* Vivo x70 Pro+: [xdaforums.com](https://xdaforums.com/t/vivo-x70-pro-bootloader-unlock-how-to-guide.4444989/)
* Vivo Y31 2021: [xdaforums.com](https://xdaforums.com/t/unlocking-bootloader-rebooting-in-edl-without-testpoint-vivo-y31-2021.4440801/)

\* BBK Electronics was deregistered as a company on 7 April 2023.
