Iíve mentioned a few weeks ago Yifan Luís ongoing experiment/attempt at looking at the vitaís hardware. Yifanís been busy over the Christmas period, looking at the bowels of our favorite portable console. Earlier today he announced he was able to dump the Vitaís NAND.
Now before everyone gets excited for no good reason, all this really gives us today is confirmation that the vita onboard memory is encrypted. This in itself is interesting though, as this confirms Sony didnít mess up their security on that point, and attempting to hack the Vita by modifying the NAND directly is not a possibility.
Yifan also shared a bunch of cool pictures and explanations on how he achieved the dump, something that I think is extremely valuable for all of us, especially those interested to know how hardware hacking works. As Iíve stated many times now, I believe Vita hacking will not come without massive help from hardware hackers.
Some of Yifan Luís interesting findings are that the eMMC NAND is about 3.78GB, with about 800MB used by the (encrypted) system, and the remaining 3GB or so potentially empty for now.
This experiment gave Yifan Lu new cool hardware skills that heíll use to look at more stuff in the Vitaís internals. He also details the hardware cost of this experiment, something youíll find interesting if you want to do something similar one day
Oh, and this goes without saying, but yifan Lu will not publicly disclose the dumped material. Not that it would be useful anyway, given that itís encrypted.
This might sound like a disappointment, but to me, the fact that one guy went from no hardware knowledge to being able to dump the NAND of the Vita in a matter of weeks is extremely exciting. Again, more important than the result is how he achieved it, a process that he details on his blog. I wish I had the time to do the same
