You need to manually put the iPhone in recovery mode, which allows you to erase the iPhone so that you can reset it. After erasing the iPhone, you can set it as a new device, and then download any data you have stored in iCloud.

Press and hold the correct button corresponding to the iPhone model, and immediately connect the iPhone to the computer through the data cable. Don't release the button. Continue to press and hold the button until you see the recovery mode screen on the iPhone, and then release the button. After successfully connecting with AISI Assistant, the software will also prompt "recovery mode".

On the iPhone, the most direct way through the screen will also be shown to you. In short, at the bottom of the screen, your device will display the "Erase iPhone" option.

Not all versions of iOS will display this option, and older versions do not provide this option. In this case, you must directly use 4uKey to get the entry.

You also need to prepare the details of the AppleID so that the erasing operation can be completed locally. With the widespread use of password managers, this situation is not uncommon.

Why does iPhone display "iPhone unavailable"?

When you wake up the iPhone, you usually use face ID or touch ID to unlock it, or use a password if these passwords fail. However, in some cases, such as after reset, you need to enter a password.

Password entry is always available, but this may be a problem. For example, accidentally waking up the iPhone and repeatedly typing the wrong number may be considered as a password input failure.

It is also possible that someone tries to guess the password of the device to gain access. Some may try too many times, causing the iPhone to lock.

If the password is not entered correctly after five attempts, the iPhone will not appear on the screen. After five failures, users will be told to wait and try again, and after ten attempts, iPhone will stop accepting any further attempts.
