[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.

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.

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.

Program to overclock MTK6516 cpu

I was looking for a program to overclock MTK6516 processors, from china smartphones with Android, but didn't found anyone witch works.
Somebody knows some program or would like do develope it?

I want this too. I've tried many apps like SetCPU and No-Frills and none of them work.
Most chinese Android devices like the Hero H7000 have pretty decent specs at a pretty damn good price. However, they all use the god damn slow as MTK6xxx CPUs.......

Want something like this too!
Would be nice if one of the developers can write us something

You can't overclock from an app before modding the kernel to allow oc
And to mod the kernel you'ld need the kernel source

kernel unfound since we do not know the brand and manufacturer
Is hard to find it since there is no brand for it and i had been finding it since i bought a Hero H400 android china phone.
Mine CPU is mtk6515 too ~
Anyone tested to root the china phone before?
Thanks.

I've rooted my Gooapple 3G and tweaked it a fair bit and removed the bloatware and managed to get some speed increases that way, but still waiting on Kernel source to be able to do anything more.
The X10 Mini runs the same Qualcomm msm7227 processor as the Gooapple 3G and its widely reported that 787mhz is possible and stable with the X10, so would be nice to have that extra horsepower but until someone comes up with the source it aint gonna happen sadly.
I wonder if its possible to take the hw drivers etc from the Gooapple and merge it with the X10 Mini Source and create a hybrid rom for the Gooapple??

hi thebtman,
You are from Malaysia so this Gooapple 3G.
Need you to give commend on:
1) Camera 5MP?
2) CPU?
3) RAM & ROM?
4) Internet setting for this phone tested?

Any chance in finding an overclocking app for this type of kernel? I've rooted mine, a Star A8 aka Plum Velocity (present on gsmarena) but all the apps told me that is not for my kernel

If you don't have the kernel source, but your phone can be rooted. You can make a Overclock module and load it

And how exactly do you do that?

Why is the kernel source required? It's not that hard to decompile the kernel and hexedit some parts, I just fail to recompile it since I don't know the cmdline for those mediatek processors

[Q] ROM for SMDKV210

Hi ppl,
I have a tablet with Android 2.2. I think that it´s a Sinor M8 but I´m not sure (How can I see it?). The problem is that the OS doesn´t work well, for example, Google tells me that it´s an unknow device. My question is how can I reinstall Android 2.2 or higher (I prefer Honeycomb). Is there any ROM for this device or an tutorial of how can I compile the Android source code for this device. The device has an ARMv7 Processor rev2 (v7l) and 512 MB. Is it a good decision to compile it?
Thanks,
Gabriel

I saw that my device has SEC-SMDKV210 8in Android 2.2 CortexTM-A8 512MB 1Ghz HDMI. Is there any ROM for this hardware. I saw that many devices have SMDKV210.

ROMS for your device
Hi gabvalentin,
You can find ROMS for your device at www.slatedroid.com
It the best site for tablets based on android OS.
Let me know if you find a good one

[Q] Help needed on building custom Android for a new Tablet

Hi,
Right now, I am looking into building custom Android OS. Here is my constraints,
-- It is a custom build for a new Android tablet
-- It should launch our own app when the OS boots. This app will be main entry to the tablet. Need to lock down/remove all the other apps and launcher screens
-- Device drivers are need to be changed while building according to the hardware
-- There is no constraint on which version of Android need to be used
Hardware details of the tablet:
1.2Ghz Cortex A9 processor,
a 7” display of 1024x600 resolution
comes with Android 4.2
Do I need to look for building a custom ROM or with a new design of Android launcher app I can enable these? For installing new device driver I hope I need root access. I have searched a lot of tutorials on all the topics. Can anyone suggest me where should I start with according to my needs?
Let me know if I need to provide any more details.
Thanks!

[Research] Supported MTK Custom Roms?

Hi All,
I'm looking for active MTK Custom roms.
I've been browsing all over, but have been unlucky in my search for the moment.
I recently bought an android smartphone on aliexpress and it's a budget phone with moderate specs.
But I'm unsatisfied with the current factory performance of current OS, so I'm searching to replace it with something I might optionally tweak over time as well, but any active custom rom will do.
I'm specifially using the MTK6899 cpu on this phone.
I had to aswell already factory reset to fix storage capacity issue, so not a good sign to begin with either.
I'm really looking for any answer to clarify my quest/research in understanding the possibilities to port this phone to a different rom.

AFAIK Mediatek's source code for their chipsets isn't open source, hence developing Custom ROMs suitable to a specific Mediatek chipset is impossible.

Hmm that's a bummer, if only I knew this before acquiring this phone, right?

So should I aim at finding one for another mediatek chipset?
Or will there be too many issues caused by incompatibility?

As I can see you didn't get it.
A Custom ROM basically doesn't depends on Android device's chipset, it only matters with regards to being a 32-bit or 64-bit chipset.
Developers of a Custom ROMs claim their Android ROM is oftentimes faster, more efficient, and use less memory because
they ripped out useless garbage, such as OEM/ carrier installed apps ( AKA bloatware ) or
they optimized the kernel. For example, an undervolted kernel can provide a much better battery life than the stock one.
That's all.

(noob here) regarding a tablet
What device info do I need, other than 32/64bits, in order to find a ROM that works?
and I mean basic functions, browser, wifi, touch screen etc... (No need any GSM/celular/mobile etc..)
