Xiaomi Redmi 4X : Basebands

Is there any source to finde latest basebands for Xiaomi Redmi 4X ?
And is it possible to flash it ?
Would be interesting to get any with LTE band 20.

Just updated to new global version 8.2.9.0 from 8.2.0.2.
There is also coming a little baseband update with it.
Before is was .2.c8-00006-8940_GEN_PACK-1_V003
and now it is .2.c8-00006-8940_GEN_PACK-1_V042.
Hope that also band 20 for LTE will come once with a standard update, because the hardware should be fine for it.
Would be great for users / customers in central europe around germany esp.

How can I downgrade the baseband? My 4x only has 2g signal

I have Redmi 4X (santoni) and I b20 was working already when I bought it. Now I use Xiaomi.eu MIUI 8 (Android N 7.1.2) and everything works perfectly.

I 've bought redmi 4x Global from GearBest but I don't know if it supports B20.
The box writes:
Product Name / Product Model: Mobile Phone / MAG138
Can someone confirm if it is indeed the global version and supports B20 ?

I am not 100% sure but I read that few times:
If you got english packaging you should have the international Version with band 20....

There are 3 different Versions to buy.
You can see it eg at geekbuying:
Version 1 : Normal 4x with english and chinese Rom - no Band 20
Version 2: Global Rom 4x with Multilanguage Rom - no Band 20
Version 3: Global Version 4x with Multilanguage Rom - including Band 20

Go to your order at the Gearbest shop and click on the link to the phone.
If you see Global version you have B20, as you can see at the specs (4G: FDD-LTE B1/B3/B4/B5/B7/B8/B20)
Confusing part.......If you see the International version then you don't have B20 (4G: FDD-LTE B1/B3/B5/B7/B8)

unlock bans 20
any way to unlock LTE band 800mh - (20) in xiaomi redmi 4x 2g/16 chinese version????
pls help. I bought this phone but havent band 20
(bootloader is unlock and rom is rooted)

I'm following the same question:
is it possible to unlock B20 on any 4X just flashing the right international ROM or
it is necessary to buy a different version of the phone
(i.e. B20 depends on software only or on hardware difference too ???)

I didn't buy it from Gearbest, it was from one of Czech e-shops. I wasn't aware of the different HW versions.

I think I'm just going to get the Global version on geekbuying with 3GB RAM, $124.99 is a really good price.

as far as i know the problem is not the modem, but the antenna. it needs a different one. you can try to modify the nvram if you know how to do it. you also need B20 configuration values for that. but maybe it really have other hardware requirements.

For Band 20 (EU, Germany) definitely buy the GLOBAL VERSION, on the box it clearly states Band 20 amongst others
China doesn't use Band 20 for LTE, so it's not supported on the China market phones.

Reading from other phones threads, it's not possible to add band 20 to phones without it.
Who tried modding the phone's reserved system partitions, ended up with a non-working phone modem/radio.
So, you must check the supported bands on the phone before you buy it.

[GUIDE] how know the brand of mate 20 pro

Hi, I don't find a complete guide to know the brand of phone, huawei mate 20 pro, but only pieces in many sites.
Here a complete guide.
It's very simple. There's a code on dialer *#*#2846579#*#*, this will open a menu. On menu through - > "network information query" - > "vendor country info", you'll see vendor and country. Models no branded have as vendor hw (it should be huawei=, hw) and as country Eu (for Europe phones, out of Europe can has other voices).
So, if your phone has vendor:hw and country:eu, it's not branded.
If vendor is Tim, H3G, Vodafone, Wind or others, it is branded.
Another method more simple is through build number:
C432=EU
C55=TIM
C113=WIND
ITAC555=H3G
C02=VODAFONE
Every model: LYA-L09/LYA-L29 (LYA=LAYA), etc... Has these codes in build number, and every codes means a different vendor, and obviously C432 means no branded.
I'm from Italy, so I'm sorry for my English, however, I don't know other names of mobile operators, but in Europe if you've C432, phone isn't branded (last huawei's phone models haven't state's firmwares, for example a code for Italy's models and another for Germany's models, but they have code for Europe and others out of Europe and vendors).

C792=Canada (Videotron only?) LYA-L0C - single SIM.

What is C301?
Anyone have firmware LYA-L29 C301?

The US model is Snapdragon, but the N950F is Exynos. You cannot flash firmware from one onto the other, sorry.

verifying your xiaomi mi 9

recently, i bought my mi 9 pre-owned. the former owner says that he bought this mi 9 in china (so it has the china rom in it with alot of bloatwares). so as the title says it, i want to verify whether the mi 9 i bought is original or fake.
i did this by getting my imei by dialing *#06# then putting it in xiaomi's verify website https://www.mi.com/global/verify/#/en/tab/imei
it then gave me this result
"Thank you for choosing Xiaomi!
However, the device you purchased is not an official global version and user experience may be affected. Next time, please purchase the official global version of the device through officially authorized channels."
i have attached a picture of this.
i just want to know if my phone is legit or not because it gives mix signals
since xiaomi recognizes the imei but gives a message saying that please purchase through officially authorized channels.
thank you.

I got this :
So I think yours might not be But I'm not familiar with this tool.
What does the Product Authentification (second Tab) give you ?

maybe because mine is the china version, that is why it is not recognized.
i hope there are more people that try this

You may have the Chinese version so if you try it with a verification that is for the global version you will probably get this error. Have a look at the url and you will see ..../global/... in it.

yes, i see that, but i do not see a chinese or china version of this imei verifier site. so i want to see if other people also see this message

Hi,
I test my phone, bought in a official xiaomi store in Shanghai, when I was there in April and it gave the same answer that yours:
小米9 全网通版 8GB内存 全息幻彩蓝 128GB
Thank you for choosing Xiaomi!
However, the device you purchased is not an official global version and user experience may be affected. Next time, please purchase the official global version of the device through officially authorized channels.
I think it check that your IP isn´t in China (I´m in Brazil) and then give this alert.

To me it seems as if the answer is right. You do not have the global version and since you are tring to verify a GLOBAL version of the Mi9 and you have the Chinese version this is the aswer you are bound to get.

Question What's the difference between submodels?

Hi,
I have 3 spes devices, two are 2201117TL (manufactured in July) and one is 2201117TG (manufactured in January).
What's the difference between all the spes models (2201117TG, 2201117TI, 2201117TY, 2201117TL)? Just manufacture date or do they have differences?

As far as I know ( and I could be wrong ), it's only the manufacturing date ( batch? )
Spesn has nfc, spes doesn't

It could also be the country variant. Like the 2201117TG, G is for Global, while for the 2201117TI, the I could be India or Indonesia (?)
As for differences, one thing for sure is the version of MIUI it has. Because there's like a ton of versions of MIUI for this phone, like Indian, Indonesian, Turkey or Russian ROM

Hmm, yeah that's very likely.
Like I said, I don't know for sure.
