zenfone6 Phone Not boot starts
Zenfone6 purchased in August 2019 has stopped running.
A few days before it stopped, a restart occurred at a strange timing.
It has been weird since the latest update from ASUS.
I live in Japan and cannot speak English well. The phone I purchased is like an overseas model and cannot receive support in Japan. I did a lot of research and couldn't find a way to get support in Japan.
How can I recover from this condition?
