Android Core Research & Development Team (ACRDT)
Proudly Presents You The
Droid Dual Boot Tool


Introduction

We from the Android Core Research & Development Team (ACRDT) are glad to present you this “Droid Dual Boot Tool”, which does all the necessary steps to make your device dual boot. All you have to do is flash the zips as mentioned below. The main focus of this tool to help all Android Users to understand and have dual boot OS in their smartphone in a user friendly manner. This tool takes all the coding, so with a single click of mouse you can have dual boot. Awesome Right!! Keep Reading...
This Whole Concept was a Big Gigantic Hack by ACRD Team.
**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..

    It´s the same error like everytime you make a backup with lockscreenprotection and restore it...
    There´s an easy solution:
    Just go to twrp -> filemanager and delete the following files in user/system:
    gatekeeper.password.key
    gakekeeper.pattern.key
    locksettings.db
    locksettings.db-shm
    locksettings.db-wal
    That´s it!
