Possible CM/AOSP development?

Does anybody have any words/rumors about possible CM/AOSP development for the Mi Mix? I love my Mi Mix but I'm really not feeling MIUI at all. Would love to run a CM/AOSP rom on this phone instead. Though being exclusively available in China only really kills the development momentum from the get go. But a man can dream, can't he?

I agree. I want an AOSP ROM android 7.1.

You'll have to be patient and wait it out as the devices is new and overpriced if you want it now.

Sounds like CM is in the works:

Edit:
Looks like a typo by AndroidPolice, it's for the Mi MAX (hydrogen), not our phone (lithium).
It's still early, way too early to throw in the towel....

any updates guys?

Is there no way to contribute (monetarily) to help get AOSP?

no kernel sources released by xiaomi, no aosp. it looks like on my previous mi note pro (chinese only device), which took ages to get sources released.

We could get device tree from similar device and build from there but it's gonna be painful and probably we're looking at a half baked product that wouldn't be usable anyway.
In the meantime, we'll wait for the source to be release.

Should be able to pull the blobs from the phone or the build but without the kernel source I'm not sure how to get started. Has anyone seen the kernel source yet?

Xiaomi is usually too lazy to release Kernel sources for devices which don't sell all that much.
They usually release kernel sources for their flagship mass market devices, like the mi5 and also the mid range devices like the Redmi Note and Max as these are officially sold in a few asian markets outside of China.
The low end and the phones mainly intended for the Chinese market are usually left out. Also considering their phones dont support Google officially in the Chinese market, Android version upgrades aren't a priority for them. Majority of their consumers are content with the MIUI upgrages.

Maybe they learn, said this was a concept phone and aren't making many, plenty out there now, and what we're now making a white one, XDA calls the shots, think they don't check this site.

Well, atleast some super moderator in the MIUI forums have confirmed that the Mix is next in line to receive Nougat. So thats there. At the moment, I'm quite happy with the EU ROM. Its bloat-free and has great battery life. I would love to see CM(LineageOS) at one point though.
As much as I hate Apple devices for their closed eco-system, their UI is very polished. I know MIUI aims to look too much like iOS. Apart from the launcher, I dont have problems with MIUI.
And MIUI is one of the better skins on Android. I'll pick MIUI over most other manufacturer skins like Samsung's Touchwiz or LG's UI.

There's no way a device won't get custom ROMs sooner or later it's a developer's dream.

There definitely is a way. If they don't release the kernel source, that's it for anything but modified stock roms.

http://en.miui.com/forum.php?mod=redirect&goto=findpost&ptid=462506&pid=8662826
thats the only custom rom for the mix thus far and they claim that AOSP will be starting soon

In case ya'll didn't know, someone from EpicROM team on MIUI Official Forum mentioned that AOSP development for Mi MIx will start soon.

Any news?

I would also love to know if anyone has any information as a AOSP rom for this phone would be awesome

Android Q on cactus ?

Hey everyone!
If you have noticed a lot of the older Xiaomi models and some other phones successfully ran Android Q, of course with minor bugs.
So since Redmi will stop providing MIUI updates after MIUI 11, does anyone plan to develop and test newer android version ?
The GSI partition on this phone is just bad, it's not as flexible as other phones.
And there's hardly any chance to port future MIUI versions (tried to port for some other models, didn't boot ).
So do you think maybe it's high time to make up a proper custom ROM for this ?

MTK makes this task stupidly hard to achieve, i don't think we're getting further than treble anytime soon.

That's true, though some MTK devices did achieve full treble support.
I was looking into Xiaomi Qin 2, and I realized it's interface is damn beautiful. Don't know what it runs on but it sure looks nice. Kinda regret buying 6A for almost the same price. I would have gone for the Qin 2 instead. Of course, I don't think Mi is releasing the Qin 2 software or will it ever get ported ?

Why is dev support so bad for this phone?

I have an old mi note 5 pro which I gave to my girlfriend and that phone already has many stable android 10 ROMs, along with havoc and pixel experience, and it didn't even get an official android 10 update.
This phone has official android 10 from xiaomi but there aren't any aosp based ROMs on it. All the major ones have been abandoned and there aren't too many in general anyway. Why is that happening? Is it specifically hard to make ROMs for this phone?

what do you mean by dev support so bad?iff you can question dev like this "quote" (Is it specifically hard to make ROMs for this phone)..why dont you try to make one?dont throw stupid question on this forum..to make a custom rom first you need free time..second need a team to develop 1 rom..third you not getting paid for what you did (yes you can put your donation link in the post but not all user will donate to you..dumn kiddo

Basically stick with MIUI if you want a functional phone with updates for like 2 years. Then you can rely on 3rd party developers. But then again software for your device is not guaranteed. Or better should had bought OnePlus 7/t/pro instead. Xiaomi has a very bad record of updating their device. It's called planned obsolescence. It's better if you learn how to make ROMs if you want to keep your device updated. You can't trust and rely on anyone these days.

Cheaper devices which have lost support tend to get better dev support.
I'd imagine more android 10 roms when the official kernel sources for it are released. If it were never to get Android 10, then devs may see it worthwhile to backport kernels.

Because you haven't out baked any ROMs.

Let's not act like the folks at the MI forums and discuss it rationally instead of lashing out at OP.
My guess is that K20 series is rather new series and has lower salse than extremely successful devices like Note 5 pro. So it has smaller dev base and availability of raw materials yet.

Instead of giving cliche answers like "developers have life too", "why don't you make rom yourself".
Why can't we discuss lack of Android 10 roms for our device? OP asked the right question.
As far as I know, we don't have stable device tree for Q. Xiaomi doesn't release device trees. Abhishek(dev of LineageOS 10) has a working device tree but he wants to make it stable and then release the sources. Once he releases that i think then we will get more Q based custom roms.

Yeah It is not worthy changing to custom rom. Better stay on stock atm

Because it's still a rather new phone, atleast the global one. Custom ROMs in general seem to be dying, probably because official ROMs are getting better and better compared to the times when i had my HTC HD2.

I don't know why everyone is so butthurt about this post, I'm legitimately curious why this is happening. I'm not bashing the devs at all, maybe 10 year old children that can't even comprehend a text should stick to their telegram groups.
Thanks to everyone who posted something actually useful, it seems the official device tree hasn't been released it, hopefully xiaomi will take care of this soon.

At the moment there is a bit of inactivity whilst many devs are waiting for android 10 sources to be released by Xiaomi. I'm guessing most devs don't want to waste time working on fixing Pie ROMs when they know everyone will abandon them once stable 10 ROMs arrive.
Give it a month or so and you'll see done movement again.

Good point, I haven't considered that. This phone is very popular and I was really curious why there are so few custom ROMs, maybe we will get more goodies on android 10.

Really don't need this kind of rage, take it easy. I believe op was just asking. Just a curiosity... Despite your concerns about the words he used to start the talk. I believe it is pretty easy to understand he was not demanding anything from the good guys, the devs, or even trying to complaining about it.
Seems that there's no way to have a civilized conversation about it without getting someone any hassle, saying "why don't you develop? Douchebag".... Not first time I saw this. Weird thing indeed...

Question Change my mind: I bought a Xiaomi Mi 11 but I dislike MIUI

Hi all. I recently bought my first Xiaomi phone taking advantage of a launch offer on Amazon Italy (phone + Xiaomi Mi Smartwatch for 650 euros instead of 830 euros).
I was happy to have a device with a Snapdragon 888 processor, a super camera and an excellent 120 Hz screen but it took a few hours of use to realize that the biggest flaw of this device is the operating system.
I have been using Google or OnePlus phones for years, currently I also have a OnePlus 8 and I must say that the switch from OxygenOS to MIUI was devastating.
Handling background apps and notifications is awful. Often the notifications are not grouped or are identified correctly (those of Telegram are associated with a contact even if they are from another), in the background applications I find the same application several times. Using a "Pixel Experience" theme didn't improve that.
I prefer a device that is more like stock Android than a badly made iPhone.
I think about returning the product to Amazon but I'm here to ask you: why should I keep it? Am I wrong with my approach?
Help me make the right decision. Thank you.

Wellcome to the club
You are on the righ place.
Here you can learn how to customize the hell out of your device. I also use "Nova" launcher and that makes experience so much better for the start. And I apply "viral" custom icon theme pack across all of the apps.
In time developers will start releasing custom roms here that are maybe for your needs and likes. So just be patient and you will fall in love in Xiaomi and the device. No need to return it, it a good device that will just become better in the near future with upcoming updates. There is a 12.5 update coming sometime in April which will have much improvement in many segments.

Weird. After buying why this question?
New trend?
Just buy Pixel or OnePlus.

Ciao compa'
Coming from a Pixel 4XL and yes: devastating.
Using Nova Launcher or installing Xiaomi.eu will solve none of the problems that you are having. Actually Xiaomi.eu, even if based on 12.5, may make experience worts since you'll get Xiaomi apps for browser, dialer, contacts etc. Although Xiaomi.eu does not have the notification problems that you, me and everyone else with a EU Android 11 ROM is having, also on Mi10T phones.
If you contact me via pm I can try to provide some hints to ease the pain...

General I am starting to hate this phone now for one reason!

No custom ROMs. Stupid Xiaomi please release the source and kernel. We are past 4 months and nothing till now. Oneplus 9 pro on the other hand released 5 days before this phone and I see 10+ custom roms in the forum already. Such a great phone with so much user reach and xiaomi doesnt care about software. Only people from China are getting updates every 3 weeks or so (iam not talking about xiaomi.eu rom). Completely neglected Global rom and India rom.
Issue with this company is: It releases 10+ phones in the same price range with different hardware every 6 months and forgets about software completely. If you cant update the software, release the source and kernel for developers atleast!

Agreed

Why u guys talk so much about custom rom?
Im satisfied with eu rom now
Almost nothing need to change

definitely.

They did release kernel sources.

easy easy bro, calm da f*** down.
it's all have a solution, why don't you focus on what actually you using phone for? like play game, multitasking, or take a photo ,etc..
so, let take some experience with another users like me, why you dont try MIUI MIX (MMX Team) it's not bad because it's base on EU ROM.

How do sales compare to s21u or the one plus 9 pro ?
I think the global variant is overpriced tbh.... especially for a Xiaomi phone
Apple can get away with ridiculous prices and even Samsung to some degree but Xiaomi doesn't ring synonymous with prestige flagship grade experience
They're the cheap and cheerful brand...
My friend bought a Poco f3 yesterday and it's a great phone for it's price

I don't hate my phone, I just hate Chinese Firmware. Now I'm waiting for Bootloader and will install Xiaomi.eu

Agreed. Never seen something as horrible as MIUI. Nothing but stupid effects.
If i knew that beforehand, I'd never had bought a xiaomi.
And no, the .eu rom doesn't fix any of its problems.

Not sure why you get personal here.
I always had phones using a clean and functional OS. I knew that the asian customers prefer it more colorful and I expected exactly this. But what Xiaomi delivers with MIUI is a slap for everyone not deepdiving into their software beforehand.
Why is a compass app installed systemwise? Yes you can disable it and even uninstall it via adb. Why can't you hide apps in the drawer? Lets say I dislike their contacts app and want to use another one, I then have to have both on the drawer without the ability to hide theirs (yes, you can hide some non-system apps behind the app-lock). Why does Onehanded Mode not work with gestures? Why do they force you to wait for 7 days before you can unlock the bootloader and why do you need a sim-card in the phone for this and give them your number?
The "cleaner" app does nothing but spying, even worse that such software doesn't even (ever) work on Linux based OS. Not mentioning the "security" app that is another piece of scam software they integrated some system relevant services into while on the other hand, blocking essential android services and thus create a lot of issues non-existant on other devices.
If you ask me, MIUI as a whole is nothing but a scam. Google sniffing apps can at least be disabled, no chance for the Xiaomi ones.

Here's the reality, there really isn't that much demand for custom roms. However, there are two that I know of, Xiaomi.eu and MIUI MIX. ONE OS may also have one, but I am not sure on that though. And even though you do need kernel info, you can't expect them to release the proprietary info regarding the rear screen and other features. So even if a rom could be made, there are many things that the developers would not be able to make work. For example, the Mi 10 Pro went the greater part of a year before one started to see custom roms for it. Custom roms, back in the day, were updated regularly and in some cases nightly. Now the original rom and security update can be several months old and it might also be several months before a new version appears. In my opinion, it's really not worth it nowadays and the most of the devs seem to have found that out too.
As for their marketing, I too feel they release to many phones, but apparently it's working as they have become number one in the world.
