Dang...didn't work. I see all the iosgods options in the settings screen - and I turned them all on - but the app still crashes on boot. I'm on an iphone 6 plus with the new 9.3.3 jailbreak - and to be fair - I can confirm that the crashes are not a result of this tweak: If I load the phone without the jailbreak active, the ufc app will load just fine.
If I boot into jailbroken mode however, the app will crash regardless of what I have installed or uninstalled. Meaning I don't have flex installed nor do I have that TSprotector thing that people have mentioned. It crashes regardless - anyone come up with a solution for the crashes in general?
EDIT: SOLVED
The issue was with the jailbreak. I chose to do the version that bypassed the computer altogether. Obviously it was faulty. I re-did the process with the official pangu one - and everything is working great.
Thank you!
