Seems like a pretty articulate explanation of what is going on here. Of course I realize that my confirmation bias will cause me to see articles more in line with my way of thinking as 'right' but I've also worked with NAND flash devices and believe that the chip[1] they use in the phone does not have any sort of protections on the NAND flash itself, you should be able to just drop it into a test fixture and read it out.
