Once Apple has released a new firmware, we get a period of about a week to downgrade back to the previous version. After that time, Apple stops signing the previous firmware, making it impossible to go back. The only time this window is extended is if there is the potential for a problem with the new iOS and they give users more time to go back – this is rare.
Once a firmware is no longer being signed, Apple will no longer provide the SHSH blobs for it and it is these blobs that make it possible to downgrade. A few years back, we had a tool called TinyUmbrella at our disposal to save the SHSH blobs. These blobs were then used for stitching together a pre-signed version of the relevant firmware files – these could be used over and again to downgrade to where Cydia could be installed.
The loophole that allowed SHSH blobs to be used for downgrading was closed some time ago but TinyUmbrella is still usable for saving your blobs. You might be wondering why to bother when they cant be used but there is a chance that, in the future, we will be able to use them for downgrading again and, if you don’t save them, you won’t have that chance.
What Can TinyUmbrella Do ?
Right now, Tiny Umbrella only has the option for saving shsh blobs and storing them and it is good practice to start doing this now and every time you upgrade your iPhone or iPad. The developers of the app have already hinted that there will be an update to bring the downgrade facilities back again. It has been updated regularly through the years with support for each successive iOS release so start using it today and be prepared for the future.
