Help with transfering data from circuit board memory

[silviasol]

I am trying, hoping, to find a way to transfer data from one circuit board to another.  It is a ps vita(portable playstation console).  There is homebrew stuff like installing original doom on it if you have firmware version 3.6 or below.  So I have one board with 3.6 firmware.  Is there any way of pulling all memory from one chip and transfering it to another.  I have bga station, hakko board heater and hot air with wand holder/arm.  I have done bga reball all that stuff so am completely capable, for the most part...  Here are some pictures of the board.  I know there are cell phone stuff like pull the memory chip off then reprogram it with special tools.  Would this be possible?  Here are pics of the board and it's chips.  I came to you guys because you seem to know everything based on my other questions in the past

You're asking a very specific question but maybe there's another way to achieve what you want. However, you didn't say what it is that you want in the first place. I suggest you broaden the scope of the question and let us know

I haven't looked in detail at this particular one but a lot of consoles use DRM so even a full flash dump might not work correctly --- there's layers of unique keys and encryption involved.

So probably not worth looking into then?  I guess I should feel lucky I have one with the correct firmware, they are really hard to find these days.

From the second or so revision PSP there were different PCB revisions that would behave differently with the same software.
The earliest anomaly I remember was the TA-082 hardware which by the enclosure, was not distinguishable from other units,
but if you downgraded it below 2.5 firmware, it would brick (before even the first unbricking with battery & MS came about).

I wrote a pretty famous at the time program called X-Flash which customised wallpapers, text, audio samples, and other stuff,
before Sony included any mechanism to do the same in their XMB menu. It wasn’t till about 2.0 you could customise much.
TA-082 hardware could not run that program, and I ended up having to detect it and exit the program just in case.

That, and as already mentioned, your NAND will have data pertaining to some other serialised components on the board.
