Help disabling freecore on freedom

[PlsHelpMe]

Hi, I posted this on xda developers' website but they didn't take it too well so I'm hoping you guys could help me? I'll just copy my post from xda developersI was trying to get freedom to work on into the dead, so I followed a tutorial on YouTube which told me to add a hashtag on the second line of my hosts file but I still got the 'error no connection' notification. Then I tried enabling freecore, and it still didn't work. So I downloaded this installer 'Google Play Store 4.0.26 + Installer Cracked 1.1.2 Mod By Chelpus'. After that I was able to get the free in-app purchases, but now whenever I try to disable freecore it says 'freecore isn't available on your system' and the checkbox remains ticked. I don't know what freecore is so I'm not sure if I should just reinstall freedom. Can someone help me? I also have adaway installed if it's relevant. Thanks in advance!
