new or old device).
impossible to find with wifi
the scanner works fine juste before the update of firmware
i try 10 push on Play buttons as i read in some topics, but definitly dark blue LED again
