Because according to my online seller it does.
Question roughly translates to: Which ROM? If I encounter any issues can you help to claim the warranty (to China)?
He answered "Global ROM. Yes I can help"
But the question now is: does a global official stable ROM even exist for this phone? Isn't it China-only?
I bought the MI 5s Plus 64 GB in China a few days ago. I can confirm you there is no Global ROM yet. However, the stock Chinese ROM has English as language. You can also install Google Play Store and uninstall any bloatware default apps.
There is an Unofficial EU ROM if you wish to try.

I got the Mi5s (not plus) last week and it shipped with miui 8 global rom including pretty much any language not just english and chinese!
Please note that the MIUI rom could be manipulated by the guy who installed it. Currently there is no official global rom from Xiaomi for the 5s. All the currently sold ones with Global ROM are unpacked by the seller and reinstalled with some MIUI rom, which could be manipulated. Also OTA updates won't work with those mobiles
I'm also waiting for an official global rom, it's just not sure yet if there will be one.
I bought this phone with chinese rom and I was going to flash global rom as soon as it is released. but I'm not planning to change the rom anymore. I have debloated it myself and I'm happy with it at the moment.
I have to admit, I'm pretty disappointed. I honestly didn't realize I wouldn't be getting official MIUI.
Is there any particular way for me to see if there is any harmful backdoor software installed? So far this "global ROM (8.6.10.0)" seems solid enough, all functions seem to work except that when I go into the updater and try to choose an install package it tells me to install file explorer first....
I'm downloading the stable, official Chinese ROM right now... Not sure if I'll install it or not though...

I got such a vendor "global" rom, tried to flash with official chinese zip, did not work -> verification problem.
unlocked bootloader, flashed twrp and xiaomi eu rom based on official chinesese developer rom..
Will wait for global rom as chinese rom is too much bloated..
If they launch it in india(hope so), global rom will exist, otherwise xiaomi eu forever...

So, you had success in unlocking BL and flashing twrp? Did you follow a guide? Do you have a link?

All good for me except fingerprint (may be due to plastic cover.. will try later after receiving my tempered glass)
I have an mi account which i used for unlocking..
You can create an account then use this link
http://en.miui.com/unlock/
Once they approve they will send a mail with link to download the unlocking software
You should install that, then run it and login in that..
You can unlock it there
install required tools- fastboot ... drivers.. (for me standard android sdk was sufficient...)
After installing those..
You should shutdown device completely then hold volume down and power button at same time to enter fastboot mode
Then connect mobile using cable to your pc
below command should list your device once connected...
fastboot devices
Download the twrp from link given here http://forum.xda-developers.com/mi-5s/development/recovery-twrp-3-0-2-0-t3480133
make sure that its for proper device (mine is mi5s not plus)
if it a zip extract the img file.. then type command
fastboot flash recovery twrp.img
then to boot in to recovery
fastboot boot twrp.img
my twrp defaults to chinese so to change language refer video here https://www.youtube.com/watch?v=KOhR92EKD7A
download xiaomi eu for your device
from here https://xiaomi.eu/community/threads/6-10-20.35693/
Then follow standard twrp flashing guidelines..
You can find it everywhere ( >>> Factory Reset >> Wipe select partitions >> install from internal memory if you already copied it there OR sideload using adb from pc)
PS: (I had formatted system partition as well without issues)
my back button was not working properly but after reboot it was ok..
Thank you very much [email protected] for the explanation.
I will try the procedure today evening when i'm home from work.
Update:
worked fine for me. Thank you very much!
Thanks for all the replies, but went ahead and bought the Note 4 instead. Camera is my only complaint against it, otherwise it's a really great first experience with Xiaomi!

I just bought 5s 128 GB in Malaysia which is directly import (not from official dealer) with Stable Global ROM 8.0.10.0.0 (MAGCNDH) Build MXB48T as per attached. There is no bloatware and quite stable.
Can anyone confirm it is a real global ROM from Xiaomi or a modified ROM?

The additional 0 at the end of the MIUI version and the CN in the MAGCNDH shows that it is a chinese ROM which was manipulated.
So you won't be able to update it, and I at least could not unlock the bootloader because the xiaomi tool did not recognize it as a xiaomi phone....
So I built me a deep flash cable and flashed chinese official ROM, unlocked it and flashed TWRP and xiaomi.eu ROM....

Any Guide for that? Or a video guide?
Check this here, source: http://en.miui.com/thread-390697-1-1.html
Here is what I did to get an official ROM instead of the malware infected 8.6.10.0:
At first I have to mention that using the EDL Method is very dangerous because you will probably brick your phone if it goes wrong.
If you are not sure about something better ask here before doing anything wrong. The phone should have a full battery and save all your files because the phone will be wiped during the proccess.
Step 1. Download the latest official MIUI Fastboot ROM for Mi 5s:
http://bigota.d.miui.com/V8.0.10.0....AGCNDH_20160805.0000.29_6.0_cn_49ab3a5120.tgz
(!!! Important - When flashing the ROM with the Xiaomi FlashTool in the step 3. you have browse into the /images Folder. - Browsing into the wrong folder and flashing wrong files will probably brick your phone !!!)
Step 2. Turn your phone into EDL Mode:
http://xiaomitips.com/guide/how-to-put-mi-5-into-edl-mode/
(Use Option #1 - Option #2 and #3 does not work)
Step 3. Use this Tutorial to flash the Fastboot ROM to your device. Use Method #3 , as Method #1 and #2 does not work anyway with the fake ROM 8.6.10.0.
http://xiaomitips.com/guide/how-to-flash-miui-8-fastboot-and-recovery-rom/
( Skip Step 4,5,6 because your phone is already in the EDL Mode)
This helped me out go get the official Chinese ROM 8.0.10.0. Out of this ROM you can use the MIUI Updater function in the phone to install any other official ROM for the Mi 5s.

There will never be a global ROM for this phone.
It's a China only device.
I still have a little hope that they might start to sell it in India, which typically means there will be a global rom. But so far nothing is announced, so at the moment there is no hope for an official and signed global rom.

My Mi 5s has the same ROM and it works flawlessly. Benchmark results are far ahead compering to those from reviews on YouTube. I was able to unlock bootloader in first try, no problem. If you use Windows 10 make sure to load proper drivers. I don't believe that any reseller is able to compile such perfectly working ROM. It must be Xiaomi that stay behind this, but this is what I believe. As you sad all languages are there and even some you don't find in official global ROM. I will keep this one until official global I released. Be patient.
Hello community, I have a question about my rom:
MIUI GLOBAL 12.0.6 stable 12.0.6.0(QJDEUVF)
Is this global our EU, since it says global but has EU on the name hihihi,
Thanks in advance.
Yours is eea, version for european union. That's when you see eu mark. Other marks: Mi is global, in is india, tr is turkey, ru is russia, cn is china... those Eu roms you mention are china based, so they mostly have either cn or some other stuff. And you have to unlock bootloader to install eu roms. And they have nothing to do with eu, except domain name, and people adopted eu as it's name. They are basically chinese beta roms translated to english and with some stuff enabled.

Thanks a lot m8, it was nice for you to reply.
So to be on the same stock rom so I can lock again the bootloader I should use:
V12.1.2.0.RJDEUXM (MIUI12) our V12.1.1.0.RJDMIXM (MIUI12)?
I'm guessing V12.1.2.0.RJDEUXM (MIUI12)?
Thanks in advance.

You'd need RJDEUXM since yours is eea, but before flashing that one, you'd be better off with finding 12.0.6 rom, return to it, lock bootloader after you've made sure it works, and then update to 12.1.2... I'm not sure that flashing 12.1.2 would work out of the box, because of different partition layout. Also, try and find both fastboot and recovery version of roms, then flash recovery version with twrp first, to get the partition layout back, then full recovery rom should work...

Hello All
I am using Mi11X Indian Variant with Indian Miui ROM - Now I want to install Miui Indonesia Rom with the Same Version

1) Which Way have to choose for Flash - Miflash Software or Direct download and using Recovery Method - also heard even without bootloader unlock can flash ROM - Not sure it is working or not specially Mi11X
2) I read it but didn't find proper information regarding Indonesia Rom - Is there any Network Band issue could face in India, Performance, Camera
3) Which is the Correct way of Flash
4) Should Flash Region-specific Rom or Global Rom would be better
I must surely get an answer at least from someone

You first need to read this great guide by RollDload https://forum.xda-developers.com/t/how-to-flash-a-stock-rom-alioth.4355797/ to understand how to flash stock MIUI in the right way.
I can't answere about device compatibilty between indian and Indonesian
I hope this will help you
Thank you bonerserk for the reference link
First of all I'm not a pro, so do it with your own risk. But, I knew few things since I've changed my Rom back and forth using ID ROM, EU, CN, and many others Custom Rom.
In response of ur questions:
1 & 3. I recommend using Mi Flash Tool. Download the tool, and the required ROM (the FASTBOOT one, since you want to use the ID ROM, there's only 12.5.6 version for the FASTBOOT Rom) using the thread link provided by @bonerserk follow the instructions CAREFULLY.
2. Didn't know the answer.
4. It depends on ur needs. If you just want to remove the Chinese Bloatware, then the Global Rom is suitable since it has less Chinese bloatware.
Thanks, @the.ogeph for the response - After reading the Flashing method come to know Xiaomi implement Anti Rollback features in Some Model - also in Mi11X I didn't get a three-dot option (Additional Features) on Settings->About Phone - Where Some Model has this option - Now I am confused is Mi11X has implemented this features or not? If I Try and stuck due to Anti Rollback then there is no solution available as of now.
Which Device do you have? I didn't find any Mi11X owner who tried this
That's why I recommend you to use Miflash tool. You could bypass the ARB Protection by editing the (.bat) file line command. Just google it or watch tutorial on Yt.
Please follow the instruction really carefully. I've soft bricked my phone once because I skipped 1 step.

Without using Custom Kernel and any other tweek, EU is the best for Battery Life. Try using EU MIUI 13 A12, its quite good for daily use.

No, please do not flash (even Stock Rom with different region) with Miflash tool without unlocking ur Bootloader. I really don't think u can do that.
Yes - Definitely will not try with Locked Bootloader - Once unlocked then will try - But one more thing - After Unlock which Version I Should try of EU Rom - Currently I am using Global MIUI 12.5.7 Version
Unlocked bootloader Receive OTA ? or have to manually Push?
Can I flash EU ROM with Locked Bootloader using Miflash Official Tool? because I am waiting for 10+ days to unlock the bootloader response from Xiaomi
Can anyone confirm please

xiaomi.EU rom is a custom rom based on miui, so you need to unlock bootloader to install it and it didnt use miflash official tool to flash
But I have watched lots of videos where people change Xiaomi ROM with the different regions such as Global to EU, Indonesia, China with the locked bootloaders - for Only Mi11X not able to find any Source
I'm new to xiaomi world, I just received this minor update today, but there are few bugs and lags, I want to revert back.
Both Roms are stock Stable Global EEA.
I don't know how to dowgrade, because recovery zip and update app not work, unable to downgrade.
Can you show me a complete guide to flash that firmware? I need unlocked bootloader?
Anything in particular I have to know?

Hello,
My lisa came with 12.5.5 out of the box. OTA offers direct to 13.0.2. Is there anyway I can upgrade to 12.5.9 ? I don't want to upgrade to A12 atm, or anytime soon really.
Indian firware if that matters.
I see xiaomi.eu has a version of 12.5.9 which is no longer updated, but lisa isn't listed on the compatible device list.
Thanks

First of all, some basics (not sure are you aware of):
1) If your phone came with Indian, you can update but only to Indian firmware without unlocking your Bootloader:
Install MIUI Recovery ROM using Stock Recovery and Updater App
Has your Xiaomi phone received a new MIUI update? Then follow this guide to easily install MIUI Recovery ROM using stock recovery and Updater app on Xiaomi devices. Any smartphone user prefers getting…
www.thecustomdroid.com
In that case you will need to download the so-called Recovery or ZIP stock firmware and use the installation as above
2) For anything else, like switching from Indian to Global or EEA (or to Russian or Chinese) - they are all stock ROMs, or switching to Xiaomi.eu - that is not stock ROM, or any other custom (ie, not stock) ROM, you would first have to unlock Bootloader
AFAIK, Xiaomi.eu has no 12.5 for Lisa, only 13.0 - hence not applicable if you insist on 12.5
To switch from Indian to Global or EEA (still stock ROMs), you will need the unlocked Bootloader, the so-called Fastboot or TGZ firmware (and MiFlash tool):
How to Flash Fastboot ROMs on Xiaomi? - xiaomiui
If you are a Xiaomi user and have installed custom ROMs on your device, then you might be wondering how to flash fastboot ROMs on Xiaomi devices. This article
xiaomiui.net
---
I don't know where do you see 12.5.9 for Lisa - I had 12.5.8 EEA) , but there should be not much difference
Anyway, install the following app and you can check which versions are available for Lisa (for stock Global, EEA, Indian, etc) or custom Xiaomi.eu:
MIUI Downloader - Apps on Google Play
MIUI upgrade app for Mi users.
play.google.com
It shows the Latest but click on Older and you will see all the previously released (stable) versions.
Btw, under Indian, I don't find 12.5.9, neither under Global or EEA (under Global there are eg 12.5.11 and 12.5.14)
From the app, you can also choose and download Recovery (zip) or Fastboot (tgz) stock ROM for the wanted version - depending on your flashing method as above
thank you very much. I did request to unlock the bootloader in the mi unlock app, but all the custom A11 roms stopped development or moved onto A12, so I didn't see much point in unlocking bootloader.
as i understand, if i am on the indian firmware, i can flash the indian rom without BL unlock. but if BL is unlocked, do i need to switch firmware as well to install say the Global ROM ?
about 12.5.9, i mistook it as the last version before they moved to 13. sorry about that.

When you unlock Bootloader it does not prevent you to update India ROM by stock Recovery method
It just gives you the additional option to switch eg to Global by flashing Fastboot/tgz ROM
Its like, you can always go by foot, but if you have a car, you have the additional option to go by car
Please take your time, Google, read to acquire further knowledge and know-how.
There are tons of guides here on XDA, on the Net, Google videos, etc
