[Dualboot] i9082 {Stock 4.2.2/AOSP 4.4.2 and AOSP 4.4.2} 23032014 V2

k2wl · Mar 24, 2014

Hi guys,

finally I found a way to make dualboot on our beloved i9082 working!!

This way isn't as much easy as on other devices like the desire HD where
you have just to install an app and everything is done by itself, so follow this
guide at your own risk!!

THIS IS WORST RISK YOU TAKE FOR YOUR PHONE>>>>
IT MAY BRICK YOUR PHONE.....
DONT DO IT IF YOU DONT KNOW WHAT YOU DOING...

How to dual boot your I9082...

1. Make a backup of your internal sdcard to your PC!! All your data on the sd card will be gone!
2. Reboot to cwm-recovery
3. connect your phone to your pc.
4, open up cmd or a terminal and type:

PHP:

adb shell

5. type:

PHP:

cd /dev/block 
parted mmcblk0 
print

This looks like following

Code:

print

Model: MMC M8G1WA (sd/mmc) 
Disk /dev/block/mmcblk0: 7818MB 
Sector size (logical/physical): 512B/512B

21      3409MB  7813MB  4404MB  ext4         data

The last partiton i.e data partion which is our internal SD card to be re partitioned .

6. Type

PHP:

rm 21

7. Note the start and end of the data partiton. In my case its 3409 and 7813
Firstly we have to create data partition. See the size of system partition i.e 1024 MB. So the new partion will be as follows

PHP:

mkpartfs primary ext2 3409 4433

second is system 2 partition

PHP:

mkpartfs primary ext2 4433 6044

next is cache2 partion

PHP:

mkpartfs primary ext2 6044 6744

next is data2 partion

Code:

mkpartfs primary ext2 6744 7813

Code:

quit

It will say

Code:

quit
Information: You may need to update /etc/fstab.

Ignore the warning Reboot into recovery again on pc type

Code:

adb shell 
mke2fs /dev/block/mmcblk0p21 
tune2fs -j /dev/block/mmcblk0p21 
mke2fs /dev/block/mmcblk0p22 
tune2fs -j /dev/block/mmcblk0p22 
mke2fs /dev/block/mmcblk0p23 
tune2fs -j /dev/block/mmcblk0p23
mke2fs /dev/block/mmcblk0p24 
tune2fs -j /dev/block/mmcblk0p24

This will create ext3 partition from ext2

Now convert them to ext4

Code:

tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p21 
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p22 
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p23 
tune2fs -O extents,uninit_bg,dir_index /dev/block/mmcblk0p24

Now lets check everything is ok

Code:

  cd /dev/block 
parted mmcblk0 
print

This should look like following

Code:

print 
Model: MMC M8G1WA (sd/mmc) 
Disk /dev/block/mmcblk0: 7818MB

24      6744MB  7813MB  1069MB  ext4

Then

Code:

quit

~~Now flash your first stock ROM..ofcource custom one from recovery.~~

Now You can flash your desired AOSP rom as primary and dualboot enabled secondary rom.
Scripts to switch roms has been updated.

Download following dualboot enabled AOSP rom by me CosmicCm

http://www.androidfilehost.com/?fid=23329332407579496

Download following tool kit and extract on your External sd card for AOSP rom and in Internal SD for your stock rom.

http://www.androidfilehost.com/?w=files&flid=12981

Install smanager (os.tools.scriptmanager-1.apk) in zip.

Instructions on ROM switching:

1. Go to Play Store and install SManager (or included in dualboot-k2wl-V2.zip)
2. Run SManager, browse to your DualBoot folder and select "StockPrimary.sh/AOSPprimary.sh" or "AOSPSecondary.sh". depending upon which rom you want to boot into.
3. Mark favourite and su options and run the script.
4. Optional - SManager has a homescreen widget system. It lets you add buttons in your homescreens that will directly run the linked script (it has to be put in favourites first).

AGAIN this is a nuclear level risky procedure and is for ADVANCE users only....
DO NOT TRY IF YOU DONT KNOW WHAT YOU ARE DOING.......

Bugs:-
Your data partitions will be small about 1 GB.
External SD card not working in stock rom.

More?>..... You telll me...

HAPPY FLASHING.....

Does this method works with only cosmiccm ROM or it works with all aosp based ROM ?

Right now only CosmicCm but if developers willing for making their dualboot compatible rom, it wil.

Look into the second post...
reverting changes...

himuslg123 · Mar 18, 2014 at 4:55 AM

thanks for the tutorials k2wl

but I have a doubt

suppose ..I have installed 2 roms

now if I want to flash a mod zip( i.e pagapps or so) file for a specific rom via CWM recovery ...ll they be installed on a specific partition for a specific rom ?

k2wl · Mar 18, 2014

for second rom its a problem, i.e AOSP.
thats why i included gapps core in CosmicCM dual boot rom.
for original primary rom stock, you can flash any mods you want.

Give me links for the mods and gapps you wanted.
i will change them into dual boot...

himuslg123 · Mar 18, 2014 at 5:26 AM

aahh ..that's all I want ..you rock \m/

Well ..first thanks for this procedure..the more i thank u , the less it would be mahn!..
Now, as u say that u will help guys for mods to dual boot too, the only thing i flash after ur roms is ur kernel

... I dont think its already in there in cosmic rom,And cant live without evolution kernel mahn :|..but i think kernel flashing will screw things up right??

k2wl · Mar 18, 2014 at 5:32 AM

yes it might screw things up..
bt dont worry i will add option for evaluation dualboot kernel soon.
this is work in progress.
will add more options...

general question plss..y kernel is not put as a default in ROM( I mean ur kernel and ur ROM).

Though it will not allow users of RR and carbon to use this kernel. just of curosity

wiryawang · Mar 18, 2014 at 5:49 AM

Any possibility for a GUI apps or flashable zip to do all this procedure of dual boot in future development? What I mean is like GUI apps of EFS backup
