I would start with my thread for all the tools you need.

http://xdaforums.com/showthread.php?t=1404442

Then you can start with taking a shot at a stock based ROM, since they really are the easiest place to start. You will need some form of linux ubuntu is really the most supported distro for android dev work, so that is a good start. This can be a VM to start out with, you can use a free VM tool like virtual box, if you want to just to give it a try, but I will tell you a dual boot works much better, and I will be honest I have a machine that just uses ubuntu and does not run windows at all. I have a wine install for things like netflix and such, but other than that.... no windows. That is just me though.

The key is the android kitchen... and that ONLY runs on linux, that where you build your ROM at. There are guys like rdavisct, who do it on windows, but even he would tell you how much of a PIA it was for him, and he did eventually go to ubuntu with my help.

After that you can start to look at compiling roms like CM, aospa, and the like.
[Motorola Atrix 2] alteredlikeness:
I don't want to be the antagonist here :), but I did everything in Windows until I started my attempts at building from source.

Dsixda's kitchen works fine in Windows with Cygwin. I started off building pseudo-ROMs (or rebuilding the stock ROMs) with the kitchen, and then I eventually just used 7-zip and other tools and did it manually.

I currently use Ubuntu 12.04 64-bit in Virtual Box in Windows on my laptop to compile from source. But I did just install 12.10 fully on my old PC... 32-bit unfortunately.. I need to upgrade that comp, or find a work-around to build in 32-bit.. Anyhow, it runs much nicer than windows xp did.

[Motorola Atrix 2] androiddecoded:
Thats awesome. I have both Red Hat and Ubuntu installed. What about the testing? After compiling do you test it directly on your Atrix 2? I have only one mobile and am afraid to test it directly on it. :crying:
[Motorola Atrix 2] jimbridgman:
Yes, that is the only way. That is why you have the fxz and rsd lite handy and ready, just in case. 20 min. and you are back up and running. If you are concerned go buy a 10-40 buck "burner" at Walmart and put your sim in it, for while you test. I am lucky that I still have my HTC hero lying around for just that purpose... Every time I bricked my a2 (doing bootloader work), that was my go to backup.

I never needed it while doing ROM work, because the worst that will happen is boot loops/soft brick, it is nearly impossible to hard brick the a2 testing a ROM that does not have a kernel in it.
[Motorola Atrix 2] androiddecoded:
Thanks sir. Got that :) :)

Will try to contribute something if I can. Kudos to our dev team. You guys are doing a great job. Happy to be a part of a great community :) :)
[Motorola Atrix 2] androiddecoded:
I took the Paranoid Android ROM from this page for practice. http://xdaforums.com/showthread.php?t=2050705

I extracted it using Android Kitchen, but it says boot.img not found. Do we need to add boot.img from our phone or its not needed since we have a locked bootlader. Or should I take stock Atrix 2 ROM?
[Motorola Atrix 2] jimbridgman:
Ok, so you need to let the kitchen create or import a "fake" one, as the kitchen was originally made for like samsung and htc phones and they require one, so the kitchen needs one, it will remove it when it builds the ROM and creates the zip file.

Also make sure you have the edison file, that was listed and where to put it was also listed in my thread on ROM building for the A2. That will help you create a proper updater-script when it builds the ROM, as well as give the proper mapping for our partitions on the A2.
[Motorola Atrix 2] androiddecoded:
I will do it tomorrow. Really thank you for assisting me.
[Motorola Atrix 2] androiddecoded:
One more doubt. I am building ROM from already built ROM i.e. the zip is already compiled, so how can I fix bugs like camera bugs and other things because they are already compiled i.e. in the form of apk.So should I use APK tool which is used to decompile the apk? Is there any difference while creating a ROM from source and creating it from already compiled zips.?? Silly question but I want to clear all these doubts

I downloaded the leaked 4.1 for Atrix 2. But I can't see the same folder format in that like system, META-INF? Why is that difference
[Motorola Atrix 2] jimbridgman:
The issues for the camera are NOT in the apk itself, they are in the vendor libraries, the issue is that when vendor libraries are introduced for certai n things the ROM does not boot.

The best bet until you get better at C code and compiling ROMS, I would not mess with that. You can however build a working CM10.1 with a working camera by using a camera apk from the market, like 360 camera, and there are a few others, you can just drop that into /system/app and build the ROM and it should work for you.

Once you complie CM there is not much you can fix like that, rdavisct and I were doing just that until Wang released his source for the required A2 files (we did find a lot of issues and fix them, but they were actual missing libs and similar back then., It really is a lost cause to use the zip to "fix" "real compiled in bugs, because anything you do like that will not have the needed pieces compiled around it, some libraries will not work right since others that are from CM were not compiled around the ones from the phone, and think that they are part of the CM code, and are not "includes" in the compile.

You can however do a lot of customizing to the ROM to fit YOUR needs, but do not expect to fix any issues this way. Like I mentioned the camera is an easy one, you then just go to settings tell it your "default" camera app is the 360 camera, not the stock CM one.
[Motorola Atrix 2] androiddecoded:
Oh, ok. So can I try removing Moto Homescreen app and setting Nova Launcher as default?

And why is the difference between files between Moto 4.1 leak and Paranoid Android ROM. The regular mapping of folder is not there like META-inf , /system etc..

EDIT: I think I got it. Leaked Moto 4.1 is fastboot file and PA is flashable zip. I think I am right. Can I get the zip for Moto 4.1 leak?
[Motorola Atrix 2] alteredlikeness:
4.1 leak is not a flashable zip.

The meta-inf folder items are for zips that are flashed in recovery.

And, not to dissuade you from jumping in to modding/dev'ing, but you may want to take things a bit slower... Start small.. And read/research a lot.

Sent from my paranoid phone's mind
[Motorola Atrix 2] jimbridgman:
No, there is not a flashable "zip" for the Moto 4.1 leak, you will have to build that on your own with the Rom kitchen, since it is an FXZ, it will not have those flashable parts. The kitchen is very easy to use, it is menu driven and only takes about 30 min to an hour to do what it seems you want to do.

You can replace the launcher from within a flashable zip, but you might have issues, because the MOTO blur junk that is in their ROMS DEPENDS on it, if you do NOT leave it (moto blur launcher) in /system, then a number of things will not work that depend on the moto launcher (they are embedded in the xml files in the apks, and need to be edited to NOT look for the moto laucher), I think it is more trouble than it is worth, personally.

I would throw Apex in there if that is what you want, and then on first boot select it as your default launcher and be done with it, less issues and mess, other than the old moto launcher taking space in /system. BY the way ANYTHING that you put in /system is not really 100% upgrade-able by the market app, so like lets say you put apex in /system, then the market can not update the version in /system, since it is read only, and it will either fail the update, or try to put the newer updated files /data, so you will have things in two places for your 3rd party launcher. It is MUCH better to put any APKS that would come from the market into /data so they can get updates with out any odd issues, just a heads up...

--EDIT--

As alteredlikeness said about the same time I was posting, start a little smaller, and do a bunch of learning, because from what I see you asking about and posting in here, you have a good bit of learning to do, about how the directory structure and things are and work in android, as well as some ROM building basics.
[Motorola Atrix 2] androiddecoded:
Thats true. I am just excited to work on all of it. So I am missing the key parts in trying to jump into it. I will try reading more about it. May be you can mention some task which I could try doing (and which will force me in doing more research) because I don't have any idea from where I should start. I am still in college so I can dedicate lots of time on it.
[Motorola Atrix 2] alteredlikeness:
Start with modding your current ROM or a stock ROM. Try adding/removing things, decompiling/compiling, baksmali/smali, making flashable zips, etc..

Or find a mod you want and try to make it work.. Tear things apart and rebuild just for fun. A lot of trial and error is involved in learning these things, so it's good to have a reliable recovery when testing..

Maybe see my "get started" guide in the Themes & Apps section for some ideas..

If you manage to notice the difference between pentile and rgb on a dpi of 440 (440 dots per inch!), you should call the guinness book of records, because it means your sight is above human.

96 dpi is the average 1080p computer monitor / TV

150 dpi is normal top quality print

300 dpi is the limit visible by the human eye

440 dpi is overkill... pentile or not pentile... irrelevant

Agreed. It's why I bought a One X over the SGS3. But since, starting with the N2, Samsung's moved away from it what's to be discussed? How bad the SGS3 and Galaxy Nexus were or how bad the SGS4 could have been? When GSMArena does their standardized testing we'll know how good the display is in color reproduction, brightness, and white balance. You can't measure anything on a trade show floor except whether a display looks good or doesn't.

[Galaxy S 4 Q&A, Help & Troubleshooting] GGXtreme:
I have yet to see one review of a Samsung flagship going back to the S2 utilize the screen modes during their testing of the screen. The movie/cinema mode drastically improves color performance and accuracy, even if the color temperature target is cooler than competing LCD's. Everyone acts like AMOLED has some inherent blue/green tint when it's entirely down to tuning and calibration, things that Samsung has given users the option to change.
[Galaxy S 4 Q&A, Help & Troubleshooting] BarryH_GEG:
Here are some detailed measurements from the One's display. Spoiler alert, other than in brightness and contrast it's not as good as the OG One X. In fairness to HTC, that may be a by-product of moving from 720P to 1080P and there's not a lot of 1080P displays to compare to yet. I guess we'll see how well SAMOLED scales up to 1080P soon.

The S2 did not have a PenTile screen and was probably the best screen around at the time.
[Galaxy S 4 Q&A, Help & Troubleshooting] GGXtreme:
Not true. You could say that for LCD screens as well (look at all the comparison pics between yellow and blue tinted panels when the iPhone 4S came out), but in the end it's all down to individual screen tuning and calibration. And when it comes to displays, there's no such thing as "true white color". The color white is dependent entirely on the target color temperature, which for the current media and display standard is 6500K. The HTC One's LCD is actually *further* from this target than the Galaxy S3's PenTile AMOLED display.

[Galaxy S 4 Q&A, Help & Troubleshooting] GGXtreme:
It's not, because software pixels can't just be directly translated to arbitrary shapes. Subpixel rendering figures out which subpixels to use for which pixels, meaning pixels can share subpixels with each other in certain cases. Using a subpixel arrangement other than RGB stripe isn't that uncommon and isn't just a PenTile thing. Look at some CRT and LCD monitors:

You're not making any sense. I'm not talking at all about the subjective quality or saturated colors of an AMOLED screen. PenTile has absolutely nothing to do with the 'blue tint' you're talking about, and a couple of posts above yours shows that the white point on the Galaxy S3's PenTile screen is actually more accurate than the HTC One's LCD: http://xdaforums.com/showpost.php?p=39197030&postcount=25 The reason using ANY OLED Android device for photo editing is bad is not because of any screen tint or screen quality, it's entirely because AMOLED panels have a much wider color gamut than sRGB, which is the display standard for accurate colors. All you have to do is change the screen mode on your Samsung device to Movie/Cinema in the Settings and the screen will emulate a smaller gamut, giving you the accurate colors you're looking for.

If you don't believe me, I will post comparison photos tomorrow of the S3 and Note 2 screens alongside a calibrated wide-gamut display color-managed to show a photo in proper sRGB and I will show you the difference between the screen modes on the Samsung devices.

[Galaxy S 4 Q&A, Help & Troubleshooting] GGXtreme:
You've essentially supported my point right there. There is nothing wrong with an AMOLED display, PenTile or otherwise. Soft mods exist because it's software calibration/tuning that holds them back if you want accurate colors. On Exynos devices running TouchWiz ROM's, there is a setting to change the screen tuning without any mods. Unfortunately, outside of those devices and ROM's, mods are needed because the chipset is different and the drivers aren't open source. If you own a Note 2 or international S3, go into Settings->Display->Screen Mode and choose Movie/Cinema and then look at your photos. You'll notice that you can now see shades of orange and red instead of just bleeding red and you can see a more natural green color with a proper transition to blue. When I view a colorful website, it is very close to viewing it on my calibrated monitor with this setting, while the colors are very wrong by default. I will post a picture tomorrow because I don't have access to the devices right now.

Bravo. You are the single first person who is actually informed about the technicalities here in this whole discussion.

It's a pity that the American S3's don't have the mDNIe engine to actually be able to see the difference the profiles make.

And you also don't need to post that comparison compared to your screen - we've already got the data on the international variants: S3 kernel, Note 2 kernel. You actually have photospectrometer readouts on the screen, and you can download the reports linked there. And just as a note: the "before" values are actually the 100% gamut of the screens. Those values are actually beyond the Dynamic profile, just to see what AMOLED is capable of. There's no wonder Samsung actually has an adobeRGB profile on the S4 now, the colour gamut is just insanely big.

And you're absolutely right on the comparison with CRT. There is no fixed physical pixel on the new subpixel layout. A virtual grid is overlayed over the actual sub-pixels and any logical pixel will be free to use the nearest subpixel, decided by proprietary layout algorithms. There's no point in trying to draw overlays over the physical layout because nothing will be correct and correspond to reality.
