Spoiler: How to Install beta via OTA/IPSW [Guide]

How to install beta via OTA?

1. Enable Beta Updates (Settings>General>Software Updates>Beta Updates)
2. Check and sign into the right Apple ID to access beta
3. Select which beta you would like to receive (Public/Developer)
4. Hit "Back" and pull down to refresh
5. Do an encrypted backup or iCloud backup before installing the beta from release build
6. Install the beta

If you no longer wish to receive beta updates:

1. Turn off the Beta Updates (you can also sign out of your Apple ID to unlink your developer account)
2. Wait for the next public release or follow the guide below to install the IPSW release build

Troubleshoot: Sometimes, the beta update will not show so you may need to enable/disable Airplane Mode or restart your device before rechecking for update.

How to install beta via IPSW on Mac?

1. You will need to install either Xcode beta or MobileDevice.pkg which can be extracted from the Xcode beta (tap with two finger or right click to Show Package Content>Contents>Resources>Packages>MobileDevice.pkg - this will work on older Macs that do not support the latest macOS or Xcode beta)
2. Do an encrypted backup in Finder in case you need to restore your device
3. Hold down Option + Check for Update and select the appropriate IPSW file for your device (whether you're updating to a newer/beta firmware, reinstalling the same firmware or downgrading to previous firmware while retaining all your data) downloaded from Apple using your free developer account. Note: You must have an active internet connection as it will check the IPSW signing status before it will proceed with the update.
4. Enter your iPhone passcode once prompted to proceed.

Notes/Tips:

• Always keep a backup in case you need to restore your data if you restore your device
• It may be better to close all apps before installing the updates and/or turn off your device for about a minute or restart a few minutes after your device is updated
• You can also manually select the IPSW if you are restoring your device using Option + Restore iPhone. Restore will wipe all your personal data which you will need to restore your backup either using iCloud backup or Finder/iTunes backup
• You do not need to install the MobileDevice.pkg from each Xcode beta version unless Finder does not recognize the new iOS beta
• There is no MobileDevice.pkg equivalent to iTunes for PC which would require a new iTunes to support new/beta iOS
• If you receive a new iPhone, you can connect to Mac to update or restore your device to the latest iOS before setting up your device.
• You can also use the Recovery Mode/DFU to update or restore your device by manually selecting IPSW

Just in time!

"This update provides important bug fixes and addresses a rare issue where photos that experienced database corruption could reappear in the Photos library even if they were deleted."

 

[Banglazed]

IPSW is up

 

[tosbsas]

lets see if their are still pictures appearing on sold devices 😩😩

 

[s2mike]

Unsurprisingly, the issue affecting the quality of audio recordings sent through the Messages app is still present… hopefully that gets sorted out with 17.6

 

[James6s]

Just updated. I didn’t have any deleted old photos popping up but my 15 Pro feels even snappier… 😃🤣

 

[mikiotty]

Gonna wait a few days to see how the battery goes. 17.5 is really good and I don’t want it to get worse

 

[jpsmith76]

From 21F79 to 21F90 is quite the bump in builds for such a short period of time since 17.5 release.

 

[Sharkoneau]

Phone is hot (plugged in) and performing horrendously immediately after this update. Frame rate drops galore for every animation.

Probably the worst post-update performance in some time, though I wonder how intensive any Photos-related background processes are. Will continue to monitor.

Edit: Not hugely surprised, but the situation seems to be improving!

Somehow I think this is for the photos only as they were getting increasing notoriety.

With the number of builds in the release, maybe some other items got fixed. 🤞

Oh yeah, I figured this was solely to patch the photo bug. Just figured I’d share the info in case anyone visited this thread with the hope that maybe the audio bug was also fixed.

 

[cigz]

This is the first time I have ever received that kind of a notification for a update that was just released, at least on iOS 17. I was surprised when I saw it because I have automatic updates disabled.
They know they screwed up with the photos app bug.

 

[Populus]

I was thinking the same thing

Previously-deleted builds have accidentally resurfaced 😁

You gotta remember that code builds are in the pipeline for a while before they get released. So just because we got 17.5 last week, doesn't mean they only started on the next update after that time. They probably rolled some other fixes that were slated for a possible 17.6 release into this point release as well.

 

[tosbsas]

My CarPlay seems to be faster and more stable

 

[nortonandreev]

I guess it was a rushed release - my iPhone 15PM just crashed and rebooted itself.

 

[GoldenChild]

My CarPlay seems to be faster and more stable

Same here

 

[Ledsteplin]

The photos that reappeared came from the Files App. When deleted from the camera roll, they were not deleted in the Files App. And that caused them to reappear in the camera roll. It was all on your device. There was no security issue or anything like that.

But for people who thought they deleted some, er, naughty pictures only to have them magically reappear, this could be very inconvenient, to say the least.

Gotta luv those incognito fixes!

Nice but … this doesn’t explain how they came across devices that went through a new build.
*** scratches head ***

It’s a strange phenomena, not gonna lie. And I’m tempted to install, via IPSW, the 17.5 build just to see what happens.

They did fix it, afaik. All this tech stuff is not perfect. There will always be glitches.
