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?

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 am leaving post paid service and going pre paid.
I since majority if prepaid US carriers are Sprint, T-Mobile and some AT&T. I want a GS 7 that will support all three carriers with as much bands possible.
Any suggestions or does the Sprint version support (once unlocked) support AT&T and T-Mobile.
Technically, any GSM unlocked phone would work on any GSM network, but that wasn't your question.
I ordered the sprint version to use with cricket (at&t network). What I read, the sprint version will support AT&T better than tmobile. In the end, once rooted, you could add in the band's not supported by default.
Music to my ears!
Will have to get the Sprint version and hope for the best.

It just seems that way, or it's because it has a better antenna in general. LTE Plus doesn't get you a stronger signal. The beamforming that helps at the cell edge is a tower-side enhancement. As long as your phone supports band 41, you're able to take advantage of LTE Plus - just not the Carrier Aggregation component.
I am very eager to see what happens in this regard as well. Sprint is notorious about locking down their phones to include very few LTE modes so that the phone is truly only for Sprint. Samsung's CDMA version of the Galaxy phones have been crippled in this way all the way up to the S6.
You can see various phones like the S4, S6, LG G4 and the S7. The S7 CMDA variant does not appear on this comparison chart yet but I'm hoping that it won't need to.
http://www.phonescoop.com/phones/compare.php?p=4066,4769,4773,5081,4928
The last phone in that comparison is the iPhone 6s Plus, which is the same no matter which carrier you use worldwide. I really, really hope Samsung does the same thing.
The only other phones with lots of LTE bands like the iPhone on Sprint is the Nexus 5s/6p and Moto X Pure.
PLEASE let LG and Samsung include all the default LTE modes by default on the CDMA versions of their phones!
Edit: nope, Sprint made Samsung get rid of the most important worldwide LTE band, 7, along with 13 and 20. LAME.

I'm thinking of buying the SM-G730P (Sprint) version of the Galaxy S7 even though I was all the years on Verizon and they are for sure the better service and have more coverage, at least here where I live, but the reason I wanna buy Sprint is just because Verizon just makes Samsung phones much more secure, and locks the boot loader, now the question is, First of all does Sprint still lock their LTE phones? And second of all, will an unlocked Sprint phone work on the Verizon network, and will it work overall perfectly when I'm aboard, on the International GSM network? And last of all is there a different in the build of this 2 phones, Verizon S7 and the Sprint S7, besides the bands

Today's news concludes that all US (Qualcomm) variants of the S7 indeed have a locked bootloader except for a select few apparently. Verizon and AT&T lock the bootloader tighter than others, such as Sprint. Sprint and T-Mobile didn't lock the bootloader themselves but rather Samsung. Samsung locked the bootloader to better add security to their consumers and there's been hints they may release an unlock kit/tool for developers but this hasn't been confirmed.
I got Sprint to unlock my G930P and works perfectly with AT&T. The S7, at a hardware level, is the same phone for all US variants where the only thing that changes is the software. Meaning a Sprint phone on the Verizon network would essentially have the same network performance as if you were to use an actual Verizon variant. Once the device is unlocked, at least for me, it knew my sim was on the AT&T network and switched the bands to AT&T on reboot.
Internationally, I'm not sure. There is an option to enable Global bands in one of the hidden menus in self-service but I'd assume it'll cover enough bands to provide you with what you need minimally. (I've never gone international before so can't say from experience)

GSM will work as expected.
LTE, however, will be crippled depending on the country you go to.
The updated spec list:
http://www.phonescoop.com/phones/phone.php?p=5081
According to that list, Sprint purposely took out three very important LTE bands: 7/13/20. Why does that matter? Because much of the world uses these three bands, especially band 7 and especially Europe! Sprint purposely crippled the LTE radio modes for this phone and I cannot understand why.
So yes, you'll probably get normal GSM and some LTE if they offer one of the other bands but Sprint purposely disabling or deleting the commonly used international LTE modes abroad is just anti-competitive and backwards.
Will rooting or unlocking this phone allow the use of the bands that were locked by Sprint?

The splash screen says LTE Plus, not LTE Advanced. LTE Plus is simply the new branding for Sprint SPARK. Was that the OPs question?
LTE Plus is not Sprint Spark , its more in depth. Carrier aggregation by antenna beam forming.
For those interested, Sprint is releasing an unlocked S7 that works on all the carriers and has a full range of US LTE bands:
http://www.phonescoop.com/articles/article.php?a=17870
I was curious if anyone had tried dual CDMA carriers on their dual sim G4s. My understanding is that for 3G cdma voice the device itself is registered as opposed to a 3G GSM which registers the sim, so only one CDMA service could be active at a time. Changing to another CDMA carrier would mean going through Verizon's or Sprints's activation process each time you wanted to change to a different sim (this was my experience with a 3 sim adapter). I'd love to hear someone more knowledgeable chime in on this subject and provide some feedback on whether or not this is how it would work with a dual sim moto G4.
I'd love to have dual CDMA sims because I have free service with ringplus (Sprint MVNO) but it's spotty in rural areas, whereas Verizon has the most solid signal in the remotest regions.....however I think it's a pipedream. I am aware that you can do a CDMA LTE sim switch and get data without a problem (I'v done this with a triple sim adapter), it's voice and text that I'm interested in being able to switch to, without having to go through the activation process. And because I need this voice and data in remote areas without LTE, VOLTE isn't an option.
I hope that isn't too convoluted or arcane a question, I realize it's not a common scenario. But with the Moto 4G being carrier friendly to all the north american providers (GSM and CDMA) and having a dual sim slot, it's the first plausible solution to what I'd like to achieve.
Unfortunately, the only G4 models that have CDMA are the US models (XT1644 G4+, XT1625 G4, XT1607 G4 Play, XT1609 G4 Play for Verizon Prepaid), and the US models are only available in single-SIM format.
From what I've been gathering, there are no dual-SIM CDMA phones that fully work with US carriers available yet. The OnePlus 3 comes sorta close, it's dual-SIM and has CDMA Band 0, which Verizon uses in most markets, but at the moment it either works in 1x/EVDO mode for calls/text, or LTE mode for data. However, it's lacking CDMA Band 1 (Verizon & Sprint) and CDMA Band 10 (Sprint), so it's not ideal. It's also lacking Verizon's main LTE Band 13, and all of Sprint's LTE bands.
Slightly good news, though. The upcoming ZTE Axon 7 is dual-SIM and FCC testing indicates that it fully supports all US carriers, including all Verizon and Sprint CDMA bands.

I'll keep an eye on it.
Would the concept work the way I described in the first post though? I'm really curious if the phone would require sprint or verizon activation when switching cdma sims. I don't have a great deal of experience, simply my results with a multisim adapter. I was unable to test the adapter with a verizon and sprint capable phone (like a nexus 6) but tested it with an Verizon samsung s5 using gsm sims and a verizon LTE sim. The gsm sims (various at&t and t-mobile MVNO) were of course no problem, but switching to (or back to) a verizon LTE sim required teh verizon activation process (but not for data, as the LTE was active without activation).
Is it possible to have a dual sim (or even single sim) phone that supports both carriers (Verizon and Sprint) that could switch back and forth, or is the activation process simply inherreient with the way the devices imei's are registered on CDMA networks, and will always be required. For me going through the activation process for Verizon or Sprint when switching sims would simply preclude any practical usefulness with a dual sim cdma capable phone (although it would still have value as a dual sim with a cdma and a gsm sim).
Sorry for the late reply xtermmin and thanks for the info.

I can't speak for Sprint, as I have Verizon, but I do know that they're more restrictive than Verizon.
On Verizon, the only current restriction is a whitelist when you try to activate a SIM for the first time. You have to use a device that's in Verizon's "activation database", typically Verizon-branded devices, iPhones 6 and up, the Moto X Pure, and (at some point, if not now) the Moto G4 lineup. Once you have an activated SIM, you can stick it into any compatible device (be it from Verizon, another provider's phone, or even an unlocked phone that doesn't officially work on Verizon) and you should be good to go.
For example, I've been using my same Verizon SIM that I got with the HTC Thunderbolt (when it launched in March 2011) in numerous other phones (Verizon phones, US Cellular phones, unlocked phones, even some GSM/LTE-only phones) with no need to contact Verizon or use the website or anything. I've been able to just pop in the SIM, adjust the connection method on the phone if needed, and go.
As for your experience with using a dual-SIM adapter on the Verizon GS5, it might be due to the phone going into "GSM/LTE" mode when you insert a ATT/TMO SIM, but not switching to "CDMA/LTE" mode when you switch to your Verizon SIM (thereby only connecting in LTE mode). Might want to try setting it to Global mode (GSM/CDMA/LTE). The Verizon version probably wasn't tested for dual-SIM use, so it might just be the OS not knowing to switch to the other mode, or it might be an issue with the adapter itself.
Regarding an actual dual-SIM device with both SIMs being CDMA, I'm unsure if it causes any issues, as there's been no phone with that ability released yet (technically, someone can try dual Verizon SIMs in the OP3, but the CDMA implementation on that phone looks to be pretty half-assed, so I wouldn't use it as a baseline). Guess it depends on how the SIM slots are setup (if they share the same IMEI, or if they have different IMEIs for the two slots). If they're the same IMEI, I can see there potentially being issues, but if they're different (which should be the case for any modern name-brand flagship), there shouldn't be.
We'll know more once the Axon 7 releases. Unfortunately, ZTE has said that CDMA support will be coming in a software update later, but at least the phone is physically banded for CDMA, so we won't know for sure until then.
Actually the xt1644 have dual sim slots , one is hidden open the phone and you will find it
Is it possible to SIM unlock this phone? I've looked around but the threads I see all require a paid service or things that haven't even been tested. I don't want to throw money at SIM unlocking because I don't trust those paid 3rd party services. Is it even able to be connected to MetroPCS, if anything? I know it's a CDMA and GSM difference, but specs online don't show specified carriers like other phones would unless they support GSM and CDMA like the iPhone and Galaxy S7 and such.
Sprint will do it if you've met their criteria.

Doubt it. I think it has to be activated for 6 months first.
I have one and put in another carrier SIM card and it does not prompt for any unlock code. Sprint technicala support is useless
Good luck! I had a sharp aquious crystal with Sprint years ago and they refused to unlock it because I hadn't been with them long enough. ?

The Sprint compatible variant of the Moto E4 (xt1766) is likely network locked with carrier implemented encryption. On the Moto E LTE (xt1526), for example, the Sprint compatible variant, GSM functionality was disabled by the provider using a rather clandestine encryption method. Three of the device's partitions, namely, the /hob, /dhob & /pds partitions, were encrypted to prevent any GSM functionality with the global providers. To the best of my knowledge, as of today, no exploit or user-end modification has ever been discovered to decrypt the network restrictions. This is also the case with a number of Lenovo & Motorola Mobility manufactured smartphones, including, it would appear, the Sprint compatible Moto E4.
its possible
I must go back from my previous post and correct the statement I made regarding the SIM lock status of the xt1766 SPerry Moto E4. Unlike many of it's predacessors, the Moto E4 is not network locked via encryption or partition security. In fact, the Sprint/Boost Mobile/Virgin Mobile variants of the xt1766 is not SIM or network locked at all -- at least not in the traditional sense of the term. Rather, the apparent network restrictions are in the stock firmware (Android OS) itself. When the stock ROM is replaced by any of the several custom Android ROMs available for the xt1766 -- LineageOS 14.1, for example, the device will automatically recognize and support SIM cards from GSM networks such as AT&T, T-Mobile, Cricket, H20, etc. It should be noted here that the xt1766 has quad-band GSM capabilities (850/900 1800/1900), support for WCDMA Bands 1, 2, 4, 5 and 8, and supports LTE Bands 1, 2, 4, 5, 7, 8, 12, 13, 17, 25, 26, 44, as well as the newer 1700MHz LTE Band 66. So, if you're using an AT&T SIM or AT&T based MVNO or subsidiary, which uses LTE Bands 2, 4, 5, 12 and 17, voice, SMS/MMS, and 4G/LTE data are fully supported. If you are using a T-Mobile based MVNO or subsidiary, or a T-Mobile SIM, utilizing LTE Bands 2, 4, 12 and 66, you are also fully covered. Outside the United States, please check the specs of your global provider to make sure that the required bands are supported. It's also noteworthy that, whichever GSM provider you are using, it will likely be necessary to go to device SETTINGS>MOBILE NETWORKS and manually configure an Access Point Name (APN) for data and MMS services specific to your provider.

I have a Sprint Moto E (2015) and it seems that it is only SIM locked to US carriers. A foreign SIM seems to come up just fine without setting anything. Even let me change APN.
There are 3 sellers on eBay selling remote unlock service for the Boost Moto E4. Interestly, they all mention that unlocked E4 will not work in US. Whereas other people running 3rd party ROM has no problem using T-Mobile / AT&T. So I guess their unlock mechanism is different and perhaps bringing the Moto E4 into a state similar to the Sprint Moto E2.

All Sprint compatible models of the Moto E LTE (2nd Gen) 2015, as you correctly noted, are unlockable for international GSM carriers, but are GSM disabled for domestic use.
The Sprint Moto E4 (xt1766) is not SIM locked at all for domestic GSM usage -- at least not in a technical sense. The GSM restrictions on the xt1766 are coded within the stock firmware. Flashing a custom ROM and the APN fixes and blobs will enable GSM support. On the xt1526, GSM service is disabled via embedded encryption to the /pds, /hob and /dhob partitions. To the best of my knowledge, nobody has been yet successful in disabling it.
On the Moto E4 xt1766, the launch version of the firmware allows domestic GSM support, and even allows APN editing.
While I realize I've previously mentioned these points, I'm pointing out the key differences in Sprint's policies of carrier locking between the Moto E LTE (xt1526) and the Moto E4 (xt1766). The xt1526 was based on partition encryption, which is not alterable. And the xt1766 is firmware based, which obviously can be modified and removed.

Hi, I have a sprint Moto E4 (xt1766) that is rooted and has lineage OS installed as per https://forum.xda-developers.com/mo...neageos-14-1-moto-e4-qualcomm-t3690156/page36 but I get a No SIM when I put in a US TMobile SIM. (Without a SIM, I get "No SIM card -- Emergency calls only" so clearly, the phone recognizes the SIM. And the SIM works fine on a Nexus 4.)
I wonder what I need to do to get the SIM working on my XT1766. Any suggestions are appreciated. Thanks again in advance.
