Thanks for this information

I have found an interesting program on play store but it don't work yet for Redmi Note 2:

I'm not 100% understanding how these TDD models with chinese bands are set up to have access to the FDD bands.

The key question that I would appreciate an answer to, which would help me decide whether to buy a TDD model, is: If I buy a TDD model from somewhere, and install the xiaomi.eu rom, will it still have access to the FDD bands?
[Redmi Note 2 General] spydo97:
Yes, xiaomi.eu rom is FDD rom.

TDD model can install this rom and will have access the the FDD bands.

On Taiwan forum, it describes that TDD model only lock the China carrier sim card.

Taiwan user can buy a TDD model without flashing FDD rom and can access to the FDD bands.
[Redmi Note 2 General] JakobiE:
Thanks for the information! Did you try it out yet?
[Redmi Note 2 General] spydo97:
I had bought a TDD model. When I got it, I flashed it to the EU(FDD) rom.

And it can access to the FDD bands(B1/B3/B7).

So I didn't try the methond 2 that is deleting the file and couldn't check the FDD bands could access or not.

kornelio6 installed this rom too, and it works.

I have posted this tutorial already here. It is just for Qualcomm devices and we have a Mediathek chip, but perhaps someone can find some similarities which help us.
[Redmi Note 2 General] reflex9000:
the TD Version supports FDD/WCDMA out of the box, you dont need flash every other ROM.

i think the ROM self have nothing to do with the bands, this is deeper in the System, so you must look in the Source Code.
[Redmi Note 2 General] Okluzhion:
I always forget their other models have SD chips.

[Redmi Note 2 General] ferlie:
Yes... Thats right... I buy TDD version but can use FDD without change anything. Even using original MIUI ROM
[Redmi Note 2 General] TziMmysGr:
If I undesrstand correct, the chipest td version suports 4g sims in both slots? Becouse this the the diference.... By doing nothing? Out of the box? Can somebody confirm this?
[Redmi Note 2 General] reflex9000:
yes on both slots 4g, but not at the same time,

example. Sim1 use 4g, in Sim2 only 2g available.
[Redmi Note 2 General] Klanac89:
I can switch but when I switch, the other slot will change to only 2G

Maui meta appears to be a nv editor for a mediatek device... Will it work with our phones, I don't know? Anyone use it before?

http://forum.gsmhosting.com/vbb/f457/update-maui-meta-3g-v8-1512-0-relesed-1962204/

Want to check it out this weekend, just haven't had much time at home.

Edit: I installed CDC Drivers and Maui Meta. I was unable to get my device to boot into Meta Mode and auctually read any of the information from my phone. I was on my cheep Windows 10 Tablet, so I wouldn't be surprised if driver compatability is an issue.
[Redmi Note 2 General] SkiFire13:
That's because you can use 3g/4g only in a card at the same time
[Redmi Note 2 General] poks999:
Maui meta was supposed to be only for MTK65xx devices, not MTK6795. Not sure if it would work on the newer chipset. Maybe someone might update it? (I can dream)
[Redmi Note 2 General] andy775:
Maui meta appears to have been updated to support 65xx + 67xx series according to my research... I've got windows 10 on both my computers, and it seems like that might pose a bit of a incompatibility. Windows 7 seems to be preferred. I'm a bit busy this weekend, but might be able to check into it a bit more next week. :/
[Redmi Note 2 General] Xmister:
I already tried it, but it wasn't possible to unlock new bands with it, only the factory ones were available.
[Redmi Note 2 General] andy775:
Thanks for the heads up, I kinda figured you've already been down that avenue.
[Redmi Note 2 General] lowspeed:
So what's the verdict? can we have this work on At&t LTE?
[Redmi Note 2 General] Gerrit507:
I have a letv one which also has the X10. I extracted the modem files of a european M9+ rom and was ending up with a disabled mobile network and a even worse wifi...

I and also other letv owners would be really grateful if somebody could find a way to unlock Band 20, which is very important in Germany and also other european countries, especially if you have O2. I only got 4G in three places so far and it's weird because even if you move within a city you find places where 4G is available and some places which only have Band 20. It is supposed to be only used in rural areas but O2 uses it almost everywhere, because you can cover larger areas with lower frequencies.
[Redmi Note 2 General] Xmister:
Actually, based on a similar effort for oneplus one,there's another hw required for unlocking frequencies other than the soc.

So it's very well possible that the reason we can't find a way, is because it's not possible to do in software.

I'm not sure, as I don't know the exact hardware configuration of the device. It's just something we should be aware of.
[Redmi Note 2 General] andy775:
Mister, have any reading on this extra required hw?? Would like to read up a bit more....
[Redmi Note 2 General] verbage:
Partial yes--2G and 3G/UMTS will work, but not LTE. AT&T has 2G and 3G/UMTS service on 850 and 1900MHz, and the RN2 has those bands covered. But no, AT&T's LTE bands are not covered. From my perspective, it's not that bad because 3G/UMTS includes HSPA+, which can go pretty fast, in fact so fast that some people call it 4G. But you'll have to make the call yourself.

Somebody asked about T-Mobile yesterday, and I posted some links with info. I realize you asked about AT&T, but some of the links provided include AT&T info, too. Thread is at:

[Redmi Note 2 General] Xmister:
Here is the guide for unlocking bands in NVRAM on QCOM, however, as you can see there are some bands (including B20) that cannot be unlocked due to hw limitations, even though the SOC would support it.
[Redmi Note 2 General] lowspeed:
This this phone have a qualcomm chip for the radio?
[Redmi Note 2 General] Xmister:
No, the SOC is mediatek, so is the radio in it. However there is another HW piece that is needed for the bands, which is independent of the SOC.

Probably some frequency amplifier, or something.

Note 2 Prime has band 20?
[Redmi Note 2 General] reflex9000:
no!
[Redmi Note 2 General] chris5932:
If its not possible in NVRAM it is likely to be a hardware restriction, as for other phones it generally works that way..

Any one still trying or has ideas? someone from miui would probably be a big help..
[Redmi Note 2 General] maitrot:
Does "Band 20" mean the bandwith is 20MHz?

The problem is the kernel source, without it nothing can do...

~ Xiaomi Redmi Note 2 Prime ~
[Redmi Note 2 General] Gerrit507:
The kernel source is already on github https://github.com/jawad6233/MT6795.kernel
[Redmi Note 2 General] SkiFire13:
It isn't complete...

~ Xiaomi Redmi Note 2 Prime ~
[Redmi Note 2 General] chris5932:
Thats why we need miui to release it or help us..

I am afraid that the device is not popular enough to get the complete kernel in a decent time frame. Sometimes I wish the old htc hd2 times back :rolleyes:
[Redmi Note 2 General] maitrot:
Absolutely. All I know about LTE in Europe is that it either uses 800MHz or 1,8/2,6GHz base frequency slot multiplexing. AND I really don´t know how broad the used spectrum is,

hence my question.

Since people in this thread seem to understand what they are talking about I just threw in this question. You know the stupid question/stupid answer theorem, do you?

The broader the spectrum, the higher the data rate a I/Q split based receiver has to tackle. Maybe the hardware is really restricted in this case. Timeslot muxing seems therefore less hardware demanding.
[Redmi Note 2 General] Gerrit507:
There are two different versions of lte. FDD LTE and TDD LTE. Frequency Division Multiplexing uses different frequencies for up and download and is very common in Europe. Time Division LTE transmits upload and download with time offset. It is very common in China but very very rare in Europe.

The higher the frequency, the higher the bandwidth and the lower the distance the signal travels.
[Redmi Note 2 General] MikeFRG:
There is no hardware restriction the CPU can handle it and the integrated LTE Modul ( http://www.skyworksinc.com/Product/3065/SKY77643-11 ) also
[Redmi Note 2 General] chris5932:
it should be nvram issue then
[Redmi Note 2 General] Xmister:
If the leaked baseband source has anything to do with our phone, then there is some info about B20 in it, but it is not properly defined, and without documentation it can't be fixed. (At least without reverse-engineering some info about the SOC and modem)
[Redmi Note 2 General] jack_21:
Stonex One (a phone "designed" in Italy and produced in China) has mt6795 SoC and supports band 20...

[Redmi Note 2 General] chris5932:
we would need baseband or better baseband-source of a mt6795 device with b20, right?

elephone vowney could be helpful aswell..
[Redmi Note 2 General] SkiFire13:
I think Stonex is more open-mindedness about modding

Well, letv one is not redmi note 2, although it has the same soc.

Chance of success from straight flashing the M9+ Baseband is quite low I must admit..
[Redmi Note 2 General] Emmes:
As already posted in another thread, the source code for Sony's M5 Xperia (also helio x10 with LTE Band 20) is available to download:

http://developer.sonymobile.com/dow...1-33-30-0-b-1-33-30-0-a-1-35-and-30-0-b-1-35/

I ve also found a firmware image for this device:

[Redmi Note 2 General] andy775:
I like it! Good find!!
[Redmi Note 2 General] Xmister:
The kernel can bring us closer to custom kernels. However the baseband source is not in it (obviously), so it can't help much in this regard.
[Redmi Note 2 General] freestart:
Good news I hope that sameone can find a solution now
[Redmi Note 2 General] jack_21:
So Sony got the permission to publish the helio x10 kernel source code from MTK ?

Why Xiaomi not?
[Redmi Note 2 General] PytSkee:
The kernel source really doesn't matter as far as unlocking the baseband unless the code for that is also included, right? And even that matters very little unless we have tools to determine the code unlocking other bands. Some genius would basically have to find the unlock code in another phone's baseband source code.
[Redmi Note 2 General] chris5932:
One we have the redmi note 2 baseband source and another phone (with band 20) baseband source it shouldnt be too tough (if it is possible by hardware).
[Redmi Note 2 General] yousad:
I also played arround with the nvram (Meizu MX4 - MediaTek MT6595). Looking at it with Maui is almost impossible to understand where to begin.

[Redmi Note 2 General] tailslol:
i think it is more a problem of copyright and licences issues... for example the redmi note 2 sales have been baned in india because xiaomi have no right of selling mediateck devices in india...

so it is only legality stuff.
[Redmi Note 2 General] chris5932:
I dont know what this has to do with releasing the baseband and kernel sources..
[Redmi Note 2 General] tailslol:
i am just assuming that xiaomi have no right on using some bands in some country because of obscure reason,or they are implementing limitation in the phone to artificialy limit the interest of importing them.

if i remenber mediatek didnt allow xiaomi to release the helio x10 sources code.

but they did.
[Redmi Note 2 General] chris5932:
We dont need them to unlock it, we can do it ourselfs (if we get the sources).

Did someone try Xperia M5 baseband?
[Redmi Note 2 General] mrsurge:
What about the m9+? Has anyone tried the modem from that device?
[Redmi Note 2 General] SkiFire13:
The m9+ hasn't got the band 20...

~ Xiaomi Redmi Note 2 Prime ~
[Redmi Note 2 General] mrsurge:
I'm really concerned if using a different modem could work at all, I have at&t (band 17,5,2&4) which the m9+ supports. If someone could get the m9+ modem, I'd be willing to give it a go, and see if its a modem firmware issue in the first place.
[Redmi Note 2 General] icyalias:
I just got my Redmi Note 2 a few days ago, I bought the TDD-LTE version, seems it has exactly the same bands as the FDD-LTE version. I've also flashed the latest rom from xiaomi.eu and have not lost any bands. Seems they are unlocked permanently

Bands are in the modem... And xiaomi.eu use the modem of the FDD-version

[Redmi Note 2 General] SkiFire13:
Blu Pure XL supports only band 2, 4 and 17...

~ Xiaomi Redmi Note 2 Prime ~
[Redmi Note 2 General] felix168:
I speak Chinese and here is the issue with Xiaomi not supporting other areas where they don't market directly.

Xiaomi is huge in China. Like Apple, there are Xiaomi shops all over China and in their market area. Real Xiaomi phones can be bought at Xiaomi shops. Xiaomi even made a huge announcement telling people to buy its phones only at Xiaomi shops or its official websites. And like Apple, if there is a problem with your Xiaomi phones, within the warranty period, you can simply just bring it to any Xiaomi shops to get them repaired or replaced. And that's the major reason why people who bought from 3rd party sellers aren't getting much support. And perhaps that's the reason why they're not unlocking all bands.

---------- Post added at 05:59 PM ---------- Previous post was at 05:54 PM ----------

You do know that the BLU Pure XL is a rebranded phone, right? The originally supports all the rest except for 2, 4, and 17, which uses the same exact Helio X10. For the U.S. market, they do 2, 4 and 17 (however, 5, is missing).

[Redmi Note 2 General] felix168:
I spoke with someone from a tablet manufacture (not Xiaomi) in China, and was told that network frequency bands can be unlocked before the devices were assembled regardless of which processors were used. And of course that person would not tell me how it can be done. Personally I have no knowledge in this area. It seems impossible for us peasants to get this accomplished.

[Redmi Note 2 General] chris5932:
I don't understand what you are trying to say in the first sentence, sorry :-/

As long as the chipset does support the band it is the software that enables it (after assembly).

Well, reading the discussion (link above) there are bugs. Sadly I do not understand a lot of what they are saying about it. As much as I understand "HenGe_" camera, bluetooth, gps communications, something else does not work
[Redmi Note 2 General] felix168:
I don't understand which part you didn't understand, sorry.
[Redmi Note 2 General] chris5932:
I guess I don't understand what the support of band has to do with the assembly. If bands are supported by hardware they should be able to be unlocked?

Did you have a look at my links and can tell us what they are saying? :)
[Redmi Note 2 General] felix168:
your link to ariafan4pda was just a fans' page. it only showed the 24 fans that he/she has. then I looked through it and he/she has what seemed to be 10 files that was shared, but I have no idea what they're for. there was no discussion, no instruction, and no direction. just plain files for downloads, I supposed.

http://bbs.ydss.cn/forum-hongmi_note2-1.html <-- this one was however more useful. there were a lot of different topics. But so far I haven't seen any that's related to unlocking the network bands.

:eek: and now you just got me to enroll into yet another forum...
[Redmi Note 2 General] chris5932:
I know that first link is just a fanpage, I think ariafan4pda leaked the kernel source tho (see in his files from march). In his friends I found lbule who build CM and is apparently some kind of developer. What do they say about CM on his weibo and on baidu? Maybe we should ask lbule whether he has any idea about the band stuff.

Thank you for checking out the links ;)

I wasn't able to create an account in the forums, phone verification doesnt work for me..

We should be looking for radio source, I think its unlikely that the chinese devs have focused on unlocking bands.

It has some interesting things, e.g. MIPI Customization shows a code of defining Band20, but it's for MT6290, and it can be seen from the other bands, that it's different, so actually won't help.

Anyway these documents are much more about calibrating the given phone(power, voltage, etc), than about defining/modifying basic functions.

Also the more I look at these, the more it seems the baseband firmware is completely in the files in firmware directory that is configurable through nvram.
[Redmi Note 2 General] chris5932:
That is quite disappointing, took me hours to find it.

So we need something about nvram/mt6169? Lets see.. I am sure there is something, the problem is (for me) to identify what we can use..
