Modern mobile devices Apple requires regular operating system updates to ensure security and stability. Users often encounter situations where their home network is unavailable, the connection speed is slow, or the router is unstable. In such cases, the question arises whether it is possible to initiate the upgrade process using only mobile internet or a personal computer.
Luckily, Apple has provided several scenarios for such situations. Starting with certain versions iOS, it's now possible to download large data packages directly over a cellular network, if your data plan allows it. Furthermore, the classic method using a cable and a PC remains the most reliable option, regardless of the wireless signal strength in the room.
In this article, we'll take a detailed look at all available methods and assess their risks and benefits. You'll learn how to properly prepare iPhone to the procedure to avoid data loss or system freezes. It's important to understand the technical nuances of each method before taking action.
Updating over cellular on iOS 13 and later
Since version iOS 13Apple engineers have implemented a feature that allows you to bypass the Wi-Fi requirement. Now, if your device is connected to a 4G or 5G network and has sufficient battery power, the system will prompt you to download the update. However, this method has its drawbacks. restrictions, related to traffic volume.
The size of a new operating system distribution typically exceeds several gigabytes. Carriers may block such downloads or charge additional fees for exceeding the limit. Before starting the process, make sure your data plan allows for large data transfers without significant financial losses.
⚠️ Important: Make sure you have an unlimited plan or a large data plan left, otherwise you may be unpleasantly surprised by your phone bill.
Activating this feature doesn't require any complicated steps. Simply go to the settings menu and select the update section. If the system sees a new version available but doesn't offer a "Download" button, check your cellular data settings. Sometimes you may need to manually enable mobile network usage for system services.
It is worth noting that the download speed through mobile Internet The download time can vary significantly depending on tower load and your location. Unlike a stable home connection, interruptions are possible. If the signal is weak, the download can take hours or even be interrupted mid-stream, requiring a restart.
Using a computer with iTunes or Finder
The most stable and time-tested method is to use a personal computer. This method doesn't rely on the wireless connection speed of the phone itself, as data is transmitted via a cable. You'll need a computer with an operating system. Windows or macOS and an original Lightning or USB-C cable.
For Windows and older macOS users, you will need to install or update the program. iTunesOn new Mac computers with macOS Catalina and later, the built-in iTunes performs the role of iTunes. FinderThe computer must have access to the internet, but this can be any source: wired Ethernet, Wi-Fi, or even sharing from another phone.
- 📱 Connect your iPhone to your computer using a cable and wait for the device to be detected.
- 💻 Open iTunes or Finder and find your device's icon in the interface.
- 🔄 Click the "Update" button to begin downloading and installing the new software version.
- 🔒 Do not disconnect the cable until the process is complete and the phone reboots.
The main advantage of this method is the ability to restore the system if something goes wrong during the process. The computer takes control of the process, caches update files, and monitors data integrity. This reduces the risk of getting bricked due to an unstable connection.
☑️ Check before connecting to a PC
If you're using macOS, the process is extremely simplified. In the window Finder You'll see full device information. The system will automatically check for new software versions. If the computer doesn't detect the phone, try replacing the cable or switching the USB port, as physical connection issues often block data transfer.
Recovery mode and DFU
In cases where a standard update fails to launch or the device freezes, you can use recovery mode. This is a more in-depth method of interacting with operating system, which allows you to reinstall iOS from scratch or update it, bypassing the standard checks on the phone.
To enter this mode, you need to perform a certain sequence of button presses on the device body. On different models iPhone These combinations vary. For example, on models without a physical Home button, you need to quickly press and release the Volume Up button, then the Volume Down button, then hold down the Side button.
| iPhone model | Steps to enter recovery mode | On-screen indicator |
|---|---|---|
| iPhone 8, X, 11, 12, 13, 14, 15 | Volume up, Volume down, Press and hold Side | Cable and computer |
| iPhone 7 / 7 Plus | Press and hold the volume down button | Cable and computer |
| iPhone 6s and later | Press and hold the Home button | Cable and computer |
After the cable image appears on your phone's screen, a message will appear in iTunes or Finder on your computer indicating the device is in recovery mode. Here, you can select "Update," which will attempt to reinstall the software without losing user data. If this doesn't work, you'll need to use "Restore," which will completely clear the memory.
What is the difference between refresh and restore?
An update preserves your photos, contacts, and apps, simply replacing system files. A restore completely erases the device and installs a clean system, requiring a backup beforehand.
Using the mode DFU (Device Firmware Update) is a last resort. It allows you to reflash your device at the lowest level, bypassing the iOS bootloader. This is useful if the update is interrupted at a critical stage, but requires precision, as the phone's screen remains black in this mode.
Sharing the Internet from another device
If you don't have access to wired internet on your computer, but you have another smartphone with a good data plan, you can set up internet tethering. This method allows you to create a local Wi-Fi network that your iPhone to download updates.
Enable tethering on the donor device. This could be an Android smartphone or another iPhone. Make sure data is enabled and a hotspot is configured. When the phone being updated connects to this network, it will treat it as a regular Wi-Fi connection.
- 📶 Enable "Tethering" on your device with mobile internet.
- 🔗 Connect the iPhone that needs updating to the created Wi-Fi network.
- ⚙️ Go to update settings and run the check.
- 📉 Monitor the temperature of your devices, as ethernet distribution can cause your phone to get very hot.
It's important to keep in mind that tethering consumes significantly more power. The donor phone's battery can drain quickly, so it's recommended to keep it charged. Furthermore, data transfer speeds may be lower than with a direct connection due to the double signal conversion.
⚠️ Important: When using Internet sharing, make sure that the donor device does not go into sleep mode or turn off the access point automatically to save power.
This method is advantageous because it emulates standard update conditions. The system sees no difference between a home router and a transmitting phone. However, connection stability depends entirely on the quality of the cellular network signal received by the transmitting device.
Preparing your device and creating a backup
Before making any intervention in the operating system, it is critical to back up your data. Even the most reliable method can fail due to a memory glitch or a power surge. backup copy — this is the only insurance against the loss of photos, correspondence and contacts.
You can create a backup via iCloud if you have at least some network access, or locally on your computer. A local backup is more reliable and creates faster, especially if you have a lot of data. In iTunes or Finder, select "Back Up Now" before performing any software manipulations.
Also check the free space on your device. To install the new version iOS A significant amount of space is required. If memory is low, the system may refuse to install or may not function properly after the update. Remove unnecessary applications or large video files beforehand.
Don't forget to check your battery charge. Even if the process is powered by a power outlet or a cable, the initial setup requires power. It's recommended to have at least 50% charge before starting. If the battery is worn out, it's best to keep the phone connected to a power source throughout the entire process.
Common problems and solutions
During the update process, users often encounter errors that halt the process. Error codes like 4005, 9, or 3194 can be alarming, but they are often resolvable. Most often, the problem lies with the cable, USB port, or antivirus software on the computer.
If the update gets stuck at the "Estimating Time" or "Downloading" stage, try interrupting the process and starting over. Sometimes, simply restarting both devices—your phone and your computer—can help. It's also worth temporarily disabling your firewall or antivirus software, which could be blocking the connection to Apple's servers.
- 🔌 Replace the USB cable with an original or MFi certified one.
- 🖥️ Try a different USB port, preferably directly on the motherboard (at the back of the PC).
- 🛡️ Disable third-party antivirus software during download and installation.
- 📡 Make sure the date and time on your computer are set correctly.
If the error persists, Apple's servers may be overloaded. This often happens during the first few days of major updates. In this case, it's best to wait a few hours or a day until the load on the infrastructure subsides and try again.
In rare cases, you may need to manually download the firmware file (IPSW) from the official website. This file is then manually selected in iTunes/Finder while holding down the Option key (on Mac) or Shift key (on Windows). This avoids possible automatic download failures.
