Yeah I know about the thread(I sometimes lurk without posting), I was just asking why he would do that without knowing fully what it entails, since it's normal to only have devmenu after installing dev firmware. After all if he followed the thread he wouldn't ask if he did something wrong. This guy had a problem with a 3ds after following a video guide, we tried to help but he went "lol I'll just delete everything and start over"
So it's not about why he installed it, more like why he did it without fully understanding it first
