**Neither Device Manufacturer’s nor Android . Let It Like this.**

How it works?

Normally when you boot your phone, the kernel (or boot.img) file loads all the files from all partitions like /system, /data, /cache, /firmware…etc. So to have Dual Boot you need to edit the boot.img of the CustomROM such that it loads all the files from the /system2, /data2

To Achieve that We Partition the Device using Parted Commands in Zips ..We Uses Intelligent OpenRecoveryScript Commands To Flash them Automatically..In a Order Wise..

In a Short way I'm Explaining How this Stuff works.. our current rom which was in /system /data .we back up that rom .Our Script flash this Boot-To-Secondary_BackUp_Rom.zip this contains a modified recovery.& boot when we restores the rom it'll sent to /system2 & /data2 . Now what happens is our current rom is moved to secondary partitions.. Now /system /data are empty right so we can install our custom roms there ..

Check Out this Video & Zips If you want to know about how our Intelligent code Executes..
