Realize system downgrade with checkra1n

Reference: https://ioshacker.net/forum.php?mod=viewthread&tid=221&highlight=%E9%99%8D%E7%BA%A7

Scope of application

Model: iPhone 5s-iPhone X (so IPhone 5 should not be supported)

System: iOS 12.3 and above (so those ios10.xx, 11.xx may need to be upgraded)

 

Precautions

1. Based on checkra1n 0.9.2 version

     The green icon below is still in the testing stage, but it is said that you can jailbreak through the command line. The command is as follows:

./checkra1n.app/Contents/MacOS/checkra1n_gui -

The above is online, but the actual test found that the file could not be found. The following is my actual test success:

cd /Applications/checkra1n.app/Contents/MacOS/
./checkra1n_gui -

, The ones marked in red shouldn’t have to think about it

2. After restarting the phone, the jailbreak is invalid and needs to be jailbroken again

3. How to enter DFU mode, refer to: https://ioshacker.net/forum.php?mod=viewthread&tid=221&highlight=%E9%99%8D%E7%BA%A7
