Xiaomi Mi 9 ROM with support for LHDC? - Xiaomi Mi 9 Questions & Answers

Hello, I'm looking for a custom ROM for my MI9 that has support for my Air2s earphones that have support for the LHDC audio codec. I have tried the xiaomi.eu ROM which works great with them but the battery life with the rom is terrible. Stock MIUI ROM is supposed to support them but it doesn't work for me and neither does the popup that displays the earphones battery life.
I'm currently on Syberia ROM which doesn't have support for LHDC as I found out after installing it. It's supposed to be included in every Android 10 phone but needs implementing by the developer. I was also wondering if a Magisk Module would be able to do this?
Thanks for any help.

Global MIUI 12.0.2.0 LHDC v3 works with air2s!

Hey, if you want to use LHDC with Global/EEA version, update to 12.0.2.0, then air2s are working with MI9 LHDC v3.
If you have no OTA update in europe, switch region to "switzerland" and you will get it.

Mi9 noob - Unlocked, now which ROM to use?

Hi all,
First up, I have been running 3rd party ROMs on my old Sony Z2 for years (TWRP with Cyanogen then LineageOS).
So i'm semi-experienced with running other ROMs.
I have a Mi 9 global currently running the latest stable official Global MIUI.
The bloat and calling-home by the Xiaomi stock apps is ridiculous, so want off ASAP.
Ideally I'm after a very lightweight, stripped down version of Android with OpenGApps Pico (or equiv).
All hardware working would be a bonus (losing IR and NFC isnt a deal-breaker. Need BT working though).
So what would you guys recommend I run?
Thanks in advance
xiaomi.eu
I bought my mi 9 before 1 week and yesterday I unlocked the bootloader and installed Xiaomi eu , I'm very happy with it and i got 9h of Screen Time on.
I'm in same position as the OP. Waiting 6 more days before I can unlock and also keeping a close eye on the stability of Pixel Experience rom. Currently using it on a Samsung S7 so that will be my first choice.
Xiaomi.eu or Revolution OS are both great Miui roms.
Pixel Experience isn't stable enough for you I guess. But in future it will.
hello friends I have a problem when I unlock my 9 install the twrp that says on the page xiaomi.eu and I liked the rom and wanting to update to 9.6.13 try to enter the twrp and I can not appear the black screen and restart to the rom that I currently have from xiaomi.eu 9.6.5 someone can help me.

I replied to your other post.
Revolution OS > xiaomi.eu (if you don't like constant Softwareupdates - in case you debloat one of those & install magisk mods).
I don't say xiaomi.eu is bad, but I'd prefere to not update my smartphone unnecessarily ("never thouch a running system").

Question Revert back to global MIUI

I have flashed the Xiaomi eu rom on my RN 10, now I want to go back to the global version. How to do it?
Edit:
Link for stock rom

Just out of interest, why do you want to switch back to the global rom?

How was stability for you? Was it as smooth as the stock rom? Also, did you check if the call recording feature works in Xiaomi.eu from?

You can, it's the same ROM, at least for xiaomi.eu
The first thing I do when I buy a xiaomi / redmi / poco is to change my rom to xiaomi.eu. I prefer to have the mi phone and mi messages aplication and there are options that the Global rom does not have, such as super wallpapers for example.
Has ther been any issue about going back to Official Global such as Anti-Roll-Back etc.?
Didn't flash for some time and asking myself if it's still a problem...

Once you went back to the official, did you notice performance improvement? I'm on xiaomi.eu and found a couple of issues with apps and also some apps are behaving very slow. I don't remember that in the week or so that I had the stock Rom....
I assume you are already unlock bootloader. Just flash it with miflashtool (found on official website). I already tested. From Global to EU and back to Global Indonesian. #DWYOR
The regular Global is suck, dialer, message and contact using google product.

Question Mi 11 ultra - xiaomi.eu or global rom?

Hi, I have a 11 ultra Chinese version, after waiting 7 days to unlock and all of bugging twrp installation, I finished to put stable xiaomi.eu Rom on it. But somehow I find that eu rom now have a lot of small bugs.
Don't know that should keep it or go to global rom?
Xiaomi EU is overstimated, it may be good for west people who wants a debloated and translated china rom with Google services,but Global Rom is much better and also is faster

i will give eu a last try after an fresh installation ...
I didn't try myself the China ROM but I read it is more performing than the Xiaomi EU as well as Global and EEA stock ROMs
When I got my Mi 11 Ultra I started the process to unlock it right away since it uses the Chinese rom. However, by the time it was ready to be unlocked I decided it wasn't worth the hassle. The Chinese rom with the Google playstore installed does everything I need it to do. I don't really see any reason to change to the global or eu rom so far.

The Global Indian (IN) ROM is smaller in size as compared to the Global (IM) ROM and they are pretty much identical.
The IN ROM though has the Red Dot notification light displayed in the Rear Display when there is any notification.

Edit:
So this option is available in the Global MI Rom but you may also have to enable another setting which might not be 'enabled' by default.
Notification Access > Rear Display > Allow Notification Access
A regular notification option is available but it is pretty limited. I think it is for Spotify integration (music control) and Answering the Phone.

Quite content with the Global MI ROM
By IN ROM you mean Indian? Because the standard Global is easily rootable
Chinese rom is the best one. 120Hz everywhere.
Latest patches latest updates but no Ok google and no android auto. (At least in old versions of software)
I didn’t like global rom because many apps including YouTube is not working at 120hz.
Obviously China ROM is more updated and more refined,

1. MiUi dialler & Contacts - Didn't like it. Prefer Google
2. MiUi power down screen - Didn't like it. Still prefer Global ROM screen.
3. Google Assistant didn't work from lockscreen. It has to be running in the background for it to work from lockscreen (fingerprint protected)
The CN ROM does have some extra neat animations (like Battery Charging animations) which I would look to have. But I can do without it.
In Global MI ROM, Google Assistant is a system app I guess. So it's in the background by default? It works well from lockscreen.
Red dot notification in rear display works on Global MI ROM but doesn't work on the CN ROM. The Xiaomi.eu's (CN) ROM.

I would love to test video. I don't quite know how to check the Hz. Honestly I haven't tested my phone yet.
How do you check how many Hz when watching YouTube?

IN as in Indian yes
IN ROM latest fastboot ROM is v12.0.2.0 and then OTA update to v12.5.2.0.
I didn't know if I would lose root so I thought Global MI ROM is better. Lot more fastboot ROM releases and perhaps some added features looking at the version number and size of the MI fastboot Rom.

Xiaomi.eu all day. Faster updates, more tweaks and features over both stock CN and global. I immediately went Xiaomi.eu and haven't looked back.

ok ok
after two days of use, a syatem debloating, a settings optimizations, i think miui13 i better than 12.5. dark mode bug for apps is solved many functions of miui13 are missing, but i think will be implemented. updating to last systemui plugin, you can enable latest control center. so in my opinion is a good initial release.
IMPORTANT: IS NOT POSSIBLE UPDATE VIA MIFLASH. FASTBOOT VERSION IS NOT YET UPLOADED. ONLY WAY IS FROM GLOBAL VIA OTA OR TWRP. USER WITH PHONE BRICKED SURE HAVE FLASHED A WRONG VERSION. USE BRAIN BEFORE FLASH A FASTBOOT FIRMWARE IS IMPORTANT

uh, some of the people in my country downloaded the update file in MIUI updater app found in playstore, they downloaded Poco M3 Pro miui 13 but they experienced soft brick, some updated using the updater in settings (settings - about phone - update) they still got softbrick. I wonder if its safe to update because no matter what "they" use they still get soft brick

miui 13 updater is not official. so i'm sure they have downloaded a wrong firmware. miui 13 global is not yet official, is only for pilot users like me

I also received both MIUI 13.0.1.0 and 13.0.2.0 OTA update notification for my Poco M3 Pro 5G even though I am not part of the Mi Pilot tester programme.
Have you updated to this release?
For this OTA update, did Xiaomi upgrade the Linux Kernel, Vendor and Modem firmware?
Currently, I chose to remain with Android 11 (MIUI 12.5.5.0) as most phone with Mediatek Dimensity 700 chipset haven't release the Android 12.
i have updated, but seems equal to first rel. i dont understand the sense of this update
edit: 13.0.2.0 is the stable ver. so all user could recive OTA from 12.5.5
tip: install manually latest systemui plugin for have new control center
edit2: before 48 hours, i have noticed 2 crashes of systemui when i recived a call with screen off. phone ring but google phone mask missed, no notification, unable to answer the phone call. maybe depends from system ui plugin update but i'm not sure
edit3: i have a new clean installation of miui 13. seems better than update from 12.5.5
I did a static analysis on the MIUI 13 13.0.2.0 Android 12 OTA update and I spotted that the Modem firmware is downgraded when comparing to MIUI 12 12.5.5.0 Android 11.
For Android 11 MIUI 12.5.5.0, the modem firmware version is MOLY.NR15.R3.MP.V4.3.P70
While for Android 12 MIUI 13.0.2.0, the modem firmware version is MOLY.NR15.R3.MP.V4.3.P68
I'm curious why MIUI 13.0.2.0 downgraded the modem firmware release back to the same version used for MIUI 12.5.4.0

it depends what you exprct from. miui have the best ram management i ever tried. if you want to trick, you can with root and franko kernel app. but i suppose you are expert, or keep default setting. my free ram is 2,3 from 1,2 average without gaming. in ny opinion is very very good. render graph is under green line. no lags. how you say terrible??? kernel stock is setted for the use of most user. i suppose u have a particular apps that need a custom ram management. for use more ram disable or reduce zram. for free up more ram disable bloatware.but change scheduler is the best solution for you. by default is cfg. schedutils is the best. but root needed for change

Question What's the best version of stock MIUI in terms of battery life and stability

Hello guys
I would like to know just in case I went back to MIUI which version I should flash , I was happy with 13.0.10 overall, but there were two annoying problems the 10 seconds warning every time an app need accessibility permission and the MIUI battery optimization which interrupted the apps and cannot be disabled in version 13
right now I am thinking to back to either MIUI 12.5.1.0 or 12.0.x what you guys suggest ? also if there is any kernel that can improve stock MIUI please let me know
Thanks in advance

For me, latest 13.0.16 EEA has been the best so far. But people have been saying latest Indonesian version is the best for them. Try it out, also for custom kernels, I don't recommend changing as that would ruin deep sleep and fast charging.

I think any custom should be compatible with yours. Most incompatibility comes from 64mp one. Maybe some devs forgot to disable/remove NFC functionality for sweetin, in that case just don't touch that module.
Xiaomi.EU should be compatible as well
