will rn4x China version work on LTE under Global Rom? - Xiaomi Redmi Note 4 Questions & Answers

First of all, thank you for paying attention to my question and sorry if my English is not good.
Hi, im from Chile and I bought a RN4x Global with Qualcomm, but the network works terribly slow. I just discovered that the phone originally had the China Rom (Box is half Chinese half English) but it was flashed to Global Rom by the man who sold it to me.
May that be the reason why it is so slow? (I mean, may the network be so slow because it doesnt work under the LTE band of my carrier?)
In short: If someone flashes Global Rom on a Chinese version phone, should it take the same bands as a originally Global version phone?
Thank you very much for your answers!

Hardware wise, the Chinese and Global versions of mido (your device) are identical. They should both support the same modem bands no matter the ROM version. If the global firmware is installed then that is the best you can do. But you could always flash the global version yourself just to be sure, though I can't help with that - there are already heaps of guides out there for that.
Not supporting certain LTE bands that you carrier needs won't make it slow - it will either work or it won't at all. Problem must be elsewhere.

Xaomi Redmi Note 2 TD (china Version)

i have bought Redmi Note 2 TD but seller did something and this TDD support FDD :/
Now my Question is this safe for my device hardware?
Will this Custom Firmware be bad for my device in long term of use?
And if i Install official Rom from MIUI website will i lose FDD bands and will i brick phone?
Really i need more info about this TDD/FDD china version hope someone will respond and also this trhead will be good for future buyers
I have TD version (2015052), with FDD bands.
FDD bands is supported out of the box by factory, but it is not usable in China market.
I have 3rd rom flashed on my RN2, without any problem.
Just avoid to flash china rom, dev or stable-only for safety feeling.
Good luck

Are you sure about this?
I bought the TD version in Hong-Kong by mistake, it worked perfectly in China with China Mobile 4G, but now in Taiwan the data isn't working, I can make phone calls but cannot have any data (my plan is 3G).
Do you have any idea why? or how to put it working?

Probably because you have china rom. Maybe you can flash multilingual from http://xiaomi.eu/community/threads/5-11-5.28947/, and (I believe) you can use TW (FDD) bands, but only on one SIM slot (of your choice).
I bought my TD version by Aliexpress, from HK also.
In advertisement they say that after flashing their (idk if only?) rom, device have FDD bands enabled.
I put on my device all published roms for redmi note 2, except China roms, without problems.

Try in engeneer mode (type *#*#3646633#*#*) > Telephony > BandMode>SIM1 under LTE to check bands 1, 3 , 7, like in pictures:
And try to put SIM in other slot...

Confused about China vs Global

Hi all,
I'm considering getting a Redmi Note 3 (Snapdragon version/Pro). I'm a little confused about the bands that it supports. When I check wellmyphonework.net it says that the Global model will work on LTE Band 4, but the China/Unicom one will not. Looking in the forums I see Global and China Roms, but nothing definitive about separate physical models.
Is the hardware all the same(ignoring RAM/Storage variations)? Do the supported bands depend solely on which ROM is installed? If there are distinct hardware versions is there any way to tell which one I would get from ebay or AliExpress?
Thanks in advance.

The lte band support is hardware dependant, software doesn't matter.
I've bought mine with China global and lte is working fine in Europe.

That's simply not true. The SD650 supports Band 4 which is what he's asking about. Europe doesn't use Band 4 and all the versions support European lte bands. On another thread here a user with AT&T was getting lte on the vendor rom and changed to the Global rom and now only gets H+. I too would like to know which version of the phone I have.

Moving from China to Indian Firmware.

Hi guys,
I just bought a Chinese version of the X820 and I was wondering how do I move from China to Indian firmware? Do I do it via the updater and download the Indian firmware and renaming it to update.zip? (Not rooted)
and another question, which is better, Chinese or Indian version?
Thanks.
Yes, you can. I have flashed rom 16S X821 India for my mobile. Everything is ok.
Thanks. Which is better for you?
Hi, wanted to tell you that I moved from the chinese to the indian to the us version, didn't use the indian one, but between the us and chinese, the us is better as it doesnt have as much bloatware (for the rest is pretty much the same)
I had problems setting up the APN for my data on the Indian version tho. The China one was fine. Is saving APN working fine on the US version?
I didn't have to do anything after flashing the US one, so I would say that it just works.
Do all LTE bands sill work, whichever firmware you use?
Don't know about all of them, I'm currently in Asia, and this this had originally the Chinese version, flashed the us and still get 4g in Malaysia, Thailand and Singapore.
I'm inclined to think that they do work no matter the ROM.
Btw, I was trying to go from Chinese 14s to US 16s and it got stucked in a boot loop, so I flashed again the Chinese, then went to the Indian one, I think 15s, and then the US one, it worked without an issue that way.
Now i'm using CN 16S. I have a problem with 4G+/LTE-A in Malaysia.
When it switch to 4G+ coverage, all phone signal include data and call will lost (Can't use at all)
No toggle switch to turn off 4G+ only, but able set preference to 3G to run without signal drop (Only HSPDA)
Now my containment solution of this is :-
In Malaysia, telco using CA for Band 3 and 7 for 4G+. The coverage for Band 3 is higher than band 7. So i disable the Band 7 to stop the phone switch to 4G+, I still able to enjoy the 4G of Band 3, rather than only set to 3G (HSPDA)
Anyone with better solution, please let me know. Thanks
Hey, I'm from Malaysia too. Had the same issue. You got to make a new APN. Eventho it looks like an APN has already been set, it still won't work. I find my LTE to be working again after I set a new APN.

Is the Le Eco le max 2 x829 going to work in Europe, Romania ?

Is there a major difference between the x820 and the x829 version? From what i could find on the internet the x829 is the version for the US and i'm not sure if it has bootloader unlocked, considering the 64 gb ROM i would risk buying it, but if lte wont work in Romania on this version, and there's no way to instal another custom rom thats a no buy, please tell me your thoughts
P.S. sorry for the basic language i'm not a expert in this field

You can look on this site: willmyphonework.net
There you can choose brand,model,country and your provider.
Website mentioned does not help, as you can't select variants.
As far as I know (I have ordered it myself) X829 is USA version, so it DOES NOT HAVE BAND 20. I would skip on this one if your 4G/LTE carrier is emitting via B20 frequency.
Here in Montenegro, 2 out of 3 carriers have 4G and both use bands 3 and 7, so I am covered and don't really care about B20.
There is a tool that unlocks bands, yet nobody confirmed that it actually works.
As far as custom ROMs are a concern, they all are interchangeable , means all ROMs can be used on all variants, X820, X821, X823, X829...

Cheers mate ,now i know what to look for, not so many informations on the internet about the phone variants...

Thank you it will work it uses band 3 and 7 just like in montenegro so no problem there

I have x820 working perfectly in Lithuania, you can check your Country's LTE supported bands on this link; http://willmyphonework.net/ and hardware for all version of max 2 is the same, you can always switch between roms.
Most webshop are pre-selling the X829 and will ship fom Feb 28, let's wait a few days to have them in hand and have actual experince on whether they have B20 and if they can be unlocked. (I want to know also if they do)

Sorry man, but are you sure that I can use a x820's rom on x829 version? Because there is an awesome x820 rom by cuoco92
Hello in an German Forum a user told that all Roms are working for the X829 and the LTE Band 20 have been unlocked
And than he said he was mistaken, 'cose his phone was x820, not as he belived x829
There's no proof b20 is gonna work - yet.

Yes, he got his Phone last friday. He wrote, the unlock with the DFS-Tool is done like the manual description. He can't test the LTE-Band, because he havn't a SIM with LTE. He is waiting for a new SIM to test the x829. DFS-Tool shown a unlocked B20
link it here, bitte
Has anyone tried the x829 in the US CDMA carriers like Verizon, if it works on them it will be e killer deal!

which honor 9 model?

Hi. I have a galaxy s8+ which I am thinking of selling to get this phone - mainly because of treble support and the s8+ is too big! I was going to get the 6gb/128gb version which is great value on ali express. I know the Chinese version doesn't have band 20 but that doesn't matter on EE in the UK.
However I wanted to check whether there are other issues with not getting the European version of the honor 9? Does the Chinese version support the new aosp treble based Rom the devs have built? The thread seems vague on this issue. Other there any other issues with the Chinese version?
Appreciate your help.
As far as i'm aware, you can actually re brand the Chinese variant to EU.
Not sure if the version of android on it has Google Play services, or an English language selection, but language packs can be downloaded.
BUT! you will get the OS updates before us lot with EU versions.... who are still stuck on B182, China have got B360 which is oreo.
Either way, its a good buy, destroys the s8 in benchmarks, and just the right size to not be too small or too big in the hand.
There 3 differents STF Chinese honor 9:
AL00
AL10
TL10
I've got an AL00 rebranded to L09 and it's working great, like an European model but without LTE BANDS 7(2600) & 20(800).
Thanks for the responses. I thought the Chinese variants of the honor 9 were the same as Xiaomi - only missing band 20? I'm on EE which doesn't need band 20 but I believe does need 2600mhz (band 7). Any ideas? Thanks
https://m.gsmarena.com/compare.php3?idPhone1=8704&idPhone2=8704#europe,al00
You could change phone version on this link, I think LTE BANDS are corrects but there is errors on size and colors.
Thanks. EE state that most of their 4g coverage is with band 3 so should be Ok! Thanks for the responses guys.
I wouldn't expect huawei to use a different LTE chip in each phone, that would require 2 different versions of the kirin 960, which wouldn't be in the interests of the development cost of the phone.
I'd assume its an OS limitation, since AL10/100 firmwares will run on L09 models after rebranding, and vice-versa.

I'd like it to be true.
Do baseband is inside Kirin 960 cpu chip or in another chip?
The way I see it they ship differents variations with differents nand & ram sizes, so maybe they could switch others things without adding tremendous producing cost.
Or they are the same but phoned still keep their original LTE bands over the publicly available rebranding guides.
