How to update iOS 12 to iOS 13

To update to iOS 13, you will need to have an iPhone that is compatible with iOS 13. You can check if your iPhone is compatible by going to Settings > General > About and looking for the Model number.

Once you have confirmed that your iPhone is compatible, you can follow these steps to update to iOS 13:

1. Back up your iPhone: It's always a good idea to back up your data before installing a major software update. You can do this using iCloud or iTunes.
2. Connect to Wi-Fi: It is recommended to update your iPhone using a stable Wi-Fi connection.
3. Go to Settings > General > Software Update. Your iPhone will check for available updates.
4. If an update is available, tap on Download and Install. Follow the on-screen instructions to complete the update process.
5. Wait for the update to finish installing: The update process may take some time, so be patient and do not interrupt it.

Note: If you don't see the update, it may be because your device is not eligible for the update, or because the update is not yet available in your area. In this case, you will have to wait until the update becomes available or until your device becomes eligible for the update.

Here is the list of iPhones that are compatible with iOS 13:

• iPhone SE (2nd generation)
• iPhone 6s
• iPhone 6s Plus
• iPhone 7
• iPhone 7 Plus
• iPhone 8

To check which model of iPhone you have, go to Settings > General > About and look for the Model number.

Your unidentified iPhone model (for sure a 5s, 6 or 6Plus) cannot support iOS versions beyond 12.5.6, because of hardware (CPU/RAM) incompatibility, sorry.
