Mi A2 vs 6X for use both US&China - Xiaomi Mi A2 / 6X Questions & Answers

I'm currently looking into buying a mid-range device that runs or can be flashed to stock android as a backup. Since I have both Chines SIM and US SIM I'm trying to buy a device that can support the net works in both countries, specifically China-Telecom.
So my question is, do both A2 and 6X support China-telecom? And has anyone been able to unlock the LTE bands on the 6X for use in the US?
I noticed there are pixel experience roms for both devices and they are maintained by different people. Are there any major differences between the two roms?

Xiaomi MI 6X in europe?

Hello everyone. First of all, I apologize if this topic is not in this section, since I am new to the forum.
I write because I'm considering the purchase of a Xioami MI 6X. I live in Europe, and I know that this phone is a Chinese version. As it is not yet known if the international version will come out (Xiaomi mi A2), I decided for this phone. Why?, because the design, processor, memory, etc ... I know that the REDMI NOTE 5 is very close but I still prefer the MI 6X. The question is, since I live in Europe, and this phone goes with a Chinese version, how difficult would it be to put an international ROM ?, that is, given that on the xiaomi website the international ROM of this phone does not exist, I can install a ROM of any other phone? or it is imposible? And second, is it so serious that it does not have an 800 band for 4G? I have seen that the phone have the other two European bands for the 4G, but not the 800.
Thanks.
The only European store avaible are in France and Italy but they don't have that version of the phone for the moment and maybe they will put it in the future because is recent, for the band this are the supported band: Quad Band (850/900/1800/1900). Becuse isn't avaible the 800 band I suggest to change the model to buy for another from the same producer but with the features that You need it.

Hi,
For this phone it exists a translated rom from xiaomi.eu for each european language, I'm french and I'm not yet decided to buy this phone but I think I will. 290 Euros 6G 128G red version.
Xiaomi.eu uses chinese developper version, debloat it, add playstore and many features.
Updates comes to your phone through OTA weekly the most of the time!
It's very easy and fun, each week an update.
As the phone is updated weekly the phone seems to be more stable with this rom than... Stable global rom! ahah!
To install the rom you have to unlock the bootloader and install TWRP.
The most difficult is to unlock bootloader if you haven't xiaomi permission for your MI account. I had to use a browser trick with a chinese proxy to obtain this permission but you have to do this only one time for your account and can unlock three phones by month. For each new phone, you have to wait 3 days after linking a phone to your MI account in order to obtain authorisation to unlock the bootloader of the new phone.
[Edit] For the 4G problem, it isn't a real problem and sometimes it's an advantage to not have B20 (800Mhz).
In France, I live in a little village without 4G, most of small towns around me have the 4G with the B20 only. I've got a MI5C (withoutB20) and a MIA1 (with B20). The phone without B20 is more efficient because in small towns it turns automatically in H+ or 3G and I've got a very good connection whereas the MIA1 is in 4G with a very bad speed because all people are connected in 4G!!!!!!
When I go in a bigger town I've got 4G without B20.
Conclusion: Without B20 the internet connection is better because you don't use the same antennas as all other users!!!!

That model also shows FDD-LTE Band 4. Seems like a typo. Only mi 6x listing that has band 4.
Unless there really are different mi 6x versions/models.
4G should not be a problem
Now the A2 and the A2 lite will soon be available in Europe. I would recommend getting one of these devices. - You will pay a bit more, but You will get warranty. Nevertheless, I recently bought the 6X for my GF, she does not mind MIUI, which is the major difference between the 6X and the A2. You can get the 6X from China, and flash an xiaomi.eu ROM, and it works very well.
The major concern about 4G should not bother You that much. Check what bands does your operator use and support either on their website or on wikipedia: https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe
if Your operator uses only B20, then the phone is not for You - the A2 should support it, tho.

Hi,
I am looking for your solution but does the xiaomi.eu ROM support well OTA common update and major MIUI version update through OTA ?
Thanks
Mi 6x stable in Europe
hi guys, I've bought a Mi 6x in China in May. (128GB/6GB on stock English MIUI 9.5.15.0) It's stable in Europe, almost 100% on 4G, because one of the bands is missing it switches to 3G in certain area's. I like the phone but want to turn it into an A2, haven't found out how to do that. If anyone knows, please let me know.
Hello, thanks for your info, I have recently bought a 6X and I would like to switch to french, could you please let me know if it's possible and how , I am an amateur in this field

French is not available at the moment, the only European language available is English currently
You can search at xiaomi.eu there You can find muli-language transtated roms, and I would say regular ota, plus beta miui builds.
Hi to all
Do anyone flash A2 rom on mi 6x?
Is it possible?
Please share your experience...
i do. already two weeks for daily use and its ok. but i dont know if its OS run fast or slow because my previous phone was iphone 5c with ios 10.3.3 and the far i can say is the OS Android One 8.1.0 is not slow like i feel the same with ios 10.3.3
According to the thread on miui.com OTA updates doesn't work. It also bricks you device if you have anti_roll 4

K20 Pro not compatible with T-Mobile. Which ROM will fix this issue?

I didn't do my homework good enough and found out the uncompatibility (can't use mobile data, only voice/text) after I got the phone. I think I will need to flush the phone with a different ROM.
Does anyone know which ROM I should use, so that the phone will end up working with T-Mobile data network?
Thanks.
David
Are you sure?
I don't have this phone but I've had this issue with Xiaomi phones in the past, it turned out to be the APN settings.
I think it wasn't able to get the APN settings from the network, I found something online about my provider and it gave me 3G after I put it in. Then I found another APN for my provider and I got LTE working too.
k20 pro doesnt have bands 2 and 4
the newly released mi 9t pro (which is same as k20 pro) has bands 2 and 4.
i am not sure if Xiaomi has locked the bands on k20 pro with software or it's a hardware thing. if you can , return the phone

T-Mobile tech person was trying to walk me through to set APN. That didn't help. Eventually he asked for IMEI number and checked compatibility, which came back as only compatible with 2G for phone calls and texts.
Any moment 9T Pro firmware will be released, because the phone was released today so just way for it i think.

does the mi 9t pro firmware unlock the bands on the phone ?

I put a mi 9t pro ROM, MIUI Global 10.3.3.1 Stable 10.3.3.0 (PFKEUXM) on my K20 pro.
It boots up fine and runs fine, except, I can still not connect T-Mobile beyond 2G. When using a China Mobile SIM card (which connects to AT&T network), the status page shows HSPA,
So this seems to be a bad news, that bands 2 and 4, which are supported by Mi 9T Pro, seem to be hardware locked, that using a Mi 9t pro EU ROM does not unlock them.
Anyone has any other suggestions?
Thanks.
That is correct, hardware bands are locked into the chip and cannot be unlocked. Return the phone or sell it, if it really doesn't support the bands you require.
Btw. in which country are you? T-Mobile operates in many countries and with many different bands. Typically you should get 3G, unless you are in the US I think.
Yes, US. This phone supports Band 5 and I see Band 5 is on the T-Mobile support band list. But further check shows that T-Mobile uses band 5 for extremely limited use.
Oh well. Will look into selling it used.

Question Modem: Possible to Convert China 512gb to Global 512gb in terms of bands?

Is it a software thing that makes the band selection different between the two variants?
Is it possible to flash Global modem to China version to get the Global bands? or is there a physical difference?
OR
Does anyone think Xiaomi will come out with a 512gb global version in the future?
The different bands are hardware, there's nothing you can do about it.
Also, no, 100% they won't release any global 512gb version in the future.
Years ago there were some Qualcomm tools called QPST Tool and QXDM tool or something like that. I read they were used to "unlock" additional bands... But like I said, that was years ago, so no idea if it would work on the Mi 11 Ultra. Probably not.

Even if adding bands would be a thing...how many more does one even need? Basically all bands are there (except 66 which is prolly a us band).
It's cheaper for them to make one phone from a production standpoint than make ones with different bands for every market they plan to sell it in
I am gonna buy a Xiaomi Mi 10 Pro 512gb 12gb ram version, however there's no person ... "I just talked to our technicians, and maximum probable it's going to now not work and if it does then you will ... With the frequency bands as this cellphone is fashioned consistent with the Chinese ... Currently on miui international 12.Zero.3 QJZMIXM I'm in Australia if that matters.

Question CN or Global (EU) Phone ?

hey there fellow XDA Members and Mi11 Ultra Owners!
Any downsides of buying the CN Version of this Phone over the Global/EU Version?
i've got the MiMix2s and have there the issue that it got some new Baseband FW someday that now produces issues in the EU Network... also other Phones from xiaomi had this issues that the CN Versions where somewhat troublesome
I bought the china version and when it comes to google integration, it's very limited what you have.
your apps and messages won't automatically sync, there is always the chinese apps that you can removed, but the AI stays there.. I installed the global version and it's like a normal google phone, everything will be download it to your Mi Ultra 11, no need to download each app individually, . If I was you, i would spend the little extra money it cost fot the global version and get it.
Just get the CN phone and flash the EU Rom.
Honestly I recommend buying the global version as internet bands differ from the Chinese version at hardware level, so no firmware can change that. Many people didn't find this an issue anyway,but I would recommend you to stay on global

I've not seen any changes to radio bands in any specs. I would have thought that they would not change the modems hardware antennas for different regions? If you have some specs showing the different bands can you let me see them or a link, I'm really interested if they have.

AFAIK bands are identical this year.
5G works here with CN model so I'm good.
Bands are different, sure you have 5g but you may miss something on some specific carrier
As far as I know, the hardware is identical
You can Check your location and carriers on kimovil.com
I posted a website where you can actually see the bands used by both versions,they are different, also on these pages in the thread "where to buy the mi 11 ultra" it's been posted many times, it's where I heard of it

But the hardware can select the bands from the modems configuration per sim and network location required to the maximum bands built to be used per model. See all the mi 11 ultra configurations in the screenshots taken from mine.
Mine is not rooted, but it would be good to see the modem config from a global hardware sold phone and a Chinese hardware sold phone both using the same ROM to see if there are any difference's in bands using the Qualcomm modern config app. I would be happy to be proved wrong but I bet both have the same bands, just applied different.
No rom or firmware can change the bands sorry
This is my first post so forgive any stupid errors or remarks ! I bought a Mi 11 Ultra with the CN Rom. I'm waiting for the bootloader to unlock and I was going to install the EU Rom. But I have been using it after taking off the bloatware and to be honest it's behaving and works well. The 5g speeds are good and it seems to change between 4g and 5g smoothly when moving about. I've attached a screenshot of a speed test done sitting in a coffee shop on Tottenham Court Rd London. No over heating and camera works well. So I'm seriously considering leaving it locked and using the CN Rom.
But willing to hear why that's a stupid idea!
Thanks

The CN ROM works well if you're patient and don't mind debloating and tuning it to ensure all Google apps work as it should since it does require some tweaking. For example, I remember my Google Pay didn't initially work.
I remember getting 150Mbps on LTE+ with EE in London Bridge station over a month ago which was fantastic although I heard the EU Weekly runs a bit more efficient with the memory management and process allocation. What eventually sold me was the fact that it was based on CN Weekly betas, and those occasionally get camera improvements first before stable across all regions.

I purchased the China version as well, maily because it is a lot cheaper than the global variant. I then wait a week, unlock my bootloader and flash the Xiaomi.eu rom with full Google integration. You see, the Xiaomi.eu rom takes the roms from China and removes all the Chinese bloat and script and then adds in full Google functionality. It's truly the best of both worlds.

Question MI 11 Ultra Chinese's Version QUICK help please

Quick help please
Im trying to buy it here in UK MI 11 Ultra Chinese's Version
What is the difference is it worth it
Can i install global firmware on it
Will i get 5G on it im using UK network
Thank you
https://www.wondamobile.com/mobile/xiaomi-smartphones.html. You pay no import tax with wonda.
You will need to unlock the bootloader to change ROMs to other. That takes 7 days. If you want global, why don't you search more local? Then you won't need to unlock the bootloader?
Yes, 5g works but depending on your network and availability. Check your supplier in your area and check the band's available on the phone for fullness before buying.
I'm in the UK, can't get 5g, none around me but 4g is dam fast. I am using the Xiaomi EU ROM, it's a custom ROM based on the Chinese but fully Google and safteynet supported. Pop over to the Xiaomi EU forums for more info.
