New iphone 6 plus, about two weeks old. iMessage stopped working so i had to restore with the 8.4 ipsw and rejailbreak. I cant install anything in cydia.. Preferenceloader is missing and i cant find any fixes for this for 8.4 .. Ive tried reinstalling substrate, and ive tried both PP jailbreak and TAIG jailbreak. Also, getting timeouts when trying to add new repo sources. WTF??!! This has been a huge nightmare.
