Possibly relevant xkcd? https://xkcd.com/927

Omg I completely forgot they had a proprietary flasher, yeah that makes it much worse.

E: wasn't there an open source implementation called Heimdall?

How is it being a samsung making things worse? I've never flashed a samsung phone before so I may be very wrong, but isn't unlocking the bootloader easy?

And now that I think about, does samsung have their own system file format or something? Is that the issue?
