Save jailbroken apps before updating
However, if you are an advanced user and are using i OS 8 with jailbreak access, the i OS 9 update won’t be available to you.
So are you Suggesting that I add a “stop” button with exit shortcut? If you mean the open url at the end of the menu on apps how will that work?
Note: Please turn off the pass-code lock and Find my i Phone from the settings before you proceed with restore.
The phone will automatically download the new flashable software from the online source and you will be able to see the progress in i Tunes.
The phone will reboot and complete the flashing process in recovery.
After the phone reboots, it will give be as good as new.
