Broken Wii U with blue light and no video

[SDIO]

You swapped CMD and CLK in the analyzer. Your card behaves exactly like mine, till the Wii U increases the clock. After that your LA has no chance. So at least they can aggree on the mode of the bus. But I noticed that shortly after the activity on the CMD line seems to die down. We can't exactly see what's happening, but we see that CMD doesn't seem to change anymore. So maybe the Wii U is rejecting the SD card shortly after on a different criteria, like it did with my 64GB card.

Can you give me the exact size of the card in bytes?

I attached the CSV file from a successful boot for you to compare. After CMD9 in line 240 the clock gets set to first 25Mhz and after CMD6 in line 259 to 50MHz

Windows shows me a drivesize of 31.099.783.680 Bytes and a partitionsize of 31.104.958.464 Bytes.
The size of the Imagefile is 31.784.435.712 Bytes

EDIT: Sorry about the link, didn't see the Attach files button
EDIT: after switching the CMD and CLK the data looks much better

It shouldn't have any partition on it, but that might just how Windows shows SD cards. The card should have at least 31239176192 bytes so your card is slightly to small and the wii u is probably rejecting it because of it

Hi brother can you tell me from where you can buy this tools for fix wiiu coz i have same wiiu broplume.are you do this with no backup before?? Is it worked //Thank you

We are still trying to fix it. Yes i dont have a backup, i bought it used not working.

What tools do u need?

The sd card reader you use is it dump your file or what it help. You coz need more info.

I got a new Sandisk micro SD with 31.927.042.048 Bytes. Still nothing.
Attached the logic analizer reading.

Disappointing. I looked at the reading, but there doesn't seem much going on. Or maybe we just don't see it, becoause the LA is to slow.
The card doesn't have any partition on it, right? You just wrote the Image from the mlc to it, so Windows now thinks it is not formatted?
Can you compare the card with the original image you made, to see if anything changed?

 

[alexszymona]

What would be the best way to compare it?
I wrote the Image back using Win32DiskImager

 

[SDIO]

I am not sure what the best way on windows would be. Maybe some hex editor which is optimized for large files could do it

I dumped the SD Card and compared it with my eMMC dump, it's identical. Nothing got changed by the console

 

[SDIO]

Sorry, then I am out of ideas for now. The only thing that comes to my mind would be to improve the GND connection like I mentioned above. Also you could try to get the Power for the SD from a better location: https://gbatemp.net/threads/how-i-fixed-160-0103-system-memory-error.626448/post-10119405
But I don't think that that is the problem.

If we had the otp we could dump the slc and look ad the logs, but without the OTP we are blind. It's all encrypted and we can't look in.

@alexszymona You could try to use the pico as a logic analyzer: https://hackaday.com/2022/03/02/need-a-logic-analyzer-use-your-pico/

They claim 120Mhz, which could be barely enough for the 52Mhz eMMC.

 

[alexszymona]

Thank you for your help. Im giving up on this console.
After trying to measure something with the multimeter it wont start anymore.
It just flashes red after pressing the Power button.

I dumped the eMMC using the Raspberry Pi 3 B+. It took me about 6 hours.
Unfortunately i ripped the CLK Pad to the eMMC so i cant dump it a second time.
Can i check the dump somehow or should i just copy the dump to a SD Card and connect it to the board?

Hello @alexszymona , could you explain a little more in depth about how to dump eMMC with the Raspberry, thanks

Did you try changing the battery? A dead battery will prevent this method from working.
I fixed mine with the exact same issue as you, but my battery was also dead.
