Do I have to relocate the NAND, or is my Wii completely dead?

[vyxxn11]

Hi everyone, posting to ask for some help with my Wii trim. I tried to start making a Wii portable a few years ago, when I was 14, but I was largely unprepared and hadn't done enough research, so as soon as i started working on the batteries, i shorted them and broke the PMS...! Needless to say, I put the project aside until I felt I was better prepared and ready to pick it back up.

Recently, I decided it was time to give it another try... I expected the trim I made when I was 14 not to work, but I guess I was just hoping that something would happen and it would actually work, so I wired it up regardless. Connecting it to the screen, it gives no composite output (as expected...)

The thing is, I'm pretty sure that when I trimmed the Wii I cut through some NAND traces at the top of the board, so I'd greatly appreciate it if someone could take a look at these photos and tell me if by relocating the NAND this board could be revived or if there are other problems I haven't noticed and it's dead for good.
Thanks.

(also pardon the mess, in a few points there's some 3+ year old solder that i haven't removed yet lol)

Well,I guess it will work because you can actually trimm the wii really small(check this:https://bitbuilt.net/forums/threads/lmaov2-and-nand-relocation-guide.1961/),but jeep in mind it's a very tricky relocation and,even if you complete it,it's possible that your Wii have other issues,so I think you will save a lot of time of troubleshooting this.But,if you really want to do the trim on this one,take your multimeter and check the resistances on your wii,here is a guide.And also make sure to clean your board,it always help a lot

Hi guys,

since a lot of new ppl try trimming wiis, i was thinking about collection some common questions & data. So i've started writing down my latest voltage resistances.

I hope some of you could add some more with different trims & revisions!

It's an OpenDocument Sheet, but Excel can just open it fine. The archive also includes my first two measurements.

Also: Please only send me values of working trims or otherwise mark the non-working ones & read the notes before measuring!



//Edit 1: Wii-Mini trims would also be very interresting. So simple select trim-type "Custom"...

You have indeed severed some of the NAND traces. You can make it work again if you use some magnet wire to reconnect the flash chip legs to the vias for the severed traces. Pinout here for your reference

take your multimeter and check the resistances

Thanks, I actually already spent a while checking all the resistances, and I cleaned with some IPA, checked voltages etc. so I knew it was probably those NAND traces

TY Stitches for confirming my suspicion... I don't know why I didn't think of connecting the individual vias instead of moving the whole thing lol.
Also thanks for the pinout diagram .

Reconnecting them will be very fiddly. You'll want a magnifier, a fine chisel tip, liberal usage of flux, and a lot of patience.

Update: I followed the advice, wired everything back up, and now the wii boots up! Thanks again, @Stitches
