Earlier today, hacker Coolstar (one of the key figures behind the development of the next jailbreak for iOS 11.3.1) announced that he and his associates will assume the responsibility of solving the one remaining issue standing in the way of the aforementioned jailbreak’s release: a filesystem remount for iOS 11.3.x.
Coolstar / Electra Team Tackle Remount Fix
We (@electra_team) are working on fixing up Spark’s bypass ourselves now. Please lay off Morpheus as we are working on it ourselves now

Until today, @Morpheus______ was working on solving the filesystem remount issue – apparently, according to tweets from Coolstar (and even a few from Morpheus himself), the constant barrage of individuals spamming Morpheus for an ETA and the pressure were too much to bear.
Curiously it’s unclear whether Coolstar and associates will be forced to burn a previously undisclosed (0day) exploit in order to get the filesystem remount working, but it seems like all options are on the table and we’ll just have to wait to see what the group comes up with.
Will have to see if we can patch up some iOS kernels to test remounting more easily with the assistance of Corellium
As we might end up having to tackle the remount issue ourselves, and it would be nice if we could save our own 0day for iOS 12…

Remember: a 0day saved for iOS 12 can be backported to 11.3.1, but a 0day burned on 11.3.1 may not work on 12 as Apple will probably end up patching it even though it doesn’t really affect device security
Also super annoying apple signing window bullshit .-.

In closing the Electra team, which again is spearheaded by Coolstar, will need to come up with a solution for the final remount component before the jailbreak for iOS 11.3.1 is released; as usual, no ETA was given. Stay tuned for complete updates.
