A situation where it is necessary to update the software iPhone 8, and the Wi-Fi network is unavailable or unstable, is a familiar problem for many users. Mobile data often has a data cap, and a standard over-the-air update may require a wireless connection to download large installation files.

Luckily, the company Apple provided alternative methods for installing the new version iOS, which don't rely on a wireless router. You can use a personal computer or laptop with synchronization software installed. This method is considered more reliable, as it minimizes the risk of system file corruption due to power surges or connection loss.
In this article we will discuss in detail how to update iPhone 8 Without Wi-Fi, using a wired connection. We'll look at using official utilities. iTunes And FinderWe'll discuss the nuances of using a mobile hotspot and answer frequently asked questions from smartphone owners who encounter this problem.

Try a different USB port, preferably located directly on the motherboard (at the back of the PC) rather than on the front of the case. 3. Test the cable on another device—it may be damaged internally, even if it's charging. 4. Restart your computer and phone. In rare cases, you may need to reinstall the Apple Mobile Device Support drivers through the Windows Control Panel.
Using a mobile hotspot (tethering)
If you don't have a computer at hand, but you have a stable mobile Internet connection with a large tariff package or unlimited, you can try updating iPhone 8 Using another device's tethering mode. Standard over-the-air updates are usually blocked if the phone is connected to a cellular network due to the risk of exceeding the data limit.
However, there is a workaround. You can share the internet from another smartphone (Android or iPhone) via Bluetooth or USB cable, connecting it to your iPhone 8In some versions of iOS, the system recognizes this connection as more stable and may allow the update to be downloaded, although this does not always work and depends on the firmware version.
A more reliable option within this method is to create a Wi-Fi hotspot on another device (for example, an Android smartphone with an unlimited data plan) and connect iPhone 8 to this network. To your phone, it will appear as a regular Wi-Fi network, and cellular data restrictions will not apply.

Solution and errors during update
During the update process without Wi-Fi, users often encounter various error codes. For example, the error 1015 or 4013 This often indicates a problem with the cable or USB port. In such cases, replacing the cable with a genuine one or using a different port usually solves the problem.
If the process freezes at the "5 minutes remaining" stage and doesn't move for an hour, this may indicate a lack of space on the device or a corrupted downloaded firmware file. In this case, you should not interrupt the process with the reset button, as this could lead to a reboot loop. It's best to wait for the connection to time out and try updating again.
Another common issue is the inability to activate a phone after an update if it's connected to an unstable network. In this case, you may need to reconnect to iTunes or Finder to complete activation. The app will prompt you to complete setup once it detects the device.
