How to Downgrade to iOS 11.3 (B6) Without SHSH2 Blobs? (For Electra Jailbreak)

Update on June 22nd: Apple does not sign iOS 11.3 beta 5/6 any more.


This guide is  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. For some bizarre reason, Apple still signs the Beta 5 and Beta 6 of iOS 11.3 but they don't announce that publicly. These betas don't show up in the Apple Developer Portal from which developers usually download these Betas. 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.
