I'm sure it's possible my question is why would you want to.

I'm researching how the LTE radios behave on the TMobile firmware as opposed to the stock firmware. Mine sticks to band 66 TMobile at home all the time, whereas my other T mobile branded devices switch bands depending on what room in the house I am at.

I've noticed this as well on DP4. As for your original question, if a TMo variant can flash the International software via MSM tool, I don't see why the International variant can't flash the TMo software using the same tool. You'll obviously lose one SIM slot, though.

I'm on the stock 9.5.11
So you noticed that the LTE bands don't switch much ?

I live in Memphis with plenty of cell towers around me and they're 99% of the time locked on to Band 66. I've only occasionally seen Band 2. They said completion was supposed to be done last year, but I've never seen Band 71. I don't know whether it's a DP4 false reading or not but while taking screenies for this post, I just got my best signal strength ever at -70 dBm

At my home location I primarily have three available LTE bands , band 12, 2 and 66 central Florida. On my Samsung device which is TMobile version it switches often between those bands. However on my dm1917 device it sticks on band 66 indefinitely at my home.
Signal strength on all the above bands range from -90 to -119db at my home.

China OPO in Canada (Toronto)

Hi all, it's been a while since I was last on XDA.
I recently received a One Plus One in Hong Kong and I am unable to tell if I got the China or the International Version.
I do not receive LTE in uptown Toronto but I do get LTE in downtown. This leads me to suspect this is a China device as it doesn't support band 7 lte.
I am currently using Virgin Mobile (Bell network) and I think Bell uses Band 4 and 7 LTE (Please correct if I am wrong).
Is there anyway I can tweak the phone software wise to enable LTE on the network? it really bothers me sometimes when I can't load a page instantly and instead have to wait for a good 8-10 seconds.
Thank you and happy holidays!
There's one very easy way to tell which version you have, the international version has Cyanogen branding on the back and the Chinese version doesn't.

Unfortunately, mine doesn't have the cm branding on it
Is there a way to enable those lte bands still?

It is IMPOSSIBLE that you get LTE on the Chinese version of the phone, you can't get it in downtown and not in uptown... You have it or you don't

That's really weird, I have the LTE signal in downtown but not uptown!
When I was using the HTC One, I was able to get LTE both down and uptown too!
Bump, thanks.

NOTE: I am on Rogers Wireless.
I get LTE in Markham, Richmond Hill (A lot of H+, little LTE rates compared to downtown), Mississauga (Also a little, but a lot of H+) and Downtown (97% LTE rates)

Flash the latest 44S or 38R modems. Get out of the stock ColorOS modem.

This is false information, they are both the same device. The modem just needs to be flashed out of the stock ColorOS modem.

I understand, I was confused before when I had 25R modem installed, I didn't get LTE much, and I switched between G, H and H+ when I was riding the GO Train.
There's no difference between the China and International models, except the Cyanogen branding. Just need to get out of ColorOS modem.
I can confirm this as I have a Black China Model OnePlus One, and the Limited Edition OnePlus One Bamboo (which is only available in China). I'm from Hong Kong too so I handed over 4 OnePlus Ones to my friends in Toronto, from Hong Kong.
That is very good news to me. I will search a bit regarding that modem.
Thank you!

Good luck man, hope you get better signal!
Just fyi, when I ran ColorOS modem, I got worse signal than CM11 modems, but no modem is the best, you should try a few from this thread:
http://forum.xda-developers.com/oneplus-one/general/ref-oneplus-one-modem-collection-t2858734
You can see a chart to see the difference between the modem versions, as they all report the same values in About Phone.

[Q] 920i vs 920f?

So does anyone know the difference between these two models? I live in the US using straight talk on AT&T's network. From what I can tell, they both should work, but I am not sure if there is any difference I should be aware of before buying the phone.

I have the G920i that I'm using on cricket (cricket uses att bands) and it works perfectly with LTE. I'm not sure about the 920F but I know that the f is the global unlocked version whereas the I is also unlocked but for selected regions.

How does it work in areas where LTE is not available, i.e. on 3G and HSPA networks? I live in an area where half my day is spent on the fringe of LTE service and the other half in.

Well just like US carrier phones, you'll get LTE signal when you get LTE signal and you'll fall to HSPA+ or 3g when that is the signal you get.

I'm asking more along the lines of can the phone receive the 3G bands in the area? I was wondering if the phone actually could receive what was being broadcast.

That I don't know. You gotta check the bands with your phone and carrier.

My G920I does on AT&T. I've seen it go all the way down to EDGE because I have really bad signal at my house.
I can also confirm that the 920i works fine on AT&T. I have seen it go from Edge to LTE and everything in between.

Anyone try to unlock the 4g bands with success?

I love the phone and the size but only getting H+ sucks. Has anyone tried to unlock the 4g bands?

I tried. Not possible. I got all the way to putting in the new values in the phone, but when you reboot it they go back to default. There is a fail safe in the kernel preventing it. need a custom kernel to do it successfully. Here is the thread that I was discussing back and forth with another member:

It all depends on the band the carrier is using. The phone doesn't have all LTE/4G bands unlocked. So if your carrier is using a band that is available on the phone then you are golden. For me the only band the phone has unlocked that AT&T uses for LTE is band 5. Half my city is band 5, and the other half is 2 and 17. So in the band 5 areas I have 4G, and in the 2 and 17 areas I have HSPA+

The LTE bands in the U.S. are blocked. Back in the day we had same issue with the original Samsung Note 1 - in was only built originally for ATT. Eventually folks built roms/kernels that did the trick on T-MO.
So here's to hoping the same thing happens w/ our ZF3ultra

Hi,
Could anyone provide "rfnv" files of Asus ZenFone 3 Ultra?
I trying unlock bands for Leeco Le 2 X520 so "rfnv" files of Asus ZenFone 3 Ultra will help me a lot.
Thank you for your attention.

I have the HTC u11 running the viperu 2.1 rooted by magisk 15.1. I was wondering how to unlock the 2 and 4 bands. I installed network guru but didn't pay for the full features. When I look at the lte bands I only see the 13 band.
Thanks in advance for any help.

Try three dots right corner( lock bands.)

Lock bands doesn't show lte. I assume that band would be part of the full version.

Honestly I could not figure it out either. I just hit ok then noticed it worked. Most times uses band 4 sometimes 2 or 13 depending on my location.
You'll want to go to setting, experimental, then LTE append. Put in 2#4#13. Then go back to lock bands and make sure they are selected.

Thanks I now see the other lte bands.
I know you're using Viper, but the latest stock Oreo build fixed the band issue. I now connect to bands 2,4 and 13. Cheers...

Surprise! I just saw LTE Band 5 for the very first time today.
Didn't last long before going to #4.
Was located in Orange County, CA.

Thanks. My LTE voice and broadband service cut out a few days ago.
Locking down bands 2 and 4 didn't restore it, but including band 5 did.
I'm still running marshmellow so I don't expect most people will have this issue.

Tmobile LTE Bands

Will they support T-Mobile LTE band 71
Yea, I'm 99% sure. Since it will have Snapdragon 845 like the Galaxy S9- that supports b71. We should also see VoLTE and WiFi calling like in all other OnePlus phones.
I read this on another site. It doesn't looked like it

That references the OnePlus 5T. I think they have just taken last year's model and updated it as a place holder. I don't think it's official information.

Like how @holz75 mentioned, check the spec in Oneplus website.
Does anyone know if it will support dual VoLTE standby for 2 sims?
This is from OnePlus website. Click on the Check Carrier Compatability link
Came here to ask a similar question. Now that the details and specs have all been released... I've always had carrier phones, currently with Tmobile. Using the op6 in north america(florida) will this phone get the same kind of reception and network speeds as a carrier branded phone would, like an s9 or lg bought from a tmobile store?
Thanks

It should be very comparable. 4x4 MIMO, with 256 QAM and cat 16 LTE. I'm in North Florida too and the OP5 had good reception here.
Anyone tested to see if we can connect to band 71 on T-Mobile
http://www.spectrumgateway.com/600-mhz-spectrum#phones
T-mobile Band 71. One plus 6 listed.
Everything related to Band 71 from Tmobile is listed here.

I'm in PA but I can tell you my wife has an s9+ and although her reception is fine, mines better on the op6 on metro (which is T-Mobile). As for band 71, I don't have much of that deployed near me but I've used most other bands listed on oneplus' website so I think it'll work fine.

Why does this matter? I'm on T-Mobile and OnePlus 6 works like a charm. In full bar areas, I'm getting 100 mbps
