Why is there such alot more development and forum activity on for example the Xiaomi Redmi phones than on this one? The p9000 got excellent hardware for a great price but the community is really small somehow and the software is still buggy? How come? Do you think its still worth to wait for more activity and responses from developers for this phone or is it a "dead cow" already and better to swap to another brand to get support from developers on for example CM or RR?

Development for this device is far from dead, we have a stable device tree for building custom ROM's, CM and RR ROM's already released, a fully source built TWRP and work on custom kernels is just beginning. That's a lot more development already than an awful lot of devices see in their entire lifetime.
I would rather say it has just begun. Development for this MTK chip is not a matter of course and the outcome so far is pretty exciting. This opens the way for other devs who work on other devices with the same chipset. It's just that many devs simply prefer Snapdragon which leads to higher dev count on those devices, faster bug fixing etc. I am pretty excited what the future brings not only for our P9000 but MTK devices in general as far as flashing and development goes.
Development is dead? What gave you that impression? For starter this phone already has a working twrp recovery. That is more then some Chinese phones get in their whole lifetime. Kernels is the area of development next and elephone has been kind to release the source code for the phone. Again more then most developers even bother with.
well, it got twrp,root and xposed working. More than some name brand phones that stop official updates after a year.
But i admit it is easier to update my old nexus 4 with cm downloader. Just click the update notification and latest cm gets installed.
It is also getting nougat in November hopefully

That's because Nexus 4 is an officially supported device by CM.
It's very difficult for MTK devices in general to get official CM support because we have to patch some things in the framework to make camera, RIL (mobile data) etc working.
The official stance is that these things should be done in device tree as no proprietary code is allowed in CM framework.
Initially when our patches were submitted to CM Gerrit they were rejected because of this, Leskal is working on minimising the patch work needed and getting more of the generic MTK code accepted on Gerrit.
Not helped by the fact that MTK themselves aren't helpful or willing to support developers as it doesn't suit their replace and force upgrade business model. Technically how they operate and their refusal to release official development tools or code is a violation of the open sources nature of Android. But google has yet to do anything serious about it. As far as I know, any code we have is from reverse engineering and leaks.

Not true, I've met up with MTK engineers at DevCon and they do actually encourage development, they just seem to lately be wanting to protect their HAL's and drivers which as pointed out on the XDA portal article about this is sort of ridiculous. But then again it's proprietary code and not under the GPL so whilst we can say it's stupid we can't really contest it, it's their choice.
The code we have is completely official and not gotten from reverse engineering.

Why do they need to? There's already great tools around for that, I know Qualcomm certainly used to provide a package for debugging the lower system levels but it wasn't widely available as the lower levels of the device booting process are not needed to be modified outside of OEM labs and manufacturing.
The lowest level we need is kernel debugging and the kernel already provides that via last_kmsg and desmsg etc, all other tools are already available as part of ADB, logcat etc. There are also a plethora of other tools readily available.
I would call it pretty dead now Well, if not dead then dying.
Let's hope for a Christmas special

Hello!
I see all these advices on making a ROM. But these advices and the issues they deal with are IMHO not the real issue. If you have a Nexus One phone and want to modify the Android OS there's nothing stopping you. It's "easy". It's all "there".
But what if you have a new Android phone which has proprietary driver code and made by a company that has NO interest in sharing it's code or make it easy for you to root your phone? Making ROMs for these devices is the interesting thing to talk about. Otherwise you can change the name on this forum part to: "Make ROM = *.android.com"
So these two issues are the most important ones IMHO:
1) Devices DO get rooted. So some people must know how to get there. I assume that there is no "one way" of doing this but it would be nice to discuss this and make some sort of a list on what to THINK about.
Many devices will never get rooted because the brand is despised here. That is why it would be good to have some general knowledge so others that ARE interested in these despised brands can take action.
2) You have a rooted device. You load a standard Android OS ROM. All proprietary drivers are lost and thus many features and maybe whole hardware units are unavailable to you. How do you locate and use unsupported hardware in your ROM?
I understand why many "elite" devs have a Nexus One since there are no propietary driver code in that one and rooting was easy. So the doorway to the Nexus One Kitchen is wide open. But what about the rest of the new Android phones that are out and will come. Why don't you discuss and explain the general thinking in rooting a device and finding/using hardware/features that are lost because of proprietary driver code.
Thanks for your time

+1. i don't even get his problem tbh.
Hi all,
I am noob at XDA. (About myself: I am a software engineer aged 30. I have been hacking computers since I was 10.)
I am here because I am planning to buy a new Android device soon. (And unless something really revolutionary happens, I don't plan to upgrade it in the next 2 years or so, so it's a long-term decision.)
My short-list is:
- HTC One S
- Sony Xperia S
or, if everything else fails:
- Samsung Galaxy Nexus
The hardware of the One S and the Xperia S is obviously more powerful than the Galaxy Nexus; my only concern is the software side of things.
The thing is, I really don't like the customization the hardware vendors do with the software, so I want to run raw vanilla AOSP, or something very close to it.
(CM definitely qualifies.)
Also, I am sick of waiting for ages for new android versions to be ported to my device.
Obviously, Galaxy Nexus is guaranteed to be get Android upgrades first, so that's a safe choice in this respect, but since I like the hardware of Xperia S (and One S) so much, I would like to gain a better understanding the software situation of them, so I can make an informed decision about my purchase.
I am aware of the fact that Sony is actively supporting the Free Xperia Team, which is bringing CM9 to Nozomi (among other devices), but I have no information about the details of the project, or it's limitations.
So, my questions are the following:
1. What is the exact nature of the support Sony is providing to the FXP team? (HW? HW docs? Binary drivers? Driver source? Consultation?) Has this changed in any way, now that Sony Ericsson has become Sony? Was this a one-time action, or have they made any commitment about the future?
2. What does one need to build a vanilla android ROM for the S, using the AOSP sources? (Let's forget Cyanogenmod for now.) What is the status of the required device drivers?
3. What are the current obstacles, hindering the release of CM9 (or any other derivative of AOSP) for this device? As far as I know, Nozomi was released in 2012.02, ~4 months ago. ICS was released in 2011.10, ~8 months ago. Official ICS (Sony's version, with Timescape) is rolling out about now; CM9 is not yet released. I wonder what is taking so long?
(Please understand that I really, literally wonder: I am not demanding anything, and I am not trying to offend or accuse anyone; I am totally aware that I don't understand the process; I would like to have more information to understand what needs to be done. And since I am software engineer, and I am not afraid of getting my hand dirty, so eventually, I might end up helping with it...)
4. Do we have any information about Sony's plan for this device beyond ICS? Jelly Bean is coming up soon. Regardless of Sony's decision, when JB is released, I would like to run it on my device, as soon as possible. What are our prospects for porting JB to Nozomi? Is Sony going to help with porting the device drivers to the new kernel, is something like that would come up?

1) No one knows for sure, but I'm pretty sure that it's not game changing, judging by the progress me and Doomlord made on AOKP without any help from Sony (obviously).
2) You can try building Gingerbread, but no one cares, right? For ICS, see the next answer.
3) The most important problem is that we don't have the drivers/kernel sources, and there's not much motivation for building it from scratch considering the soon(ish) ICS release. There are leaks with files for so called 'brown' or developer devices, but they also don't give much because of different low-level software. So the state of things is that almost everything but wireless is working, but wireless doesn't work at all. That means data, calls and WiFi.
4) JellyBean will likely be a minor upgrade (4.1 that is) and there's nothing stopping Sony from releasing anything on the 4.x branch. When 5.0 comes, it will depend on the hardware requirements but I'd guess we're getting it too.

There are kernel sources for GB, the same ones from which the stock kernel was built. If you mean the upstream Linux kernel, it'll be a huge diff that's not so easy to port without datasheets (which we don't have) and actual understanding of how the hardware works. Speaking of drivers, I'm pretty sure you misunderstand the way Linux / Android 'drivers' work. Kernel-space drivers (modules) and userspace drivers (libraries and daemons) are two different things. They have to open source their kernels because Linus's tree ('official' Linux) is GPL, but the userspace parts are proprietary. ICS also brought many ABI changes, so just taking old libs and placing them in a new ROM often doesn't suffice.

They add some stuff, but they also change stuff internally. Tweaks and patches and many different things to get the best performance on this specific board. CAF has a generic msm-3.0 kernel, but that's not as customized. And we're not really waiting for the kernelspace here.

Actually what NVIDIA does is ship a GPL'ed kernel module whose only function is to set up an interface through which the userspace (libGL) can talk to the hardware. So their kernel module is open source, but all the magic happens in the proprietary userspace.

Android has a HAL of its own, so mostly it's about HAL modules, libGL and libril (Radio Interface Layer) to talk to the modem. And here is where many hardware vendors pull an NVIDIA.

No, the kernel isn't that much of a problem. If we have to wait for too long, we'll just take CodeAurora msm-3.0 and port it which shouldn't be too hard cause it's as generic as possible.

Hello All,
As you all know I've been part of Xda and assiting in a positive resolution from HTC in requests from Bootloaders to source codes. Well seeing we have a great device that seemed to be given EOL to early in its game.. in my opinion due to lack of marketing skills. Well I will be posting in HTC FB to get our voice out to them for the Source Code release for our device.
Please comment "Like" and comment to request this so we can continue development for the Flyer.

Um, source code of what? They release sources of Honeycomb, and there are no sources of ICS or Jelly Bean, so what's the whole point?
Source code for drivers which can be ported to ICS and JB. Anyway it helps coders make their own drivers for Camera/Front camera and for video

Then we're asking the wrong ppl, it's not HTC. to understand this first you need to understand what makes up a ROM.
There is the kernel which is low level device specific, the kernel is mostly based on open source linux code, htc adds some board and device specific configuration on top of that.
Then there is the aosp which is also open source, an operating system provided by google that makes up most part of any ROM.
Then you have your aosp derivative like CM or AOKP, which provides board specific fixes and some customization. HTC's ROM is also based on aosp, but they add their own sense look and feel to it.
And finally and most importantly you have your close source proprietary drivers provided by chip manufactures like Qualcomm and TI. They control cameras, wifi, BT...etc. So in reality there is very little HTC could do as they don't have the rights to release these code. And that's is where most ppl run into issues.
So to create a ROM is not hard at all, anybody can download the source code and compile it to generate a ROM as most of the source code are all open source. What will be helpful is if Qualcomm releases the source code for their drivers, which I doubt they will ever do, otherwise they wouldn't be close source in the first place. The only thing we could do is try to reverse engineer the device base on logs and understanding of how each component should work and make educated guesses.
Due to HTC lack of effort on this device (No ICS - HC was slow joke) I will never buy another HTC product again, same goes for sony, though they did eventually update xperia x10i it was only due to huge pressure not because they wanted to.
I want to buy an electronic product that potentially remains relevant at least a year later otherwise forget it.
so i sent this letter to HTC
after reading this page where HTC discusses 4.1 upgrades i decided to drop them a line "
DIRECTLY FROM YOUR WEBSITE:
When will additional devices receive Android 4.1?
In addition to the HTC One X and HTC One S, we are actively reviewing our product portfolio to identify candidates to receive Jelly Bean. Our goal is to prioritize review for devices launched in 2012 with our numerous carrier partners across multiple regions and then consider our ability to provide updates to products from 2011.
What devices will not get Android 4.1?
We work hard to ensure each of our products has the optimal user experience and therefore some products will remain at their current version of Android. In general, devices with 512MB RAM or less will not be upgraded to Android 4.1. At present, these devices include the HTC One V and the HTC Desire C. As we identify other devices that will not be upgraded, we'll provide updated information.
What about a development version of Android 4.1?
For our developer community, we plan to make generic development ROMs of Jelly Bean available for both the HTC One X and HTC One S. As soon as the ROMs are ready, they will be posted to our HTCdev site (www.htcdev.com). We strongly recommend customers take the time to understand the limitations of the development software along with the terms and conditions on the site before downloading to their device.
REALLY!? have you listened to what your customers have asked/said about the HTC flyer at all?! where is OUR 4.1 DEVELOPMENT ROM! wtf! where are you for us!? I can tell you where... you are giving us 3.2 HC that takes away two very important features i bought the device for #1 GPS! completely broken by your newest update to HC. #2. Hardware Keys.... WHY?! i understand that HC introduced soft keys. so you say you "We work hard to ensure each of our products has the optimal user experience" BULL! you clearly weren't thinking about the end user when you pushed out that HC update for the flyer. Would have been smarter for you to leave us on working GB and go straight to ICS or JB when it was ready! this is lunacy! who ever is making decisions in your company needs fired. you are bleeding money from everywhere. why don't you bring it back to the old school HTC that CARED! ABOUT! IT'S CUSTOMERS! listen to what we are saying! hear our voice! we have signed petitions. we have pleaded on multiple forums. WE have poured over your FB and twitter pages asking for you to throw us a freaking bone here.... when is it gonna happen? ever?!
I still have my flyer and i love it dearly. but without updates it's falling behind the pack. I recently bought a 10.1 galaxy note. while i'm happy with it's speed and what not. it's not the form factor i want. which is what the flyer is for me. perfect. PLEASE DON'T GIVE UP ON US OR THIS DEVICE! PLEASE RELEASE A DEVELOPER ROM FOR OUR FLYER! "
this was their reply (you will want to read it for sure)
Dear Matt,
Thanks for contacting HTC!
We completely understand your concern and I thank you for your patience and am deeply sorry if this issue has caused you any dissatisfaction with HTC or its phones. I hope that it will not detract from your overall perspective of the device or the company. You are the most important part of the HTC Family.
We listen to our community and feedbacks like yours are the ones that make us revise our decisions, and try to find the correct balance between the device’s performance and usability. We cannot announce or say anything about the Flyer right now but what I can tell you is that we are, indeed, paying attention to the community´s feedback and opinions.
Should you require further assistance, please do not hesitate to contact us through http://www.htc.com/us/support/email-support or call us at +1-866-449-8358 from 6AM to 1AM EST, 7 days a week.
Have a great day!

I appreciate the passion here, but HTC left this device for dead along with the Jetstream and View shortly after releasing it. We received what would amounted to a Beta of Honeycomb then they closed up shop. You live and learn, and although I still use my Flyer and enjoy it I will not buy another HTC device
I completely agree with you .. HTC should give us ICS or JB for our Flyer as a good faith. We must keep GB because honeycomb is a joke..
I use my Flyer and i try as much as possible with the optimized news on GB .. and share with you.
Hoping for a good action on their part for JB!!

You didn't understand I think. The drivers are part of the kernel. May they be compiled into the kernel itself or in form of modules. Drivers can be binary objects to be linked (already compiled) or source code which will be compiled when the kernel is built.
If you have the drivers source code there is a fairly good chance to get them running in newer kernels with some minor changes.
So from my point of view you will have a good chance to even get 4.2 up and running as long as you have the drivers source code.

yeah, so my point is HTC publishes kernel source code, not drivers, they don't even own some of the drivers .,so you will never get that. You get a HC kernel ,that works with a HC blob set and you cannot build a working 4.xx kernel because you don;t have a 4.xxx blob set and HTC won't give you one because they have never written one and never will

well they must be of some good since we have ICS/JB ROMs out there that are "mostly" complete, slick and usable, although slightly buggy, so obviously yeah i get that it doesn't solve all the issues we have, since some drivers are missing: as evident by the non-working FC, no hardware decoding for video, and semi-working BT
DigitalMD said:
yeah, so my point is HTC publishes kernel source code, not drivers, they don't even own some of the drivers .,so you will never get that. You get a HC kernel ,that works with a HC blob set and you cannot build a working 4.xx kernel because you don;t have a 4.xxx blob set and HTC won't give you one because they have never written one and never will

Not exactly. The kernel is also part of AOSP. And even if HTC does not supply the driver sources there is a slight chance to use old driver binaries or to have them reverse engineered by some genius dev. Hope is the last to die

Keep dreaming. Some of the best around have tried that path.
No the device kernel is not in AOSP, the base linux (ANdorid) kernel source resides there, but if you look at the build, it calls in device , vendor, OS verson and board specific components to make a complete build. All that hooks into the blobs (drivers and libs) to make up the device specific environment that allows Android version X.XX to run

Thanks for clarification. So I was not wrong about the drivers, which are the device and vendor specific components. In other words if you can get the vendor to release their sources or make their chip/board manufacturers to release their sources is the only way to go. Seems a bit unrealistic though but who knows...

Yes yes, you may think that I'm crazy for attempting to compile AOSP, but in fact im just obsessed with getting AOSP to work (on my previous device I spent a full year on it without success), thanks to the experience I know much more know about the environment.
I've done several pure aosp builds so far, and they result in a ~280mb system folder, which is kinda the size of aosp I guess (atleast for xxhdpi)
But they end with errors of course, anyways. I used the devices specs with updated overlays,and added dependencies (such as hardware) to the environment.
But since the aosp environment is very mean to new devices its once again a real struggle. as expected, but I like the challenge.
Anyways, Im currently trying out this hybrid-ish environment. which contains the items listed above but with several elements of the AOKP environment added (only the essential ones for compatibility).
Compiling goes so far so good. hope I will get a working build. (don't expect this to happen tho)
Oh and since samsung is releasing the S4 Google Edition (AOSP) soon it must be possible. (the google edition is the qualcomm varian afaik)
More info soon!
I'm going to drop this here for now until I have time to mess with it more.
https://groups.google.com/forum/?hl=en#!topic/android-building/_F67iLDcVzQ
Note: This leads me back to my previous question as to how we are supposed to build with this.
At face value it seems we're only getting fairly close to what we were with other OSRC releases.
Going to look at more later tonight.
Skilled devs can get pure aosp to work properly. It was done for sprints gs3 without using CM code.

You don't necessarily need proprietary binaries to be released to build AOSP, although it does make it much easier. Sometimes you have to resort to trial and error and debug tools.

I disagree completely. Without the prop' libraries and drivers that the OEM has built to manage the board you can most certainly expect the related hardware to fail or be only partially functional at best. Some other 3rd party generic driver would still be required if this example were true. In the good old AOSP days (maguro for example) had roughly a dozen proprietary files required for the device tree to build. With more and more OEMs making different hardware configs and spin-off APIs trying to lock down a lead in the game it has inflated that number greatly. In this instance, for example, S4 requires roughly 165 proprietary files in the vendor/ and device/ tree. Furthermore, with many of those stacks being required to pass for a successful boot complete (audio for example) there is little chance for even semi-functional usage without the required libraries and drivers.

We're compiling pure AOSP already for this board. I'm not sure what your repo structure looks like but if you are based off a CM or AOKP base clone then you got some work cut out for you. The CM tree compiles completely different than AOSP. All EaglesBlood builds are compiled from our same main branch, which consists entirely of only pure AOSP + our own EB coding. There is no CM codeblock nor anything else polluting (no pun). Since CM and others have some custom hybrid APIs and such you may run into issues that are difficult to resolve or even identify. If you aren't the one committing those patches then it is difficult to know at a glance of what has been heavily CM-ified vs closer to native code; or unless you're very in-tune with CM, gerrit and GIT.
We'll be releasing AOSP 4.2.2 as soon as we get the kernel config where we want it to be. Stay tuned. http://www.eaglesblood.com

I think you misunderstood what I said. First of all, I am speaking from *experience*. I have ported AOSP to devices without RELEASED proprietary binaries and I have handled every step in porting; from display, audio, to calling, wifi, bt, etc. Released means the manufacturer provides a nice little package for you. I had to in many cases, figure out which libs from a stock rom were needed. Additionally, you can utilize libs from completely different devices as a temporary patch. I am very comfortable with kernel development and the android framework. If you were too, you would know what I am saying is true. Here is one tip, nearly every board is like another (within the same class; eg. MSM8960, APQ8064) with only slight variations (e.g. modem). Once you understand that, it becomes easier.

I agree with you on some points about CM code, however, you're group has been porting devices that were working or nearly working with base android code. Talk about an easy route. I can see you haven't had to do any hard work yet. Going from 4.1 -> 4.2 on a non google AOSP supported device or a device that has no CM build available for it is a whole different story. How do I know? I've done it. I was the first to build CM for HTC DNA and both CM/AOSP for Oppo Find 5. Next time before you "completely disagree," make sure you know what you're talking about.
Lastly, although I agree with you on some points about CM code, you should give them credit because your stuff is probably based on their stuff more then you lead others to believe; like nearly every other "dev group" out there. And by no means, am I some CM lover (I've had my quarrels with them), but you should give respect and credit to those who make what you do possible.

I never suggested anything about CM, they are top-notch. I said we dont use their base code like "every other dev". Sorry you have had quarrels; and there is nothing "probably based off them" as I just told you our repo is straight AOSP & EB.

What most are not realizing, is that there are two versions of Cyanogen built operating systems. Cyanogen OS is built by Cyanogen Inc. for the device manufacturer and the other is community driven and is open source. These two operating systems may be identical in how they operate once on the device, but how they are developed is different. The question is which one is actually being developed?

If it is a true CyanogenMod rom, that means ZTE would have to release proprietary source codes for open source development. They have not done that as of this writing. So more than likely a Cyanogen operating system will be created for this device totally in house, thereby not allowing for future development by the "open source" community of devs.

From what I'm gathering from the discussions on the ZTE Community forums and the Cyanogenmod dev topic I linked, it seems that ZTE is sending their code to Cyanogen employee Steve Kondik to create an official cyanogenmod github for the A7, not that Cyanogen the company is going to create a CyanogenOS for the device.
Only for USA.

Based on what I have seen and heard, the difference between OS and Mod is nill. They are exactly the same. The difference between the two is how they are developed. One is open source and can be shared by the general public, the other is developed in house for the device manufacturer and proprietary information is kept in house and not shared. The two are quite often just referred to as CyanogenMod, although they are different.

There's a huge difference between CyanogenOS and CyanogenMod behind the scenes though. Like you said, CyanogenOS is in-house, but most importantly it tends to include bloatware, especially now that Cyanogen the company is owned by Microsoft. And since it's closed source, people who want to develop custom ROMs will still have no access to the sources that would speed up development. Plus, if there are bugs or features that people want to implement, they can't, and have to wait for Cyanogen to release them. This also means that things such as security patches will have to wait for official rollout by Cyanogen.
Cyanogenmod, however, is open source, not controlled by Cyanogen the company at all, bug fixes / features can be added and addressed by the community, security patches can be applied to nightlies quickly, etc.

It's been clarified multiple times on the ZTE forum that it will be CyanogenMod, not CyanogenOS. Unless there's some weird, first-time-in-history NDA regarding the HALs / overlay that ZTE provides for the development of CM, they will be open source.
If they did offer open source at least it would alleviate concerns on the Chinese state-sponsored company reputation
Finally, the best hardware of 2016 and all it needs is aosp love... I hope this helps to spur more development or makes it easier for our fantastic developers at XDA.
From what I read from the Employees at ZTE Forums, ZTE currently doesn't want to deal with setting up a place for Devs to access the needed resources for things, so they're basically going to just dump it all on CyanogenMod for them to sort it out. It's easier for the ZTE higher-ups to swallow that way.
Do we have any ETA on this ?
I fear than the OP3 will get more love from the dev, and that the Axon 7 will be forgotten :/

Don't count on anything "open" from ZTE. It really doesn't matter what they may say, the reality this phone doesn't have much more than the day it was released.

The oneplus one still gets more dev support than the Nexus 6p. Oneplus devices get pretty much the best dev support period. That being said, more devs are starting to get the axon 7, but we're never going to be at the oneplus 3 level of support. The oneplus 3 is supported by SultanXDA, flar2, Franco, despair, and dozens more. It had official cm13 support as soon as it was released. It has official support from paranoid Android, elemental x, Franco kernel, PAC rom, dirty unicorns, and pretty much every other rom and kernel you've ever heard of. I love the Axon, but I don't it's ever going to get that kind of support.

One Plus released everything before the phone even hit the market, so there was development for the One Plus 3 from the beginning. The Axon, in my opinion, is a very good device, but ZTE has limited development of this product. It is almost as though they are perfectly happy being an iPhone/Apple wannabe.

Which is never a good thing. Especially when they admit they don't care.
As a Sprint subscriber I'm locked out of the Axon7 until Sprint stop being dickbags about BYOD, which most likely will be never. If that changes, I'll probably buy an A7 if CM actually appears in a timely fashion since Shamu is being dropped by Google very shortly.
...but dumping code on the community and expecting them to make it right is massively annoying at best. It is exactly what Google does with AOSP....The Nougat AOSP is seriously broken and takes a ton of effort to fix enough just to get to compile. The stock AOSP GApps packages are all in varying stages of brokenness as of now. Sure they release the source, but what you get doesn't compile without a ton of forensic work.
Nougat has been on Nexus for over a month (minus Shamu)...and it is not going well.
