Link: Iphone Firmware Flash Tool
If you want a raw iPhone firmware flash tool link to download the IPSW file directly (to flash later via iTunes’ Shift+Restore method), you need a trusted repository. Never download IPSW from random forums or torrents.
Here is a professional tip: download and store at least two versions of firmware for your iPhone model—the current signed version and the previous stable version. Apple stops signing older iOS versions within 1-2 weeks of a new release. If you have the IPSW file saved locally, you can downgrade or restore without an internet connection.
You cannot simply "download" the firmware from the iPhone settings. You must download the raw file from Apple's servers.
Where to get the links: The safest and most reliable source for direct download links is ipsw.me. iphone firmware flash tool link
