An iOS ipsw (offline installer) may come helpful when the OTA-based software update fails on an iPhone. It often happens when there are storage, billing, or network connectivity issue with the iOS devices. In iPhone, you will get errors like “unable to check/verify update.” in such scenarios. Thankfully, it is possible to download iOS 14, iOS 15, and older versions like iOS 12 directly from Apple as an IPSW file. One can use the downloaded file (full iOS installer) to update multiple iPhones offline and fix all issues with installation.
Download iOS 14.7.1 &12.5.4 ipsw (firmware) for iPhone
Recently I had to download iOS 14 IPSW for resetting my iPhone and test an issue with my contact photos. Of course, you can do it from the iPhone’s settings, but “factory reset” is a safer option when you want to sell your device. Also, an offline software update is the best way to recover an iPhone if it’s bootloader is corrupt, the screen is stuck, or it is not getting detected on a desktop system.
Downloading iOS offline installer helps you fix the software update issues like,
- Unable to verify update- iOS 14.7.1/12.5.4 failed verification because you are no longer connected to the internet.
- Unable to check for update- an error occurred while checking for a software update.
Some of the jailbreaking tools for the iPhone also needs iOS IPSW for offline update requiring through a desktop computer.
Apple does not provide a direct link for the iOS installer on their website or other public platforms. So one has to search the internet to find the iOS IPSW links every time if he wishes to do an offline restore. The disadvantage here is the size of the iOS offline installer, which is about 5-6 GB when you download the full file.
Direct link for downloading iOS 14/12 IPSW (iPhone software)
Sometimes an older iPhone may not get a direct update to the latest version of iOS, 14.7.1 released on July 26th, 2021. You may need to download a release compatible with your current settings and then update it to iOS 14.7. But if your device supports, it is always good to download the iOS 14.7 directly and update it in the offline mode. After this, you can opt for future updates through the iPhone’s built-in OTA system.
What you see above is iOS 14.7.1 changelog. Now if you want to know about other iOS 14 releases or iOS 12.5, please visit the Apple webpage for iOS 14 and iOS 12. Select a version number to read all about old and new updates.

As of 2021, iOS 14 is not compatible with iPhone 6, 6 Plus, and iPhone 5S, which many people are still using. Those who own these old devices may get iOS 12.5 offline installer from the link given below.
Prefer downloading the iOS ipsw installers using the web browser if you have a stable internet connection. Using third-party software like IDM may speed up the download, but it might save the downloaded iOS ipsw as a ZIP file. However, it is easy to convert back; change the extension of the file to .IPSW before restoring it through iTunes.
How to install iOS 15 beta with IPSW file.
Beta testing for the upcoming iOS 15 is still going on, and the fourth iteration got released yesterday on 28-07-2021. It may take a couple of weeks for Apple to push the final build of iOS 15 to eligible devices. However, if you sign-up for the iOS 15 Beta program and install the Beta profile on your iPhone, you could try and experience the new OS right now.
After installing the Beta profile, you can download iOS 15 ipsw and restore it to your iPhone offline, as explained below. You could also check for the software update manually on your iPhone’s Settings and upgrade the device to iOS 15 beta.
Steps to update iPhone software offline with iOS 14.7.1/iOS 15 Beta ipsw
Remember to take a local backup of your iPhone before proceeding with the iOS 14.7 or iOS 12.5.4 offline update. It helps you quickly setup your new iPhone or re-install the data on the same device after a factory reset. We use iTunes for offline installation of iOS on iPhone in Windows and macOS versions up-to Mojave. Those who are upgraded to macOS Catalina may just use the Finder to complete the update process.
- Connect the iPhone to a Mac or PC.
- Using an old version of macOS, or Windows? Download and install the latest version of iTunes for Mac, or Windows 32-bit or 64-bit.
- Now open iTunes or a new Finder window and wait for the system to detect your iPhone.
- Once the iPhone shows up, take a local backup if your device is in working condition.
- When you are ready, click on the “Restore iPhone” button, and at the same time, press the Option/Alt key (Mac) or Shift key (Windows).
- Then select the downloaded iOS 14/15 IPSW files, and wait for the system to complete the offline software update.
You might need to put your iPhone in DFU mode if it is not appearing on Finder or the iTunes app for some reason. Have a look at this guide on Apple.com for more details on this process.
Location of iOS offline installer (ipsw) saved on a Mac or Windows PC
If you update iPhone software directly on iTunes, the app saves a copy of the IPSW file on one of the system folders. It is the same offline installer we get through the direct links on this page. Now if you want, you can copy and save this full iOS installer from the directory shown in the screenshot.
I’m able to find iOS 14 firmware from the above location in macOS High Sierra, but I couldn’t confirm the same for Big Sur.
