Hacking Coldboothax - solving infinite loop with sysNAND CFW

[Masterwin]

We published this same a week ago and the admins erased it, now if they let coldboothax? I do not get it


Never mind, here I leave again the first guide of coldboothax.

excellent work ::hoenix::

My contribution is not a tutorial on how to install coldboothax, it is a mod to sysnand iosihax to be bootable by coldboothax. This is maybe why no one complained. Thanks anyway!

That's great to hear, dude. Your changes are awesome. Glad to see they've been merged into the official branch

yes, effectively, its modification in fw.img avoids the loop in iosuhax.
Our guide is designed for rednand only, now we are testing with your modification and modified cfwbooter, to avoid double loading, we hope it works.

 

[Mustacheboyo]

cool

 

[::Phoenix::]

It seems that also the allowed game region is read from sys_prod.xml by the iosu firmware, so it shoulde be possible to path region cheks with iosuhax, instead of modifing another sysNAND file.

 

[::Phoenix::]

Should have found where IOSU checks for the game region. Will try later if the patch works and will update my repo.

I am not close to my Wii U right now, is there some one willing to test the region free patch?

 

[::Phoenix::]

Seems I got regionfree working. This patch applies to every flavour of the iosuhax, being it redNAND or sysNAND. I have updated my git repository.

This is the only version of iosuhax for which it is possible to restore a coldboothaxed console to normal. Even with redNAND, the console is practically doomed to have coldboothax installed.

It is possible to remove coldboothax when u are using it to boot redNAND, when you have a possibility to boot HBL. For examble, this is my config.txt:

a=wiiu/apps/homebrew_launcher/homebrew_launcher.elf
x=wiiu/apps/ftpiiu_everywhere/ftpiiu_everywhere.elf
down=wiiu/apps/snes9x2010_libretro/snes9x2010_libretro.elf
default=fw.img

So I just replace redNAND fw.img with the cfw fw.img, then hold the button 'a' when the iosuhax splashscreen is showing up. Then I'm in HBL and I can modify my system.xml with wupclient.
But now I'm using your fw.img, thanks man.

Good to know! If you are interested, now I have got also region free in my iosuhax fork.

 

[Mustacheboyo]

so have you or Masterwin started working on fixing the double boot issue

I have an idea on how to do that, but I need to do some reversing to find where the fw.img loads the default title id.

@::Phoenix:: Could this https://gbatemp.net/threads/haxchi-boot-fw-img-from-nand-no-sd-card-needed.449769/ be used in conjuction with coldbootthax?

 

[Orion]

Also can I use the commands "make" or "make cfw" if I'm only wanting this for region free without editing xml files? I've already made the coldboothax(make cfw-coldboot) and will probably do it after I test my fw.img file first.

 

[Mustacheboyo]

yep and also do you mean make cfw-coldboot

@pietempgba can this fw.img be used just for signpatches and freeregion or is it only for coldboothax? Will it load the system.xml/homemenu or will it try to load syshax.xml every time?

Nvm that's only if you edit system.xml right? so it should function as all other iosuhax fw.img files right?

 

[Mustacheboyo]

it's for both here's part of the make script

cfw:
@$(MAKE) SECTIONS="0x8120000 0x5000000 0x5100000 0x8140000 0x4000000 0xE0000000" BSS_SECTIONS="0x5074000 0x8150000" fw.img

0xE00000000.s has freeregion in it

You enable coldboothax supporto (and thus lo ad syshax.xml) only if you compile with make cfw-coldboot. If you use make or make cfw you get the standard iosuhax with also region free

Yes, I see no reason for it to not work from sysNAND

 

[Speighty1]

Any luck on loading rednand after loading your fw.img.

 

[WexMajor]

I have a question. Now assuming someone follows all the right steps aforementioned in this guide... without bricking because of a mistake they made or anything like that... once This coldboothax installation is actually up and running successfully on the wiiu... Would there be a risk of bricking later further down the line??? I once failed to load fw.img using haxchi, the console would freeze after the wii u many logo appears, and eventually I discovered that it was because the SD card failed to mount... so I simply re-inserted it into the socket, and then it worked. Now assuming someone uses this: https://gbatemp.net/threads/haxchi-boot-fw-img-from-nand-no-sd-card-needed.449769/

would this mean that they are safe from such issues??? Can someone at least say that they're like 80-90% sure that this method is brick-safe?? (Assuming that you didn't commit a mistake during installation, and that you tested it successfully on your own console)

And P.S @::Phoenix:: Thank you for your efforts, this is excellent work.
