**Please make sure you properly understand all the risks involved before attempting to install it!**
Ensure you have an SLC backup at hand and a safe way to restore it before proceeding.
Thanks to shinyquagsire123's de_Fuse vulnerability it should now be possible to restore SLC without the need for an SLC hardmod, which should make repairs at least somewhat less troublesome.

isfshax is a coldboot boot1 exploit for the Wii U.
This repository contains the main isfshax exploit and stage2loader. It will use [minute_minute](https://github.com/shinyquagsire23/minute_minute) as a stage2
It will produce an (unencrypted) ISFS superblock image, meant to be installed through isfshax_installer or other means.
It will produce an (unencrypted) ISFS superblock image, meant to be installed through isfshax_installer.
The minute_minute stage2 payload will attempt to load (in order):
- `slc:/sys/hax/fw.img`
- `sd:/fw.img`
- `sd:/fw.img` (5 times)
- `slc:/sys/title/00050010/1000400a/code/fw.img` + patches
The first two locations are supposed to hold the full [minute](https://github.com/jan-hofmeier/minute_minute/). The third location is the OSv10 IOSU as a fallback. A minimal set of paches will be applied to the IOSU to make it boot with ISFShax and mitigate side effects of ISFShax and to block system updates.
In case a broken fw.img gets installed to the slc, the SLC load can be skipped completely by spamming the power buttion. In that case only the SD will be tried and it will be retried indefinitely.
When using minute with [stroopwafel](https://github.com/jan-hofmeier/stroopwafel) the [wafel_isfshax_patch](https://github.com/isfshax/wafel_isfshax_patch) is required or else IOSU would crash because of ISFShax.
