Seems to be working well. Running Gueste2X 3.6 and JB v4 both with default kernels:)

Like a tutorial? Or just showing how it looks?
[LG Optimus 2x] bihariel:
Well if you can make both, i really thank you. If not, only make a how it looks.
[LG Optimus 2x] Ajsh:
I will at least make one that shows how it looks if no one else does. but I don't have time today.
[LG Optimus 2x] bihariel:
there is no hurry, make it when you want/can.

Hello, how can I make this work for the G2X?

The thread

Thanks, I really want to try this. Also if it is not too much, can you still tell me if there is a general way to port roms and stuff from the p990 to the p999?

This is not the particular rom I want. I'll try cm7 + JB/ICS
[LG Optimus 2x] bihariel:
For rom porting, ask a user named dubnz in your forum who ported my miui 4 builds, he will tell you better.
[LG Optimus 2x] bihariel:
Hey here are the files you need:

NVFlash_Partition-resizer-G2X.zip - 22.52 MB

Dual boot O2x - v2.zip

So follow my guide and report back if it works.
[LG Optimus 2x] Rafase282:
Thank, I'm setting everything up, also I want to use custom kernels, they will be the same from update to update but are not stock. Is there a way to set it up before I start flashing zips? like incorporating the files into the zip?
[LG Optimus 2x] bihariel:
If they are in boot.img you can incorporate them.

Enviado desde mi Optimus 2X usando Tapatalk 2
[LG Optimus 2x] Rafase282:
They are zimage files and a bunch of others files along with the zip. I knwo how to put the gapps inside the rom before flashing but not kernels.

This would be for rom2 which is going to be JB

This for rom1 which is goign to be the latest cm7
[LG Optimus 2x] bihariel:
Flash the rom boot it install kernel and then extract the boot.img as said on first post.

[LG Optimus 2x] Rafase282:
Thanks a lot, it seems to be working fine. The only issue so far is that I had to edit the scripts to change the reference from p990 to p999 because it wasn't allowing me to flash them without those changes.

I had to reflash rom 1, after it boots I will check that rom 2 is intact.

Yeah, I can go back from one to another no problem.
[LG Optimus 2x] bihariel:
Good, now you can copy my guide to your forum if you want.

i have problem using nvflash

i have a problem using nvflash method, i have downloaded nvflash tryed on win 7, nvflash completes perfectly then when i hold down volume + key and power on the phone it doesnt goes to recovery it goes to software update mode, tryed many times but no luck :crying:
[LG Optimus 2x] SuperSkill:
To me your answer are in your post...for you mate, answer are in first post ;)

Edit: Ok, look in your previous post...

?" nvflash completes perfectly then when i hold down volume + key and power on the phone"?

Volume + and power = SW

Volume - and power = CWM

Volume + & log - = NV
[LG Optimus 2x] hellraiser:
now i reflashed to stock rom using nvflash its works perfest but when i trys to flash using downladed nvflash from first post its doesnt works, plz guide me to dual boot my 2x.

My phone has a uniq problem

hi guys i need help urgently, phone has a very anoying problem i cannot flash any cwm, if i flash a rom using nvflash method, and then flash cwm, and when i power on the phone with pressing volume key it goes to sw upgrade mode, then i downloads rom manager from play store install cwm when i chose option from rom manager to boot in to recovery it boots in to cwm recovery, but when i manually shutdown the phone and trys to boot the phone in to rrecovery while pressing volume - key its goes to sw upgrade mode, i also checked my volume keys both are working fine, can any buddy help me.... :fingers-crossed:
[LG Optimus 2x] bihariel:
You have to do this right: flash the nvflash resizer via nvflash and please when nvflash finishes let the phone rest 30 sec before unplugging your usb cable.

then unplug, put the battery back and press and hold volume - and power button and keep them pressed until you see the cwm recovery.

if this do not work, please use smartflash to flash a stock firmware.
[LG Optimus 2x] sane?:
Can I just get something straight?

If you install two different ROMs you also have two different sets of apps as well?

And both these ROMs are on your internal 'disk' space, so effectively you have half the space available?

So data tends to go on the SD card?

How do two different copies of the apps react to having two potential sets of data from the two different OS copies?​
[LG Optimus 2x] SuperSkill:
You have some folders named xxxx-1 and xxxx2,they have own apps, but share the partition for data...
[LG Optimus 2x] bihariel:
Correct, they share the partition but not the apps data files.

[LG Optimus 2x] Trystan34:
Can I restore my apps with titanium or do a nad restore on rom 1?
[LG Optimus 2x] Ajsh:
Don't see why you shouldn't be able to restore apps.

And the answer to your second question is in the OP
[LG Optimus 2x] MisjudgedTwat:
alright, using this now. i guess it works like it should, but... i dont get the point.

i am able to have 2 system partitions now, but not to have 2 data partitions, am i getting this right?

so when i switch the rom, my data partition will get lost, and i have to restore my data out of a nand backup, if i want to keep the settings and apps of each rom installation.

so, whats the point? i would have the same amount of work by doing it by using 2 different nand backups without losing space of my internal sd.
[LG Optimus 2x] SuperSkill:
The point is to have 2 roms installed, p.ex one stable with the regular apps and one for testing and still keep your regular rom. The two roms don't share the apps, only the partition. Inside some folders are now named with xxxxx-1 and xxxxx-2. For me this is great as I don't have to remove my regular rom(not a fan of restoring backups) when I wanna test another and I don't have like 250 apps either. Another point are the camera functionality, keep a rom with all camera functions and switch if it's needed......It's supposed to be an easy way, but no one are forced to use it :)
[LG Optimus 2x] Ajsh:
Even you need to read the OP:P
[LG Optimus 2x] bihariel:
Please watch the great video made by Ajsh on the first post, it is really easy how it works, you just click switching and the second rom boots with all its apps and configuration, you won´t loose any thing, when you are on ROM2 and switch again ( with a simply click) you will be on ROM1 configured like you left it before switching to ROM2.

i am sorry if you did not understand me, i am not English and i don´t speak it well.
[LG Optimus 2x] SuperSkill:
He just didn't see the point in dual boot, but we do :D
[LG Optimus 2x] MisjudgedTwat:
i got how it works, i just dont see any advantage in it.
[LG Optimus 2x] bihariel:
Simply, now i have a miui gb rom ( on ROM1) with everything working and configured, i use this rom as a daily driver. and i have on ROM2 miui jellybean with some bug and no camcorder. well whats the point of that? i like trying new roms and that was a problem because when i want to try a new ROM firstly i had to make full nand backup of my current working ROM ( everytime i want to change rom, i had to do it), then flash the new one and if i don´t like it or it didn't work well, i had to restore the nandbackup, etc....

Now with dual boot, with a simply click i can switch to ROM2 and flash whatever i wan´t without making backups or so... if the new rom do not work like i want or the camera not working or something like that, i only need to rum system changer, click switch and i am back to ROM1 as i left it already configured and with all apps installed....

Of course this feature don´t have to be useful for everyone, what i know is that dual boot makes my life easier and for at least 67 person who voted on the poll.
[LG Optimus 2x] MisjudgedTwat:
wait a sec...

this is not working for me. when i "switch the system" the whole data partition gets wiped

in that case i am sorry, maybe i did something wrong. i will repeat all steps again.

thanks.
[LG Optimus 2x] MisjudgedTwat:
alright, i got the point now.

my bad.

good work!
[LG Optimus 2x] bihariel:
why the data partition gets wiped? thats really strange, did you do the resize steps well?

It is working now for you?
[LG Optimus 2x] MisjudgedTwat:
yeah, for me the data partition got wiped all the time, thats also why i didnt see the point.

but now its all good!

i did it again and now it works like it should. its great.
[LG Optimus 2x] Trystan34:
Thanks. I did the restore from nand and it's working great but not sure if exceeds the size. I don't think it matter though becuase every thing seems to be working fine on both roms.
[LG Optimus 2x] bihariel:
Don't worry about size of your are using V2, there are no Roms bigger than 370mb, that's why i updated to v2.
[LG Optimus 2x] bihariel:
Good to see it us working now for you.

Ya i have the latest version of Benee Hackfest JB CM10, when i flash JB without jbapps its work perfect i can switch roms, but when i flash JB CM10 and then jbapps i cant boot in to ROM1 its stuck at LG logo :confused:, i think while flashing jbapps i saw its mounting partition then fixing permission after that problem starts. :fingers-crossed:

I can confirm that it should work. I just flashed JB gapps and switched back to gueste without any problems. But I don't know what's wrong in your case.
[LG Optimus 2x] Chris4evernoob:
First time I trued this it went perfectly smooth.

I flashed temasek 135,restored nandroid backup and flashed and tonyp's PA JB 2.1 as second rom.

Then I flashed latest Harsh kernel on JB and replaced the boot.img. I switched to CM7, quickly flashed the Dual-ROM-1-to-XX.zip and then flashed latest Etana kernel (low OC : 1.2ghz).

I booted up, replaced boot1.img, switched and flashed Dual-ROM-2-to-XX.zip

I switched back to CM7 as I was gonna use it as stable but now I seem to have lost root access : Root Explorer hangs, System Tuner won't change CPU speeds and Titanium Backup gets stuck on "asking for root rights.

I tried flashing superuser 2.3.1 and 3.2 (android.su/superuser) but I still can't use any of those 3 apps.

Is this just a ROM problem and should I just do a full wipe, redo the whole process but nandroid restore?
[LG Optimus 2x] SuperSkill:
You should stick to harsh kernel if you want JB rom included in dual boot, imo I think more kernels will support dual boot as time passes, but only devs can confirm it. I also recommend to set JB as rom2 to be sure both roms boot. It's been confirmed to work this ways in previous pages :) I don't use JB, but i read every post ;)

is there a way to convert a rom in a different thing or something like that ? I'm not good with dev stuff, I just apply what I see ^^

Try harsh kernel for paranoid rom :) report back please...

thanks.

I tried it. same thing happens :(

Even tried to put v20s as rom1 but its not booting, so cant access to apps to open switch app.

edit: ok so I tried with cm7 gueste hybrid 3.7 rom combined with paranoid cm9 and it works. but I really wanted to have a rom stock. I'll see if the battery is still good coming from a single paranoid cm9 rom, with this dual mod.

Would it be enough to change the partition table file to get ics values and change bootloader?

Sent from then win...."ME"
[LG Optimus 2x] spyrosk:
If the only thing is changing the scripts it could be easy, but If we need a modified recovery and/or bootloader (and I am afraid we do) It won't be that easy.

It somehow has to seperate both /system(s) on the same partition and tell device which /system to use every time (If I understand it correctly).

And of course we would need bihariel's guidance.

Happy 2013 everyone. !!!

I am sure with you guys joining and with guidance from other penguins..... :P and other good guys....

We will make it one more time

O2X with Magical ROM and supersonic kernels from my buddies
[LG Optimus 2x] bihariel:
it would be enough with that, you just need to increase system partition size so you have 512mb for ech rom and also you need to modify the scripts to fit the new sizes. i´m not sure at all but it should work.
[LG Optimus 2x] spyrosk:
Thanks for info bihariel.

So no need for modified recovery or bootloader? that's good news.

I'll take a close look at the scripts and see.
[LG Optimus 2x] bihariel:
you don´t have to modify any bootloader or recovery but on the nvflash resizer you have to use the new ics bootloader and new ics recovery, also you need to use the new ics partition layout *.bct. for the resize option you can also use the new method ( fuse or something like that).
[LG Optimus 2x] spyrosk:
Of course new ics bootloader and new ics recovery,

I meant any modification in the existing unlocked ICS bootloader or existing ics recoveries.

Thanks again.

(sorry run out of virtual thanks for today)
[LG Optimus 2x] bihariel:
yes,you don´t need to do any modifications.

When I was running Samsung stock based ROM, I used the RF Band menu to force the Modem to use only 850, but with CM9, I can't find this option.
