Custom ROM development for the global vendor - Xiaomi Mi Mix 3 Questions & Answers

Seems a lot of the GSIs and custom ROMs require the China vendor, not too keen on flashing that on the global version of the device, has anyone tested these ROMs on the global vendor?

We're all waiting on you..... What's your objection to flashing the Chinese vendor image?

I don't think it's objection more curiosity, why would you need to have a Chinese vendor image for a ROM that isn't specifically Chinese, it can be used globally.
To answer your question @ambitiousButRubbish I think the Chinese Developer vendor is needed because the stable Chinese/Global ROM both have bugs in the firmware.

If you wanna stay on stock ROM, just use MiFlash (check the "clean all" option on the bottom) and fastboot ROM for Global version you wanna use. You don't need custom recovery.

Please note MIUI.EU and EU region firmware is difference. MIUI.EU based in global firmware code MI. EU region is EEA with EU firmware code. don't get it wrong.
1. Miui.eu is better for me with less bloatware and still keep miui feature. Use since mi 6x and old poco f1.
2. Indonesian language include in miui.eu
If you want try it UBL and flash global first with MI code firmware last version. Step in Miui.eu rom thread.

Any annoying bugs in xiaomi. EU for poco x3? Did you already tried it?

sure :good:
You can but it's not recommended. Different rom regions use different persist.img (use a hex editor to read it). A different persist.img has different data offsets and it can mess with things like Mi account, compass and different sensors, activation data etc.
Le:fastboot won't flash persist.img even if it's present in the ROM folder. You can flash persist.img from twrp but again, not recommended to flash another version of it.

So, you will try to flash global ROM after getting bootloader unlocked?
My main issue now in 12.0.1 is the dynamic refresh rate or something like that makes gaming experience like a crap as hell even if i stay in fixed 60Hz refresh rate

No problem with all sensor. And Nfc still work remember our device 8GB Ram with NFC maybe not sell on another country except Indonesia. I also still play Pubg with no issue with gyro sensor.

Just saw an update for ID ROM to 12.0.3 from 12.0.2 (https://t.me/s/miui12_official). So, I guess it was a 12.0.2 update too

Is it safe to downgrade to Android 10?

Hi,
i recently upgraded the device to the newest version of MIUI and Android 11. The new Android version seems to have some bugs in performance such as the fact that when playing games the device gets heated rapidly.
I would like to downgrade the firmware by flushing an official ROM.
But is that safe? Anyone had the same experience?
Also i am a bit of newbie so please also give some advice on what i have to do. What i have in mind is flashing a previous build like this one:
HMK305G_V11.1.25.0.QGICNXM_v11-10
or this one:
HMK305G_V12.1.5.0.RGICNXM_v12-11
Custom Roms come also with the new Android version?

No particular problem to downgrade. The bootloader must be unlocked and use miflash (more safe) or twrp to flash the rom.
The roms you indicate are not for the Poco f2 pro and are not original roms.
Do you want to downgrade to android 10 with an original rom or install a xiaomi EU rom?

Thanks for your reply,
I have the Global version installed but i quess EU version will do just fine also. About the files.. hmm i didn't see "poco f2" on the list so i thought it would be the K30 files. Can you indicate to me, the correct rom files to use? I searched xiaomi sites but i found only the latest ver.. i found this repo somewhere in a post here.

Oh i see i selected the 5G as my phone supports 5G and i thought it was a different version. Thanks for the info!
One last thing: You think i should go with the Global or EU version (i live in EU but stock rom was Global), or there is no difference to me?

I think you are confusing: the original(stock) Rom and the EU customs Rom .
The links above are customs rom.
Here you will find the original(stock) Xiaomi EEA or GLOBAL(better) roms .
https://xiaomifirmwareupdater.com/archive/miui/lmi/
EU roms(custom rom) are better than stock.
thank you very much, i will try it!

Hello, I cant find stock rom for MIUI 12 android 10, can you help? I currently am stuck if fastboot and I think flashing stock rom might help
I can recommend Xiaomi.EU custom rom. Was in a similar situation (not happy with stock miui 12.5 poco version). Unlocked bootloader and installed xiaomi.eu. It's much better. No issues so far.

Is there a stock ROM that I can flash to this Chinese phone?
Request OEM/Carrier for it.

Im sorry - I don't understand this answer. This is a (poor) chinese made phone where the vendors have installed their own barstewardized firmware version - complete with nasty parts that are not in the users interests. I'd sooner get some sort of standard firmware on there if i could.

Can i install Global ROM over EEA RoM?

Hi!
I bought a Poco but the vendor sold me one with Europe ROM. I want to know if I can install a Global Stable ROM via MI Flash.
P.d. Can anyone give a official telegram Poco Groups? Tnx
I had the same -- easier path (after unlocking bootloader!) is to use MiFlash to setup the desired stock ROM.
Yeee i think so, cause I feel limited by Miui software.
I gonna try some ROMs. Any recommendations to start?

Pixel Experience for European models

I am quite interested in the custom rom Pixel Experience based on Android 12. Does it also work for European models (AC2003 / AC01BA)?
