Is it possible to edit the bands for carrier aggregation? - Nexus 6 Q&A, Help & Troubleshooting

I understand that for XT1103, the CA bands are 2+13, 2+17, 4+5, 4+13, and 4+17; for XT1100 3+5 and 3+8.
However, my country telcos only support 3+7. Is it possible to edit the CA bands for 3+7? Or is this a hardware thing? I'm using XT1100

Bands are completely hardware thing You can't change them

I see, thanks
What a waste for me, able to use LTE but not LTE-A

That is not entirely true. You can enable some bands.

Maybe ask the OP of this thread. He figured out how to add LTE band 1 to the Nexus 6.

It certainly worked fine on the Nexus 5 (enabling band 3 and 8 on the North American version). And although I haven't read much on enabling bands on the Nexus 6, I don't image it'll be any less effective.

Okay Thanks for the info btw

Nexus 5 still had some hardware restrictions for some bands. Some were possible to enable, some were not. Will require more investigation on the 805

For sure. But band 1 has already been enabled on the North American version, and @Azlun seems to be working on band 8. He hasn't mentioned anything about band 7 in his thread, and I have no idea about the carrier aggregation stuff.

Bands 3/20 on XT1060?

I will be taking my verizon XT1060 DE phone to the UK in a couple of weeks. Last time I was there I picked up a gifgaf card but didn't have time to focus on trying to use data. This time, I'd like to be able to use LTE data but most, if not all, carriers in the UK use band 3 and 20. I believe the xt1060 has bands 4 and 13 enabled. Is there any way to enable the UK bands on the phone?
Unfortunately, no. It's a hardware limitation.

Per FCC approval, the verizon version has hardware for lte bands 2/4/7/13 - Verizon
The current XT1060 rom/radio files only supports LTE Bands 4 and 13.
I have seen nothing on enabling other bands, nor have I seen the rom/radio files from other modes which are compatible to flash in order to enable any other LTE bands.
i.e. No matter what the hardware is capable of supporting, as it stands today, you are stuck with LTE Bands 4 and 13 only on the XT1060.

just to make this clear:
does the vzw xt1060 has hardware limitations for band 7 or not?
if i flash e.g. the rogers or at&t radios i will result in a phone with imei = 0 until flashing back to the vzw radios?
is the cdma&"worldphone" chipset responsible for this?
thanks in advance
You can't enable bands that aren't supported. That's it. ?

International Galaxy Note 5 N920i on US AT&T - Updates?

Hi,
If I was to pick up an international Note 5 (N920i) for use in the USA on AT&T, how would updates work? The theories I have is that either:
The device will never get updates
Samsung will release updates directly to the device
I will have to use custom ROMs for updates
Given that I will root the device (thus the reason for buying the international model), I'm assuming #3 will be the correct path. However, I understand I could run a modified kernel with the stock ROM to allow that, and there only seems to be one ROM outside of the carrier (AT&T/T-Mobile) threads. Could I use an AT&T carrier ROM?
I'm just trying to understand all my options if I walk down this path.
Thanks in advance.
You will get OTA from Samsung or you could use Smart Switch

So, if I was running a custom kernel for root, I would basically revert the kernel to stock, run the OTA or via Smart Switch, and then re-root. Sounds easy enough. Any idea what the timing is like for updates on international versions as compared to the US variants?
Thanks.

It's hard to say which International version gets updates quicker but I am sure you would have no problems beating AT&T updates.

One other question, are you using it on AT&T in the US? The N920i says it's compatibility is:
COMPATIBILITY:
2.5G (EDGE, GSM/GPRS ) MHz:850, 900, 1800, 1900
3.5G (HSPA+, UMTS/WCDMA ) MHz:850, 900, 1900, 2100
4G (LTE ) Bands:1, 2, 3, 4, 5, 7, 8, 12, 17, 18, 19, 26, 28, 40
But Droid Life indicates that AT&T also uses a 1700Mhz LTE frequency, which I thought was only T-mobile: http://www.droid-life.com/2015/02/0...sm-cdma-wcdma-lte-verizon-att-sprint-tmobile/
Looking at the wiki: https://en.wikipedia.org/wiki/Cellular_frequencies it seems that there is a seperate 1700 mhz 3G and 4G. Does that compatibility chart above indicate that since it has Band 4, it has 1700mhz 4G?
Any thoughts?

I am on AT&T. The few times I have checked I was on bands 2, 4,and 5. I have never had a problem connecting to 4G with the 920I version.

And from another perspective, I consistently connect to AT&T LTE bands 2 and 17 using the n920c (which differs from the "i" in supporting band 20 and not 28 - neither of which involves at&t.)
The only frequency from AT&T that the 'c' and 'i' models does NOT support is band 30. At the present time, I think there are only two AT&T phones supporting that band (n920a and the at&t edge+)

Assuming the N920a is the AT&T Note 5 variant, the AT&T specifications page (https://www.att.com/cellphones/sams...sku7670223?WT.srch=1&source=ECPS0000000PSM00P) does not show band 30 support?

When have you ever known at&t to be forthcoming with information?
Here's an FCC filing for the n920A showing band 30 support (as well as all the other bands supported for use in the US):
https://apps.fcc.gov/eas/GetApplicationAttachment.html?id=2679337
(The n920a may supported other bands/frequencies, but the FCC filing won't show anything that isn't tested to work in the US.)

What I just found that's VERY interesting is that the n920i has FCC filings (FCC ID: A3LSMN920I) and the AT&T variant is obviously there (with FCC ID A3LSMN920A)
However, there's no sign of an FCC ID of A3LSMN920C. That would mean that my phone, the n920c, is illegal to use or sell in the USA. oops.
That makes things interesting, doesn't it?
I've been using the N920i on AT&T now for about two weeks and my speeds are excellent.
I tested LTE the other night on the speedtest app and had 50 Mbps download, fastest I've ever tested in my area (that even includes AT&T branded phones).
So no complaints here...
I concur with HNIC215. Had my phone about 4 weeks.

After realizing that this n920c is illegal in the US, I'm in the process of sending it back to amazon (and having it replaced with an 'i' model.)

Is there something about it not being cleared by the FCC that really bothers you or is it more of a just because kind of deal?

It relates to what I do for a living... I have a significant amount of contact with the FCC. It probably would never be noticed, but if it was, I'd be out of a job and possibly fined as well. The risk is too high when I'd be perfectly legal with the 'i' model.
Being that neither band 20 nor 28 is used in the US, the radio difference won't impact usage for me.

[Q] Can I activate Nexus 6 XT1100 LTE bands?

I do not know which XT version i have i am from India and would be grateful if Band 40 could be enabled.
Is it possible?
That may sound weird , but i am not expert to this stuff thanks.
Band 40 is not available on either Nexus 6. You want a 6P for band 40.
We have an entire thread on enabling missing bands in the General subforum. However, I don't believe it can add bands neither device has.

Different Version of Oneplus 3t

So i purchase a new oneplus 3t from eBay and cant get 4g on Metropcs or H2o to work. I contacted the oneplus support chat and they told me i have a Chinese version and its not compatible with 4g in the us. Has anyone else heard this?

Yes, some models only have some 3G/4G bands on them. It's not like all models have all bands.
I don't know the model numbers by heart, but I recall there being at least 4 different.

It may be hardware related and not software related. So if it is hardware, you won't be able to get the extra bands.

India 3T - 4G/LTE not working in US

Hi,
I bought an one plus 3T in india and brought it to US. I'm getting only E not even 3G. When I enquired in T mobile/lyca store, i was told that india unlocked mobile won't support the US bands. Network upgraded. It was big surprise to me. Please suggest me how to unblock additional LTE bands in my 3T mobile.
That's not possible, you should trade your 3t A3003 for a 3t A3000 American band-unlocked model.
Check the specifications for each model under connectivity.

Wait, what?
I live in Sri Lanka (Tiny country below India) and my 3T is the Indian device. I toured Europe for 2 weeks, and I used an O2 Sim, and used LTE in Europe for the whole time I was there. Have you tried going to Settings, and selecting "LTE/3G Only"? That may fix your issue.
I swear, there should be no issue with the bands.

Compatibility of phones with the cell networks in the US are a total pain in the you-know-what. We have 4 different major carriers, all using different bands (a little bit of band sharing, but most completely different) for 3G and LTE (GSM is a little more standardized thankfully). Basically, as a general rule if a device not intended/designed to work on US (and depends on which exact US carrier), you are probably going to run into some incompatibilities (no 3G or no LTE, or limited connectivity).

Talk about synchronicity eh? But do the difference in bands give any speed differences, or call clarity? In the blind about these stuff, coming from a country that has only one carrier out of five who is still beta testing VoLTE.

Not an expert, and had to Google that. From what I'm reading, lower frequency (MHz) has better penetration (through buildings, etc.) while higher frequency bands have higher data capacity.
There are steps on how to unlock additional bands. There are like 50 steps. I dont remember where I've seen it but if you google how to unlock bands on OnePlus you will find it. Also try to flash Oxygen OS from US web site which I see no reason to work but just a suggestion lol

There are no steps at all. You cannot "unlock" bands, as they're hardware related. There's no way to switch bands out of the blue.

At one time that was true. But for Qualcomm SoCs, the band support stopped being set in hardware (at least for the most part) some 3 years ago with Snapdragon 801 (or maybe earlier, but definitely with 801). Support for all or most bands (might be some exceptions) used worldwide is there, but the specific bands are enabled in firmware.
https://www.qualcomm.com/products/rf
That said, enabling bands is a long process as noted; and has the risk of resulting in a radio brick. So it's best to buy the correct region version OP3T (which supports the needed bands out of the box) when possible.

Why aren't all bands just enabled by default then? I don't understand why there are different models for different regions.
I have a US OP3T and I'm visiting India. It''s working with Jio in India (although it supports only only of the 3 bands used by Jio) but VoLTE doesn't work for some reason.
