Xiaomi, firmware and LTE bands - Xiaomi Mi 4

So In another forum someone mentioned that xiaomi phones with qualcomm chips do have LTE bands used in the west like band 4 AWS, but are disabled by firmware because of licensing costs and those bands not being used in the target market (china and other asian countries)
Is this true? and if it is has anyone found a way to change the firmware to re-enable those LTE bands?

there is a lot out there about it im gonna dig deep into it when my phone arrives just picked up a mint condition for 135 guy had it listed as mi4i but the pictures showed me different
it does have the bands
people have been able to successfully enable them in baseband but they did not get lte i asked what rom and kernel as they can play a roll also
if youd like i can share my bookmark links lots of reading

[Q] Huawei Ascend Mate 7 LTE Bands

Can someone tell me which bands the phone supports. There has been conflicting information and I want to know if there are different models to look out for.
According to Huawei the phone will support FDD LTE band 1/2/3/4/5/7/8/20/28. However the China websites that are currently selling the phones only list band 1, 3 and 7. Is this a mistake or is this different model?
You ask Huawei?

THIS is why I'm waiting until someone figures this out. There's been a lot of discussion around this. Has anyone tried emailing Huawei and asking them?

band 1/3/7 is the only bands available in China, but when the phone is roaming(using on other carrier than CMCC, China Unicom or China Telecomm), all other bands are usable.
Not sure what you mean

Thanks, but what does that mean? You don't specify whether this will work on (as the question asked) on the AT&T US or the T-Mobile US networks for 4G and LTE capability.
If you can provide that information and backup as to where that can be found that this device is compatible and will work at 4G LTE speeds on the T-Mobile or AT&T US networks, I'd be a lot more sure about what i was getting.
Thank you though for responding.

I made a post on the main level of this thread, please go look.
Huawei's current offering of phones is NOT compatible with US 4G LTE bands, they will be releasing one soon (don't know when) that WILL be compatible.
I asked them directly and they responded from the manufacturer directly.
My suggestion, wait until they put out a US-compatible phone.
i don't know WHY none of the press bothered to point this out, useless in total if you ask me. They screamed and oohed and aahed over the device and failed to mention that the one being shown AND being produced currently is NOT compatible with the US-market. Another model that Huawei says is, will be released (no ETA).

Oppo r7 Plusm LTE inquiry

Hi,
I'm new to posting on xda, been using it for advice for ages but this is the first time I haven't been able to find my answer. So I'm going to apologize if I've posted this in the wrong place or done anything else incorrectly right now.
I ordered an R7 plus from Taiwan and received it a few days ago. A great phone, i am entirely in love with it. I can put up with the bits of scattered chinese in the settings as i will be flashing cyanogen as soon as it's available. My problem however lies in the connectivity. I didnt know a whole lot about wireless data before ordering the phone, but what little I did know I applied to my research and found that all three variants of the phone should work on my providers network. I have the Taiwanese variant, which does supposedly support the 2100mhz, and 2600mhz frequencies, which i believe are bands 4 and 7, anyway, these two frequencies are the frequencies my provider uses. Rogers uses FDD with 2100 being up and 2600 being down. Yet in the phone settings when selecting which LTE band 4 and 7 arent options, there's USA Band (Im unsure what this really is, I assumed it was 4 because much of the us uses band 4), 6, 33, etc. And I havent been able to get LTE to work. The APN is configured correctly. All anyone's been able to tell me is that it should work. I can provide any more information you guys need, but any help would be greatly appreciated.
Edit: For more info- My provider is Rogers, i have also tried it on Bell (still only 3g), and Wind, which works the majority of Chinese phones and it didnt even pick up their network. Any advice would be great!

Aws-3 band 66???

Wind, now Freedom Mobile in Canada has lte frequencies with AWS-3 (band 66). How can I get this on my oneplus one? Can I flash a new modem?
No. The phone doesn't even support Band 2. It will never support new frequencies.
The hardware in the Oneplus one (and 3) does support the new bands, and the antenna required is trhe same as for bands that are already supported, so the only thing that is missing to be able to do this is a firmware update

Ok, but as we've seen for other bands (for example lte band 20) it wasn't enabled over the years, so maybe there's anything hardware-related too?
I think they just don't want to devote the development effort. This is why I wish open source firmware was a thing....

Honestly I dunno if it's a hardware limit or a development "limit". But I've seen a lot of experimental things on OPO thru the years, so maybe I believe that people who can do that exists, but hardware is the real issue.

Changing LTE bands

I purchased a Honor View 10 from Alibaba a couple months back with the international build (BKL-L09 8.0.0.131 C636) installed on it. I however live in Canada and the LTE bands installed in this version don't work in Canada. I just saw they finally released the View 10 a couple of days ago in the US and the band's will on the US version will have the LTE bands that will also work in Canada. My question is what is the US model of the View 10 and is it possible to unlock the other LTE bands?

I think you need rebrand your device to a US variant
I emailed Funky Huawei and they said rebranding will not change LTE bands. Unless of course they are wrong...
really? It's bad news for me. I have Chinese version view 10 already.

Rebranding will not change LTE bands!
A phone's bands are physical. Just take a look at one of jerryrigeverything's phone teardown videos and try to spot a long wire(s) going around the inside of the device.

Actually the LTE bands can be unlocked but not via rebranding but changing (or updating) the kernel. The bands are only locked to a specific region via software which is related to the kernel of the device. Rebranding only helps with receiving updates for a certain region but you gotta change the kernel.

I really don't know if it would be just something in kernel, but until EU version isn't on 8.1 we cant test or propperly compare kernel source.
We know Kirin 970 is capable for all frequency, because P20 is out only as one version for all markets,or at least for EU/US
Maybe with this way it is possible to rebrand from US to EU and get LTE bands

Did you solve the problem? I am in the same situation but with a P20 Lite
Actually.. You don't need the kernel
It's in the modem.. That's what dictates what bands your radio received.
It's that easy on Samsung.. It's that way here.
Wee used to flash different modems from different regions on the same model.
Trying to figure out a way for a universal flashing technique in these phones as most of them are the same with only the region lock and recovery check.
Since most of these phones contain the same modem, that's what needs to be done.
Trying to see if I can switch identifier in modems.. If I can fool the checks into thinking one modem is the same region for another
I have an Honor View 10 (global) that isn't working on the LTE bands in the US either. Is it possible to use the North American firmware and flash the global phone? Would that gain access to the LTE bands? Thanks.

I have a US Verson of V10 and not working LTE with some carries in Brazil... Works only on band 3, but here, the carries use 3, 7 and 28. Can you want to change your phone with me ? Rs [email protected]
So, did we figure out how to change bands on View 10 ?
I'm in Canada and using Rogers network. My device is bought from India BKL-L09
I have set the region to Canada
The LTE is working and showing
My problem is that the download speed is horrible (will never exceed 8 mbps).
I've switched my SIM in other devices and I'm getting up to 100mbps.
Any advice?

Three Network Versions

Hey everyone,
the new Zenfone 6 is amazing, besides the FlipCamera it has nearly everything (big battery, microSD, 3,5 mm headphone,...).
Just one thing irritates me: there are three Versions A, B and C, as one can see here under "Network Standard"
https://www.asus.com/Phone/ZenFone-6-ZS630KL/Tech-Specs/
So can someone tell me what that means? Like if I get the European version A (with Band 20), will I than for instance not be able to use it in the USA for telephone / SMS?! Or just not LTE / can I still use it like on UMTS? No LTE at all or just not certain carriers?
Hope someone can make it clear to me, thanks in advance
You'll be able to use it anywhere, it's just there's slightly less band coverage, so some networks in some countries would be nixed.
See Kimovil.com for network compatibility.
Gearbest currently have the 6GB / 64GB Version C (most bands) for €495.
It means you'll have to be sure to verify you get the version with the bands needed for your particular carrier. You have to be very careful and verify before buying as it seems with the ZenFone 5Z, for example, sellers don't always properly clarify which version they're selling.
You need to find out which of the main bands your phone carrier uses then match them up to one of the versions. I use AT&T prepaid, so for for example I need a phone with coverage for bands 2,4,5,8, and 17 if I recall correctly.
If some bands aren't covered you won't have LTE in that area, as not all areas you're in are using the same network frequency bands. Therefore coverage can get worse when you travel with a phone without full band support.
Checked out the bands available on the Asus site you linked (thank you very much BTW) and it seems they are missing bands 66(extension of band 4) & 71 (600mhz frequency) so it seems like it may work okay on TMobile.
What do you guys think if those two bands are missing? Will it be detrimental to daily use or not really? Currently on an OG Pixel and this Asus offering is looking like a future purchase!!

Looks like the C variants might work for you but double check the bands for your carrier Kimovil.com.

Thanks for the hint.
I need Band 20 (O2 Germany), so I can only use Version A (so no B or C for me).
---edit---
I just checked: T-Online and Vodafone use Band 20 and 32 (in Germany), but none of the three versions support both.

Ok, but does it mean I will at least have telephone and SMS in those areas, where the LTE band won't be supported?!

Yes, as long at the other bands are supported (which they should be) it will drop to 3G/4G or whatever. That's why people using some Chinese phones for example in the USA can use everything but LTE.
You might
need to check however about VoLTE, I think. I don't have T-Mobile but you should read more about that as I've seen it mentioned in XDA & other places.

I only see the A version there. Where did you find the C version?
This device just hit my radar... looks like we might have an upgrade winner!
For Tmobile US, C model is the way to go. The two highest bands that are missing with this device would get you better signal indoors / less interference, but I am not sure how far along that tech even is.

By highest bands do you mean 66 and 71? The only phones that use band 71 at the moment are Samsung s8 Active and LG V30. I currently have an OG Pixel and it does not use 66 or 71 and I get great coverage in the East coast even when going north into the mountains.

Yep, those are the two. Those two are still relatively new, and general Tmo coverage continues to improve here in Colorado.
I imagine that once the phone is sold on the asus.com website that particular variant will support all the main carriers LTE bands. I would be surprised if there were any major issues with that otherwise what's the point of even selling it in the USA?

Yes, for example in the case of the 5Z I just ordered (to get me by since I desperately need a phone with a better camera & no OLED to cause eye strain) the bands listed for phones at the Asus USA online store cover AT&T properly and to the best of my knowledge T-Mobile as well.
I figured out that they don't list phones there that aren't USA network compatible. I still check, regardless, just to feel 100% sure but that's what I found.
It's the 3rd party sellers you really need to be careful about and always verify.
The OnePlus 7 pro has bands 66 and 71.
This probably would have been my first choice until I noticed the different versions. With more and more manufacturers choosing to release single, global bands phones, I really don't understand why Asus insist on continuing to release regional versions of their phones.
Back in the days when everyone made regional models, I had the Padfone Infinity 2 and it was a great phone (until a late OTA release have it the new ZenUI, which was promptly removed). After reading that the latest ZenUI 6 has been slimmed down to an almost stock Android experience, I thought it might once again be similar to what Asus provided before ZenUI came along and that I can now once again consider Asus phones. Wrong!
I spend time in both Europe and Asia and there is no version that covers both areas major LTE bands. So Asus will have to remain on the list of phones to ignore.

I'm in the same position. The C version covers everything I need except for Band 20 which is a necessity throughout Europe. The A version has Bamd 20 but won't work on US LTE. They did the same thing with the Zenfone 2 and inexplicably mixed up the bands regionally. I'll stick with my NexS for now but keep an eye on this phone in case the Limited edition they usually release solves the problem.
