70mai A 400

Good hour.
I use your products "70 mai A400" Please tell me what to do!?
I asked for updates, when I connected to Wi-fi, I updated, but an error occurred, I waited for 20 minutes until a "rollback" occurred - nothing happened. I turned off the car engine, respectively, the power was turned off and it turned off. After that, it never turned on. I read on the forum that you can update the device "directly" via a microSD card. It doesn't help.
Please tell me. Is there any way to restore it?

    Hi, thank you for your feedback. Do you mean that it cannot be turned on? Could you please tell me when did you purchase it? Do you have any videos to show this problem?
