As you all know, Apple released iOS 8.4.1 on Thursday and closed the possibility of jailbreak untethered with the tools available. The good news is that Cydia Saurik released Impactor, which allows to restore directly from your iPhone / iPod or iPad to keep us in a vulnerable version of the jailbreak and that Apple has long allowed a reasonable time to sign before leaving the previous version to avoid that, when you upgrade, we run a potentially serious failure.
While continue signing iOS 8.4, you can do the downgrade and therefore, we can do the jailbreak to our iPhone / iPod or iPad. The method is quite simple, you just need to get the .ipsw file before restoring. We have everything you need after the jump.
Tee tutorial below will guide you on how to download from iOS 8.4.1 to iOS 8.4:
Step 1: Go to ipsw.me page to see if Apple still signing iOS 8.4.
Step 2: Go to our download page and downloaded. To know exactly which model of iPhone / iPod or iPad have, it is best to check with the box.
Step 3: Connect your device to your computer.
Step 4: Deactivate Find My iPhone in Settings > iCloud.
Step5: Turn off Touch ID/Passcode from Settings > Touch ID & Passcode.
Step 6: Open iTunes and choose our device in the upper left.
Step 7: Click Alt (Shift on Windows) + click Restore.
Step 8: In the window that appears, choose the .ipsw file you downloaded in Step 2 and accept.
Now, wait until the device finishes restoring and install iOS 8.4.
The possibility exists that you leave not restore, but this is solved by forcing the DFU mode, guide provided here or you can follow the steps below:
Step 1: Turn off the iPhone / iPod or iPad.
Step 2: Connect the iPhone / iPod or iPad to your computer.
Step 3: Press the power button for 5 seconds.
Step 4: Without releasing the button, we press the start button and hold both for 10 seconds.

Step 6: Now we go to step 1 of the tutorial.
