Free Up iPhone Storage Space<\/h2>\n\n\n\n<p>If your iPhone is running low on storage, it might not have enough space to complete the update process. iOS updates can require several gigabytes of free storage to download and install. Apple recommends having at least 1-2 GB of free space for a smooth iPhone update.<\/p>\n\n\n\n<ol start=\"1\">\n<li>Go to <strong>Settings &gt; General &gt; iPhone Storage<\/strong>.<\/li>\n\n\n\n<li>Review which apps or <a href=\"https:\/\/lightningxvpn.com\/blog\/en\/files-on-iphone\/\" target=\"_blank\" rel=\"noopener\" title=\"\">files on your iPhone<\/a> are taking up space.<\/li>\n\n\n\n<li>Delete unnecessary apps or offload videos, photos, and documents.<\/li>\n\n\n\n<li>Try updating your iPhone again after freeing up storage.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">4.

Remove the Update and Download Again<\/h2>\n\n\n\n<p>If you can\u2019t install the latest version of iOS on your iPhone, try removing the update and downloading it again.<\/p>\n\n\n\n<ol start=\"1\">\n<li>Go to <strong>Settings &gt; General &gt; Storage<\/strong>.<\/li>\n\n\n\n<li>Find the iPhone update in the list of apps.<\/li>\n\n\n\n<li>Tap the iPhone update, then tap <strong>Delete Update<\/strong>.<\/li>\n\n\n\n<li>Go to <strong>Settings &gt; General &gt; Software Update<\/strong> and download the latest update.<\/li>\n<\/ol>\n\n\n\n<figure class=\"wp-block-image aligncenter size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"305\" height=\"457\" src=\"https:\/\/lightningxvpn.com\/blog\/wp-content\/uploads\/2025\/09\/fix-cant-update-iphone-1.png\" alt=\"download the latest iOS update\" class=\"wp-image-71671\" srcset=\"https:\/\/lightningxvpn.com\/blog\/wp-content\/uploads\/2025\/09\/fix-cant-update-iphone-1.png 305w, https:\/\/lightningxvpn.com\/blog\/wp-content\/uploads\/2025\/09\/fix-cant-update-iphone-1-200x300.png 200w\" sizes=\"(max-width: 305px) 100vw, 305px\" \/><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">7. Use iTunes to Update iPhone<\/h2>\n\n\n\n<p>If you can\u2019t update iPhone through the over-the-air (OTA) update, you can use iTunes to manually update your iPhone.

Use Mac Finder to Update iPhone<\/h2>\n\n\n\n<p>If you have a Mac running macOS Catalina or later, you can use Finder to update your iPhone.

Fix Software Glitches Using DFU Mode<\/h2>\n\n\n\n<p>If your iPhone update is still stuck, entering DFU (Device Firmware Update) Mode can help you restore your device. This method is particularly useful if there&#8217;s a deeper software issue. Be sure to back up your data before proceeding.<\/p>\n\n\n\n<ol start=\"1\">\n<li>Connect your iPhone to a computer.<\/li>\n\n\n\n<li>Open iTunes or Finder and ensure it&#8217;s ready for device recognition.<\/li>\n\n\n\n<li>Press and release the <strong>Volume Up button<\/strong>, followed by the <strong>Volume Down button<\/strong>.<\/li>\n\n\n\n<li>Press and hold the <strong>Side button<\/strong> until the screen goes black, then press and hold both the <strong>Side button<\/strong> and <strong>Volume Down button<\/strong> for 5 seconds.<\/li>\n\n\n\n<li>Release the Side button while continuing to hold the Volume Down button for an additional 10 seconds.<\/li>\n\n\n\n<li>If done correctly, the screen will stay black, and your iPhone will be in DFU mode.<\/li>\n\n\n\n<li><strong>iTunes\/Finder<\/strong> should detect the device in recovery mode and prompt you to restore or update the device.<\/li>\n<\/ol>\n\n\n\n<h2 class=\"wp-block-heading\">10.
