@Shahd Thanks for your insightful advices. I would add some things to do before proceeding with your steps:
1. Take the blood of a virgin (no need to kill her, a drop or two will do)
2. Before upgrading, hold your iPhone facing North. If this can be done at night and you can see North Star, even better.
3. In the back of your iPhone, make a pentagram using the blood
4. Cut a lock of your own hair and burn it so the smoke touches the iPhone and, very important, the pentagram. If you are bald… well, I wish you luck, you are f*cked…
5. Recite the two first verses of the Sauptika-parva in the Mahābhārata, in the original Sanskrit language it was wrote.
6. Pray two Christian Lord's Prayers, but backwards, phonetically. BEWARE: do it only TWICE, if you do it a third time, Satan will appear and bring you to hҼll. Well, to another hҼll not related to iPhone updating, actually…
7. You are done: now you can proceed with install, following your steps.
Now seriously, is Apple really being serious about this? Do we really need to perform black magic trickery so the iPhone performs as it should by just installing an update? Do we have to deactivate half the functions that make it a smartphone, in a way that the phone has the same functionality that a Nokia 6100? Come on…… 😐😠
Saluditos,
Ferrán.
