iPhone – How to Install iOS via an IPSW File

Description: Want to manually restore your iPhone’s operating system using an IPSW file? This video shows you how to downgrade to a previous signed version or fix issues when standard updates fail. I’ll walk you through checking if a firmware is still signed on apple.sn.info and identifying whether your device is Global or Chinese by inspecting the SIM tray so you can download the correct file. You’ll learn to enter Recovery mode via the power and volume buttons, and I provide a timed guide for the more difficult DFU mode: hold the side button for eight seconds, then five seconds on volume down while holding Shift (Windows) or Option (Mac) to select your local IPSW. Be aware that this process erases all data and prevents restoring backups made on newer iOS versions, so you must manually copy important files beforehand; after restoration, you will need the credentials of the previously signed Apple account to bypass activation lock.
