From what I read in this thread I was also leaning towards Band 2 most likely not working. Which really sucks, as I purchased the ONO to replace my N4 because the ONO had LTE support. I checked the frequency, but did not verify the band. It is my understanding that the LTE is replacing the EDGE network on T-Mobile, is this correct? I am afraid of sticking with this awesome phone and loosing all connectivity at my job and most of my drive to my job. I live in Oklahoma and have great band 4 LTE in the city but drive out of the city for work where I only have EDGE. It is looking more and more like I will just have to sell the phone and try to break even.

In CM12 "S" (Cyanogen OS 12.0) isn't working the diag mode, and cannot disable MTP.

Damn! Any ideas?
[ONE General] Valicore:
Honestly the main thing I'd worry about with this phone is band 12 support, and unfortunately we have no conclusive evidence one way or the other about whether or not that works. I'm hopeful that it will work but there's no way to be sure. In terms of the EDGE to LTE transition on band 2, it is happening, but sites that take that upgrade will also eventually be upgraded to band 4 and band 12 LTE, so it's not as huge a deal as it seems, at least not yet, to not have band 2.

Thanks for the tutorial! Would this work on a LG G3? I got the European version D855 and want to open some common US LTE bands. Do you think it is safe to try this method?

change the bands in settings?

Great work.

One thing I dont understand - should I change the bands in the service menu to my country?

I'm on T-Mobile in California, US.

Should I go to the service menu and change in the GSM/UMTS menu to USA bands? Or leave it automatically?

BTW - Now i notice the 12S doesn't have the automatic option at all...

Thanks!
[ONE General] NaterTots:
I wasn't able to get Band 2 lte to work. There is an area near me that my N5 gets LTE, which I assume is Band 2, but the OPO is still on Edge.

This is a rural area and it seems that the edge is being moved to Band 2 lte. I belive that is also the only lte band difference between the OPO and the N5.

After I was in the area I went home and confirmed that all of my LTE settings were still where I put them and they are.

I was really hoping to get Band 2. If T-Mo does move everyone to Band 4 from Band 2 that would be great, but I've not read anything about that. I've only seen it said that Edge was going to Band 2.

I have found now though that my phone has a hard time reconnecting to the network after being someplace with no service for an extended period of time. I'll be back in a very strong service area and it won't reconnect until I reboot it. I'm not sure if this has to do with the settings or is a problem from CM 12 4/07 nightly.

Service issues COS12?

Hey all,

Since I upgraded to COS12 I've been having issues with signal, primarily when I go from wifi with no signal to an environment with signal, I have to restart my phone for it to get signal. Has anyone else had a similar issue, is it related to this alteration or is it a COS12 issue?

Thanks

Yes. unlocked 1+1 doesn't seems to get any LTE signal in LTE20 only zone so it's very likely a lack of antenna since chip does support band 20.

[ONE General] abs0lut3z33r0:
1. Download the rmt_storage patch and put it in your phone storage's root.

2. reboot your phone in recovery mode, install the rmt_storage patch then reboot in system mode aka normal mode. (when phone start, you won't have any signal for a min or two so don't panic)

3. Follow OP's steps from 1 to 9 (we need QPST configuration's server configured and active

What is the rmt_storage for ? Is there an undo patch for it? I installed it on my HTC One e8 not it restarts every 30 seconds. I accidently clicked on USA band in HTC band selection menu so i following this thread to fix the issue . Any help would be appreciated , i am currently travelling to china and my twrp backup is at home .
[ONE General] Marcianisto:
I can confirm that. But I can't search for networks manually. Throws "Error searching for network". :(

I'll try flashing 11S modem.
[ONE General] Albirew:
I don't believe root is needed but you might need to change recovery for something with backup / install functions like TWRP

rmt_storage patch is needed on 1+1 phones only (to prevent NV recovery on next boot) and is very likely different for every phone.

Your only hope is to download and fastboot flash modem

KK modems on LP roms = brick

I recommend a clean reflash of the rom.
[ONE General] maskelisuvari:
Thats not correct, i have been using kk modem on lp os for awhile,no bricks.
[ONE General] Marcianisto:
Yep. Flashed CM11S (XNPH44S), worked in CM12.1 but same problem, Error while searching networks. (I can get coverage but only with Automatic Network).

Reflashed the ROM and the same. For me isn't a problem, as I'm not travelling, but for roaming it could be.

EDIT: It happen only when WCDMA is enabled. Only when using Japan UMTS bands.
[ONE General] the1kingbob:
Went ahead and rooted device then installed TWRP. Gone through the amended guide, but stuck at step 9 of the original guide portion. Under 'Ports' tab in QPST Configuration it finds my device on COM3, but under the Phone it states "No Phone". When going to "Active Phones" tab it states Unknown under Phone, No ESN under ESN, and Unknown under Banner. When going over to QXDM Pro, I can't really do anything.

I am using International ONO 64GB. Rooted w/out su on CM 12.0 -YNG1TAS0YL. I can test channel 2 LTE at my work... if I can get this unlocked. Any guidance would be great.
[ONE General] Marcianisto:
Had same problem in CM OS 12.0-YNG1TAS0YL ... Diag is locked. In CM12.1 (Nightly 18/04) worked w/o problems.

Try flashing another ROM (eg, CM12 (Nightly), CM12.1, or CM11S. OXYGENOS DOESN'T WORK), write NV and then flash again CyanogenOS 12-YNG1TAS0YL. At least for me, any ROM I flashed after writing, didn't replace my NV settings.
[ONE General] bboywins:
uninstall rmt_storage patch?

I tried this experiment, and have decided I'd like to revert my phone back. I didn't see instructions on how to remove the rmt_storage patch. Can anyone provide guidance to do so?
[ONE General] the1kingbob:
Ended up having to install PA (kept getting 404 not found when trying to dl CM12s). I was then able to follow the listed instructions. I was, however, not able to connect to LTE band 2. I tried changing the device to the different bands (AUS2, EURO, USA, JAPAN, and AUS) without success. I was only able to secure a Edge connection when on USA. Is there something else I need to do try? I wasn't sure how to force LTE 2.

Edit: If band 2 and 12 are dead, what device should one look to? The ONO offers so much hardware for the money, just blows that it does not support T-Mobile's plans well.
[ONE General] Coug76:
Has band 12 been definitively been written off? I think the jury is still out at this juncture.

[ONE General] xavierpitz:
When I disable MTP it disables me the ADB...

And when it is disabled I cant enable the ADB anymore (grayed out) because it is complaining about the fact that the OPO is in charge mode.

I'm running cm-12.1-20150502-NIGHTLY-bacon.

Is it a cm 12.1 limitation or do I do something wrong ?

When I try to perform "setprop sys.usb.config diag,adb"... well then there's no additional devices in the Device Manager.

I'm pretty sure it comes from the fact that I was not able to disable MTP while enabling ADB at the same time...

Any trick for me ?
[ONE General] mojo-chan:
Is there any fix for stock Lollipop ROMs yet? I'm in Japan and can't get on DOCOMO with a rented SIM (no LTE) so unless I flash a different ROM I'm screwed...
[ONE General] mojo-chan:
So I downgraded to 4.4.4 and did the hack, but still can't get DOCOMO working. None of the available bands in the Phone Info screen list 1700 and 2100, the two that they use. Long story short I have a very limited rental SIM and can't use other bands. My old Galaxy S3 was fine but I can't get the OnePlus One to work at all. I simply can't see any networks that the SIM is allowed to use.

Anyone know how to get 1700 and 2100 bands?
[ONE General] Albirew:
OPO support natively LTE Bands 1/3/4/7/17/38/40

DOCOMO's LTE bands are 800 (band 19) 1500 (band 21) 1800 (band 3) and 2100 (band 1).

So 2100 is supported natively by 1+1 and 1700 (band 9) is a subset of band 3 and should be supported natively too.
[ONE General] mojo-chan:
Thanks, but I can't use LTE. I need 3G, the SIM won't allow anything else. It's a rental.

[ONE General] mojo-chan:
I couldn't get it to work on Docomo. I switched to a portable wifi hotspot and don't want to screw about with my phone any more, after getting a fright from a bootloop after trying to go from 4.4.4 back to my 5.0 backup. It was okay in the end but...

Band 12 Coverage Map: http://www.spectrumgateway.com/t-mobile-700a-spectrum
[ONE General] Albirew:
How to know if band 12 is available:

1) check your operator coverage map to see if there is a place with band 12 only.

2) go there and check if your phone connect on LTE (may not be instant)

3) report any attempt here along with your provider, the place you tried and your result.

[ONE General] simonsickle:
I can confirm that the LTE Band 2 does not work on the OnePlus One. I am in a T-mobile refarmed area which utilizes band 2 LTE. My nexus 5 will show LTE signal while my OnePlus will sit on Edge. All information stuck when it was written as well, so theoretically all the bands are enabled as well.
[ONE General] Albirew:
well, that's kind of extreme but still feasable, yes. But one need to check LTE12 coverage before doing this... It would be a waste to do it in an area with no LTE12 coverage in the first place (^_^; )

The International model (NV untouched) get the service without issues, but the Chinese one with the bands unlocked can't.

[ONE General] idoit:
Important question:

With this value for NV #1877, you have checked band class "60 Reserved for BC10-1700" and "61 XI - 1500". If I select these two bands, my phone (Mega 6.3") loses even GSM signal let alone LTE! Can you tell me why this happens? If I de-select these two, it works charmingly.

I am using QXDM to write NV. For LTE bands (concerning NV #6828), say I want to enable LTE band 41 on top of what is already in Original Values for Intl 1+1 (just as an example). The original value as mentioned in that main post was 1010000000000000000000010000000001001101 (decimal 687194832973). So should I just add a 1 to position 41 which yields to: 11010000000000000000000010000000001001101

Also, yes BC10 is bit 14 BUT that is CDMA-2 and we were told to be careful changing values other than WCDMA and GSM. That's why I asked that question above. As I said, if I enable those two bits (bit 60 and 61), my signal is gone and phone goes for reboot loop.

I still appreciate if anyone can help answer my above question.

A few more questions:

1. Is there any app that can tell what bands a phone DOES have? I'm not asking for the band which it is operating currently, but all supported by hardware...

2. Does anyone know about bits 32 to 41 that are for WLAN and bits titles under Etc-1 and Etc-2?

Well, we can enable them via NV1877 but whether it's ACTUALLY enabled is another story. My chipset is msm8930ab and if this is reliable, it should be supported by modem! ?

Thank you again.
[ONE General] Albirew:
Haha! I'm glad you found it usefull (and hopefully worth the beers I drank ;) )

Actually both: hardware limitations as lack of antennas for some specific bands and software limitations because of laws in China and some other things of the same ilk.

But because chinese 1+1 was made mainly for chinese market, there are some more hardware limitations as far as I saw from the comments.
[ONE General] Valicore:
So I was in traffic in LA today near USC and I got these glimpses of band 12 - it was bouncing between band 12 and band 4 so I didn't get a chance to do a speed test, but it was reported as band 12 in LTE Discovery and SignalCheck Pro - seems like a somewhat legit indication that band 12 is functioning on the phone right?
[ONE General] Coug76:
We have seen hopeful signs of band 12 before (that were unfortunately incorrect) while using the LTE discovery app. The app has been improved.

The apps mechanism for reporting bands is based on data from phones that actually report band data and correlate those to tower identifying data. It is not clear if you are seeing actual band 12 from those images. It certainly warrants seeing of someone can correlate data from a band reporting phone (Note 4, S6, Nexus 6) to the tower GCI info. That would be sweet.
[ONE General] Valicore:
So both LTE Discovery and SignalCheck Pro use the same method for determining band on non band reporting phones? I was hoping it would be more conclusive since I had BOTH of those apps open and reporting band 12.
[ONE General] Coug76:
That is what the dev who built LTE Discovery mentioned (IIRC).

Regards
[ONE General] Valicore:
You might have gotten the Chinese version if you didn't order it directly from OnePlus. The Chinese version doesn't work on those frequencies. Otherwise LTE should work out of the box with the OPO if you have APN settings properly configured.

How can i know if have chinese version or inter version ?

I traveled to usa and works very well with tmobile lte services

Another question friend, do you reocmend me to flash to oxygen ?
[ONE General] Valicore:
If it worked on T-Mobile in the US it is the international version and should be working in Argentina. Who is your provider? There are a couple of possible issues. You might need a different APN to access LTE. You also might need to update your SIM card, some companies use different, newer LTE compatible SIM cards and you have to switch out your current one for a newer one. The best way to test it is if you have a phone that is working with LTE and then you take the SIM card from there and try it in your phone. Also of course you need to make sure LTE is enabled on your account.

About Oxygen OS, for now I'm sticking with Cyanogen. Let us know if you get your LTE working.
[ONE General] tatomenem:
Yes worked with T-mobile perfect !. My provider is Claro Argentina (band 4 and band 17). I updated my sim card and the apn is the same.
