Hello, I have a question . Since I have not completely followed the course, I hope someone can give me an answer. I have a working wii u with haxchi / ds game and a second wii u which has been formatted (160-0101). Can I do a complete mirroring from 1 to 2?
Thank you for your support
Right now there is nothing you can do without seeprom or otp.bin. read my guide in my signature. As mentioned earlier there is a well respected member of the exploit community that is currently working on obtaining access to areas of The Wii U that may help you in the future. As of right now, even with a teansy, there is nothing you can do

Hello
I have a bricked Wii U here after CBHC Cooldboot.
After install a game to USB the Wii start in the short menu but doesnt start to system or normal menu hanging in the autobootscreen and display say -5 or without a SD card -3.
I make a backup before CBHC from the nand : opt, seeprom,slc,slccmpt,mlc part 1-3 (4 was withfailure).
Now i have a chance to repair the Wii U?

Sry for my bad English

You shouldn't have installed CBHC to USB. But all is not lost. Buy a teensey++ 2.0 and read my unbrick guide. It's in my signature.

CBHC should always be installed to nand. You can't install it to SD


If you have otp.bin you can just dump seeprom with teensy++

If you get -5/-3 it means that CBHC is working but fails to load some file from the SD. what was your autoboot option? did you have mocha?

Are you able to get to the CBHC menu by tapping the home button on boot? Wait until you see some text on your gamepad while cold booting and then press home. You should be able to change your autoboot option to system menu

My autoboot option :

a=fw.img
b=wiiu/apps/homebrew_launcher/homebrew_launcher.elf
default=sysmenu

mocha was installed before CBHC

That's a HaxChi config not CBHC. If CBHC is working you should be able to get to the config menu by pressing home button once when you see the words "autobooting" on the gamepad.

Also if you're able to launch the browser from the quick start menu you can fix HaxChi and CBHC. Just make sure that your HaxChi is on the Wii u nand not on USB or you'll brick (if you haven't already)

Dumping SLC at 100kb/s, quite slow. TP138 is connected to VCC but you will need a external power supply, teensy can't handle it.
It is easier to just power on the console with some hardware removed.
-----------------------------------------------------------------------------------------
Edit Having trouble dumping EMMC
Resistor 30 (DAT2) 33 ohms
Resistor 29 (DAT1) 3.1M ohms
Resistor 28 (DAT0) 33 ohms
Resistor 31 (DAT3) 3.1M ohms
Resistor 27 (CMD) 33 ohms

Single DAT line dumping works, but if i connect DAT1/2 and 3 it fails with a Device Not Ready error. Does anybody has the correct values for these? I think 29 and 31 may be busted.
Reader: Alcor Micro USB 2.0 Card Reader
---------------------------------------------------------------------------------------
Edit 2: Done with all SLC and MLC dumping, 2 good verified dumps :grog:.

@Leeful could you please add a large warning on the first post? DO NOT try to solder on the top of the resistors, i just barely touched them for less than a second with pre tinned wires and a 25w iron and 2 of them died instantly, then i redid the wiring and the rest died as well. Had to patch them after.

Hello. Please help. When the system was updated, the lights were turned off. There was an error 160-0103. The NAND is damaged, when reading, it gives an error of 97%.
PLEASE, give backup 8GB NAND. I want to try to update through a hex editor and fill it with a new NAND chip (not damaged).
About the fact that the dump does not fit, I understand.
Also, I'm saving the data security (it's not getting farther from my computer).
Sorry for the bad english. I work through an interpreter.

I don't think you can replace chips as there is an hmac check? i am not sure how that works. Even if it worked you would need a backup from a donor console from both SLC and MLC. And that is all assuming you got otp/seeprom dumped + knows how to do it.

Hey guys, you appear to be able to get files from broken wiiu.
What i want to do is buy a broken wiiu and dump the required files from the nand in order to play online with cemu, that would greatly reduce the cost.
Could someone guide me a bit with the procedure for this ?
Also is there a way to check if the nand is undamaged? (because the wiiu i will buy will probably be in a really poor state)
