That can't be right. There were a couple manufacturers that give downloads and detailed instructions for people who want to root, right?
I forgot which ones do that, but I remember that being a thing.
what i meant to say was samsung was
historically the least brown town.
ofc there are manufacturers like oneplus who don't even void your warranty upon rooting nowadays, but back in like 2012-2013 manufacturers were too busy trying to lock the bootloader and various other garbage that required exploits in the system firmware to even root. samsung never, ever did this stuff. they never posted instructions or details either but it was basically the same for almost every samsung device out there outside of maybe 1 or 2 additional settings.
