No.<p>Scare users about reflashing without having expertise in the field. Warn about not having any support, yet still provide some means to support them if they don&#x27;t heed the warning and fail, so they don&#x27;t brick the devices - keep a tiny emergency recovery-only bootloader that would allow to reflash system in any state.<p>But please don&#x27;t insult their intelligence and don&#x27;t deny their rights to control their own devices. Sure thing, there are plenty of stupid persons who&#x27;d wreck everything and then some. Heck, I hope I&#x27;m not too stupid myself, but when I first time flashed a router I screwed things up because of a typo. Let users end with the brick (they were warned, right?), recover it - or pay someone to do so - and learn.<p>The only real issue that&#x27;s in conflict with this is theft prevention. A legit use should be able to run any software on their device, but some don&#x27;t want to give that opportunity to anyone but its legitimate owner. The technological part for this is here, but that&#x27;s not a technical issue, but a purely legal one.<p>But please, don&#x27;t just shift the trust from vendor to some non-profit. Let the device owners manage their trust by themselves and have the ultimate decision on such matters. And for all the sanity still left in the world, let end-users still be the owners.
