Dead phone keeps connecting/disconnecting on PC by USB

Hi, few days ago my sister's phone fell from about 1m on the ground and from this time it's dead. Screen all the time off, no vibes etc.
The phone is iNew v8 plus.

I've disassembled it, unpluged and pluged all cables, checked if hardware buttons are working(by multimeter, they are working), etc. but still nothing, phone is dead.
Today i've connected it to my pc and seems like it's not fully dead, because in Device manager it's visible as USB Modem Driver(COM3), it's connecting for about 5 seconds and then instantly disconnecting, and again connecting... endless loop.
Device is not visible for ADB,

Do you see any chance in at least recovering data from phone?

Thanks in advance
