@nsfilho Not very long, 3s max. I didn't know that, thanks for warning! The problem keeps reappearing so I will keep that in mind.

Hi. I just want to say that I was able to solve this strange issue with the BAT - GND cable trick. It didn't work at first and I was getting only two ports from nsfilho's script. But then I figured it out. I just had to turn the device off by holding the power button for 6s first and then the cable trick worked.
