Hardware Hacking [question] old 3DS bricked(bootrom error)

[ttaeung0217000]

BOOTROM 8046
ERRCODE: 00F800EF
FFFFFFFF FFFFFFFF
00000024 00000000

a... um...


i soldered nand pinout tap
DAT0 CMD CLK (GND)
and i readed nand and turned on

and this error displayed
so i removed wires and soldering

but it doesn't work!

and i writed pure nand file

still same screen

i soldered resistors near tap but still doesn't work
my body freezed
i need help
(sorry i don't know english well)
(and this is first post..)

Sounds like you damaged your emmc that why it won't boot since your attempted to hard modded look like you didn't hard modded correctly.

but nand read write works well with win32disk imager
i'm trying soldring with flux

Hardmod is dangerous (as you certainly know now).

Did the console start GodMode9 before (asking for the embedded backup here)? If this exists, try mounting the image with ninfs. This is to verify the image is actually okay (and the hardmod working correctly).

8046 Bootrom error is expected (with a different error code than yours) while the SD reader on PC is connected.

Please upload good photos of the motherboard. Maybe somebody here is able to spot a problem.

=====================

Whatever you wanted to achieve with hardmod: ntrboot would likely have been a safer and better choice. There should normally be no reason anymore to attempt hardmod on a 3DS

Why did you do a hardmod? Was the system working beforehand or was it bricked?

Error code he got isn't on that list.

this is motherboard

wait

errcode changed...?
i soldered those resistors

yes. before it worked very well

Still the same error code.

oops i upload another picture by mistake

this

 

[DrPickles]

Ok, so it was working. Again, why did you need to do a hardmod? Were there any other system issues, software issues, etc...?

If it is that you can try do NTRBoothax to fix it.

i just wanted to test new sd card reader(......)
i'm finding sd card readers to read emmc

i soldered again and errcode changed
likes this
and sd card can't detect 3ds emmc

Why you soldering it again?

 

[ttaeung0217000]

Why you soldering it again?

i wanted to solve this error
now i'm seaching problems pcb crack or cold soldering etc..

 

[ttaeung0217000]

i found something wrong
DAT1 connected at GND
i'm finding wrong point

 

[Mayo1990]

Why are you hardmodding a 3DS in this age and day?

 

[ttaeung0217000]

i removed quad resistor(dat0,1,2,3) but still DAT0 connected at GND
maybe
1. emmc BGA cold soldering
2. PCB crack
3. soldered itself by hot(?)

solution
1. remove bonding and reballing emmc chip (hardest)
2. connect another emmc chip (simple)
3. capture X ray(???)

i will try 2(new emmc)

 

[DrPickles]

Just buy another one and use a software mod. You removed a resistor? Why? How did you short your data line to ground?
