I used the recent app. The LED of the hub was dead after the update. I closed the app and after that I unplugged and plugged the hub back again. Same result as before. No LED, no reaction of the hub. I can't do anything.
The only reply I got was via Kickstarter messenger. They send me the same instructions to update that posted here. I should update on Bluetooth mode again. So funny because the hub doesn't do anything after the update. I even checked the power plug but that's ok. I'm really pissed of right now.
