    My daughter upgraded my o3ds xl to 9.9. I was set up with 4.5 sysnand and 9.9 emunand.
    I tried wiring the testpoint to flash my 4.5 nand.bin back....

    I F%^KED UP...

    I didn't understand completely the sd to usb adapter and I wired a mini usb to the test points and plugged it into my usb port instead of running an sd card reader in between.

    Anyway after checking my pinouts after I wired...

    mini usb

    Pin 1-- Data 0
    Pin 2-- Clk
    Pin 3-- Cmd
    Pin 5-- GND

    I think my issue is the whole 5v to DATA0.....
    I get nothing but a blue power light and black screens.

    Is this repairable?

    Not unless you swap out the whole NAND chip, it got fried when you fed it that voltage.

    I would usually say it's a fried chip. What perplexes me though, is it is still giving a black screen. The couple I've seen that USB fried the chip had blue screen errors.

    off topic but sort of not I had to restore my Nand and have Update Emunand again but what's the highest supported version I believe it was either 9.5.0-22 or 9.5.0-23 ?

    I wasn't booting the 3ds with it plugged into the pc.
    If I booted it with nothing in the mini plug, it booted to the home page.
    If I plugged in the usb plug into the mini usb plug i wired to the 3ds and booted the 3ds, I would get the blue screen.
    Then I would plug the usb into the pc and get the unrecognized device error.
    I replugged in the usb to the pc a few times and a few different ports....same results.

    I shorten the wires from the testpoints to the plug and double checked the connections and pinouts.
    That's when I read the whole sd /usb thing and WHY? I disconnected everything and booted the 3ds to black screens.

    yeah one guy has at least (although he completely wasted his time doing so as he could have just dumped the nand's from each 3DS and swapped them over the way)....but yeah he swapped the actual emmc chip completely while doing his region swapped small n3DS

    but the truth is is impracticable for most people unless they happen to have professional rework stations or know someone who can do it for them, for the average person it would be more logical and cost effective to just buy a replacement motherboard

    Swapping out the mobo is more the direction im thinking. I'm trying to score a cheap parts only one on ebay.

    I installed 9.5.0-23U to my emuNAND this morning. Working fine, no black screen.

    I'm sorry but why is your emunand only working to 9.5? I updated my emunand to 9.9 and it worked fine with cfw... What setup are you using?

    ffs.....sigh

    I bought a o3dsxl off ebay. It had a broken top screen so it was cheap and all I really needed was the mobo.
    I manage to merge the 2 3ds's into a one working unit only to realize that its sitting on 9.7....:/

    I'm screwed...lol

    What do you mean swap dumped nands? I thought a nand.bin is specific to each 3ds

    Nevermind... he swapped both chips. I get it

    He meant the entire NAND chip itself not the file on the nand.

    in his case he was swapping the CPU which is what ties the nand to the console, so he could have swapped the CPU, then used a SD reader to swap the nands over rather than physically swapping over the emmc chips (would have made the job quicker easier and less risky)
