A new program will help you restore to iOS 7 without losing the jailbreak

  I have talked to you repeatedly about SemiRestore, a program for Windows which will allow us to perform partial restores for iOS 7 without losing jailbreakthe one we have for devices. Practically, the program will delete all the data from iOS, leaving only the standard files in the terminal, this being equivalent, to a certain extent, to a real restore. The procedure allows performing this partial restore without actually reinstalling the operating system and without using SHSHs, so you can keep any version of iOS 7 si jailbreakthe related

  SemiRestore it is currently in the final stage of the development procedure and works with all versions iOS 7 who have already jailbroken. Unfortunately, the program does not work for terminals that do not have a jailbreak and does not allow a downgrade or upgrade for iOS 7, so do not think about such a thing because you will not be able to. SemiRestore will be launched in the very near future and it's only a short time away iOS 7.1, which blocks the jailbreak.
