Look at the link below... Personally waiting for update by OP, there must be a reason he's not updating builds to this thread. :)
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Likesoft:
I've already recognized the link from replies.

But what I wonder is where and how that link has come from.

The origin of the link! That is what I wanna know. :)

By the way what is the exact meaning of 'OP'?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] NaassomDourado:
builds are not posted here because they are testing builds. There are also 3 other roms currently being made, in closed tests :o

[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] mi9lite:
Nice! This means that this phone is getting some more support which is amazing. Because this device is really good and has all the features anyone wants for an amazing price!

Thanks for the information!

But for now, this version seems to work well for me. I'm using Lightning Browser from F-Droid though, not google chrome BS, so no freezes either :)

BTW: what camera are you guys using? I'm using ANXcamera and HyperCam, both are good but not flawless.

hi,

i'm a new owner of mi cc9

few questions please :

safetynet

google pay

netflix full hd

fm radio

overall stability

thanx
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] :
Safetynet have no problem

Idk for gpay

Their no Netflix full hd support (need global Android 10 miui 11 update for add this)

No fm radio support

And it's generally stable
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Animux:
Google Pay is working fine. (With magisk gpay fix module.)
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] propofol1:
Hi all, I found some problems after the installation of this ROM:

- occasionally the phone doesn't wake up from lock: the screen doesn't turn on even if the telephone is switched on (I'm shure that it's switched on because I can activate the flash with a long pressione of the Power button)

- the reproduction of vocal messages (WhatsApp) scratches (only with vocal messages)

- the notification led doesn't work

- the function "divide screen" doesn't function

Has someone the same problems?

Thank you
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Hellsingoff:
Not even close. Until the problem with GMU is fixed, all ROMs will freeze and restart, it simply cannot be called stability. coderzs has already fixed the problem with kgsl, but not fixed gmu error yet. I can only use this ROM on my mi9lite because now I’m using my old smartphone, I just can’t fool a person and say that the ROM is stable enough for daily use.

Yep. For now GMU is broken and sometimes device is freezing. Until it is fixed there is no reason to fix others problems:

IR not working

LED not working

Troubles with audio

Troubles with two sim

Chrome 75+ didn't work (generally los bug, as i know)

And more.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] kalebwinefield:
What is GMU and kgsl?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Hellsingoff:

[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] tomgar:
Does this ROM have many bugs?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] P.Rabbit:
The last build that is not published here, reboots from nothing and blocks several times.

It is not stable enough for day-to-day life. The problem is with Android Q sources, which Xiaomi has not yet made available, as developers and testers are working hard and ugly. Hopefully better days for AOSP roms for our beloved Pyxis.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] tomgar:
Then Lineage 16 is more stable?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Tomek0000:
LOS16 by gringo80 is not more stable. It is stable and advanced. I think the current version can be final version .

Hi guys , I have been running lineage-17.1-20200213-UNOFFICIAL-pyxis-mode.zip (added on 2-19-20) since yesterday and so far not even one single hiccup.

Seems faster, more fluid, I have been using the whole day with no freezing nor slowdowns.

I run Magisk, Adaway with a hosts file +1.8M entries and it is butter smooth.

The only difference on installation I noticed ( previously was using 2020120) I had to wipe the whole thing to make it work , not sure if I did something stupid...

Anyway so far so good.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] ezraravin:
That sounds like good news. I would like more confirmations and the ability to install it without wiping..

Is FOD working? After reboot, too?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] JimmyBondi:
I tried it yesterday with a clean installation, but my phone freezes more than 10 times in less than two hours.

Idk what's different in my case.

I'm back on 20200120 now.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Hellsingoff:
He talked about a version with a modified kernel, where no one was able to catch the hang so far at all. This can be seen by the name of the file, the postscript at the end. coderzs will build a new version with this change as soon as he has free time, I think.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Subaru99:
Which version is the most stable-ish right now?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] L_e_x_t_e_r:

[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] cardonarico:

[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] L_e_x_t_e_r:
which version (build date) you are using?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] qmtd:
Could you or someone else who's managed to install it, explain in a little more detail how you managed to install it, because I get stuck in a boot loop & get sent back to TWRP... I'm a little bit of a newbie.

Thanks. :)
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] cardonarico:
FOD personal experience on this ROM + IR blaster

Look, based on my experience every single release of this ROM worked concerned FOD.

Some versions was kind of slow , not much accurate and so on .

The version I am testing now and it seems the FOD is working flawlessly is lineage-17.1-20200213-UNOFFICIAL-pyxis-mode.zip (added on 2-19-20).

Also I am still using the firmware recommended by the developer (9.12.26).

Finally I was able to test the IR blaster a few minutes ago and it seems fine.

LOL, What you just described is exactly what happened to me.

Here is the cure (so far worked for me):

on TWRP:

-wipe

-fomat data (confirm typing yes)

-press back

-advanced wipe

-check dalvik/art cache

Internal Storage

swipe

reboot
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] ngorom:

[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] sambahb:
Are there installation instructions for those builds? Is it wise to flash them over the existing installation of the same rom or should I clean something before.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] ezraravin:
If I understand correctly these are closed test builds. They are not safe to install over existing installations. Every attempt so far resulted in a boot loop. Some users reported that if you wipe, you get a clean build. In my opinion, more confirmations are needed and the best one should do right now is use the 01.20 build and wait for the next stable version.
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] L_e_x_t_e_r:

Chrome & Spotify still crashing for me on lineage-17.1-20200213-UNOFFICIAL-pyxis-mode.zip, new build came out few hours ago so will test on that later...

Chrome still a bit buggy, wouldn't recommend using it atm... crashes frequently but a lot less... But anyone who uses Spotify should be happy to know it hasn't crashed once for me on the latest build... (lineage-17.1-20200220-UNOFFICIAL-pyxis) huge progress... :D Experiencing a few UI crashes where the whole green goes white, but when I press the volume button it seems to fix it.

Huge thanks to [MENTION=3297592]coderzs[/MENTION] for his hard work!!

Working fine for me... Read instructions below

The below is not needed for the new build lineage-17.1-20200220-UNOFFICIAL-pyxis

Follow OP's Instructions and all will be well!

After you've followed original instructions, follow these instructions below to make it possible to boot into the test builds...

Without following the instructions below you'll get stuck in a bootloop.

Working on lineage-17.1-20200213-UNOFFICIAL-pyxis-mode.zip, will test on lineage-17.1-20200220-UNOFFICIAL-pyxis.zip which came out a few hours ago later today.

Hope this helps...
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] qmtd:
----

Oh wow... Looks like new build not having this issue anymore, Ignore everything I said above, follow OP's instructions with latest build lineage-17.1-20200220-UNOFFICIAL-pyxis

No more bootloop & the need for this fix, will continue to test :)

Boot to recovery

Do FACTORY RESET

Flash the latest build

Boot to recovery again

Flash gapps

this steps are clear so far but how and when do i have to install the 9.12.26 firmware ? through twrp or with miflash ? and when before flashing the newest los build or afterwards ?

and is this the right file - Firmware-pyxis-9.12.26-ch-dev_10.0.zip ?

hope someone can push me in the right direction ;) thx

there is a link with the name of 21.02 however I installed the build of 20.02 which continues to block, in this case, blocked while surfing the internet with the VIA browser.

I formatted the data, made all the wipes and continues to block. there is one or two boot.img files but I don't know which build they are for.

The developer should update the post with the necessary information, thus avoiding confusion of posts.

What I did is wipe all, flash 9.12.26 (~75mb)

Then follow the instructions listed by OP... :cowboy:

Files for 9.12.26 are below

I also don't see anything about a 21/02 build in the Mega link... 20/02 working good for me, with a few minor UI bug mainly when rebooting (doesn't occur on regular use) + chrome bug (currently using Opera with no problems).

It is a lot more usable than 20/01, infact i'm currently using it as my daily driver :fingers-crossed:

Hi there,

Just to inform I went from lineage-17.1-20200213-UNOFFICIAL-pyxis-mode.zip

to lineage-17.1-20200224-UNOFFICIAL-pyxis.zip (latest version - February security patches ) .

So far so good no freezing at all , FoD fine , etc , etc

Also I didn't factory reset the phone , it was simple and smooth.

Hi, thanks form the update, very nice.

I found:

- no freeze / auto reboot (even with notification active in lock screen)

- very nice panoramic menù. Unfortunatelly there is not the possibility to split the screen in gesture navigation mode (how we can active It without using navigation buttons?)

- notification led doesn't work

- in general i have the sensation that Is slowlier than the January version (particularly concerning apps functioning e.g. macrodroid, launchers and other)

Is it possible to use FOTA updates after flashing your rom?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] loc182:
Hello friends, from now on a huge thanks to [MENTION=2674483]Coderz[/MENTION] for this effort and great work in this rom for our terminal, very fluid, smooth, with a battery optimization and very remarkable performance. For those who are going to flash and want to know what rom it was like (it was on xiaomi.eu 20.1.21 and did not update firmware 9.12.26, I made the flash directly from xiaomi.eu to LOS 17)

The steps I followed

* restart in recovey mode

* reset the cell phone to factory settings

* flash LOS 17 2020/02/26

* restart in recovery mode

* flash bitgapps

* clean dalvik art cache and cache

* and reboot system and ready to configure

I have not had any freezing, I did not turn off my cell phone, I had no problems with chrome or fingerprint or anything, everything works amazing (well I just can not download netflix, I do not allow it) but it is not a big deal again thanks [MENTION=2674483]Coderz[/MENTION]
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] Subaru99:
Still, bootloops, Jesus... tried 20.1.21 firmware and latest LOS (17.1 - 20200226), also flashed vboimage right afterward (I think it's vbo or something like that) and you are right! bootlops again... I'm not gonna quit so if anyone has any ideas? Thanks in advance!

You're probably doing something wrong. Which steps are you doing?
[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] mi9lite:
The way I installed the update without any problems, coming from the 20200120 build:

-Reboot to recovery

-Make full backup in case anything goes wrong

-Flash newest firmware (20.1.21: https://xiaomifirmwareupdater.com/firmware/pyxis/ )

-Reboot to recovery

-Wipe system+cache+dalvik

-Flash new build+gapps(I use Nik gapps)+Magisk

-Reboot to recovery again

-Reboot to system

This Build is very good, only "problem" I have is that the LOS dialer and SMS App don't have dark mode. Is this just me or can anyone confirm?

Thanks [MENTION=3297592]coderzs[/MENTION] for your work! Where can we find donate link? I don't see it.

[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] JimmyBondi:
Some Users are reporting, that their Phone is still freezing or crashing.

I had a similar problem at the beginning, so I started with installing MIUI again and here I will show you, how I solved it in my way.

You need :

MIUI ROM_20.1.16

TWRP v 3.3.1-7 by brigudav wich includes a batch-script for flashing

And latest LOS release and Gapps from OP

- boot to recovery

- format data -> yes

- reboot to recovery

- wipe data

- install MIUI Rom

- boot System to MIUI

- skip everything during initial setup

- boot to fastboot

- install twrp with the included batch-script

- boot to recovery

- format data -> yes

- reboot to recovery

- wipe system, data & cache

- install latest LOS build

- reboot to recovery

- install gapps

- wipe cache/dalvik

- reboot to system

- make your initial setup

optional :

- boot to recovery

- install magisk (you find it in twrp under the advanced tab)

- boot to system

- in Magisk Manager install SafetyPatch (for passing SafetyNet)

Hope, that it will solve some problems and help some other users too

edit: changed source for twrp, because it installs vbmeta automatically

[Xiaomi Mi CC9 / Mi 9 Lite ROMs, Kernels, Recoverie] shinzo_ningen:
I had the same bootloop problem and was really frustrating. What fixed it for me was applying the vbmeta patch on brigudav twrp after doing practically the same as you. What it does? No Idea, i catched it in some other thread detailing about a/b structure in Android 10. Literally grasping at straws but this fixed my bootloop on this Rom.

I experienced bootloop after the newest update, too, and this was the solution for me: https://unofficialtwrp.com/twrp-3-3-1-root-xiaomi-mi9-lite/

Great thanks to shinzo_ningen for pointing out that a vbmeta patch may help! That way I found the unofficial TWRP. (Be aware that, after installing unofficial TWRP, you have to change the language from Chinese to English first. Just select "language" and "english", they will be the only words shown on the display you’ll understand – unless you can read Chinese, of course – so it won’t be difficult. Be also aware during your selection in the advanced wiping menu, the selection order will be different in unofficial TWRP, so be careful there.)

1. Is there any way I can check my current version of linageOS? (Edit: I’m stupid. Go to 'About the Phone' and tap on 'Android Version'. There it is: '17.1-2020026-UNOFFICIAL-pyxis'.)

2. 'Dark mode' for the dialer and contacts is still not working. I changed to 'dark mode' in 'Settings' -> 'Display'. After opening the dialer or contacts the three-dots-menu won’t show an option for 'dark mode'. Anybody experiencing the same?

Thanks in advance!
