DualBoot 4.1.2/4.4.2 (in this order its better to test 4.4.2 roms)

Hi all dualbooters :)

actualy dualboot i have :

NeatRom 5.6 from [MENTION=3690986]_Sale_[/MENTION] in 1rst rom (excellent 4.1.2 Rom installed as explained in this thread)

all KK 4.4.2 ROMS i want in 2nd rom !

Kernel [MENTION=2376110]dorimanx[/MENTION] last Beta 8.43v64 version from this thread :

Never forget kernel is still in beta , and this purpose is for dualbooters that they know what they are doing with their phone.

Switching kernel like i do is not recommended without minimum knowledges and one day its possible i will brick my phone too !

so be verry carreful when apply this post.

Need :

- WINRAR to use my patches

- you must have dualboot already enabled on your phone, and DorimanX kernel already installed before use my patches, dont ask me how to dualboot . there are much threads about that now :)

Method : (what the content of patch)

- even kernel never been flashed when we flash in 2nd position, i change 'kernel boot.img' in ZIP ROMs with DorimanX 8.43v64 (actualy) zImage renamed boot.img.

(for your information, if you have a dualboot with two 4.1.2 rom, you already have 8.43vXX installed so you can use my pach to flash in 1rst position)

- I change MALI version in ZIP ROM with MALI V2 pack for dualboot with DorimanX 8.43vXX published on this thread,

(thanks to [MENTION=4704050]nik60[/MENTION])

- each updater-script from each rom has been reviewed.

When i flash in 2nd rom, i always :

- wipe dalvik 2nd rom

- make nandroid of 2nd rom (gain more space with wipe dalvik)

- format cache and system 2nd rom

- flash the modified zip rom in 2nd rom

You can see in my YT channel all sorts of KK 4.4.2 roms i find for our precious and i try to install following this method , :)

You can here find my patchs i published to download and drag and drop in KK 4.4.2 ZIP ROM you find and want to try in your 2nd rom.

ADDONS :

- About Nandroid backup your 1rst rom with DorimanX kernel, never forget that backup take /preload/ partition during process as sd-ext.ext4 files in your /sdcard/clockworkmod/backup/xxxxxxxxx/ backup folder. This /preload/ folder backuped is /system/ partition from your 2nd rom. Have to know that in future, when you will restore this backup, /system/ partition from your 2nd rom will be scratch and 2nd rom can have some trouble to boot :) , you're advised.

to avoid that, you need to edit nandroid.md5 file in /sdcard/clockworkmod/backup/xxxxxxxxx/ backup folder and delete this 2 (red) lines :

41cd6872f85cb7e83797817dd662403f .android_secure.vfat.tar.a

and delete the two files sd-ext.ext4.* in folder.

when you will restore in recovery, you will have an error because process search sd-ext to restore but restoration will be OK.

Cloning ROMs is one of the best solution to keep rom you want as 1rst rom or 2nd rom.

Dont mistake about DorimanX version kernel you will use. You have to use DorimanX branch 8 for 4.1.2 Rom.

Other method:

I you want to dualboot two 4.4.2 roms with dorimanx kernel, you certainly have to use branch 10.43vXX.

Imagine you have a KK rom without dorimanx kernel installed and without any dualboot.

you can :

On your TEL :

- flash dorimanx kernel 10.43v64

- reboot your phone and see if all is OK

- reboot in recovery , go to dualboot menu

- initiate 2nd rom

- clone 1rst rom to 2nd rom

- reboot your new 2nd rom (identic as 1rst rom)

ON your PC :

- open New KK 4.4.2 ZIP ROM you want in 2nd rom with WINRAR , delete META-INF folder !

- replace boot.img in New KK 4.4.2 ZIP ROM you want in 2nd rom with DorimanX 10.43v64 kernel zImage renamed as boot.img you have extracted.

- take one of my patch coresponding with your new choice of 2nd rom

- extract my patch

- drag and drop only META-INF folder (totaly) from my patch in your ZIP ROM opened yet.

- close WINRAR

- copy new finaliez ZIP ROM in your tel as usualy

- flash New KK 4.4.2 ZIP ROM modded in 2nd rom.

- reboot your new 2nd rom, it will be ok.
