hi everyone Aaron here for zollotech and i wanted to show you how to downgrade from ios 16 to ios
15 properly without losing any data i'll show you step by step how to do that whether you're
using an ios 16 beta or maybe ios 16 has been released and you want to go down to a previous
version you'll be able to do that as long as apple is signing the current versions of ios
sometimes apple stops signing them and you'll no longer be able to downgrade
to them but for now we'll be able to downgrade to ios 15 or any subsequent version of ios 16
and the first thing you'll need is a mac or windows computer and you'll need a mac running
the latest version of mac os or a windows computer running the latest version of itunes you'll also
need an apple id and password so you'll need that once we restore the phone to put that back in to
activate the phone or unlock it also a quick word of warning if you're running watch os 9
and you downgrade to ios 15 typically you'll lose connectivity completely to the device so
you want to make sure that you are aware of this and also you can't easily downgrade watch os
9 to watch os 8 without bringing it to apple to have them do that so keep that in mind
if you do have watch os 9 you probably want to stay on ios 16. also make sure you have a backup
as when we restore this it will completely wipe everything off the device so just keep that in
mind and the first thing is if you're using icloud it's pretty simple because everything
just syncs so if you go into settings tap on your name at the top then tap on icloud
depending on what you have turned on it will just sync to the new phone anyway once it's restored or
maybe if you're moving to a different phone so you'll see i have photos turned on icloud drive
icloud mail all my passwords in keychain under show all you can see here all my notes messages
health data contacts calendars reminders safari news stocks home fitness wallet game center and
siri as well as different apps all of that data is saved to icloud if you have this turned on so this
is really simple and easy and you can verify some of this data such as photos on icloud.com so if
you want to make sure it's already backed up there make sure you have all of these turned on or you
create a backup first so if we go back one page go down to icloud backup you'll see it's turned on
make sure you make a backup now or have one before but all of your messages as long as they're turned
on in icloud settings all of those will sync anyway but just make sure you have a backup i
typically recommend making a backup of the current version anyway if you want to bump back up to ios
16 later you'll have this backup to pick from now in order to restore this to ios 15 you can't just
simply plug it in and hit restore in itunes or in the finder on a mac what you'll actually need to
do is put this into recovery mode because you need to download the last version so unless you have an
ipsw file which is the full install file for the iphone you'll need to put it into recovery mode
and it's pretty simple to do that so first what we want to do is take our lightning cable and plug
it into our computer and then plug it into our iphone you'll see it's connected it's charging
and it's asking me if i want to trust the computer tap on trust put in your password or passcode and
then we can move on now you'll see in finder just scroll down on the left here it shows my
iphone and then we need to click trust once we've clicked trust we should be good to go and then it
will connect next time when we need it to now also keep in mind if this is on an itunes on a windows
computer it will also be on the left here as well now you'll see we can click on restore iphone but
this won't work because we don't currently have ios 16 easily available to download through this
so we need to have it in restore mode now in order to put our phone into recovery mode so
we can restore it press volume up volume down press and hold the power sleep wake button
so i'll do this in real time so up down press and hold and then keep holding until it reboots
and then continue to hold until you get to the restore options so you'll see here it's still
saying slide to power off it's rebooting i'm still holding with my finger we'll wait just a moment
and it will reboot into the recovery mode options so we'll wait just a moment here
it's still rebooting i'm still holding with the power sleep wake button still holding it down
and now you'll see a computer with a lightning cable on the computer itself on my mac here you'll
see it says there's a problem with the iphone iphone that requires it to be updated or restored
and now we can just click on restore however if we made a mistake and we want to reboot we don't want
to continue and restore everything we can do that by unplugging our iphone and repeating those same
steps volume up volume down press and hold the power sleep wake button and it will go back into
the normal boot mode so i'll show you this again in real time i'm still pressing and
holding on the power sleep wake button once it reboots and we see the apple we can let go
so now if we want to restore it we'll go back and repeat those same steps volume up volume
down press and hold after we've plugged in the lightning cable the lightning cable is what makes
the difference here so again wait until your computer recognizes it so volume up volume down
press and hold the power sleep wake button until it reboots and shows you the recovery mode again
now that it's showing the recovery mode we go over to our mac or our computer and then just
simply click on restore it'll take just a moment you'll see here we have the option to restore
but it will take a moment pop up on the screen are you sure you want to restore the iphone
we'll click on restore and update give it just a moment here and now it will ask us to install
the latest version that's available of ios 15. so in this case 15.5 it could be 15.6 or 15.7
go ahead and click on next then click on agree it will take a little while and this depends
on your internet connection you'll see here this is a pretty large file at 6.55 gigabytes
and it will take about 18 minutes or so to download depending on your internet connection
this could be faster or slower now the iphone has been restored it's taking about eight minutes or
so to fully restore it and then it has to boot again where you'll have a little progress bar here
so it could take anywhere from eight to twelve minutes or so it depends on your computer after
you've downloaded the actual restore image file so this can take a little bit of time and we'll
come back when it's done now the iphone has been restored and it says that it's locked to owner so
we can unplug the cable and then swipe up and if you have a different phone nearby you can
quickly set it up that way or we'll just set it up manually here where we'll tap on our language
select your language select your country and then go into setup manually or bring a different device
that you already have near it whether that be an ipad an iphone or something else we'll set it up
manually for this demonstration and then we'll connect it to a network once you're connected to
a network tap on next and wait for the next step now again it's going to say that it's locked to
owner so we'll need to put in our username and password for icloud so go ahead and do that as
long as you put in the correct username and password it will go to the next screen where
it says data and privacy tap on continue now this is where you'll set up face id or touch id
so we'll do that and now face id is set up tap on continue and now you can create a passcode
once you're past the passcode setup now we have the option to restore from an icloud backup
mac or pc transfer directly from another iphone move from android or don't transfer
and just set it up as a new device in this case we'll restore from an icloud backup so we'll
do that we'll have to put in our icloud id and password again then we'll have to agree to terms
and it will take a moment to set this up and it will look for your backup now as you can see our
different backups here and in this case i actually can pick the one i made while i was on ios 16. so
just tap on that one and we'll go to the next screen where we can make this your new phone
just tap continue then keep it up to date just tap continue you don't have another option and
now it will restore from icloud this can take quite some time depending on your internet
connection and more so it'll say estimated here it could say anywhere from five minutes to
two hours it just depends on your internet connection give it some time and then come
back when it's finished now it took just under 13 minutes for it to fully restore again this depends
highly on your internet connection so now we're at the main screen it's going to take a moment
for everything to start up again and it will start installing all of your different apps so all of
the things that were synced across icloud whether that be messages or mail or music will start to be
brought back to the iphone now that it's restored all of your apps you had before the same layout
you had on your home screen and everything else so you can see all of the different apps here
they're sort of grayed out and we're waiting for them to install so this will take a little
while again depending on your internet connection which phone it is depending on its speed overall
and more so as you can see it's restoring everything now and now you're back to ios 15. if
you go into your settings go to general and about you can see that we're on the latest version of
ios that's available so if this is ios 15.6 or 15.7 if that ever comes out or by the time you're
watching this video you could even use this method to roll back to ios 16 versions and so that's how
you restore everything all of your different history contacts and more will all be brought
back from the backup and then everything will sync from icloud back to your messages and more and so
everything's syncing right now will take a while and it will process everything in the background
