I am having an issue with this right now and any guidance would be appreciated. I have manual installed ios 8.1 through itunes, once the phone restarts I kill itunes so that it never connects with teh phone, I then run the pangu jailbreak (phone still does not show there is a software update), once phone reboots I let itunes open and choose to restore from a backup I made a few days ago. At this point the software update available pops up as the phone starts to restore the backup and the settings on my phoen has the badge that it is available. Is there another order I should be doing things to get completely through the process with no update badge on the phone?
