After that latest update, i cant use my flipperzero anymore. if i disconnteced it from my computer, the screen goes black and it wont start untill i plug it again with usb-c.
My batterij = is a 100%, already did reinstalled the software from the flipper few times. Anyone know how to solve this problem?
