Introduction :
I'm proud to present you the first dual boot project for the Qualcomm-based Samsung Galaxy S3 Neo and Samsung Galaxy Grand 2 and Galaxy S5 mini ! This will allow any ROMs and as many as you want to be installed at the same time. It works by patching the secondary's ROM installation scripts and boot image to load the ROM files from an alternate location (/system/dual, /cache/dual, and /data/dual). Because of the way this is implemented, no changes to the primary ROM are necessary
About :
Hello guys, as some of you guys know and some of you dont I was working on dual boot and dual boot v1 beta, which was released in our great Telegram group, but not in XDA, because of some reasons and rude MAXSIMUS96 that doesn't have any respect to a great development. But anyway I dont care
Lets Start
Well here's v3 + dbtools removed
patched files are flashable with recovery now
added full s3 neo support :angel:
added full grand 2 support :angel:
added full s5 mini support :angel:
more
Now you can have unlimited ROMs!
Tested with 4 CMROMs + 2 stock ROMs
Here's the topic of the base tool used: Dual Boot Patcher
Here
Make sure you leave a like on the great post of base tool I used here
What is Dual Boot or Multiboot?
DualBooting or multi Booting means having 2 or more ROMs at same time on the phone and choose between what you want to boot on next reboot
Why i need this? Is it even useful???
Yes it is! You can fix offline charging on some ROMs like CM12.1, you can have stock battery life, motion beauty, CM12.1's and CM11's performence at the same time without flashing any of them. Just one click from changing to the ROM you like
Whoa that sounds awesomeeee! is it difficult to install??
In v1 yes, but now on v1.5 i added dbtools (DualBootTools) that make most of things automated and even easier for noobs
now v2 things got even easier full s3 neo support
Any ScreenShots !?
see post #3 attachments
I want to see how it is ! is it possible , any videos ?? !?
see post #3 post
First Things first ! Go and make Backup of your files
Requirements :
an S3 NEO
root access of course
busybox if you are on stock ROM
recovery (twrp 3.0.0 is the best)
brain (the most important)
time and being relaxed
downloaded files
installation tree:
download and preparing files
setting kernel
patching the ROM
flashing
switching ROM
updating ramdisk
extras...
done enjoying
Explaining the tools
First: dbtools (removed due v2)
DualBootPatcher:
the great app mentiond above that made dualbooting possible
installation :
Now we know all about the tools,so it's time to use our brain
Step 1
download and install DualbootPatcher app
if you are in motion rom do this
if you are on motion rom install Motion fix zip at downloads section . it will change device codename back to s3ve3g
Step 2
Open the app
Slide the menu and go to ROMs
It will request for root access
Allow the root access
and a message will ask about to set the kernel
Select "set now" and after it said kernel set now
Step 3
reboot your device
Now after device is turned on
Go to the app and navigate "Patch Zip File" from the menu
and tap that + button select zip of ROM you want to patch
A window will come up and if you see in "your device selected by default" you done everything right.
then:
If you are CMuser ( means you have a cm12.1 , cm11 or ... on your primary rom)
and want to install another cyanogeonmod rom (cm11 , cm12.1 ...)
Select the partition configuration as "Secondary"
If you are trying to install another ROM that has a huge system
Select partiton configuration as "data slot" and select an ID for the ROM
better to be a number
(It will be installed on data partition this means it will use the device internal storage space )
and select continue and set where to place patched file .
you can add more files to patch there .
and after you are ready to patch the files tap that tick button in action bar
to start patching
Step 4
After you patched the zip ROM go ahead and navigate to ROMs from the menu
select button down corner and select patched zip you patched
and then select keep location (or if you want you can change the location ) and add more patched zips or tap the up corner tick to start install
note : if any thing wrong happend PM me on telegram and send me multiboot.log in internal storage.
Step 5
after ROM is installed
it should be selected the installed rom .
tap and switch to primary rom
now use three dot on side of primary and select update ram disk
and then select reboot now
now after device rebooted go back to the app navigate to roms
now use three dot on side of new ROM you installed and select update ram disk
after it said done
select the rom you installed . ( tap on the icon of it or name )
( if you saw a message about checksum select continue )
reboot the device and see the magic !!!!
your new ROM is booting !!!!
Cool, let's stop enjoying and continue
Step 6
now after your new ROM booted
take your time to setup the device
and go and install dualboot patcher app again
now open the app
Go to ROMs and allow root access and
now use three dot menu in side of primary ROM and select update ramdisk
now use three dot in side of new ROM and select update ramdisk
and reboot
Step 7
now ENJOY your dual booted phone
for now on you just need to select the ROM and boot into it
it doesnt need updating ramdisk any more.
now go to the browser and navigate to this topic and leave a thanks
it helps to keep up the work

this post will be the ROM suggestions and combinations and screenshots
here is a video by @German Developer https://www.youtube.com/watch?v=ePRdE1OzRWE
my own best :
stock or motion as primary cm12.1 as other
app data sharing is on beta DONT USE IT TILL V2.1 . ( it make apps use same data )
any tw rom should be as primary to work ! this means if u want use any motion or motion based it should be in primary
THIS MEANS YOU CAN NOT INSTALL MOTION OR ANY STOCK AS DATA OR ANY OTHER SLOT !
You can install stock , and install motion on data BUT ! You will face RIL Problem .
with this intruction :
first install motion normally on the data slot,
note : you need 2 gbs space .
then install a custom kernel for motion rom :highfive:

Is the internal storage divided into two if there are two roms on you device? Like can 5 gb internal storage be utilised on each of the rom?
