Pico dosen't boot

Just receive my pico but can’t boot it…
I pressed during the plug-in phase but nothing happened…

Just to be clear, you’re holding the button down before and while plugging it in, right? It won’t work if you plug it in and then hold it down.

Also, are you sure your microUSB cable carries data? There are as surprising number which only carry power. Do you have any other microUSB devices which you could use to check the cable?

Hi , thank you for the comment !
Yes I followed the instruction on the Website.

For the cable I’m not sure so I’ll check it

Thank you very much !! :)
