Reverse Engineering Modem Drivers - Captivate General

I'd like to begin an effort to reverse engineer and document the modem drivers for Samsung Galaxy S phones. Any developers with reverse engineering experience are welcome to participate in the documentation process. Those that participate in documentation process may not participate in the open source driver development phase. The goal of this project is to create specifications from the proprietary linux device drivers in order to allow open source linux device drivers to be created. The primary focus of this effort is to remove our dependency on Samsung, improve GPS performance, provide 4G support, and ASOP native build support.
Please PM me if you are interested in participating in this process. We need to establish a development site and wiki for participants.

TaintDroid source code released

Hi everyone,
I apologize if if this is not the appropriate place to post this info, but I thought it would be of interest to some people here. You may have seen stories in the news recently about the privacy-monitoring extension for Android called TaintDroid that was developed by researchers at Penn State, Intel Labs, and Duke University. An excellent summary can be found on Ars Technica.
The reason I'm posting to this forum is that we are proud to have made our source code available last night. If you want to play around with the code, you can find it at the TaintDroid website (search "taintdroid appanalysis"). Along with links to the source code, you will find instructions for getting the code up and running on a Nexus One. We have also set up a Google Group for users who want to discuss anything related to the project.
Our only caveats are that we are merely researchers so 1) you use the code at your own risk, and 2) we do not have the resources to offer proper support. We hope that by releasing the code to the public a self-sustaining community of interested users will form.
We hope that you find our code interesting and useful. Happy hacking!

Thanks for releasing the code. Look forward to using it on an incredible rom soon.
http://appanalysis.org/tdro1d.html
I'm assuming that's the link. Couple of questions.
1.I see it's on 2.1 rom, does it work with 2.2? Especially as it uses the 2.6.32 kernel.
2.Since the Desire is basically a Nexus One with sense, has it been tested on that platform or with sense?
Thanks for releasing the source and instructions!
This is what Android needs, as Google is not taking good care of the privacy of it's users.
It's impossible to install apps now, because most of them want really wide rights, but you have no idea what they do with those rights.
TaintDroid at least gives a possibility to peek into what is being leaked.
Soon some of the app makers will start to encrypt their calls to try and and mask what they are leaking. If/when this happens, it should be a warning sign to users about that particular app.

Opinions about open source

Hi,
I am accustomed to the habits of the Linux community. There, if you have created an app, the first thing you do is to provide a g'zipped archive file containing all source code, a README file, and a manual. Then you announce it in forums, get response and comments about your code. Everybody happy.
In the Android (and possibly other xda) communities the source code seems to be "top secret". There are many free apps but very few open source projects. Why is this? Why has every developer to reinvent the wheel?
As you might guess, I created an open source project. This is an audio app for Android tablets, it's a software instrument, and I was unable to announce it here because I have less then 10 posts. Please google for "One-Hand-Synth".

[BSP/SDK] for NEC Renesas EMMA EV2 based Android devices to build custom ROM

This thread is for the discussion related to the NEC Renesas EMMA Mobile EV2 BSP/SDK.
For public information or documentations about the chip itself, please visit
http://www2.renesas.com/mobile/en/emma_mobile/em_ev.html#pageLink04
Why I am posting here?
This thread was originally started at slatedroid.com by one member who had drawn my attention there.
The reason I was interested was because there was a community of Rena3/Opad users there who are having an active discussion of things related to Android tablets based on NEC Renesas EMMA Mobile EV2 chip. The community there are interested to port Cyanogenmod to Rena3/Opad or develop a custom ROM for the Rena3/Opad tablet.
Part of reason they want a custom ROM was because Rena3's firmware is badly implemented. Users have reported many bugs on it and the chip's performance is not fully optimized to utilize its two cpu either.
Their problem is that the source code of the NEC Renesas EMMA Mobile EV2 chip is not publically available, so they can't really do anything other than simple modifications.
However, I have previously stumbled upon the NEC Renesas EMMA Mobile EV2 BSP/SDK somewhere on the internet. With the help of interested developer, in slatedroid's SDK thread, I have confirmed that the BSP/SDK I have is the NEC Renesas EMMA Mobile EV2 BSP/SDK that they need.
I was planning to make it available on slatedroid.com but something I posted offended the moderators there..... And I was banned immediately without warning or recourse.
The slatedroid member who had originally invited me to slatedroid was also banned when he was trying to help me to get my account re-instated.
Hence, I have no choice but to find an alternative forum to continue the SDK thread from slatedroid.com
This forum seems to be a good choice, that's why I am posting here now.
You can visit the original thread here
http://www.slatedroid.com/topic/21660-sdk-possibly-on-the-way/
I have attempted to post this thread on androidtablets.net but this thread was deleted within 24 hours of posting (My account with androidtablets.net is not banned and still usable though....).
It was lucky that Google have a cache of this thread, so I don't have to retype the whole thing again....
Note: the same thread is posted at
http://tabletrepublic.com/forum/cor...droid-devices-incl-tablets-custom-rom-90.html
http://androidforums.com/custom-rom...-android-devices-incl-tablets-custom-rom.html
I believe there are ROM developers here who may also be interested in this NEC Renesas EMMA Mobile EV2 BSP/SDK.
If not, I hope those member from Slatedroid.com would find their way here because I cannot make any post or even read slatedroid after I was banned.
With the help of fourgate from slatedroid, we have already uploaded the entire SDK/BSP on some file hosting web site.
About the BSP/SDK
So far, what we know is that the NEC Renesas EMMA Mobile EV2 BSP/SDK I have obtained is dated around april 2011. There are a number of known bugs inside the BSP/SDK which have been fixed by some vendors by now (September 2011), e.g. a lot of bugs were fixed in our Gen-E tablet by our supplier and we are now (September 2011) using a firmware is now running a kernel which is dated in August 2011.
In order to port the latest version of Cyanogenmod or AOSP, i.e. Android 2.3 or later to NEC Renesas EMMA Mobile EV2 based tablet, you can expect that some work is required to update the kernel and fixed bugs that have already been fixed before...
In addition, we noticed that the BSP/SDK I have obtained is not complete but do contains the most important parts that you need. Yes, kernal source is there....
To get you started, this is the release notes of the BSP/SDK.

Calling for ROM developers
If you are a ROM developer, capable of porting Cyanogenmod or AOSP to NEC Renesas EMMA Mobile EV2 based tablet, interested to work on this and want access to the source codes, please reply on this thread with the following information
1) State who you are
2) What do you intend to do with the file
2) What Renesas EMMA Mobile EV2 based device you currently own, if any. Or state none if you don't have one.
Once I see your post, I will sent u the download link via PM (please do NOT post the link I provide pubically but you are free to create a mirror copy of it elsewhere and post the link here.)
Why do I request these information?
So everyone knows who is trying to work on this because at present (17th October), because there are too few developers working on this and we would like to be able to contact them to seek update or have them available to help out other developers who are also working on this. I only know one developer, who found me through these threads, is actively working on this
In order to keep the BSP/SDK publically available, after you have downloaded the BSP/SDK, I would like to ask you to help us upload, host the file somewhere else and post a reply here to share the download link. Then, I will update the download link on this post here.
Public repository
To help with collaboration, I think we would need a repository to store/merge the code from different developers.
Most opinions received so far are to host these files at github (Or you have a better suggestion where we can put the modified source code?)
I am not a developer and I can't help on this. So, I would need a volunteer to upload and manage this......(anyone?)
nOISEVAULT said:
You can look here for the code.
I organized it in three repositories based around the tar.gz files in the SDK.
If someone wants to reorganize that's fine by me.

Useful informations related to this
For those ROM developers who do NOT have a NEC Renesas EMMA Mobile EV2 based tablet, if you have proven yourself that you are genuinely making contributions towards Cyanogenmod or ASOP build for NEC Renesas EMMA Mobile EV2 based tablet. We are willing to provide you with our Gen-E tablet at a discounted price. Please PM me on this matter after you made some contribution here.
(reserved for additional information)
You can use github for source code management

Another developer have mentioned that before but the most important part is still trying to have ROM developers interested and then they are put the source code up on github.
Being a non-programmer, I can't do these....
Firstly, I am interested in doing rom development for the rena3 which I own (typing this very message on it). I am new to android rom development but not new to android or development.
But I have two questions.
1. Why are you getting banned from forums? At slatedroid the admin said you were only conditionally willing to share the SDK.
2. Why not upload the SDK to github and let us start working on roms for the device.
Something is fishy about this whole thing to say the least.

nOISEVAULT, this is the answer on both of your questions
He's getting banned because moderators think he's promoting his products.
He cannot use github or smth else 'cause he's not a technical user, he's mostly like "people manager" trying to get his team connected to XDA developers.
So, ericwong, what do we need to get started? Can you upload an archive with current version to a file hosting so we can use it to set up a developer repository?
For example, you can use multiupload.com — it uploads your file to a number of free hosting services, so you can be 99,99% sure that the file will be available for about a month.
Oh, I see you don't know how to use github.
Then why not just upload the SDK to a filesharing service, and let the devs who will be interested take it and upload the code to github etc.
I don't think you will interest bees by just TELLING them you have a field of clover. You need to show them.

ericwong, please consider that even this thread looks suspicious. We have no source code yet, but we have an offer to buy a «Gen-E tablet at a discounted price». Not a big surprise you were banned on some forums already. This is not the way the things get done.

One of the interested developer, fourgate from slatedroid have helped me to upload the bulk of the files to a file hosting. However, I have not heard from him since.
I have updated my post with more information, please read it.
I am be more than happy to provide you with the file if you are willing to help setop the developer repository.

I am ONLY trying to help interested developer purchase a unit if they don't have a unit to work on. There is no obligation to purchase. This is NOT an advertisement to sell my products.
I can certainly ask the only active developer to post here to update his progress so far here to proof to you that this is not a hoax.
I can also provide you with the actual source if you are a ROM developer interested to help on this work. (please read my earlier post again, I have updated it.)
As I said. I am interested in trying to work on developing roms for this device.
If you will give us a link to the SDK we can start doing that. Where is the link?
Well, i agree, this is not the way to get things done, put the code there, without conditions and people will join, put just a load of words conditioning resources, and you'll probably get banned again, i'm not a rom developer, but a programmer, i'll start reading about rom deving when i get my device (2 weaks or so), which has an ev2 (is probably the same, just put together/rebranded by a diferent chinese company).
There is quite some documentation available (with no conditions from renesas), this might be lower level than the required level to dev a rom, but probably, scratching a bit more, there is a chance to find more, as for specific components (such as wifi, 3g modules, gps modules etc...) they have to compile with the suported devices by this SoC i can't post the link cuz this will be my 4th post, but i can tell you that what i found is this:
EMMA Mobile EV Series Pamphlet (probably worthless)
EMMA Mobile EV2 Datasheet
EMMA Mobile EV/EM User's Manual (this might be the most usefull)
On the renesas webpage is also the block diagram for the SoC, still have to do a crapload of reading b4 i can even pretend to know what needs to be done to develop a custom rom.

I will put the link in my earlier post then
I know what link you mean....
Regardless of what documentation you find, without the kernel source, you are not likely to be able to do anything significant or porting Cyanogen Mod over. The source is only the starting point, I believe there are a lot more work involved which may not be documentated by NEC on how to make it work.
Please see my PM and let us know here what you can manage to do out of the code.
At a glance everything in this package is published under GPL 2.0 So there's no harm in working on it.
I am working on a github repository of the source code.
OK. You can look here for the code.
I organized it in three repositories based around the tar.gz files in the SDK.
If someone wants to reorganize that's fine by me.
look here:
https : / / github.com / cAPSLOCK7
I had to write the link that way since this forum doesn't trust me enough to post links yet.

Sounds good but even though it maybe published under GPL 2.0, I don't think anyone manage to get the code from NEC or elsewhere....

[DEV] ICS Market Compatibility Help

I'm currently working on understanding exactly how the market checks for compatibility and circumvent it by creating the illusion of whatever features are required despite their non existence on a specific device. I'm not worried about a device not being able to handle an application once it has been downloaded, i'm just focusing on attempting to be able to download directly from the market on a devices that should not be compatible with that software. I'd appreciate any and all information the community is willing to contribute to the cause.
Thanks,
Isaiahhhhh

Open Source MDM (Mobile Device Management)

Hey Guys,
This is my first post in a long time, however I figured I'd give it a shot since it can possibly be an opportunity for someone here.
I am looking for an Open Source MDM (Mobile Device Management) tool for android. Generally since my employer is interested in possibly creating one for our specific project needs.
I've been searching and haven't really come across anything so we are interested in hiring a "consultant" or developer whom has made apps or custom roms with MDM features, or has already created some form of MDM and can participate in an open source MDM project.
This is a great opportunity to participate in a project that WILL BE DEPLOYED out in the field to hundreds and eventually thousands of tablets.
If you are that person that can help, or know of someone please let me know.
Or if you know of an Open Source MDM solution already out there, that would be greatly appreciated as well.
My e-mail is [email protected]
Thanks,
-E
Open Source MDM (Mobile Device Management) tool for android
We are also looking for an Open Source MDM for Android. Thus far the only potential options I seem to be able to locate are OpenMEAP, and potentially Funambol (though its more carrier oriented these days).
Please let me know how you go as we may be interested in contributing.
