Hey, if i can recall right, there was 2 Coldboothax developed. 1 by @smealum and 1 by @Hykem As far as we now Hykem documented very much and wrote it down to Wiiubrew. Smealum released Iosuhax but there is not a exploit released. I searched on Google and looked up Wiiubrew but there are no signs giving away how Coldboothax works. I don't know if Team Salt is working on such a thing but im interested to know a bit more about this topic.
