THE INSTALLER IS COMPLETELY SAFE AND IT IS VERY UNLIKELY IT WILL BRICK YOUR WII U. IF YOU HAVE AN ISSUE, IT CAN PROBABLY BE SOLVED, JUST READ THE FAQs! This is a branch of Haxchi which includes an optional installation of coldboothax and a recovery mode if you mess things up. This means that after you select your game in which to install Haxchi, you can choose to let this game autoboot when turning on your Wii U. In order to trigger the installation, sd:/haxchi/coldboothax.install should be present in your sd. I already placed this file in the attached zip. Features: Safe coldboothax installation. If pushing L + R + dpad_down + A during boot the elf sd:/recovery.elf will be executed. This allows for recovering in case config.txt or something else was wrong. Coldboothax can be reinstalled over a previous installation safely. You should autoboot something which works with coldboothax: COLDBOOT-ENABLED sysNAND fw.img, i.e. made with make cfw-coldboot (dimok's fork) redNAND fw.img coldboot-enabled sign_patcher (not recommended until dimok officially releases it). the homebrew launcher (this is just to have an additional fallback plan if something goes wrong, but it is highly recommended to configure a button press for HBL) The provided config.txt is as follows: a=wiiu/apps/homebrew_launcher/homebrew_launcher.elf default=fw.img HOW TO UNINSTALL COLDBOOTHAX Use this https://github.com/marco-calautti/coldboothax-uninstaller/releases This is my branch on github: https://github.com/marco-calautti/haxchi/tree/haxchi-coldboot Grab the zip here: https://github.com/marco-calautti/haxchi/releases enjoy FAQs Q. My Wii U does not boot at all! A. Apart from very unlikely events, your Wii U is still booting Haxchi. Before doing anything stupid, remember that you can download the coldboothax-uninstaller. Rename coldboothax-uninstaller.elf to recovery.elf and put it in SD root. Then, when Haxchi boots push the combination L + R + dpad_down + A. The uninstaller should run, letting you to uninstall coldboothax. Q. I am getting a bootloop! A. You are likely using a sysnand fw.img not compiled for coldboothax or the non-coldboot signpatcher. Be sure your fw.img has been compiled from dimok's github with make cfw-coldboot or that you are using the coldboot signpatcher. Q. I get -5 when loading any homebrew with a button. A. You are using an older version of my Haxchi. Download the new installer, rename haxchi.elf to recovery.elf and put it in SD root. Then when Haxchi boots, push the combination L + R + dpad_down + A. You should be able to reinstall haxchi again and fix the issue.
