The thing is, Infnix Mobile is releasing good-end phones to customers, but their stock firmware is not as good as their vision, and they made it a lot harder by blocking Brom mode and not open-sourcing the kernel source. They released kernel sources for specific devices, but in recent times they have not.

Their last updated repo is dated September 10th. As for the Linux community and the latest legal implications, devices coming with Android 13 must release their kernel source, but they are not abiding by the law.
Which is affecting the whole open source community and the users of their respective devices. Hence, we are doing a petition for it so that this comes to their knowledge, they help us to make a better open source community, and their customers get satisfied as well.
