In today's video, I have a quick tutorial in which I am going to show you how to downgrade from iOS 11.4 or iOS 12 Beta 1 down to iOS 11.3 Beta 6 which is essentially iOS 11.3 since the latest Beta is also the release build most of the times. iOS 11.3 and iOS 11.3.1 stopped being signed a very long time ago, this means that in theory, you should not be able to downgrade to them right now, but if you still wanna use the upcoming Electra Jailbreak, you still have a chance.
For some bizarre reason, Apple still signs the Beta 3 and Beta 6 of iOS 11.3 but they don't say that publicly. These betas don't show up in the Apple Developer Portal from which developers usually download these Betas. I am pretty sure Apple will close the signing window for the betas very soon once this becomes widespread so if you want to downgrade your device do it right now!
Unfortunately, there is no publicly available online tool I am aware of that can check the status of Beta signing so you will have to try and see if it restores. If right at the beginning the restore fails with an error in iTunes, Apple most likely patched it. If the restore starts and the progress bar increases on the phone, the signing window is still open and the restore proceeds.
