Hi I recently purchased the GM1910 model which is the Chinese model and it's on its way in the mail right now was curious about if it was possible to add Band 71 to the phone. I plan on rooting and using a custom rom already. I have TMobile which I know uses the Band 71. Would just flashing NA build add it or is there more to it.
I'm curious to find out this as well

From what I heard I don't know for sure. But people said the hardware itself is different. So I don't know if you can just flash it.
Your correct, it's hardware and new radio bands can't be added...
I've heard that the phones are identical. They are only switched off bands. Older OnePlus phones were able to unlock extra bands that were locked based on the region. The band support hardware wise is built into the modem. They are disabled by software.
Obviously they have to have antennas for the radio frequencies, but the hardware seems to be the same amongst gm1910 and gm1917. I wonder if someone posed a modem backup from a gm1917 and you flashed on a gm1910 it change the modem firmware to the US.
I'm willing to try this if someone posts the .zip from a gm1917
I want to unlock bands 46 and 48 for Verizon since it's LAA and CBRS/3.5ghz LTE

First unfortunately it's not just one version for all the carriers as some had suggested. The GSM providers phones do not support CDMA. The T-Mobile version is the only one with the new band 66 LTE. The AT&T version is the only one that supports band 30 (the fastest band in my area)

Seems it had them all. I'm curious as to why the att version is. Band 17 if att themselves use the 17 in many places. It's actually one of the main bands of att and they don't have it showing

Band 12 includes band 17. If the phone truly doesn't support band 17, then I suspect that AT&T advertises the band as 12 and 17 to support it.
Guys check this eBay listing, there's something funny about it, 232298704354
Selling cheaper, one unit, faster than official shipping.
The seller feed back is off from picture to details of feedback and also the items sold are entirely different than phones.
Think it's a hacked account?

So what it seems like to me (im not including sprint nor did I even pay attention to it) is that the Verizon model should work great with both AT&T and Tmobile if one wanted to switch. Looks like the verizon model would be the closes to the factory unlocked model, even more so if they really dont have any Verizon branding on them. But, what is 3G TD-SCDMA that is on the GSM models?
It appears that Samsung's website is showing the same unlocked model for all carriers (G950U*), although I'm not sure why the LTE bands supported are listed (slightly) differently for each carrier. Confusingly, this is a different model than the phones being sold directly by each carrier (G950P for Sprint, G950A for AT&T, G950V for Verizon, G950T for T-Mobile). You can see that that LTE bands supported by those models are different that the G950U as well (the carrier-specific versions seem to have a subset of the LTE bands supported by the unlocked version). I was not able to locate a spec sheet for the G950P.

The phones I ordered from samsung are not the same as I would have gotten from the carriers directly? I'm sorry but i think it's you that is confused.

It's the same model phone but with different FW. It is possible that specific carrier models only support their own network bands thru FW. In the past, the Samsung would actually have different radio and antenna hardware in the phones.
Given the proper FW I believe the s8 series will function identically no matter which carrier model is used provided the SIM is unlocked.
My 2 cents

That's exactly how the US S7 variants were, only difference was the firmware installed. I'm hoping for the same.
I purchased a Honor View 10 from Alibaba a couple months back with the international build (BKL-L09 8.0.0.131 C636) installed on it. I however live in Canada and the LTE bands installed in this version don't work in Canada. I just saw they finally released the View 10 a couple of days ago in the US and the band's will on the US version will have the LTE bands that will also work in Canada. My question is what is the US model of the View 10 and is it possible to unlock the other LTE bands?

I think you need rebrand your device to a US variant
I emailed Funky Huawei and they said rebranding will not change LTE bands. Unless of course they are wrong...
really? It's bad news for me. I have Chinese version view 10 already.

Rebranding will not change LTE bands!
A phone's bands are physical. Just take a look at one of jerryrigeverything's phone teardown videos and try to spot a long wire(s) going around the inside of the device.

Actually the LTE bands can be unlocked but not via rebranding but changing (or updating) the kernel. The bands are only locked to a specific region via software which is related to the kernel of the device. Rebranding only helps with receiving updates for a certain region but you gotta change the kernel.

I really don't know if it would be just something in kernel, but until EU version isn't on 8.1 we cant test or propperly compare kernel source.
We know Kirin 970 is capable for all frequency, because P20 is out only as one version for all markets,or at least for EU/US
Maybe with this way it is possible to rebrand from US to EU and get LTE bands

It's in the modem.. That's what dictates what bands your radio received.
It's that easy on Samsung.. It's that way here.
Wee used to flash different modems from different regions on the same model.
Trying to figure out a way for a universal flashing technique in these phones as most of them are the same with only the region lock and recovery check.
Since most of these phones contain the same modem, that's what needs to be done.
Trying to see if I can switch identifier in modems.. If I can fool the checks into thinking one modem is the same region for another
I have an Honor View 10 (global) that isn't working on the LTE bands in the US either. Is it possible to use the North American firmware and flash the global phone? Would that gain access to the LTE bands? Thanks.

I have a US Verson of V10 and not working LTE with some carries in Brazil... Works only on band 3, but here, the carries use 3, 7 and 28. Can you want to change your phone with me ? Rs [email protected]
So, did we figure out how to change bands on View 10 ?
I'm in Canada and using Rogers network. My device is bought from India BKL-L09
I have set the region to Canada
The LTE is working and showing
My problem is that the download speed is horrible (will never exceed 8 mbps).
I've switched my SIM in other devices and I'm getting up to 100mbps.
Any advice?
Has anyone tried to update the OP6 modem with the OP6T modem?
The reason I ask, on the OP6, Band 13 is missing. But apparently on the OP6T, Band 13 is present.
Is it possible that the modem firmware is swappable?

I don't think that's gonna work unless the band frequency is physically capable of reaching that band in the OP6. Even so, there is no guarantee that Verizon or Spring or whatever CDMA operator would accept your device IMEI on their network.
We can already get OP6 to work on Verizon by tossing in an activated SIM, just can't use Band 13 until we find a way to activate it.
Sprint is a whole different story.
Using qxdm and qpst you should be able to unlock bands.
If the hardware is present is another thing
It's the exact same chipset as the 6T. OnePlus may have blown the fuse on Band 13, if so there is no way to activate it after the fuse is blown.
I did try the modem files from a 6T, I got signal on SIM 1 but lost IMEI on SIM 2, so I had to restore my backups. I'll keep investigating it.
I'm curious, since the iphone 12 series is in stores today, it seems that the iphone is using the X55 Qualcomm modem. If I understand correctly, that's the same modem that the Snapdragon Note 20 ultra uses? If so, how come the iphone 12 has so many 5g bands, and the Note 20 ultra is so limited by region? If it's the same modem, why the difference?
If the modems are different, then please ignore my question
What I have noticed is that using the *#272*imei# method and changing it to DSH... I get the exact same amount with the sm-986u1...

Cool, although I'm referring specifically to the 9860 model. Assuming all snapdragon units have the same X55 modem, I don't understand why they don't have the same 5g bands, when Apple has clearly shown that the modem is capable of ALL major 5g bands. Does Samsung specifically gimp the modem?

All the units do have the x55 modem and I am not sure why all the bands aren't available for roaming either. The available bands are controlled by the service mode built into the firmware, then further defined by the CSC. I know here in the US, the CSC controls more than just the 5G band availability as well. I have noticed when using t-mobile while on Verizon CSC, SA 5G won't register any service bars in the corner icon. Also band 41 5g, although enabled, won't connect. And then when using Verizon on Tmobile CSC, 5G n5 won't connect even with DSS and n5 NSA enabled.
It looks like architecture in iPhone is one worldwide firmware that just enables all bands and then available services are further changed by the carrier services from the installed Sim.
I followed this user's notes and I think this did the trick.

i bought oneplus 8t from India and using it in Thailand. Thailand has 5g coverage all over but bands are different. how can i add support of bands in Oneplus8t. please guide
IDK wht they use in Thailand. Maybe you can software unlock it, but you can't add bands that the hardware doesn't support. Try installing the global or eu rom on your phone.

In Thailand AIS Operator uses N41 Band for 5G . the specs of Indian version of oneplus 8t doesnt support that. I tried after installing global Rom as well. it still doesnt support 5G . Is there anyway to manipulate hardware to support that.
Anyone has any suggestions?
usually you can't unlock extra bands if the chipset doesn't support. If the chipset did support it, then it would have worked when you installed the EU rom.
As far as I know you can't unlock/change the bands your device support in any way. Not even by flashing another rom, it is defined on hardware level somewhere. All you can do is to buy a different model of the oneplus 8T that support the bands you want.
Maybe you can try to research the qualcom hack on the oneplus one. It probably won't work, but it might be an idea to start with to unlock extra bands that are hardware locked.
It's not a frequency locked... This B41 is NOT included in your model, so you can do nothing, just by a new 8T global if you want absolutely using 5G. Be careful when you purchase a phone on an another country, you can encounter warrantly problem, frequency compatibility problem and you don't have support.
Technically the Qualcomm modem in the 8T supports all of these bands. However, it's flashed at a hardware level you won't have access to. Sorry, but this is the manufacturer's way of keeping bands they are not authorized to use (device regulations cost money in each country) disabled in the hands of an end-user.
iphone usually supports all the bands everywhere ..even samsung has support to most of the bands... how come a company like oneplus doing so?
