Jailbreak refers to bypassing Apple's many restrictions on the operating system on its device, so that it can "Root access" the basic operating system. Simply put, "jailbreak" allows iPhone users to download other unofficial applications from outside the Apple App Store or customize the user interface. Literally, it's like a prisoner who escaped from a deep prison and gained his freedom; And there are no constraints.
brief introduction
The so-called jailbreak refers to opening the user's operation authority, so that the user can erase the running state of any area at will, that is, using jailbreak software to remove the restrictions of the original firmware of the mobile phone system, so that the user can customize the installation of unofficial or third-party applications.

Advantages and disadvantages of jailbreaking or not
First, don't escape from prison
Advantages:
1. Save electricity.
2. The system is relatively stable.
3.3. The software downloaded and installed by Apple Store has strong compatibility.
4. The software downloaded and installed by Apple Store (ipa format) will not leave redundant system junk files after being deleted.
Disadvantages:
1. System-level software, such as incoming call, SMS display of attribution, SMS receipt, flash, can never be realized without jailbreaking on iphone.
2. The system authority is very low. For example, we can't delete system programs, modify system files and settings, encrypt a program, send files with Bluetooth, use third-party input methods, etc ... and third-party software can't be realized. Why? Application developers want to put on the APP Store, and their works must also be approved by the Apple App Store.
3. Only free programs or software downloaded from the App Store can be installed (China usually buys gift cards or black cards and redemption codes from Taobao). Unable to install the cracking program (software without account certificate, such as cracking. ipa，pxl，deb)。
4. Personalized programs such as themes, icons and short messages cannot be changed.
5. You can't use your mobile phone to download files directly in the browser and manage files on your mobile phone.
Second, after the prison break
Advantages:
1. On the basis of the original background running function when iOS4.x was not jailbroken, some programs that do not support background running can support background running.
2. The system has high authority and can optimize the system and modify the system files by itself. You can install more software with high system authority and realize more advanced functions! For example: sending files with other devices via Bluetooth, SMS receipt, call attribution, call answering vibration, file management, browser downloading plug-ins, flash plug-ins, content management, etc.
3. You can install both free programs and cracking and charging programs.
4. You can change the theme, icon, SMS and so on to create a personalized mobile phone.
5. You can flexibly manage the system or other files with the help of third-party file management software. Think of the iphone as a removable hard disk (USB flash drive).
Disadvantages:
1. It needs electricity. After jailbreaking, the system will always keep some processes in jailbreaking state. Depending on the number of installed system-level software (deb format), in some cases, the power consumption speed will increase by about 10% ~20% after jailbreaking. Note: Never install software in pxl format (for example, most of 9 1 mobile assistants are software in pxl format).
2. It may cause system instability. While we have high system authority, we are also in danger of system collapse. Can you understand this truth? It can be revised, but it cannot be guaranteed to be corrected forever. Therefore, it is better to have system-level software than to abuse it. If you don't understand the purpose, don't install it indiscriminately.
3. When the new mobile phone firmware version comes out, don't update it in time unless you back up SHSH with a mini umbrella. Because every new version of firmware will fix the jailbreak vulnerability of the previous version, jailbreak will be invalid. And Apple's iOS firmware can only be upgraded, not downgraded. Therefore, if you still need to maintain the function after jailbreaking, it is best to wait until the new jailbreaking program is released, and then formally upgrade the corresponding mobile phone firmware version.
4. There is a small bug in the process of jailbreak, but it has no effect on normal use.
Third, * * * similarities.
Free or paid software downloaded from 1 The apple store can be installed without being affected.
2. It will not damage the hardware, and jailbreaking will not change the hardware on any mobile phone.
Excuse me, what does Apple's jailbreak mean?
Lock or unlock: Because the iphone is not distributed in China, our mobile phones are basically smuggled from abroad, and most mobile phones are contracted in their own countries or fixed areas, so they cannot be used after being obtained in China. A locked version is a machine that is locked by an operator. You can't use it directly when you get it. It must go through XX (soft decoding or hardware decoding) machines. For example, the American version, most European versions and so on. The unlocked version is relative to the locked version, such as Hong Kong version, New Zealand version, Italy version and so on. Because the unlocked version can be upgraded at will, regardless of the signal XX, the unlocked version is more expensive than the locked version.
XX:XX is also aimed at the locked version, that is, a mobile phone with a locked version of XX cannot make calls in China. XX uses software to modify the official system, so that the locked version can make phone calls in China. XX includes soft solution and hardware decoding:
The soft solution has no harm to the hardware of the machine. By modifying the machine software system, the XX mode of XX mobile phone can be realized. 1 and the soft solution software needed by the second generation is Huang Xue Yellow0W (the number 0 in the middle of SNW).
Hardware decoding is a way for XX to do some damage to the machine in order to modify the internal hardware of the machine by using card pasting or disassembling.
Prison Break: Many crazy friends confuse XX with prison break, which is actually wrong. As we all know, Apple's online store app store has a lot of software for sale (and of course it is free), and many of them are expensive. Jailbreak is an operation process that allows players to play these softwares for free.
I hope I can help you. As for how to escape from prison, the suggestion is that you go to the mobile phone shop. Your own words are more troublesome.
Apple 6 mobile phone jailbreak is
Apple 6 mobile phone jailbreak is to crack the operating authority of open users, so that users can modify all areas at will.
However, due to excessive openness, the security of the system has also decreased. There are advantages and disadvantages after jailbreaking, and you need to decide whether to jailbreak according to your own needs.
Advantages after prison break: 1. Based on the background running function of the original system without jailbreaking, some programs that do not support background running can support background running. 2. The system has high authority and can optimize the system and modify the system files by itself.
More software with high system authority can be installed to achieve more advanced functions. For example: sending files with other devices via Bluetooth, SMS receipt, call attribution, call answering vibration, file management, browser downloading plug-ins, flash plug-ins, content management, etc.
3. You can install both free programs and cracking and charging programs. 4. You can change the theme, icon, SMS and so on to create a personalized mobile phone.
5. You can flexibly manage the system or other files with the help of third-party file management software. Think of the iphone as a removable hard disk (USB flash drive).
Disadvantages after prison break: 1. Power consumption. After jailbreaking, the system will always keep some processes in jailbreaking state. Depending on the number of installed system-level software (deb format), in some cases, the power consumption speed will increase by about 10% ~20% after jailbreaking.
2. This may lead to system instability. The high authority of the system is accompanied by the danger of system collapse, so the system-level software is in short supply, so don't install it indiscriminately if you don't know the purpose. 3. When the new mobile phone firmware version comes out, it can't be updated in time.
Because every new version of firmware will fix the jailbreak vulnerability of the previous version, jailbreak will be invalid. And Apple's iOS firmware can only be upgraded, not downgraded.
Therefore, if you still need to maintain the function after jailbreaking, it is best to wait until the new jailbreaking program is released, and then formally upgrade the corresponding mobile phone firmware version. The mobile phone is definitely not guaranteed, because it is not the original product of Apple, but a modified product, which is not covered by the warranty.
