As many as you know, SHSH blobs are an important part of the jailbreaking community. What is not known by many is that Cydia automajically saves them for you, even if you haven't upgrade to said version yet. Here I will write a tutorial on how to check what blobs you have saved, and how to export them off Cydia to your computer.
Identify what shsh blobs Cydia has saved
The content I've highlighted in the picture below will tell you what shsh blobs Cydia has for your device.
Now that you know what you have saved, let's get started.
Save shsh blobs to your device
1. Search Cydia for "iSHSHit" - download and install
2. Open the application through icon on your home screen
3. Select what device your on under "Model" (may be automatically set)
4. Select "Via Cydia"
5. Select "Firmware" to choose what blobs to save, I advise you save them one by one (There is sometimes an error with when selecting "All Versions")
Export shsh blobs from device to computer
(I advise you to create a folder on your desktop dedicated to your shsh blobs)
1. In iSHSHit press "Manage SHSH"
2. You will see the list of shsh blobs that are saved
3. When you select one, you'll be brought to the Email application
All you need to do now is Email them to yourself and put them in your shsh blobs folder for safe keeping!
It was amazing apps to recognize through blobs cydia.
I may be missing something. I have a 4s on 5.1.1 (factory unloacked) jb with Absinthe 2.0.4. When I open Cydia, at the top instead of SSh info, it says this devise is in the pending TSS queue. What does that mean. I installed "iSHSHit" anyway but it says the requested firmware is no longer available for signing. Thanks in advance for help/explanation.
Re exporting the blobs to computer..if I email the content directly to my id, then what is the use of connecting device with the pc?? I think I can still get the content through my inbox directly to my pc..or am I missing something here..???
Could I save the blob file from another device say my Verizon iphone 4 than turn around and use those files to restore my sprint Iphone 4s running 6.0 back to 5.1.1? Just trying anything I need to downgrade it so I can flash it to Page plus or unlock the Sim
If you forgot to send an email what will happen?
i have iphone 4s which was on ios 5.0.1 jailbroken, i updated it to ios6 (my mistake) can i downgrade it to ios 5.x.x?
Sadly, No we are both out of luck until the new Jailbreak is released. I don't think it will be anytime soon either..
