Can i buy in china (during my trip) and install a Global ROM?

Hello everyone,
as per the title, can i buy the mi mix 2s in china from a local seller and then switch it to a Global Rom?
Will i encounter bands problem for example? i live in EU
Thank youu

Yes, you can just install the global rom, I'm living in germany and also got the chinese version. You may check what LTE bands are used in your country since the chinese version does not have all the bands the global version has. However, the extra bands the global version has are mostly used in africa and america so chances are good that you'll be fine

Are you entirely sure that the two versions come with different bands? I can't find any confirmation anywhere

Yes they do come with different bands. I do not recommend you buying the chinese variant!
Look for the model that ends with XA ! this is the Global one with all bands.
Trust us. There is a reason for different models to exist.

The Chinese model can install global ROM but you cannot lock bootloader afterwards so it is not safe and many apps will not work.
Global model has more bands than base Chinese models but same as 8/256 Chinese model.

You can, but it would be "better" to buy it and install a rooted ROM from here if you want full features like Android Pay to function.
You can't relock the bootloader if you change from the chinese ROM.

Yes you could, but that may be not suggested depending on the model you want to get...
For 6+64 / 6+128 models, China variant (XE model) differs from global variant (XA model): XE has less band support and you need to keep your BL unlocked to install global ROM. So you'd better not buy these two models in China.
Still, I can show you the missing bands on XE model if you'd like to know, but anyway I don't think it necessary to buy it...
For 8+256 model, there's no two variants, only one XA model for both China and other countries. You should be safe to buy it.
And, if you get XE variant and flash global ROM with BL unlocked, you still cannot install Magisk - you'll see bootloop and then enter recovery. That's another important reason why I don't recommend XE variant. The only way to install Magisk is to install MiPa kernel instead of the stock one.

Unlocking the bands on an Indian 8T (KB2001) possible?

If I have an Indian 8T (KB2001), would I be able to install a global/beta ROM (if and when available) and be able to unlock the bands so that I can use it in USA? 5G bands (n71, n41 , n260, n261) and bands 66, 71 is not available in the Indian version but present in the US model.
Just wondering whether a software update would turn this on as I believe it's the same hardware but the software hides it? Just a wishful thinking on my part, of course.

Unlocking 5G-bands is not possible. Phone example missing mmwave-antennas so n260, n261 bands doesn't work and I think it's not ready for even low bands. n41 may work this model.
In US I recommend buy US-version of this phone.

i want to use n41 in Indian model KB2001. I am in Thailand using this device and not able to connect to 5G as AIS uses N41 Band. can you help me with unlocking N41 band on this model.. ANy guidance?

I bought indian version, also want to unlock other 5g bands.
Is it possible if I just change DA rom to AA?

No way unlock without recompile modem firmware... If i know right all unlocked variants (China, India, Global, US) have same modem firmware so rom changing doesn't help. But you freely try and report here.

Convert OP 8T Indian variant to EU

Greetings
I need your help with steps to change my OP8T Indian variant KB2001 to EU version.
Reason: bought it from Indian friend and I live in a different country.
Please advise.
Thanks

Just do a local update with a newer EU rom and it will be fine.
The Indian hardware probably won't support all the same 5G bands that a legit EU phone would though.

Question Difference between variants?

Last week I bought the A53, and today I noticed I received the Indian variant (SM-A536E).
I'm from Europe and I bought it from a verified European shop.
I was wondering if this could have any disadvantages?
Like maybe the Indian ROM has more tracking than the European One (because of GDPR or something) or the Radios are different?
Could I for example flash the European ROM through Odin?
Thanks

The biggest difference for most people is going to be the supported frequencies, especially the 5G bands.
For example, I considered getting an international model shipped to me here in the USA (because the USA models cannot have their bootloaders unlocked without exploiting bugs) but decided against it because it wouldn't support one of the major 5G bands used here.
That's the only part of your question I can help with though, I don't know what would happen if you try to flash firmware from a different region.

Enabling bands for the Oneplus 8T Chinese version

If I buy the chinese version of this phone and then change the ROM to the global one. Would I be able to unlock the bands for my country? What are the bands that are blocked by hardware and can't be umblocked no matter what?

Bands can't be changed via flashing to another ROM. They are locked in hardware.
