Hi mates. As far as I'm reading I consider that it's possible dual booting between any stock Sammy jb and CM 10.1.

All we need is just an updater script moddified for the choosen roms. I know it's not just as easy, but let's think out of it.

This is one of the most helpful threads around being a long time reading xda. -)

This was really helpful thread.

Thank you!

It is just to complicated with the new drivers to flash a different kernel for booting first ROM and other kernel for the second one each time.
[Galaxy S II General] Rene_ajax:
Thats weird, isnt it?

Also, what if I replace the seclauncher, framework AND systemui.apk in the rom .zip?? Is that the same or should it then work??

Ps. do you think dualboot is really necessary?
[Galaxy S II General] 911-Future_Maker:
It's not really necessary, but it's very nice option to us to explore our phones in many different ways. Example: I want stock, because some games are not running on custom rom, otherwise I badly need all the customization possibility of AOKP and than here it is dual booting. )
[Galaxy S II General] Troubadour666:
because of "many different ways"

hi all,

Fortunaly for me, it's because of discovering this <> way of using our S2 that i could so quickly learn and understand how is working my i9100 :) and have progress to sharing too, which i want.

it's one of the best way to test so many rom, but also, many thanks the all kernels devs, especially in my sens, DorimanX and GM, because without the dual-boot they include in, we will cryyyy :)

Have a good day.

2 Kernels are just a temporary solution.

Nobody NEEDS 2 Rom but, in my case, I just can't stand using Sammy all the time. So I use CM because I love it. But when take a ride on my racing bike which is 50-130 km each time I need a 100% reliable Phone, in 1st GPS of course.

For everything else I use CM.

But even the temp Solution with 2 Kernel we get the change to switch between both worlds without backup n restore each time. Plus we can flash any AOSP we want as 1st Rom without killing 2nd Rom files.

So, overall, it's not that bad to have it :)
[Galaxy S II General] Indio Tiki:

[Galaxy S II General] 911-Future_Maker:
Hey guys

ANOTHER DUALBOOT BREAKTHROUGH

I got to work as second rom!

Space & Time 2.6

That's awesome! And I said before this can be possible for ANY STOCK JB ROM and ANY CM/AOSP/AOKP.

The limit is only our imagination.Even now typing this from my new 2nd rom! Aah I was missed the stock rom XD. Listen up:

All I did was to relocate the preload partition to data/app/app and to modify update-script to correctly symlink the files.

No need for an LSD kernel nothing, just use any Dorimanx 7.44+.

My 1st rom is Resurrection Remix 3.1.3 running on Dorimanx 7.44 Regular Version not the modded LSD by Red Blur.

No changed kernel, no hardcore flashing, just a little fun with the scripts and directories. And all

that made on My S2, no PC used. I downloaded the Rom, than open in Xplore, edit it ,repack and flash!

2 roms are working flawlessly. RR was 1st rom, rebooted in cwm, wipe data/cache,dalvm for 2nd Rom, flashed the modded Space and Time

fixing permissions and RnR!

Come on give some feedback guys, everyone say Sammy+Custom Rom =Not possible, so

that's we are doing is a kind of a revolition.:D

I can't believe:I'm dualbooting Sammy+AOKP. wow

Plz excuse my writing mistakes if any- I'm so excited now. o_O

Tomorrow I'll contact the Spac and Time dev to give me permission to post the instructions to you guys

how I get it working!

THX DORIMANX FOR YOUR KILLER AWESOME KERNELS MATE!

Cheers: OoUH I need sleep. XD Hit THANKS to make me sleep better mates. )

Yeah success.

Just a 2 shots to view all is real:
[Galaxy S II General] jootanen:
Re: [28.02.13]Dualboot Samsung JB with AOSP based ROMs [GUIDES/VIDEOS/LINKS]

.zip that I downloaded doesn't have anything in framework and in system. There is just some files in meta-inf and .apk in preload. Strange that it doesn't make any symlinks

ui_print("");
ui_print(" Wellcome ");
ui_print(" dr30ma ");

run_program("/sbin/busybox", "mount", "/system");
mount("ext4", "EMMC", "/dev/block/mmcblk0p12", "/preload");
package_extract_dir("preload", "/preload");
set_perm_recursive(0, 0, 0755, 0644, "/preload/symlink/system/app");
ui_print("Installing files");
package_extract_dir("system", "/system");
run_program("/sbin/busybox", "umount", "/system");
ui_print("");

ui_print(" Thanks ");

Maybe try move seclauncher2.apk to /preload/symlink/system/app?
[Galaxy S II General] 911-Future_Maker:
Still no answer from the S&T dev guys... may be someone other should try talk to him /

Don't worry I'm starting to try all other famous stock sammy roms and report all the progress here.

btw Ou as I expected Real Racing 2 and 3 didn't run on RR 3.1.3, but the 3 is working nice on LS8 all on same kernel 7.44

Seems some games run only on stock rom.

Hello!

What do you mean by "modify update-script to correctly symlink the files"? I'm interested!
[Galaxy S II General] bombaybadboy:
Re: [28.02.13]Dualboot Samsung JB with AOSP based ROMs [GUIDES/VIDEOS/LINKS]

Normally update-script pulls apks from /preload/symlink/system/app to /system/app during instalation.

Modified updater-script changes instuctions during instalation, not tp pull from /preload but to pull from /data/app/app and install to /system/app

Example:- symlink("/data/app/app/AllSharePlay.apk", "/system/app/AllSharePlay.apk

So now apks can be moved to /data/app/app from preload so now kernel can use to dual boot

Hi,

i make a script which i flash after flashing the omega rom i modified without "symlink line" in the updater-script.

create_preload_symlinks script :

-----------------------------------------------------

#!/system/bin/mksh

cd /data/app/app

# Can't create array with /sbin/sh, hence we use mksh

apk_list=( `ls | grep .apk` )

odex_list=( `ls | grep .odex` )

items=${apk_list[*]}" "${odex_list[*]}

for item in ${items[@]}

do

ln -s /data/app/app/$item /system/app/$item

done

Came from user Sale i think, but it was originaly for \preload\ and i adapt it.

It makes automaticaly 'ln' in \system\app\ for all files you have put in your flashable rom , in \data\app\app\ i mean. perhaps it can be integrated in updater-script

Mounting DATA.IMG :)

The last thing i want is this.

I ask directly to Dorimanx and he gives me some instruction.

(i use putty to do this)

---------------------------------------------------------------

about mounting the sec rom data!

i have added auto mount to kernel script!

so in next kernel it's will be by auto from now.

if you want to test now.

using adb as su

losetup

this will show you all used LOOP devices.

see one that free (missing number)

then do this

mkdir /data_sec_rom;

chmod 777 /data_sec_rom;

losetup /dev/block/loop4 /sdcard/.secondrom/data.img;

mount -t ext4 /dev/block/loop4 /data_sec_rom;

ls -la /data_sec_rom;

i have used loop4 but if you see it already used then use other number!

then just go to /data_sec_rom;

and all files there :)

Have fun.

------------------------------------------------------------------------

Yes, i have fun :)

you have to see the result here in little tuto :

Amazing Mate but..

Isn't that mounted anyways? I mean, we have /data from .secondrom when we boot into 2nd Rom. Or does this mean we can access data of 2nd Rom from 1st Rom?

Sorry if that's a stupid question!
[Galaxy S II General] Troubadour666:
about mounting data.img (II)

When you are in 2nd ROm sure your data mounted are data.img and cache.img, the command are unuseful, but if you are in 1rst rom, you can access the data of 2nd ROM by this way because they are not mounted, in \data\ you have the datas of 1rst rom :)

understand? sory for my bad english tio explain :)

on my last youtube video, you see i'm in 1rst rom to do my demo, see the 2 build.pro i edit in, one in \system\ and the other in \preload\.

hope my explaination help you.

When i ask dori what i do with his losetup, he tells me that :

--------------------------------------------------------------

you did all right, well you dont have to unmount, its done by reboot, and files you change inside, stay.

about free loops, this is the way to see what free, but if you will move apps to sd, then loops will be taken, and loop0 will be used already.

its will be auto in next kernels.

---------------------------------------------------------------

interesting too :)

I use like this :

this will show you all used LOOP devices.

see one that free (missing number) ---------------> you have loop0 and loop1

by winscp, in putty for example :

losetup -f

(which show only the 1rst loop free device)

for the two way using losetup, do these commands above:

mkdir /data_sec_rom;

chmod 777 /data_sec_rom;

losetup /dev/block/loop4 /sdcard/.secondrom/data.img; (replace loop4 by loop0 or loop1)

i give a try .

so after long repacking and writing these lines :) , i have 100% succes with my flash, i think i have chance while making 'rapido' an updater-script because i made it with nowipe lol, no destruction of \data\app\*.apk and just changing all apks in \system\app\ and \data\app\app\ symlinked too :) (sh***t agaisnt the "script symlinker" that i cant have succes with integrate it in updater-script (because i'm so so noob :), just a supplementary flash :( nvm !

For information,

i implement dorimanx 8.3 the last and xxls6 modem which are the finest for my use, i think it's that this only way that we have to consider kernel, we have to find the most combination for our personal use, and Dori, for my personal use is the best, never desapointed :) and always good advice of use !

Also squeeze aroma and some softs in \indie\samsung\ like :

all the rest is in, redistributed in \system\app and \data\app\app.

Hope i give some info with this report of this test, always in 2nd ROM.

I can share if someone is interested to see the zip .

At all, have a good night.

No success with Biftor v6 and WanamLite roms mates...Biftor is showing Status 6 in cwm, wanam is loading forever. I know status 6 means problems with updater script, but I checked it a hungred times there are no errors there. I'm trying the way I'm running Space and Time 2.6 without changing kernel just install as 2nd rom. Can they run on Dorimanx 7.44? Or require some other kernel...Wanam and Omega also get installed fine without errors so the mods are working good, but when it comes to boot it just loads forever. For Omega I had used the posted updater-script by jootanen as the modded by me and the same result. Black screen at boot, only backlight buttons alive. Hey jootanen bro: Have you tried to run Omegav20 as second rom? Why Space and Time runs, but other as Wanam can't. Give me ideas guys. )

IF SOMEONE BOOTED THOSE ROMS AS 2ND PLEASE SHARE YOUR KNOWLEDGE. :D

Why using Root Explorer to create symlinks after flashing mate? This is an extra work. Just use the script below, save it as symlink_preload in Notepad++, then add it to updater-script and put it in your rom @ folder where the zImage, modem.. etc.. are.

Here is the script:

#!/system/bin/mksh mount -o remount rw /system cd /data/app/app # Can't create array with /sbin/sh, hence we use mksh apk_list=( `ls | grep .apk` ) odex_list=( `ls | grep .odex` ) items=${apk_list[*]}" "${odex_list[*]} for item in ${items[@]} do ln -s /data/app/app/$item /system/app/$item done

And just add this to updater script in line before flashing kernel and modem:

package_extract_file(""VARIABLE NAME"/symlink_preload", "/tmp/symlink_preload"); set_perm(0, 0, 0777, "/tmp/symlink_preload"); run_program("/tmp/symlink_preload");

Keep in mind your "preload apps" must be in data/app/app or script won't work and you'll have bootloop(probably). Also delete all entries in updater-script which contains preload/symlink/system/app/ because you don't need them when using the script.

Remember that booting rom first time takes about 5 mins
