Ah. Will do that.

Lazr1026 · May 16, 2024

you should be able to go back to the release minute now. it will also confirm the seeprom i am building you should work

skawo · May 16, 2024

Okay, well, I wrote the re-crypted SLC.
What does "flashing DDI from mcp_recovery" entail?

Lazr1026 · May 16, 2024

you should do it without defuse, since ddi flashing in mcp_recovery with defuse is broken

skawo · May 16, 2024

So if I understand right

Disable pico
Get the CAT-R updater and dd it to SD card
Power WiiU on with both POWER and EJECT
evoila?

Lazr1026 · May 16, 2024

dont remove the pico just yet, just put it in bootloader mode

skawo · May 16, 2024

Do I need the fabled serial cable to trigger the ddi flashing?

Lazr1026 · May 16, 2024

no, but its better to still have it now just in case you need it later

skawo · May 16, 2024

Hm, well, I don't have a computer with a serial port anymore, but I guess I could get one (which would be cheaper than the USB cable - unless you can put two of the FT232 USB to serial converters on each end?)

For now just getting this to work would be more than enough.
Not sure if I can find the required images for this, but I guess I'll try.

Lazr1026 · May 16, 2024

later on i can send you some ddi images, but it will be a few hours

skawo · May 16, 2024

Would be excellent, thank you.

It does get into this menu if I hold POWER and EJECT, so I guess it's ready to do the thing.

mcp_recovery!

Did you backup the mlc?

skawo · May 16, 2024

I did.
It fails to get extracted by wfs_extract, complaining about wrong wfs version.

I _would_ really love to see what's on there, so if you have other suggestions on how to dump the files or extract this dump, I'd love to try them out.

EyeKey · May 16, 2024

If you can send me the dump and the otp I can take a look on why wfs-extract fails to handle it. (For start I can work with the first 0x2000 bytes as they suppose to have the wfs header)

skawo · May 16, 2024

Sent.

It was a long arduous journey, but success* was had at the end

* - still needs a donor wiiu for a disc drive and drh firmware chip
** - the mlc was wiped just like the slc
