Hacking Haxchi-coldboot - autobooting Haxchi installer

[::Phoenix::]

sigpatcher2sysmenu isn't compatible with coldboothax
Use either cfw-coldboot branch of iosuhax or rednand

Exactly, if you want to use signpatcher you nee dthe one compiled for coldboot, not the one returning to sysmenu.

Ok I dusted off my wii u from this march. before I attempt this hachi stuff I got 2 questions:
1. I need access to the wiiu shop to buy a ds game yes?
2. Is the latest firmware exploitable? cause I hadn't bought a ds game yet.

Yes to both questions.

Truly, we've reached the Promised Land.

I've heard that if you have games on your HDD while using cold boot your Wii U will brick. Is this true?

You will brick if your DS VC game is on USB and not in sysNAND, but the installer will make sure that the game you select is in sysNAND. USB games are not shown in the list.

Nope, just the autobooted title needs to be in system memory.

 

[zeldaism]

Thanks for the response guys. It's time to use coldboot then.

 

[iAqua]

Yes, this is the start.

 

[socialbacon]

This is awesome, thank you! I assume coldboot is now considered "safe" to use? I don't think I'll use it until a simple uninstaller is available.

 

[ihaveahax]

just in case, but should quick start be enabled or not? does it make a difference?

I don't see why it should be a problem. In the worst case, just turn on the Wii U from its power button (not the gamepad one) and it will boot normally.

yeah......I forgot about that. I just generally start the console from the gamepad, so...

@::Phoenix:: now another issue. I tried installing coldboothax (5.5.1U), but it said "Default id is wrong. Coldboothax already installed? Exiting...", despite the fact I've never modified system.xml at all. do you know why this could happen?

It seems thet id of the system menu is different depending on the region of your console. My installer works on EU consoles only atm. I will update the installer.

I just have one question. Does this still include that thing where it'll boot up fw.img twice, having to go through the IOSUHAX logo two times before the home menu loads up? I'm waiting for the times when coldboot is seamless and works as quick as booting cfw manually.

The double loading is still there. I had to setup redNAND first, before experimenting with the issue and it took a lot to dump the nand. That's something I working on. Coldboothax has nothing to do with that issue, is an issues of fw.img and cfw_booter.
