What really controls active LTE bands on the x50 phones? - Windows 10 Mobile

Little background. I own a 950 XL RM-1116_15357 and 650 RM-1152_15514. I began wanting to enable VoLTE on these phones and the IDOL4s I also own. I succeeded on the IDOL4s. When I started in on the 950 XL I enabled LTE bands that it did not have as stock out of the box. It was not too surprising to me though. When I did the same thing on the 650 though, it was surprising since it was a cricket phone and spec-wise has less LTE bands out of the box then the 950 XL (1, 2, 3, 4, 7, 8, 20). I am seeing this via Field Test app. For the record I enabled these on the 650 while trying to get VoLTE to work (LTE: 1, 2, 3, 4, 5, 7, 12, 13, 20, 29, 30, 41).
So my question would be, are the newer Lumias made by Microsoft limited to band configurations only by sw? Or is Field Test app misleading?
What seems to enable the bands is the modemconfiguration.cab file under \PROGRAMS\CommonFiles\OEM. Thanks.

I am going to propose an anser to my own question. For the 650, 950, and 950xl I am going to say that the available LTE bands are in fact manipulated/enabled via the modemconfiguration.cab file. I say this because I have first hand used different modem files on those three phones and changed the LTE bands that are avilable via band locking. I am now using a 950xl that has band 29 and 30 enabled with VoLTE/HD voice on AT&T, which is not default for this model.

You can upload here that cab?

Attached the one off my 950xl I am using now.

Hi, i used imgmount tried to copy modemconfiguration.cab file from RM-1154 under \PROGRAMS\CommonFiles\OEM\Public\MMO\Multivariant but it's always pop-up an error of 0x80070780 : The file cannot be accessed by the system.
May you share how to copy the file under Windows system ?

There many other threads to help your situation. This is not that kind of thread. I suggest you look into the InteropTools and sftp file system access threads.

Has unlocking these bands improved your coverage? Or does it give you more bars?

It is hard to say if it improved or not. Because we are changing something it does not ship with out of the factory. The bands show up and are "lockable", how well they work it would be difficult to tell. Try it and see what you think. At the moment I am on VZW so I cannot really test it out.

meaning you probably have/had a 928? which is known to have band 4 for LTE but disabled, and forever waiting for it to be enabled
maybe you can try enabling it? I tried fieldtest and it showed nothing really, other than letting me lock on to 2g or 3g, on a 640 it was more functional

I had an icon and a lumia 735. Sold those and have the Elite X3 on VZ right now...

how did u enabled band 3 and 40 on idol4s they donot have modemconfig file please help

I never enabled band 3 or 40 only VoLTE For AT&T. The OEM phones like Alcatel and HP seem to hard code the EFS data LTE/GSM/etc at the factory level. Lumias are setup different.

I would be very thankful if you tell me how to enable all that lte bands on the 650!
Sorry for the off topic

that i was thinking too

[Q] Enable certain LTE bands on Lumia 640

Is there a way to enable an LTE band on Lumia 640?
As far as I know, Lumia 640 supports all LTE bands, but they might differ in certain models (RM-1072 vs RM-1073). It'd be great, if there was a way to enable LTE 3 and 20 bands on RM-1073, like it is possible on Nexus 5 (D920 - D921), using field test.
I wanted to know this too.

UK version of HTC 10 Compatibility with US networks?

Hi
Quick question from a newbie. I am currently in the uk and would love to preorder the 10 but I can only get the UK version but I would like the US version. Are there any significant drawbacks? Would most likely use it on TMobile once I relocate to the US. I have seen earlier posts on frequencies and bands but I was hoping on a plain English response? Mostly interested in LTE of course. Thanks!
Gotta find out if the UK version of the phone supports US network bands/frequencies to see if it'll work properly with the network you're interested in. Software wise should be the same. The HTC UK site lists #WL SKU(America) under supported networks but it also says, "Network bands in regions may be different, depending on the mobile operator and your location."
I'm sure someone in here knows whether you only get support for one region based on where you order from or if you get support for all regions listed on the spec page. Unclear to me. US page only lists US bands though.
I dont think the EU/ASIA models have the US LTE bands.
Sent from my SM-G935T using XDA-Developers mobile app
Yes the main difference is the LTE bands. The US version has different bands to the UK version. Generally the UK uses band 8 for LTE, which the US version does not have. You would still be able to use the phone for texts, calls and even 3G access, but, you would not get LTE. Let us know, what service provider you are with, we can then see if the phone is comparable or not for you.
Hi
I don't have the phone yet obviously. I am on three UK now but once we relocate to the US I will most likely be signing up to TMobile. I thought some of the frequencies are the same? Different bands but frequency seems the same in the UK and US?
But to be honest after looking into it might be best to pick it up in the us for the warranty and the Uh Oh insurance.
Thanks for the replies. Hope this question helps someone else.
From what I can see, Three supports band 3 for LTE. Looking at the US speck phone it says the following: 4G LTE (up to 450Mbps), FDD: Bands 1, 2, 3, 4, 5, 7, 12, 13, 17, 20, 28, 29, 30, Support Cat 9 LTE, download up to 450 Mbps, upload up to 50 Mbps, so in theory it should work for you both here and in the US. I would double check with Three that their network is definitely band 3.
Thanks Stephen
At the same time of posting here I had also emailed HTC support and they came back to me with a brief statement that it will work as the phone supports 'multiple frequencies'. This was not a highly technical reply but at least now I have it writing!
Your answer certainly puts my mind at ease and I have gone ahead and preordered!
Strangely I had no option to choose 32 or 64GB storage though and they took payment immediately rather than wait till shipping time. Does this mean it's on the way already?
Thanks again. Will revisit this post in three months time I suppose and jet you guys know!
I've been wondering about this, too, and I think the UK HTC 10 is not fully compatible with AT&T or T-Mobile networks in the US. From Droid-Life, the bands needed are:
AT&T LTE bands 2, 4, 12, 17
T-Mobile LTE bands 2, 4, 12
From Clove, the bands supported are:
FDD B1, 3, 5, 7, 8, 12, 20, 28, 32; TDD B38, 40, 41
As you can see, the UK version is missing bands 2 and 4, which are used by both US GSM carriers, and also 17, which is used by AT&T.
I've been looking at this because the UK HTC 10 is about the same price as the US one, but it comes with HD earbuds. Unfortunately, it looks like it's incompatible.
EDIT:
I also found HTC's international HTC 10 page, and it spells it out pretty clearly in the Network specs that the EMEA version of the HTC 10 is missing many bands from the American version If anyone has information to the contrary that would be great...
I have the International HTC 10 (m10H) and its working on AT&T LTE band 17. I haven't seen it connected to band 2 or 4 yet.
I'm using a UK version on Tmobile and it works fine the network.
My signal stays on 4g and I've only dropped to HSPA once, which is fine with me. Aside from that, text, calls, etc all work without issue.
If you're after the headphones, they're pretty nice though they're a bit bass heavy for my taste. They sound good though and the noise isolation is surprisingly good.
Hi
probably you can use con T-mo, but you can not use in AT/T. The asian version doesn´t work in any 4G in the US

OnePlus 3 - Sprint 3G and Service Bands

Hello, I have a OnePlus 3 and have Sprint. Not realizing the device only supports GSM out of the box i found this thread: http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
Here one person was able to enable band 20 on a OnePlus One. I was wondering if it is at all possible to enable bands 10 or 1 for Sprint 3G. Or better yet bands 25, 26, 41.
I was also wondering, if I were to attempt this is there a risk of ruining the phone?
I recall band 20 was unable to be activated on the OPO as the device simply was not provisioned with a radio for that band.
Modding will not overcome hardware deficiencies.
Is Sprint a CDMA carrier? OnePlus do not support CDMA at all as the US is the only significant country using that outdated technology.

would there be any way to enable wcdma 3g through sprint or should I sell the phone.

I do not think so.
First, I am assuming you have the international OPO. Go to willmyphonework.net and see for yourself; your phone is totally incompatible with Sprint. Even 2G bands are not available under its standard configuration.
At this stage you have two choices, return the phone for exchange/sell it or try and edit the hardware settings to make more bands available.
If you bought it new I would just return it rather than modifying the hardware setup.
If you want to tinker with it, you need to start here and also here and see will they unlock the bands you need.
Basically, follow the guides exactly and tick every radio band that appears in the programme and hopefully the bands for Sprint is among those available for your hardware.
I think I tried to activate band 20 4G and it did not seem to work. I have the international OPO.
The OP in the first link is a Chinese model, but the steps are the same.
To quote from the 2nd link I posted:
It will theoretically unlock:
GSM: DCS-1800/P-GSM/E-GSM/GSM-850/Railways-900/PCS-1900
WCDMA: Band I to XI
LTE: Band 1, 2, 3, 4, 5, 7, 8, 12, 13, 17, 19, 20, 21
PS: Even if they're theoretically enabled, some band cannot be used because of hardware limitation...

Even though all the above seem to be available to activate, some work, and some do not. [band 20 has a strikethrough, for example]

Updating Firmware & activating more LTE bands on Cricket Lumia 640 and Lumia 650

Greetings Everyone!!!
Had purchased the cricket lumia 640 and 650 in the US. Both are unlocked versions. But while roaming out of country I find that the LTE bands are not supported outside of the US. From the Cricket specifications and by going into the field test mode I see the following bands supported LTE Bands 2, 4, 5, 7, 12, 28.
Is there any way to activate the following LTE Bands on the phone : 3, 40, 41 as I believe these bands are definitely supported by the phone in other regions so I think it may be a firmware upgrade which could enable these bands?
Thanks in advance for your help
There is an option in wptweaker for that make all band H+ or 4G for more signals its what I do always ...
There is many weak signals in our home with this work signal are still weak but at the least I haven't any disconnection
@Ferrybigger - so does it allow us to enable more bands of LTE? Right now it shows me LTE Bands 2, 4, 5, 7, 12, 28 so does it allow us to enable more bands like 3, 40, 41.? Thanks for your answer
Yes there is a way. I enabled the bands on the 950 Lumia for AT&T (LTE: 1, 2, 3, 4, 5, 7, 12, 13, 20, 29, 30, 41) using its modemconfiguration.cab file on my 650.
https://forum.xda-developers.com/windows-10-mobile/controls-active-lte-bands-x50-phones-t3609630
You can probably piece together how to do it from this guide I did for enabling VoLTE on the 950XL and IDOL 4s...https://forum.xda-developers.com/windows-10-mobile/guide-enable-att-hd-voice-volte-t3632383
I cannot guarantee how the 650 will handle the bands but they show up under field test once applied correctly.
EDIT: Looks like you want 3, 40 and 41. The above info will get 3 and 40 only, but that is a start I suppose.
I will also add that the 640 is a gen device below the x50s. It is a bit different in how they hand nvi/modem settings. Like the 1520 or a couple other Nokia phones. You can use in part this guide (https://forums.windowscentral.com/w...-enable-more-lte-bands-t-1520-a-new-post.html) to possibly enable the same bands on the 640, which should be similar to enabling it on the 1520. I am not certain on the 640 though since I have never owned one.
@nate0 Thanks a lot. Will go through the guides and try to see if that works. Will provide an update soon
Sure thing.
EDIT: for the Lumia 650
-You need full filesystem access.
-You want a modemconfiguration.cab file from a phone that has the LTE bands needed.
-Backup your current modemconfiguration.cab file from :\PROGRAMS\CommonFiles\OEM\Public\MMO\Multivariant
-Replace the current modemconfiguration.cab file in that location with the new one.
-Run thor2.exe -mode uefiflash -ffufile <the path to your Lumia 650 ffu> -do_factory_reset -skip_flash
Make sure you use the skip_flash option. Otherwise you'll reflash your phone.
@nate0 looks complex Thanks a lot for the step by step guidance.
Would this work on an 830 by chance? I have 4 to mess with, 2 on W10M so it wouldnt really matter if i bricked one, but it would be nice to have LTE while on a phone call on T-Mobile instead of Edge.
@Talon Pro
For Nokia models you could use this thread to alter the bands using the nvi files https://forums.windowscentral.com/windows-10-mobile-how-guides/464924-guide-wip-enable-more-lte-bands-t-1520-a.html#post3703832
I hope this works for non lumia phones like the Elite x3
Im using t mobile and I also looking for ways to improve the connection strength and coverage. I've even turned on on roming to see if that works. Could unlocking these bands help?
It does not work the same on other OEM phones for changing the LTE bands. They also do not have the field test app for checking system settings and band locking...The modem configuration is not done the same from the OS on non-Lumia models.

Enabling LTE Bands from the LG Secret Menu?

I have a PM edition that has been cross flashed to a ULM. Someone pointed out that the ULM version doesn't officially have certain US bands like 12, which are very important for T-mobile/AT&T here. But the original PM version does have those.
I went into the service menu (*#546368#*710#) and found the bands listed under the field test mode and went and disabled everything other than B12. At first there was no service, but after a quick toggle of airplane mode, I'm connected to Band 12 (according to signal spy at least). I even did a speed test to make sure it was sending / receiving data. I was previously connected to Band 2 before doing this.
I'm not sure what this proves- is B12 only available because my hardware is the PM version? Or are the bands controlled by software? I have to admit, the service menu seems to offer all the possible bands this SoC is capable of, including B71 . That's interesting because I thought B71 is only on the T-mobile version and not available on the ULM or PM versions. Does fiddling with the service menu essentially let you enable whatever band you want on any edition of this handset?
I have a real ULM and connect to LTE 12 without issue. IIRC, your PM crossflashed to ULM will work on all T-Mobile LTE bands except 71. If you feel like experimenting, there were rumors that AWM firmware may enable band 71 although I don't know recall anyone specifically testing it.

I'm thoroughly confused now, I swapped to another "ULM" (also crossflashed from Sprint- the first had a physical defect that I returned and swapped for another), and didn't do anything to the service menu and STILL connected to the same bands according to software reporting. Bands that according to online resources, the ULM isn't supposed to support. Yet it does, and you say your real ULM does too. So obviously the spec sheets online are wrong and I have no idea what bands any of these handsets actually support or if doing anything in the service menu makes any difference at all.
Someone said another edition of this handset (european maybe?) had his menu showing a different set of bands available to select than mine, so I wonder if this is controlled via the firmware or the hardware (NVRAM values or whatever?). The service menu appears to just serve as a way to isolate bands available to test if certain ones work where you are. And on my PM turned ULM, band 71 is listed. I don't have 71 around me so I have no idea if this is real or not.
Wish there was more (accurate) information about there about how this works.
I'm on T-Mobile and usually connect to LTE 2, 12 or 66. Of those I'd say most of time 66. I've never seen a connection to 71, which I always figured meant that its not supported by the phone. If you are interested in trying to get 71, flash AWM and see what happens.
So it follows the firmware or it follows the hardware (nvram values)?
ALL g7's other than the g7+ are capable of the same bands. They are software enabled or disabled or even hidden.
If you can access ##data# from dialer and input the msl code to get to band priority then you can connect whichever you want.
If not the secret menu is needed to access the ones you need.
If the firmware did not include the band in secret menu then it has been disabled. At that point you need to access via a nvdata application like cdma workshop to enable them forcefully, but it will clear out after each restart since cdma workshops adds the band temporarily.
Well why do the bands on ulm stop at 40

The ULM version definitely does have Band 12.
How do I know? I followed this guide: https://mt-tech.fi/en/how-to-get-4g-supported-ca-combinations-from-your-android-phone/#LG_devices
I extracted the qmdl log and followed the steps to extract the actual supported bands as well as carrier aggregation combos right from the actual modem logs (which are 100% accurate, since LTE devices need to report this to the network every time they connect to it)
LG G7 ThinQ (US) (G710ULM) | 4G/5G Bands & Combos
4G & 5G Bands, Carrier Aggregation and Dual Connectivity Combinations for LG G7 ThinQ (US) (G710ULM)
cacombos.com
Here it is for the LG G7 ULM. Not only does it support Band 12, it also gets Band 17 and a wide variety of CA combos in that band.
