iPhone jailbreak process
Requirements: A jailbroken phone;
Device: iPhone5, iOS9.2.1;
Question: How to jailbreak?
I will record my jailbreak process below for future study.
1. Jailbreak tools
There are many jailbreak tools on Baidu Yisou, and the most commonly used ones are "Aisi Assistant" && "PP Assistant".
Jailbreak has certain requirements for mobile phones and systems.
Device: iPhone 5, iOS 9.2.1 system.
After searching a lot of information, they all said that jailbreak is not possible.
Finally, I tried to upgrade the system to 10.3.3, and then used "Aisi Assistant" h3lix to jailbreak successfully.
The tool page is basically as follows, just follow the prompts.
Possible problems:
1. 
At this time, you can try to disconnect from the network and try again.
The successful installation of h3lix is as follows, just follow the prompts.
2. After jailbreak
1. Cydia cannot connect to the network
to solve:
Open Cydia -----> Enter the installed list
-------> Click Cydia Installer to uninstall,
-------> Then you will see that there is no Cydia on the desktop. icon,
------->Then restart the phone, open h3lix 重新越狱, Cydia will be automatically reinstalled,
------->Open Cydia and you can access the Internet. However, this method can only be applied to h3lix.
------->Cydia download ConditionWi-Fi, and then turn on Cydia's networking in the settings. At this point, Cydia can be permanently connected to the Internet. (Without modification, it is impossible that Cydia will reappear the problem of being unable to connect to the Internet at some point.)

Attachment: Many recommended it when searching for information 下载『乐网』来解决
, but I couldn't download and install "Lewang", so I finally solved it with method 1.
2. Download the software
1. Connect the computer to the mobile phone, open the "AISI Assistant" client to download and install;
2. Download and install the "AISI Assistant" app on the mobile phone.
PS: This jailbreak seems to be a non-perfect jailbreak. There may be some problems in the later stage. We will solve them when we encounter them. To be continued. . . .
