Hi, I bought a xiaomi redmi note from china and I didn't realise that I'd bought the chinese TD-SCDMA version, the UK network frequency works on WCDMA. The seller gave me a full refund but didnt take the phones back so I'm trying to see if this can work or else iI'm just going to sell them.
Now the network does work but can only got up to 2G.
I've heard that the MediTek hardware supports both TD-SCDMA and WCDMA however the WCDMA may have been locked.
Is there any way of unlocking it?
Hi, I am in the same boat too... please share if you find out.
Thanks
Neat Rom in Redmi note
Is it possible to use Neatrom in Redmi Note?
I have the same problem but with Lenovo A808t. This is not compatible with 3G & LTE bands in Spain but, I think, It has the same modem that Lenovo A806.
Can I open that bands?
Hello I'm French and in my country the carrier use the B1 B7 and B20 to connect to network.

Unfortunately you can't unlock band 20 at the moment, in fact you might not ever be able to unlock the band. So if it's crucial for you to have band 20, buy a different phone.
However, it's a really nice phone, if if you don't necessarily need the specific band, then this phone is a good buy I believe.
ok thank's a lot
@ggkameleon,
I don't have this phone (yet ) But, my Telco uses Band 20 too.
What I intend to do is use my sim for phone calls/TXT's and get a 'Pay As You Go' LTE sim for Net access.
If you see the most good chines provider don't use B20 Mezu Xiaomi Lenovo why ? And other use it but it's not the more good smartphone or huawei use it but the price are expensive. When you see the last Xiaomi Redmi 3 Redmi note 3 and now MI5 very good smartphone and not expensive.
Hi din't know what is it a 'pay as you go' ?
But if your telco use b20 you can't have 4g lte in b20 ! But if use with b20 the band b7 or b3 the phone connect to b3 or b7 if ist possible or connect to wcdma in 3g network !
But i can't know why meizu pro 5 use the same soc exynos than galaxy s6 and the galaxy s6 work in b20 ! It's not possible to unlock b20 in meizu?

He meant he'll use a second, prepaid sim to get LTE from another provider who uses a different band. Although it's been said that using the dual sim function on this phone reduces battery life quite a bit.
Yes, if you don't have the correct 4G bands, but do have the 3G or 2G bands, your phone will be fully functional, just not have the best speed possible.
It's not just a matter of having the same soc, it's a combination of soc, radio and firmware. In some phones a workaround can be found to unlock the radio, others not.

Ah ! Ok but if they are a provider don't use B20 go it ! Don't use two provider ? Ok it's not possible to unlock.
Me in my country (France) They are 4 provider Free use 2600 for 4g, but it's a new provider and they are not many radio in 4g and even less 3g I test it's not possible. Bouygues use for 4g 1800 2600 and a little 800 it's the best for chinese smartphones but where I leave there are not radio Orange use for 4g 800 2600 and in radio there are two band in city but in campaign only 800 Sfr use 800 2600 and use a lot of 800 and it's actually my provider. I speak with users of chinese phone the best are Bouygues or Orange because the one don't use many 800 and the second if don't possible to use 800 the phone go to H+ (wdcma 900) and the speed of 4g 800 it's the almost the same of H+ wcdma 900 !?
If I buy a Xiaomi or Meizu I do change my provider but the smartphone do use the 3G Wdcma 900 ! I believe do use it.
The problem now it's Xiaomi block the boot loader of the new phones ? I see the new Redmi note 3 Pro it's a more good quality but It's more complicated to change language and don't use B20 ! I'm disappointed.... I stay to see what Xiaomi make for international customers.

Ok i understand
Yes it's not a good idea to use 2 different provider one don't use b20 and one use it !
Because if you have a provider don't use b20 go for this provider Because you paid 2 provider ! It's just if you are in contract you can make this option but it's more expensive.
In France all provider use b20 ! Only one don't use but there are not enought radio.
Thank you for your message I understand it's to complicated to unlock band and it's possible to use only in 3g.
Yes, too complicated or simply not possible with the hardware. Whatever the case, 3G can be more than sufficient.. I have never done anything with my phone that required more speed than 3G.
However, the phone does have a lot of other LTE bands, be sure to double check if there's not one that matches, it was the case for me.
1(2100), 3(1800), 7(2600), 38(2600), 39(1900), 40(2300), 41(2500)
https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe according to this, there should be enough in france that match to provide normal LTE operation.
Free Mobile is fine for Mi4c you know
I have LTE in outdoor in all Paris (indoor i'm always on wifi)
Thank you for your support and link
Actually my provider are Sfr (because I have a promotion for one year 10€ calls/sms unlimited ans 20go of data) and I do not want to break this wonderful contract
This provider use fifty/fifty FDD B20 800mhz/B7 2600mhz and UMTS B8 900mhz/B1 2100mhz
That good for Xiaomi Meizu FDD-LTD except FDD B20 800mhz
But there are a new problem with Chinese smartphones the Boatloder are lock now
I use Apple phones after Samsung with 3gs 4s and 5s but now the price of their phones are to much and not as high as the difference of Use Android phones ! It's stupid now to buy a smartphone than 800/1000$ it's not possible to my heart and my wife said go out of home if you buy it !!! Paid us a travel and buy another phones. she's right you know.
I like Xiaomi phones and I stay for the mi5......

Wat about other bands ?
i used also my Mi4c with 2 SIM cards (one private with Free operator and the second one with SFR for pro usage). No real problem with 800mhz band used by the two operators.
Ok thank you

The problem will be in a zone where the SFR antenna will deliver 4G only on the unsupported band, you will have only 3G.
That'all. So, it's up tio you to test in the main zone you are, what bands are used by SFR.

Yeah i read all that ...i was hopiing
thx tho....i can still use band 7 here LTE is doing great ...band 4 would be nice for full coverage especially inside building and metro ...
I bought Xiaomi mi4 64 gb from china last year. To my surprise only 2g network was connected and no 3g and LTE. I don't have much idea about it. I live in India, forget 4g, if there is any method through which I can connect my phone to 3g band I'll be grateful. If someone can explain me how to unlock all 3g bands and that will possibly connect the 3g band of India, it will be of great help. I have already used the phone in 2g network for a year and it's pain in the @ss. I found recently that by unlocking it is possible to use global bands. PLEASE HELP!!!!! THANK YOU!!!
Did you buy TD-LTE version? FDD-LTE is used in most countries.
Most probably YES
Probably Yes. Otherwise the problem of network might not be there.

Hi team,
It seems OnePlus is showing different frequencies on the 5G band for phones sold in China (IN2010) and Europe (IN2013).
IN2010: Bands 41, 78 & 79
IN2013: Bands 1, 3, 7, 28, 78.
Does anyone who if a Chinese phone originally intended for IN2010 bands are flashed the international ROM IN21BA, are the other bands accessible in Europe . Other bands being, 1,3,7,28 ect.
Or is there a hardware lock?
It's technically programmed into NVRAM, but the publicly found version of QPST doesn't support this device, so I don't know of a way to modify the bands.
1,3,7,28 and 20 are 4g LTE bands in France, so Europe. It's not 5g bands
These bands are presents on the IN2010 model too

Shame, when Europe starts using band 28 on 5G, the Chinese imported phone won't support this band then.
Also i recommend compare 4G and 5G Combinations between China and Europe variant:
China: https://cacombos.com/device?model=IN2010
Europe: https://cacombos.com/device?model=IN2013

In France B28 used for 4G LTE for now but i think they will transfer it to 5G like other countries. That will be low band 5G for many countries to build coverage.
I'm wondering if we can unlock additional LTE bands in k30 Pro chinese variant for people who bought the Zoom version. I read it can be done on old devices and bands are not removed by hardware, only locked. Here you can read some examples:

I hope an expert can throw some light about this and if it can be done on modern devices.
Not having band 20 on vodafone or virgin makes no difference in the U.K. This was an issue years ago as Europe only used band 20, Europe also use band 1,3 and 7 so really isn't a problem anymore. Please search what bands your country uses, it will more than likely use 20 still but the others will also be available. I'm using the zoom model.

Well, if you're living in Germany band 20 is essential. Otherwise you won't have signal on the countryside.
So I'm also quite curious about unlocking different lte bands especially on the k30 pro zoom edition.

Same applies for Netherlands unfortunately. I might just go for the global Poco F2 Pro but I kinda want the Zoom edition lol.

the above link was posted 5 years ago, I'm not an expert but I tried every means possible on the OnePlus 3t, I was also told by people that knew more about it than me that it couldn't be done.
I tried on my old galaxy S4 never been successful
Looks like it's impossible on our phones - QPST sees the phone, but can't do anything with modem memory. Maybe because it's encrypted.
I don't really need band 20, but LTE-A band 7+7 or 7+3 is very needed. In Chinese 2020 models Xiaomi cuts off CA 7+7 support for some reason. My Redmi K20 holds LTE-A CA 7+7 easily.
