3. How to Update iPhone to an Unsigned IPSW

Usually, when Apple releases a new iOS update, they stop signing the old iOS firmware version within a week or two. This has always been Apple’s strategy. But this also creates a problem for the users sometimes.

So, if you are having an issue and you want to use an IPSW to update the version of your iOS that has already been unsigned by the company, then Futurestore is your best choice. Here are the steps;

  • Download the ‘futurestore.zip’ from the internet. Extract the file on your hard drive and copy the target iOS .shsh2 blob there. Then, copy the iOS .ipsw file in the folder.
  • Then, you can rename the ‘.shsh2’ file to ‘my.shsh2’. and the 11.0.3 .ipsw file to ‘restoreto.ipsw’ and iOS 11.2.6 .ipsw to ‘signed.ipsw’.
  • Open .shsh2 with notepad and find the generator key string. Then, type the string you found and enter it.
  • After that, connect the device to your Windows PC and make sure iTunes is not launched or not running in the background.

After that, launch the ‘Command Prompt’ and go to ‘C:\futurerestore\’. And then type the following command;

futurerestore -t my.shsh2 -isigned.ipsw restoreto.ipsw

If the file names aren’t changed, then it will look something like the following;

futurerestore -t 1234567890123_iPhone6,1_n51ap_11.0.3-15A432_a1bcdef234abc567d8e9f012345a6789b01234c5.shsh2 –i iPhone_4.0_64bit_11.0.3_15A432_Restore.ipsw iPhone_4.0_64bit_11.2.5_15D60_Restore.ipsw
