Samsung gear s2 sm-r720 reactivation lock

Today came to me gear s2 SM-R720 with reactivation lock. It doesn’t have normal usb port (we can charge it with induction charger), but when i disassembled watch it shows that we can solder usb interface. By home button i can go to download mode with usb interface. In attachement is photo of disassembled watch. Is there any possibility to do some research?
