There are many people who are new, they do not know how to unpack, edit, and repack the system image of Phoenix OS. But those who are old are familiar with the subject, so I will tell those who know about it, even if they do not read this post, this post is basically for those who are new.
My method applies to any Phoenix OS, be it the official version or the unofficial version is equally effective in both of these tricks. We need a tool to unpack and repack the system image of Phoenix OS. We get a variety of tools online to unpack and report, but there are some that are much better,  Phoenix OS toolbox,  APT toolbox.
Why did system images need to unpack and repack?
There are some users of Phoenix OS who often face different types of problems and to solve these problems we have to unpack the system image. After unpacking, we see the main files of the system. We change and edit these files and then repack. Basically, these are the reasons why we have to unpack and repack the system image of Phoenix OS.
Warning: Please everyone does the work at your own risk, if there is any problem while doing the work then we will not be responsible.
How to unpack and repack system image?
Follow all our instructions to unpack and repack the system image of Phoenix OS properly otherwise, you will not be able to complete the task properly.
Step 01- Download Phoenix OS Toolbox or APT Toolbox and extract to C:\ drive. This software will not work properly if you extract the file to another drive or place without extracting it to the C:\ drive.
Step 02- Copy the system.img of Phoenix OS and paste it into the “In” folder of Phoenix OS Toolbox or APT Toolbox.
Step 03- Run the “EXE” file from the Phoenix OS Toolbox or APT Toolbox. Now you will see an interface like the picture below, press “Enter” from the keyboard here.
Step 04- After pressing enter we get a new interface like the picture below. I will select option number “3” for system image unpack. To select, you have to press number “3” from the keyboard and press “Enter”.
Step 05- After the Enter press a new interface will appear, and here we have to wait for some time for the process to be completed. After the process is complete we will see a new interface like the picture below.
Step 06- Now go to the “unpack” folder and you will see the unpack files of the system image, from there you can edit or change any file you want.
Step 07- After editing and modifying the file, re-open the “EXE” file and select the number “4” option for repacking. To unpack, select the number “4” from the keyboard and press “Enter”.
Step 08- You will see an interface like the picture below, select option “3” from here, and repack. If you have used other unofficial versions, follow the developer’s instructions.
Step 09- After sometime later your working process is done, now check the “out” folder to see the system.img file.
The above shows the process of how to unpack and repack the system image using the Phoenix OS toolbox. You can unpack and repack the system image in the same way through APT toolbox if you want and by following the above methods you can unpack and repack the system image of any Android x86 operating system not only Phoenix OS if you want. In that case, there must be Lollipop, Marshmallow, and Nougat operating system, it will not support if you go to the top level.
