When exactly did 4S get out of jailbreak?

Don't worry, there is a lock, no lock: because China does not issue iPhones, our mobile phones are basically smuggled from abroad, and most countries' mobile phones are contracted machines in their own countries or in a fixed area, and they cannot be used after getting them in China. The locked version is a machine with an operator lock, which cannot be used directly when it is taken to Da*lu, and must go through xx (soft or hard decombining) of the machine.

For example, the American version, most of the European version, etc. The unlocked version is relative to the locked version, such as the Hong Kong version, the New Zealand version, the Italian version, etc. Because the unlocked version can be upgraded at will and does not have to consider the signal xx problem, the unlocked version is a little more expensive than the locked version.

xx: xx is also aimed at the locked version, that is, the problem that the locked version of the mobile phone cannot be played in China, xx is to use software to modify the official system to a certain extent, so that the locked function can play in the country. xx includes two ways: soft and hard solution:

The software solution has no damage to the machine hardware, and the software solution software required for the generation is yellowsn0w (the number 0 is in the middle of the sn w) by modifying the machine software system to achieve the xx mode of the xx mobile phone.

Hard decoding is a xx method that uses a card or disassembles the machine to modify the internal hardware of the machine to achieve the purpose of xx, which has a certain amount of damage to the machine.

Jailbreaking: Many crazy friends confuse xx with jailbreaking, in fact, it's not right, you know that Apple's online store App Store has a large number of software for ** (of course, there are also free), many** are very expensive, jailbreak is to allow players to xx these software, let our little i play software for free An operation process. The software required is Quick PWN (The Legendary Big Pineapple.

See if there is a way to jailbreak 4s:

1.If there is a Cydia icon in the iPhone app, it means that it has been jailbroken.

It is a tool that can install third-party software after jailbreaking, which is equivalent to a mobile phone assistant.

3.It is also convenient to make various patches to fix some problems in use.

4.If you don't have the Cydia app icon, it proves that your phone hasn't been jailbroken.

Jailbreak must have a software called cydia, you look at this, or install a Kingsoft battery, just look at the mobile phone information.

After the Apple 4s jailbreak, you can't directly restore the factory settings in the phone, otherwise it will become a white apple. That is, it has been parked in the boot state after shutting down and when it is turned on, the screen has a small Apple logo, and it can't enter the system, you need to restore the phone to the previous state of not jailbreaking, in order to restore the factory settings, you can use iTunes to restore, but it will not have the jailbreak function after recovery, the method is as follows:

3.You will then be prompted that if you continue to restore the iOS firmware, all data from the current device will be erased. Click "Recover" to proceed as below screenshot shown.

4.Then, the system extracts the firmware you just selected, verifies it, and prepares it for recovery as shown in the image below.

5.The next thing is to wait for iTunes to restore the new firmware to your iPhone and verify the recovery, as shown in the figure below.

6.When iTunes completes the firmware restoration, the device will automatically restart. Then set it up step by step according to the system prompts.

Of course, you can do a factory reset, but you need to jailbreak it again!

OK. Factory settings can be restored at any time, regardless of whether you are jailbroken or not.

But if you are firmware upgraded, the firmware cannot be restored.

Have a nice day!
