Hi, I have a weird situation. When I tried to use PkgBackup, my IP5 (9.02, JB) froze, and I cannot do a shutdown by holding the sleep/wake button for 5 seconds. Searching online, it seems possible to use the sleep/wake button and the home button at the same time for a forced shutdown. My question is: what does this do, and will it affect my jailbreak? Thanks for any help.
