PS Vita NAND gets dumped! is Encrypted
Yifan Lu, a hobbyist developer and reverse engineer-er has managed to dump the Vita’s NAND. This is the first occasion in two years that someone has successfully dumped internal NAND of the PlayStation Vita. That being said, Yifan Lu found out that the NAND is infact encrypted. So any direct modifications to NAND dump wont work unless the contents are first decrypted.
Yifan Lu also revealed several other specifications about the NAND flash. Its 3.7 GB in size, out of which the Operating System of Vita takes 808 MB ( pretty sizable as compared to PSP’s 21 MB flash0 ).
This project is pretty amazing considering all the hardware hacking involved and the fact that Yifan Lu managed all of this within weeks. You can read about the dumping procedure and his findings on his blog ( linked in source ).
As far as future projects go, Yifan Lu says
I’ll be looking into other things like the video output, the mystery connector, the memory card, and the game cards. I’ve also sent the SoC and the two eMMC chips I removed to someone for decapping, so we’ll see how that goes once the process is done. Meanwhile, I’ll also work more with software and try some ideas I picked up from the WiiU 30C3 talk.
This looks pretty promising and I’m sure that this is one important milestone in PS Vita Hacking scene.
