[News] [Kernel Sources] Update on releasing kernel sources for Mi phones in India
SEE HERE
Mi fans,
Hugo and I wanted to provide an update on releasing Mi kernel sources, as this is a question we get very often. I can personally guarantee that we will release the Mi 3 kernel source within Q1 2015, and will also be releasing the Redmi 1S kernel source in December 2014.
The reason we have not shared kernel sources yet is actually quite simple. Hugo explained this at the press conference in India last week. The kernel source code for these devices contains a significant amount of source code that will be used in two upcoming models. If we release the kernel source in its current state, we will be revealing more than we would like to about future devices. We will change this going forward, but right now it is a constraint we have to live with. We hope you can understand this position, and we're very sorry for the frustration we may have caused!
Thanks for your support, and please keep the feedback coming. We are always looking to improve, and we promise we will do better in the future!
Cheers,
Donovan & Hugo

Plz sign the petition if you guys want that the kernel sources must be released.

If kernel sources aren't released yet, how is it possible that there are some custom ROMs already out there?

Dude without kernel sources the devs cannot build or modify custom kernels. Else it has nothing to do with roms as the rom sources are ported from lineage or aosp sources and modified accordingly. without kernel sources there isn't much room for kernel optimisation and modification for better performance or battery as the devs have to use the stock kernel of the device.

So those custom ROMs are using the stock kernel, copied from the original MIUI ROMs?

Yeah with few optimizations and changes.

Xiaomi / every android manufacturer has to release the kernel sources anyway, right? Is there an ETA, or how long does it usually take for a xiaomi device for the sources being released? I am considering buying this phone.
2nd question: rooting or unlocking bootloader goes with the manufacturer's page right? I checked it out and it was in chinese, me as an english user, will i manage to get the phone unlocked?
Petition is signed anyway. I also contacted the global service through mail asking about the REDMI4X32_GLB_BLK kernel source release. Will keep you updated if I get a response
Edit: I just ordered a moto g5 but will keep u updated if I should get any info from xiaomi support.
Edit2: Reply from the Xiaomi team:
Greetings from Xiaomi!
Thank you for writing us. I will be glad to assist you.
I understand that you wish to know regarding the release of Kernel source. I would like to inform you that as of now we do not have any such update and provisions regarding the launch of Kernel source for the Redmi 4X, so we would not be able to guide you regarding the same and the reason behind its non-release. You may refer our Official Website http://www.mi.com/en/ and Facebook page https://www.facebook.com/xiaomiglobal for more information.
Should you have any further queries, feel free to write back to us. We'll be glad to assist you further.
Thank you for being a valued customer. Have a great day ahead!

Still no response?

Will we be getting Official LineageOS ROM?

Since we got our own section now, will we be getting officially supported LineageOS ROM?
Are there any chances or we are on our own?

Without kernel sources, I doubt it.

AFAIK, Xiaomi hasn't released kernel sources for lots of new devices which is a violation of GPL licence. I don't know why they are not releasing kernel for a device that is released last year. Damn!

Roms for Xiaomi RN9?

I've seen there are many custom roms for RN9s and RN9 Pro. Why does our RN9 doesn't have? Will there be roms for us someday? Just bought the phone and thought there were roms I can install

I think its up to xiaomi, because ROM's devolopers usually waits for the official kernel source to be uploaded by the manufacturer. This reason might explain why there are plenty of Redmi Note 9 Pro/S ROMs (already with kernel source uploaded) but not even a fully functional TWRP recovery for Redmi Note 9. We might need to wait for xiaomi official kernel source for RN9 to start seeing functional stable ROMS running out.

Where does xiaomi release the official kernel source code (which website?)

Here, at official Xiaomi Github channel:
https://github.com/MiCode/Xiaomi_Kernel_OpenSource

Maybe we should wait, RN9 still a new device. And there just an Unofficial TWRP, maybe after the official TWRP got released we will got some custom ROM.

I suggest you to keep on stock rom firmware only.
Root it with magisk. Flash it with twrp.
And everything is fine.

Question Why are there so few official custom roms on this highly sold model?

I don't understand

Have you looked at the Telegram group? A lot of development seems to bypass xda these days. That slightly worries me as the ROMs are all unofficial and I'm always worried what might get added - surprising we don't get ROM based malware more often. At least here reputation is long term so that seems less of a risk.

Yes, I'm up to date on telegram, that's why I ask, they are all unofficial custom roms or ports and I don't understand why no dev team works on official roms

I wish I knew - staying on MIUI until there's something official, ideally crDroid, Lineage or similar long term projects.

To avoid any errors of judgement:
Official ROM maintainers are not supposed to make changes to the source. So, they are not likely to fix any bug which is related to the source. Meanwhile, unofficial ROM maintainers are not having any restrictions. They are free to make any changes to the source to suit their needs. So, the unofficial maintainers often fix source-related bugs before the official one.

That's how I understand it, and having that level of code review in the official builds is what almost guarantees you can trust a ROM with your banking etc. I haven't actually heard of any unofficial ROM being naughty, but there's nothing to stop it.

For having used with several devices, several official or unofficial roms over several years, I have never had a problem with banking apps (for those who support them, of course).
Note that when there are no more brand updates, the developers are obliged to modify the source to continue to develop the rom.
XDA is a trustworthy source, for others I don't know.

And following that explanation...why are there other low-priced xiaomi models and also old models that have many official roms here on xda? I am very concerned that we have many unofficial aosp roms on telegram and here on xda absolutely none. Why do the devs of this model never publish on xda and other xiaomi models do? That doesn't give me confidence and I still don't understand

Surely a question of rules and money.

Xiaomi 11T Pro codename vili Kernel is still stuck on Android 11 meanwhile we are expecting Android 13 soon.
Many devices are missing there and also lack of kernel update.
