[Solved] [Q] Build Android for phone on Qualcomm MSM7227 (Motorola Quench XT3)

Hello everybody!
I need an advice on where to get drivers (or what kernel options to use) for my phone (Motorola Quench XT3) build on Qualcomm MSM7227 chpset.
It would be cool to be able to compile new version of Android from source, like gentoo or LFS; we wouldn't depend on Motorola's software updates. The only thing that seems missing is drivers and kernel configuration. (May be I am wrong - correct me)
So how do I find out what drivers/kernel options to use for my hardware?
Any help is appreciated. I would make an understandable guide for compiling Android for Motorola Quench XT3 if I succeed.
Upd:: Motorola Quench XT3 is a "Boston Orange" phone. Look for mods on cyanogenmod forum, in the z71 variants section.

Therein lies the problem.
Linux drivers for phone chipsets (mostly Qualcomm) are often provided as binary lumps for a specific kernel version. When kernel sources are made available for a specific phone then we can generally compile a full AOSP build by making sure that the kernel we build is compatible with the binary blobs, this get more difficult as the framework gets upgraded and depends on features of newer kernels.
So the things to look for are:
What version of Andriod does it run, what do you want to run?
Have Moto released kernel sources yet?
What are the GPU/Radio/BT/Wifi/Audio chipsets
Do we have binder-friendly driver source available for any of the above.
This is all _hard_ stuff and generally if you've never compiled a Linux kernel before this is not the place to start.

This is OK as long as binary drivers are available for new kernels, I guess.
What version of Andriod does it run, what do you want to run?

It has Android 1.6, and my goal is 2.2.

yes, they have sources available for download. I downloaded, but couldn't figure out what ".config" they use, in the bundled script "Android.mk" that depends on external variable KERNEL_DEFCONFIG.
What are the GPU/Radio/BT/Wifi/Audio chipsets

Ok, I am trying to find that out. Couldn't find specs in the net (including Motorola website), they only give processor (Qualcomm MSM7227) Is there a command like lspci on Android?

What is the place to start then? Actually I've configured and compiled kernels for several desktops/laptops, they are fine. I am not any kind of expert, but may be it isn't too difficult to build a working 2.2 Android. There's almost no hope to get it from Motorola. Also I don't care about Motorola-specific software.
Overall, thank you for a good & quick response. I will try to figure out exactly what hardware it uses, and post it here.
P.S.: what else people do to upgrade their phones when it isn't supported by manufacturer?

It's MSM7227 !!!
Hello people!
After a lot of reading I start to understand concepts. Turns out, my phone has a good and popular chipset Qualcomm MSM7227. The same chipset is used in, say, HTC Aria and HTC Legend, which are well supported by cyanogen mod. And looks like chipset determines all major drivers I need! (probably except minor things like flash light)
So, I need help of somebody who knows these things better than me in the following questions:
What could be a difference in firmware between (say) HTC Legend and Motorola Quench XT3, which share the same chipset?
Is there a "generic" build for MSM7227?
Any input is greatly appreciated.

Unfortunately that is rarely the whole of it. Slight differences in implementation can make all the difference. E.G. the radio itself has a firmware that may fundamentally change the interface presented to the CPU. Sound/Display/3D are also up in the air.
Short version, if you can find out the chipset driving each of the above (not just the CPU/Radio SOC) and you can either find:
1. 2.2 binary blobs from another phone
2. Open source drivers that can be compiled for the 2.2 kernel
Then you may be ok.
The reason I said that this may not be the place to start is that what you are trying to do here is get binary blob drivers running for a kernel they were not intended to run with, debugging that is some heavy magic on a desktop, even more so on an embedded device.

I also have the same phone and i was looking for a froyo mod.
I would be willing to test it out (i have the same phone ).
I should warn you though i have no mobile phone hacking experience!

SilentMobius, thank you much for good explanations!!
I googled more, and I have strong suspicion that Motorola Quench XT3 is the same as "Orange Boston" phone. That piece of hardware has been manufactured by many companies under many names (GigaByte G1305 Codfish, Apanda A60, WellcoM A88, Vibo A688, Cincinnati Bell Blaze f800, Commtiva Z71, Muchtel A1, Chinavision Excalibur, Motorola Greco, Nexian A890).
Though I am not sure that orange boston hacks would apply to Quench XT3. Is there a way to check their compatability (in hardware, radio firmware, etc) ?

Cyanogenmod
Turns out we are lucky - Quench XT3 is a part of "Boston Orange", and it runs cyanogenmod. This is very nice, and there is no need to make rom from scratch. Moreover, everything I was thinking of is already done for this phone.
Look on cyanogenmod forums in z71 variants section for mods and other information.

Thanks a lot

Uh, could anyone help me?
I rooted the phone with Universal AndRoot but when i click on z41 on rom manager it gets an error.
Help?

In ROM Manager the phone is known as an Commitiva A71. You are selecting the wrong phone.

[Q] Fedora-17-beta-armhfp-xfce on Xoom?

Fedora has released Fedora-17-beta-armhfp-xfce, a system image compatible with Tegra devices. A kernel image is not included. So, my first question is: Are there any kernels being tweaked and developed by xda members that are compatible with the the Fedora release? If not, it appears from the many posts in the forums asking about Linux on arm tablets that there is a void to be filled.
I for one want to be free of big brother "Google" and regain not only full control over my device, but my privacy too. Richard WM Jones describes how he installed Fedora on a Trim Slice with Tegra processors. rwmj.wordpress.com/2012/02/29/trim-slice-pt-3/ Can't this be done with the Xoom using a hacked kernel being tweaked/developed by an xda member? Is a kernel already available with drivers that make the Xoom's hardware fully functional in a Fedora installation?
Can the "U boot" ROM supplied with the Slice be ported to the Xoom? We need help from knowlegeable, experienced developers here at xda to make the possibilities a reality.
Thanks,
Armido

May 26, 2013: The short answer is apparently no. Not even Ubuntu Touch will replace the android core. However a growing number of linux distributions can be installed using installers like 'Linux Installer' downloadable for free from GooglePlay. This includes Fedora. What is the point of having Ubuntu Touch on tablets if the rich, robust and numerous existing linux programs will not run on Ubuntu Touch?

MTK6575 Based Devices Cyanogenmod

Hi Guys I Want Someone Who Can Help Me To Build CM For MTK6575 .
I Have LG Optimus L4 II E440 Its MTK6575 Based Device And I Have Source Code .
I Think It Will Work On Other Devices .

Even if you have the source code for that device, you can't just build generically for anything with that processor as even if just one part of the device is changes that part would probably cease to function. Also when it comes to building something like that I'll see what I can do once I have a fully functional computer but the source is like 40 GB so it would be a big investment already just to download it. Which version of cm?

I made some 1.5 based rom at one point for my g1 but I remember like...none of it. Once you read up on building android you should be fine. I'll just warn you you will be working with BIG data, probably around 40gb to download.

[KERNEL] Major Linux Updates

Hello, I decided to come up with a project that aims to port higher Linux versions. When I say higher Linux versions, I mean those that are Linux 3.5 and up. The goal is to port Linux major updates as high as I can, but the main priorities are one that are LTS like Linux 3.10, 3.14 or even 3.18.
Only Android 7 will work on non-LTS versions. Oreo/pie and Android 10 support will be added only on LTS versions to lessen the conflicts when merging non-LTS versions.
What works:
Boots
Battery
Charger
Touchscreen
Display
USB
Sound
Buttons
Deep sleep
Camera
Video playback
Fingerprint
The rest of the sensors
WiFi
Bluetooth (works on Linux 3.7 and up)
Internet connection
Anything else I can't mention
What doesn't work:
You tell me
Drivers that can't be updated (yet) due to them being heavily modified by CAF and Samsung:
USB
Sound
MMC
Newer versions are more stable than the other due to the fact that I fix more bugs with every update.
The highest version as of now is Linux 3.8. I can only merge major updates during weekends due to my work.
Sources:
Linux 3.5
Linux 3.6
Linux 3.7
Linux 3.8
Linux 3.9
Feel free to open up issues and submit pull requests
It is highly recommended to delete mpdecision from /system/bin/ before flashing

These are kernel updates. Our device comes with Linux 3.4, but I've managed to update that up to 3.8

What a Huge Task! As Well as a Pain on the Ares!
Now, I do Have a few Q's for you.
1 IS this "Kernel Patch" Just for your beloved Galaxy S5's ?
2 Will this be for the "Basic" Kernel in an OS (e.g. LineageOS) ?
3 Wouldn't this hurt some of the "Custom Kernels" that we currently have and use?
And of course I must ask, how far do you intend to take this (e.g up and coming 5.7 ) ?
That Said, I am in! I have downloaded all the Kernels . Mostly to compare your changes. Have also saved your GitHub page.
Am wondering though, With some of these "Custom" Kernels..... Wouldn't we see much faster , smoother , and hopefully more Darn Battery with some of the Tweaks that we have with them? Or at least with some kernel manager?
Or, would these break those Kernels (now thinking about it)?
Certainly will be watching this!
Again , this is a huge task to undertake! Sure would love to see 4.1 and above for our phones. Maybe with Your updated Kernel, we could really see some major changes with our phones.... Plus, hopefully easier to Port into the likes of Android 10! ... or Of course jumping a bit here, and a bit positive, but Android 11 !
Good luck sir

1. This is a full Linux upgrade. Nobody has ever done that to our beloved S5 cause it's a truckload of work
2. Uhm, I don't know. LineageOS is very strict on what kernel base to use, but I may propose to use this as a base when I reach 3.10
3. This project might be a good base for custom kernels since it is more updated and I will use this base too for my future custom kernels
4. As far as I can and as long as it works. Of course, I don't wanna die yet by not going too far.
Certainly, it won't break any kernel managers. You can even clone the latest source and add some custom features. It's up to you, but right now, in the process of upgrading, I won't be adding any custom features
Regards

Hi guys! Linux 3.9 is up!

thank you very much for it.. I bet it's ugly as hell, but you learn a lot..
I'm patiently waiting for 3.10.0 since that's required by docker (running debian using Linux Deploy)

Nope, S5 only. And at this point klte only until @pascua28 is finished bringing the kernel up to 3.10

Only working properly is klte, for now. Other variants might work but with bugs. Will fix for other variants when we get to 3.10

3.5 to 3.9 didn't work for me,I have klte

didn't work?
I ran 3.8 for weeks without any issues.. what exactly does not work?

Is it possible to use a recent Kernel in tab2?

I was wondering if is it possible to use a recent kernel in tab2.
There is a Linux system (Maemo Leste, based on Devuan (Debian without systemd)) that runs in a Motorola Droid 4, that uses a recent version of the Linux Kernel (5.11) and has the same CPU and GPU. https://leste.maemo.org/Motorola_Droid_4
Would it work in tab2?

Well as far as Android is concerned, in the future, we might get Android 11 with the 5.4 android common kernel. That won't be a easy job to make though.
To port to mainline (5.15 kernel or newer) is kinda possible but it requires even harder work, indicated by the fact that there is only a finger-countable few of those get to this stage, and even if you get it, some features won't work.
