Do we have a way of Unlocking Lte bands yet? - OnePlus 3 Questions & Answers

Just curious because in all my excitement I failed to realize that the Oneplus 3 does not support Verizons band 13 I have the North American version BTW

i join in!
bought the phone while on vacation in the US. where i live, LTE mainly uses band 3 (1800) which is not supported by the US version.
only thought about it after i was home

Both the North American variant and the China variant share model number A3000, there's a high chance those two variants are the same piece of hardware. The China model is said to support LTE band 3.
You could try this out to enable all hardware supported bands. Please let us know the result.

Enabling bands on the OnePlus line of devices requires a patch to the NVRAM, one of which hasn't been made for the OP3 (and older patches cause bootloops). When enabling bands, the NVRAM resets on boot, reverting all changes. I've done some research and testing, and it seems that missing bands aren't the problem. It's provisioning. The OP3 fully supports most of the bands Verizon uses, but doesn't know how to switch between LTE and CDMA. You can force LTE with a few build.prop edits and changing some cellular settings, and it works blazingly fast - but, you can ONLY use LTE and nothing else. I'm still doing some more work, but a few people that know more about RIL than me have said they will begin looking for a solution around October. For now, just enable data roaming (which isn't actually roaming if you're in the US) and use 3G. I'm confident that we can get it working eventually.
Band 13 isn't some magical necessary band, it's just the first and therefore most common band. Yet my area doesn't even use it.

thanks for the reply.
i am actually currently living in Israel (so Verizon are quite far away )
the local networks all have LTE on band 3 (1800) which is not supported on my OP3.
i did manage to get 3g without doing anything, and following your bootloop comment, i will probably wait until October for someone with the know-how to generate a stable working solution.
thanks anyway!
BTW, while i was in the US (Oregon) i used T-Mobile and got LTE all day long with default settings on the same OP3 device.

Well, mine is China version and I mainly live in the US now. It would be a great deal if we exchanged our phones.
Anyway, I feel HSPA+ is fast enough for me, at least better than my wifi at home.

That I had no idea, Thanks for the information.
In fact the only band I need(more like Wind Mobile Canada need) is UMTS band 4, Wind does not have a LTE network yet.
I'm just trying to figure out if the China model supports UMTS band 4. If it does I could simply buy one here in China and bring it to Canada instead of spending 100 CAD more for the Canadian North American model.

Oops. Not used to having an international phone, forgot that not everybody is on Verizon . Anyways. Until someone can make an NVRAM patch, the only thing that might help are some build.prop edits. I'm actually currently searching for them, I'll post them when I find them.

So volte works fine for me but on LTE Discovery I only see my OnePlus 3 connecting to Band 4 and getting mediocre reception, and I'm pretty confident where I live there is band 12 (central Austin, Texas)
Anyone having a similar issue?

will editing the build.prop open up the locked LTE bands? or will it just allow me to force LTE on the currently available LTE bands for my device region?
more specifically, will this enable LTE band 3 even though the OP3 is the US version?
if so, i am willing to play along and if i get good LTE coverage at home and work, i don't mind it being LTE only.

I'm join too to the questions, like to take a part of this too, there is any news? Thanks

Also interested.. have only band 3 coverage and bought the OP3 in the US..
Thanks

As I see it now, I talk with few people and they all said that it can't be done

Yeah interested in knowing this as well since I can only really get the US version easily to New Zealand.
My provider only supports:
LTE (band 3) 1800 MHz
LTE (band 28) 700 MHz
RIP :/

It won't enable bands. Can't. It WILL force a connection to LTE on any supported bands in your area, though. I'm so sorry, but I'm currently in the process of finding the build.prop edits I mentioned, I had them on a thread on a different account that appears to have been deleted. The second I find them I'll post them.

So I'm having a hard time getting edits to actually work. I was on CM13 at the time and I'm currently on RR, but it might just be my location (on vacation). But for those who wanna try, here are the edits:
lteOnCdmaDevice=1
to.telephony.default_network=11
There were a few more concerning GSM and CDMA operator numbers, but those seem to have no effect. You might also have to fiddle around in the cellular data settings and change from Global to LTE.
One thing is for sure - these won't work on Oxygen OS. I can't get a lock on 4G on Oxygen no matter how hard I try.

thanks for your effort!
but that doesn't solve the issue, as the problem is not with connecting to LTE network but the LTE network being on an unsupported band.
forcing LTE will only leave my phone with no signal at all...
is there any way, instead of enabling locked bands, to change the region of the phone?
meaning, i don't mind losing the US bands if i can gain the EU bands.
so is there a way to completely change a OP3 from US version to EU version? so that no band unlocking needs to take place?

Joining the request. I have the same problem: missing band 3 on the US version.

Joining the request as well. I have de A3000 Chinese version and I need to enable Band 4 for Latin America

Joining the request, too. my country is covered by bands 3.
A3000

Yeah well I'm joining in.
Whoever makes a working NV/rmt/whatever patch for 64bit devices get a cookie from me. Or at least, find another way to prevent the device from resetting the NV edits we make. I got the North American OnePlus 3 and it's the one that doesn't support Band 3 (1800MHz) which my country's 4G connection runs at.
Rebooting resets whatever NV edits we make and even on CM it does that as well. I wouldn't mind staying on HSPAP but in a couple of years that might be just obsolete.
To any developer that's interested in doing this, I'm your guinea pig, just PM me and I can test anything for you.

Easy to repair speaker (speakerphone/music, not earpiece)?

I am looking to get a phone a bit nice than my HTC vivid. Someone at my local craigslist is selling the LG Nitro HD in "brand new condition except speaker doesnt work" with an extended batt + cover.
I can probably get it for about $140 or so. Best deal I'm finding on anything that will work with AT/T and tmobile.
So the question is, is it easy to repair the speaker? I see that once you take off the back you can see the speaker. Is it simple as pulling out the old one and putting in a new one, or is soldering and what not required? Thanks in advance
Just read that you can not use 3g/4g from Tmobile on unlocked AT&T LG Nitro HD = nevermind, not interested. It was such a sexy looking phone, too...
The speaker comes as part of an assembly and looks like this: http://dl.xda-developers.com/attach...840c00b004d404/50beaea0/1/0/1/9/3/6/7/4th.jpg . It's extremely easy to replace (only remove 3 screws under the battery cover).
You can see this guy remove it here: http://www.youtube.com/watch?feature=player_detailpage&v=5oPGrgCdOoA#t=41s

Yeah, almost no AT&T phones will work with T-Mobile 3G. For T-Mobile, I'd definitely get a Nexus 4.

I actually installed the custom rom Virtuous Inquisition on my HTC Vivid (AT&T and EVERYONE says it will not work) and I get 3g and sometimes HSPA on it. Was hoping maybe case was similar here but guess not
So sad because Nitro is a super sexy phone (I think at least)
Actually I'm wondering if it's because Tmobile has rolled out the new radios or whatever it is that makes some phones compatible in my area... I keep hearing about that... "Flipping the network" or whatever... Anyway to test that thoery? because that would mean many phones should be compatible, right?

The Vivid (and several other LTE devices on AT&T's network) support LTE on the AWS band, which is the same band that T-Mobile's 3G network runs on. Although nearly all of AT&T's LTE network is on the 700MHz band, they are beginning to roll out LTE on the AWS band as well. That means the Vivid has an antenna in it tuned for AWS. It's possible that internally it is wired such that it can also use 3G data on the same band (since it already has the antenna), but is "disabled" through software (since 3G on AWS is useless for AT&T's own newtork). A custom ROM might be able to override that.
I'm just guessing here though, so don't take this as fact.
However, if I am correct, the same method wouldn't work for the Nitro HD because the Nitro HD does not support AWS band for LTE. As far as I know it's the only LTE device on AT&T's network that supports 700MHz LTE but not AWS LTE.

I know everything there is to know about computers... But not a whole lot about phones at all lol. Taking your word on this (your use of terminology has me convinced) and assuming that it will not work, ever. Thanks
Why OP sees T-Mobile 3G on an AT&T phone is because TMo is refarming its 1900MHz spectrum and deploying [email protected] in some markets. This is mostly for iphone but many other phones also benefit from that, including P930 here.

[Q] Lenovo Z90-7 (VIBE SHOT) 4G UK HELP PLEASE?

Hi guys,
I have just bought this phone and flashed it with the latest firmware Android 5.1 as per the post on this forum. I am now very worried because my phone only seems to be connectiong to 2.4ghz network instead of 5ghz. Also I cannot get mobile data working.
What ROM/kernel did you flash? Many ROMs run 5.1.x

Hi I used this rom Z90a40_USR_S118_1505272046_Q2020131.4_ROW_qpst
which was mentioned here on the forum as the best for Android 5.1
Hey man, I've done some research and it seems your ROM/phone should support LGT(4G). I would highly suggest completely wiping your phone, reflash ROM/ Gasps/ kernel (if you have one) and see if the issue persists

The seller says I can send the item back for a full refund but unsure if he will give me a refund as I've changed the ROM to 5.1 The worst thing would be sending the device back to China
Okay, have you tried manually setting your APN? Fallow the steps below and findnthe APN settings online for your carrier, let me know what happens.
Many users have told me their 3G/4G LTE data network connection is broke after installing a custom ROM. *Well, in most of these cases, it can easily be fixed by manually setting the APN (Access Point Name). *This applies to any GSM networks such as*AT&T or T-Mobile. *For CDMA networks like Sprint or Verizon, they also use APNs but you don’t have to set them and should work out of the box.
Every carrier uses its own APN Settings to get its 3G/4G LTE network working on an Android smartphone or tablet device. *Now, these APN settings are usually “downloaded” automatically to your*phone*when you insert a SIM card. *BUT, there are times where the APN are not selected automatically OR when the APN settings are not downloaded.
In those instances, your 3G/4G LTE data will not work but that can easily be fixed.
Step 1. First, browse your Settings menu and find the “Access Point Names” menu. *This is usually under “Mobile Network Settings” or “More*mobile Networks or “Mobile Networks” under Settings menu depending on the Android device used.
Step 2. Once you are in the APN Settings menu, first thing you should check it that the APN is on the correct one. *If the correct APN is not checked (sometimes this happens), simply check ON the correct APN for your carrier. *That will make your 3G/4G LTE data working right away
tep 3. There are also times where the wrong APN is listed or there’s simply no APNs listed. *In these rare cases, you can simply add a new APN, hit the “+” button.
Step 4. For APN setting, the “Name” can be anything. *“APN” setting is the most important, usually you only have to fill this out for your phone to work.
For T-Mobile, you can set the “APN” to “fast.t-mobile.com”. *AT&T, you can set “APN” to “phone” or “pta”.
Now setting “APN” will get your data working but you still need to input additional settings to get your MMS working.
ep 5. You can usually Google APN settings for your carrier. *Whether you are in Thailand or in the U.S., simply Google for your APN settings like:
Google “t-mobile APN 4G LTE” for T-Mobile 4G LTE APN settings in the U.S.
Google “True Move APN 3g” for True Move 4G APN settings in Thailand.
Eventually, you should be able to find the full APN settings for your carrier whether you live in Hawaii or on North Pole.
Once you have the correct APN settings, simply input them into your APN settings on the phone
Step 7. Next, make sure to select the new APN Setting you have saved. *Within 5-30 seconds, your phone should start picking up 3G or 4G LTE signals and your data should be working again on the phone.

Hi guys,
I have just bought this phone and flashed it with the latest firmware Android 5.1 as per the post on this forum. I am now very worried because my phone only seems to be working on 3G. When I go into settings and network it only gives me the options to pick a 3G network. I did a lot of research before buying this phone and was assured it would work on 4G within the UK my old phone the Sony Xperia ZR worked on 4G fine. I do have the latest nano sim.
Here are the details of the Lenovo Z90-7 As per GSM Arena
Technology
GSM / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE 800 / 1800 / 2100 / 2600 - Lenovo Z90-7
And from my network operator's webpage I get the following info
4G from Tesco Mobile (o2) uses the following network frequencies:
800 MHz (0.8 GHz)
Am I having this problem as I flashed it with new firmware?
Click to expand...

I believe the phone doesn`t have the LTE 800 frequency.
Search other websites than gsm arena.
That`s why you don`t get 4G.
Hi Friends,
Thanks for the quick replies I really appreciate the help. In regards to the APN settings I've checked these and these seem to be correct.
So it *Should* work EE
Interesting, I was hoping the APN settings were the cause. I'm sorry you couldn't fix your issue. I'm sure you will have better luck with your next device.

Valter84 you are correct I spoke to the seller and he advised that there is a mistake on the listing the phone does not support the LTE 800Mhz frequency.
So it *Should* work in the UK on the network EE which uses Band 3 FDD LTE (1800mhz). I've tried an EE sim and it still does not work at all on 4G.

Hi, I have the same trouble as you , anyway I have not flashed my Z90-7 yet. My chinesse seller from Aliexpress claims , that this phone supports all usual LTE frequencies including 800 Mhz.
But I can use here in Czech republic at T mobile provider only 1800 Mhz which covers only Prague and Mlada Boleslav . Rest of our country covers LTE on 800 Mhz only.

This seems to be a worldwide problem outside China. It is nothing to do with APN settings, etc.
A company is selling this phone on Amazon USA and they have specifically mentioned 4G does not work in the USA.
I am based in the UK and 4G doesn't work. I have flashed the phone and have now android 5.1 installed on it, but until official EU version of this phone is released we will be stuck with 3G

Dear people, wake up, many Chinese markets are deceiving customers by providing them misleading information. LTE bands is one clear example. Chinese LTE bands are diferent and they just flash the device's ROM for multi-language and add Google Play to make it "international version" but it is not. DON'T BUY IT!
I double checked with this company minideal.net which i cannot recommend. The company confirmed full FDD LTE (4G) functionality on following frequency bands: 800/1800/2100/2600MHz. But my smartphone IS NOT WORKING on 800MHz in The Czech Republic because it is only 1800/2100/2600MHz in fact. Within the PayPal Dispute and Claim they completely turned around their statements concerning LTE bands.
Complete tests were made with my network operator provider to rull out other problems. You can easily check that in these comments and in some fair e-shops where they don't twist the truth.

This is correct, the phone doesn't work on 800MHz. However it should because Qualcom 615 supports 800MHz. the reason it doesn't work is because the modem is probably locked within the ROM. I am hoping once this phone is release european version then it should work at 800MHz.

Hi, i already have had the European version of Lenovo Vibe Shot (chinese name Lenovo Z90-7) in my hands. I purchased it recently to compare the Czech and the Chinese model concurrently. All worked perfectly well with the Czech model. The device connected to 800MHz LTE band (band 20) INSTANTLY after the Android system start. No setting necessary at all. It connected to 800MHz T-mobile band in the Czech Republic. While with the Chinese only 3G or less! Another LTE band (2100MHz perhaps) worked well - Vodafone Czech Republic. So LTE hardware is ok but 800MHz missing...
The test is here: youtube.com/watch?v=Mv5RoN_BYSc
No doubt i was intentionally deceived by the seller namely minideal.net; and many others customers are being deceived the same way!

This is amazing. I hope soon someone will release the european ROM, so I can update my chinese phone with european ROM. Do you think the Chinese phone will work on 800MHz with the European ROM?

Well, i consulted this with some mobile phone services earlier and they did not recommend updating the ROM like that. Your device can end up dead after it. The ROM must be perfectly tuned to the particular HW specification of your device to avoid the fatal consequences. It is quite risky... i was thinking the same way. I am disputing the seller via PayPal asking for partial refund to be able to re-sell the phone to someone who can do without 800MHz.
Also you cannot freely update the android system without loosing the multi-language and Google Play... So shopping mobile phones in China? NOT A GOOD EXPERIENCE FOR ME!

Ok, i understand your point. I was thinking the same way. Some mobile phone services would refuse to update the ROM like that though, because it can kill the mobile completely. And who will take the responsibility? The Chinese dishonest dealers should! Let us tell them, we don't like their deception and lies! They are playing the "we don't know" game, but they surely know enough about the differences between Chinese and non-Chinese LTE bands.
But yes, there should be a way to change the ROM the same way the distributors of the real European version of this phone do it. Only where shall we get that ROM and ROM update done? Because, as i have already experienced, the local (Czech) Lenovo representation has no interest in helping owners of Lenovo products purchased in China. How predicable...

A company is selling this phone on Amazon USA and they have specifically mentioned 4G does not work in the USA.
I am based in the UK and 4G doesn't work. I have flashed the phone and have now android 5.1 installed on it, but until official EU version of this phone is released we will be stuck with 3G

International Note 5 N920i on AT&T

Because I hate the idea of having a neutered AT&T Note 5, I bought an international variant (N920i). It appears the LTE bands are all compatible between the two. I will let everyone know how it turns out. If you already have experience with this, let me know.
EDIT: Yes, N920i works without any modification on AT&T
When does it arrive?
Thats very interesting.
from my SAMSUNG-SM-N920A using XDA Free mobile app
First half of this week hopefully!
Please keep us posted.
@alaskajoel Le us know if you have any signal issues.
The T Mobile S6 Edge on AT&T network gave me some issues. Calls would take 30 seconds to dial out and phone did not ring a bunch.

LTE showing up on the signal bar is a Domestic device visual. International versions Show E (edge) 3G, H+ (Faux G) and 4G for LTE.
If you are still unconvinced, my service mode presently shows I am on LTE Band 4. Download speeds at 40mbps this evening. No carrier aggregation unfortunately, but I also didn't have it on my Nexus 6 or the GS6.
I purchased the phone from a seller in Hong Kong via Ebay.
Awesome! Enjoy!
Yep, just like the International S6 G920I that supported AT&T LTE

I thought I'd give this thread a small bump as I'm about to pull the trigger on an international N920I as well.
My question stems from simply being new to importing phones and having to pay attention to bands. I have bene following this thread closely, and it seems as though the N920I performs well on the AT&T network, but is it the same as if I had bought one from AT&T? I ask only because it was just mentioned that this phone does not have Carrier Aggregation.
I'm not certain what carrier aggregation is (I looked it up on google but couldn't find much to answer my question). Does this mean that it will perform more slowly on US networks?
Also a final question, if anyone is willing to answer it. What is the region-locking situation on this phone? I have read mixed reports about people being stuck with phones that they cannot use because it was not activated with a compatible SIM, and some people that say they have had no problem. I don't want to drop $900 on this device and not be able to use it.

My data speeds and reception have been the same as my nexus 6 and girlfriend's GS6 (purchased from AT&T.) Carrier aggregation allows for next generation LTE, but I have yet to own a phone, AT&T branded or otherwise, that supports it in my area. It might just be that there is no support for it in my city, but I'll be in Chicago In a few weeks and will try to investigate it there.
I can't speak to the region locking. All I know is my phone was completely sealed and worked 100% right out of the box with only putting in an AT&T SIM card.

Thank you for the quick reply. I think I'll put in an order right now.
Samsung Pay
I'm glad to hear that the N920I works on AT&T on the LTE band. I considered getting the International version. However, there is something else that I am concerned about...and that is Samsung Pay that will be coming late September. I believe carriers have to allow (or configure) Samsung Pay to work. For example, Verizon may not be supporting it, at least that's what's traveling around the net. Also when I had the International Galaxy S3 on AT&T, Google Wallet didn't work, it only worked on AT&T versions at that time. Unfortunately, we won't know until Samsung Pay is available, but I wonder if it will work on the N920I?
Awesome news. can you please tell me if VOLTE works on AT&T or if you even had the option for HD calling? Settings should be found under data options.
Thanks in advance.
For those wondering, if you use an N920I on AT&T, there are a few things you should know.
1. Since this is an international model, the signal indicators are different than what we're used to seeing in the US. The SM-N920I shows the following indicators for mobile data:
E - This means you have a 2G/EDGE connection
3G - This means you have a UMTS connection with no HSPA
H+ - This means you have an HSPA+/Faux 4G connection
4G - This means you have an LTE connection
2. Phone calls will not work over LTE (VoLTE), and, by extension, HD Voice doesn't work either. The VoLTE and HD Voice components are proprietary software that is only built into the AT&T-specific ROM on the SM-N920A.
3. The phone DOES support carrier aggregation (otherwise known as LTE-Advanced), but not on AT&T's bands. Considering that the SM-N920I is intended for retail in Australia, New Zealand, and Singapore, the baseband firmware is tweaked to do carrier aggregation on band pairs that are common among carriers in that part of the world.
So, what does this all mean? If you want a phone that has support for all the bleeding-edge technologies on AT&T's network (VoLTE, HD Voice, LTE-A), then you have no other choice but to buy an AT&T-branded SM-N920A. However, if you want faster updates, no carrier bloat, no carrier branding, an unlockable bootloader, and don't mind sacrificing the whiz-bang stuff on the network side of things, then an SM-N920I will work just fine. Put your SIM card in, you'll get LTE data on all of AT&T's available bands, and you'll be able to make and receive calls over the HSPA+ network. You're just not going to have all the latest carrier-marketed bells and whistles that you'd get if you bought a proper AT&T-branded SM-N920A.
At this point, I *should* rant about how stupid it is that Samsung refuses to sell SIM-free, unlocked versions of their phones via US retail channels. That's what forces us to go through these 3rd party importers to get the international models that aren't really tweaked for the US carriers. Alas, I'm not going to go down that road, though. It's a tempest in a teapot.

Translation: On the 920i/c, the signal indicators follow the international standard of "4G" being "LTE", and not the AT&T/TMO marketing fiction of "4G" being what everyone else calls "3.5G".
As for the rest of your points, I have to wonder how well deployed VoLTE is on AT&T (and I don't think AT&T has even started LTE-A yet, have they?)
I live in a somewhat rural area, and I'm just thrilled I have LTE.. which beats the "no signal" I get with other carriers. I don't know that I've ever experienced VoLTE. (Then again, I can't remember the last time I actually had a voice conversation with my phone.)

Oh, but why not?! We really need some more activity in the AT&T Note5 section.

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

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.

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.
