Xiaomi Mi Mix 2 global version

I'd like to buy a Xiaomi Mi Mix 2 which is currently available only in the chinese version (sold with the chinese MIUI). I read that soon it will be on sale also in the global version (with the global MIUI out of the box). I was wondering if the only difference between the two variants is the firmware included or there are other differences

Just the ROM. You can unlock the Chinese version, and flash the MIUI EU or Epic ROM right now and have something very similar to the Global ROM right now.

Thanks, so if I flash the official global MIUI when it will be out it would be identical to the one sold as global version and I'll be able to get the OTA updates?

Presumably.

They just announced 2 hours ago that's it coming to India on the 10th. We can probably expect an official global ROM around that time.

I believe the English Version version at https://www.gearbest.com/cell-phones/pp_786413.html is the global version. It support many frequencies for AT&T and T-Mobile in the US.

I bought that one, and it is the Chinese ROM, but the hardware is the same. I registered my phone with my MIUI account and was able to unlock the bootloader three days later. Now I am running the EU ROM and everything just works.

+1 Same here,another from GearBest.
As you mentioned,the hardware is the same across the board,there are no region-specific models,just like with OnePlus & their latest,the OP5.
Only internal hardware variations are w/RAM & Storage,the rest is identical,no matter where you buy it.

If the original rom has chinese and english and I want to use english anyway, why is everyone changing to the eu or global roms?

You have less Chines grap on your phone (apps)

Remove the all the Chinese apps, and several things like Netflix and Contacts just work better (or at all).

[Q] I have a mountain of questions before I decide to buy this phone :)

Hello everyone,
I have got a mountain of questions that arised from reading the forum and a lot of different topics.
I'll have numbers on them, so if you can/want to only answer a few of them you can refer to the number.
1. I've read about this ARB quite a lot, what's the deal with that if I want to go to a custom rom?
2. I understood that it matters where to buy the device in terms of an unlocked bootloader (TradingShenzen seems like a good place to start). But if I can't get my hands on a phone with unlocked bootloader, can I unlock it myself?
3. I'd like to go with the xiaomi.eu rom, any advice on how to get there? What I mean is, should I choose a CN model or is a Global model better, does it matter? What steps to take regarding TWRP and avoiding ARB, etc.
4. What does GSI stand for? I haven't found any thread explaining what that means, and I'm quite new to xiaomi devices (would be my first one).
5. I've also seen that there are quite a few different variants of this device, do the roms for it just work on all of them or do I need to check if the model is supported? (That seems to be a bit different to other phone vendors)
That's it for now, please don't kill me if some of the things have been answered before, I haven't found an answer to the questions so far (the infos that I got so far were insufficient)
Cheers,
Zacki

1 Google introduced ARB, a safeguard to not create an older version of the system from the currently released. If you install the official older version of the system for a new one, you will wall your phone.
Does not apply to Custom ROM
2 You can unblock the bootloader yourself on the official xiaomi website. It takes about 300 hours
3 unlock the bootloader, install recovery, install xiaomi.eu. Global rom is more stable, but xiaomi.eu has more personalization options. Recently, xiaomi.eu does not cause problems on Mi Max3, but it causes problems on other models.
4 GSI https://source.android.com/setup/build/gsi
5 Mi Max3 Global 4gb RAM 64gb internal memory,
Mi Max China 6gb RAM 128gb internal memory
You can install the Global ROM on the china version if you have unlocked the boootloader, and remember about the ARB. Otherwise, you will wall your phone
The Global version is popular.

Thanks for your reply.
@1. Interesting to see what Google is up to with things like this...why would they want this?
@2. Thanks, but whoa that's quite some time...and I guess I can only trigger the 300h AFTER I bought the phone, right? (Why so many hours actually...?)
@3. I've read about the changes they made to the rom and I like that. But what do you mean with being "less stable" than the global rom? In what way? I'd like to use that as my daily driver if I get it (not the weekly builds of course).
@4. Will have a look, thanks :good:
@5. I was actually looking at the 6GB/128GB version of the phone, if I can convince my wife to allow me to spend ~260€ on a phone (I'm currently a student ).
In this case, I'd already have an unlocked bootloader and if I want to install the rom from xiaomi.eu, there should be no problem, right? Also regarding ARB, this should be fine, right?
And in what ways are the CN and the Global versions different other than the rom? Are there differences for the supported bands or radios? I live in Austria, can I use the CN model here without any downside?
Edit: I'm having a look at this particular model, it would be available with CN firmware or with Global firmware. Would that still account as CN model in this case?

Google thinks people should use the latest system because it provides better security.
Xiaomi introduced a long wait time to unlock the bootloader, because dishonest sellers offered CN versions outside of China and India by installing the Global system on it. The CN version is only for China and India.
Xiaomi.eu provides its system every week. Contains various patches and additions. Sometimes something does not work, payments, BT paired in the car, notifications etc. In my phone, the last two versions do not work Gmail notifications. In today's version, people write that OK Google is not working.
If you unlock the bootloader, you can install xiaomi.eu. The ARB will be kept at the level of the official system you had.
The CN system contains only Chinese and English. It does not offer Google Play, it also contains full Chinese software.
Version 6/128 is only a CN model. If the seller offers with the Global system, it means that he has unlocked the bootloader and installed the Global system. You naturally lose the Xiaomi warranty.

So the xiaomi.eu roms don't have any of that ARB stuff, good to know. Could I technically install an older version of that custom rom without triggering the ARB or is that not possible? Just so I understand that.
And how is that with other custom roms? I've read in some threads that you have to make sure you have the correct ARB if you want to flash that particular rom, why that?

I'm not worried about the warranty but more about the specifics of the device. Is the CN model different in any way that it may not work properly with the providers in europe? Or things like that?
And sadly that vendor does not seem to have that version in stock at the moment, so I was thinking of getting the regular CN version of the device, that's why I'm asking

As for xiaomi.eu it does not contain ARB, but there are exceptions. If the phone gets an update to android 9 - xiaomi.eu must use the full original xiaomi firmware from ARB. The next versions on the same adroid no longer have files responsible for ARB.
Current level of ARB = 4 from Oreo to Pie. What you can not do:
to install MIUI9,
to install Miui Global on a CN version phone with a locked bootloader
block in the bootloader if you have Miui Global on your CN
install Miui China on a Global phone and block the bootloader.
Custom GSI roms do not have an ARB, you can install anything.
Mi Max 3 in the CN version in addition to the system and memory does not differ from the specification from Global. Will work in Austria.

So if I get the phone with Android 8.1 and I want to get MIUI 10 (Android 9) I need to update with the official rom and then flash the xiaomi.eu rom?
And while we are at that, if I buy the CN variant, do I have to upgrade to PIE with the CN official rom or can I also do this with the Global rom to get ARB to 4?
And what't the deal with the developer versions of the original roms? I've read something about them but would that help me in any way?

it's not like that. You do not need to update the system. Xiaomi.eu is built with miui china developer extended to additional language translations, optimizations of softu for Europeans and a few additions that occur only in the Chinese version of the miui.
The whole system, firmware and kernel is miui china. If you install xiaomi.eu then you install the entire system, with the firmware and kernel. They are suitable for the android version.
You can have miui global Oreo and install xiaomi.eu Pie. Everything will be updated.
Miui Global is available in Stable and Dev versions. Dev-Beta is a development version released every week, contains the latest security, system fixes and errors detected in the Stable version, as well as new additions that are tested and do not always have to work correctly (like the development version of xiaomi.eu). As developers will correct detected errors, the stable version is created.
I just installed myself Global dev. I like it more than xiaomi.eu. Everything works so far. I usually use Global dev, and xiaomi.eu tests once in a while.

Some block the bootloader from ignorance or inadvertently.
When installing a new ROM by MiFlash, you have the following options:
install and block the bootloader (by default selected)
clean everything and install

the parameters of the telephone accessories and the frequency ranges of the network are the same. The difference is 6gb RAM, 128gb Internal memory and MIUI china.

Interesting, because I've read somewhere that the normal and the dev version are more or less the same, just that you have to use the dev version in certain situations to "unbrick" because of something with the bootloader (but I don't actually remember the details).

If you have an unlocked bootloader then you install twrp and flash xiaomi.eu

Using dev to unlock the bootloader affected old phones. Currently, it does not matter. Rom useful as well as Stable.

Miflash is used to install only official miui Rom, you use the rom .Tgz package
It installs through Miflash with the cleaning option. It does not leave garbage in the old system.

If you have xiaomi.eu then china rom does not matter.
You can look for a seller who offers a phone with downloaded xiaomi.eu or miui global - to choose from
in the past, the sellers offered the china version.

Can anyone confirm this number of hours?
Cheers

Usually it is 720 hours, but I checked it every now and then, after 4 days, this time has decreased by half.

It's 100% not decreased or changed it 720 hours. Unless you had a mi account before an unlocked a phone

That is an interesting note. I created an account a few days ago, when I ordered the phone. Does this already count as "having an account before trying to unlock"?

there is any global official ROM available
THANK

Right now there is no official Global ROM for download, there is only the official China ROM from Nubia, and Black Magic 5G custom ROM which is a Global Clone based off of the official China ROM release, it's very close to being a Global Clone from what I've been seeing but haven't been able to get it working on my 12/256 Global. The only things I know so far is Black Magic 5G Doesn't have an App Drawer or NFC working yet, but given how ambitious the Dev is, it shouldn't be long before this is fixed.

I was looking for something related to ROM's but I can't find anything.

Hello
Not sure why you want to change to global rom. But if it's for calls and text messages to work in the USA. You really just have to fastboot flash the non-hlos.bin file. Which is the modem. If it's cause you want nfc and your a cn version phone. Never gonna get it. Nfcis not on the cn version at all. And it's blocked by a script. I can give you the non-hlos.bin file I flashed to get global phone services. But a warning!!! If you flash this file you will not receive ota updates. And if you do. It will fail to update. Apparently when I flashed that modem. It changed how the phone recieves ota updates

Yes, you can, I also have the Chinese version smartphone, but had several problems, including in the 4g that had no network.
Simply download version 4.09 and put in the main directory of the phone, go to update, click on the three dots on top right and choose manual update, then you choose the downloaded file and update without problems.

Question LE2120 Chinese variant has Indian FIrmware ((LE15 DA). Is it possible to change it to global firmware?

I got my 9 pro yesterday and it has indian firmware which i don't like. Is it possible to change it to global one. I'm on 11.2.5.5.
Also is it possible to use msm tool for Indian variant on this handset?
Thnx. Really hoping to get some answers

It should be, you should be able to download the global firmware from OPTeam's list of them and just flash in local update.

Yes, you can.
The only problem is 11.2.5.5 is too new, there is no full upgrade package yet. You can try flash an older global version rom, but with the risk of brick your phone. Through I think worst could happen is you have to wipe your phone.
You can find download link for global rom in this thread.
Q: How do I switch to Europe or Global OS?
A: Wait for the new version, download the #Full package and Local Update it. If you have Magisk installed, you can try to Local Update after entering the following command (need ROOT access).
resetprop ro.build.date.utc 1400000000
Click to expand...

That's my case too.
I'm also in the 11.2.5.5 Indian SW.
So it's better to wait for a Global 11.2.5.5 or newer to flash over it? Right? It's not necessary to erase all data?
Does someone know what are the benefits from Global over the Indian? It seems that OnePlus is giving more attention to Indian market (updates, features, etc)

From what I can tell, there is no discernable difference in the firmware other than bloat directed at the Indian market. I'm also on LE2120 in the U.S. running the DA firmware. Everything on my device is fully functional as far as WiFi, 5G connectivity and all that. I debloated all the Indian specific bloat (red cable club, cloud storage and the like, especially since it doesn't work here in the States). I expect you can flash other regions firmware without issue or data loss so long as the other regions firmware is "newer" than what you're already on, otherwise it simply won't let you using local upgrade.

I'm also on LE2120 in the UAE running out of box coloros, then downgraded to the DA firmware, today I have updated to Global 11.2.5.5 . Everything on my device is fully functional except 5G (ETISALAT) and Invalid VIP NV's:2500 at every restart

Question [Poco F3][MIU13] Why no custom ROMs are using the latest firmware from MIUI ?

Hi, I've seen most ROMs recommend firmware from MIUI 12.5.x and not the latest is there any reason for that ? Does the latest firmware could break something ? Or lead to weird bugs/new bugs ?

A11 miui based roms have hit their end of life for the most part (12.5.19) almost all the bugs have been worked out and is very stable. Imo, as well as many others, the A12 based miui roms are sometimes if not always missing import features such as face unlock (at the time of writing this). The A12 based roms, imo, are not the most stable roms for the poco f3 atm (I've tried both, and ended up sticking to 12.5.19 xiaomi EU stable)

Oh interesting so we're kind of a lab test for the new firmware in EEA, I thought China would have been the test case first and then they would deploy it to others ROMs (Indian, EEA, Global, etc.) once it is stable enough
