Tomtom 6200 problem

[sleschgsm]

Hello, I have a problem with the device. There was no coverage during update via Wi-Fi. The update has been shaking off the voltage and the device has since not been able to turn on. Reset not helpfully, I tried to disconnect the battery. The symptom is this: it turns on, the word "TOMTOM" will appear, after removing the device and switching off. After connecting to USB, it detects the device but immediately disconnects. Is it possible to do something in the device. I will add that there is no guarantee for a purchase from 2 years ago.
Here is a movie with a malfunction:
