TinyUmbrella

TinyUmbrella is a name well known by jailbreakers. It is a tool that we used to be able to use to downgrade your iOS devices to a firmware version that could be jailbroken, very useful when Apple is constantly pushing out updates and patching up jailbreaks. At this moment in time, the tool is not fully working because Apple has patched the loophole that made it possible to downgrade. However, the developers say that, in the future, it will all work again and we will be able to go back to using TinyUmbrella for its true purpose.

TinyUmbrella works by saving the SHSH blobs on your iOS device for each firmware that Apple is still signing. These SHSH blobs would then be turned into an IPSW file that has been pre-signed and this file could then be used like all other IPSW files for the purposes of downgrading. The only difference is, with the TinyUmbrella IPSW, you can use it as often as you want because it has been signed.

While we can’t use TinyUmbrella [ext link] to downgrade we can still get into the habit of saving your SHSH blobs. At some time in the future, we will be able to use them to downgrade again so make sure you save them every time you update the firmware on your iOS device.

Save SHSH Blobs with TinyUmbrella :

  1. Using the given links, Download TinyUmbrella [ext link] onto your Mac or Windows PC and then install it tinyumbrella-ios-8-download-1-640x244
  2. If you are not running Java on your computer, you must download it, using this[ link ], because TinyUmbrella will not work without it
  3. Open TinyUmbrella
  4. Connect your iPhone or iPad to your computer
  5. Wait for TinyUmbrella to detect it and, once it has the valid SHSH blobs will be automatically downloaded and saved for you. Whenever you update your firmware in the future, plug your device in and run TinyUmbrella again to make sure the latest SHSH blobs are saved. tinyumbrella-ios-8-download-0-640x244
  • As we mentioned earlier, TinyUmbrella can only save SHSH blobs if Apple is still signing the firmware. Every time you save the bobs, they will be placed into a file named ~/.tu/.shsh. and a list of all known devices will be recorded in a folder called ~/.tu/.known_devices.

Saving your SHSH blobs regularly is a good habit to get into. As soon as we have word that TinyUmbrella can be used to downgrade your iOS firmware, we’ll let you know. In the meantime, follow us on Facebook and Subscribe to our free email newsletter.
