Huh, intersting

Brother's driver install tool expects dnf, apt, or yum, and so it's incompatible with ostree-based systems like Kinoite or Silverblue. You can of course download the driver manually and install the necessary packages:

Not being able to provide support for every distro is the other edge of open source

Your phone has a snapdragon which is very popular chip to make ROM for but generally hard to unlock unofficially -not impossible though it's possible there is a workaround by now for your specific chip - on the flip side mediatek devices are less popular due to them refusing to provide the source code but to their partners. however they are well-known to be easy to unofficially unlock due to some vulnerability -in the bootloader- that they refuse to patch.

I did a leap of faith and I unlocked my phone unofficially (mediatek) but if you decide to flip that coin think hard about it and make sure you are well informed (like using your specific phone code name instead of brand name ex: instead of redmi 9 say "lancelot")
