▶ Fix iTunes errors and clean your iTunes with iMyFone TunesFix: https://goo.gl/4vSW6k In today's tutorial, I am going to show you how to save your SHSH2 blobs for iOS 11.3.1 and #iOS 11.4 with the custom nonces that Coolstar, the developer of #Electra has posted on Twitter for A10 and A11 devices. These devices are the iPhone 7, 7 Plus, iPhone 8, 8 Plus, and the iPhone X. If you have one of these devices and you want to downgrade in the future back to iOS 11.3.1 for Jailbreak, make sure you follow this tutorial and save your SHSH2 tickets while the signing window is still open. Apple will soon close the iOS 11.3.1 signing window, and after that, you won't be able to save your SHSH2 blobs for iOS 11.3.1 anymore. Without SHSH2 blobs, there is no way you can downgrade to #iOS 11.3.1 in the future. Saving is simple and requires just the ECID and the A number of the phone for proper identification of the device (GSM or Global variant). ▽ Resources ▽ ▶ Learn how to make iOS Apps!: https://goo.gl/NzPNU6 ▶ TSS Saver: https://tsssaver.1conan.com/ ▶ Coolstar Nonces: https://goo.gl/g3Pv3v ▶ Identify iPhone Model: https://ipsw.me/device-finder ▶ iOS Older iBOOT EXPLOIT UPDATE: It Allows Downgrades | It is Untethered (iOS 7 & lower): https://www.youtube.com/watch?v=voK5qe5Rab0 ▽ Social Media ▽ ▶ Our Sub-Reddit: https://www.reddit.com/r/idevicecentral/ ▶ Facebook: https://facebook.com/fce365official ▶ Twitter: https://twitter.com/FCE365 ▶ Our Website: https://fce365.info/ ▽ Full disclosure ▽ The link for iMyFone D-Port Pro from the top of the description is sponsored by iMyFone.
