Hacking Hardware Need help with fixing bricked Wii U with Raspberry Pi Pico

[Infragno]

Yes, I know. Compared to a known good board the values of Q5 are a lot higher.

I mean does anyone know the exact component. Like the model number or a compatible replacement.

I have a smd station so I can replace small parts. (Doesn’t mean I know a lot about electronics, just the basics. But I can solder pretty decent )

If not I will just get the 5V of the buck converter.

I would assume probably almost any bipolar transistor with the footprint would work. You can measure on the good board if it's pnp or npn.

I couldn’t figure out wat was broken. Swapped over R77, Q5 and D7 and still didn’t work. All the other components seem fine and the same as my other board. Also voltage is good before it goes to fan circuit. Swapped back and the other board fan is still fine. So connected to buck converter and I consider it fixed now.

Thanks for all the help.

I have a question about rebuilding SLC and MLC.
Would it be possible to restore a SLC.bin / raw (from a freshly recovered console) on another console with minute? And then rebuilding / syncing MLC? Or is the SLC completely unique?

No, each console has their own encryption and hmac key for the SLC and the other NANDs. You would need to re encrypt it first. But why would you even want to do that, since it seems to work with your backup?

Because I had some problems using the guide for rebuilding SLC and MLC. I want to try another console with a new pico and sd card and see if I hit any problems.

I found it somewhat weird that restoring SLC.raw before rebuilding SLC / MLC was the solution for this console. (Why would that even work).

Since the MLC Restorer / Downloader program and JNUSTool use the common key, I assume the 57 MLC / SLC folders and ios_orig.img you get are usable on all consoles of the same region. (?)

Will start from scratch and share the logs before I begin. But I would like to install a nand-aid even if it’s not necessary.

Yes, in fact the firmware downloaded is usable across all consoles in the same regions.

Hi! I'm back

I hit a simular problem, but I can't seem to fix it. I double checked the nand-aid installation and it seems to be fine. But I do get this "SDHC error" when I print MLC information. I copied what happens when I try to restore SLC / MLC to error.txt. Any help is greatly appreciated! Thank you.

 

[SDIO]

That error interrupt is normal and expected. That happens because the clock is stopped for a moment when the frequency is changed. Normally the interrupt would be masked, but minute doesn't do the masking.

The and for your problem: either you have ISFShax installed (and miss the plugin) or your slc has corruption.

 

[Infragno]

I’m using a pico to run minute.

The console booted before, but gave the 160-0103 error after a while. There was media error in the log. First thing I did was make a back-up of the SLC.

If the SLC is corrupted, can I rebuild / fix it?

And what would be the fix for the missing ISFShax plugin? Does this apply when running minute of the pico soldered to the board?

You would just add the isfshax plugin to the ios_plugins folder. And yes you always need the patch when ISFShax is installed. The patch makes IOSU ignore the ISFShax superblock. Else IOSU would try to use the ISFShax superblock, which will fail, since it isn't a real superblock.

It seems your files on the SD is outdated anyway. YOu probably used the defuse package, which is not that uptodate.
You can just use the release files from the https://isfsh.ax. Make sure to remove the old wafel_core.ipx when updating.

Okay I was doing fine until I wasn’t. I tried removing the micro sd from my nand aid and I damaged the R26 trace coming from the nand. Trace is gone. Is there any via I can solder to?

Also what are the values for the resistors and are they necessary?

I got it working. I bridged the gaps and found a tiny bit of trace to the eMMC from R26.
