I have a droid maxx that I'm using for AT&T. For those of you who don't know, the droid maxx is supposed to be a verizon phone only. It is unlocked from the factory, but LTE does not work for AT&T or T-Mobile. Being that the maxx is essnetially just a moto x with a bigger battery, I was hoping someone could pull their radio from their phone and upload it so that I can flash it to see if it enables LTE.
There is much speculation that the maxx has the bands, but they are just diabled by verizon. I hope that flashing your guys' radio will unlock the bands. There was a similar method available to enable the Razr Maxx HD's to grab signal on AT&T. They use a motorola tool to flash the radio.
If anyone wants to help out a fellow motorola XDA member, let me know
For what it's worth, I have been told by someone I consider reliable at Moto that the AT&T version of the X does have the hardware to support the 1700/AWS band for T-Mobile, but that it isn't "software enabled" in the phone. So someone providing the radios for any of those carriers might be able to help a lot of us.

I think we'll also need a way to flash it, i.e. a custom recovery. I know Hashcode is working on SafeStrap, so hopefully that will be done soon and we can figure out if this works. I'm not sure if SS will allow access to the partition that holds the radio software, though. I strongly suspect it's just software blocked as well, so I think either flashing the radio or editing the NV values like they do for the last generation of DROIDs should open the AT&T models up to AWS. Or maybe I just really want that to be true.

Yes it would, but what I'm looking for specifically is to enable the LTE bands for AT&T on the verizon devices.

You wouldn't need to flash the radios through recovery. The radios can be changed with a motorola specific windows program called, CDMA WS 2.7. You boot the phone into BP Tools mode and then can modify the radio.

Hmm...didn't know that. I've flashed through recovery on other phones, I believe. I've never had to flash a full radio on a Motorola phone, though. On the Droid Pro, it was a flashed file that unlocked it, but it wasn't actually a radio. On the M, it was done through RadioComm. Anyway, regardless of the method, I hope it's possible.

It won't work. AT&T uses a different slice of the 700 band than Verizon as their primary LTE band. This means that they are using different radio hardware to pick up their LTE bands. They are incompatible.
AT&T also only uses AWS in a few sites here and there (not majorly rolled out in any capacity), so you're unlikely to get it with AWS as well in your city regardless. If you want LTE on AT&T, you need a Band 17 (soon to be Band 12 in the future) enabled phone. Band 13 may be 700 as well, but different slice, so incompatible. Flashing a T-Mobile radio might enable you to pick theirs up by unlocking the AWS LTE as Verizon has that disabled currently until they open up their AWS network using a software update.
Hope that clears things up and helps.
Yes I realize the networks are different, i don't doubt that. There is just speculation that the droid maxx is a world phone and has the bands there for almost everything but they are disabled. They do make a droid maxx Dev version so I can't see them making two different boards with different hardware for each.

If you don't believe me, check the FCC filings. They use the same boards, but there's more to that in making LTE work on a phone. As we found out with the Nexus 4, it may have the same hardware as the LTE compatible LG Optimus G, but unfortunately was missing the LTE radio hardware components, filters, amplifiers, etc (see Anandtech article). Motorola released several versions of the Moto X with the same boards, but different LTE radios (hence why we have an XT1053, XT1060, XT1058, etc).
Unfortunately, software cannot fix a missing hardware component. The Droid Maxx does not support Band 17 for AT&T, therefore, you are missing a hardware component and will not be able to get AT&T LTE regardless of how many radios you flash.
For further proof, look at the Razr HD forums. They only released one version (XT925) for internationally and we thought we could flash different radios to use abroad only to find out that different regions had different radio hardware (EVEN THOUGH they were all XT925 models). Motorola doesn't play when it comes to hardware.

Not trying to say you're wrong, but the Nexus 4 worked on LTE with the proper radio mods. Not sure if the signal levels were different than a phone that was LTE-capable out of the box, though.

The Nexus 4 only worked on Band 4 (AWS) LTE because it had the radio antenna, but none of the other parts (amplifier, filter, etc). The quality wasn't the same. Plus, people were using it on T-Mobile which has their entire LTE rollout on AWS.
For AT&T, per the original question, the Droid Maxx lacks the hardware for Band 17. For AWS, it is there and a radio mod could work, but you will only get it in like a handful of cities for AT&T as this is not their primary spectrum band.

Of course you would. Let's look at specifications (from the official site at http://www.motorola.com/us/shop-all-mobile-phones/Droid-Maxx/m-droid-maxx.html):
WCDMA 850/900/1900/2100
CDMA 800/1900
GSM 850/900/1800/1900
LTE Band 04/13
First, as a stipulation of the 700 Block auction, all Verizon phones have to be SIM unlocked. Therefore, that's why you can use your AT&T sim and get AT&T HSPA+ out of the box. It clearly says HSPA+ is supported in the specs (WCMDA 850/900/1900/2100). Why? AT&T uses 850 and 1900 for their HSPA+.
But AT&T LTE? Nope. Why? AT&T LTE uses Band 17 mostly, with Bands 2, 4, and 5 to supplement. Let's look back at the specs (LTE Band 04/13). Ouch, that's only 1 of AT&T supplementary LTE bands. Therefore again, you WILL NOT receive AT&T LTE on your Verizon Maxx unless you are in a Band 4 market (which there are a few and they're mostly small cities).
Flashing a radio will not fix the hardware issue of the lack of Band 17 support. Don't believe me? Try it. I've already tried with another Motorola phone in the past to spend lots of wasted time trying to exactly what you're trying.
But is the hardware missing or is it just a matter of software? Xperia T is software, hoping Motor X is the same way.
I'm interested in activating AWS on one of the unlocked models floating around EBay... The Puerto Rican ones.

Ok but this does nothing to tell us about the actual board in the droid maxx. Of course they aren't going to list the bands that the phone isn't capable right out of the box. The nexus 4 was listed as not having LTE even though it actually did. All I'm saying is that the bands may be there even though its stated that they're not. They may just be software locked. The only way to know for sure is by trying different radios to see if they are unlocked.

Looking at the Nexus 4, it was missing most of the LTE radio components. They just got lucky. Sloppy workmanship and design on LG's part. Motorola doesn't work like that. Check the FCC filings as they provide all the information about the device. The only thing disabled about the Droid Maxx is AWS LTE which is great for T-Mobile, not AT&T.
This'll be my last post on this one. Go ahead and try to flash radios. Repeat what many of us have tried before with other devices and find out the same thing. Motorola makes variants with custom hardware radios. This is why they get the best reception. They customize them to the carrier that wants it. So the hardware in variants is very specific and precise.
Good luck in your endeavor, but don't expect a miracle.
Any Updates?
I have a SIM unlocked AT&T Customized one, and when putting in my Truphone (TMo MVNO) sim, I am only getting EDGE. Now, Truphone does not use Tmo LTE yet - so I am only concerned with HSPA+...yet I am only getting EDGE. So, wondering if I am in a re-farmed area and would a modem re-flash support HSPA+....has anyone come across this?

If you are in a re-farmed area, you should get TMO HSPA+ out of the box, no radio flashing required. What is your area, if I may ask?

Finally someone who knows! So much misleading info on this issue. I bought the 1053 to avoid bloat, then the 1060 Dev Ed in hopes of somehow new rom or modem allowing LTE ( on basis radios were all firmware ). But _I believe you_ and will be returning the 1060 ( currently on ATT but would love maximum radios for traveling abroad ). But... would it perhaps be wiser to get the 1058, unlock the bootloader, flash a custom rom, and have clean-ish ATT + more world phone funness? I think I'm just going to stick w my 1053 but would prefer 2 more LTE bands for whatever may come up. Sense?

Hi all,
Im thinking of buying this phone but from what i have read there isnt much difference between the Atrix and the Atrix 4g.
How will I be able to tell which is which? specs are almost the same.
Should add that I am buying used. Also, I am in the UK.
Look forward to your replies!
They are the same phone!
I'm also in the UK, really like my atrix, but coming from a modded android to a locked phone is a bit difficult...

your sure? i read somewhere that the first atrix has 5mp cam which has been upped to 8mp in the new version.
Maybe im mistaken.
Yes ive heard about Moto not playing nice with rooting!
It is the Atrix 4g and the Atrix 2. And the Atrix 4g has a 5 MP camera and the Atrix 2 has a 8 MP camera. The most noticeable thing I saw in the looks of the 2 phones was the Atrix 4g has the speaker on the back at the bottom and the Atrix 2 has the speaker on the front at the top.

yeah that's right... looking at the specs on motorola website, seems that's the only difference!
cool, now i know what to look out for!!!
atrix(4g) is not a locked phone, is it? If you follow the guide, you can unlock the bootloader and flash different ROMs on it.
Another difference between atrix(4g) and atrix 2 is the fingerprint scanner. atrix 2 doesn't have it.
Since you are in the UK you will probably want the "Motorola Atrix" since it has the 900MHz UMTS band needed for some UK carriers like Vodafone and O2.
The "Motorola Atrix 4G" is the title used for the Atrix line that is used in North America for carriers like AT&T and Bell.
Look at these two links and you will see that the main difference is the bands used for their 3G networks. AT&T and Bell use 850/1900 and Vodafone and O2 use 900/2100.
http://www.gsmarena.com/motorola_atrix-3709.php
http://www.gsmarena.com/motorola_atrix_4g-3708.php
I could be wrong but this is what I can gather from your question. Also, you might be able to use the "4G" branded one because it still uses the 2100MHz band (if unlocked) but you might experience reduced coverage (slower speeds).
The difference in cameras is between the Atrix(4G) and Atrix 2.
http://www.gsmarena.com/motorola_atrix_2-4199.php
Which also does not use the 900MHz band.
EDIT: I would also like to point out that they do all use the same "Quad-band GSM" but that is for the 2G(EDGE) network, and not 3G(UMTS/HSPA)

Some suggested the only difference between atrix and atrix 4g is the firmware. But I don't know how true it is.
I have a Bell (canadian) atrix 4G, and I am currently in UK on O2. Is there any way to tell if I can use UMTS900 or not?
If there is a way to tell, and I manage to connect to UMTS900, then I will say there is no difference between atrix and atrix4G.
Right, an unlocked Bell/AT&T Atrix will work on almost all of the UK networks but it will be restricted to the 2100MHz band for 3G(HSPA) or quad-band GSM for 2G(EDGE).
You don't need to try "to tell" if your Bell Atrix is using the 900MHz band for 3G(UMTS/HSPA) because it cannot. It's in the specs, it just doesn't have the capability.
http://www.bell.ca/Mobility/Products/Motorola_Atrix_4G/Specifications.tab
Just to clarify, I'm not saying you can't use an unlocked AT&T/Bell Atrix in the UK, all I'm saying is it will not be able to use the 900MHz band for 3G. It will, however, be able to use it on EDGE/2G. I'm fairly certain it's a hardware thing.

People seems to be either pretty certain it is only a firmware difference, or pretty certain it is a hardware difference. But no one can confirm which one is correct...
I do agree, based on the spec from motorola, US/CA atrix doesn't support UMTS900.

Its annoying me because if its just a software limitation, what is there to stop us from giving it 900mhz umts support? The "workaround" just needs discovering by a developer (I've been mooching around, but i'm not dev!)
O2 UK has UMTS on 900MHz now, and one local to me so I want to use it without replacing it for a UK atrix lol.
What we need is an international/uk user to be brave and strip their phone down and find out for us!
My gut feeling is its something in the kernel/drivers/boot loader provided for the AT&T Atrix. On samsungs there is a secret menu for turning bands on and off.. but none of those codes will work on the Atrix of course (even the generic test ones built into android don't work!)
If you know anywhere close to London where o2 has UMTS900 coverage, but no UMTS2100 coverage, then I will try it out.
If I can get 3G at that location, then my Bell Atrix with UK baseband works with UMTS900. If not, then it is more than likely to be hardware.

If you can come down to Solent Business Park/Whiteley you'll have it there on 900mhz. They were digging up the road a few weeks ago right by the mast (which is pretty much line of sight with my office), and I took my Nokia N900 (on GiffGaff as its a spare!) which supports UMTS 900 and it had full 3G signal (atrix had full 2g), which it could never get before. The nearest 2100mhz mast is like 2 miles away. The atrix will pick the 2100 mast up rarely down there, and when it does, it has 1 bar if that.
I tried a few different base bands while at work, none seem to provide positive results on my AT&T Atrix.
When it comes to the differences of the Atrix and the Atrix 4G, it is the 900MHz UMTS band. The Intl version has it but the AT&T/Bell version does not.
While the OP (@jman316) was looking for the differences between these two versions, you seem to be trying to figure out how to access that band on the AT&T version, which is not possible.
GSM and UMTS are not compatible. UMTS is an evolution of GSM but they are not the same. So, going back to your dilemma, you have stated in your other thread that you currently have an AT&T version. Based on that, you cannot use the 900MHz band on 3G/UMTS/HSPA. Only 2G/GSM/EDGE.

I apologize if I seem derisive on the matter, I just feel that the facts are right there.

I'm very aware of the differences in the technology. I don't know where your comparison of GSM/UMTS and the links relevant here. Its a quad band gsm and quad band UTMS/WCDMA/3G phone with one band disabled be it through a hardware modification to the chip or by software.
What we are trying to drill down to is this:
1. Is it the same cellular modem chip used in both AT&T/Bell and the international versions?
If yes then,
2. Why is it not possible to enable the disabled band?
Has anyone really done any research into either of these? No. If had a spare pool of money I'd buy a UK phone, and strip it down, and prove once and for all what difference there is, and we could then say, oh so the chips are different models so that explains that or go, oh its the same chip/part number, lets hack the software a bit.

I have done a lot of research into the matter and from what I have gathered the chips/modules responsible for the compatible frequencies can be tailored to specs according to the customer's (AT&T) requests. Which, from my understanding, would be a hardware issue. So, even if they have the same chip, it wouldn't matter, since AT&T can have it custom made to just use the frequencies they approve. Which actually sounds a lot like something AT&T would do, given their track record.
I also found this thread where others are pretty certain it is not possible:

I'm very aware of the differences in the technology. I don't know where your comparison of GSM/UMTS and the links relevant here. Its a quad band gsm and quad band UTMS/WCDMA/3G phone with one band disabled be it through a hardware modification to the chip or by software.
What we are trying to drill down to is this:
1. Is it the same cellular modem chip used in both AT&T/Bell and the international versions?
If yes then,
2. Why is it not possible to enable the disabled band?
Has anyone really done any research into either of these? No. If had a spare pool of money I'd buy a UK phone, and strip it down, and prove once and for all what difference there is, and we could then say, oh so the chips are different models so that explains that or go, oh its the same chip/part number, lets hack the software a bit.

Ok this is all confusing now !
Will i be able to get 3g speeds in the Uk with the Atrix or is it limited to 2G!?
OK, we all know about Verizon using lower spectrum and AT&T using upper spectrum of 700MHZ but i could never understand how HARDWARE WISE they can make a radio that would only support such a thing, I am under impression that it is the software optimized for using either upper or lower spectrum and if block the other half. I just read how flashing correct radio enabled AT&T GALAXY NOTE to be used on t-mobile, i am not an expert nor i have resources, but has anyone attempted to flash verizon radio on at&t phone or vice versa and see if phone is actually capable of running on both networks? Please explain me if there is any flow in my understanding or is it actually feasible? would be great to break monopoly of at&t and Verizon over their LTE phones even though they utilize same 700MHZ band.

Certain chipsets with an integrated radio/modem support multiple bands. Like you said, in the case of the Note, XDA devs were able to flash a different modem that told the radio to tune to a different frequency that it supported. Same with the Skyrocket, and, if the T-Mobile SII had an LTE mode, that would have worked too. But not all chipsets can do multiple frequencies on one chip.
Well you'll have a problem of dealing with a CDMA phone trying to run on a GSM network primarily. I think Verizon's system has to verify you're on their primary CDMA network then allow you to connect to their LTE network. Where as an AT&T phone would just connect you to their GSM and then it bumps up to LTE. My speculation is that if you connect a Verizon World Phone with LTE on AT&T with the correct radio it MIGHT work. But it won't work the other way around as AT&T's phones don't have CDMA (which is used to verify and connect you to the LTE network)

You will never get a CDMA phone to work on a GSM network or vice versa (aside from global CDMA phones with SIM slots for GSM roaming). LTE phones on Verizon use a their own authentication that's separate from their CDMA-only 3G phones. With the LTE phones, there is no ESN/MEID associated with the device; it's the SIM that is authenticated and then the phone attached to it can use it to transmit and receive data, texts, and calls.
But that's besides the fact; CDMA and GSM are more than just frequencies; they're two different methods on how a phone communicates with towers. CDMA is Code Division Multiple Access, and GSM is based off of TDMA, which is Time Divided Multiple Access. It's kind of like saying, because two people are Chinese, they will both speak one dialect, which in fact there are two; Mandarin (GSM) and Cantonese (CDMA) which are similar but different.

some CDMA+LTE devices can be used with other carriers even with the different authentication, carriers that barely have 1X cdma coverage. the conversion of the MEID to pESN is done with a different method that is of course if the DEC MEID can be retrieved, not the HEX MEID.

Hardware wise it's damn easy to make a radio that doesn't support the upper/lower part of the band - just use a narrower frontend filter.
In fact, doing the opposite is hard - having wideband support without compromising the performance of your bands of primary interest is extremely difficult. Filtering out the "don't care" part of the 700 MHz band can improve RF performance in the "do care" part.

No, they didn't do anything to tune a different frequency. AT&T also uses AWS1700 for LTE - all they did was change modulation mode for an already supported band.

not sure about LTE
I see thread being carried away in different direction, I understand how it used to be completely ESN based, but trust me on new LTE phones it doesnt matter, i have popped sim card into many lte devices without registering with verizon what so ever, Also both at&t and verizon phones have hardware radio built in that supports 700MHZ so that is out of question as well, Hence I would like to draw attention of everyone specially DEV's, to target the real question, is it software based solution where they have tuned radio only to support perticular upper or lower band making them carrier specific? and if so flashing verizon radio on at&t phone or at&t radio on verizon phone make it compatible with each other? IF ANYONE OUT THERE WITH RESOURCES AND knowledge of radios can try this theory, it would open infinite gates of new possibilities ( AND GIVE US ALL AN OPPORTUNITY TO SCALE UP OUR LOVE-HATE RELATIONSHIP WITH ATT-VERIZON BASTARD ).
p.s. I appreciate sharing your concerns/understanding anyways, not trying to underscore your comments, just trying to get things moving in right direction.
Thanks, its kind of answer I was looking for to verify my doubt on whether it would be possible by software tweak to enable phones work on other networks, however my speculation is that there is a huge probability that some MODELS did not bother making this changes (e.g. motorola since they do not produce phones for at&t anyways or quite oppositely HTC which makes LTE phone for both att & verizon) and simply had software tweaks in place to avoid phones on other networks, IF SO it should be as simple of radio files swap as what other guy did to samsung tab. Please correct me if i am still wrong.

Samsung tab? Are you talking about the AT&T Galaxy Note? In that case, that was changing modulation modes in the same band. (AT&T also uses the 1700 MHz AWS band for LTE. So it's easy to just change that over to HSPA+ for T-Mo compatibility.)
I would not be surprised if Moto has narrower frontent filters, that may be part of the secret to their supposedly superior radio performance. (Rejecting unnecessary bands can greatly improve reception of the bands you care about.)
Great news this morning for whoever was holding out on buying the Moto X (2014) Pure Edition due to the LTE coverage. Motorola has said that they will soon be enabling LTE 3, 5, and 7 on the Pure Edition via an OTA update!
http://www.androidcentral.com/moto-x-pure-edition-xt1095-may-soon-get-more-lte-bands
Effectively, both XT1095 and XT1097 will support the same LTE bands after this update rolls out.

Huh? Verizon phones are factory unlocked and work on CDMA and GSM, compare that to what you get on T-Mobile, Sprint, or AT&T and Verizon has the best phones for phone junkies. Now unlocked bootloaders, I'll agree Verizon sucks with that.
Band 13 is only supported on the VZW edition Moto X (xt1096) and is one of their primary LTE bands. So yes the Pure Edition, or even regular AT&T edition for that matter, Moto X will work on the VZW network you are limiting your connectivity significantly.

Factory unlocked, really? So I could wait and pick up a Droid Turbo and use it on T-mobile? Hmmm, may have to research this. Although, the extra bloatware would probably keep me away.
But, back on-topic...
This certainly makes the Pure a much more useful phone. It still needs Band 12 (T-mobile owns Band 12 in 2/3 of my county) to serve the US providers that it is intended for, but this is definitely a good step in the right direction.
Awesome this will enable LTE in Euro for most people. This makes the new Moto X way more versatile than the old Moto X which contains only:[2/4/17] ... basically i can buy a moto x for any of my European friends

Well we can't say with 100% certainty since it's not out yet, but all other Verizon LTE phones are factory unlocked and can be used on other carriers. I've used my Verizon Note 2, LG G2, and LG G3 on T-Mobile. The only issues you would run into would be an "unknown SIM" in the status bar, and you may need to add APN entries. If you root though, you can easily fix both of these issues.
Actually itd be wayyyy better if they dropped band 5 and just included 20 ... 800mhz LTE is essential for non rural cities in Europe.
This discussion has already been started in this XDA thread.

Because this was previously reported here thread closed
I can't find any definitive answers on this. All I know is the minimum is 25, 26 and 41 but it'd be nice to know the full list. I travel internationally and without other LTE bands like band 7, it makes it tough to use it anywhere outside the US.
EDIT: Someone answered this question in another thread but it would be good to get screenshots to verify this.

LTE Bands: 2 / 4 / 5 / 7 / 12 / 13 / 25 / 26 / 41
I've heard that the FCC filings show that the Sprint variant is not capable (tested or approved) for GSM or WCDMA, which is kind of disappointing since I travel a lot in Canada. Any confirmation on this?

This list of bands is a little better than both the Sprint variants of the LG G5 and Samsung Galaxy S7. If this phone can be unlocked, you at least have a way to go abroad and use LTE connections in much of Europe and elsewhere. Band 7 is the most common band in the world from what I understand.
I'm curious about this comment about GSM and WCDMA. Hopefully someone can verify this one way or another.

If you plan to travel outside the US during most of this time, your best options are to sell your HTC 10 and get one of the few unlocked flagship phones on Sprint's networks, assuming you want to stay with Sprint.
Here are your options:
Google Pixel
Samsung Galaxy S7 SM-930U
Samsung Galaxy S7 SM-935U
Nexus 6P or 5X
Motorola X Pure Edition
Apple iPhone
Here's a full list as of February 2017 of radio unlocked phones compatible with Sprint.
There are other unlocked phones that are not compatible with Sprint because CDMA and LTE bands are crippled or missing.

Thanks for the response. The thing is I'm not on Sprint and have no desire to be. I won't be in the states long. I bought the phone thinking that like most, it could be unlocked and used as needed wherever I travel to. I knew it wasn't unlocked but figured I could do it myself. Well, I've tried a number of times, and keep having an issue with the radio. Can you explain what you mean by bands being crippled? What I'm trying to find out now is whether it's possible for me to get this HTC10 completely unlocked. I think I've done everything right but maybe not. I'm kinda desperate at this point. I love this phone. And if I have to I'll return it and grab another that can be unlocked but I just have a hard time believing that the phone can't be unlocked. It's a strange concept for me. Any help or info would be appreciated.

First, go go Google and look up what LTE bands are.
Crippled LTE bands = the hardware inside the phone will not allow certain LTE bands to work unless physically altered. It doesn't matter which ROM you install, you will not unlock all the LTE bands without physical alteration. https://www.quora.com/Does-installing-different-rom-change-LTE-band-frequency
So no, HTC 10 will never be completely unlocked. Look at the list above and buy one of those phones if you want a completely unlocked phone.

I'm not sure I fully understand. Yes, I know that different chips have different bands that they work with. So, what you're saying is the Sprint HTC10 variant uses either a different chip or has some sort of other hardware configuration that is incompatible with GSM and the wider LTE bands and that no matter what I do with this phone I'll never have a truly unlocked phone? That's what I have understood, so my best option is to send it back. Ok, I get that. But I have read across tons of forums and threads of people who unlocked their Sprint 10s and are able to use them on other non-cdma carriers. So, how does that work? Are all the Sprint 10s the same or are some more limited than others? Are you essentially saying that i would have to get an unlocked/dev edition of the htc10 to be able to use GSM in other countries?
Sorry if i'm asking stupid questions here, I'm just trying to fully understand this. Thanks again for helping me out on this.
If anyone reading this knows better, please feel free to correct me.
This is my understanding of LTE bands and CDMA/GSM radios.
Phones like HTC 10, which are locked, include hardware that are built for specific usages. Prior to HTC 10, HTC phones built for Sprint's CDMA radio were specifically built to lock out GSM radio signals and most other LTE bands using the hardware. This means you'd have to open the physical device and modify the wiring inside the phone in order to allow other signals to work.
As of HTC 10, the locks are supposedly now just software based but I haven't seen proof of that. What this essentially means is that you should be able to unlock the bootloader and flash new Roms that could allow the GSM radio to work universally. However, lots of people are having issues with it. Here's one story of someone who was mostly successful but still had issues:
https://forum.xda-developers.com/showpost.php?p=68960210&postcount=47
Read through the thread above and you'll see a lot of people having issues trying to fully unlock the radios and LTE bands for this phone.
If you ultimately don't want to be on Sprint anyway, I think you really should consider getting something already unlocked that can universally work anywhere. And lots of interesting non-Sprint compatible phones like OnePlus 3t (among the others on the lists I provided) are already unlocked and have a lot of good capabilities and would work great anywhere. The Pixel is one of the best devices out there and the camera is amazing from what most people say.
So I think your options are limited and I'd highly suggest you consider getting a Pixel or something else already unlocked.

They are software based. I have unlocked AT&T bands on my Sprint variant, 2 actually , and they worked perfectly fine. I would show you proof but I am back on T-Mobile which the Sprint HTC 10 already has LTE support for by default.

See my other reply.
So I've been looking through the V10 Android Development threads and wondering what it's been like on XDA with the V10 in terms of Dev support/ROMs/ etc. I've asked over there for feedback. Doesn't look like there's been much interest in the V10 phone from Devs? Is there a reason why? Locked bootloader? No "sources" released? Is there a CM ROM available anywhere?
Reason I ask is because I'm seriously considering getting a V20 which looks like a great phone and I've always had Nexus phones in the past. Currently rocking a Nexus 5 which I still love. The V20 looks to me almost like a larger more modern and advanced Nexus 5 (both made by LG). The G5 I saw in a phone shop and it really didn't appeal to me (build quality seemed poor). What's the likelihood the V20 will get decent Dev support? Is there anything that will make it more likely?
What specifically was wrong with the G5 build? My wife has the phone and we both think its pretty nice. At least as good as the Galaxy it replaced and probably a bit nicer.
I'm also interested in your original question. How much support will this phone get and will the boat loader enforce secure boot?

v10 was abandoned in short order after the bootlooping SNAFU.
This phone is starting life too expensive, unique snowflake hardware SKUs for every US carrier, And more than likely a locked bootloader (hopefully it can be unlocked). All those combined are a development death sentence. Assume no development, and be happy if there is any. Combined they make people who can develop firmware not even want to bother.
Remember the v20 has been on sale in Korea for a month now. How many buyers/users even post on XDA about it? Basically none AFAIK. There should already be a development charge, and maybe a root worked out or at least actively being tested. And there isn't any, not that has been made public.
lol dude we get it. every post of yours is the phone is too expensive and there's carrier versions of it... like every. other. phone. if you're so upset by price and carrier versions, why are you looming around these forums? go buy a 300 dollar phone and stop trying to sell everyone else on your opinion.

Considering there is an unlocked US model that seems will work for all carriers, I would think that would be the one that gets development and is quite conducive to it.
No development is getting slowed down because a phone is $800. That's the new norm if you want this high quality of a phone. Pixel will get tons of development, Note 7 was actually going really well despite the $864 price, and many others will too. The fact that it's LG and people overlook the brand continually will be the primary reason for lack of development, if that's the case.

Say what?
The unlocked version WILL NOT WORK on Sprint at all (the model # and IMEI range will be completely wrong to pass their whitelist)...and unless you have an already active SIM, your new VZW SIM will not activate as the model number is wrong and your account will show "unauthorised device". This of course sets aside the problems of radio bands that are missing or wrong for your specific carrier. So at best you'll have poor service if any depending on where you are and the tower deployments in the areas you travel. Also we don't know how updates will be handled on the unlocked device--take for example recent Nexus devices that got carrier fed updates rather than direct from Google (although that at least was an option if you ADB'd factory images) Every carrier is a unique SKU with unique firmware. You may never get updates even from LG (it is a serious possibility and risk).
I hope you have lots of cash hoarded when your $800 gamble, that it will work on all carriers, screws you over
The ZTE Axon 7 could be a much better device with much more development potential that is 50% the frickin price. "$800 the new normal" indeed. Buy an iPhone 7 for less cash, not an iPhone wannabe with less long-range OS support and let's be honest worse standby battery life. Because yea let's be honest, in 12-18 months LG will quit updating the device while in 3 years the iPhone7 will probably still be getting OS updates.

lol dude we get it. every post of yours is the phone is too expensive and there's carrier versions of it... like every. other. phone. if you're so upset by price and carrier versions, why are you looming around these forums? go buy a 300 dollar phone and stop trying to sell everyone else on your opinion.

Because folks ask questions...and get tremendously wrong answers. Like "the unlocked version that will work on all carriers". Echo chambers benefit no one. Until you see and know what having a unified hardware platform (like Nexus) does to accelerate development you don't get how screwed over you are by unique snowflake SKUs.
I too was excited for the v20, but LG fumbled the ball. in 3 months when the price comes down from the early-adopter surcharge (hopefully) I'll think about getting one. Depending on what I see.

Say what?
The unlocked version WILL NOT WORK on Sprint at all (the model # and IMEI range will be completely wrong to pass their whitelist)...and unless you have an already active SIM, your new VZW SIM will not activate as the model number is wrong and your account will show "unauthorised device". This of course sets aside the problems of radio bands that are missing or wrong for your specific carrier. So at best you'll have poor service if any depending on where you are and the tower deployments in the areas you travel. Also we don't know how updates will be handled on the unlocked device--take for example recent Nexus devices that got carrier fed updates rather than direct from Google (although that at least was an option if you ADB'd factory images) Every carrier is a unique SKU with unique firmware. You may never get updates even from LG (it is a serious possibility and risk).
I hope you have lots of cash hoarded when your $800 gamble, that it will work on all carriers, screws you over
The ZTE Axon 7 could be a much better device with much more development potential that is 50% the frickin price. "$800 the new normal" indeed.

Um, the unlocked version has all the Verizon bands and is completely compatible with all carriers from everything I have read.
The iPhone 7 is not a valid comparison at all. Different type of phone. iPhone 7+ model with more than 32GB of storage... That'll set you back over $800, like these other phones.
You're clearly an Apple lover so I'm not going to bother continuing to argue. LG V20 >>>>>> iPhone 7 that it's absurd to even compare, for me. I'd be really unhappy with that iPhone because it still lacks most qualities I desire in a phone. To each their own.

Then you clearly need to read more, not repeat flat out wrong info. The unlocked version is missing IIRC 1 Verizon CDMA 3G band (of 3), it is missing IIRC at least 1 WCDMA bands (out of 2 or 3), and it is missing IIRC 2+ LTE bands (Of 6 or 7 OTTOMH). The FCC filings showing that are available online. The same way that the unlocked version is similarly missing Spring CDMA/WCDMA/LTE bands. The radio support IS NOT THE SAME between VS995 and US996 and S997. It is NOT "completely compatible"-it is only sort of compatible....presuming it gets past carrier whitelisting of the IMEI and model number which on Sprint it 100% WILL NOT DO, and on Verizon it probably will presuming you already have a working SIM....then you have other problems to worry about (radio band support and updates).

I'm not an Apple lover at all. I'm fed up with Android OEM shortsighted foolishness.
The unlocked version also doesn't have AT&T's bands 29 & 30 and T-Mobile's Band 66. Personally, I plan to get the AT&T V20. I don't mind the (expected) lack of updates so much as long the current version doesn't have glaring bugs. For AT&T you also need a branded device for VoLTE.
I currently have the Nexus 5 and Google left it with major bugs for a few months (one of them was broken car Bluetooth). So my experience with Google wasn't that great. The Pixel devices look like bad iPhone and Galaxy copies.

Interesting. I'll look into it more.
I honestly don't care about development anyway - I left my Note 5 alone and loved it. I'm planning to do the same with the V20, but I do hope there is some development eventually just for fun.

The development is what I find cool. It is why I keep ending up being a tester for ROM teams (did it on Note 2, and still on Nexus 6)....but Android generally is getting really f'ing annoying on some of this crap. SafetyNet for example isn't just a framework for AndroidPay and stopping you from using your phone from paying for a burger due to Xposed, corporate email servers are now using it....so if you modify your firmware in any unauthorised way your employer may well not let your phone talk to your work email servers anymore (one of mi amigos on Team Twisted has this problem-nothing we can do). Google seems to be wanting to go iron-fisted in security and sacrificing FOSS development for "security".
There was a post on r/Android tonight outlining some of the more obscure technical problems, and outright annoyances for developers as well in the current Android landscape generally: https://www.reddit.com/r/Android/comments/56qr4z/why_i_am_giving_up_on_android/
FWIW....he mentions specifically kernel 3.18; that kernel is not only used by the upcoming Pixel but according to the posted v20 system dump, a few subforums down, is the kernel v20 is going to ship with as well. When that OP is speaking about shipping a brand new device in Q4 2016 with a 2-year-old+ kernel ceasing upstream patching in 2-3 months as being insanity.....he's not just talking Pixel, he's also talking v20.
I wouldn't borderline rant on it unless the device had a ton of potential...which v20 especially does, and seeing LG squander it with shortsighted planned obsolescence is frustrating.
Personally I am okay with not too many roms. All I need is root for Viper and a few other apps.
I really think that I'll get this phone to replace my G4. I had to come to terms that the bootloader will never be unlocked on all models except T-Mobile and certain international models. I've also accepted that there will be absolutely zero dev support.
Don't fault me for being pessimistic. Being optimistic with the possibility of Dev support and observing how the G4, G5 and V10 turned out is plain foolish.

Their listing for the VS995 is incorrect/incomplete compared to what the LG Electronics sent to the FCC and has on file. Read and compare, some of their entries are wrong (VS995 does indeed have Band 25), some like Band 66 are left out or missing (VS995 has that too). WCDMA is either seemingly absent although maybe they call that "UTMS". CDMA support is also flawed (should be 850/1900 for VS995 not 800/1900). I don't have easy to call up numbers for US996 ATM, but one way or another-their band support table is incorrect.

The phones are not radio band identical.
Yes the US996 is compatible with Verizon. I will have it on their network within 30 minutes of unpacking it from the box.

Please report back once you have it working. I'm very interested in doing this too. I'd love to not get stuck with the bloat.

Actually, devs that tried supporting Note 7 are now interested in developing for the V20 from the online polls since the note 7 has been officially canceled
