What is EtasonJB?
EtasonJB is an untethered jailbreak for all 32-bit devices (except Apple TV),running iOS 8.4.1 that includes iPhone 4S, iPhone 5, iPhone 5C, iPad 2, iPad 3, iPad 4, iPad Mini, and iPod Touch 5. The jailbreak app can be installed using Sideloadly, AltStore doesn't support iOS 8.
Once installed, the EtasonJB app will be available from the Home Screen. To jailbreak the device open the app and tap on the blue Etason JB button. The app will exploit the iOS allowing read and write functions to the kernel and will install Cydia as the default package manager.
With the Cydia app, you can add new repositories and install tweaks that will add some freshness to the older device. iOS 8 without jailbreak is pretty much useless. It also installs an untether for iOS 8. It means that your device even after restart will be still jailbroken. There is no need to re-jailbreak your device each time you will forget to charge your iPhone.
Etason untether is an untether package for 32-bit devices running iOS 8.4.1. It was created by @tihmstar, the same developer behind EtasonJB. The untether exploits the Pegasus jsc bug and bootstraps Etason jailbreak. EtasonJB installs this package by default in the background.
Be aware, that if you downgraded from iOS 9.3.5 to iOS 8.4.1 it's required to perform a full erase before using etasonjb, otherwise Cydia app will not show up. The latest release of EtasonJB Jailbreak RC5 was published in 2017. Etason untether package was updated in 2021.
