[Q] AT&T LTE Band 17, Anyone got it Working on Verizon Droid Turbo?

OK, so I have searched around in these forums, found the thread where some people were able to unlock some bands for the MOTO MAXX XT1225. However, I just want to verify before I return the hastily bought Droid Turbo from Verzion (XT1254): has anyone had success unlocking LTE Band 17 to use on AT&T here in the states? Right now, it's the only issue I have with the device. I get HSPA+ no problem, phone calls, etc but LTE eludes me. I live in Durham, NC and I verified on my old phone that I use band 17 for LTE.
Yes, I know I should've researched more but hey, some guy on youtube said it works and apparently thats all I need to buy a phone. (Especially at the decent price of $550 for the 32GB)

This is job for @ChazzMatt and his knowledge of bands

There is no proof I have seen of being able to enable any extra bands on any of the Quark series. The only bands I have seen confirmed to work are the ones already enabled in the phone.
Based on FCC info there is no reason to believe the XT1254 supports band 17 LTE. I am quite sure there is nothing you can do to enable it. The XT1254 and XT1225 do share band 2 and 4 LTE hardware but the rest of the LTE hardware is different.

Yeah, other phones have had LTE and HSPA bands enabled, but usually it was bands which are enabled in the same device in other regions -- like Galaxy S5 European bands for USA or vice versa. The modem and firmware supports those bands, but Samsung had certain bands locked down or enabled, depending on where the phone was sold.
People have been unable to enable European LTE band 20 on the Moto Maxx XT1225 because no Quark phone has that band anywhere.
HOWEVER, LTE band 17 is enabled in all XT1225 Quark phones... so could LTE band 17 be enabled in the XT1250 (U.S. CDMA/LTE Moto Maxx/XT1254 (Droid Turbo) ? Theoretically, is possible, but I'm not going to say yes.
I delved into all this deeply months ago to try to enable LTE band 5 on the XT1225 -- since it was found by FCC certification tests, but Motorola didn't list in the Latin America specs when released. Then, after doing a whole bunch of work and confirming with the NV calculator dev, LTE band 5 was already enabled as was HSPA band 4 (for T-mobile). So, while knowledge is always useful, all my work was not necessary.
When the Moto Turbo XT1225 was released (same model number, same FCC ID, same SKU), Motorola FINALLY listed all the bands that are enabled.
@Steve-x is correct. Up to this point in time, no one has enabled LTE bands that are not already enabled. Still, LTE band 17 is theoretically possible since all the Quarks share the same Snapdragon 805 modem, and some do have LTE band 17.
In a similar way, many many people have enabled LTE band 3 on the Nexus 5 D820 and enabled LTE bands 2 and 4 on the Nexus 5 D821. I'm going to do that soon for my wife's Nexus 5, as we are going to Brazil this summer.

XT1250 on AT&T LTE Band 17
It seems the XT1250 and XT1254 are counterparts -- I just purchased a XT1250 thinking Band 17 was enabled, but only getting HPSA+ and no LTE.
Any luck, thoughts, etc on this lately?
THANKS

Not "counterparts", identical devices. The XT1250 (U.S. Moto Maxx) = XT1254 (Droid Turbo). Same FCC ID, same bands, same exact device. Since the XT1254 does not have LTE band 17, neither does the XT1250. The XT1250 is basically the dev version of the XT1254, with unlockable bootloader via Motorola website like the other Quarks.
While all the Quarks share the same hardware, including antenna, the radios are different. The XT1225 has a different FCC ID because it does have different radio.

The XT1250/XT1254 has CDMA bands which the XT1225 does not have or need. The XT1225 has more HSPA bands, different mix of LTE bands and more LTE bands. All Quarks share LTE bands 2, 3, 4, 7. But the XT1250/XT1254 has LTE band 13, while the XT1225 has LTE bands 5 & 17, plus more HSPA bands.

There is no way to "unlock" bands on any device. If your phone does not have a certain band, you're out of luck.

Correct, you can enable bands the manufacturer has disabled, but you cannot "unlock" bands that were not there in the first place.
On Qualcomm Snapdragon phones, some manufacturers like Samsung, One Plus and others apparently first make a global phone template for a phone like the Galaxy S5 which is sold everywhere, then disable the bands not needed in certain regions/various carriers. (If they did not disable those bands, the phone would be sort of like a Nexus phone -- but they do disable them because carriers want phones that only work for them, to lock in customers.) By using QPST and similar modem software people have had luck re-enabling those bands that were disabled via the manufacturer.
For people who don't know about this, google: "enable LTE bands Qualcomm" for starters... Heres' one brief article: http://pocketnow.com/2014/10/31/extra-smartphone-radio-bands
But if the bands were never there to begin with, they cannot be re-enabled. Can't create something out of nothing.
All the Quarks (XT1225/XT1250/XT1254) share LTE bands 2, 3, 4, 7.
Additionally, the XT1254/XT1250 has LTE band 13 -- as well as CDMA bands.
Additionally, the XT1225 has LTE bands 5 & 17 (but not LTE band 13), has no CDMA bands -- but does have extra HSPA/UMTS bands the XT1254/XT1250 does not have.

Theoretically, because the XT1254/XT1250 Quark (Droid Turbo, U.S. Moto Maxx) has LTE band 13 (but not 5 & 17) and the XT1225 Quark ("international" Moto Maxx/Moto Turbo) has LTE bands 5 & 7 (but not 13), you could enable those bands on all Quarks -- so that they all had 2, 3, 4, 5, 7, 13, 17. Theoretically, depending on if Motorola has similar process to Samsung in designing/manufacturing.
And realistically, probably not, if Motorola created two separate templates for the XT1254/XT1250 and the XT1225.

on Samsung phones, One Plus phones and some others like ZTE, the bands are disabled and can be re-enabled. Especially if the bands are present on a variant elsewhere in the world, there's a chance it can be enabled on your variant. There's tons of threads on XDA about enabling extra LTE bands on various phones.
But for the Quarks, if LTE band 1 or LTE band 20 (popular in Europe) is on none of the Quark phones (they are not), then you can't enable something that's not there in the first place.
Additionally, on the Quark phones, if Motorola has two completely separate blueprints/templates -- whatever you want to call it -- one for the XT1254/XT1250 (which are EXACTLY the same phone, same FCC ID, even if different number) and a different one for the XT1225, then you can't create a "universal" Quark sharing all the bands they both have. You could NOT create a Droid Turbo with LTE bands 2, 3, 4, 5, 7, 13, 17.

PSA: The Droid Turbo and The AT&T Network

Hello folks,
Recently I entertained the idea of picking up the Droid Turbo and using it on the AT&T network. Everything that I read stated that one could expected to achieve HSPA or HSPA+ at best. I decided to test this and went ahead and dropped $100 down on a used Turbo courtesy of Craigslist. To my surprise, I have been able to achieve the most rock solid and incredibly fast LTE connection! See the image below for proof!
If you have questions, that I may be able to answer, please let me know! With all of this being said, for those considering picking this phone up and using it with AT&T, don't wait any longer. It is awesome!

That's not true and many, many people on here are using AT&T and T-mobile. You did NOT do a lot of reading and research, especially here on XDA! You couldn't have. Many, many people in this forum have been using the Droid Turbo on AT&T and T-mobile since it went on sale in 2014. Any cursory investigation shows LTE bands compatible with SOME of AT&T's bands and ALL of Verizon's LTE phones are network unlocked by order of the FCC.
The Droid Turbo XT1254 has LTE bands 2, 3, 4, 7, 13.
AT&T uses LTE bands 2, 4, 5, 17.
So, of course you can use the Droid Turbo XT1254 on SOME of AT&T's LTE bands. Just not all of them!

http://forum.xda-developers.com/droid-turbo/help/turbo-cricket-t3108577
But it's old news so we don't discuss it much anymore.
The problem you will have is in cities like Atlanta, GA where I live where AT&T uses LTE band 17 a lot. In places like that you will have HSPA/HSPA+. In areas where AT&T uses LTE bands 2 and 4 you will be OK. In northern part of Georgia when I drive to Chattanooga, that's mostly LTE band 4.
AT&T uses LTE band 5 very sparsely, and even then mostly (not always, but mostly) to supplement other LTE bands due to congestion. There are very few standalone AT&T LTE band 5 areas, where other bands are not also in use. So, for AT&T you mostly need a phone with LTE bands 2, 4, 17.
You have a phone -- the Droid Turbo XT1254 -- with two of those bands: LTE bands 2 & 4.
I have the sibling Quark, the Moto XT1225 -- so I have all of AT&T's LTE bands.
Get the LTE Discovery app. It will show you what bands you are using. You'll never see LTE band 17 unless someone figures out a way to unlock LTE bands 5 and 17 on the Droid Turbo XT1254 (theoretically possible since all Quarks have the same hardware and same antennas).
As long as you stay in places AT&T uses LTE bands 2 & 4, you will get LTE. IF you drop down to HSPA, it's probably because you are in an LTE band 17 area or just crappy LTE signal in general.
The XT1225 and XT1254/XT1250 all share LTE bands 2, 3, 4, 7.
The XT1225 additionally has LTE band 5 and 17 (more bands used by AT&T).

Hi there. Is there any possibility to use Droid Turbo on RingPlus (Sprint MVNO). CDMA would be enough for me.

Do calls and data work simultaneously using GSM sims?

i'll be installing BlissPop or OK when i get the device, wondering..
somebody with a turbo using it on Tmobile or At&t clear me this one up, you can have voice and data, right?, this is just a verizon issue, right?
never saw a clear answer for this question
also, what bands are supported??

Which "Turbo" do you have? Droid Turbo XT1254 or Moto Turbo XT1225? I assume Droid Turbo because only those people don't also give the model number.
There's two distinct devices (two FCC IDs), sold under three model names:
Verizon Droid Turbo XT1254/U.S. Moto Maxx XT1250 (same phone, same bands, same FCC ID) and
Moto Turbo XT1225/"international" Moto Maxx XT1225 (different FCC ID from XT1254/XT1250, but all XT1225 share the same bands with each other, and are the same phone).
These Droid Turbo/Moto Turbo/Moto Maxx are all under the "Quark" umbrella and except for radio bands are the same hardware, just like all "LG G4" are all the same hardware even though sold by different carriers in different countries.
All the custom ROMs support all Quarks. Custom ROMs over here are for all Quarks, ROMs (kernels, recovery, apps) over in the other Quark forum are also for the XT1254. Most dev work is still over there.
Of course Quarks with GSM/HSPA/LTE carrier SIM cards get simultaneous data/calls -- that's only a Verizon (CDMA) issue. But during phone calls on GSM/HSPA/LTE carriers, you will temporarily drop down to HSPA during the call (for simultaneous data/cellular voice), then jump back to LTE (data only) after the call is completed.

What is "OK" ROM?
We have 7 custom Marshmallow ROMs for the Quark (maybe 8 depending on how you count) -- they work on ALL Quarks, thanks to our CM dev.
But I'm not familiar with OK ROM. Oh, maybe you mean AOKP? See, I think you are just looking at ROMs here. Yeah, Bliss and AOKP are great, but we have TWO Quark forums. Click that link above and you see all the ROMs. TWRP recovery and BHB27 custom kernel and other ROMs live over in the other Quark forum.
Right now, seems Bliss and Resurrection Remix (Marshmallow) are the two most popular.
Since you don't have the device yet, just to let you know... the XT1254 need paid bootloader unlock via Sunshine($25). Thank Verizon. The other Quarks have free bootloader unlock via code from Motorola website. No, there's no free bootloader unlock for the XT1254. Just believe us.

As for what GSM/HSPA/LTE bands the Droid Turbo XT1254 supports? Well, let's discuss all Quarks. The XT1254 is yours.
The XT1225 and XT1254/XT1250 all share LTE bands 2, 3, 4, 7.
The XT1225 additionally has LTE band 5 and 17 (more bands used by AT&T).

Same advice with T-mobile and LTE band 12.

Now on AT&T or T-mobile you will NOT get VoLTE. AT&T restricts that to certain AT&T-branded phones and T-mobile restricts that to LTE band 12. BUT you will still get simultaneous data/cellular voice during phone calls on either carrier.

Most thorough reply I've ever received, yes I am going to get the Verizon model, and excellent I'm in the bay area, glad to know LTE will work!! This all sounds great, the person I'm buying it from has already done the unlock! Excellent deal all around I can't wait!
How is battery life with Doze?? I can't wait to use Naptime and see how it is

I received it, works amazingly I love this phone.

Noob question regarding phone compatibility on other networks

I have a droid turbo that I've been using for about a year using WiFi only. I make all my calls/txts via google hangouts.
I want to pick up a data-only sim for it, but am not sure what would be compatible with a Verizon phone. I don't need a voice plan at all (rather keep using hangouts dialer) and only need a small amount of data per month (sub 1GB).
What are my options? Thanks for the help.
EDIT: just realized this post should have been under q/a section. my bad

EDIT: just realized this post should have been under q/a section. my bad

The Turbo is an international phone that is compatible with both CDMA and GSM networks, and it is not SIM locked, so just about anything you plug in should work from a hardware standpoint. If I were you, I would look up the bands that your carriers of choice use and compare them with the bands that the Turbo are capable of receiving, and pick the carrier where there is the most overlap.

I have a droid turbo that I've been using for about a year using WiFi only. I make all my calls/txts via google hangouts.

You don't say where you live. U.S.? Europe? South America?
Here's the all the various bands of the Droid Turbo XT1254 (and the FCC ID clone XT1250):

The Droid Turbo XT1254 has LTE bands 2, 3, 4, 7, 13.

U.S.
AT&T uses 2, 4, 5, 12/17 (17 is a subset of 12) and some more LTE bands are coming on line like LTE band 30 -- but still in most places it's 2, 4, 17. I can show you my LTE Discovery logs for my XT1225 -- which has 2, 3, 4, 5, 7, 17. While I have run across LTE band 5 a few times on AT&T, it's mostly for supplemental LTE coverage in dense LTE zones. There's very few standalone LTE band 5 locations. But if I didn't have LTE band 17 on my phone I would be dropping down to HSPA a lot!.
Where I live (Atlanta metro area), 17 is use a LOT inside the city where I work -- while 2 and 17 are used around the perimeter and LTE band 4 is used up north of the city and towards the Tennessee state line.
If were on AT&T and you lived in an area where 2 and 4 are only used, you would be lucky. However, If you lived in an area where AT&T used 17 quite a bit (like inside Atlanta city limits), you would have to stay on HSPA a lot.
T-mobile uses 2, 4, 12.
Any MVNOs affiliated with those carriers (H20, Net10, etc.) would use those bands too, of course.
Stay away from Sprint and any of its MVNOs.

In South America, many of the major carriers use LTE bands 3 and 7, which is why the Droid Turbo XT1254 is popular as a used phone in that region. Although the "international" Quark 64GB XT1225 ballistic nylon + Kevlar was released for Brazil, Mexico, Chile, Puerto Rico -- a 32GB Droid Turbo XT1254 is a lower cost option for many with otherwise the same hardware specs.
XT1225 has more HSPA bands and LTE bands than the XT1254, and slightly different LTE bands -- but are otherwise the same phone. But the XT1254 came in two memory variants -- 32GB and 64GB, while the XT1225 was 64GB only. While there were 64GB Droid Turbos also with Ballistic Nylon + Kevlar, the ones flooding the secondary markets around the world seem to mostly be the 32GB models, which of course have no expandable memory. It's a trade-off. I won't buy a 32GB phone nowadays, even if it had microSD card (which the Quarks do not).
The XT1225 has held its value better than the XT1254 -- I think because of the 64GB memory and easily unlocked bootloader -- plus more HSPA bands instead of relatively useless CDMA bands most of the world does not use.

Europe.
Here's a list of the LTE networks in Europe:
https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe
Take UK for instance... Vodafone uses 1, 3, 7, 20, 38. You'll get reception on 3 and 7, but not the others. If you are unlucky enough to live in an area where there is no 3 and 7, then you would almost never get any LTE. But you could still drop down to HSPA.

WOW! Awesome and most complete of answers ChazzMatt! Thank you!
