How to make custom VMOS ROM for VMOS Pro
You must know
the basics of the Android ROM structure, and also be able to manage the files,
like editing build.prop, init.rc, copying files from flashable zip manually,
etc. I will not explain in depth of it since there are plenty of infomation on
XDA forum. Don't worry, you don't need any coding knowledge.
Do not expect that you can make a ROM of other Android versions like
Android 11 than the VMOS provided, or use the ROM from other devices. You would
need a kernel source from VMOS, VM drivers sources, AOSP project sources to
build and so on and make changes to VMOS app to support it properly. It's a lot
harder than you think. If you need other Android version, consider sending a
feedback to VMOS team. Dumb questions like this are subject to be ignored
Special thanks to 4pda forum for more info
Getting started:
Get VMOS from here: VMOS Virtual Machine Operating System
- Double Your Android System
Where to get the original ROM?
You can just backup your installed ROM and you will have a backed up zip file
on /storage/emulated/0/vmospro/backup.
Your rom will be downloaded along the path /data/data/com.vmos.pro/rom/ No
extension, this is a .7z archive.
And meta information along the path /data/data/com.vmos.pro/rom/rom_info/
Without extension, this is json.
If you have root, you can get original ROM files from
/data/data/com.vmos.pro/rom, but the problem is the ROM is in .7z archive and
you need to rezip it as .zip file. It is not recommended way to do and you will
likely getting ROM installation error
Here's how:
On the main screen, click the small settings icon of your ROM and choose System
backup
Start the backup. Let it run in foreground
After it's done, click OK
You will see the backup on /storage/emulated/0/vmospro/backup
Even modify on phone straight forward, without PC
Enjoy modding!
Modifying ROM
Adding Google apps, root and Xposed
I have uploaded my files that you can use to add files in the ROM
Copying Google, Root and Xposed files to the ROM is pretty much straight
forward
Root:
Recommended to use my modded Root. The package name has been changed to
com.andnixshpmt1.superuser
In order to get root work, duplicate daemonsu to su and sx in
xbin folder. I already did that in my modded Root
Cleaning up the file system
√ - The folder can be deleted

oem √ - something related to OEM
sys √ - a folder for drivers but we don’t have them
system × - this is the system itself :D
storage × - the internal memory of Roma
sbin × - system binaries
root and proc √ - have nothing to do with root

Warning:
Before you are sharing your rom, make sure to delete data folder since it may
contain sensitive data. It is important you DO NOT store any sensitive data in
VMOS whatsoever. I'm not responsible if your data got stolen
Installing ROM:
To install your custom ROM, click on 3 dots and choose Import local ROM.
I'm not sure what's the difference between Rec the VM (Restore) and Import
local ROM. I think it's to fully preseve data
Choose a file
That's all
