Add LTE Band 3 to OP3?

Hi guys, so after a bit of research I found that you can add/enable bands on the OP1 as shown here
http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031
and Here
http://forum.xda-developers.com/showpost.php?p=56577252&postcount=455
My question is can I add LTE band 3 to my OP3 A3000?
Mine currently supports:
North America model(A3000)
FDD-LTE: Bands 1/2/4/5/7/12/17/30
The other models support:
Europe / Asia model
FDD-LTE: Bands 1/3/5/7/8/20
TDD-LTE: Bands 38/40
China model
FDD-LTE : Bands 1/3/7
TDD-LTE: Bands 38/39/40/41
If anyone has done this or attempted to do this please let me know

Looking for the same information.

Also been searching for this. Found another thread which says hopefully in the next month or two it will be looked into.

Could this even be possible? Aren't bands hardware dependant?

Its possible to add bands in Qualcomm devices .. i added h+ band in my Xiaomi mi note 1year ago. (Snapdragon 801) ... Somewhere in xda exist a tutorial to add bands in xiaomi mi note pro. Try the steps in oneplus ... But make sure you nandroid backup and EFS backup.

This is what I'd assume as well, but it looks like some have been successful in the past with Oneplus devices. Especially since Oneplus' response to the band omissions seemed a bit vague IMO.

Any updates?
I have a A3000 US model (Does not support LTE band 3)
AND NOW
I have just got a A3000 HK model (For my dad) (support's LTE band 3)
and the "about phone" part is identical apart from the baseband version.
Is there any way to tell them apart. And does this mean I can somehow unlock LTE band 3 on my US version of the OP3?
If there was someway to backup the basband and restore it on on my US OP3 that would also be great!

The HK model is A3003 so you actually have a China model.

AFAIK there isn't yet a way, but I would suggest to follow the most active thread on the subject:
http://forum.xda-developers.com/oneplus-3/help/unlocking-lte-bands-t3425871/page6
Hopefully something will come up..

Can this work on all carriers? Whether in North America or over seeas?

I've got OP3T A3000, tried multiple files and instructions to unlock LTE band 3 on it, no luck so far. Downgraded to Nougat, Oreo, different zip files, qcn files, hex editing stuff, most of these process went error free with still no band 3.

Pixel LTE bands - North America and Rest of the world

Hi there,
Looking at Google Pixels page one can see that there is two versions of the product: NA and RoW.
Question is: is there any chance of buying a RoW version in US? Has anyone ever managed to buy the past Nexus International Versions in US before?
Thanks all and regards

Took me a few seconds to figure out what RoW means. I'd like to know this too.

In regards to the N6p I tried to buy an Intl version from the US but it wasn't available.
Had to be bought from Intl market like EU or the Middle East..

Is there any difference in the UAE? Both versions support LTE Band 3 and UMTS Band 1. Should work fine in the UAE.
I'm using US 6P which also supports LTE B3 and have not had any issues at all.

To my understanding of supported LTE, UMTS, and GSM frequencies both Pixel Variants will work in UAE but Carrier Aggregation will probably not work. Not sure if the operators in the UAE support CA (yet) but if/ when they do this will probably something that wouldn't work on the NA variant. The only combination supported by the device for UAE bands is B7+B7, which may or may not work.
Whether this is a deal breaker or not is up to you to decide.

Won't work. There are two different version. One that supports international LTE bands and one that supports the bands in the USA. Just like the Nexus 6, 5x and 6P. If you buy the Pixel in the USA you'd only be able to use 3g speeds in Europe, band 7 (1800mhz) being the only exception.
In short, should you buy the pixel phone in the USA you won't have 4G in Europe and other countries that use the same bands.

Same with me. Worse than that, Google does not sell then in my country. So, unfortunately, I may have to buy outside US as well again.

Now that the pixel is out i can't seem to find anything online (N6p H1512 64/128gb) that comes with a warranty, if you do come across one that includes warranty please dm me.
I found out the warranty over here is handled by the retailers and is not international (covered by Google/Huawei).

I am also looking at this and cannot understand the CA limitations on the US device. Unless I am mistaken the Snapdragon X12 modem supports all combinations of supported frequencies. Yet the phones have different combinations for some reason. I do not know if Google is limiting this via software. Any thoughts?

How comes? Both NA & RoW Pixel's tech specs show bands 3 and 20 (beside the band 7 & others) which are the most common bands used in Europe for LTE, so I can't see why the NA model won't have 4G in Europe... Can you please explain?

Lots of overlap
There appears to be quite significant overlap, with the NA version supporting all or almost all LTE bands in most European countries and in many non-European countries as well (including all LTE bands in UAE):
NA version: frequencycheck.com/compatibility/GPQkJ/google-pixel-xl-phone-nexus-m1-td-lte-na-128gb-htc-marlin/countries
RoW version: frequencycheck.com/compatibility/vWPw8/google-pixel-xl-phone-nexus-m1-global-td-lte-128gb-htc-marlin/countries
---------- Post added at 07:15 ---------- Previous post was at 06:52 ----------
Hmm... just noticed that a few European countries that FrequencyCheck lists the NA version as having only partial LTE coverage for are because the site considers the NA version not to support band 8. But, according to Google's own spec page (madeby.google.com/phone/specs/ > Telephony), both the NA and RoW versions support B8. No idea if FrequencyCheck is a generally reliable source of info, as I just discovered the site a few minutes ago. I hope Google's listing for their own phone is correct, but the fact that B8 isn't included anywhere in the LTE 2xCA and 3xCA breakdowns for the NA version as it is for the RoW version makes me wonder...

Yes, the main European LTE bands are 3, 7 and 20, so it doesn't matter which version you have as both support all these bands. scandalousk is wrong.

Partially, it'll support 4G. But it won't support LTE-Advanced (4g+)

It'll support LTE, but won't support LTE Carrier Aggregation. LTE-Advanced is more than just Carrier Aggregation.

Euro Rom - missing LTE band 3

Hello guys
i got the OP3 A3000. i got mine from the official website and its the American version.
ilive in Israel, and there for my device wont have a LTE band #3 like the European versions come with.
my question is, if ill install a Euro rom..would it include the missing LTE band?
* is the anyway other way to pass this issue or installing the missing band ?
thanks in advance.
Eli

Nope. The bands are defined outside of the rom, I'd assume in the modem configuration.

Unless you have the encryption keys to program the baseband...
There's a thread here where people have been trying to change bands without success.

My friend you should check if the phone has the band you need before you buy the phone.
A3000 model it's also for China region.

tl;dr - bands can't be changed

One version for US and Rest-of-World this year？

We know 1st gen Pixel has two version: NA and RoW(Rest of world) , but i found UK and AU store website which should be the "RoW version" has exactly the same radio band support as as US store version .
So this year Pixel 2 seems only have one version for all ? or is it just wrong info on the spec page? I'm confused.

It's the same version sold worldwide.

its good if it is, as then everyone gets all the bands so you can travel anywhere with the phone. seems only difference will be project-fi in the US using an esim.

It's cheaper for the to make only one version for everyone
Sent from my Nexus 9 using Tapatalk

Yes, of course it's cheaper to make only one version, but so far no company managed to integrate support for 21 LTE bands and all possible carrier aggregation combinations used in US/EU/Asia.
Not even Apple (who like to save cost more than any other company I have dealt with).
It all results in extra antennas and radio front-end components that need extra space and cost extra money.
Congratulations to Google/Qualcomm/LG/HTC if they actually managed it this time

Last year I bought the US version which didn't work well with my China Telecom... I'm glad this year they only make one model to fit all...

Yep, one stop international device shopping is the best way to go...

The Pixel 2 XL supports 4G pretty much anywhere in the world.
Carrier-aggregation might be another story though, the USA and EU models might differ in what bands they can combine.
Google hasn't mentioned what bands are supported for C-A so we don't know yet. If anyone was thinking about getting the phone in the USA I'd hold of for just a bit until it's been clarified.

I live in Japan and was waiting for Pixel 2 for ages, was super disappointed that they are not only failing to sell this here, but didn't include the appropriate bands for Japan. Bands 1/3 will work and you'll just have **** coverage if you're in a basement or out in the country, which is good enough I guess for a tourist. I ended up buying last year's Pixel after waiting a year for the 2.
I just came across this today after digging for info on the Pixel v1 I just got. Not sure if I'll be more or less annoyed if I find out the Pixel 2 really does secretly support other bands.
Edit: Bands 19 & 21 are what I need to full coverage.

Thanks - but I know what bands I need and I know what the Google reports the phone as having.
The issue is there's a dependency between what GCF reports and what Google claims.

Yes that seems to be a possibility. So, they may be able to be enabled with a different modem firmware if so, though I don't want to get back into the constantly fighting to keep my phone updated with unsupported software.

Sadly,they drop the LTE band39 support this year, Living in China , and this is one of the bands China Mobile use in my city. B3/B38/B40/B41 are the other bands China Mobile using. So it should be some coverage problem especially in tunnel or subway.

Clarity needed: changing EU phone to NA ROM, does it enable all NA LTE band

I can get my hands on a EU OnePlus 7t or 8 Pro but I want the NA LTE bands for Canada fully functional. I can see that you can switch the ROM, but I just want to confirm if that will allow me to have all the band's listed on their model?
If possible, I'd like to switch and not keep the phone rooted so I can use all apps normally. This possible? Thanks

Afaik the ROM doesn't limit the bands. Imagine buying an unlocked device and travelling abroad. It wouldn't make sense to limit the functionality with software.
However, the hardware as limiting factor is a cost and compatibility choice. Hence, changing the ROM will not make your device compatible to more LTE bands.

What someone needs to do is flash an NA (North American) image (for a HD1905 HW variant) to an EU Oneplus 7T (HD1903 HW variant) and actually check whether band 71 works.
And I mean you need to do this with the MSM-tool. You may have to flash the modem partition too I am not entirely certain the MSM-tool does that.
But no-one seems to have done this as far as I know. For the techy users on here this should not be very hard.

It depends if the EU version came with the band in the first place

Firmware does Indeed control the band's. But it is very difficult to manipulate as an end-user.
Phone manufacturers have to go through testing certifications in countries to be allowed to enable certain band's for their product to function there. They keep it well hidden from users like us.
That being said, I don't believe this works with the 7T (or any OnePlus phone).

Most likely chip specific. If the modem chip maker included ALL the bands on one chip, what fun would that be.
By making chips with different bands, they can charge multiple prices, depending on the market, and, phone makers
can sell different phones to different markets instead of a one size fits all approach. $$$$
