IPSW-250x250.png
Following the release of iOS 12.4 on July 22, Apple has stopped signing iOS 12.3.1 and iOS 12.3 the previous versions of iOS that were available to consumers. Apple is also no longer signing iOS 12.3.2, an update exclusive to the iPhone 8 Plus.

iPhone, iPad, and iPod touch owners who have upgraded to iOS 12.4 will no longer be able to downgrade to iOS 12.3, 12.3.1, or 12.3.2.

iOS 12.4, available on all devices able to run iOS 12, was a major update with Apple News+ improvements and a new device-to-device data migration option when setting up a new iPhone.

Apple routinely stops signing older versions of software updates after new releases come out in order to encourage customers to keep their operating systems up to date.

iOS 12.4 is now the only version of iOS that can be installed on iPhones and iPads, but developers and public beta testers can download iOS 13, an upcoming update that's currently being beta tested.

Sure wish I could install 12.4. iPhone XR stuck at "Update Requested...". I could upgrade using iTunes, but my MacBook Air is lacking enough space. Resetting phone is not an option.
 
This is good for the security of all iOS users.

It does force users into later, more secure version of the OS. This is one of the often un noticed advantages iOS has in the mobile marketplace. Control over the OS and the hardware is still an advantage. Most Android users are on an old, outdated OS version that they simply can’t update due to constraints placed on them by their device manufacturer.

A lot of people crow about how much more versatile Android is because it’s “open” but most of them never delve into that versatility, or when they do are bit in the but by side loaded applications. All they’re left with is an eventually orphaned device.

For most people, this versatility is not an advantage...
 
Well I finally bit the bullet and went from iOS 10 to iOS 12 on my iPhone 7+
I’ve been kicking the tires with with iOS 12 on my 6 and mostly good experience so it was time.
I’ve found enough apps to bypass my 32 bit apps that are my daily drivers. Alas loosing some games and utilities.
Now I can stay on an iOS that’s still compatible with older iOS devices like my 6 and my friend’s 5S so we don’t get those squares when we iMessage.
As soon as iOS 13 is dropped by Apple they’ll stop signing 12 and I’ll miss the window.
There must be huge indexes because it went from 44GB free last night to 17GB free. Also there was some photo memory alert. Maybe that’s eating up space. Made sure photos saved in JPEG.
 
After updating from iOS 10 to 12 I’m having trouble maintaining cell signal. I keep getting no service. Reset several times but this morning it didn’t have a signal and my 86 yr old mom couldn’t reach me at 6am!
I’m hoping with the sprint T-Mobile merger that we’ll soon have more towers to connect.
 
12.4 is a stellar release, IMO, on my max and xr. Works great on my 5s also.
Shame it didn't fix all six Zero days with iMessage I belive. it had six fixes but one CVE is still listed as vulnerable by Project Zero who are not releasing the information at this time, as it takes no intraction from the user which is scary, so I imagine we will see a 12.4.1 or whatever its called to patch the last vulnerability quite quickly.

"Details about one of the "interactionless" vulnerabilities have been kept private because Apple's iOS 12.4 patch did not completely resolve the bug, according to Natalie Silvanovich, one of the two Google Project Zero researchers who found and reported the bugs."

Been living with windows zero day vulnerabilities for 10+ years and I consider the surface area of attacks for windows far greater than iOS. Apple will release 12.4.1 that will resolve the last issue.

Its the lack of user interaction thats more concerning again with these CVE's, more of these bugs seem to be occurring, but as iOS gets more complicated its bound to happen. Windows is actually pretty tight these days, it has its Zero days but its not the monster it was, I could go back to windows (privacy issues with 10 not withstanding) now if I didn't have my iMac.
 
My Home app is hosed after updating to 12.4. It’s stuck on the WSOD (White Screen of Death) displaying “Loading Accessories and Scenes. I’ve been working with an Apple Support representative, who in turn, escalated my case to engineering. I’m on Day 3 with Apple and this issue. Supposed to get another call today and see if engineering has found the problem.

That’s the point these zero days sound scarier than they are because their success also depends on the ease of infection and whether physical access is needed. But still would like to erase this one from the books.
 
My big risk I took yesterday going from iOS 10 to iOS 12 on my iPhone 7 Plus was the software bug that fails the microphone requiring a $300 repair.
Fortunately all went well for me. Can’t be said for others.

What’s interesting is android users are often price conscious—yet they do not realize their phone will last years less than an iPhone.
 
I am not at all pleased with this. I foolishly updated my iPhone 6S from iOS 11 to 12.3.1 without checking to see if there was a jailbreak available. I have Automatic Updates turned off, and have been waiting for a 12.3.1 jailbreak. The other night, I left my phone alone for a few minutes, and it updated itself to 12.4. This is infuriating! I downloaded the 12.3.1 .ipsw as fast as I could and tried to downgrade it to no avail. Apple stopped signing it immediately after forcing the update.

My jailbroken iPhone 4 running iOS 6 (I wish it was 5) is more functional than my phone running iOS 12. I can do all the tasks I regularly do with a swipe, tap, or double tap on a certain area. I was absolutely dumbfounded at how little progress Apple has made as far as usability is concerned and every update just gets uglier and uglier. I'm not a fan of the flat, cheap knock-off of iOS look that has plagued us since iOS 6 and Yosemite. It looks like it was designed by color blind kids working in a Korean slave labor camp drawing icons with out-of-the-tube colors and their hands behind their backs. At least with my jailbroken iOS 6 phone, I can restore the professionally designed icons and dock.

I was waiting patiently so I could make my iPhone usable, but they literally forced this update without permission. Jailbreaking aside, I don't like to update ANYTHING until I know it doesn't break anything important. Is there any way to force a restore to the older iOS after Apple has stopped signing it? This is just dirty pool. When I buy a device and tell it not to update, I expect that choice to be respected. I was the biggest proponent of Apple since the release of OS X Public Beta in September of 2001 and sold millions of dollars worth of stock and hardware for them up until they fired Scott Forstall and put that insane minimalist Jonny Ives in charge of OS development. The man has no clue. There are so many things that STILL don't work after all the years he's been in charge of destroying Apple software. For instance, you still can't adjust the speed that media scrubs by pulling down from the scrub bar like in iOS 5 and before. And when selecting text, it doesn't scroll down past what's on the screen when you reach the end of what's displayed. Why in the world would they break these things that made the user experience so simple and elegant?

You used to be able to give an iPhone to anyone and they could use it easily. Now, there is a manual that is 3000+ pages in Books because the interface is so unintuitive. It's minimalism to the point of insanity. Not only that, the quality of the apps has declined remarkably. People who have been getting slowly boiled like frogs probably don't notice it, but when you suddenly go from a highly functional piece of art to a dumbed down, eyesore imitation of what was once great, the shock is palpable. I have tried dozens of apps to manage my prescription medications, and none of them come close to the features of the app I used in iOS 4–6. Same with apps for lists, date calculators, and many more. I have to carry around 2 phones because there are simply no replacements for things that are vital to my day-to-day use. I used to be accused of being a fanboy, but I was just enthusiastic about the genius and quality standards that Steve Jobs and Scott Forstall were injecting into the products. Then, not long after Jobs died, they pushed Forstall out because he refused to release crap or compromise quality—just like Steve. Since he's been gone, it's a been a downhill slide and I can't believe so few people notice it. They have truly drunk the Kool-Ade and are like lemmings. They will gladly swallow whatever crap Apple puts out and think it's great without noticing the decline.

With their aggressive release schedule, they barely get an OS working before they release a new one. The least they could do is allow users to opt out of forced updates! The really ironic thing is that they used the Maps app in iOS 6 as the excuse to fire Forstall, and it's not any better than it was! I am on a very tight budget due to a disability, and I spent what is a lot of money for me to buy an unlocked iPhone so I could go Google-free, but the keyboard in iOS is still an absurdly dysfunctional relic that hasn't improved, and the Maps app is just as bad as it was in iOS 6, so I'm having to use Gboard and Google Maps. At least the Gboard is somewhat sandboxed in iOS so every word I type doesn't go into Google's profile of my private life, but come on, Apple! They've gone from being the trend setter to a sad imitation as far as appearance and functionality are concerned, and this is as sad as it is aggravating!

Sounds like when it comes to jailbreaking iOS 12.4 is the version to be on.

iOS 12.4 actually reintroduces bugs that allow for privilege-escalation that were patched in 12.3 - you can see this in the jailbreak scene, tools that worked on 12.2 were never updated for 12.3, but were almost immediately available on 12.4.

I think this is the first time Apple has stopped signing firmware that can't be jailbroken in favor of firmware that can.

I’m thinking Apple was patching another vulnerability that regressed something else and Apple didn’t catch it, or they did and let it go anyway.
 
I have 12.4 on my iPad Mini 3. I think this is the last OS that I will be able to use on this machine. If so, will it still be available to me if I have to wipe and restore my iPad in the future?
 
iOS 12.4.1 is out now.

Whatever the latest/last update that is available to the device will basically always be available for it.
