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 16 older versions like iOS 15 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.

Recently I had to download iOS 16 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.

iOS offline installer unable to check verify for update

Downloading iOS offline installer helps you fix the software update issues like,

  • Unable to verify update- iOS 16.6/15.7.8 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.

Sometimes iPhones may not get a quick update to the latest versions of iOS as soon as they are released. When you check the software updates, it says “update requested”, and the screen stays there so long for many users. If you are facing any update error issues and want to update your iPhone to the latest version immediately, download the iOS ipsw and do an offline restore.
