Correct OP3 A3000CN Band Mode in US - OnePlus 3 Questions & Answers

Hey, I've struggled with adding US and EU bands on my A3000CN unit as I live in the US and need att or TMobile bands. My "band mode" selection in the so-called "hidden settings" shows differently than some CN OP3 units that I've read about. Simply a firmware difference?

VoLTE on Rogers (Canada)

I'm trying to figure out why VoLTE (Voice over LTE) doesn't appear to be working on the Nexus 5X on my carrier (Rogers Wireless in Canada). When I make a call, it drops down to HSPA+. While this still works for voice and data at the same time, it's less than ideal. I know Rogers supports VoLTE since the end of March of this year.
From the hidden *#*#4636#*#* menu, the option "TURN OFF VOLTE PROVISIONED FLAG" appears, but unlike the other options cannot be toggled. Additionally, the "Enhanced 4G LTE Mode" toggle does not appear under Wireless & Networks → More... → Cellular networks. I've attached screenshots of both screens.
Is this something that we will have to wait for a future update to enable? Currently on build MDB08I.

also curious to know about this... Do we know what band is used for VoLTE? I believe T-Mobile uses band 12 - (700MHz? or is 700 band 17?). Rogers rolled out that band a while ago (before VoLTE) presumably as a precursor for it.. maybe the secret lies here?
I cant test at the moment but I will when I get home.. Unless a zip can be made.
edit: 700mhz bands 12(700a),13(700c),17(700b) and 29(700d and 700e).

Band 12 is 700MHz (sometimes refereed to as 700 a, 699–716 UL 729–746 DL), this is used by T-Mobile. Rogers also has a 700MHz band, but it's Band 17 (sometimes referred to as 700 b c, 704–716 UL 734–746 DL). As I understand it, VoLTE is a prerequisite for enabling Band 12 on T-Mobile (along with E911 certification), but VoLTE should work for every LTE band (including Band 4, which is the dominant band used by Rogers/Telus/Bell).
I'm a little hesitant to flash the old radio, so please report back once you get a chance to try it!
I'm pretty sure Rogers on supports VoLTE on the latest apple products. Rogers sucks

From what I've researched, it supports VoLTE on the iPhone 6S/6S+, along with:
Rogers said:
The LG Vigor; the Samsung GS6, GS6 edge, GS6 edge+ and Note 5; and the LG G4 are all currently compatible. To see if your device is VoLTE-compatible, check the device specifications on rogers.com.

If you go to the device specifications on Rogers' website, nothing is written about VoLTE on any of the phones including the G4. However, on the blurb about the G4 when you search Android devices, it lists "Rogers VoLTE" as one of the features. Nothing on the GS6/edge/+/Note5 indicates they are compatible with VoLTE. LG Vigor is no longer offered.

so basically band 12 700a is useless to us on Rogers?

Right, since Rogers doesn't use it, it shouldn't matter to us.
I'm still not sure why the option doesn't exist (even grayed out) under "Cellular network settings" and why "TURN OFF VOLTE PROVISIONED FLAG" cannot be toggled. The option that exists for the Nexus 6 after the update to enable VoLTE was pushed (5.1) under "Cellular network settings" says "Enhanced 4G LTE Mode" as pictured in the attached screenshot.
It would be helpful if people who were on other networks besides Rogers (especially US providers) if they could post a screenshot of their "Cellular network settings" and tell us if "Enhanced 4G LTE Mode" is available. If people on other carriers have the option, then perhaps it is an issue of the device not recognizing that VoLTE is offered by Rogers?

According to other posts, the "TURN OFF VOLTE PROVISIONED FLAG" doesn't toggle but a reboot (or several) enables the Advanced 4G option to be enabled. I think both Verizon and T-Mo users have this option, just greyed out.
I don't get it either... we are all on the same firmware, I personally came from a G4 so VoLTE is active on my account but I think its a case of Rogers not allowing our "non supported" devices to use VoLTE. I'm calling tech support to see if they can help out..
edit: no luck.. they still have my device listed as a G4 and say everything is good on their end.
no amounts of reboots will help rogers.. but thank you..

Verizon has the enhanced 4g option.. only after some messing around I think.. http://forum.xda-developers.com/nexus-5x/help/verizon-voice-lte-t3231184
Yeah downgrading the radio did nothing for us. Since 700a is useless to us I'm flashing the new radio.

Thanks for the update. I'm still curious to find out if anyone has the "Enhanced 4G LTE Mode" option in their settings, and whether it's a matter of the carrier settings or not being enabled in the ROM. The fact that Verizon people are getting HD calls indicates it has to do with our carrier. I'm trying to get in touch with Rogers and see if they could possibly enable it, they're selling the 6P in their stores so maybe there's hope for our lovely device.

I didn't realise they were getting the 6p.. This might help us out a lot. Do you happen to know an eta?
Edit: just saw that Canadian carriers will be getting the 5X "soon". The word is end of October. Also noticed on rogers' page that there is no mention of VoLTE being a "feature" of the 6P. Here's to staying positive that it and the upcoming Rogers 5X will carry this "feature".. :fingers-crossed:

Last news that came out said they would start fulfilling preorders November 4th. It was delayed a couple times so it could be delayed again.
So the device is available now on rogers, but it is not included in the list when searching by VoLTE. Moto Nexus 6 is tho...
Weird thing is my account was set up with the G4, so VoLTE was set up on my account and according to rogers it still is but I am not able to get it to work with my 5x.

Yeah, even with 6.0.1 it still drops to 3G for calls, I'm not exactly stock so it could be an issue with how I flashed it but I doubt that is the case. It is still the case that "TURN OFF VOLTE PROVISIONED FLAG" cannot be toggled in the hidden dialer menu. Also there is still nothing under "Cellular network settings" that says "Enhanced 4G LTE Mode" like on the Nexus 6.
Since Rogers is only offering the 6P, I don't know if we'll ever see VoLTE for the 5X... but if they patch it in for the software for the 6P, they could theoretically add it in for the 5X too. So maybe there's still hope for a future update that will enable this. 6P still is not listed as a VoLTE device on the Rogers website, but now they are allowing you to search for devices that support VoLTE, which shows you all the usual suspects. So perhaps this feature is getting more prominent for Rogers.
Bell and Telus are offering the 5X directly, but neither carrier has launched VoLTE.
I have the same questions/issues with AT&T as well. My 5X will not expose the "Enhanced 4G LTE Mode" either. I have all the IMS based features turned on in the dialer menu. Of course you will need a SIM that is attached to a VoLTE account on the back end systems, and I have several of them. You have to be provisoned in the HSS and TAS as IMS capable. If I look at a registration event from the 5X it says its voice service is "CS Only" while my other VoLTE phones attach as both "LTE Voice" and "CS Voice".
I highly suspect the 5X is coded to not allow IMS/VoLTE for other than T-Mob and VZ, but why I don't know.

Which firmwares support VoLTE and WiFi calling on T-Mobile USA?

I've been toying with crossflashing a G710PM (Sprint) to various firmwares to find which ones support VoLTE and WiFi calling on T-Mobile USA. I started with the Sprint firmware (didn't seem to support either VoLTE or WiFi calling on TMUSA), then I crossflashed to the European Pie release (didn't seem to support either VoLTE or WiFi calling on TMUSA either), then the Verizon Pie release (this one at least had an option for WiFi calling, but it appeared to be disabled), and finally the G710ULM10j GFI release (VoLTE and WiFi calling working fine so far).
Does anyone know if any other firmwares besides the G710ULM can do VoLTE and WiFi calling on T-Mobile and can be crossflashed?
Does crossflashing actually "enable" certain Hardware related features? Including "enabling" all frequency bands for GSM on a currently CDMA firmware? I didn;t think this was possible. I think I read somewhere that Tmo WiFi Calling feature is disabled even on factory unlocked versions.

I cross flashed a G710PM (Sprint model) to G710ULM (Unlocked Google Fi firmware) and so far VoLTE and WiFi calling work fine. Network Cell Info reported Band 66 for one location I checked (which the G710PM model doesn't support but the ULM model does according to their respective spec sheets), but LTE Discovery reported it as Band 4. I'm not sure which is right, but it seems that a misreport as Band 4 would be more likely than a misreport as Band 66 since Band 66 is a superset of Band 4. So I think possibly it actually enables the other bands, but I can't say with 100% certainty.
Interestingly, the bands listed for enable / disable in the engineering menu don't match either the PM or ULM models.
Edit: Forgot to mention, ULM and PM both support both GSM and CDMA. I think maybe only difference in specs is which LTE bands are supported.
AH! I've been trying to get to the bottom of this whole "what bands enabled/disabled for what firmware/carrier" thing for weeks now. Even LG is vague in their answers. Yes, you are correct, I'm finding alot of discrepency in the actual bands supported for which version all over the place. No one has a difinitive spec sheet. Where is this "engineering menu" you speak of? I'm getting really frustrated finding answers. Ya, i think the reason WiFi Calling/VoLTE are working on the GFI firmware is because TMO is one of the carriers Google Fi uses, so it has to work. Otherwise, Google Fi users would be upset a key feature is disabled. I bet if you were using the USA firmware it would be disabled. The key to my whole frustration is, like you mentioned, "WHICH" bands are supported. I have ULM.BPT firmware and am concerned if I use it with GSM carrier not all bands will be "enabled". Is this correct?

Honestly, when I downloaded the firmware I don't think I even knew enough about the regions to know there was a difference between GFI and USA. In fact, how do I check which one is installed? I looked in the version information in Settings and there's nothing there to tell me the region. It must be tucked in there somewhere? Maybe the BPT, USA, and GFI firmwares are all the same? I just downloaded both the GFI and USA releases from the LG-Firmwares website and the files appear to be identical. Maybe BPT is identical too?
Regarding the bands, I honestly don't know if every model supports every band or what the deal is. I've been happy with my cross-flashed Sprint on T-Mobile thus far, but I certainly can't say for sure if there are hardware differences that make other models not work with every band (or even if mine works with every band it's supposed to or it just happens to work well enough for my area). Most people seem confident the T-Mobile model is different, at least, but I think it's more of a mystery regarding all the others.
You can get to the engineering menu by using the built-in dialer and typing *#546368#*710# Then under Field Test -> Modem Settings -> LTE Band Selection there's a list of selectable LTE bands. I suspect, though, that everyone's has the same list (1,2,3,4,5,7,8,12,13,17,20,25,28,29,30,38,40), because that's the list I got on mine and it doesn't match either the PM or ULM model. I'm curious if yours is any different.

Ha! Thats my point! What IS the difference? Why have 4 versions if there is no difference in the firmware? Notice the updates are same for GFI & USA, so what IS the difference? Only thing I can think of is the Auto Switching software for Fi. But AFAIK when u put Fi SIM in it tells you to download the special software for that feature. Then notice the BPT & BPS have same updates. So, again, what exactly IS the diff? Notice it also specifically lists the "Product Type" as either GSM or CDMA. This is why I'm getting so frustrated trying to get to the bottom of this once and for all. All 4 are listed as ULM versions. Does this mean the 2 CDMA (BPT&BPS) will NOT have all the GSM bands 'enabled'? And vice versa. I'm going by this BTW:
https://www.mylgphones.com/unlocked-lg-g7-thinq-lmg710ulm-firmware-update.html
Above in your list of bands: where is Band 66? thought that was a major TMO band? Ya, funny how the list doesn't match PM or ULM, huh? Again, my frustration. I bet you're not accessing all the TMO bands, only the ones shared with Sprint. (or the ones "enabled" by Sprint firmware) Like you said, maybe just lucky to live in area with good TMO coverage, so it never searches for other bands. U live in large populated area? Heard about the PM models being flashed to look like ULM? They seem to be sold on Ebay, Amazon, etc. Breed was company name. In my research, came across alot of buyers who were duped by this. Most saying they were having all sorts of connection/signal issues. Which proves just reflashing firmware doesn't "enable" more bands. I could be wrong. Your saying no problems at all. Also came across alot of VZN users saying problem with activating the ULM on their network. Which doesn't make sense either! Again, so frustrating getting to the bottom of this. I KNOW i read somewhere about the specifically TMO WiFi Calling being disabled almost everywhere except on TMO branded phones. (which would explain why it is working on your Fi firmware)

I'm just as confused as you are. As I mentioned, Network Cell Info says my phone was connected to band 66, which isn't available on the Sprint model. At the same time, B66 isn't listed in that menu. But then, B41 isn't listed in that menu, either, and that's supported to be supported on the Sprint model. So bands listed in that menu don't match any model that I'm aware of. Unfortunately the engineering menu code doesn't work on the Sprint firmware, so I wasn't able to check if the listed bands changed when I flashed over to ULM.
I've previously read the thread about the TM differences. I do know from looking at the FCC filing that the TM model has a different FCC certification number than ULM, so it's plausible that it is physically different from the others. However, PM shares a certification with VM and ULM, so I *think* they're the same hardware. That's why I'm wondering if *every* LG G7 lists the same bands in the engineering menu. Maybe that menu isn't actually listing all the supported bands for the specific phone?
In any case, the PM model supports bands 2, 4, 5, and 12, which is most of T-Mobile. Band 66 is just a superset of band 4, so most any B66 tower will offer B4 (though possibly at a reduced speed). So even if I don't get real B66, and instead just get the Sprint bands, that covers pretty much everything . Only thing missing is B71, which seems to be limited to TM model (which, interestingly, shares FCC certification with the Canadian model).

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)

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.

Unlock additional DR (5G) bands?

Hi all,
I'm wondering whether it is possible in some way to unlock additional NR bands on the S20. As far as I understand the Snapdragon 865 chipset, it comes as a fully-fledged 5G mobile platform which can be used in all countries and which supports all possible NR frequencies/bands.
So, it seems to me, that Samsung just locks off the majority of bands in the different models (for example, I got the G9810 and like to use it overall in Europe. However, Samsung only delivers the bands N1 and N78 but not e.g. N28).
Would be great if anybody could give me a hint about this.

I think there is no way to add more bands because these are defined to hardware. But i'm very interested about your model 4G Carrier Aggregation Combinations. These can get from log file: https://mt-tech.fi/en/how-to-get-4g...ons-from-your-android-phone/#Qualcomm_devices . Could you please share to me this BandInfo file? You can send this to https://cacombos.com/contribute
check out the Samsung Band Selection app on the Play Store. Supposedly, it can unlock hidden bands.
I looked at it but I'm unsure which bands are available to Sprint/ T Mobile in the St. Louis area. I set to Automatic. Playing it safe I guess .
Also when I switch to 5G it doen't show any bands. The S20 + is capable of more 5G bands I hear

Only can disable/enable bands what hardware support. If it doesn't you can't just randomly unlock bands.

What model Samsung S20+ you have? From modem logs you could export some data what your phone support: https://mt-tech.fi/en/how-to-get-4g...ions-from-your-android-phone/#Samsung_Devices

Lte Band mode

So I've traveled to USA and the network always on EDGE
I already searched then found that LTE band of the phone not supported in USA
But I found that I can select Band mode from specific code when I tried it said band mode locked
Can any one help me
What is your model? RMX2061 or RMX2063?
If it is RMX2061, it isn't compatible with US network
@kiro_koko
And, what do you mean by "Select Band Mode"? How do you do that?
