Is a command you can do on your PC while phone is in fastboot that should still be able to enable oem unlocking ^^
So as long as USB degguing is there in dev options you should be golden
Not what youre looking after but-
I use newpipe as a peertube client, but since it supports youtube as well you can search yt music specifically and download a track in up to a 128kps .m4a of 160kps .opus file. I then use vlc for android to play em, and it works just fine :3
You may find a offline music player with a ui similar to vi as well!
Some minor gripes is that these files seemingly dont come with metadata, and you cant download a whole playlist or album at a time, both being huge bummers :/
To unlock your bootloader you need to enable usb debugging and oem unlocking in the dev settings. The rest of the steps are done in fastboot; a secret menu. From there you need to connect your phone to a pc with android sdk and your phones drivers installed.
Here it gets way complicated but the short version is that on the pc you use a tool called adb to make your phone go into fastboot. With adb you also ask your phone for a string, which you send to its manufacturer, who then hopefully sends a more different one back. That last string is then used to unlock the bootloader
Android at its current best is neat, but often vendors will have their tweaked rom which hide or break many of androids functions. For example, the stock MiUI/HyperOS (or whatever xiaomi calls it now) on my Redmi 13C doesnt have the option to view saved wifi networks in its borked settings app.
I hope this, together with custom ROMs seemingly keeping sideloading possible in the future, only helps with their popularity. Alternatively it would be really cool to see the mobile Linux community bloom.
Heard Samsung phones shipping with their OneUI 8 and onwards will not have an option to unlock the bootloader. Not a dealbreaker for many if you dont dvelve into rooting or installing other operating systems on your phone tho.
