ISFShax exploits boot1 using a specially designed ISFS (SLC filesystem) superblock. Once installed, it offers similar capabilities to de_Fuse. Since it runs before IOSU, it can apply early patches to IOSU and repair most types of bricks. However, it cannot protect against bricks caused by boot1 corruption, seeprom issues, or installing a faulty ISFShax superblock. Additionally, ISFShax cannot help if the Wii U is already bricked.
Features
- Rebuilding or upgrading the MLC
- Removing the 64GB MLC limit and disabling SCFM
- Brick protection, such as before performing a region change
- Cold booting redNAND, which is helpful when the eMMC is failing
- Providing a minimal CFW that can launch old homebrew using the homebrew launcher (though this might be less useful with Aroma and Tiramisu available)
- Preventing the Wii U from turning on the GamePad during boot using a stroopwafel plugin

To protect against Nintendo pushing a boot1 update, which would (probably) brick a console with ISFShax, boot1 updates are blocked by the 5isfshax.ipx plugin. Other titles from a system update should still install normally. |
Follow this guide to install ISFShax.
