My boox note does not turn on anymore

Hello,
my boox note does not turn on anymore. I updated the firmware today, after he crashed for the n-time while I was using the note app.
Now it does not turn on. I tried to press exit button and power to enter recovery mode but nothing happens. I bought it in September for nearly 500 £, i am getting a bit disappointed because in less than 3 months is already not working anymore.
How can I do? please advise
Andrea

Hi, have you tried factory reset?

In some previous threads users had similar issues, the resolution was charging the device for a long time with a capable (more than 2Amp) charger.
