iMore does a great summary of how the latest iOS update might trip up some folks. Have a read here
I’ve done two devices now – my iPhone5 froze two thirds of the way through, and needed to be hard reset; my iPad mini went fine, althought the screen went blank and the little progress bar also didn’t move, both for what appeared ages (hint – don’t watch – have a cuppa instead)
The article misses an important step that I’ve instituted as a regular practice for each and every update, after getting stung with an update that wiped my iPhone and I hadn’t backed up recently. Oops. Never again:-
1. Connect device to itunes – sync with backup – disconnect
2. Repeat (1). Thus there are now two backups on your computer as, well, backups.
3. Start the update process as normal (meanwhile I learnt something here – adding a new step zero – hard reset before starting everything)
And then finally, do a hard reset again once the device is fully updated. Job done. Back to work. Sigh. Check facebook instead.
So to summarize the update iOS process:- Hard Reset. Backup. Twice. Update. Hard Reset.
Don’t know how to do what I call a hard reset? Push home and power button until it turns off, KEEP HOLDING until Apple appears.
Check out this wiki, but be aware that what they call a “soft reset” is what I call a “hard reset” whilst what they call “hard reset” I call a “wipe and restore” which is higher up the Richter Scale of resets. Sorry if the phraseology is confusing, but knowing these procedures (call them what you like) is very useful.
It is recommended to carry out a soft reset when your phone starts presenting peculiar behaviour, as this clears the phone’s memory and can solve many minor problems. Some people recommend a soft reset regularly (Ed: I do, weekly 😉 Some poorly written apps or ones that crashed can leave things in the phone’s memory, and this action clears them out. Powering off the iPhone is similar to the soft reset but not quite as effective in clearing out the phone’s memory (yup, hard reset is better)
