Dual boot on LG Optimus 2X

Hey I was wondering if there is a way to get dual boot on my O2X. The type I would love the most is the one of this kind forum.xda-developers.com/showthread.php?t=1095658
But dual boot with any other system would be great. If anyone are able to make this happen that would be great. I myself have no idea how to make this work so help would be great. Thanks for your attention.

i don't think it's possible to do that
the o2x has 400MB of system ROM and most of rom uses up to 350MB, qhere do you want to put other roms?

Hi,
it's not a dual boot, but you can now launch a full linux system from android using the chrooting method, see here:

That is great

Im having some trouble with the installment of ubuntu though

They have hadded BT5 now that's real sweet to have with you on the go.

seems they are working towards native boot with usb host support that would be the golden price

the hdmi out is suppose to work on it, still havent gotten to test myself though

Anyone tried Bootmanager on O2X?

Dual boot is actually possible.But till my exams end i am not working on that Project.Till then enjoy my chroot images.My exams end on 22nd august.Will start working on Native linux booting after that.

I couldn't resist for €2, but the device is unsupported, so I have to fill in the the details manually. Such as:
- Device
- Sdcard block
- System size
- Data size
- Cache size
As soon as I see a chance to test it properly, I will report more.

Any news on this. I found this interesting but saw our device still unsupported as you have already mentioned. It will be wonderful if o2x gets supported. And the best part is not only dual boot but supports upto four/five including the ROM in phone.

Hi
Also looking for more info on this. Did you get it working in the end?

Now that so many different flavours of GB ROMs available for our device (CM with working A2DP & FM, MIUI-FM expectedly will be working shortly since CM has made it & STOCK ROMs) a Dual /Multi boot will make a great value addition to O2X. Hoping to hear something positive from you.

Its not exactly a dual boot...U will boot into android and then manually run the script in terminal emulator and run linux on top of Android..think of it as a virtual Machine...there will be no sound from within Linux..The android O.S will continue to function as Normal..There will be no effect on the Main O.S...other than Memory consumption while you run the chroot..ofcourse that is to be expected..

How to Develop Roms For LG GT540

As the topic says, i want to start developing or porting ROMs/Kernels
for the LG GT540 or any other phone.
I know a fair amount of computing and game developing. So can
anyone tell me what the requirements are for developing a simple ROM.
For example like how much RAM i need on my PC and need to learn Java c++ and etc.
I do know how to make an android app but couldn't put it in the market
as i need a license which i didn't buy. I don't know how to make 3d games
and stuff i can only make simple 2d apps.
I did read some stuff here:
http://developer.android.com/guide/index.html
http://source.android.com/source/initializing.html
and a lot more.
I know developing isn't easy but i do like technology and stuff like that,
so that is why i want to learn.
Thanks.

i think building ICS is a bit too advanced for me. Maybe requirements for
AOSP for building from CM sources?

It's good to have dual core processor and you must have more than 1GB ram (otherwise linux system will kill process, because he will don't have memory). And maybe 30 GB disk space.

Firstly you'll need C++ and Java. But that's not all. You'll need to understand the structure of the Android source and kernel and how they work. You need to know how to write your own device configs and makefiles. And you must know how to solve errors.
Your build machine should meet the requirements for building Android. On my machine, Gingerbread is ready for 2 hours. Here are my specs:
Intel Core i5 430M Dual-Core Processor 2,53GHz
4GB RAM
Ati Mobility Radeon HD 4570 512MB Graphics card
500GB HDD

I'm afraid I can't help, but I want to know!
I spent only 2 Weeks learning batch and html, so I'm quite clever. I'm currently trying to learn java, then will learn C++

i will try building Froyo as i think it will be easier and less system
requirements will be needed.
Also i am trying it make linux boot through a USB. will this be a disadvantage?
Or is installing linux as part of system better?

Lol similar specs!!! Just that mine is a i5 480M and has 1gb graphic memory
And no don't run from USB all settings wont be saved like wallpaper every boot resets everything

Is much simpler install ubuntu on hdd
if you build android on a usb you wil ran out of space
i want to learn too lol

I want to kill my phone so now dl'ing ubuntu and ICS sources.

How about installing on a virtual machine? It will may have lower performance (depending on settings) but installing on a hard drive isn't reversible.

[Guide] Building your own ICS ROM on 64-bit Windows 7

Please note that this is a guide to how to setup an environment to create your own ROM, and to build a test AOSP ICS Rom that will work on an emulator. While it is possible to do all this in 32-bit Win 7, you will find it much (!) easier in 64-bit Win 7. The intention is to allow all the folks who have said they'd like to work on a ROM to get their feet wet. If you complete all the steps in this guide you will have a Vanilla ICS Rom that works in the Android Emulator. You would still need to modify the kernel for the Tegra and add the special radio and other drivers before porting to the Streak.
Of course you can skip step 4 if you are willing to either dual-boot Ubuntu, or go into Ubuntu full time. However I figure a lot of folks on here are still on Windows for one reason or another.
1) Make sure that the ROM for your Windows 7 computer is set to allow Virtualization. If you have a Core i7 this will be the default. Otherwise you will need to make sure to set it manually through the Setup that should come up before BOOT.
2) Download VirtualBox 4.1.8
DL Link here for VB:
http://download.virtualbox.org/virtualbox/4.1.8/VirtualBox-4.1.8-75467-Win.exe
DL Link here for VB Extensions (necessary for USB, shared folders, etc):
http://download.virtualbox.org/virt...alBox_Extension_Pack-4.1.8-75467.vbox-extpack
3) Download Ubuntu 11.04 64-bit
DL Link here:
http://www.ubuntu.com/download/ubuntu/download
Make sure (!) to select the 64-bit version before clicking download
4) Install VirtualBox and Ubuntu:
Install and Setup Guide:
http://www.sevenforums.com/tutorial...ndows-7-virtual-machine-using-virtualbox.html
(Note that some of the images from this guide are from an earlier version of Ubuntu)
I personally recommend that as long as you have at least a Quad Core that you give your VB machine Two Cores and Two Gigs of RAM. For the HD size of your Virtual HD remember that the Android Source Code is almost 16 Gigs. For speed and other purposes I suggest creating a fixed size 80 Gig (or larger) Virtual HD. While this can be on an external drive, if you have room on an internal drive that will also improve performance.
5) Install the Toolchain (Android Build Environment):
http://mjanja.co.ke/2011/11/building-android-4-0-on-ubuntu-11-10/
The first three steps will take between 1-2 hours. Step 4 will take an hour or so as well. Step 5 takes multiple hours due to the size of the Android repo source library. Plan accordingly
Hope this helps!

Looks good, but its way easier to use a direct Ubuntu installation, dude.
So far as i can see, you can use the sdk on 32-bit, too.

Mind everyone he said this was for AN EMULATOR

And that it still requires tuning for the Tegra chip and the custom radios. This is not a new ROM, rather it is what you would need to do to setup an environment to create a ROM.Just saw so many folks saying they would like to help, that it seemed to make sense to show them how to get started. If anyone has gone through this and is ready to take that next step, this would be a good place to let folks know.

Support on 32-bit is "experimental" according to Google. As for a direct install, that'sonly true if you are ready to convert to Linux or dual boot. On a fast machine having the VM is actually pretty quick, and allows you to mess up without impacting everything else.

WINDOWS,UBUNTU on Android

Guys I am gonna share with you some information about porting Windows and Ubuntu on Android.I've tried Ubuntu and it works on my mini.I've also tried windows XP but as our mini has less RAM and processor it doesnt successfully boot up.SO Iwill recommend you Windows 95.
For Ubuntu:
Go to this link:http://www.androlinux.com
Download the zip and follow the video tutorial given there.
It will utilize your 2GB of sd card.After installing Ubuntu go to terminal then cd to sd card/ubuntu and give the command bootubuntu.Note that Android will be running in background so ubuntu will act as a Guest OS.
For Windows 95:[I've not tried it but it is for all androids]
Go to this link: http://www.youtube.com/watch?v=JWkqMmtSJRE
Thanks to opensourcegangster on youtube for the video.
Also file size is not large.Hope it works on our small mini
Still if you want to get Windows XP on android then follow this link:http://www.youtube.com/watch?v=EUE-gJmcGKk&feature=relmfu

screenshot ?

i believe its requires atleast 1Ghz cpu...thats our mini doesnt have...yes,maybe you can install ubuntu by ubuntu installer or windows with qemu and boot,but battery and cpu are forcing to do it and of coz there is a risk.....CMIIW

I've rubbed off ubuntu from mini.Forgot to take screenshot.Dont suspect it,I had tested it on mini.

i give u a clue, use non-chroot (it will run any unix with supported arm processor)
i use DSL as unix os (only 0.5gb) .
for windows, megh....! keep dreaming.
what the use for run win95 or 98, thats oldschooll OS, LMFAO!!!!

ROFL man, you make my day , if you are an average user you should know that windows xp can run on less specs devices; so the minimum hardware requirements are:
Pentium 233-megahertz (MHz) processor or faster (300 MHz is recommended)
At least 64 megabytes (MB) of RAM (128 MB is recommended)
therefore, if you're smart enough you can conclude that your statement quoted above are nonsense.(no offense here just my 50cent )

Android is built upon ARM architechture and also it's a MOBILE running XP.What do you want more than that?It is different from windows and also plz go to the link and see the video.I think you haven't.And also I had quoted that it requires more RAM and processor FOR AN ANDROID TO RUN WINDOWS.Windows 95 and ubuntu work on mini

Ubuntu is nice
But the windows 95 nahhhh

Linux instead Android

I had installed successfully UBUNTU with VNC but result was not one can use daily so removed in one hour, though good for experiment.
And our OB processor is not enough powerful you can throw Linux. Minimum requirement for UBUNTU is dual core processor.
Search UBUNTU on mobile, or UBUNTU;s official site.

cant we run win 95 ?

No.We can run linux because we can take android's linux kernel.Android is very low weight linux.

Win 95 can run alongside android but if u want to make it your native os u must work alot to port it.And in this thread i don't mean runing any os with android i mean runnning linux dis. instead of android.
