The urge to tear down the stack of cellphones I have and pull the boot flash chip hits me occasionally. It would be a substantial project, though, so I haven't done it. Yet.

You have to do things. You can't sit on project ideas forever while they become obsolete. A lot of things on my project ideas file became obsolete while I didn't do them, and that is sad. I even had enough time to do them but still wasted it on places like HN.

how far down the chain does the protection go? if you swap the flash chips can you just boot or do the other chips expect a signature upstream?
