Prepare for iOS 8.3 Downgrade SHSH blobs TinyUmbrella

When Apple closes the firmware signing window for iOS 8.3, users wishing to downgrade (or upgrade) to iOS 8.3 won’t be allowed to do so. Instead, you’ll have to settle for whatever firmware Apple is signing, which is usually the latest and greatest out there.

When that happens, it’s quite probable that it could spell the end of jailbreaking for a while—remember we just got out of a significant lull.

With this in mind, the ability to downgrade back to iOS 8.3 is very desirous for would-be jailbreakers. While there is no confirmed downgrade ability just yet, there are some things that you can do to ensure that you have the best chance to downgrade should that ability arrive.

This is accomplished by saving your iOS 8.3 SHSH blobs.

To save your SHSH blobs and prepare for a possible iOS 8.3 downgrade, you’ll need to use TinyUmbrella to do so. I’ll show you how in this post and video.

Step 1: Download TinyUmbrella from our downloads page

Step 2: Run TinyUmbrella

Step 3: Connect your iOS device (it doesn’t have to be jailbroken!)

Step 4: Wait as TinyUmbrella fetches and saves your 8.3 blobs

TinyUmbrella saves your SHSH blobs into a single file. To find that file, you’ll need to go to the following locations:

Mac: ~/.tu/.shsh

Windows: C:\Users\~\.tu\.shsh\

You can leave those files in place, but I advise you also to back them up on something like Dropbox. Again, these files have no real use at the moment, but they can be key assets if and when a downgrade arises in the future. From the rumblings I’ve heard, the possibility of that is very real.

But you better act fast, as once Apple stops signing iOS 8.3 it will be too late to retrieve your iOS 8.3 blobs.

What do you think about saving your SHSH blobs? Do you think it’s a waste of time, or are you optimistic about future iOS downgrading?

    You mentioned “upgrading” in your first sentence. Is it possible to save 8.3 SHSH blobs while still running 8.1?

    • JaeM1llz

      Yes, you can save SHSH blobs for the currently signed firmware regardless of what firmware you are currently running.

        just wanna clarify because i’m still on 8.1.2 JB until now and if ever 8.4 is not jailbreakable for a few more days and i decided to upgrade on 8.3 and apple is not signing it the method will be. upgrade from 8.1.2 to 8.4 then downgrade to 8.3 using my backup shsh blobs? i’m kinda confused because the last time that i did a downgrade it was 3gs&4 days 🙂

    My ios 8.3 is jailbroken now, i don’t want to restore and do all the stuff again. But I’m also afraid of loosing my jailbreak again 🙁

    • Hi

      If you restore RIGHT NOW you won’t loose your jailbreak (I think)

  • Ali

    Doesn’t detect my iPhone 6. Fresh restore, and set up with iTunes as new phone.

  • Chrshdkim

    what sound is that when you plugged your phone into the dock?

    • Kyle Warwick-Mathieu

      thats the Windows 8 USB connected sound

    Didn’t we go through this a few months ago and I remember saying this say comment as well. Downgrade is dead. SHSH is pointless. I know people who have had that shit saved since iOS 6, and it’s just sitting on their desktop while they went to an iPhone 6 plus. That hope of downgrading is dead as the walking.

  • Sir.Rhommi

    Does anyone know the name of the tweak that lets you download your list of tweaks so you’ll have it if you lose your jailbreak?

    Do you need to be on 8.3 to save an 8.3 blob?

    • Chris

      Yes.

  • Hot12345

    Can it be also if you don’t jailbreak OR jailbreak your Phone to save SHSH blobs? And how can you downgrade back to ios 8.3 then?

    • Chris

      Yes, you can get the SHSH blobs on both non-jailbroken and jailbroken devices, at this point we can’t do anything with them but in the very near future we should be able to use them.
