Then, click on the "Recover" button in the iTunes software with your mouse, the software will pop up a selection dialog box, and then we click on the next step.

Next, we will be prompted that if we continue to restore the iOS firmware, all data on the current device will be erased. Click "Restore" to continue, then, the system extracts our firmware, verifies and prepares for recovery, the next thing is to wait for iTunes to restore the new firmware to your iPhone, and verify the recovery.

Note: Before restoring your phone, you must remember to back up your data, such as your phone's contacts. Otherwise, all data will be lost once recovered.

Reason: Phone4S cannot be turned on, which is generally divided into two situations: software and hardware, of which the software factors cause the inability to boot, and account for the majority.

Solution: 1. Among the software factors, the most common situation is that the computer cannot be booted due to factors such as upgrading, installing and deleting applications, synchronization errors, and unofficial clients. The most common is that after pressing the power button, the iPhone4S displays the Apple metal logo for a long time, and cannot start normally, this fault is commonly known as "white apple".

2. In this case, we just need to connect the iPhone4s to the computer and open the iTunes client software on the computer. While holding down the Home button at the bottom of the screen (the only button on the front), press and hold the Power on lock button at the top of the screen, while keeping both keys behind the black screen of the iPhone4S screen, release the Power on lock button until the computer displays that new hardware is detected, then release the Home button. At this time, the computer's iTunes will automatically detect the iPhone4S device in recovery mode, and you only need to click Restore to restore the iPhone4S system to factory state.

Software glitches are resolved.

3. If the recovery system is interrupted unexpectedly, or an error is prompted in the recovery system and the computer cannot be turned on, this situation is generally caused by the system version not matching or the iTunes version used on the computer is too low. All you need to do is change your computer or use the latest version of the iTunes client and restore it.

4. In hardware failures, due to not using the iphone4s for a long time, the battery power is too consumed and the device cannot be turned on the most. In fact, in this case, there is no need to go to the repair station at all, generally only need to connect the iphone4s, connect to the charger (it is best to use the original charger or ipad charger), and patiently charge the battery overnight or longer, and the iphone4s will come back to life.

5. In rare cases, users will also encounter the situation that the system is locked. Appears to be unresponsive or slow to respond to key presses. This situation is relatively rare, generally only need to press the boot lock screen button and home button at the same time for about five seconds, forcibly shut down, and perform a hard start of the system to solve the problem.
