Success with LG G3 D855 (International Version) on Tmobile (US)

Absolute Success with LG G3 D855 (International Version) on T-mobile (US). Pretty much all you need to change is the 6828 and 6829 value (both filled with same value).. You may not have to touch the others at all to enable LTE

I finally got 4G enabled on t-mobile (although the data icon showed as "4G" when on LTE and as "H" when on HSPA(+), obviously because it's an european phone and LTE is actually recognized as 4G over there. so I had to use g3tweakbox to set up the appropriate icon and now it displays as "4G-LTE" when on an actual real LTE, and as "4G" when on actually hspa(+) (which is the "fake" 4G here in the US compared to europe).

All you have to do is enable Band 1,2, and 4. That should get you real 4G-LTE on tmobile since t-mobile operates on band 4 frequency. I also took the liberty to enable band-12 (lower 700mhz) also which also increase stronger LTE penetration indoors and future proofing as soon as t-mobile starts to deploy that around my area this new year. The NV calculator app helps and also the mzTool also. Thanks to the developer.

And thanks to the OP for making this possible :). You may post my success on the main thread.

PS: DO NOT Mess too much with the nv settings especially trying to unlock all frequency else you might not get a signal or your network will drop in and out and unstable. And also for those that cannot get the lte option and had to go through enabling it through the hidden menu and also having to do that everytime your phone restarts, ALl you have to do is tweak and change some settings in the system/build.prop so you can have the 4G/LTE option available and fixed in the network settings. --Let me know if you have problems with that . Quote me or shoot me a PM. Good luck

And here are pictures of a test indoor (inside my building). THe original without the hack and editing , and the after the editing. I'm pretty sure I will get even alot better signal outdoors especially where there is a high signal for the LTE (as you can see I barely have any signal bar when i'm inside on lte..compared to the H+ on tmobile. I was just too cold to go out..lol :D

Is it worth trying for the Sprint LG G3 LS990? Wanting to use 4G LTE in Europe.
[Sony Cross-Device General] Epucci:
Yes I did. I unlocked all bands I need But LTE is not working.

---------- Post added at 02:48 PM ---------- Previous post was at 02:28 PM ----------

Here is my problem. I have a Z3 D6603 I purchased in AliExpress (http://es.aliexpress.com/item/Z3-So...RAM-16GB-ROM-5-2/32345773774.html#60588420851). When I got it It only received 2G signal. When I discovered this post I tried to unlock all bands that are used here in Argentina:

2G 850/1900

3G 850/1900

4G BANDS 4 and 28

My problem is that after i enabled all those bands finally had 3G working like a charm but can't connect to LTE/4G. SIM CARD is LTE. I have no Idea what to try to enjoy 4G in my Z3.

PS. After a lot of research I found out that my phone came as default settings all bands that the Z3 DOCOMO has in Japan. Probably this phone is from there and after being refurbished I got it.I don't know if this is the reason I can't get LTE.

Pictures of my phone with bands enabled but no LTE

You can see that even though bands 4 and 28 are enabled and LTE enabled I only have the 'H' right next to the signal...

Stop making up solutions that won't work (some of which are very risky). I've been trying to help you in multiple other threads (and you really need to stop making new threads). I would have told you to try this, if it worked.

You're wasting your time messing around when you can just accept the help that has been offered.

[Sony Cross-Device General] eurohunter:
Ok I just came across this post, and I read a lot trying to understand what it is about. I just want to make sure I am understanding this correctly. I will be receiving my Moto G US LTE (1st gen) xt1045 this coming week for use in Europe.

US LTE Model (XT1045):

UMTS (850, 900, 1700 (AWS), 1900, 2100 MHz)

4G LTE Bands 2, 4, 5, 17 (1900, 1700, 850, 700 MHz)

European LTE Model (XT1039):

UMTS (850, 900, 1900, 2100 MHz)

4G LTE Bands 1, 3, 7, 8, 20 (800, 900, 1800, 2100, 2600 MHz)

Are the steps shown in this thread supposed to allow me to access the LTE bands 3 and 7 (found in model xt1039) on the xt1045 which does not have these bands (assuming I can root the phone and get the drivers working)? The confusing point is the unlocking and the addition of new bands. Would this be considered an unlock of such bands on this phone, or an addition of bands? Thanks a lot :)

does that mean, that even if i successfully mod it, will i still have to buy a american sim or is this thread about modding the phone itself to "accept" other bandwidths?

I have a Global GSM Model Moto G (From Cricket Wireless/AT&T) . It is already sim unlocked and running with a T-Mobile USA sim card. It is working but it is lacking the 1700 HSPA+ band that the US model has. So it lacks some HSPA coverage.

Would it be possible to unlock that band?

US GSM Model:

GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)

UMTS/HSPA+ up to 21 Mbps (850, 1700 (AWS), 1900 MHz)

Global GSM Model:

GSM/GPRS/EDGE (850, 900, 1800, 1900 MHz)

Question though, in theory would this make the original sprint gs4, a "spark" enabled triband gs4? I haven't looked at the spec speed for the radio, but if it has the missing frequency (2.5Ghz i think) locked and this unlocks it i should be able to access spark speeds right.

It should work with any Qualcomm device, I do not know hat you are attempting but I found anyother way to enable AWS for Wind mobile in canada, it should also work for T- mobile in the U.S since AWs uses the same frequency 1700/2100 on Band 4.

I have a write on XDa but cant find it since I have not been on here for a while, but someone else posted it on REDDIT, here is the link

https://www.reddit.com/r/LGG3/comments/43hlvm/guide_getting_lg_g3_d852_canada_to_work_on/

Your phone is is basically the same as the D853 ust the ATT varient, so if you are attempting to just unlock AWS I would give this a go and if it does not work just reflash your original stock rom.

Must be missing something

First things first, thanks for this great, comprehensive guide!

I´ve had a little experience in adding LTE bands on Snapdragon 800 series-based devices, no issues so far. Now I´m trying to add LTE band 4 and UMTS 1900MHz on a Huawei G8 RIO-L02(Snapdragon 615), which are enabled by default on RIO-L03 version. AFAIK, there is only one processor version.

Process is straight: Get into diag mode, QPST will recognize COM port(as Snap-615 device) and QXDM will read NVRAM. I went into NV 6828 to make sure LTE band 4 was disabled and of course it was.

Then I modified values to enable band 4, wrote, turned off device and on again to check new data was there. Still I do not get an LTE connection.

As for 3G, modified NV 0441, 0946, 1877 and 2954(values checked with MZTool). In this case adding new bands lead to "No service" on phone(not even 2G).

What am I missing? As I told earlier I got some experience and feel quite comfortable on using these apps.

Any clue will be greatly appreciated. Thanks in advance.

You can unlock the all bands in your Qualcomm device but it does not mean that they will work all as it is ultimately depend on hardware too.

QPST and QXDM are the tools required for this setup to function.

Google for these terms will lead you to Xda where you will find the whole process...

Thank you very much for your reply.

I checked, there are two kinds of rom for this phone, korean and american roms. for korean and american roms it was mentioned that they support 700 and 800 mHz for LTE, respectively. my question is, how I can find that the inactivation of all of assistance bands is related to software or hardware of my phone. or it is better to ask you which hardware bands my phone has?

[Sony Cross-Device General] Nido221:
As for as I understand you are asking about the LTE bands support in your device.

Officially your Verizon mobile supports LTE 700 MHZ.

Now, it is completely upto your OEM that which frequencies supported antennas and filters it has installed on your device hardware. They don't publish the release notes so we don't know.

Actually at customer level it's a Hit and Trial method.

You can enable a particular frequency in QPST but it is also possible that it may or may not support by your hardware.

Theoretically

Qualcomm says about its S4 processors in its white paper

"Support for multiple radio frequencies:

Mobile broadband technologies are growing increasingly complex in their implementation. LTE is currently being implemented in over 40 different radio frequency bands throughout the world. To complement its wide range of modem standards supported, Qualcomm has designed the Snapdragon S4 Processor MSM8960 CHIPSET platform to address all commonly-used frequencies (from 700–2600 MHz) and bandwidths up to 20 MHz, allowing its customers to address any mobile network opportunity whether the simplest single frequency implementation to the most extensive multi-frequency global mode, whether 4G, 3G or 2G".

The hardware consists mainly two major components i.e base band and its associated components like filters and antennas.

For example you can unlock the LTE 1800 MHZ in your base band by QPST but it is also possible that your device do not have 1800 MHZ antennas alike.
[Sony Cross-Device General] dennis5pia:
Sorry I don't have the sprint M8. You have to be careful with that, and before make any changes have a backup or write values down before changing them.
[Sony Cross-Device General] dennis5pia:
Try to write those values to those items. They are for GSM 850, 900, 1800, 1900 and WCDMA 850, 900, 1900, 2100
[Sony Cross-Device General] yahyazadeh58:
If my phone support for example 1800 MHZ antenna, after using QPST, can it be activated or not?

An if it so, what is your suggestion? check the LTE bands that my provider has one by one by QPST and see if my phone has the LTE antenna or not?
[Sony Cross-Device General] dennis5pia:
Try enabling the bands your carrier uses and test it.
[Sony Cross-Device General] Nido221:
It must be activated as for as I know. However, my opinion is that you may activate all your carrier 's bands at once and check them out. But be sure to make a backup before starting.
[Sony Cross-Device General] yahyazadeh58:
Thank you again for your replay,

I checked in some tutorial that for activation of GSM/CDMA band(s) they used QPST, and for activation of LTE they used QXDM professional. Fortunately, I do not have any problem with my GSM/CDMA band(s), and they already active. Is it necessary to do the part two of the tutorial that I have attached its link as follow or not?

http://xdaforums.com/z3-compact/general/guide-unlock-z3c-international-bands-t3091344
[Sony Cross-Device General] Nido221:
I think that's more specific guide. You should use QXDM for LTE.
[Sony Cross-Device General] dennis5pia:
QXDM work fine for GSM/WCDMA bands, i just tried it. I set item 1877 to the GSM bands only (no WCDMA bands) and my phone only get connected to EDGE, then selected WCDMA only in network mode menu and lost the signal. Set the item 1877 back to stock value and 3G come back to business.
