[Q] Which variant of G3 should I buy on T-Mobile - G3 Q&A, Help & Troubleshooting

Before you reply sarcastically and imply that I should obviously buy the T-Mobile variant, I was curious because the international G3 seems to have double the amount of ROMs than the T-Mobile (D851). Correct me if I am wrong with this assumption. Only problem is that people tell me that the international variant doesn't support the same bands as T-Mobile LTE has. Is this still true, or does the international G3 now work on T-Mobile's LTE network? My end goal is to have a good amount of ROMs and best T-Mobile LTE support, so is there a way to flash international G3 ROMs on the T-Mobile variant by reflashing the bootloader and radio or would that still lead to a brick? Thanks for reading

I have the T-Mobile D851 G3 and before LP came out for the international models, I was able to flash their stock KK Roms with no problems. I ran version 1.2 of Cloudy Rom for quite awhile and that was a great Rom and very stable. I didn't have to flash any kind of bootloaders or anything to run the Rom.
It is true that development for the D851 is kind of slow compared to the international ones but there are still great developers for us. Skydragon is a great modified stock Rom and we do have some choices for some AOSP LP Roms too that are updated pretty regularly. I've ran a few of them and they run great. But I'm a stock kind of guy so I always revert back to Skydragon.

I have the D855 32GB using T-MOBILE . And no LTE only H+ getting around 4 Mpbs to 14.4 Mbps. I'm on their MVNO Ultra Mobile pre-paid limited data plan so its ok for me. Love the D855 cos its unlocked and already on CloudyG3 LOLLIPOP. Only paid $19 a month unlimited talk, text and International talk certain countries. But 100 MB data. Well if i need more data i just top up $5 for 500MB. I always on WiFi anyway.

Oh, did you flash the Cloudy ROM that was made for the international D855 or made for the T-Mobile D851?

Hmm, since I'm in an area where it is easy to get LTE, I would prefer a model that ensures LTE. But thanks for your input!

This is the version of Cloudy that I used that is still KK since we can't use a stock LP Rom on our phones yet. This one was for 850/851/855/LS990/VS985

[Q] Using this phone in Canada

Bought this phone on eBay few days ago and I started checking around about how to unlock it(though it'd be simple as any other phones, but I guess I was wrong). Found few threads talking about how to unlock it for US GSM carriers but barely find any information about using it in Canada.
Looking to root\use a custom rom and read that the CloudG3 rom will actually GSM unlock the phone,but will it work as well for Canada(will be used on Telus network)
Thanks.
The International unlock was actually the first to be done and originally how this phones comes (the LS980 is International GSM unlocked with stock Sprint rom). The GSM unlock for US carriers came after.
As long as your carriers operates on GSM 850/900/1800/1900 MHz your good to go.
Root, Custom Rec, and install Cloudy G3 or other T-Mobile based rom.

T-Mobile and H815 HD Voice/WiFi calling?

Hi everyone! I've decided that the G4 is the right phone for me. After using the G3 for 8 months and bouncing back between the Huawei Ascend Mate 7 and the Nexus 6 for the past few months, I've come to the conclusion that 5.5" screen size is perfect for my use and hand size - but I have a few questions before biting the bullet and ordering one.
I'll be switching over to T-Mobile for use here in the states from AT&T. Since I travel quite a bit to Europe, the H815 will cover the frequencies/bands I need to connect to data networks over there. My question is this - will the H815 version that's available to pre order support things like HD voice and WiFi calling? Or is this something that T-Mobile has to implement on to their phones and as a result, I must purchase their version of the phone? The HD voice isn't as important as the WiFi calling, I feel as if that is something worth purchasing the T-Mobile version for.
Cheers!
I believe you need the T-mo version for wifi calling. That's something they integrate into their version of the OS.

Wrightperspective is correct. The H815 has no native Wifi calling ability.

I see you're using the H811 model - that's the T-Mobile specific version, no?
And since I'll need the T-Mobile version, I now need to consider the LTE bands/frequencies of the T-Mobile version to ensure I'll have data whenever I travel to Europe.
Edit: I suppose some more food for thought could go towards ROM's and what not. Is it fair to assume that the H815 model will receive more support from devs since it's the international version and what not? I honestly think I'm okay with no WiFi calling if it means getting an unlocked bootloader quicker/more ROM support from the lovely XDA community.

It is always hard to predict what model will get dev support before it happens. Sometimes a phone with a world version will still get more support on one of the individual carrier versions. As for the frequencies, I did a brief compare based on the published information for the 810, 811, 815 over here http://forum.xda-developers.com/showpost.php?p=60992462&postcount=30

Help!!!!

Hi I have a lg g3 d850 (AT&T) and i want to install the tmobile rom, what do i have to do?????? thx
You'll need to sell your 850 and get an 851. The ROMs (firmware, actually) aren't cross compatible. There are physical differences in the phones.
However, if you want to use the 850 on T-Mobile, first make sure it is SIM-unlocked (talk to ATT or find an online solution), then just put in your ATT APN info and you should be good to go. Certain functionality won't be there (wifi calling).
There might be discussion about attempts to port wifi calling over to the ATT phone, in the 850 discussion areas. This area is for things that pertain to the 851 so you won't find much here.
Good luck!

LG G3 Models : which one should I buy for using Custom ROMs?

Hi Guys,
I am willing to buy a mid-range smartphone. I have some options like Moto G, Honor 5X, One Plus X etc. But, I want to go with the LG G3 to try my luck., as It'll be upgraded to Marshmallow. I am not sure if I am doing the right thing or not. I need your experienced advice on that.
But, I also can see there are several models of LG G3 here in US:
LG G3 D855 - International Version
LG G3 D851 - T-mobile, US
LG G3 D850 - AT&T, US
LG G3 LS990 - Sprint, US
LG G3 VS985 - Verizon, US
I would like to use it both inside and outside of US. So, if I buy the International version, will I get the 4G LTE support in US? Can I root it and install Custom ROMS in it? Because, I googled it, and I saw, Only, T-mobile version comes with Unlocked Boot-loader. Is it true?
Please, let me know, And, it would be great, if you suggest me some better place to buy this phone online. Thanks in advance.

Check gsm lte bands are listed there for each model. Although the international model has the most custom rom support and has an fm radio. And nop there are no bootloader issues with the g3.

Thanks I think I'll go with the International version.
beware of fake D855s and you will not get LTE coverage, at least with AT&T. For these reasons I went with the 851. Good luck
No LTE on the d855 in the USA. Although it really is the best version to go with, be aware of that. In the USA at least, you'll mostly run on HDSAP+ which really is fast enough for a mobile in my opinion. (Usually from 7 to 21 Mb/s)

What needs to be done when switching from VZW to TMO?

I currently have a rooted/unlocked G3 with the tethering hack on VZW and am in the process of switching to a TMO 4/150 unlimited plan. Other than swapping the sim do I need to do anything else like change to TMO firmware?
Depending on when the G5 is available it may be a moot point but I've searched and can't seem to find an answer to what I know is a very basic question.

I would NOT recommend flashing any D851 firmware to the phone. You should be able to enter T-Mobile's APN and be good. Also, the Verizon VS985 G3 supports LTE Band 4 (1700, 2100) which is what the T-Mobile D851 uses for LTE. So you might even get full data speeds.
You could also get the V10 now instead of waiting on the G5. That phone is a monster. Lol

Thanks, I was pretty sure that was the case about not trying to flash TMO specific FW.
The only possible problem may be the lack of band 12 in the G3 when I'm @ home but I'll have to wait until I do the switch to verify. As noted, I'm planning on moving the the G5 so that shouldn't be a long term problem unless my wife decides to keep her G3 as she hates changing things.
T-Mobile doesn't use band 12 even in their D851 G3. It's only capable of utilizing the following bands: 2(1900), 4(1700/2100), 7(2600), 17(700)
Band 4 is the main one used by T-Mobile for their devices.
