That quote suggests that writing operating systems for mobile phones it not what you do 8 hours a day, 5 days a week. You have been given answers by a few members with a lot of experience in that area. Those answers range from "impossible" through "incredibly difficult" to "impractical". Either way, it is not a task one person can take on, "as a way of learning things".

Where do you start? Spend a few years studying computer design, a few more years writing software, enhance that with some system programming and then you will have a rough idea.

The only meego part in asha is harmattan homescreen design with "squircles" or whatever they call it ...

I would not be surprised that meltimi platform used asha's hardware internally... but this is dead end right ?

I feel that RE forces should focus on devices that really worth it (RIM lumias ? ithings etc)

Okay... Since getting Meego to work on Asha requires:
1. knowledge of hardware inside it (for example, knowledge of processor to compile the kernel for it; knowledge of screen to get any UI onto it; and so on);
2. drivers existing for said hardware;
3. boot-loader unlocked to accept random operating system without complaint;
4. maybe, something else...

I would say: go from opposite side. Series 40 OS, pre-installed on Asha, already includes drivers and operating system.

If there is something wrong with it (lacks basic functionality, right?), then you could begin with programming applications for it?

Customizing the operating system, replacing (if possible) the default lacking apps with your own open-source (if you wish to share them :-) ) ones? With time, you could have more-or-less open-source operating system on Asha, customized to your content?

I do not wish to lock you to single operating system, and to Java programming - but it seems to be easier route than trying to get a different operating system work "from scratch". This way, it may be possible to just slowly replace Series 40's bits and pieces with better-working ones.

Some links:

http://www.slideshare.net/nokia-deve...0-java-me-apps
http://developer.nokia.com/resources.../3456/?id=3456
http://developer.nokia.com/resources...k&category=s40

P.S. Nokia Asha platform is later successor of Series 40; Asha 311 has Series 40 operating system.

Thank you. Best wishes.

Not sure why this is still even being discussed.

No problem. I have never met a Java-based phone before, so I am just going to give random links, in hope that they help:

https://github.com/nokia-developer/lwuit-for-series-40/ For developing applications
http://stackoverflow.com/tags/series-40/hot For asking questions and finding answers
http://developer.nokia.com/community..._for_Series_40
http://developer.nokia.com/community..._on_the_phones
http://folder.mywibes.com/mobile_coads/hack_nokia_s40/ Multi-tasking?

It seems that accessing system files is not easy - but hopefully, it will not be the first thing you need to do: http://nokias40club.webs.com/apps/fo...s/show/3361345
http://xp-twiks.blogspot.com.au/2010...rity-make.html

For official Nokia software (flashing, accessing all the files, back-ups and the like? Internet seemed to say that it works for Series 40 devices): http://www.cpkb.org/wiki/Nokia_Phoenix_Service_Software

Service manuals and schematics (hopefully, you will never need them): http://www.cpkb.org/wiki/Nokia_Asha_...service_manual

I am not sure if there is an active Series 40-dedicated developer community out there; http://nokias40club.webs.com/apps/forums/ definitely seems to be too slow, like dead.

You are welcome here. No phone should remain a dark and closed place... never mind the intention of manufacturer.

Thank you. Best wishes.

Thank you Wikiwide, and also pichlo, juiceme and coderus to make this s***** question become also informative and benefiting.

I have two Asha prototypes (RM-919 and RM-922 dual sim, both with a different back key than commercialised ones) wanted to say if anyone attempts to replace the OS I'm happy to give out the device for developing. They are really useless...

Sorry for offtop but what about Asha 501 and double tap feature - it use accelerometer for double tap detection. Is there any way to read accelerometer registers from asha so we could use similar settings in n900?
I tried configure accelerometer in n900 but with little success (too sensitive or too little). From asha videos I can see that it works quite good.

The only one who has helped is Wikiwide. I'm thankful to him.

Other you mentioned have been mostly discouraging.

What was that word you used which started with 's' followed with 5 asterisks? Why did you use that word?

I did not found "the others" I mentioned are discouraging - in fact I found them encouraging, at least I have a clearer understand of "how phone works" or "how to build a smartphone" after reading their post.

There are thousands of words begin with "s" and has 6 letters. Could be simple or stinky or whatever you think it is.
