Derootifier does not work AT ALL unlike IGG that can live or inject itself, I did reinstall it though from Sileo even though my version was good and it probably wiped a bug and Legend of Slime loaded, LIAPP still prevented me from playing but I got the menu and this message :
IMGUR
So please accept my apologies for the confusion and the hassle. This was partly my fault for not being able to load and know that it was outdated from one version apparently? Last was a week ago so I thought it was me. But actually it was a day later than the last update there.
And yes for Derootifier I did install everything needed AND updated them too, nothing, it does not even detect a package manager, IGG seems to work well but it seems buggy at times. I dont know maybe I install bad tweaks? I tried an iap cracker from yours and another old one but I did remove them though so am clueless.
