I've just tried to update my BV9000Pro. It was in response to the system automatically inviting me to do so.
Download went ok, unpacking, then reboot.. seconds later I get an image of a collapsed Android with the word 'error'.
I had to long press the power button, and restart.

Repeated process and tried again. Same thing.

What is going on? What do I need to do?

Thanks

What's your current firmware version?
have you tried to reset your phone?
please report then we will try to find a way to solve it .

I don't think you read question

All I ask is what is the change log of the recent bv9000 pro update.
