(help) yotaphone 2 brick after update

Last week, my yotaphone 2 informed that there is a system update from yotaphone. I downloaded and updated but then my phone cannot work. It show only black start screen with word "Android" until battery empty.
I tried to android recovery mode (hold power and volume up),
it show that the error is "e:cannot load volume /misc!".
And I do not know how to solve that problem.
Please help me!

Yotaphone 1 development

Visiting here from Sony forum. Thinking about trying a new phone, and I really like the specs for the Yotaphone 1, especially considering the relatively small size, but don't see much development happening. Is there more on the horizon, ( ROMs, etc.), or has the window closed?
