JBL Flip 4 USB board
Hi, a friend of mine gave me his flip to repair because he broke the usb slot.
I don't want to buy a new usb board as it's too expensive for him...
I tried to connect directly a usb cable so he can charge again the flip but it doesn't work?
here is what I tried :

and here is the usb board :

do you think it's possible to connect directly a usb cable to the flip without the usb board ?
thax !!!
