Anyone interested in developing a custom kernel for the j727p? I just noticed that the updated source code was released for oreo and im going to try and put something together but I still need to learn more to get everything right.

[Q] ASOP Sidekick 4G ROM?

Am I the only one who is unhappy with the slim pickings of ROMs that are available for the SK4G?
Does anyone know anything about an ASOP ROM?
It's AOSP (Android Open Source Project) and you're not the only one not happy with the current SK4G options. I personally want MIUI or CM7, but seeing as we're currently stuck with Froyo, we'll have to see what the devs can cook up.

For future reference, questions go in the General forum, not the Development Forum.
As for AOSP or MIUI, I know that AyoTeddy and Revolution are currently working on separate MIUI roms, and for AOSP, I'm working on that, but not sure exactly what you want from AOSP that's different from what we have?
If you are unhappy with the selection of ROMS here, you are always welcome to make your own, android is open source for a reason.

If they want the real miui we will need some sort of aosp gingerbread to start with and a custom CM7 kernel or something.. Since we dont have either yet I guess we'll have to make the best out of what we have now like we have been. But those wanting a taste of miui may like what I have planned for my next release.

And so anticipation had set in, i can't wait ayoteddy. im very excited. SMX was great, and SMGC was awesome, and now with this? whewwww. think i better go lay down, lol.
I'm also interested in porting CM7 to Sk4g cause I'm used to when I had G1 and now I'm using Sk4g without it.
I have programming skill and understanding of linux architecture. I've read about android architecture and AOSP and how to build Cyanogen from source. I'm running a tech firm (about 30 employees) - we are developing games that's why I don't have enough time to port it faster but I'm going to do it in a month or two.
So, I need help from experienced dev for android who is willing to build AOSP rom for Sk4g.
Here is what I'm going to do:
1) I'm gonna try to build Kd1 rom from source (there is an opensource code from samsung) and flash it to my Sk4g
2) Change the platform in original source to AOSP 2.2 and remove all TMOBILE apps - then build and flash
3) I'll try to find all hardware specs of the phone to compare with other samsung devices. It can help to exctract proprietary drivers of the phone. I think that the drivers are commonly the same, but I need to identify it.
After that I'm gonna upgrade to AOSP 2.3 but I don't have enough knowledge right now. Can some experienced devs answer the questions:
1) Are the linux kernels of AOSP 2.2 and 2.3 identical?
2) Can I use device drivers from 2.2 on 2.3?
If someone is interested in this project - please let me know and let's start the job. I think that my progress wouldn't be fast due to lack of time.
Thank you for joining the Sidekick 4G section , & we welcome you but if you want you could pause the game's for the ROM if anything & Question 1 is a no & Question 2 no cause they have to be compiled with the 2.3 kernel .

Revolution, thanks for relaying my responses.
jmpz, I tried building the source before, but was unable to build it completely, but that was possibly because of some errors with my dependencies. The kernel compiles fine from source, you just need to pull initramfs, or you can get it from Dr. Honk's github.
Thank you for your answers.
So, can anyone enumerate the list of drivers which we should extract from kernel?
I can name these:
1) Keyboard
2) Mic
3) 2 speakers
4) buttons
5) front camera
6) rear camera
7) trackpoint
8) lcd
9) digitizer
10) 3.5 jack
Please correct me and add missing
If I understanding it rightly the key problem is getting proprietary drivers from the kernel. Right?
nope, the key problem is trying to build the system entirely, without any errors, which may be easier with someone following a stock designed build environment. I don't use Ubuntu which is what has the listed dependencies for every tutorial I can find. You can get the drivers out of Dr. Honk's voodoo kernel ramdisk here: http://forum.xda-developers.com/showthread.php?t=1145139
There shouldn't be any problems if you just set up a build environment following the directions in any of the tutorials, then add the platform from the samsung source.
I'm a linuxoid - so these tutorial are for me. Thank you for the link.
By the way, drivers are in Linux Kernel, so I don't think that I need to use Samsung Platform from the source. Instead I wanna use platform from AOSP or Cyanogen. Correct me if I'm wrong.
I think that grabbing drivers from kernel source from samsung would be enough to build the rom.

I 100% support your efforts. I want Cyanogen on the SK4G badly, but I'm not sure what kind of help a non-programmer like me could do, but do have some experience with flashing phones and such, so if there is anything you need let me know.
If you do get rolling heavily on this, I'd be willing to donate monetarily to your efforts.
If anyone can get CyanogenMod 7 on the Sidekick they would definetely get a donation from me. Id be thrilled. Glad to see its going to be worked on.

[Q] Aosp and Kernel

I am building an aosp ROM for the galaxy player 5.0 as an independent study at my school. I have the stock kernel for it that I extracted out of an odin image and I was wondering, do I have to build aosp around the kernel because I heard aosp kernels aren't good with the drivers and I need every function to work. I have found many tutorials for aosp and I am not going to use Googles since I can't understand that as much as other ones on the internet. Can someone enlighten me on the subject so I'm not going to fail, its due by january and I am still on the fence about whether I can do this. I just need some guidance and not to have somebody do it for me.

T-Mobile S3 Source

Hey all, I am trying to start a ROM from scratch for the T-Mobile variant Galaxy S3. Trying to set up my repos and tree so I can compile a custom samsung T-Mo ROM based on the current OTA update (4.3). Any help or point in the right direction to get these repo's out would be great. I've seen a couple more people trying to do the same and I would really like to get away from dsixda's Kitchen (no offense )

have you checked out cm's repo for the tmo s3? that's probably where you'll find the meat of the repo.

I don't think samsung released source for their touchwiz roms. If you really want to build from source and don't mind AOSP then may I suggest looking at omnirom? If you can get that ported over and running that would be amazing.

[Q] Android 5.0 Lollipop Discussion

So 5.0 is out on the SDK. Has anyone decided to try to start making an AOSP build of Lollipop? I'm new at developing and I am currently setting up my environment. I have my own captivate and would like to start building AOSP for it with anyone who would want to start

I have plans to do it as a project. I make no promises however, but I can't see it being terribly difficult.

I too would love to see lollipop on my captivate if you have the time, and would be more than willing to beta test if needed. Thanks
Looking for Lollipop in captivate
Hi,
I also eagerly waiting for Lollipop roms [captivate.] And willing to test roms on my device.
I'm currently in the process of building my development environment so hopefully lollipop won't be too far off

[?]Nethunter Kernel

Hey,
Just wondering if anyone has or is working on a Nethunter Kernel for OP7 Pro.
Everything but the kernel with wifi adapter support is already in Magisk, so just the kernel is needed these days.
Damn, I guess it's not needed here.
Get source for one of the custom kernels that are already available . And then apply the net Hunter kernel patches and compile
https://github.com/offensive-security/kali-nethunter/wiki/Modifying-the-Kernel
Let us know that works out for you...
so one must use the source from a custom kernel and not the official? what is the reason for that?
was considering to try and build one but has never done it before, watching this video it doesn't look that hard
something else I should have thought about before trying to build one?
Did anybody get the nethunter kernel complied I get errors Everytime I do it ,hoping somebody else had better luck and would not mind sharing
