Many jailbreak users have experienced disappearing tweaks and non functioning tweaks. This comes from the fact that Mobile Substrate has not been updated. Saurik has tweeted he was not given any opportunities to update mobile substrate for iOS 7 before the new jailbreak released. This only works for iPhone 5 and below. The A7 devices which include the iPhone 5S, iPad Air, and iPad Mini retina do not work with this update. A7 users will have to wait for MS update from Saurik.
Saurik was quoted on Redmondpie:
(This is horribly dangerous: MSHookFunction is not designed to be used on functions that might actively be running; this makes Substrate get injected into launchd while launchd is loading launch daemons… no one should install this; it doesn’t even solve the problem remotely correctly for anything but SpringBoard/backboardd, and will end up leaving you with Substrate having been randomly applied to different background processes.)
He was referring to the MS Reload Fix which I assume was the reinstall we showed you previously. So please use the new update moving forward. He has stated this new fix was 100% safe and what needed to be done to update mobile substrate. Saurik was also quoted saying:
This only works on evasi0n 1.0.1 because it relies on the feature I had evad3rs add so I could solve this problem “correctly”. In that light, it probably does work (it is not “dangerous” as I described the previous ones), but there is still little point in installing it because clearly a new build of Substrate would come out soon using this new feature I got from evad3rs ;P. (Which didn’t happen yet as I took Christmas Eve/Day mostly as a holiday.)
