How to Jailbreak iOS 8.4.1 with EtasonJB [Fully Untethered]

EtasonJB is finally out! Tihmstar has finally released his untethered iOS 8.4.1 jailbreak to the public. Here’s how you can download and use it on your iPhone, iPad, and iPod touch.

  • Update – DO NOT install AppSync Unified after using this tool.

What is EtasonJB? 

EtasonJB is a fully untethered jailbreak developed for 32-bit devices running iOS 8.4.1 firmware. It is developed by eminent hacker Tihmstar.

Several other developers such as Siguza, Jonathan Seals, and jk9357 have also worked on this tool.

iOS 8.4.1 jailbreak untethered

It works exactly like the Phoenixpwn jailbreak for iOS 9.3.5 firmware. It is based on the Trident vulnerability present in iOS 9 and 8 firmware versions.

EtasonJB may seem useless to some but it’s very important for legacy devices, here’s why –

  • Firstly, the performance of 32-bit devices ion iOS 9.3.5 is quite unsatisfactory.
  • Secondly, since we can go back to iOS 8.4.1 by firmware spoofing, it makes this jailbreak even more important.

At present, the RC2 (Release Candidate 2) version is available for download, which fixes patcyh. You can expect more fixes in the upcoming versions, hopefully.

Here’s the complete list of devices that are compatible with this tool.

How to Jailbreak iOS 8.4.1 on iPhone, iPad, and iPod

Step 1 Download the EtasonJB jailbreak IPA file using the direct download link given above. I suggest saving it right to your desktop for quick access.

Step 2 Download Cydia Impactor from this link. We will be using this utility to install this IPA file on our iOS device. Once you have downloaded it, launch it from your computer. 

Step 3 Connect your device to your computer. Cydia Impactor will now recognize it instantly.

Step 4 Drag and drop the etasonJB-RC2.ipa file to Cydia Impactor’s window.

Step 5 Cydia Impactor will now prompt you to enter your Apple ID credentials. Go ahead and enter your email ID and password.

Step 6 Once that’s done, Impactor will now commence the IPA sideloading process. This will take a minute or two. Once it displays “Complete”, you can safely disconnect your device from your computer.

Step 7 Unlock your device and the jailbreak application will now be present on your home screen. Open it and tap Trust when you get the “Untrusted Developer Certificate” alert.

Step 8 Press the Etason JB! button to start the actual jailbreak process.

Step 9 Wait for it to install the exploit and perform the necessary patches. Finally, it will install Cydia along with the untether. You can keep checking the progress in the top section of the app.

Step 10 EtasonJB will restart the Springboard and your device will be running a fully untethered jailbreak. You can now open Cydia and start installing your favorite tweaks.

Here’s a step by step video tutorial.

That’s all there’s to it! Time to open and dust off your old device. If you have an old 32-bit device lying around somewhere, this is the best way to jailbreak it.

As always, don’t forget to post your doubts or errors in the comments section below.
