Its no big deal, I actually like it more. Without adb, this wouldn't exist. Do you have Linux?

Maybe I can make a windows/Linux bash script that automates the process :)

And, just made this app, with reboot options, if you set SD marker option in the app, you wont have to do the commands :)

Will upload later, on phone ATM :)

yep, needed to go to my neighbors to download it:P

btw. could you tell me what you edited in ramdisk?

i want to try it with ics:)

edit: can the partition size be bigger than 1024?
[Xperia Play Android Development] KeiranFTW:
I modified init.rc, added dualbootme script under /sbin/ that is executed just after booting, and I also added a systemsd.sh script at /sbin/ also to be used to mount sd Rom system partition in recovery :)

Did it work then :)

hi,

i have one problem

I edited updater-script of cm7 but it won't flash in cwm

it is hanging on finding update package

what did i wrong
[Xperia Play Android Development] KeiranFTW:
Did you partition SD card?

Boot into recovery, then do:

adb shell

chmod 777 /sbin/systemsd.sh

./sbin/systemsd.sh

exit

Then do:

adb shell df > sdpart.txt

Then copy sdpart.txt content and post it here :)

thanks but i think this is no longer relavent as CM7 and stock need different kernels but it works.

Manually creating the ext2 partition worked thanks Kieran :)

Unfortunately i had to give up on this i have a dodgy USB port on my laptop (the only one left working too) and repeatedly got device not found because my USB port kept disconnecting the phone, i got as far as pushing the modified update.zip to my phone so everything after that should of worked.

Thanks again for this, will reattempt in a couple of days when i get more time

If you get adb devices and get device offline then phone will detect computer as charger, you must reboot both.

[Xperia Play Android Development] nickholtus:
which rom (sd or nand)?
[Xperia Play Android Development] fma965:
i havent even dual booted yet. i cant get darkforest to work with wifi? i am using the kernel on first post

download wifi modules in doomkernel thread

i have flashed doom lords modules was i suppose to do this? i didnt have wifi before i flashed them either.

for some reason my phone keeps going back to the setup wizard everytime i reboot my device.

just gonna start again from stock.
[Xperia Play Android Development] nickholtus:
did you flash dualboot.img?

Then keiran need to make a wifimodule.zip

btw. after flashing wifi modules from doomkernel it works here (wifi)
[Xperia Play Android Development] fma965:
yep but surely he has noticed he doesnt have wifi? if he has noticed he would mention in post that wifi wont work. maybe he has made modules but hasnt has uploaded them yet.oh well i can live without wifi for a little while got unlimited data. but how come my phone is going in setup wizard each time it boots?

well like i said just reflashed stock now so will see.

hmm my internal storage ses 0mb used out of 0mb
[Xperia Play Android Development] KeiranFTW:
WiFi fix: terminal emulator:

su

cp /modules/bcm4329.ko /system/lib/modules/

reboot

Setup Wizard fix:

You didn't push the ext2 data image, while in sd Rom:

adb remount

adb push data.ext2 /system/data.ext2

Then you should have working WiFi and data partition.

how long should the sdparted command take? it been like it for about 5-10mins.

can i partition it using the partition sd card option in recovery instead? as sdparted does not seem to be working.
[Xperia Play Android Development] KeiranFTW:
Yes you can, but this way you will only get a 512mb partition :)

the max size in recovery is 1gb though.

just gotta wait for my cm7 to download from the crapiest file hosting site ever. and rapid8 no longer allows files over 100mb so that screws that up for me. hopefully i will get it working this time ;)

this also doesnt work. no ADB commands work with this dualboot kernel or with v11 doomlord for that matter.

hmm well i am still getting 0b free in internal memory and i cant install anything. not tried the loading the second rom yet.
[Xperia Play Android Development] nickholtus:
i think you did something wrong then.

what did you exactly do??
[Xperia Play Android Development] fma965:
i have done everything exactly as mentioned. where is the system/data suppose to be located on stock rom? nand or sd? im confused :D
[Xperia Play Android Development] nickholtus:
/data needs to be on sd
[Xperia Play Android Development] fma965:
yeah but how?
[Xperia Play Android Development] nickholtus:
adb push data.ext2 /sd-ext/data.ext2
[Xperia Play Android Development] fma965:
Doesn't work. I managed to make partition via adb and then pushed data but it still said 0b free and was unable to boot second Rom.
[Xperia Play Android Development] KeiranFTW:
Okay, so next release will require two partitions ext2 partitions on SD, one for data, one for system. If you are getting 0b in NAND Rom, something's very wrong.

Sent from my R800i using DFR3.0.5 NAND + CM7 SELFKANG SD
[Xperia Play Android Development] ICXPlay:
ok,

then i need to buy a new sdcard:P

both on sd is nice (i tried it on the hd2 also dual boot)

i would try dualboot 1 more time (my phone won't flash the modified rom)
[Xperia Play Android Development] Therev86:
hmm, i have a spare couple of hours this morning and am reattempting this but today i am unable to get as far as yesterday, after flashing the dualboot kernel i consistently get "Error: device not found" in ADB even after restarting both the computer and the phone.. any ideas?

EDIT: probably worth mentioning under device manager it shows no ADB devices, just Xperia Play with the error "device cannot start"

And my SD card shows under "Storage" but internal memory shows 0.00MB free, and all that has been done is flashing dualboot.img.

Im off out now so im going to need to flash back to stock, will try again in a couple of days.
[Xperia Play Android Development] fma965:
i have tried this guide 3 times and always get 0b but if I flash back to v11 kernel it is fine. I think dualboot kernel not working correctly also the data.ext2 is on my sd-ext.
[Xperia Play Android Development] fma965:
yes but if the only thing you did was flash dualboot kernel then it would say 0b as the data.ext2 is not mounted.
[Xperia Play Android Development] Therev86:
Just a redundant observation, irrelevant too since i cant mount or partition the SD card in ADB due to the aforementioned error.
[Xperia Play Android Development] fma965:
try doing all the steps and then flashing the kernel just before you apply the cm7 update. thats what i did although i still never got past the 1st rom saying 0b and unable to type the commands to change to second rom.
[Xperia Play Android Development] sfex3best:
I keep getting this error from the sdparted command.
[Xperia Play Android Development] fma965:
dont boot the rom instead use the touch v4 cwm recovery 5 and type the command in via adb.

---------- Post added at 03:27 PM ---------- Previous post was at 03:26 PM ----------

so instead of using adb when the phone is booted boot in to a recovery and then type same commands in ADB.

[Xperia Play Android Development] Solar.Plexus:
I'm going to try this out tonight, will report back if I get it work.

How was Keiran able to boot DFR3.0.5 and CM7? I thought they required different kernels.

I guess what I'm asking is which ROMs are compatible with this dualboot kernel? My R800x is unactivated, WiFi only, so I'm not worried about anything CDMA related.
[Xperia Play Android Development] paxChristos:
CM7 Kernel can run DFR.
[Xperia Play Android Development] Solar.Plexus:
Ah alright, thanks pax.

To start off, I'll see if I can reproduce Keiran's dual boot then.

If you can't, I can't fix it, because I don't have enough time sorry.

[Xperia Play Android Development] nickholtus:
not possible
[Xperia Play Android Development] Leraeniesh:
Keiran, once you are done with exams, could you develop the dualboot kernel for AOSP ICS ROMs?
[Xperia Play Android Development] KeiranFTW:
Yes,

Maybe even more sensible method too :)
[Xperia Play Android Development] nscxp2005:
Keiran,

Can I ask when you exams finish?

22nd June.

I have a long break after the end of this month though :)

So hang tight :)
[Xperia Play Android Development] anbu187:
Why not possible? Please explain thanks
[Xperia Play Android Development] KeiranFTW:
WM6/6.5 closed source... you should know that...
[Xperia Play Android Development] Solar.Plexus:
Definitely looking forward to a solid dual boot. And just to confirm, there's no way to make a stock ROM/ICS ROM compatible kernel, correct?
[Xperia Play Android Development] anbu187:
Then how is it possible that there is a video on youtube about windows xp installed on an android phone? If we can dual boot windows and linux on a pc why not possible in android phone?
[Xperia Play Android Development] nscxp2005:
The video you will have seen on YouTube will be them running Windows XP through VNC not on an Android device itself.
[Xperia Play Android Development] anbu187:
How about dos emulator or something like that on adroid?
[Xperia Play Android Development] KeiranFTW:
Are you crazy? If I could code something like that, do you think I'd be developing ROMs and kernels?

This allows you to dual boot android, and android only. If you want to run windows on it rewrite the boot loader, implement a BIOS, flash the bootloader, enable USB OTG, plug in external CD drive, install windows, then you don't need a kernel to dual boot.
[Xperia Play Android Development] bamsbamx:
It doesnt seem to be very dificult.... Hahahahaha

Just asking questions don't be mad ok? Peace
[Xperia Play Android Development] KeiranFTW:

[Xperia Play Android Development] baari21:
Hey Keiran. I know your on exam and stuff but do you think it would be possible for you to get ics/gb dualboot running after your exam? I sent you a pm but I am not sure if it was sent because I cant find it in my sent messages lol.

Would this app help it to get running?

Maybe this app might make it possible: https://play.google.com/store/apps/details?id=com.drx2.bootmanager&hl=en

This is what it does: http://init2winitapps.com/stories/BMManual.html

I know with other tablets and phones they usually reboot to the secondary OS.

Well sorry for taking up your time and best of luck with your exams.
[Xperia Play Android Development] nickholtus:
yes, it will work.

i tried a ics kernel with a gb rom and it runs very good
[Xperia Play Android Development] bamsbamx:

I wish we could dual boot a gb and ics like cm9 or aokp that would give Sony a big we don't need you
