Old WiiU stuck at boot logo

[omeguito]

Hi, I relative gave me their old broken WiiU and said that I could keep it if I got it working. It is a Zelda Windwaker special edition so I wanted to give it a try. The gamepad connects and works OK, but the console is stuck on the WiiU logo screen. I managed to get UDPIH working, but without proper video output (the video is stuck at the WiiU logo), and I blindly navigated through the menus to get the syslogs. Here's the output:

00:00:08:403: mmc_core card err: idx=3, lba=55396352, blks=1024, xfer=0x1, ret=0x00200b40
00:00:08:440: mmc_core card err: idx=3, lba=55396352, blks=1024, xfer=0x1, ret=0x00200b40
00:00:08:440: mdblk: err=-131099, mid=0x90, prv=0x5c, pnm=[HYNIX ]
00:00:08:459: FSA: ### MEDIA ERROR ###, dev:mlc01, err:-2228230, cmd:11, pathnull)
00:00:08:459: failed to read file /vol/storage_mlc01/sys/title/0005001b/10042400/content/CafeStd.ttf, err -196673
00;00;08;339: ***LoadShared - WaitLoadComplete(0,2442464) failed with error -196673 on file "CafeStd.ttf".

The WiiU is modified, but my relative said they mistakenly connected to the internet and it auto-updated on top of the modification. Does this error mean the MMC is dying or the updated screwed the files?

Thank you

That is clearly a bad eMMC

What a shame, is it there a recovery_menu that’s easier to dump the nand? (without video output)

I’ll try to rebuild it before attempting to use nand-aid

If you rebuild, it will work until it corrupts again.
There is a fork of the recovery menu that has an option to dump the MLC: https://github.com/jan-hofmeier/recovery_menu/releases

But you can also just setup redNAND as a permanent solution and even access the old old MLC from there to get your saves: https://gbatemp.net/threads/fixing-...-soldering-using-rednand-with-isfshax.642268/
