I just read in the XDA Portal that someone found a way to dual boot between two different Android Roms on one phone and ,well...i was wondering if this is possible with Windows. i have Miri N Dinik's Rom right now but say i wanted to try out Energy's Rom too...but keep my previous Rom. Is that doable or is there something special in Android phones that makes it possible?

Thread moved to Q&A
To answer your question no its not possible to dual boot between 2 WinMo Roms. Android runs of partitions so you can install an Android Rom on different partitions and then select which partition to boot from. WinMo doesnt work like that.

oooohhh o.k. thanks ! i need to hurry up and take these IT classes to further my computer and systems knowledge. January can't come soon enough. iv'e learned so much from just this site alone though..i think i'll have a bit of a head start when i do start class.

Just use xda as your reference guide and you will do fine lol.

Since SDE was released, who wants to build some fresh and shiny android which might be running someday side by side with AVOS (Archos Android)?
What do we need (openembedded?)?
Installation of Other OS:
root: /mnt/storage/rootfs.img
kernel:
Reboot into Recovery Mode (howto)
Recovery System -> Developer Edition Menu -> Flash Kernel and Initramfs
Connect USB and copy "zImage" and "initramfs.cpio.gz" to the Archos
Unmount Archos on PC (safe remove)
Press ok on Archos
Don't you think dev's are already working on this right now?
OpenAS is a site to look at, there are a few in fact and some even on XDA.
your instructions are sort of nothing anyone who has booted the angstrom distribution can see that?
this thread is a bit pointless. your asking for devs to create something they are already working on and you can't help as you don't know how?
no, you just missed the point. I AM (or want to be) a dev, see my other thread about dvb-t support
and now I'm looking for some help and informations.
this thread should be dedicated to building gen8 android (2.2 / 2.3 / ...) roms, I don't care much about angstrom.
I'm not one of those annoying guys who just complaining about others work, I want to get my hands dirty and do some work! I already checked openaos out, there a lot of informations about gen6 and gen7 but not gen8, this is why I started this thread here.
summarizing informations, that's the point.
ok fair enough
it's more likely though someone will do a port and use it over the current android system as apposed to using the SDE. Most dev's will be concentrating on other O/S's such as Ubuntu etc.
I can see why you want to do it but im not sure it will be done this way. We havent even managed to get perm root yet, sadly the archos wont get a lot of love I fear.
we have perm root, just use SDE and put an android in it we can decide everything
edit: either you hack the gen8 and get rid of SDE and archos' android and put whatever you want on it or you stay with SDE and dual boot (sounds a less "brickable" choice to me)

Don't let anyone tell you you can't do it (whatever "it" may be). Any contribution to making my A70 better is a + in my book.

But it's pointless having android 2.2 / 2.3 running alongside android 2.2 / 2.3
it would be a complete waste of time especially as archos are currently working on it anyway.
It would achieve nothing, the SDE would be much better used running ubuntu/winxp or other, running android as a secondary boot option is a waste of development time and I cant see anyone wanting to do it?
by all means join in getting a good distro to run but not another version of android when all we are missing is root anyway. I think your getting confused as to what SDE is used for.
why would someone want to run ubuntu on this hardware? winxp is out of scope as it doesn't support arm processors.

why shouldn't we have root in SDE?? The SDE is the only way (so far, gen8 hasn't been hacked yet) to get perm root and custom roms.
why won't you just use SDE to run custom android roms? why it has to be ubuntu or any other bloated linux distribution?

no it's not, because archos won't let us do customizations. it would be easy for archos to let us perm root everything but they won't. so what are you going to do to make android comfortablier and less buggy on gen8? a) hack it and flash custom roms and may brick it or b) use sde and flash custom roms without the possibility to brick it

Agreed, who cares if you have more then one build of Android on a device? On other devices people have developed their own method of doing this exact thing. SDE is a great idea to let people load custom ROMs onto their device without fear of bricking. Now if someone would just get one developed....

Archos have released the source code, the only thing that's missing is Root.
The distro is already pretty close to stock even the BT stack is android native allowing us to use wiimote etc.
Archos have done a pretty "pure" android release Cynogen's goal is get a pure android rom working. Stock it's not that far away now?
and what about ISO, windows 7 (mobile), tiny linux, yellow dog, many other great distro's. All im saying is wait until root is achieved (it's being worked on) nd see what happens to the default android then.
Your may be jumping the gun a bit developing something that's not needed

was agreeing with you until this post.
the point is that Archos have up until now done a bit of a shoddy job of their Android builds. We all want the archos tablet running smoothly and as best we can and also would like to have 2.3+ on our devices which is probably unlikely by any official means.
and saying archos are "currently working on it" is a little silly given what forum you are on! (whats the point in people making custom roms for HTC devices... HTC are working on it anyway?!)
@wazalotofzeros
oh come on, are you kidding me? why is it so hard to understand that a rooted android or even custom roms are wanted by a lot of archos users (see archosfans.com)
whats the point of installing any linux distribution instead of android?
why are you telling me its pointless to do custom roms for the Archos Gen8 while there are custom roms for a lot of other android devices?
I give up, please contribute something useful to this topic or stop posting offtopic.
@waz000000,
don't want to participate in this then don't. There is no reason to put down others work though just because you think it is pointless.
Grand Idea
Personally I think this is a grand idea. At first when I saw the SDE I thought that was its whole purpose and that archos would start us off with a basic android version. But when it was released and it came with a barely working linux distro, it turned me off to installing SDE until something better can happen. I wouldn't mind seeing a micro version of ubuntu running on this, but the main problem is going to be the ram. If we are having issues with the ram on android what makes you think we will have better luck on a OS that wasn't intended to run on the archos. But hey more power to you. But on the other hand if we can build our own android firmwares, then we won't be dependent on Archos to decide whether or not to update to the next firmware. And saying Archos is working on it is like saying well the end of the world is coming. When IDK, but its coming!
Seriously. The delayed the launch by 2 months and then didn't deliver on their promise of launching with 2.2. They did come through, but with the crappiest 2.2 firmware I have ever used. Constant crashing, no wifi N, 200 mhz decrease in speed, and only a promise to fix it... eventually.
So the the OP. Go for it. I will help with what I can, but I haven't build a firmware yet except for the easy cook it yourself ones.

ok fair enough so what would you rather?
a cynogen mod with archos firmware or linux distro (Whatever) and cynogenmod?
im not saying dont work on a custom rom, im saying work on a "proper" custom rom and use the dual boot option for something other than android.
1st step develop root
2nd step develop custom rom
3rd step install another distro
What im trying to say is, develop a "proper" custom rom and leave the dual boot option for something mind blowing!
as to blazingwolf im not trying to put anyone's work down (apart from the fact there isn't any yet this is pure concept)
I could very easily help you develop a working second rom for this but all im saying is wait a little while and see what happens I cant hint anymore than that!!!!!!!!

i know its different hardware but use a cynogen beta like the I9000 as a base, and work from there, even try the original firmware and look to cook that one.
you will be surprised how almost stock the archos one is

the purpose of SDE is to give users a way to dual boot and be able to load "another" operating system. The Angstrom image we provide is just a demo and nothing else. You are free to put anything else, like Android 4.0, Meego, Maemo or whatever else you want...
Hi,
I've started to download all the listed tools from AOSP and from Chulri's XDA post but wanted to start the discussion on what steps would be needed to create a gingerbread rom for our Gen8 devices.
My initial questions:
1- Would the driver's source from Archos that are currently written for 2.2 be compatible with 2.3? Can they reasonably be updated?
2- Aren't there two approaches we could use? Update the kernel to be compatible with 2.3 or back port 2.3 to be compatible with our existing kernels?
I apologize for probably sounding ignorant but this is all learning for me and any help is greatly appreciated. If nothing else, this thread would be a great place to discus the steps it would take to develop a Gingerbread rom from a high level stand point.
Mr. Clown - I'd appreciate leaving this in the devel forum since it is specific to devel for 2.3 and gen8 and not just an "is it possible" thread.
Thanks!!
-Nate

do you have kernel dev experience for linux/unix?
if yes concentrate on cm a lot of development has been done.
there are phones who have almost identical components ( well the usb attached screen is a problem)
the recovery will be hell of a problem too..
if you never worked with that stuff (at least i hope you are a c crack otherwise look for other stuff to learn c .kernel development is one of the hardest stuff you can pick in softwaredev.) look for another project where somebody could guide you and teach you stuff the first project will be learning the second could be a very specific project like this where you have to work on your own

Hi, thanks for the reply. I've been reading just about all of Chulri's posts in his thread and I know $aur0n would answer specific questions if I asked. Other than that, I took a few C++ classes a few years ago but never took the OS/Hardware level classes. I stopped at advanced/e intermediate algorithms and data structures. Either way, I was hoping to start a discussion with this thread about steps that would be needed to happen to build a gingerbread ROM.

i am sorry but you will not be able to develop a kernel with some classes you took i am a dev so i am quite avit with it i come from a completly different backgroud (windows software) but i have a unbelievable hard time to find a starting point with cm7 for sgs although there other developers around

That's understandable. If development is going to be tough or near impossible, I'd hope to try before I give up. Right now I'm learning about kernel development but would love it if someone could help me focus.
Is the touch display driver the hardest part to upgrade? What changed in 2.3 that makes updating the driver so difficult? Or would it be better to "back port" 2.3 to be compatible with archos's driver?

1) I would say one of the hardest parts
2) I think the archos drivers aren't compatible, so ...
3) ... this would be better because then you've better drivers support (for each hardware)
Again:
I think this project is assomeI'd love to be a helper/tester.
I don't know if you read the news, that Notion Ink will release and already have released a beta of their Android 2.3.4 for their Adam device..
I have tested it, since its basically based on the 2.6.32.9 kernel we all got, and not the latest nvidia 2.6.36.3 which it should be
anyways its not worth porting at this stage, its unstable and its basically using all the apps from the adam device which i find less interesting after trying the hc 3.0 launcher and widget use, i am not going back to 2.2 soon.
but so you .. i tested it and there is nothing interesting about it.
DerArtem's cm7 release is probably much,much better..

experience is the keyword or "learn by doing"
I know that you can do it, but I ask you to tell what you change when you port(usually things, not specific), what files do you add, delete, change and what you must change to ported system work(Guide, HowTo or shortly explain) ?

thats no task to explain in a thread..
its all about knowledge and understanding the os, how android loads, and works in general and the more you change, the more you learn..
so "learn by doing" is not = you know i can do it, but a saying when you need to learn how to work with something and its DIY mostly.
I want to learn. Do you know good sites, books or how and from what did you learn?

It has been a looong time since I knew about those things but if I remember your base ROM should have that same Android version as your port ROM.
And if you want an advice, please consider building a ROM from source. Troubleshooting is hell with ported ROMs. Building ROM is scary because it has commands that you don't know yet, but it's way more easy than porting. Trust me.
Here is a guide on how to build ROM from source :
https://forum.xda-developers.com/chef-central/android/guide-android-rom-development-t2814763
@XdaNeko
It's NOT the version of Android what does matter. If that would be the case then an upgrade via OTA never would be possible.
A Stock ROM always at 100% matches phone's hardware ( CPU, GPU, RAM, storage memory, etc.pp ) - it's built by OEM's / Carrier's R&D department, the guys who know best of.
Whereas a Custom ROM necessarily does NOT because it gets built by 3rd-party companies/programmers associations - who think they can do it better, but don't always have the specific Android device at hand.
