Jailbreak iOS 8.1 was updated last week, version 1.1 of the program Pangu8 being released by the hackers of the team of the same name, it still generates errors during the procedure of exploiting our terminals. Pangu generally generates the error at step 4, but the problem can occur at any stage of the process and so far the only method to solve everything involves a clean restore made for our terminals using Apple's iTunes program.
Performing an OTA Update to iOS 8.1, or any other version of iOS 8, is the main problem in this situation, the Pangu program is not designed to work 100% correctly in the situation where you used this method of installing the operating system. If you're going to backup your data, you're going to do a restore and then put that data back in via iTunes or iCloud, then you will be able to jailbreak without problems, at least in theory, but if you do jailbreak and access Cydia before restoring a backup then you will need to reinstall Cydia Installer.
