iPhone 15 crashed and stays in bootloop after connecting to Voi E-Scooter with App

Hello,

so i bought my iPhone 15 (refurbished) over the Apple Store in December.

Today i was unlocking my E-Scooter and a few seconds later my Phone turned off and started boot looping.

What i tried:

Using iTunes to update and reset the phone.

Using Apple Devices to update and reset.

I tried this multiple times.

Got a bunch of different Errorcodes which told me to change device, change the cable etc.

Did all this. Nothing helped.

Maybe you guys have an idea what i can try besides that.

I made an appointment in an apple store for tuesday, but maybe I can solve it earlier with your help.

Greetings

Max
