OnePlus One Chinese Edition CM11S LTE signal improvements? - ONE Q&A, Help & Troubleshooting

I purchased a OPO from China and flashed CM11S as soon as I got it. LTE tends to vary from place to place. I'd get a good signal outside in the city but back at home, the signal strength isn't that great.
I've done some googling and some searching on the forums, and my carrier, Optus, does support both TD-LTE and FD-LTE, however, from what I've read in a few threads, FD-LTE is roaming-only.
If I flashed CM11S, did that unlock extra bands for me, or will I have to follow the instructions from here?
Thanks

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.

Oppo r7 Plusm LTE inquiry

Hi,
I'm new to posting on xda, been using it for advice for ages but this is the first time I haven't been able to find my answer. So I'm going to apologize if I've posted this in the wrong place or done anything else incorrectly right now.
I ordered an R7 plus from Taiwan and received it a few days ago. A great phone, i am entirely in love with it. I can put up with the bits of scattered chinese in the settings as i will be flashing cyanogen as soon as it's available. My problem however lies in the connectivity. I didnt know a whole lot about wireless data before ordering the phone, but what little I did know I applied to my research and found that all three variants of the phone should work on my providers network. I have the Taiwanese variant, which does supposedly support the 2100mhz, and 2600mhz frequencies, which i believe are bands 4 and 7, anyway, these two frequencies are the frequencies my provider uses. Rogers uses FDD with 2100 being up and 2600 being down. Yet in the phone settings when selecting which LTE band 4 and 7 arent options, there's USA Band (Im unsure what this really is, I assumed it was 4 because much of the us uses band 4), 6, 33, etc. And I havent been able to get LTE to work. The APN is configured correctly. All anyone's been able to tell me is that it should work. I can provide any more information you guys need, but any help would be greatly appreciated.
Edit: For more info- My provider is Rogers, i have also tried it on Bell (still only 3g), and Wind, which works the majority of Chinese phones and it didnt even pick up their network. Any advice would be great!

I need assistance with LTE Radio

Hi, I have a 64gb OPO in USA on Straight Talk, using AT&T network. For some reason I'm not able to get an LTE signal in Burlington, Vermont area despite LTE service being available locally. As soon as I cross into New York, New Jersey, or other states I can and do receive LTE signal, so I know my device and Sim card are capable. Others have told me AT&T uses an unconventional LTE band in this area because they took over another carrier called Unicel. What I need help determining is what band they use locally and subsequently which radio I need to flash to get LTE on that band. Currently my battery drains fast constantly switching from hspa to hspa+, yet doesn't do so in other cities and states. Any help, and links are greatly appreciated.
The OPO hardware LTE bands are: 1, 3, 4, 7, 17, 38 and 40. ATT US uses bands: 2, 4, 5, 17. So, if your ATT LTE signal is on 2 or 5 you won't get LTE in that area on your OPO. The bands are a hardware limitation of the OPO and can't be unlocked, as some people have tried in this thread: http://forum.xda-developers.com/showpost.php?p=56577252&postcount=455.

T-Mobile LTE in US isn't working...ideas?

I imported the 8141 from Clove in the UK. So far, my only real issue is I have yet to see it connect to LTE. I've seen "4G" and "4G+", but no LTE...which is a problem because I can barely pick up a signal other than LTE in my area. I checked and confirmed it's using the correct APN (fast.t-mobile.com). I'm on the 110/unlimited/unlimited $30/month prepaid plan and confirmed I haven't hit the LTE cap. If I put the SIM back in my Moto X Pure/Play, it hops on LTE without a problem.
Everything I've read says the radio should support T-Mobile's frequencies. Is there another setting somewhere I need to change? Do I need to flash another region's stock ROM (and is that even possible yet)? Did I get a lemon? Do I need to hold it a certain way like whatever iPhone it was a couple years back?
Any and all suggestions are welcome.
4G+ is the UK's LTE as far as iconography is concerned. Have you done a speediest on 4G+?
I've noticed the same thing, but I (as mentioned above) thought that LTE and 4G+ were synonymous. I think the only reason to flash a region based image would be to enable radio bands that are disabled based on location (which may be in this case).
Works fine here. Lower Manhattan using same version.
4G is LTE in US.
Download LTE Discovery and you'll be able to see if it is connected to LTE or HSPA(+). Mine, also from Clove, is just fine with AT&T LTE.

You are looking at the signals wront, I'm on T-Mobile and have 4G+ as well it's the UK version of LTE. Look at my screenshot.

4G is basically the same thing as LTE in this case. 4G includes WiMax and LTE. So when you see "4G" it means you're using LTE. The same goes with 4G+ - LTE-Advanced (LTE+).
I have LTE logo on my Z3 while Z5 Premium shows 4G while using the same network.
4G is LTE in europe. We did not have that silliness that some 3,5G was called 4g. Also there is no band limitations on XZ Premium.
For app to check which band of spectrum you are connected to, please use Cellmapper app (from my signature).
If you wish to see different icon in there, you could flash Customized DE firmware which has "LTE" icon. But this has only cosmetic effect.
Instead of making a new thread, anyone knows if VoLTE works with the XZ Premium for T-Mobile?
Currently no. You need region or operator specific image Flashed (oem.sin) but there is none for XZ Premium.
But there is hope as there is t-mobile us specific modem configuration in all region images.. which will be loaded when you have correct oem image Flashed.

THREE v GIFF GAFF sims UK

Hi all,
As i can't post images yet i'll try and describe this the best i can.
I have a THREE sim that used to work in my nexus 5 till the last update, it then wouldn't get a signal so i stated using it in my moto g4, no problems.
I have since tried several different sims from vodafone/o2/giffgaff etc and they all work in the nexus 5 ( and any other mobile).
The only difference i can see is that the centre section of the THREE sim is smaller than all the others...
Has anyone else come across this ?
cheers paul
