It sure does seem like Samsung’s been going out of its way to piss off the Android community with some very anti-user Galaxy Note 3 behavior. First there was all that shameful nonsense about region locking the handset against SIMs from afar. As if that wasn’t enough of an affront, now we’re getting word that Samsung is using permanent eFuses to record incidents of rooting/flashing and using that info to deny Note 3 owners the warranty service they’re owed.
Knox, you might recall, is Samsung’s security software. If the Note 3′s bootloader detects that it’s loading unsigned code – and hence, the integrity of Knox can’t necessarily be trusted – the bootloader makes an indelible mark on a hardware eFuse to log this event.
Unlike the flash counter that Triangle Away resets, this eFuse – assuming that’s what the Knox indicator is actually marking – is a once-and-done deal and should be impossible to revert.
That becomes a problem when Samsung is refusing to service phones with this flag set under warranty, as the company’s reportedly been doing. How did Samsung go from employing CyanogenMod’s Steve Kondik and providing hardware to the custom ROM community to this sorry state?
