#Samsung devices from today can no longer install custom ROMs.

Odin is gone and the Download Mode is also gone, which makes life hard also for repair services that want to restore a device.

This is your daily reminder that #Android is a liability, and major hardware manufacturers who ship Google’s version of Android are a liability too.

We need to get Linux phones to work, and we need manufacturers who are aligned with our principles.

@fabio I'm totally on your side with the urge to move to Linux phones. But in this exact situation Linux mobile operating systems do not help at all IMHO. If you can't install a custom ROM you can't install a Linux OS either
@j_r at some point we must get hardware manufacturers onboard too - and some hardware manufacturers will probably be willing to join too in order to conquer that niche, see Motorola
