I have a G920v and want to use it with ChinaTelecom that is the only CDMA carrier in China. I rooted the phone and unlock the LTE band 3 but still can't use 4G. I did much research and found Verizon would lock srlte by carriers_policy.xml in EFS or telehphony.db in /data/data. But I can't found these files in G920v. Anyone know how to do?

Yes. I read the thread and try following intro. It can enable LTE BAND 3 but can't make SRLTE works. The phones from VZW often limited using LTE by other CDMA carriers by a xml file named carriers_policy.xml. To find it, you must connect the phone to QPST and run the EFS explorer. It is placed in /policyman. But I can read any by EFS Explorer with my SM-920V. A error shows that the format of EFS partition can't be recognized.

What is QPST?
I am curious if the VZW S6 actually has the proper antenna and path for Band 3.
I'm sure the chipset has support, but it doesn't seem like there is a resource that specifies what the bands the phone actually can support.

I confirm Band 3 works. After following the post about Service Menu to unlock Band 3 I tested FDD LTE of ChinaUnicom and it worked well. But this carrier run a GSM network so I needn't do more than adding its APN. But for CDMA network, some other operations need to be done.

Thanks, I think it is crazy how there is seemingly no official resource that lists exactly what bands a phone could support. The FCC docs only show bands 13, 4, and 2. Who knows what LTE band capabilities a modern phone might support?

Can you clarify, to use LTE band 3 on a GSM based network, does anything need to be done to the phone (besides the APN)?
(after trying to use the HTC One M8 on Telstra LTE in AU didn't work, I was hoping the S6 would!)

If you can operate NV items by QXDM, To enable bands not listing in FCC isn't too difficult.

In other words, bands listed here are actually fully supported by the device? My impression is that the chipset may supported the bands, but that doesn't mean there is an full RF transceiver and antenna path.
try this :
*#27663368378#
go to nas, and choose ur preferred network. reboot. if no signal, ##3282# go to bsr, tap the get lte file, tap until you got the signal and everything works.
Type ##3282# and you will find a option to enable the hiddenmenu. I have tested that 's not need to be rooted.
It's truth that enabling every band is impossible. But at least I know Band 1 and 3 are actually enabled. I tested to confirm it. Of course, there is some other operations to enable band 1, but it's not my purpose for this post.
Now I want to get help from someone to find a file like /efs/policyman/carriers_policy.xml in Sony Z3v and Moto Droid Turbo. It can be found by QPST EFS Explorer. But for G920V or G925V, EFS Explorer can't take effect.

Can you tell us how you get the band 3 working? If I go to service mode and if I want to activate band 3 the "*" never stays next to the band 3 line. I works for band 2,14,17, all line as well.
Thanks in advance
*** edit ***
running stock version AOC3
in service mode/UE SETTING MENU/STTING/SYSTEM/"LTE BAND ON/OFF" When I try to enable band 3 I get the message : "not support". When I try B4: I get the choice between enable and disable.
Do you run a newer version than me lostvangel? Did you enable LTE bands with the menu LTE BAND ON/OFF?

Use to calculate Qualcomm NV items for adding GSM / WCDMA / LTE bands.
Do you want to add any GSM / WCDMA / LTE bands to your phone? Then use this app to calculate all needed NV items.
This app is only useful for phone with a Qualcomm chipset.
If you don't know how to add GSM / WCDMA / LTE bands to your phone, please refer to this thread. That thread is for S5 model, but the same principle is also applicable for many other phones, e.g. Samsung, LG, Sony, HTC, Nexus...
You also need some NV editor software (e.g. QPST, QXDM, EFS Professional...) on the PC to write these NV items to your phone.
>> NV items description:
- Adding GSM / WCDMA bands:
NV 01877 - RF Band Configuration
NV 00441 - Band Class Preference
NV 00946 - Expand Band Preference 16 to 32 Bits
NV 02954 - Bits 32 to 63 of Band Preference
- Adding LTE bands:
NV 06828 - LTE BC Configuration
NV 06829 - LTE BC Configuration DIV
DOWNLOAD: https://play.google.com/store/apps/details?id=org.vndnguyen.nvcalc
reserved
This app can show the calculation result in 3 formats: Decimal, Hexadecimal and Byte-swapped Hex.
Update v1.0.5:
- Fix UI issue on some devices.
- Add separate notation settings for GSM/WCDMA and LTE calculation. You should not change the default settings unless you know what you are doing.
I'm intersted in Qualcomm NV access, but not for cell band issues. There appear to be GPS issues with some Samsung phones, and there is some indication that those issues are related to a NV "privacy flag". Apparently older ROMs can turn this bit on and off, but newer ROMs don't - whatever value was left there is "stranded" there. There are people flashing back to CM10.x, setting this bit, then flashing back to CM11. I'm presuming that what is really happening is that they're tweaking this on NV location.
If we could simply read the NV location, we could compare its value to GPS functionality, and see if this is really the issue.
If the above is true, and if we could simply write this one NV location, we'd have a heck of a lot simpler GPS fix.
Thanks, vndnguyen, for your app. And it would be very nice if you add CDMA bands to your app. Thanks again.
if i am interested in enabling umts bands in somewhat old msm7227a based motorola, running gb 2.3.7, with no custom recovery, no custom roms or anything, but rooted.
should i even try?
thanks for making this, i wonder if my Snapdragon 600 on LG G Pro E988 can use this to enable China's TD WCDMA and TD LTE, since FDD is kinda different than TDD

Got a question. I found a discrepancy in your calculator.... Your NV calculator values do not match the NV value of the LTE bands my phone already has. So, how can I trust the calculator to give me correct values for additional bands I wish to enable?
It's at the bottom of this post, but I am putting a lot of information about my phone first, so you know the whole situation.
I have 5.2" 1440p, 3GB RAM Moto Maxx (XT1225), which has Snapdragon 805 -- same as the (Motorola) Nexus 6. In fact it was being tested by Google to be the Nexus 6 (or a Nexus 6 variant) as late as mid-August -- but Google decided to go with the larger size variant and only the larger size variant.
Motorola re-purposed this phone as the Verizon Droid Turbo (XT1254) in the USA and as the Moto Maxx (XT1225) now being sold in a handful of Latin America countries. We already have root, TWRP recovery.
When this phone was being tested by the FCC, it had these LTE bands:
But now being sold as the Moto Maxx (SAME FCC ID number), Motorola enabled more GSM bands and changed one of the LTE bands.
They disabled LTE band 5 (a minor AT&T LTE band), and enabled LTE band 3 (which is used more in Latin America countries).
QPST confirms the 2G/3G bands Motorola now claims for this phone:
Which means the LTE bands they now claim (2, 3, 4, 7, 17) are also probably correct.
Again this phone has the SAME FCC ID NUMBER. And as it's being sold in Puerto Rico (U.S. territory), that is very important. That means there's been no hardware change since U.S. FCC certification -- only software change.
Motorola also promises it has the SAME HARDWARE (including antenna) that the Droid Turbo (XT1254) has (even though the Droid Turbo has a different FCC ID number):
This is also important. It means really, Motorola could not sell the Moto Maxx (XT1225) in Puerto Rico (U.S. territory) under that FCC ID number if any radio-specific hardware had been changed at all.
Thus, we know the additional GSM bands, change in the LTE bands by Motorola was software modem change.
With me so far?
___________________________
Now the discrepancy...
In QXDM NV browser, in Line 6828, the XT1225 phone showed a value of 65630 (for LTE bands 2, 3, 4, 7, 17).
Yet, according to your app, with THESE LTE BANDS enabled (2,3,4,7,17)...
it should be THIS value: 65614.
Now I admit that's CLOSE, but it's not the same.
Therefore, how do I trust the calculator to let me enable MORE bands if this default number does not match in your calculator?
I have edited the values of that line to theoretically enable more LTE bands, but if the beginning number from the phone does not match what your calculator number says, then what exactly have I enabled?

I don't how how many bands does your phone support. But if the value of NV 6828 in the QXDM NV browser is 65,630, that phone should support the following bands: 2, 3, 4, 5, 7, 17.

So, you are saying the phone supports LTE band 5 out of the box, even though Moto only lists 2,3,4,7,17 on the retail specs?
That after FCC testing they only enabled additional LTE Band 3, but did not disable LTE band 5?
If so, that's interesting.
Only to get you correct: this mod is only to extend the range of usable LTE/GSM bands for roaming, not to extend your connectivity while using your default provider in your home country (e.g. to get better coverage in areas where your default provider has a low signal strenght), right?

Or when changing from one carrier to another in the same country. Many carriers lock down bands the phone could receive, because they want the phone to only be used on their network.
Okay so I'm not really understanding the whole idea behind this. I have a Sony Xperia Z(C6603) and my phone already supports the LTE bands(LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20). My problem is that by default my phone and service provider should be able to have LTE working since my service provider also supports LTE band 4 and 7 on their network but upon choosing LTE network modes it has no reception at all, only 3G and HSPA. So I'm assuming I need to do additional unlocking here on my end for my phone but am not really sure why.
I'm able to access through the hidden menu of *#*#4636#*#* and change radio bands and network modes:
But I haven't changed the radio band and tested it yet because I don't know what the outcome will be and if there are any risks or hard bricking of it and don't know how to revert back to default. My service provider's network supports LTE band 4(2100MHz) and band 7(2600MHz). Would I need to go through QXDM to have these 2 frequencies enabled on my phone? Because I noticed how from the radio band list of my phone shows Euro Band which ends up to be 2600MHz but I'm not sure if that's how to enable LTE because it's Euro radio band. Am I okay as it is with my phone's default radio band and just unlock band 4 and 7 somehow through QXDM? Sorry I'm just really clueless and don't want to risk hard bricking my one and only phone.

Your provider supports LTE bands 4 and 7. Of those two, your phone can receive LTE band 7, but you don't see it. Are you sure LTE band 7 is in your area?
My carrier supports five different LTE bands (and my phone can receive them all), but in my area I only see two of those LTE bands. The others are not used in this area by my carrier (AT&T).

Yeah my carrier supports band 4 and 7 in my area, the towers are everywhere.
I checked it using this website: http://www.ertyu.org/steven_nikkel/cancellsites.html
both 2100/2600 are within all the cellular towers in my area.
edit: so if I'm able to choose LTE network mode on my phone, does that mean the LTE network mode consists of all these frequencies of LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20? So everytime I change to LTE only or LTE/GSM etc etc, automatically my phone has 2100MHz and 2600MHz included? Which means I don't need QXDM to unlock anything further? It might just be a sim card defect or something maybe. Sorry I'm just trying to understand more
Hi
I am trying to use a US note 3 (n900a) on Europe, but I frequently lose connectivity (although bars are full). The only solution I found is to fix wcdma to 2100 freq, however this also means that I lose reception when there is only GSM coverage.
This app seems to be the ultimate solution for me to calculate a custom NV for GSM+wcdma2100. Am I right?
If so, may I use a NV writer without a box, by just using my usb cable?
Thanks a lot

If you don't have coverage and you have LTE it will keep scanning -> battery drain

This works in Europe too
Working in Uk?
The strangest thing... I enabled said bands while I was visiting Pakistan and it IMMEDIATELY worked (provider there uses band 3, 1800 MHz) It worked just fine in Dubai as well, also on band 3 and on my EE sim on roaming on etisalat. But then I get back to Uk and still no LTE. Just HSPA!
I am on EE network which I am sure uses band 3 as well. I know there is an LTE signal in my area because when I pop my sim in my wife's iPhone 5 (not 5s) it picks LTE immediately (which I believe is only capable of band 3 in UK)
Also, I am not getting LTE on my Verizon anywhere at all.
So I know band 3 was unlocked because it worked great in Pakistan and Dubai but its not working here. Anyone have any ideas why this is?
@BobbySteel: does yours work in Uk?

Great job
What are the default LTE bands the verizon m8 comes with?
Also is it possible to unlock AWS HSPA+ bands?
I have the exact same problem. I can't get any UK sim cards to reliably work in the UK but it works well in every other EU country I'm in. I've tried both Voda and O2 UK. Strangely though there are a few locations (near Victoria for example) where 4g *does* work. But it's geographically small and other areas my old sgs4 got 4g don't work on this handset w the same sim. Bizarre.
I was hoping this would be a more popular thread but guess the phone is getting old now...

TMO uses LTE bands 2-4-12 in the continental US and Verizon 4-13. Therefore you should unlock bands 2-12 to use both carriers.
So, NV6828 and NV6829 original values(4104) must be replaced with 6154. Hope this helps.

I have the exact same problem. I can't get any UK sim cards to reliably work in the UK but it works well in every other EU country I'm in. I've tried both Voda and O2 UK. Strangely though there are a few locations (near Victoria for example) where 4g *does* work. But it's geographically small and other areas my old sgs4 got 4g don't work on this handset w the same sim. Bizarre.

Both Vodafone and O2 use LTE band 20 in the UK, are you sure that band is enabled?

Thanks, yeah I've been getting lte since September when I switched over to T-Mobile, so that's not really the issue even though I thought that was it,... I think my issue it's cc with the aws band that T-Mobile runs on that I don't get that's the culprit... Any ideas on how to get that going? Cuz I get wcdma lte and basic 2g gms, but when it switches from tower to tower, it's what in having issues with

Hi All,
I was recently on holidays in the USA which using my Photon Q sim modded by Cornholio I was able to get LTE on T-Mobile. This was only in areas where they have re-farmed 1900 mhz (band 2) to LTE. I'm not sure if this makes a difference but I also changed nv 6828 for 1900mz bands 2 & 25. So in theory LTE should work on AT&T where they use 1900 mhz band 2 LTE. AT&T was was coming up a lot when I was doing a network search. It is listed as AT&T 4g.
Regards,
Sebastian

Hope you enjoyed your visit...
I've never played with any of this, but I'm an AT&T user in US... what exactly are you saying to try setting in the phone in order to try to get LTE on AT&T.... and if there's any way to know if AT&T is using that band in a particular area?

Hi,
This is what I did with my phone to get LTE was the following: Using the phone dialer
*#*#4636#*#* and in phone information menu change data to LTE/GSM/WCDMA
##3282# and in the LTE menu make sure that you have LTE as enabled, if not edit the value to enabled. You need to use the msl code for your phone to do this. I have an app to do this if you need.
To see if AT&T 1900 LTE is available in your area, go into settings, mobile network settings, network operators and choose the option search networks. A list of available networks will come up. If you have AT&T 1900 LTE band 2 available, this will be listed as AT&T 4G. Tap on this and you should be able to get LTE. The Photon Q lists LTE as 4G in the status bar on the top of the phone.
Hope that this is some help
I am leaving the post paid cell service and going prepaid.
I since majority if prepaid US prepaid 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 for carrier versions or does the Sprint version support (once unlocked) support AT&T and T-Mobile.
There's only 1 model variant in the US now - they all have the same band support - it all depends on firmware as to what bands are active.
But one thing to consider is that while a Verizon/Sprint phone may work on Tmobile/AT&T the same might not be the case the other way around because the AT&T/Tmo phone will probably have the bands disabled in the FW
Just to show this is my tmobile S7, wcdma bands that are enabled - so seems it would support Verizon/Sprint on bands 800/850/1900/2100 -- 2100 is a band not listed on Phonescoop FYI

Guess we'll have to wait until a Sprint/Verizon person gets their phones and get into the service menu to see what it looks like
Wasn't sure if they were the same thing (left Sprint well over a decade ago for GSM and never looked back lol)
But based on your info, then my first comment is probably true - Tmo/AT&T variants will not work on Sprint/Verizon due to not having the proper FW

Is this right? The FCC filing shows 5 models (SM-G930V [Verizon], SM-G930P [Sprint], SM-G930R4, SM-G930A [ATT], SM-G930T [T-Mobile]). It shows each version having support for different bands.
How would one go about changing the firmware? For instance, if I have the VZW version (doesn't support LTE Band 12) and want to use it on T-Mobile, how would I change the firmware to T-Mobile's?

As for FW change, not sure how that would go. We shall see what happens when the Dev's get their hands on these and start to figure it out.

Has that been ever done successfully on any of the carrier devices? You couldn't do that on the S6 to enable certain bands. I'm not too familiar with the other devices.

Well looking at Phonescoop, the S6 had separate CDMA and GSM models. Based on my understanding of the S7, there is 1 phone for the US market (where each carrier has their own model #) but internally the phone is the same.
The only other phone I can think of that had 1 variant for the US market was the iPhone (where each phone internally was the same and the bands that were active was dependent on the FW)

I think on the S5 you could change some of the NV to enable different bands. The iPhones are all one variant and they don't disable certain bands either. I have a 6S+ on T-Mobile (supports all bands); if I swap the sim for Verizon, it'll work on all of Verizon's lte bands as well. The S7 for verizon shows support for bands 2/4/5/13 so I'm not sure if I were to place a T-Mobile sim that it'll enable band 12 since it's not enabled on Verizon's version.
I guess we'll have to wait and see if it's truly one variant of the S7 in the US.
I'm in the UK, I'm wanting the S7 Edge - but don't want the 8890. The screengrab shows it supporting the main UK bands too.. Hm! Can you get simfree phones in US?

Figured out on the Tmobile variant how to set preferred band.
For me Band 12 is great for calls/texts in my building but HORRIBLE for data so I always switch to Band 4 as my only lte band (which means I don't get calls since I have VoLTE off but no biggie).
To do this on the S7 requires a few more steps than the S6, you have to
*#2263# for service menu
Select clear all bands
Then select LTE band preferences and choose the band you want
Then hit the more button(top right hand corner) and select back
Then hit Apply band band configuration
To revert back to normal go back into the service menu and choose select all bands and then choose apply band configuration

Well another thing you can do is go in and specifically turn band 12 off only and will still net you calls and whatnot

We normally can purchase phones outright but they are usually branded by their carrier. AFAIK, there wont be a unbranded version in the US. However, isnt the S7 doing something with the phone locking to the first sim/carrier being placed in the phone?
i have a g930t that is working with a Verizon sim card in it . and this is what i did
1: i used the sim unlock app on the s7 tmobile to unlock my phone
2: then flash g930u firmeware
3: i dont know if this one helped or not but i did *#2263# to slect all the bands.
4: turned off the phone
5ut the verizon sim card and turned it on
6: after it finished booting up the phone you will see a message on the screen that will say something like" need to reboot to configurate your sim card" hit ok and let it reboot.
enjoy
Can one use a G930P (Sprint S7) on T-Mobile USA with full band usage? I am assuming the phone would need to have a custom ROM on it.
I cannot get a definitive answer on this. When I check some sites it shows that this international model SM-G955F has band 12 which is what I need for Volte on T Mobile:
https://www.frequencycheck.com/models/G9Yo5/samsung-sm-g955f-galaxy-s8-plus-td-lte-samsung-dream-2
http://www.phonemore.com/phone/samsung-galaxy-s8-plus-sm-g955f/3234
But on the Amazon site to order the device it does not list Band 12.......
https://www.amazon.com/dp/B06XYKR7GP
Here is another posting of it and this list no bands....
https://www.amazon.com/Samsung-Galaxy-64GB-Unlocked-Phone/dp/B06XZRMCS7/ref=pd_sbs_107_1?_encoding=UTF8&pd_rd_i=B06Y15D6RP&pd_rd_r=S8FN2DDKWM54QN8JXJ6D&pd_rd_w=5nH47&pd_rd_wg=uVQ72&refRID=S8FN2DDKWM54QN8JXJ6D&th=1
SO, does anyone have this actual model and can actually check the LTE bands available on that model for me? I would greatly appreciate it before I spend that kind of money. I definitely want the Exynos unlocked for ROM, root, etc. If you are nopt sure how to check here is an app I found to check what 4G bands your phone supports...

I do not know if the app I posted will work, but try this method if fails:
If you go in to the service menu by dialling in *#*#7378423#*#* then go to service info then configuration. All the working bands are listed there

The SM-G955F? Has band 12. If you plan on using it on T-Mobile you need to make sure it also supports VOLTE on their network.
I'll be getting mine next week and will try to confirm if it has VOLTE on T-Mobile.

well they usually do if they have band 12. I will be happy when confirmed, either way I will be making the leap, getting rid of the t mobile branded and getting the G955F exynos to have some fun on, lol

According to the FCC listing it supports the following US bands 12, 17, 13, 26, 5, 66, 4, 25, 2, 41 so aside from band 30 it has all the bands needed to work great on AT&T and T-Mobile.
It also has carrier aggregation with US bands with the following combinations:
2+12
4+12
4+17
12+12
66+17
41+41
66+66
and 3 band carrier aggregation at the following bands:
4+12+12
66+12+66
41+41+41
Usually the FCC info is the most accurate!
*#2263#
Will like to know as well
I also looked the options.. this is what i understood..
amazon and other ebay list the International version of ASIA where Band 12 is not listed.. and no Region lock.. you can use any SIM on this..
EU version has Band 12 listed, but it has region lock enabled, so you need EU sim and get it activated by making call for 5 min. then you can put any SIM. but band 30 is not supported (ATT)
i enquired on Clove they listed Band 12 is supported.. whoever have the device can confirm on this.
