Hacking [Guide] Kafluke's HardMod CBHC Unbrick guide

[edizius2]

Hi all,
I have had checked all the wires / soldering spots, and they looked fine. But before trashing the Wii U i have desoldered the wires from the Wii U and afterwards iitried to switch in again (with Button, HDD, and vent connected). The led turned blue and the vent started to Blow.
Is there a teensy++ which does not work resp. where the wiring is different (i mean in respect to the bridges on the board)?

 

[edizius2]

I've resoldered everything and same problem again. I found out that instead of A0-A7 on my board PA0-PA7 is written. When I disconnect the bridge from PA0-PA4, and Connect only PA0,PA1 and PA4 (without PA2 and PA3), then rhe On/Off Button starts to blink blue. Is this OK? Which bridges are really needed?

 

[edizius2]

OMG... I have read in the Main Post "If you are only going to fix a CBHC brick then ignore points RB & CE" instead of "If you are only going to fix a CBHC brick then ignore points RB1 & CE1". So I assume RB2 and CE2 are needed?

 

[edizius2]

Connecting these wires had No influence either...

 

[LMMiranda]

I can restore memory (error 160-0103) without NAND backup? Don't exist nothing to done when this boot error stoped the menu acess?

 

[Sayora]

How exactly do you leave close the Wii U with the Teensy still accessible from the outside?

 

[SundayWarrior]

Hi. Some notice
1) go to device manager when teensy is connect, open com port setting and change rw speed to 128000 (dump/write operation time very less with it)
2)optical drive not need when all write/read operation in progress
3)wii u never boot when wires teensy solder on board - only blue light blink
4)cbhc remover not work if syshax.xex not creat on ...slc/sys/config. But with some modification aviable inject modified system.xml from pc.
If needed i can try write little guide with my modified CBHCremover.exe

 

[Sayora]

Wait, the Wii U doesn't boot if the Teensy is in, so you cannot leave it inside?

 

[SundayWarrior]

Yes. If teensy wired with wiiu board (without pc connection) - only blink blue light.

 

[Sayora]

Is there a way to make a switch or something to make the connection toggleable?

 

[SundayWarrior]

Check lines. If on of this going to gnd for freez effect then switch possible.
But for what? If software problem - easy fix. Just edit system.xml (check that default_title_id line including 0005001010040200 (default sys menu))
Anyway no tool aviable (at this time) for free edit slc.bin = no reason for "teensy inside"™

 

[Sayora]

I don't understand what you are saying. If you have a CBHC brick you can't edit system.xml

 

[SundayWarrior]

If you have a CBHC brick you can't edit system.xml

I have tool for that.

///add my modified programm (big thx for help my russian brudda - creker). Based on nandcbhcremover with little modification.
Ussage - check first page. All from cmd. Place with programm slc.bin, otp.bin and syshax.xml (fix system.xml, grab it from unpack slc.bin -> sys/config/ folder. If cbhc brick then edit default title_id to correct and rename file to syshax.xml)
In cmd >nand777 slc.bin "eur/usa/jap -one of this" syshax.xml
All look at this >nand777 slc.bin eur syshax.xml

After that extract its slc.bin with wii u nand extractor and check that system.xml chandge correctly. If all ok just flash to console fixing slc.bin

And again - sorry for bad english

 

[Sayora]

I want to know if it is possible to install the Teensy in a way that allows it to be switch off to allow normal use of the Wii U without having to desolder.

 

[SundayWarrior]

Firstly - try unsolder only gnd point.

I want to know if it is possible to install the Teensy in a way that allows it to be switch off to allow normal use of the Wii U without having to desolder.

It's been so long since I did it but I think @SundayWarrior is correct. You can connect a switch on the ground wire to allow you to boot normally.
Also I added another switch to swap between RB1+CE1 and RB2+CE2 so that I could choose to flash either my V-Wii part of the nand or the WiiU part of the nand.

 

[Sayora]

Is there any particular switch brand you would recommend? I don't want to get one that will break.

 

[baraka73]

I have Done! My Wiiu is working . (Unbricked)
But, i could't power on my Wiiu (instead of The power LED is blue and fan is spin.). The Power Led was only RED, however, I was able to write and read Nand's content.
I had a stranger thing - NAND chip type: unknown (0xdc) and when i was writing the NAND i had two verificaion error.

Thank you Kafluke for the guide and the advice of SundayWarrior !!

I havent tried to fix my Wii U yet, this is big for me, I just come to say that if someone from Spain with the necessary knowledge to carry out this guide reads me, please contact me by pm.
Kafluke and Leeful, thanks to you, I always hope to fix my Wii U at some point (I love the saved data)

Do you have a backup of your system NAND? If not your Wii U cannot be fixed by this.
