So few days ago i decided to send my slim to flashing. And they changed me PCB and flashed to 1.92. But with this i dont have dummy.bin which as i know is required for further upgrading...When i asked them which pcb is if is TX PCB they said its changed microsoft pcb. So i want to ask how i am now able to re-unlock it to get dummy.bin to i will be able to flash my self. (I Have all what i need X360 USB, CK3 Pro etc...)
