How to Save SHSH Blobs iOS 8.3 with TinyUmbrella [Instruction]
The fast release of iOS 8.4 can make Apple stop supporting the previous iOS 8.3 firmware soon. You still have time to save SHSH blobs iOS 8.3 with TinyUmbrella in case you wish to be able to possibly downgrade and re-jailbreak this firmware in the future.
You know that even the launch of iOS 8.4 makes all the current 8 firmwares jailbreakable thanks to TaiG and PP Jailbreak utilities. Once Apple stops signing 8.3 mobile operating system version you won’t be able to downgrade 8.4 to 8.3 [in case you need or want it to happen] unless you have SHSH blobs saved.
SHSH blobs come useful when the Cupertino-based giant stops signing older versions of mobile operating systems for iPhone and other iDevices. Once this happens the company stops providing SHSH blobs for the firmware it no longer signs and this is why it could be advantageous to have your own 8.3 blobs saved with TinyUmbrella which supports this.
