    Hello fellow modders,

    I received a customer's 3DS xl 4.4 with a regular blue screen error resulted from a gateway tempered launcher brick.

    The customer tried to do the NAND HW mod himself and ripped off the DAT0 pad.
    Warning: Spoilers inside!
    It turns out that this pad is connected to a resistor array through a connecting track and it was ripped off too.
    Warning: Spoilers inside!
    I did a wire jumper between what's left of the trace leading to bellow the NAND and the array pin corresponding to the trace without much luck!
    Warning: Spoilers inside!
    The console still gives me a blue screen error.
    Warning: Spoilers inside!
    I wonder what else I might be missing or if the resistor array is screwed up.

    Reading and writing to the NAND works perfectly. I wrote the NAND.bin, extracted it again, compared to the one I wrote and the MD5s matched.

    Any clues?

    EDIT:
    The blue error message appears after 5 seconds.
    A "regular" flashcart brick give us "instant" blue screen. You turn it on and the error message pops up immediately.

    That's what happend when my r4i deluxe version 3.3 bricked my 3ds xl and I tried to fix it myself I have good soldering skills but that doesn't matter when I dropped the mobo when I had it plugged in to the pi. I also ripped the pads off so I give up I still have everything. I was going to buy a mobo off ebay but never got a chance

    There is a documentation about ErrCode in BootLoader with NAND Loading here: http://3dbrew.org/wiki/Bootloader

    Looking for you error it look like the first but with 00400000.
    (Deixe me ver se entendi bem, o cliente raspou as trilhas da PCB ? ._. )

    Hey st4rk,
    "Deixe me ver se entendi bem, o cliente raspou as trilhas da PCB ?"
    You asked if the customer scrapped the trace... nope I did the that... veeeeery carefully and then looked with a magnifying glass. no shorts
    The NAND inside the console isn't "locked" by the brick. I've just confirmed by wiring the the SD cable and using my RaspberryPi.

    Yet, only I get is a blue screen error code.

    I'm thinking that the removal of that pad is perhaps preventing something else from reading properly. That's my educated guess for the day.

    I was looking at the resistor array with a magnifier glass and ***maybe*** the res array pin cracked and went off...
    can I just solder another resistor to "do the work of that one?

    Plus, any clues on that resistor value?
