How to unlock GD32 chip IC?

SZOROD Technology Co., Ltd. provides GD32F105 microcontroller unlocking:
GD32F105R8T6, GD32F105RBT6, GD32F105RCT6, GD32F105RDT6, GD32F105RET6, GD32F105RFT6, GD32F105RGT6, GD32F105V8T6, GD32F105VBT6, GD32F105VCT6, GD32F105VDT6, GD32F105VET6, GD32F105VFT6, GD32F105VGT6, GD32F105ZCT6, GD32F105ZDT6, GD32F105ZET6, GD32F105ZFT6, GD32F105ZFT6, GD32F105ZFT6 05ZGT6
For the STM32 and GD32 series chips with soft encryption, we will first extract their internal programs through hard unlocking. The extracted program with soft encryption is not available, and we will crack the soft encryption program to obtain the correct and usable chip program.
Application areas of GD chips:
TW earphone charging case, earphones and hearing aids, portable medical equipment, nursing detectors, low battery applications, three-phase BLDC and PMSM motors, electric tools, robots and remote control toys, industrial automation, wireless infrastructure, communication network cards, industrial applications, safety equipment, lithium battery charging and analog front-end monitoring, sweeping robots, aircraft model four axis aircraft, energy storage, etc.
