Its really a shame Huawei went for a closed source OS on phones (and probably laptops in the future if not now) instead of Linux or another open source OS (they even started with an open source version of their os). I hope this harmony os doesn’t take up in other countries or we would be going backwards.
thats a very fair point, I had not seen anyone else make this one But the problem is that in this case, this functionality was entirely undocumented. I dont think it was intended for programmers.
Now if the firmware was open source, people would have gotten to know about this much sooner even if not documented. Also such functionality should ideally be gated somehow through some auth mechanism.
Also just like how the linux kernel allows decades old devices to be at the very least patched for security risks, open firmware would allow users of this chip to patch it themselves for bugs, security issues.
