[Q] CM7 and the Captivate - Captivate Q&A, Help & Troubleshooting

There has been an amazing amount of progress on Gingerbread from the CMSGSTeam. Has anyone with a Captivate been using a rom on the Captivate that is based on that work?
Thanks

I am also wondering

We had a really good team working furiously on this project for our Captivates found here: http://forum.xda-developers.com/showthread.php?t=875680
But they ran into some problems (like the camera apk and a few other things) and then Christmas kind of put a halt on the project. Not sure if things are progressing behind the scenes or not, but I hope they are.
Hope this helps.

This was just the Gingerbread port, not CM7. The guys working on CM7 are actually making really good progress with the I9000 but there is still work to do. As for CM7 no one should be able to put it on their phones because no releases are out. CMSGS team is keeping it closed until it is fully functional.

They are releasing nightly builds now that is why I was asking.
Thanks

If you know how to compile the nightly's you could run it on your phone (at your own risk)
You can go here to see what nightly's are avail (note: NO Captivate goodness ) http://forum.cyanogenmod.com/forum-85/announcement-5-cm7-nightlies/
This is still very much an alpha project - they are making headway slowly - but they are having to do somethings from the ground up as they cannot or do not have the necessary code source to work with to get the phone 100% functional today. (Liscensing/lack of Samsung releasing crap is not fun )

Are these links correct for the team you're referring to?
CyanogenMOD Galaxy S Github
CyanogenMOD Galaxy S Twitter
Is their goal to build a AOSP Gingerbread that works on SGS? Are they specifically building it for I9000 or Vibrant? Looking around on the CM SGS forum it seemed everything was geared for I9000 or Vibrant.
Am I correct in my understanding that the main hurdle is hardware drivers since Samsung hasn't released any source for those? (If so why are they against using leaked drivers?)
A stable CM7 rom on my Cappy would be a dream come true, just trying to fully understand the lay of the land.

[Unofficial][ROM]CM7.1 Port to DS7....work in progress

This thread is in regard to the unofficial development of the Cyangonmod 7.1 for the Dell Streak 7. Absoluetelly nothing works. So a lot of work needs to be done.
First git the entire Cyangonmod 7.1 tree from them, and then drop these files into the device/dell/streak7 folder
http://www.mediafire.com/?q1w57v797u9p953
This rips the files from a stock Android 2.2 image, so you need to make sure that you are at a stock 2.2 image. My next goal is to upgrade to a stock HC and try making the scripts for that and see if it gets me closer.
As of right now, it boots "Dell" logo, then goes to the black screen with "ANDROID" on it, and that is as far as I can get it.
Look at the files, and let me know what changes I should make and in what script.
Driver wise, I believe you might be better off trying to backport the stock HC drivers.
GB <-> HC/ICS are more similar then eclair/froyo <-> GB in respect to drivers.
That's the reason it took half a year to hack together GB for the s5 and why it only tooks weeks to hack froyo from eclair
Rumor has it that dell attempted to port GB to the s7 before giving up, they lost a couple months at Q12011 doing that and likely scrapped everything, then they restarted on porting 3.1 then moved to 3.2 and that's why the summer was pretty quiet and why the S5 prob got no updates all summer
I dont have any substantial evidence to back any of it up, but the timelines all line up far too nicely, dell prob has only a single team for the s5/7/venue, the s10 is done by a different company.
Yeah, I am thinking I am going to try that direction next. Got a list of all the libs, now just need to re-write the scripts.

Cm never did honeycomb because google never released source
I've pulled a list of all the files I need to work with, now will be the time consuming part of checking the scripts to see if they are already listed and then adding the ones that are not listed.
Not to sound negative, but with Dell having released the official HC build and so, would people really use Gingerbread on their tablet?

I'm doing this for the same reason any hacker does anything.
For the sheer f*** of doing it.
Currently I am working on building a tegra2 2.6.35 gingerbread kernel.
Hypothetically, if he can get GB to actually work (and by work i mean functional with all the hardware functioning properly) he'll be a dozen steps closer to being able to port over to ICS.
I cant say that it would ultimately lead to ICS, but the documentation generated would help a lot (assuming it's all documented lol)
Documentation......I knew I was forgetting something.
Well, the easy steps right now will be as soon as I get it to boot using CM7.1, i will figure out how to git it up to Cyangonmod and have them review it. Currently I got the information I need to port to CM7.1, its just a matter of plugging that information in. The problem I am wondering is that the current kernel in their directory, I have no idea who built it or what it contains.
Building a working kernel is very tough since I have never done it before. Nvidia does have a Tegra 2 Gingerbread image built and a Tegra 2 Gingerbread kernel build available, its just a matter of me figuring out how to get them to work because I have never done this before.
So this usually consists of me doing the following
1. Run 'make -j4'
2. Get error
3. Research error
4. Attempt some fixes
5. Repeat step 1-4
The s7 is really similar the nvidia's vendeta reference board, and I think that's what dell tried to base their GB attempt off of.
(Also what cpu are you using? -j4 is small unless you're compiling on a laptop or something)

Actually it is the ventana (tegra 2 250) board as far as I can tell.
I've got a couple files that say 'init.ventana.rc' on them, plus 'init.streak7.rc'. These were pulled from the ~/ directory
I am in contact with Nvidia in regard to some questions I have but haven't heard from them in a week, they are probably slammed with questions all the time.
Just wanted to say, that nice to see someone interested and capable in doing something for streak7. keep up mate

Oh dont get me wrong, Its cool that you do that, its the same reason I mess around. I guess its just with Steve working on Honeystreak R8+ and ICS. Just was a wonder how many would use GB.
Too bad one can dual boot. Like have HC on Nand, and boot into a diff Android build on SD. Why would this be cool? Cause honestly.. sometimes HC can suck, least when it comes to mass storage mode. I could see myself using a dual boot at times to boot in GB with my streak 7. =)
the dell streak 7 has a Nvidia Harmony broad also could you not use cm7 Advent Vega as a base
Yes, I have looked into it, and in fact I've stolen lots of information from that build and put into into the build system I am working on.
So before I go on a holiday break, a bit of an update.
Bad News:
I started all over and started working my scripts. Currently its having a problem with my 'recovery.fstab'. Its saying its not there, but I FREAKIN KNOW ITS THERE!!!!!! and its written correctly in my scripts.
Good News:
Two successfull zImages built, one based off of Nvidia's 2.3 stuff combined with DJ_Steve's configuration, probably won't boot because its missing some drivers.
And the other is a DJ_Steve's HC kernel, but I asked him to check over some errors I got, even though it successfully built.
The reason why I built new zImages is because I couldnt' verify who created the kernel file in the github. The label on the folder was 'koush' but I asked him and he said he did not build it, so I have no idea who started the project, hence why I decided to build a new one.
So AFTER I figure out the recovery.fstab error, I will try out both of my new kernels and see which one does the job.
After I take a break.
I got several errors out of the way but....
The CM7 build is on hold, indefinitely. I am currently helping out with the ICS build and it takes a lot of my time and also taking care of my pregnant wife and two children. With the release of ICS, I might not even bother with it after this. And if I do, it will be a casual effort.
I see working on the ICS build as the assistant to a very talented ROM developer a a huge learning process and it is actually helping me become much better at making ROM's.

[DEV][WIP] CM9/Ice Cream Sandwich

I have been working on porting CM9 to the VS910. So far I have gotten it to boot to the lock screen.
What Works
Boot animation
Lock screen
SurfaceFlinger
logcat/adb shell
3d accel is half working. I have gotten SurfaceFlinger to load up and interface the proprietary drivers (from GB) correctly, but HardwareRenderer (java framework) fails because the drivers don't give up a valid config.
What Doesn't Work
Touch screen
HardwareRenderer (fails because HardwareRenderer.chooseEglConfig() returns null value)
Everything else
Currently this ROM is totally unusuable for anything except for development. At this point, I do believe it is possible to get CM9 running, but it will take a good bit of developer effort. It would be helpful for any other developers around here to give some insight on the errors that come up in the adb logs.
How To Build
Follow Google's instructions for setting up a Linux system or VM for Android AOSP building
Follow CM9 build instructions up to brunch command
git clone git://github.com/andyichr/makerom.git to a location, such as ~/android/makerom
Overlay the files in ~/android/makerom/cm9-system/overlay onto the cm9/system directory (this adds vs910 brunch)
Adjust values in makerom.sh to match your own paths (MAKE SURE TO POINT IT AT A VALID KERNEL --I didn't include instructions for building a kernel)
Adjust values in makecm9.sh to match your own paths
Run ~/android/makerom/makecm9.sh to build cm9 (this takes a long time, depending on your system)
If build is successful, run ~/makerom/makerom.sh which will output a ROM which may be flashed to the device for testing
This is very rough work, but it proves that the basic parts of CM9/ICS do function on the Revolution. The cyanogenmod developers have already added some patches to the android source which allow ICS to run using video drivers from Gingerbread. This means it should be possible to get things working.
The current major problem with this ROM is that the HardwareRenderer does not initialize. Immediately after this, the main trebuchet process is killed and the system reboots itself after a while.
I will be happy to do what I can to support the process of porting CM9 to our phones. I read that a couple of other devs may be looking into porting CM7, but I think focusing on 9 might be more worth the effort, since we already have Gingerbread.
I have also attached a logcat to this post which should give developers some idea about what exactly is broken, which will lead to the first steps of debugging and porting.
Any interested developers should fork my repo on github (git://github.com/andyichr/makerom.git) which has the build scripts and patches.
That's about it for now. I very well may have left out some steps along the way. If you try to follow this process and it doesn't work out, let me know and I'll help you out.
ROM Download (very broken --only use for testing and development)
http://www.multiupload.com/GI0MLQYTE0 - Flash this if you want to see ICS boot to the lock screen or help test/debug. It's not useful for much else at this point.
We're getting there! I've already patched the android egl framework code slightly and built a kernel. CM team already patched frameworks/base for 2.3 video drivers. We'll patch what we have to to get this thing running! I am pretty busy but I will follow this thread and I hope for this to be a collaborative, transparent porting process! Good luck!
Nice, get with Mtmichaelson and Cubed, they are working on Cm9 also!

Great! I saw in the CM7 thread that thecubed put up a git repo. I'm not sure exactly what his development plan is, but I'd be happy to fork his repo and trade patches, logs, etc. The more devs we have on this, the better... it's not a trivial task and I'm sure my wife hates me by now for spending so many hrs on it so far.
If I read correctly, thecubed just got a master repository set up for the revolution, so maybe the files that are needed could be lurking in there? I'll see if I can find the link and post it here.

Awesome job so far! For a lot of things to work correctly, it's my understanding that you'll need a new kernel. For at least the touchscreen issues, you need the "idc" file in the "/system/usr/idc" directory (not sure if you have that or not, I didn't get a chance to check yet)
Either way, if you'd like to get in contact with me, hop on IRC and I'd be happy to answer any questions you may have.
Excellent work!

Yeah I see thecube's repo at https://github.com/thecubed/android_device_lge_revolution. His CM files are a lot cleaner than mine... I just copied the crespo config and haven't had time to clean it up yet. I'll do some diffs of his vs mine and see about getting things merged. My github repo has some additional files so what I could do is replace my vs910 device folder with a fork of thecube's repo.
I'm not sure whether his files are for CM7 or CM9 (or if it doesn't matter). I'm new to CM porting, but I'm not new to linux or android app development.

Thanks for the tip. I'll check that out. So far I've mainly been banging my head on getting the adreno205 drivers working, but it sure would be nice to have touch working. That'd be the next priority.
I'm tempted to switch of 3d acceleration but I am focusing on one thing at a time.
I'll hop on IRC. Which channel are you on specifically?
As always guys, I'm happy to assist in testing. Nor very knowledgeable on coding or porting, but I can definitely put my phone at risk

Head over to #lgrevolution and I'll be there as IOMonster.
Yep, for ICS we need a lot of work in the KGSL department in kernel for getting proper Adreno support working... Tiamat is working on adding the new KGSL/USB/Genlock support to his MSM7X30 repo here ( http://git.tiamat-dev.com/7x30/htc-kernel-msm7x30/ ) and after that we need to merge our kernel sources with his (boardfiles, includes, configs, etc)
Booting to lockscreen is great, but there's a LOT of work to be done before we can have a "working" ICS by any stretch of the imagination... ICS is a whole new beast, unfortunately...
Cubed beat me to it.

Thanks so much for all that info.
I'm sure it is a long road to a fully working ICS. I see it as a challenge and will just keep fixing the next broken thing...
I'd be happy to test this. I got a spare revo cuz I had a warranty and this dent on the outer corner was driving me nuts.

It's really awesome to see everyone working on this. I really wish I knew more about this stuff to be able to help. All this is really making me wanna read up on this stuff and learn how to do some of it. Until that happens, I'll be more than happy to help out with any testing or in any other way within my capabilities. I got a Revo just sitting there deactived waiting for that ICS goodness.
Thanks a lot for everyone working on this. Those of us that aren't as gifted really aprreciate the work you guys are putting in.

If you've noticed my post in the CM7 Thread, which somehow 'feels' like it's sparked something off here (maybe just timing, lol), I am beginning to work on this stuff.
Anyone can do it, but the problem is motivation and the willingness to learn something new. You will never learn this stuff unless you're willing to fail and fail again. You learn by mistakes and mistakes sometimes turn into innovation for new things and ideas.
There is a lot of Dev's all of a sudden and I do agree, it's great to see. I was almost about to start looking at the Nexus. When I realized I would lose out on the $130 of extra accessories for my Revo (Car Dock, home dock, extra battery, car charge, etc.), And the fact the the Nexus had no External SD Card, I was like... Nah.. Time to step up and see what I can do to make the Revo a well-supported, up to date, kick-ass device. If LG and Verizon wanna sit on their asses, let'em. We make the phone better anyhow, right? MT, Cubed, and anyone else who has already contributed so much, has made this phone 10X's what it ever was out of the box. And, unlike LG and Verizon, Dev's like MT (and others) don't give us the run around on the next release, but a timeline.

Exactly how i feel. Forget LG and Verizon. You guys are the ones taking these average phones into something great. I definitely gave up on getting any real support from either of them.
I really want to start getting into this. I have a little bit of time on my hands and will definitely be reading up on all this. I think you sparked something with your post lol. I know other people like MT and theCubed were already working on some things but I think you definitely added a little spark lol. Very happy to see other people jumping on board to help out. Hopefully I can too

Yup! The motivation for me has been that support by LG and VZ is diminishing. This is the beauty of open source, though. Now the community can support it.
I believe the Revolution really is a good phone. It's got a good GPU and CPU. It's not dual-core, no, but with a good ROM on there, it can be much more efficient than a dual-core phone that is loaded with crapware.
Cybie did inspire me to put my work up sooner so that we can all focus on it and not duplicate our efforts as much.

OK so I was doing more debugging last night in the EGL/SurfaceFlinger/HardwareRenderer code. I also looked at some of Tiamat's work on the MSM7X30 kernel.
I can see now what you mean with regard to merging parts of that kernel into our own. I am assuming that kernel is being crafted to work with ICS-friendly EGL blobs for the adreno205. Is that correct? If so, then that kernel would have code that would be required to talk to the binary blob EGL drivers for Adreno205 that we would pull from some device that has the same chip and has official proprietary drivers for ICS available. I believe the HTC Droid Incredible 2 is one such device. Is this roughly what you were thinking?
I initially had thought of going down a different path: Instead of using newer ICS proprietary drivers and updating our kernel to support it, I was planning on keeping the kernel we have and the binary drivers we have, which are already made to work with each other. The work then required to get ICS working would be to change parts of the ICS userspace code such that they'd work with our older drivers. I don't have the links on hand, but I believe this is possible because I read about others taking this strategy on other devices that do not have ICS support officially but do have proper GB support. It also makes sense to me logically that the userspace code could be changed to our heart's content to work with older drivers, since we have full access to that source code. One option that I read about that we could potentially do is write a wrapper for the *adreno200*so librares that would implement the newer API that ICS is expecting and would translate the calls into the older API that is supported in our GB proprietary drivers.
It looks to me like we have two possible ways forward with regard to getting hardware acceleration working: upgrading the kernel and drivers to have "proper" ICS support, or patching ICS userspace code to work with GB drivers and kernel. I believe that patching the ICS userspace code would get us up and running faster while upgrading the kernel and adding newer drivers would be the better long-term solution.
Here are a couple of patches that people have already implemented to support older EGL blobs/kernels:
https://github.com/VorkTeam/android_frameworks_base/commit/429e922fb6f2660fc40472e939175688af52b1d2
https://gist.github.com/CyanogenMod...mmit/5d689bd02531f8ff256b3b1eddcaa8040c9f3559
https://gist.github.com/CyanogenMod...mmit/f8e2430be2d6b3e88afd7190f6712f3bc1df0cbf
Let me know what you think.
Also, what do you think about using the BOARD_USES_QCOM_HARDWARE := true directive to our CM board configuration? I noticed references to the QCOM_HARDWARE flags all over the video code. It seems we would want this since we are using a QCOM video chip. The only problem is the build failed for me when I added this flag. There's an issue about it on github: https://github.com/CyanogenMod/android_hardware_qcom_display/issues/3#issuecomment-3457179.

Let me know what you think.
Also, what do you think about using the BOARD_USES_QCOM_HARDWARE := true directive to our CM board configuration? I noticed references to the QCOM_HARDWARE flags all over the video code. It seems we would want this since we are using a QCOM video chip. The only problem is the build failed for me when I added this flag. There's an issue about it on github: https://github.com/CyanogenMod/android_hardware_qcom_display/issues/3#issuecomment-3457179.

Unofficial nightlies?????????????

I dunno I seem to remember there being Nightly's and stable releases. Now we have Unofficial Nightly's. Why? This isnt going to continue is it? Eventually we will get back to just Nightly's and Stable right? Not that its a big deal just seems unnecessary.
As I look through the threads I see there are a good number of people running these Unoffical Nightlys so maybe someone can explain to me the difference between Official and Unofficial. Are they that bad that they cant be official? If they are that bad why are so many people running them? Seems to reason that the unofficial is stable enough so cant we just make them official for god sakes. I mean really whats the worst that can happen? Its not like Cyanogen is going to be sued. Its already assumed that official nightlys are not going to be stable so whats the problem?
Official is being built by the Cyanogen servers and released at their discretion. The unofficials are users creating their own builds (usually with modifications) and being released separately.
That being said, CM7 has been in development for a while so there are both nightlies and stable releases. CM9 is still in early development, and Cyanogen team hasn't been releasing nightlies yet. The ones you see are users releasing it on their own.
You're either not very smart or a terrible reader. Unofficial simply means private individuals are taking it upon themselves to regularly post private builds that they made themselves, for others to take for a test drive. Official builds would come directly from CM, which has not happened yet.
Get a clue.
Perhaps your highness would be kind and gracious enough to direct us to a place where we could read that explanation (assuming, of course, that we can read such lofty material)..
Tongue firmly in cheek.. but.. hey Dude.. lighten up.

I'm kind of confused due to your confusion
What "Unofficial Nightly's" and "Official Nightly's" you are seeing?
Don't tell me that you are confusing the Official Nightly's of CM7 and the Unofficial Nightly's of CM9.
Two different things.
Im sorry! Im trying to keep up with the development of the Nook Color, HTC Droid Eris, and the Galaxy Nexus and I lost it. LOL Not too mention my search for the perfect router to finally rid me of that god awful Linksys WRT54GS combined with the overkill Smoothwall finally ended. My home network has been in shambles till recently. Again I apologize. Its purely my mixup and clearly nothing to do with the information provided at XDA. I just needed to search a bit more. Or I could have asked like I did here but maybe in a more positive tone. Im sorry for that as well.
So I recently purchased the GNEX and I love ICS. OMG I cant tell you how nice it is to finally have a proper smart phone with polished Android Goodness. I want the same for my Nook. From what ive read so far the "Unofficial Builds" seem to run pretty good. Users reporting it runs as good as CM7. Is this true? I mainly use my Nook for watching Netflix and Hulu. I do some light browsing as well. Would the latest build work well enough for me to hop in now?
Thanks for your help and understanding!
I don't know how far but CM9 is far from stable as CM7

Awesome. Reading comprehension skills FTW.
CM9 is nice. Personally, I'd wait for solid wifi and any true resolution on HW accel.
CM7 had 'official' stable releases and 'official' nightlies built by the CyanogenMod automated build process. The last stable was 7.1 but there were nightlies after that which continued to fix some remaining problems.
Back in mid November 2011 the build process suffered from some hardware failures and the nightlies stopped appearing. At the same time ICS was being released and the devs switched their attention to that (CM9) and, although the build process got repaired, the CM7 nightlies were never restarted.
There were some outstanding issues in CM7 that had got fixed but never built by the official process into either a stable or a nightly. That is where the 'unofficial' builds stepped in and built new ROMS from the source incorporating the latest fixes and including some other improvements. The most common of these is the MiRaGe build found in the thread in development and that has been very stable, gives great performance and is often referred to as 7.2
CM9 is effectively still in an alpha form and does not have official nightlies or 'stables' yet. The developers did encourage people to learn how to build ROMS from the source and some have now made these 'unofficial' nightlies available.
Some find these unofficial CM9 nightlies good and stable enough for daily use; I am one. There are trade offs; the CM7 ROMS are generally a bit snappier in performance and there are one or two limitations in CM9 functionality (e.g. hw video acceleration) but this is balanced by a significantly nicer user interface and functionality in CM9. You just choose based on what is important to you.
Nandroid backups are always your friend and allows you try out various options at low risk and just a few minutes to fully restore to a former point.
Thanks for the summary and info.
But how well does Hulu and Netflix work? Right now thats the most important thing.
Im currently running CM7 stable with the processor clocked at 925. I see alot of people running overclock kernels so when you say CM9 isnt as snappy to which are you comparing to. Low end or high?
Either. I'm running CM9 at 1200 right now and there is still lag (haven't done any tweaks though, working on other things). Besides that, I don't think Netflix is working on CM9 yet. If you are wanting stability, smoothness, and more application compatibility, CM9 isn't quite there yet.
It's funny how the people calling the OP clueless seem blissfully unaware of the situation with nightlies the last few months, but bobtidey broke it down well. The automated system for CM7 nightlies is broken, but the updated source is still available, and some people are sharing their builds from source (MiRaGe being the most reliable atm).
If Hulu and Netflix are your priorities, CM9 is probably not for you just yet. You can try it out a number of ways,
As bobtidey said, back up your current build, flash CM9, and if you're not happy go back.
Set it up on SD--there's a link in my sig for that, just grab CM9 and a compatible gapps instead of CM7.
Repartition the NC and set up a dual boot like mine (also linked in my sig) with MiRaGe's CM7.2 and Samiam's CM9.
If you just want a fresher flavor and don't want to mess around too much, I'd say go w/ MiRaGe's build.
Blah! It is what it is. As stated things have been pretty hectic around here. Now that I think of it things are always hectic. So I overlooked something and needed correction.
I just may dual boot. Ive wanted to try MiRaGe for awhile now anyways. I hear great things. Should be a nice upgrade over CM7 stable right? Thanks for info!

[Q] ICS Progress: TexasIce vs BCM

Heyo N1 community,
I had a quick question regarding the ICS race.
Right now, probably like many of you, I'm paying a lot of attention to the progress we're making towards a fully functional and stable ICS ROM. Looking through the forums, it seems like there are two versions that are the most complete: BCM, which is based off the Bravo CM9 repositories, and TexasIce, which seems to be a hodgepodge of fixes and is,nonetheless, an AOSP ROM.
Judging by their respective threads, it looks like TexasIce & Evervolv are blazing the trail in terms of bug fixes, with the only real bug remaining being a camera FC when trying to record video.
My main question is: is this assessment correct? Is TexasIce/Evervolv the closest we are to flawless ICS right now? Or is BCM neck and neck with it, or possibly even more polished?
I'll say I've always preferred the CM team's work, and that's why BCM seems so appealing to me. Does the Evervolv team have the same resources and manpower, or are they just making up for both with lots of really hard work? Are they able to use and build off the CM9 source?
Thanks for any insight/info on these matters. I always prefer to be informed and I appreciate any help in that endeavor.

just looking for some good objective info here fellas.

[Q] What's your favourite ICS for Nexus One?

Rom Port Team Effort - Let's bring a diversity of roms to our P880.

Rom Port Team Effort
Hello P880 community.
This post has the purpose to put together a group of users / developers, who are willing to participate into bringing a different set of roms into our community.
These set of roms that I'm thinking, can range from complete Sense ports to more customized and maybe less popular roms (like ColorOS, LiGux, FlymeOS, FluidUI, etc..).
What's valid on this thread:
- CM / AOSP (any base we already have) themed (like Samsung TouchUI, Optimus, Blur, etc..). So you can grab any rom (with author authorization), theme it (i mean, not just shove an apk as default theme, I mean neat theming ).
- Ports from other devices (evert port needs to have clear authors permission to port it).
- All users are very welcome, everyone can participate, users with porting / developing skills are needed as well.
The idea is simple, we're not going to use this thread to post the work, this is just a thread to talk about possible projects.
We can start by listing which devices are hardware compatible and the port is "easily" possible.
Roms that can be used as a base for eventual future ports.
CM10.2 - thanks to laufersteppenwolf for compiling this build promptly for this purpose

I strongly recommend the use of MultiRom for testing ports and other roms. That way you can maintain your working rom and whenver feeling adventurous you can without going through the hassle of backup / restore / yada yada yada that we are all too familiar with.

Well, I though about some sort of "voting" to bring a "specific" rom.
Personally, I'd love to have Sense on our device. I had two HTC's before and I miss that Sense interface :b
But far as I'm aware, isn't an easy thing to port.
About your offer, this thread stands mostly with learning. The idea is everyone being able to contribute and more users start bringing roms as their first times. So, thank you so much for lending your help and know how, I'm sure we'll have a fine list of possible ports and then we can talk about how to port them over
Everyone can ask for help and the idea is to everyone who is able to - help.
I like the idea of this thread, but what would also be quite usefull is a list of available ROMs and their maintainer(s).
Also the list should include ROMs someone is working on ATM, so it cannot happpen that 2 devs are working on the same ROM
However, your idea is good, but porting a ROM not from sorce is quite hard, and might need some smali "hacking" in order to resolve bugs.
But well, we're a community, and I guess we can help each other if needed, right

That's correct! :good:
The main point is to learn helping each other who knows in a month or so, today's whiners are tomorrow's contributors
Jokes aside, the first post will be edited in order to structure and add information.
I'm gonna start with compatible devices (the ones that allow porting in a easy way). Ideas? Besides the HTC One X ? I'm guessing the grouper (N7 2012) besides having the same soc, doesn't have the same screen...
PS - (this would be better with an experienced porter) - Maybe we could start with a easy one, and go on from there
I know we have "how to port" threads all around xda ,but each port is different so we can't use "one hat to fit them all" ... or a ring to rule them all, so we should treat each port differently.
However.. I'm gonna put some xda links about porting to bring some light into the matter for who is "new" on this subject... or for whom's feeling adventurous and can't wait to have "their" rom on "our" device
Oh yes finally, have been waiting for a thread like this for a long time me as well would love to see a sense rom on this phone
cm/aosp roms are not that hard to port most of the time u only need the same screen resolution for it to work. (ported a nexus s touchwiz rom over to my old lg optimus 2x) but would have loved to see some oem roms ported over as well, even though it would be a lot harder to port over. but as a wonderful community as this is we might be able to pull it off

You can add the HOX+ to the list as well
About porting, you need to seperate it in two halfs, porting from source, and "winzipping". TBH, I'm no fas of winzipping at all, but some stuff (like sense or TW) can only be winzipped...
BTW, if you need a 2nd/3rd post, just let me know
Personally, I'd like to see a GFlex or even better, a G2 (/mini) ROM for our phone (KitKat, of course )
This thread has potential
I'm new to this forum,so i dont know whats going on about roms,i see there are few devs working full time.
I think this is the best way to go: Port ALL open source roms,such as we have already,but we need them all.
Second,make a badass kernel,with all features and customizations,possibly 3.4.
Third,and just a suggestion,Make a community ROM?
I really like this thread,and i even more like this OX4 community,you all get along,and i've missed that,i was on a forum that has no frendly people whatsoever.
And,about the roms,the idea is awesome,but i always think of the clash of clans rule,max everything out before going on a higher level.

Regarding stock roms, it's an interesting thing, but I'm guessing stock roms are more trouble to port comparing to AOSP or CM.
I remember on the HTC Sensation forums the headaches sense brought to many developers and porters, the bunch of files that needed to be edited, kernel changes (aosp kernel is different from stock / sense kernel in that case).. so Stock roms are maybe harder to port fully.
Right now we have some apks from the G2 (lock screen, messaging, etc..), maybe someone will port some things from the Flex, but the whole base.. hum
@DeHuMaNiZeD , thanks for your reply
The other roms based of AOSP and CM, in my opinion, unless they're different (modded, themed, customized - etc..) but if not, if they are "clean" roms with no changes, then - we have them already I believe you'll agree. (Unless the idea is to test something).
A 3.4 kernel would be something, but perhaps a developer can shed some light here - what benefits would we have from a 3.4 kernel ?
A community rom is indeed long due. This thread is a different subject because it's about *several* roms, ports and tutorials, maybe you would like to create a thread here on General about that? You can start with votes (i believe it's a proper way to do it) with which base should we use (Cm, AOSP, Stock, etc..), included apps (or not), possibly aroma maybe and so on

Well, this sounds quite good, but the real problem is: this is a hell lot of work. Also, it needs resources. The sourcecode of a ROM is ~25-30GB. When it's compiled it's about double the size, and takes my PC (8 cores @ 4GHz) about 75Min to compile. Not to mention the time 'til the sources are Downloaded. My 500GB HDD is near to its limit very soon, so sooner or later I will need a new HDD, then I might be able to get another ROM ported, but right now, hard...
Also, why do you need a 3.4 kernel?

For stock ROMs to work, it's your best bet to use AOSP as your base, and then look for what's missing/broken. This, however, means you need an AOSP base first to work with. And AOSP is not always the easiest thing to get properly running.
About the benefits of an 3.4 kernel: None IMO. All you get is a higher version-number, and that's it. We actually already have some 3.4 features backported, and also tweaked the 3.1 kernel quite a lot. So the actual benefits are all in your head (well, except you count bugs as benefits )
Community ROM? Meh, what for? We have so many ROMs already, so everyone should find the one that suits him/her best
BTW: Thread stuck

Why dont you set up that build server,i think they're cheap atm,or someone could borrow you? It would take a lot less time and effort. that's why i think offical rom support is important,once it's merged to the build bot,its their responsibility.

It's not as easy as you might think
I do have access to a buildserver, however I only have 100GB as it's a shared one, so this is genious for official builds, or quick tests/ports. But it isn't ideal for the long terms.
Also, having it official doesn't mean you're done you need to update it, and also fix it when it's broken. 'cause when it's broken, it can mess up the whole build process of the buildbot
But in general, you're right, having it official does help a lot

Nope, I actually never "winzipped" a ROM
Lot of things to comment on here. Very good initiative I have to admit. I'm sure I'll have more ideas as the discussion evolves.
Similar hardware: You can add HOX+ as laufer said. Very minor differences are there only.
What I would personally prefer is TouchWiz, at least Nature UX 2.0, but new S5 UI is also really awesome. I liked Sense till 4.5, but 5.0+ versions are now out of my 'inner circles'. Especially what I don't like is the UI.
Few suggestions:
FlymeOS (from Meizu MX) - I got 2.0 booting last summer, but had touchkey issues (they were freezing the device lol) and never released it. Nobody ever booted 2.0+ on other Android devices yet.
Porting LG roms might be the best start, I think porting full Optimus G system wouldn't be that hard. Just a pain in the *ss merging process.
What we mainly need is same screen size (unless you wanna resizing 100+ apps ). Similar SoC is a good extra, but that's very limited. Also, it's better to avoid Qualcomm SoCs to port from, it's extremely hard, there are a lot of code changes in low-level code which just make the device get into deep segfault cycles. :cyclops: Even Exynos is easier to port from, trust me. I got SGS3 leaked 4.2 booting on the O4X last autumn.
Big issue we have to note: In 4.2, Google radically changed graphics libraries code. We have old, 4.1.2 blobs and those need hacks in libgui.so and libsurfaceflinger.so to function properly (in 4.4+ libEGL.so, libGLES_v1_CM.so and libGLES_v2.so also need a change). Here comes the problem: Manufacturers do change these libraries, mainly adding Wi-Fi display and HDMI support code which other blobs rely on. Of course we can't just replace these libs, graphics wouldn't function that way. Either we have to guess those function signatures and reimplement some stub in the code, or use new blobs, i.e. what I did in Omni. But y'all now those are not perfect _yet_.
Regarding newer kernels: If, I emphasize, IF it's properly ported, it would cause a noticeable effect on overall performance, battery life, etc. What do I mean by proper porting: All machine-specific code must be updated to Nvidia/Google upstream, no excuses! I don't say anything for sure, I didn't check it much, but kholk didn't do this merge. His kernel still uses 3.1 files with slight modifications to be 3.4-compatible. What I mean would be a very long and painful process, but would surely benefit after all. 3.4 has no Android branch, mainline Nvidia Tegra kernel does only have Linux support, it might be even harder. 3.10 is maintained by Google for Android, issues I have found so far: No graphics driver support for T2 and T3, have to forward-port it and I didn't find core Android components like wakelocks, earlysuspend, etc. Weird.
A little related story: I initially started working on MultiROM so I can test and port different roms while I can keep a stable rom for myself and there'd be no need for reflash then. That's what I can suggest. Use MultiROM, it has so many capabilities! Maybe it's better with kernel sharing so you don't have to wait for hardboot on every reboot (which one needs a lot if porting). @MidnightDevil you could add this to the OP maybe.

I can't find them either, but I'm on a tablet so I can't look properly.
@laufersteppenwolf, do you have any *spare* 4.3 build?

Here you are! Compiled this because wanted to start porting from Note 2, but finally worked on Omni more and abandoned it.

BTW, did anyone tried to port a ROM this way? http://forum.xda-developers.com/showthread.php?t=2245786

That's way too generic unfortunately.
Quick suggestion for you port: Use Note 2 base with Note 3 features. Note 2 has the same resolution and you won't need to resize.

Lot of things to comment on here. Very good initiative I have to admit. I'm sure I'll have more ideas as the discussion evolves.
Similar hardware: You can add HOX+ as laufer said. Very minor differences are there only.
What I would personally prefer is TouchWiz, at least Nature UX 2.0, but new S5 UI is also really awesome. I liked Sense till 4.5, but 5.0+ versions are now out of my 'inner circles'. Especially what I don't like is the UI.
Few suggestions:
FlymeOS (from Meizu MX) - I got 2.0 booting last summer, but had touchkey issues (they were freezing the device lol) and never released it. Nobody ever booted 2.0+ on other Android devices yet.
Porting LG roms might be the best start, I think porting full Optimus G system wouldn't be that hard. Just a pain in the *ss merging process.
What we mainly need is same screen size (unless you wanna resizing 100+ apps ). Similar SoC is a good extra, but that's very limited. Also, it's better to avoid Qualcomm SoCs to port from, it's extremely hard, there are a lot of code changes in low-level code which just make the device get into deep segfault cycles. :cyclops: Even Exynos is easier to port from, trust me. I got SGS3 leaked 4.2 booting on the O4X last autumn.
Big issue we have to note: In 4.2, Google radically changed graphics libraries code. We have old, 4.1.2 blobs and those need hacks in libgui.so and libsurfaceflinger.so to function properly (in 4.4+ libEGL.so, libGLES_v1_CM.so and libGLES_v2.so also need a change). Here comes the problem: Manufacturers do change these libraries, mainly adding Wi-Fi display and HDMI support code which other blobs rely on. Of course we can't just replace these libs, graphics wouldn't function that way. Either we have to guess those function signatures and reimplement some stub in the code, or use new blobs, i.e. what I did in Omni. But y'all now those are not perfect _yet_.

Dang, you've beaten me but mine's as fresh as it could be
HERE you guys go, for all who need the newest CM10.2

Just don't delete the sources, you might need them in the close future.
I think we should create a schedule about what to do. As you all know, good buildings all have good grounding. So let's get started from the very beginning I say. First fix remaining bugs in MultiROM, then create a unified kernel so users don't have to choose. Very likely this is not possible as people think different so just make all kernels hardboot compatible. After these we have a solid base for starting all the work. Of course this cannot be done if not everybody is involved. Both devs and users should share a part in this magnificent journey.
(High expectations, I know. )
