Hardware (Theory) 3ds dual-nand hardmod

yeah i would say next test would be wiring the emmc back to the 3ds and testing it it will boot, that will rule out any sort of damage to the board in the removal process

For reference sakes

Yup that's next on the list when I get some time, I traced back Vcc already to a couple points on the board from the chip area using the diagram in the SanDisk eMMC datasheet. The 153 BGA package has about the same layout (figure 7 page 18).

Soo i was thinking this over work and tossing the the idea around in my head with my o3DS (never going to use that thing again?) Anyways I decided to mess with it, so far I've removed the the BGA but stupid epoxy and my impatience ripped a couple of the points straight off the board.

I plugged everything back in and booted it of course it was a blue screen, I then hooked up a SD adapter to it and wrote an image to the microSD card.

But as it would have it, it still bluescreened so I am going to try and figure out what went wrong here, it could be anything really But hey it turns on (kinda?) after being pre-heated and soaked to around 200 * C and a hot air station was used to remove the chip (not the best method I know)

I'll say it again ideas lead to progress. Maybe a idea here instead of soldering to the test points why not solder to the NAND pads under the chip. There's a lot going on under that NAND maybe something we are missing

I check the continuity between the BGA and the test pads and it seems to be just fine, I'll poke around if I get some time tonight again.

Nand mod FPC complete (In PCB artist at least). Now need to compare prices between fabs more news to come

more news to come? april 19th? i found this really interresting and i'm eagering to know more! is it just that this thread is dead or is the project dead?
