Ok, I tried it:

Followed steps (along with appropriate wipe, format at listed places),

A. flashed 1st rom and 1toxx zip, booted into it and rebooted using system changer,

B. flashed 2nd rom and 2toxx zip and booted into 2nd rom. worked so far.

C. now, tried rebooting into 1st using system changer, and got 2nd's boot animation again, and got stuck in boot animation.

Tried an updater script modification, to see if thats where I've gone wrong, didnt work out, same result.

First rom was dovahkiin 1.1 and 2nd was slim bean (both old bootloader roms)

Gotta go to sleep now ;)

If anyone out here has the time, have a look at the logcat attached while stuck in step C (boot animation), if that helps.

Will have another look tomorrow night if the problem still exists.

Cheers
[LG Optimus 2x] spyrosk:
The problem in this ROM is that busybox is not working correctly because I think it's not installed with --install.

So fdisk was not working at all and it didn't change to the other part of system.

Finally I managed to make it work.

1) There were two busybox files, one in bin and the other in xbin directory.I moved the one from bin to xbin (I tried to install the xbin's first with --install but fdisk didn't work again)

2) I modified the updater script.

I did these changes: (- removed, + added)

.......

ui_print("checkpoint 6");

So I think you should check it.

I also accidentally discovered that 2048MB /data partition, on old bootloader, cannot be formatted under recovery so I will change it to 2000MB just to be safe.

I am attaching the updated gb-dual.cfg to replace the the existing in DualBoot_Partition-resizer folder.

Edit: attachment is only for version 4.5
[LG Optimus 2x] Prowler_gr:
Spyrosk, you are a champ. It worked like a charm.

Now I patiently await your updated dual boot-tool that allows splitting of the old GB system partition to 512mb+512mb.

In the meantime is there any .cfg or .sh (or any other file) that I can easily edit to achieve this - after first using you AIO tool to create a 1024mb sized APP partition?
[LG Optimus 2x] spyrosk:
It's not only the cfg file to edit, that would be easy with partition-resizer. Fdisk needs to know also the exact start and end sector of the system partiton for splitting and switching, so it's more cmplicated.

New version v4.6 is now uploaded

Changes:

512MB-512MB system partitions for both bootloaders,

Reduced data (to 2000MB) for old-bootloader (for the reason I described above)

Bug-fix for dual-boot remover (SystemChanger app wasn't removed).

Coming soon

An aroma-style zip to replace all 5 existing zips, making the dual-boot controling even easier.

It is on testing stage.

If anyone wants to help testing just ask and I will upload it.

Stay tuned!!
[LG Optimus 2x] :
hey, i just got it working, awesome work youve done there!

but i have a question. Apparently the solution is in the op but my english is bad and im not sure what to do at that point.

The first rom is pengus cm10 and the second is lg stock ics.

Now i need Gapps for cm10.

So i booted cm10, rebooted into recovery and what now?

flash the gapps and THEN flash Dual rom 1 to xx?

Or only flash gapps?

thanks in advance
[LG Optimus 2x] spyrosk:
Flashing Dual-ROM-x-to-XX is needed only if ROMx or its kernel change.

But it does NO harm if you flash it anyway.

Re: [HOW TO] DUAL BOOT for P990 & SU660 on BOTH Bootloaders v4.6

Wow, thanks bud :) actually I haven't read that yet, but will do right. I saw there are some problems dual booting ics for old bootloader......there were problems in v2, but my 1st thought was "that was working with a kernel from Harsh and it needed to be installed as rom1?" I think your doing great work with this, sorry, have been playing with an Arc S last 2 weeks so it's time to catch up your AIO now......but, a question: since it ain't possible to dual boot both bootloaders, what does it take to make a rom for the new bootloader to boot from the old btl?
[LG Optimus 2x] spyrosk:
We missed you mate!!

New toy to play? Good for you;)

No problem with dual-booting on old bootloader.

It was a minor problem with the specific ROM and is now solved.

As for your question, to make a rom for new-bl to boot on old-bl, the least thing needed is to change all the mounting points to reflect the old partition table (and most likely not only that), chefs and kernel devs know better.
[LG Optimus 2x] mitok:
Hi all. I can you help me? :) i have stock ics v30c with unlocked bootloader from this thread http://xdaforums.com/showthread.php?t=1923106 wich roms can i install as second rom on my device to use on dual boot with my stock ics v30c?
[LG Optimus 2x] spyrosk:
AFAIK there is no other custom ROM for the unlocked Stock SU660 bootloader.

and dual-boot does not support this bootloader yet.
[LG Optimus 2x] SREEPRAJAY:
buddies superskill and spyrosk,

more than the partitions, we need old and lazy minds like mine to start doing something better to get to the old bootloader from the new one...in addition to that a good reason and a strong one...... :p rofl
[LG Optimus 2x] rugglez:
Re: [HOW TO] DUAL BOOT for P990 & SU660 on BOTH Bootloaders v4.6

Changing mount point is only the beginning. Kernel needs to be recompiled, lots of changes need to be made in the ramdisk, some other files also need to be modified.

In addition, if one is porting a rom to a different bootloader, it is expected that some things may not work even after doing all of the above (like, when making the stock ICS rom for the old bl, there was no network signal and many FCs, after doing all of those), so these rom specific things need to be debugged too.

That's why rebuilding from scratch is preferred to porting a rom, since if you rebuild the Rom with changes on source files (like changes pengus made for cm10 to boot on different bootloader), it is expected to work directly. Of course that is possible only because of pengus's hard work to determine the changes to be made.

But unfortunately, some roms like stock rom can't be rebuilt so easily, so porting is the only choice :)
[LG Optimus 2x] spyrosk:
As promised a version v5.0 is coming.

All five zips used till now for enabling/maintaining Dual-Boot have been replaced by an aroma-style flash-able zip.

It is tested by me and our friend Prowler_gr (thank you mate).

I will update OP as soon as I have the SU660 version ready too.

For those who want to get rid of the 5 zips I am attaching here the DualBoot-Control.zip and the updated instructions.

This is only for P990.

Attention!! For the old bootloader it is working only on current v4.6 repartitioning with 512MB system for both ROMs.

[LG Optimus 2x] spyrosk:

Version 5.0 is uploaded and OP is updated.

SU660 package now additionally supports the su660 ics bootloader as well. Too bad there are no custom ROMs for this.

Enjoy!!

Thanks a lot for the awesome work! :D you rock

:) Installed MIUI as 1st, then ICS 4.0.4 CivZ_FLEX-ICER_Rev4.2, when I went back to MIUI stopped mid way, in the MIUI bootscren (has no bootanimation), I reflashed MIUI and dualboot-control and now everything is fine, can swich back and forth.

[LG Optimus 2x] mark_hatred:
Just got some issues here that I need to fix, after having a dual boot . I have SU660 , and done the setup with P990 layout, Installed Flex_ICER on 1st ROM and Optithrust by Jishnu for the 2nd. Now I wanted to go back to a single ROM setup, so I nvflashed back to SU660 ICS layout, but something's strange and it was never like before. Before, after nvflashing on a layout when you mount usb storage thru CWM itll ask you to format the internal sd card on first instance, and something is strange as the internal sd is write protected and in ext3 format. And I can see that the internal is not empty, so maybe nvflash is prompted to skip formatting internal sd or anything. So how can i get it back to the single ROM format and having back the same setup as before which is formatting internal sd after nvflashing a layout. Thanks for this excellent work spyrosk.
[LG Optimus 2x] spyrosk:
Afaik smartflash wipes data partition and maybe the internal SD also. So make a nandroid backup.

Though I am not sure what will happen to the double system partition that dualboot uses, I think it will not be affected.

In any case smarflash the bb only and in worse case you reflash the ROMs and restore the data partition.

Write back and report the results after smartflashing the BB.

I am not sure I understand the problem.

The internal SD is always formatted as ext3 by nvflash, but write-protected? I never had such issue.

which tool did you use to nvflash back to SU660 ICS?
[LG Optimus 2x] mark_hatred:
IntSD-MountFix did the magic, no problems now. Thank you very much sir Spyrosk! This is excellent work and I regret that I never used all of the features of your excellent AIO ToolKit before. This was like automated bash on windows, and shows how power scripts could be when done the proper way! Thank you very much :good:

Workarrounds to backup/restore ROM2 (or both)

I know this thread has been quite silent, but I'm trying to figure out a few workarround methods to backup&restore ROM2. I've been thinking mainly on these two:

A. First method (Step-by-step, flexible) [WORKING; used a few times ]:

a.0 You have your ROM2 nandroid backup (if not... ¿what are you restoring?)

a.1 From ROM1 go to Recovery. Do a ROM1 nandroid backup. Boot ROM1 and launch SystemCharger.

a.2 Enter Recovery (before or after booting) Restore ROM2 nandroid backup. Avoid rebooting system, or come back to recovery after.

a.3 Install-zip DualBoot-Control.zip. Update ROM2 (don't reboot). Install it again, enable dualboot.

a.4 Wipe actual ROM data (from DualBoot-Control.zip), wipe cache, wipe dalvik, format system.

a.5 Restore ROM1 nandroid backup. Update ROM1. Do whatever you want, you should be ready.

**If you want to restore both ROMs and you don't have ROM1 installed, you will have to restore ROM1 normally, boot it, launch SystemCharger, and then start the above described process. In this case I would recommend ultrafullwipe, i.e. repartitioning with AIO Toolkit. Then, follow normal steps for ROM1, normal for ROM2 untill you get to the "install" step. Then replace it with above a.2 to a.5.

B. second method (limited but easier) [CAN'T MAKE IT WORK YET]:

b.1 You have (or you do) a total backup with AIO Toolkit (this should be for ROM2, or both. Not just for ROM1)

b.3 Have (or do) a backup of ROM1 (unless you are going to install another)

b.2 restore the total backup with AIO Toolkit

b.3 Restore or install ROM1

***I'm thinking that as formatting system is needed for each ROM to enable DualBoot, maybe this second workarround is not posible

I started tryng these methods because I'm testing baseband-RIL-ROM1-ROM2 combinations... and would be useful to have some solid way to do it faster. If they work well, and if anyone is interested, I could write the complete instructions (with SystemCharger, DualBoot-Control.zip, AIO Toolkit, recovery instructions, etc...). Anyway... This is the best proof of my confidence on the unbrickable nature of this phone; I mean: partitioning, flashing baseband, dualbooting, backup-restore-restore-backup-install...??? This phone is crazy; and our devs are amazing people.

Remember data wipe must be done frome DualBoot-Control.zip... And I forgot it once... all over again. I'll keep trying to find adjustments to make second method work.

EDIT NOTE: After testing both methods, I've been thinking that maybe online nandroid managers (any of them) could do the magic too. For now, I'm not testing. Main edit is that I've detailed first method steps, and that second method is not working.
