Iphone 4 IOS 6 Mobile Substrate not functioning

I just Jail broke my Iphone 4 after 2-3 weeks of use and It was working fine and dan.until I accidentally shut it off. This happens to be a tethered (or semi, whatever they call it) Jail break. When I just booted it on the computer it was fine. Until I tried to use any of the Cydia apps. I opened up activator (one of the featured apps) and it said something about mobile substrate not working, and that the device was on safe mode. I couldnt deactivate Safe mode and none of the Cydia apps work. Please help! I have tried Just booting it and even reinstalling the jail break but none works. What do i do!

Go to Cydia\Manage\Settings
Click on Developer. Reload Cydia
Fixes everything. This worked for me. I had the same problem

  • Will I ever find love? (16 w/High Functioning Autism)? I don't want to post this as a long question… I copied it to my Notes, and took 5 iPhone screenshots of it that you all can read.

  • Why is my iphone 4 (not an IOS) not connecting to my itunes 10.6? I've downloaded the latest version of itunes 5 times and every single time it says "the iphone can't be used because it requires iTunes version 10.5 or later". What to do? What to do?
  • When will the mobile substrate for ios 7 jailbreak be updated? I jailbroke my iphone 5c on ios 7.0.4. And nothing is really working. None of the cydia stuff is functioning. I looked up why and it is because the mobile substrate is in need of an update. I just want to know when it will be updated?

I recently bought a factory jailbroken (can be updated) Iphone 3gs, and later the new software iOS 6 came out so i updated it.ever since i updated it i can no longer send MMS messages.before the update everything worked just fine.
