WOW!

LOS 20191221 runs like a charm. Of course, some minor bugs still in but not hindering from daily usage. At least not based in my short experience since 20191219 build.

Cheers

Hello,

I assume this ROM uses newly available kernel sources? https://github.com/MiCode/Xiaomi_Kernel_OpenSource/tree/cepheus-q-oss

Does it fix any issues that were present in P? Like fingerprint with screen off? https://github.com/MiCode/Xiaomi_Kernel_OpenSource/issues/1164
What prevents this ROM from becoming official?

Stop mentioning fingerprint with screen off. That doesn't exist. Screen cannot possibly be off if the fingerprint icon is shown. Xiaomi has a special AOD mode for that. We don't. And we don't intend to implement it.

Also, 17.0 is not officially released yet, so an official release for our device is not possible yet.
Besides that, NFC and sepolicy need to be fixed.

I'm trying this the rom but I have a problem when i try to open the multitasking, trebuchet crash and is impossible to close the open apps; but except this problem the rom works flawless.

First of all, thank you for your effort to port this ROM to the Mi9. Lots of things are already working good in this version but I'm facing problems with the sound. There is no sound from spotify, no notification sounds and voice massages can not be played in WhatsApp.
Is it just me, or does somebody else have this problem too?

Btw. I'm coming from syberia project and installed the ROM the way described in the first post.

Haven't experienced anything like this, sound works properly here.

Hi, I am thinking of changing to LOS. Does gestures work with Nova Launcher?

Hi there,
I have currently installed the Miui Global 11.0.3.
Do I also have to flash the vendor or firmware?

 

[Cozzmy13]

Everyone should flash and boot into MIUI 11.0.6.0 before trying this ROM.

 

[chrisuwd]

this - MIUI 11.0.6.0.QFAEUXM?
