I've been following the development of so-called ROMs for the Vibrant (and other SGS devices), but I have yet to see a single AOSP ROM. Even when Samsung released the original kernel sources for 2.1, there were no AOSP 2.1 ROMs. Why not? Is it because they don't know which BLOBs to pull for insertion or the proper vendor overlays?
Some developers have done great work with SGS kernels (especially supercurio and his Voodoo kernels ... eugene373's tend to always wipe the internal SD card unnecessarily ...). But, a kernel does not a ROM make ... therefore I ask, what is truly missing to build an AOSP ROM. I've gone through the sources, but I don't follow makefiles too well.
I know we have another month or so before Samsung is obligated to release their 2.2 kernel sources, but that should have no impact on 2.1 AOSP ROMs. Therefore, I ask "what is the hold up?" What is missing, and what might I contribute ...
Need 2.2 source code...
2.1 is a dead horse--why bother when 2.2/2.3 are out?
The reason to bother is to at least get AOSP running. Once its on 2.1, it'll be easier to get 2.2 AOSP running on it. But claiming 2.1 is a "dead horse" is the wrong path ... the real question still stands: after 9 months on the market their still are no AOSP ROMs.
MIUI
Now that vibrant 2.2 source is released ... we finally have a REAL AOSP port and my all time favorite from my old HD2 the MIUI.... so keep your heads up and wait for it to get finished.
Get a custom rom. There are so many good devs doing them don't waste your time on AOSP....... until they release the actual source code...... on April 22

Except, the 2.2 source for the Vibrant has not been released. The SGH-T959D that shows Froyo sources on Samsung's site is for the Canadian Fascinate, not the US T-Mobile Vibrant. Samsung has yet to release the 2.2 sources.

Except the so-called "custom ROMs" are just modifications on the stock theme, a replacement kernel and a change of some of the supplied applications.
There is nothing close to a full "custom ROM" such as CyanogenMod or MIUI because we don't have Samsung's sources. What is passing for a "custom ROM" for the Vibrant are just repackaged files. It is akin to the "ROM cooking" that took place for the WinMo phones, not a truly ground-up build from source that is possible with Android.
EDT/Devs4Android has the MIUI build. From Source.
TW has a 2.2.1 in testing.
EDT has a 2.2.1 Beta released.
TW has a 2.3 AOSP in testing. From Source.
EDT has 2.2 AOSP in testing. From Source.
What you want is out there for you.
Watch the forums and reply when a call for Alpha testers is posted.
Hopefully it won't be long before you see a full TW/EDT/Devs4Android collaboration!
I think what the original poster is trying to ask (and I have the same question) is why were there never any real 2.1 AOSP, cyanogen5 for the vibrant. The source for 2.1 has been around for many months. Were some other proprietary bits missing, was the released source code such a mess that it was unbuildable, something else? With those questions in mind, why will things be any different when the 2.2 source comes out?

Yes, this is more towards what I was getting at. We do not have Samsung's kernel sources for 2.2. And, we do not have a Samsung provided vendor overlay.
When we receive these two pieces, then a true AOSP build will be possible. However, we do have the 2.1 kernel sources, so why wasn't a true AOSP build possible then? What was missing, and can we actually expect Samsung to release the overlay that's needed?
Actually, that's true. I know it was old but why didn't anyone build a 2.1 cyanogen or aosp rom? (Not to say its easy.)

For probably the same reason that many phones with non AOSP firmware running 1.5/1.6 did not bother with AOSP 1.5/1.6 when they were released around the time 2.1 source hit. Why bother developing at all for what is essentially an "out of date" OS.
The only people it seems who actively continue to develop for existing (as opposed to new) firmware are manufacturers and carriers. This stupidity should be left to the manufacturers who still do this.
One of the larger snags way back then (sits in his rocking chair on the porch) was a lack of understanding of the phones proprietary aspects and how to work around them. But we have a fairly clear understanding of Samsung's boot process now, and RFS can now easily be turned into a distant memory.
I would wager a guess that the apathy towards 2.1 will not repeat itself once we have 2.2 source widely available and the low level similarities between 2.2 and 2.3 should have Gingerbread being more than the experiment it currently is. It's been barely more than a week since Eugene's little present manifested and there are already proper and stable kernels available.
Keep in mind that the devs we do have, have done a phenomenal job of cleaning up, speeding up, and drastically enhancing our existing 2.2 release. And perhaps to the point where many will not really care, though I know many would still like to see CyanogenMod6/7 properly on this phone.

Um, that's not quite true. The CyanogenMod.com website lists 0 files available for download for either experimental or stable files. The CM6.1 you must be running is not a true CM build.
Also, CM is not AOSP, but rather AOSP with modifications.

The vendor overlay tells the AOSP build system which proprietary files are needed from the device that are not available in source form. This includes things like GPS and video drivers, baseband firmware for wireless radios, &c.
hi everybody !
a month age i decided to compile a new rom for my Galaxy S absolutely from AOSP source ( branch 2.2.1_r1 ) after some compile-time problem and many painful steps to resolve ,eventually the rom successfully built and can boot it up flawlessly on emulator.
i create a nandroid backup of current rom and installed the compiled one. but i am facing new problem :
1- the phone successfully boots but after short while screen began
flicking several time and the phone go in deep sleep and never wakeup
( power button or menu button does not do any thing )
2- touch screen works only for some second that I can unlock the
phone
3- there is no network available
4- I have downloaded samsung opesource package for GT-I9000. it
contains a folder named 'platform' but when i merge these files to
AOSP , the compile process stops and fails again. if there any one can
help me which files from samsung source should i merge and how ? if
you now the answer and dont have spare time then some internet link or
online document is really useful .i have no problem studding and
reading and searching . reaching to target is my only hope .
I am really disappointed why there is not a good and complete step2step tutorial to compile an AOSP rom for galaxy s (GT-I9000) !!
such docs is available for phones like dell streak , desire , dream , magic , .... . i really want to to active these aspect on XDA forum and with help of all you ( mods and masters ) try to create such tutorial that any one in world can use to refer . i think XDA is the only reference on net to collect and create such help and document. please help me and leave PM or comment to agree ot disagree and from where can i start ?!! thank in advanced .
edit :
there is a google groups post that i send my question in Android-platform . if you prefer please join this group and active that post to ask any question related to 'galaxy s compile from source ' .

Recently more and more Android developer start to developping and propose to upgrade their OS from old Froyo (Android 2.2/2.3 ) to Android 4.0 (ICS)system,even though low level 600MHz CPU/256Mb RAM Android phone
(ex. Huawei U8150 ) :
Refer to beneath thread of their activities:
1. Port ICS transition animations on EVERY ROM & EVERY PHONE Thread
( http://forum.xda-developers.com/showthread.php?t=1342117 )
2. [Huawei U8150] Ice Cream Sandwich AOSP Alpha 3 WIFI+SD WORKS
: http://forum.xda-developers.com/showthread.php?t=1366404
I hope someone of our Archos developer also can consider to develop Android 4.0 (ICS)system for Gen 8 ASAP
well the answer is easy:
and if u would have spend some time in this forum - reading - u would have it already...
Atm we got 3 main developers for our archos devices: sauron/bubu/divx
Since sauron will stick to his UD for a while as it seems hes out of the race atm
The other 2 are wokring on CM7 (-> Ginger) atm.
Even they are doing a great job we still dont have a fully bug free and installable CM7 yet...
CM9 (-> ICS) is in a very early development stage (as u already can see in any other android forum here - mostly alpha builds with barely functionality) so it's kinda meanless to switch over to it atm - since we dont have enough developers for it.
Once CM7 is fully working I think bubu/divx will head on to CM9 ofc (if they still own an archos then )
Even I know u just had good intensions - I think those [Request] threads are meanless most time - as they won't "help" anyone sadly.
Imho: if u want to contribute and take the development a step further or want to help them - join the Cyanogen Bull RC development discussions and help out with bug-reports or anything else u can do...

Hello FrEcP:
Thanks for your update informations.
Sorry!I do not know how to develope Linux or Android OS and just a Android system user
However I always keep watch the new OS improvement and contribute my testing result to developer all the time and wish Archos Gen8 could be better
performace than before!!
ICS Port to our gn8 started!
letama, made an alpha version of an ICS Port for our devices
Look: http://forum.xda-developers.com/showthread.php?t=1404492
Currently the only thing that seems to run is the touchscreen (Actually the launcher is pretty smooth)! And it's booting of course
nice to see progresses in ics development for ics!!
Just rambling here. In order to get ICS ported to the Venue, we need compatible kernel drivers. It appears, from what I can find on the 'net, that Qualcomm isn't releasing drivers for the QSD8250 for ICS. Looking around XDA, I see the HTC Desire (GSM), also based on the '8250, has a working ICS beta found here: http://forum.xda-developers.com/showthread.php?t=1403113. This appears to use a Tiamat kernel, http://tiamat-dev.com/tiamat_bravo/. Using the AOSP 4.0.x repository, the Dell info from http://opensource.dell.com/releases/venue/v4.06/ and the Tiamat kernel, is it possible to pull together an ICS port? I wish I had more experience with this type of stuff...
Dell used the CAF 8260 GB sources when building 4xx roms, they simply backported whatever they need to from their already working 3xx codebase for whatever was needed (i assume)
CAF itself dropped support for 8x50 in their GB codebases, but the 8x60 is close enough it didnt really matter ultimately.
Much of the drivers arnt even in the kernel, they're in the android userland which is Apache and not gpl, hence the driver issue.
Which ever method you (presumedly do) to get the kernel booting under ICS doesnt really matter, but the more difficult/time-consuming methods will ultimately be more useful for porting to newer kern versions.
Don't forget the Nexus One and, IIRC, the HD2 also use the 8250
I would think this would help too: http://www.xda-developers.com/android/qualcomm-releases-adreno-2xx-gpu-binaries-for-ics/
Too bad the development work is well outside my capabilities. Maybe our Korean friends are working on it though.
Guys.!!! Dell venue n dell streak 5got same rom n environment hardware too just diffrence is venue is Hdpi n dell streak is Mdpi .so why do nt we join hands n make ics work for dell or on other hand u can take advantage of our dell streak 5 formus there r few good roms like longhorn 2.8 with Hdpi support for dell Venue and Dcs 1.1.which supports both hdpi n mdpi just need to edit build.prop n may be kernel....whish u all safe cooking ...n Friends in need friend indeed ..

Folks, I can see that Qualcomm released Adreno 200 drivers for ICS several months ago (Mar) (https://developer.qualcomm.com/mobi...phics-optimization-adreno/tools-and-resources).
Information in the above page also says that, the drivers has been tested on CAF M8960AAAAANLYA1030. As I noticed, whenever we get the source code from Code Aurora, there is also a kernel directory included. Do you think that we can start from that kernel to port ICS to Venue?

Yes we can,
But I aint that good into dev
This mobile has what it requires to run ICS
The kernel itself ultimately doesnt matter, as long as it has the right code changes merged in.
The current S5 ICS kernel's lineage is:
S5/405 (dell) -> Phoenix kernel/GB (n0p) -> Phoenix/cm7.2 (hPa) ?-> Phoenix/cm9 (hPa) -> Phoenix/AOSP (kibuuka)
Only the final step involved merging in any changes to make it work with ics, ultimately it's based mostly on the phoenix GB kernel which itself is based on the S5's 405 kernel
S5 405 = S5 408 = V 406 = V 408, they're all the same kernel (with ifdefs/configs for the S5/V).
I'd imagine getting a V kernel to boot ICS period is 85% of the work as the S5's froyo/GB kernels can directly boot V froyo/gb roms, and the reverse would likely hold.
The kernel 405/6/7/8 from Dell can be built successfully, however there are known issues such as after charging, we won't be able to boot the kernel up. I do not have a Streak, so I wonder whether those issues are fixed well in Phoenix kernel Manii? Can you show me how to get the source for the latest phoenix kernel that you're using with your Streak AOSP? Maybe I will try to build with Venue myself to see how things work!
phoenix kernel/ICS - Github
It's currently in the process of being merged back in.
You could try diffing S5 405 with V 406 and seeing what's changed in the source, they're nearly identical, but I dont expect them to be bit identical

Sounds interesting, that's exactly what I did in my custom overclocked kernel. However, I will be able to save some time by using their kernel directly. In fact, I think that 405/407 kernel is not very different from 406 since my build for 405 also ran on DV too.
I will try with their "master"/experimental14 branch kernel first (to CM 7.2.0). Thanks for your information!

Will be waste of time as only streak-specific file is board-qsd8x50_austin.c, other changes are device-independent.
Changes that essential to run ics with hwa:
kgsl3.8 - kernel-side drivers are in drivers/video/msm - direct drop in instead of one that's shipped with stock 405 kernel
include/linux/msm-kgsl.h - to make kgsl3.8 build
(not really)*streak-specific*changes to arch/arm/mach-msm/board-qsd8x50_austin.c - changes in hardware init routines needful for kgsl3.8 (updated data structures, powerrail). In short - do a diff for board-qsd8x50_austin.c between Phoenix and ics branches to find out what's changed - to be honest - changes are generic for qualcomm devices, so direct copy/paste of changes into your device's board file will do the job
Other patches that were applied to ics branch are optional (cpu governors, io schedulers, netfilter specific changes (these are only needed if you need ics' mobile data usage collecting/limits features)) or affect streak-specific drivers only (and are not ics-specific).
So, in short - update your device's board file and use ics branch - that would be enough.

Do you think I can start with the stock kernel, download the ICS tree including the kernel, then do the diff/merge between device's board file from ICS kernel to Dell kernel? After that, the original Dell kernel is patched with new stuffs for ICS, and can be used with ICS ROM?
i can also provide you with all patches made for streak against aosp source tree for shortening your mileage and instructions for a quickstart (my streak is broken at the moment, so i've suspended my development activities and got spare time for that)
please mention kernel for streak's ics is being built separately at the moment (i've got plans incorporating it in aosp build process, but it will take some time)
when i've messed with streak kernel making it ics-friendly i've realised that most of stuff can be made cross-compatible between two devices.
It's 95% the kernel, the only thing left is to turn off the rotation patch and swap out the BCM4325 for BCM4239 drivers.
On stock 3/4xx i can directly load venue roms on my S5 and only wifi is broken. (with a S5 kernel) Everything else works.

rotation is triggerable through kernel configuration menu. check.
as of wifi - is there any known-to-be-trustable list of hardware components for venue?
The V is just an S5 without the hdmi and whatever provides usb hosting.
The only other notable change is the wifi chip.
All the other sensors are compatable, and so is the modem+ril.
(I was able to get 3g working, but not wifi due to the chip being different)
I dont think anyone has done a (good quality) teardown on the V though.
Most I can offer is to pull details android gives back while it's on.
I'm guessing that's how CM7.2 was ported, since hPa didnt actually own a V,
he just took his S5 build, and flicked a few switches.
(it helped a lot that CM7.2 doesnt need any kernel changes to boot, it's just the stock 408 one with a modded ramdisk)
He only had access to a V for like a day or so.

Hi Kibuuka, that sounds good, could you please share?
One more thing I would like to ask is, the stock kernels 405/407 and 406 have issues regarding power (sometime I can see the issue that after charging, screen goes black and we can only quit that situation by removing the battery). How did you address it? (I notice that your kernel works well on my CM7, without that issue - or is just simply because it has not happened yet?)
n0p did enormous amount of work addressing sleep of death issue (which, i believe is one you refer to), so dsc kernels (opposed to stock ones) are free of this bug. Ask him for details (i wasn't involved to dsc development at the point he managed to fix it) as he's best source of information on SoD issue fix you could find
As of aosp patchset - will upload it during weekends.
For whatever it's worth, as soon as we get a working ICS level kernel, I plan on porting TWRP and CWM-touch.
Those require ICS kernels (or rather it's a great deal more difficult to make them run on GB kernels) and I cant port them until then.
I've already gotten TWRP and CWM-touch working on the S7, and plan on porting TWRP to the S10 now.
Edit: come to think of it, I actually have TWRP running on a 5xx kernel (which is HC), i'll try simply porting and seeing what happens

1- You'll probably be my hero if you bring CM7 to the U
2- That brick looks like the partitions were set incorrectly in the configuration and something ended up over a bootloader partition... a full JTAG backup would probably have fixed it
3- Probably, but it's not worth it IMHO -- Android had less features and stricter expectations about hardware back then, while performance wise stock 2.3.7 with AOSP keyboard and some services disabled already easily gets over 120MB RAM free...

Is important to know first device specific performance (procesor, camera mpx, device manufacturer, and stock rom android version, and allocated system ram).
-800mhz proc. Is ok for gingerbread and ics. On an never android os , without overclock you will get lag.
-Camera mega pixels are important, because if value is under 5 mpx and for eg. your device manufacturer is Samsung, you should to stay on stock based roms because camcorder performance is optimized in stock app. Other rom will have lag on recording.
-Android version of stock rom is important because if stock rom is for eg. based ICS (4.0+), you can not run ever gingerbread or froyo roms like cm7 and cm6 , because stock libs was designed for ics+.
-Also system ram is important because when the value is bigger you will get better performance.
Eg. With 300 mb of ram you can run ok and gb/ ics / jb ROM.
GOOD LUCK
