Ledger Flex locked up. What next?

My Ledger Flex froze in the Ethereum app. I held the power button for 5sec and it went into protection mode. Anyone know why it did that? Looks like it'll be a few hours before I can use it again. What's it doing in protection mode?Is there a way to reboot the device without triggering this?I just updated the OS. Hadn't noticed the problem before that. via /r/ledgerwallet https://ift.tt/TxOzbhv
