CM11 for N900? - Galaxy Note 3 Q&A, Help & Troubleshooting

I was just wondering why CM11 has already been ported to the N9005 but not to the N900? Is it the Exynos sources or simply that no developers have ventured on that yet? In either case, thanks to the incredible developers on either phone that make them even better than they are, and do it all mainly for free

It's both, for the most part. Samdung has a long and sordid history of providing incomplete and/or outdated sources for its Exynos devices in particular, and what impacts things to the greatest degree is probably the missing userspace drivers needed to make the major components (camera, etc.) work properly. They've burned the Open Source dev community so many times and so badly each time that even the best have basically given up and walked away from it.

Most devs don't develop for a device they don't own.. Maybe start a thread in the 7.0 Plus area asking if someone has one to donate and / or raise cash to buy a dev one..
We are pretty lucky with the 10.1 as we have some of the best devs on XDA here..
I know a few devs were tempted by the 7 Plus (an Exynos Tab? Sounds great! At least at first) but then were turned off by the AR6000 driver source code fiasco.
A closed-source binary module that has been identified to be the root of documented stability problems for a device is a developer's nightmare, and a great way to completely kill its desirability for a developer.
I was considering the 7 Plus, but the AR6000 driver mess made me decide to wait for a device that Samsung didn't **** up.
Not like I'd be much benefit - you already have a very good kernel developer and I've given him a whole pile of pointers.

Greatly appreciate your help. I personally own a 10.1 but purchased a 7+ as well for a custom vehicle install.
I understand DEV's don't normally dev on a device they don't have. But it does happen...quite a bit on some devices. Just trying to wrussle up some love is all.
Thank guys
The ability to do blind development is highly dependent on how similar a device is to one the developer owns.
For example, I finally started blind developing I9100 kernels because the difference is incredibly small and you can compile for both I9100 and I777 with just one defconfig change.
The Tab 7 Plus is completely and totally different from anything else out there, and the presence of closed-source modules makes blind development nearly impossible even if there were similar hardware.

Support Xiaomi Mi2/2S please

Hi devs... it is a sincere request from you all...
Here in XDA, we dont have any thread related to Xiaomi's Mi2/2s.
I hope by now people have heard enough about Xiaomi as their latest flagship model is getting shipped soon... Mi3
I request the developers of Omni ROM to support Xiaomi devices, especially Mi2/2S pls just like other CM , AOSP & AOKP ROMs r doing...
Waiting for your reply... Thanks in advance....

Xiaomi are notorious for being flagrant GPL violators, so - highly unlikely.
Just like CM, the real deciding factor for support is, "will a maintainer pick it up?"

Oh come on... please don't punish the users based on company's attitude...
It is a great phone with great UI. just like Nexus 4 it has similar hardware.
All we request here is where ever a new developer wants to build a open sourced ROM, they say not to touch Xiaomi... & everybody wants to build a ROM for Nexus & other phones where they have too many options already...
This is not fair & is not necessary for Nexus & other phone models where they already have too many options available.
I am not saying that you shouldn't , but think in my way also pls.... As you may be aware of there are so many Xiaomi Mi2/2S users alone in Europe & other countries also... but the main problem is lack of good development support. only we should depend on the MIUI developers who keep releasing new build with minimal features based on 4.1.1 version. I mean , we are expecting 4.4 release soon & MIUI is still based on 4.1.1
come on man what the heck is going on... right ?i think always the same like this.... but what to do.. who will listen to our outcry ?
I thought atleast devs here care for our requests.... hence i gave it a go.... I really hope you understand our problem & support this device....
atleast consider from the users aspect pls... Thanks for understanding..... Take care.
I dont have any intention of being rude or arrogant here, i am just expressing my helplessness & pleading the devs for the betterment of android on all Xiaomi devices....
thats all... Thanks once again....

I think you misunderstood. Without the kernel source it is pretty much impossible to support the device regardless of whether a dev wants to or not - we can't change that.

Without kernel source and either platform reference sources, or a good idea of them...you simply can't go making ROMs...
That's why you don't have any. If you really care about custom ROM support, I'm afraid you need to ensure you only buy from GPL compliant suppliers, who use chip sets with good support in open source projects.
Also the prevalence of the device is significant, and I'm yet to see any of those devices in real life...ever... And I'm a phone geek...
If there aren't many out there, the chance of a developer inclined to get it working on any ROM is lower, as they are less likely to even have one.

Yup. If you want a device that has good developer support, do research before buying it. If it's a company that flagrantly violates the GPL on a regular basis - why are you giving them your money?
Basically, I am not spending my volunteer spare time to support a company that is engaging in the practice of managing to steal that which is practically given to them for free.
But seems that Xiaomi will set the kernel source free soon.
At least they said that..

I have an update for you ! Xiaomi releases their source code on 25th October .
Also there is one more hard working developer who without the Xiaomi's sources, has achieved what you are calling as unlikely & next to impossible... only problem for his ROM is camera driver.
He has a thread here in XDA also...
Fine if you all developers have already decided that you only develop or cook ROM for the well known models... it is ur wish. My wish i expressed & likewise you have also done your part.
And to all those who think Xiaomi is not a major player in Mobile industry & who have a false impression that it is just an another Chinese company... should do their research on their different models, their softwares , their track records & demand for their phone models & excellent hardware at best price. I agree they are not bigger than Google, but they are growing at a faster pace. I am not here to boast about that company, but i just shared my 3 months knowledge after buying Xiaomi Mi2S for the first time. Before that i was unaware of this company & had a same opinion like many of the people here have it....
Anyway... if Xiaomi releases for sure on 25th & my favorite developer releases his complete ROM.... pls delete this thread & i don't bother you guys also. It is almost perfect without camera.... thats why i am not using it for daily purpose.... may be you all should take a look at his work once.... AWESOME !
OK guys, dont think that i am trolling here or boasting here or something else.. i am just telling you the facts about my phone & the company which makes it....
Hoping to get a good & positive response from you all...
If Xiaomi makes major changes to their policy of rampant intellectual property theft, maybe things will change.
But in general, for a developer, our most limited resource is time. As a result, it's far better to work with a company that cooperates with the community and treats them with respect (Oppo, Sony, Google's Nexus devices) than one who constantly treats them like ****.
There's also the principle of the thing. I absolutely 100% refuse to work with the devices of any company that commits frequent GPL violations. Even if Xiaomi finally stops violating the GPL, they'll have to work hard for their long-standing track record of extremely poor behavior.
Same reason Samsungs are currently near the very bottom of my priority list, despite them having lots of users. Being lied to shamelessly on a regular basis (such as claiming that N8013 UEALGB was a "leak" and they didn't have to provide kernel source matching that build, despite it being preinstalled on every N8013 sold in the USA) leaves a lasting negative impression.
We should soon see a forum on here. The only reason it wasn't is because they want the source code and we should have that Oct 25 the can't wait.
Ive had my xiaomi mi2 for a little over a month and really like it. Can't wait til we see a forum Here.

And do you think once the kernel is released some dev could enable the LTE in Mi2S?
Seems that the processor Snapdragon 600 has LTE integrated.
But maybe is not that easy...

Its not possible. Its not set up for it. Its a hardware change to get lte. The mi3 is 3g only so the earliest I see lte is mi3s.

A hardware change?? But the snapdragon 600 has not the LTE chip integrated? Samsung S4 has the same processor and has LTE...
I am not an expert, just wondering...
Yes, the S600 does have LTE built-in.
But if the device does not have LTE amplifier on board, you could enable/use LTE, but you'll get really poor network reception.
It's already been done on the Nexus 4, but was not really usable as-is. The lack of amplifier makes it a bad idea. It's only good for the proof-of-concept.
I understand now.. it's a pity... Thank you for the info.
Now the question is, would you buy a phone like Mi2S without LTE,?
now that the 4g is extending more and more, and thinking that the phone should last at least 2 years... I am not sure if i should buy it or not...

Pay close attention to the RFFE block in the first diagram.
The Snapdragon 600 has NO integrated modem. The MDM9xxx does support LTE, IF paired with a WTR1605L - not every device has an L variant, and even if it does, band support requires the right components (PAs, filters) in the RFFE chain.
Yes, seems clear that Xiaomis Mi22s/a will never support LTE.
Waiting for Nexus 5 to choose my next phone...!
Ok guys, is there any point in maintaining this thread ?
when no dev is really interested in working on this one of the best hardware phone ?
I mean other than off topic discussion, nothing really in particular to ROM Dev for Mi2/2S going on in this thread especially.
It is upto the Moderator to decide what best can be done for the fate of this thread & hence Xiaomi Mi2/2S !!!
Thanks a lot for your precious time.
Take care.
OK guys so the Xiaomi kernel is already open sourced. That's a good new.
Will we see a forum here soon??
Hi
I think this might attract the attention of developers especially Entropy, Pulsar & other prominent persons...
waiting for their final word on the development of Omni ROM for Mi2....

[Q] Is there any Dev's going to do work for the G900H version of this phone?

Id like to find out if there are any custom roms for the G900H or if there is anyone that has one that will be customizing the stock rom etc... Kinda sad that there is no one yet Is it because of the CPU???

I am also interested in knowing the answer to this question.. infact the s4 exynos has got the custom roms so will this device follow suit?
Dunno.
Seems people are even less interested this time.
S4 had AndreiLux for custom kernels.

I dont believe that the reason is people not interested. I think its matter of time. First,this is the newest version, and also, the most difficult built with 8 different cores.

Number of cores are completely irrelevant to the difficulty of building a kernel for Exynos. It's all about knowing the platform, the capabilities and what you can and cannot do. Which comes with experience...
It's just a matter that Samsung drove away all developers from Exynos. We used to have really talented devs on this side (Entropy512, Codeworkx, among others), but the lack of support from Samsung and lack of sources for Exynos burned them out.
S4 had AndreiLux, who is an excellent dev with tons of knowledge.
N3 has halaszk, which has done a great job and also brought back features from S4's perseus to the N3.
Don't really expect much for this device. It's not a matter of time, N900 (Note 3 Exynos) doesn't has an AOSP rom and it has been several months now.
I will likely build something when I get time, I frankly want to improve a couple of small things and increase GPU clocks to offset for the lower performance compared to the Adreno 330... but it will take a while, thanks to halaszk's work, I know where to poke.

Will you only build a kernel or a complete rom?? I just so want stock looking custom rom hahahah

Why exynos variant of note4 is given less love compared to snapdragon? (kernel wise)

As the title says, why? For example N910C only gets close to stock kernels (talexop, h-vitamin, suemaxx) while the snapdragon variant gets super customized kernel (emotion)
@Hani K. the developer of Simplicity Kernel (which is the most customized kernel for n910c, but it is only for lollipop) said that he wants to bring Simplicity Kernel to MM
Until now it is still not happening, what happened?
I am not a dev, but i have the snapdragon version, and from what I've read about both phones, I believe it comes down to 2 factors. First, this one is just an assumption, the snapdragon version was more widely sold.
Second, this is the main reason I've read about, that the 64bit exynos chip is harder, more complicated to build for. Cause snapdragon releases its source code and Samsung doesn't provide good info on their chips.
Don't quote me on this, but that's how i understood it, when i looked into this, myself. Some one can correct me if im wrong.
Yes you totally correct, its all about Samsung releasing the source code for their exynos 5433, if developers had access to this, it would be a lot easier to develop for this chipset.
Edit: Just by the way, Exynos 5433 is 32bit based, however the hardware does support 64, due to the missing source code and the array of new devices, it will never be enabled by Samsung or a third party
Well, I have already clarified why it is taking long, but let's start by answering your question:
I personally don't think Exynos Variant is getting more or less than Snapdragon, both were sent to different parts of the world and both are (or were) getting equal attention which was never the case with the older models. However, the device is more than 2 years old now, most of the developers have already upgraded their devices and started development on their new platforms. For me personally, I have been quite busy with life so far, and my close friends knew that since the day I released SimplRom v5, which is why I have created H-Vitamin kernel. Simplicity kernel requires a lot of time and intensive testing, and I'm a one man brigade in my team when it comes to Exynos department due to it's uniqueness, from developing ROMs and Kernels to Sound mods, theming and development tools that I had to create in order to make my work possible. My biggest constraint is/was time and I couldn't afford that luxury, so I went with what most of the people were looking for, "Simple, Fast and Battery friendly", which is H-Vitamin.
Nevertheless, I have posted an update in SimplRom thread a few hours before you make this thread. Since I've got some free time in my daily routine, I'm planning to update some of my projects and when the time is right, I will upgrade Simplicity to the latest version at that time.
I'm guessing it's due to the fact that the majority of firmware developers are US based and the US variant of the Note 4 tends to use the Snapdragon 805.

Custom/AOSP Roms/Kernels?

So I got an S8 the other day as an gift. (G950F) Looking around there seem to be a lack of custom AOSP kernels/roms. Mostly everything seems stock-based.
Coming from previous phones this usually means one of two things. Lack of devs or something hindering development. I.e locked bootloaders.
I know the S8 had issues with Odin due to the new bootloader. Is this still an issue? Is there anything I should know before going neck deep into kernel-sources?
Well, that's because of its processor and platform, usually Snapdragon devices tend to have a lot of development because Qualcomm based platforms are way easier to work with because of it's common source code and architecture, exynos chips seems to be a little bit more messy, they are exclusive of Samsung devices and I think they have a complete integration with Knox and all of that stuff, besides of its architecture and configuration, maybe in the future it will have some AOSP rom, the Galaxy S6 got his first official lineageOS build 2,5 years after its release and it didn't work that good compared to stock, so who knows, you should check the different roms they have around, I'm using RenovateICE on my S8, running alright with some tweaks, you should take a look to S8/S8+ cross device development, there's all you need!
Greetings!
