[W.I.P] Dualboot System.ext2 images Collection - XPERIA X10 Android Development

Hi All,
first up credit to Z for recovery and providing PoC of dualboot images.
I have worked on base image provided by Z and have removed most of the crap or not so necessary stuff keeping following thing in mind.
1) if we want to use 2.1 that's coz of its camera...
2) we need a basic features to be working on Phone.
I am right now testing this slipstreamed bare bone ROM will upload by tomorrow.
you can expect following from this tread
1) Collection of system.ext2 which you can use for various ROM.
2) Basic guide on how we achieved this size reduction.
3) Instructions + scripts on how to do the same in xrec .0.3 also.

Instructions to make it runable on Xrec .0.3
1) chargemon editing
1) open chargemon file
find "/system/bin/charger" line in it
replace the line with below code.
Code:
/system/bin/charger
if [ -e /data/local/tmp/dualboot ]
then
rm -rf /data/local/tmp/dualboot
sh /system/kernel/boot.sh
fi
Now your chargemon edit is done
if using adb push do remember ot set the permissions for chargemon again to 04755
i.e. chmod 04755 chargemon
now open the zip file of Z's dualboot..
copy system.ext2 to /system/dualboot/system.ext2
copy data.ext2 to /data/dualboot/data.ext2
copy all files from /system/kernel folder of zip to /system/kernel/ folder
now people here will to the very least post various system.ext2 which you can use as needed.
Once all files are in place you can write a simple gscript for dualbooting.
Code:
touch /data/local/tmp/dualboot
reboot
place this in gscript and add a shortcut on your desktop and you are done with the work.....
hope this helps

hey guys,
i have tried to convert existing ROM backups to working ext2 images... these can be made to work on the proof-of-concept as shown by zdzihu...
basically my aim is to be able to run ANY ROM inside ANY OTHER....
here is the first test release:
dualboot_DooMLoRD_MOD_rdannar_2.1.B.0.1 (for baseband 2.0.xx)
here is the second test release:
dualboot_DooMLoRD_BB67_EWJET_2.1.B.0.1 (for baseband 2.1.xx)

---

I really love to have dualboot but with xrec1.0 i could not.

---

I am really looking forward to this. Untill we get a full working camera/videocamera on 2.2 or 2.3 (i.e comparable with stock 2.1 camera/videocamera) this will be an excellent way to get the full functionality of the camera.
Thanks in advance for all your hard work

as of now there are some issues with it.... which will be resolved soon (hopefully) then i will release it for u guys to test

dualboot_DooMLoRD_MOD_rdannar_2.1.B.0.1
Since zdzihu wanted to encourage devs & users to switch to new xRecovery I am releasing this proof-of-concept as an Edify update.zip compatible with xRecovery v1.0.0… the concept being that we can convert ANY rom’s (nandroid/recovery) backup to dual boot image (yaffs to ext2 img) which actually boots!!!!
Also I am not saying that this is the only way but rather that this is the way I achieved it…
A BIG THANK YOU TO ZDZIHU FOR GIVING US THIS NEW TOOL TO PLAY WITH
all credits for the base 2.1.B.0.1 ROM goes to rdannar cause I have modded rdannar’s 2.1.B.0.1 ROM from:
http://forum.xda-developers.com/showthread.php?t=1109758
what is changed:
made it to work within ext2 img (dualboot)
changed baseband file to support baseband 2.0.xx
added JITv2
cleaned the ROM
fixed multiple busybox issues (there was one in /system/bin & /system/xbin)
removed redundant symlinks which were creating problems
added LauncherPro (I hate stock 2.1 launcher) & some tweaks for this app
added SpareParts & some tweaks
added some apps
Issues:
Currently there are some issues related to superuser (apps not getting SU permissions) [I think its related to integrated ramdisk in boot-stock.img] but I am sure that this can be sorted out with help from my friends
damn i forgot to change wifi.ko module so wifi currently might not be working
here use this: wifi-fix
just download it, extract it to some folder and use the following command to send it to the modded dualboot OS:
adb push wifi.ko /system/lib/modules/.
Requirements:
Baseband 2.0.52
Main ROM compatible with this baseband (I have tested this on CM7.1.0 RC0 J004 K012b)
U will need xRecovery v1.0.0 for this to work… Grab it from here: xRecovery v1.0.0 Installers for ALL roms
U will need 200 MB free on /system & 100 MB free on /data
How-to Install:
Reboot into xRecovery v1.0.0
Manually mount /system & /data
Go to main menu of xRecovery -> mounts and storage -> mount /system & mount /data
Flash this update.zip
Go back to main menu of xRecovery
Select “boot custom ROM/kernel”
ENJOY the speedy mooded 2.1 ROM!!!

Big Thanks to Z for this.
Here is my reduced size version of Z's 2.1
system.zip
http://www.mediafire.com/?62zacjq9dv2cq8r
data.zip
http://www.mediafire.com/?v3221o1uwufzc1f
unzip and copy directly to /system/dualboot and /data/dualboot after instualling Z's dualboot package.
system.ext2 -- reduced to < 130mb (I add 20 mb as spare so it's about 150mb)
data.ext2 -- reduced to 64 mb (need about 50mb at least)
Working on system:
- Alarm
- Browser
- Calendar
- Calculator
- Camera
- Market
- Mediascape
- Messaging
- Phone
- Phone Book
- Settings
- JITv2 included
@doom - buddy eagerly waiting for your yaffs to ext2 guide

cool work.... I am having something simmilar on my phone right now.... Albiet i have also removed Alarm, and calculator, will post mine by night @ IST.

Not got as much time as i thought today..but will see what i can do.
Just 2 questions to get me going.
I am using wolfs cm6 with his v007 test and the custom kernal from his thread.
if i put on the dual boot will this change my kernal again or will it keep the one i have. (i.e. I know it needs a custom kernal to dual boot but does it need a specific kernal or will any custom kernal do).
Also,
Which of the xrecovery 1.0.0 do i need
"2.2 ROMs (who dont require custom kernel by default. e.g.: FreeX10)
Please use the FreeX10-beta4-hotfix2.zip provided by zdzihu in the FreeX10 thread
2.1/2.2/2.3 ROMs
This is for those ROMs who dont require custom kernel by default but have the option to select custom kernel on next bootup.... basically the ROMs which use FreeXperia Recovery but donot boot custom kernel by default... or users who are using freexperia recovery to test custom kernels can also use this file...
xRecovery-1.0.0-rbt_test_kexec.zip"
The first one for 2.2 who dont require custom kernel by default. e.g.: FreeX10
or the second one for 2.1/2.2/2.3 roms?
EDIT: I just went ahead and did it...seems to boot into 2.1 fine.....will report back on issues later (Hopefully none)
Also, If i make a backup now using 1.0.0 am i right in thinking this should be a correct backup I can restore and it using xrecovery?
Finally just tried to reboot my phone i get a blackscreen that just says "Switched to fastboot mode..."
Any ideas?
EDIT 2: I pulled the battery and it booted into wolfs 2.2....Its looking good.

---

OK.
I have lost custom kernal on wolfs ROM. Is there any way to get that back and have the dual boot.
Secondly, When using adb to push wifi.ko to wolfs rom i get
cannot stat 'wifi.ko': No such file or directory
Any ideas?
EDIT.
I seeem to have pushed the file now but still get an error....also lsmod does not give me a wifi.ko listed..just the undervolt, twofish, dm_crypt and dm_mod modules....
I have even edited the hw config file to
insmod /system/lib/modules/wifo.ko
I really need wifi, otherwise I will have to give up on the dualboot

---

Sorry correction
you will miss your current kernel if you want to use your current kernel...
wait for some time i will post update on it.
