GSM from Tri-band to Quad-band,

Hi, can I change touch dual the GSM from Tri-band to Quad-band,
for the better reception in USA.
I know the touch can do that, Thank

Now that its going to be available in the US with quad band, does it mean tri band niki can be changed to quad band?

I would like to know this too

It could be possible, but the RF chipset could be totally different on the two models.
There wouldn't be much of a reason for HTC to restrict the current tri band duals with the way the various operators have deals with other overseas operators.

You would think they would have designed, developed the radio chip long ago, and the new edition would only contain software changes to the OS, and Hardware soft updates

--bump--
I too would like to know if this is possible. The best buy website has a touch dual listed with 850. I called their customer support and they couldn't give me any information on release date or even a model number. Will the US version of the dual have 850? I want to know if I can get this $500 phone to work here (area code 318 with ATT) on just the 1900 band or do I need the 850 band for better reception. Any advice would be helpful. Thanks in advance.
b

Any luck? I would like to upgrade to the quad band

theres only one version of the dual that is quad band and that is the US version being sold by BEST BUY.

Thanks for the reply I figured I was out of luck, so I ordered the us version yesterday.
Bought the triband Dual but, soon figured out that it doesnt work well in the states.
I thought I would give it a go.
Thanks

Was working on 850MHZ than....
My HTC touch was working on 850 MHZ than I had a tech at my provider's, setting up my internet.
Since that moment it does not work anymore:
Getting the signal but not able to make calls or receive calls.
The guy tried to fix it. It worked for a couple of calls and than stopped working.
Back to the tech, he told me it s because of the 850mhz on which they operate.
He said that even if it was working fine, it wasn't meant for their network (850 MHZ).
Should I believe him?
(the phone works fine with 1900MHZ band from another company)
How can I fix this?

wish there was a radio upgrade like the latest for the diamond that enabled the 850 band

modem hack for Chinese OPO to enable 3G

I thought I might post this in its own thread as it might save people time when they get their Chinese OPOs and notice WCDMA doesn't work..
For all those who don't know, the Chinese OPO does not support WCDMA/FDDLTE in its stock software configuration. You need to swap out the modem to a hacked modem in order to get the feature to work.
I believe the modem attached was pulled from a Find 7, I've tested it, it works. It has been running pretty well for the last week or so but I'll have to test it over the coming weeks to see how reliable it is. They claim 2G/3G but no 4G. 3G/2G works.

For further info (google translate required) :

can you please explain step by step procedure for same?

so your saying that the chinese and world versions of the opo are the same hardware wise and its just a software modem difference?

I have chinese OPO using on T-Mobile in Hungary. 2G/3G/4G are working out of the box, just for you information.

So for three in the UK the Chinese opo might not work at it's best?
Edit: did some research for myself and it will work fine.

As I saw in one of threads on OPO forums it was explained that chinese version do not support only WCDMA band 4.
According to the wiki (UMTS_frequency_bands) this band is used only by following operators:
North America: USA(T-Mobile US, Cincinnati Bell, i wireless), Canada (Eastlink, Mobilicity, Vidéotron, Wind Mobile)
Latin America: Chile(VTR, Nextel), Colombia(TIGO, Movistar), Uruguay(Ancel), Perú(Movistar, Nextel)

The question is can the modem be flashed to support missing WCDMA band 4?

I just flashed the modem on my Chinese OPO and it works flawlessly with China Unicom's 4G service.

Has anyone tried to flash the CM11S factory image and see if that radio activated the bands? The CM11S factory image includes radio images, and I believe is flashed together as a whole.

Yes. Would like to know if the 1700 and 2100 frequency are activated after flashing the modem.

All-
This is the hacked modem for China OPO that supports China Unicom networks.
I have made cwm zip for easiler install as CM would override the modem during OTA upgrades.
This modem comes from the chinese oneplus forum. See link: http://www.oneplusbbs.com/thread-429139-1-1.html

I have tried other networks with the modem from the ColorOS or CM rom, seems there is no restriction on WCDMA for other networks.

A few things,..
1. I've been lead to believe from various sources that the Intl. and Chinese versions of the OPO are in fact almost identical hardware wise.
see: http://www.gizchina.com/2014/06/12/differences-international-chinese-oneplus-one/
2. I don't have a 4G subscription in China so I cannot confirm whether or not it works with this modem hack.
3. I bought my Chinese OPO from a reseller here in China on Taobao. When I received it I immediately flashed it over to CM11s and subsequently had no 3g (I use WCDMA network China Unicom FYI) for a few days until I found the hacked modem on the Chinese OPO forums. As for those of you who are not in China, I've heard that many Int. resellers will complete this process for you so you won't need to do any flashing yourself, but I can't generalise for all of the sellers out there.
4. I cannot confirm is whether or not this is only some kind of restriction for Chinese wcdma networks (China unicom). I haven't as yet taken my OPO out of this country and tried an international sim card so that is yet to be determined.
ThExSenatoR> I'm curious about your phone configuration perhaps you could post which modem version you use printed from the about screen??
sasalove> are you saying that the Chinese OPO will work outside of China on other wcdma networks but will not work inside China on China Unicom with the stock modems from coloros and CM?
can anybody who uses China unicom on 4g confirm which modem you use and if you also had to flash a different modem in order to access the service?

With some testing, I'm quite confident to conclude the restriction for 3G is on China Unicom only. I got my CMHK and one2free sim to confirm it. I can use 3G and 4G without issue in HK.
I occasionally travel to mainland and I got both China Mobile and China Unicom 3G sim. Only the hacked modem got China Unicom 3G and meanwhile the CM modem cannot connect to the TD-SCDMA for China Mobile.
I'm still waiting for my 4G China Mobile to test TD-LTE...
So in any case, I decide to flash this hacked modem, as it seem to work for all to date...

The modem that come with CM11 should have WCDMA band 4 (1700 MHz) and should also have LTE band 4 (1700 MHz) and band 17 (700b MHz). According to the spec, the difference is supporting TD-SCDMA band 34 (2010-2025 MHz) / TD-LTE for band 39 (1900 MHz) for China. Other than that the spec matches both side.
Therefore, if anyone need band 4 and band 17, they should use the modem that come with CM11 which lack in the Chinese modems.

Thanks mate for clearing that up for me! So it seems that this restriction is only for China Unicom, why might that be I wonder? to my knowledge, It's not like the Chinese OPO's are being sold by China mobile directly...
I'd still like to test out 4G for China Unicom but I would like to find a cheap deal to do it. I can never seem to fully understand the mobile plans in China anybody got any suggestions as to how I might find a plan with a decent amount of data (at least 300mb) for less than 100yuan a month ??

Are we certain that the Chinese OPO has the EXACT SAME hardware as the international OPO sold by One plus?
I remember reading people claiming either side.
Just want to make sure that they indeed have the exact same hardware ie. Radio/modem and just need to have different ROM/modem firmware flashed to enable different bands ie. Band 4 (1700) in my case.

There is a newer hacked modem available. The author states the modem is based on CM12S while supporting all 3G/4G in China. Another user claims to test all of the network modes.

Cheers mate! On another note, can anyone confirm what their wifi/cellular peformance is like with either the original or hacked modems? Since I've pretty much only used the hacked modem (the one I posted at the start of the thread), I can add that performance wise, it's significantly worse than my computer and old iPhone 5 when using the wifi from my bedroom. Where I sit in my bedroom I get consistent full reception on my computer and used to get the same on my iPhone 5, on my OPO I get 1 or 2 bars at most irrespective of whether or not I use 2.4ghz or 5ghz...
Anyone else experience similar?

OnePlus Two LTE Bands unlocking

Hello!
I've bought a Chinese version of OP2 and it seems to be doesn't have Band 20 LTE support (800 MHz). :crying:
And I was wondering if it's possible to unlock the band like for OPO?

That's not known yet, but I've got my doubts.

I was scared as you after see that I bought the chinese version which doesn't have the 800mhz; but I checked on this site if my phone will work on the LTE of my carrier:
http://www.willmyphonework.net/
Fortunately it works. The real problem is that the chinese version, having only one IMEI, doesn't allow the use of dual sim outside of the China.
Hope your LTE works!

That's not true regarding the dual Sim, it works in standby mode and can be used when primary Sim is not in use (I know this as I have the Chinese version of the handset and I am using 2 Sim cards).

Yeah can confirm this is the same in Australia.

Yes I have LTE, I've checked before buying, but It still one of the Bands I would like to have (it works well inside the buildings).
And yes, bouth SIMs work in dual standby mode.

me too! I've also bought a chinese version of OP2 and I wanted to unlock band 20.

Also subscribing to the thread! I'm going another way: I have the American version and want to use it in Europe (Poland in particular, so I need band 3).
Has anyone tried the unlocking guides on OP2? Is it only a software issue or do the modems actually differ?

I like use the band 800 in México LTE.
One person respond my question and the process to ONO no function.
Do you have information about other team/member working in this topic?

I followed the same procedure as oneplus two, but stuck on drivers installation.
Would be glad to have a solution on this.

I really need this I have messed up... I had to use a post forwarding service so I found a US one and I live in norway and got the US model.. I have asked if I can trade it for a EU one but they can't because of their policies.. Anyone know what band I need for it to work on LTE in Norway?

I think you can find something interesting reading information below:
With the OnePlus 2, we’ve taken some extra steps to ensure that our device works flawlessly in all the markets we support. A crucial component (no pun intended) is bands support. As you may be aware, LTE bands across the world differ significantly for various reasons (let’s talk about why that is some other time) and certain hardware restrictions make it so that you can only support so many bands in one device.
Thus, there is a trade-off between having all the bands and manufacturing complexity - the more bands you want to support, the more region-specific SKUs you have to create. We opted to make two different versions for two different regions - one EU/India, and one that we call North America. These are both OnePlus Global phones; they ship with Oxygen OS and the proper band support for your region. Besides those, there’s also the Chinese version that ships with Hydrogen OS and Chinese LTE support - this one is not available on oneplus.net (and is almost certainly the version you will get if you buy from anywhere else).
Here’s a breakdown of the differences (for EU/NA, bands in bold only available on that version):
Note that compatibility here refers to LTE, the fastest network currently available. The slower 2G/3G GSM frequencies (below referred to as GSM and WCDMA) are less fragmented and you should be able to get data almost worldwide with the included 2&3G bands regardless of the version. Use http://www.willmyphonework.net/ for easy reference.
EU/Asia
GSM: 850, 900, 1800, 1900MHz
WCDMA: Bands 1/2/5/8
FDD-LTE: Bands 1/3/5/7/8/20
TDD-LTE: Bands 38/40/41
3 and 20 are used almost all over Europe, but not at all in North America. Band 8, although available in both versions, is used in Europe and India but is seeing increasing adoption worldwide.
North America
GSM: 850, 900, 1800, 1900MHz
WCDMA: Bands 1/2/4/5/8
FDD-LTE: Bands 1/2/4/5/7/8/12/17
For NA, the removal of bands 3 & 20 allows us to add all the GSM bands you’ll need.
China
GSM: 850, 900, 1800, 1900MHz
WCDMA: 1/2/5/8
TD-SCDMA: 34/39
TDD-LTE: 38/39/40/41
FDD-LTE: 1/3/7
The Chinese version will have very limited 4G compatibility in Europe and North America. More importantly, it only has one IMEI meaning you will not have dual-SIM capability outside of China. If you like having dual SIMs, do not buy the Chinese version.

Here is procedures to unlock LTE bands in Xiaomi Mi Note Pro. Both mobiles (Xioami and OP2) built same processor so maybe this method is for us. I did not tried it yet.
http://forum.xda-developers.com/mi-...how-to-unlock-lte-frequency-bands-mi-t3215880

it's possible change the Moto G4 plus XT1642 LTE frequency ?

i need the band 4(aws) but the XT1642 just have LTE bands 01/05/07/08/19/20/28
have any way to change or chose the bands? or its hardware
Thanks

I am also wondering about this. Someone please give it a productive thought.

Any ideas on this? I've read about this method http://forum.xda-developers.com/cro...ad-progress-please-leave-im-updating-t2871269 and it should work with the Qualcomm Proccessor of the Moto G4 plus, but I don't know the code to activate the Diag.

There are limitations because of the hardware bits (RF amps) that are missing. For example if the radio works on LTE band 17 (DL 740Mhz, UL 710MHz), then it might be tricked to work in LTE band 12 (DL 737.5MHz, UL 707.5MHz), they are "close enough" to work.
Also I had a Alcatel phone that was sold by T-Mobile with one of the existing bands (LTE 5) de-activated because it was not used by T-Mobile. After unlocking the phone (legally) it would still work poorly on AT&T network - and then I was able to activate that band by using the above software - because the needed RF amps where already present inside.
LTE band 4 AWS is a special animal, the DL and UL frequencies are VERY far apart. Not matching anything else, so even if we can program the radio to work in those bands, the output RF amps will just not be able to perform.

I'd love to say that I understood you but I'm very ignorant about bands and frequencies.
I read that the QC SnapDragon 617 has a X8 LTE Modem (can't link because I'm new, but it's on the QC webpage) which has the Snapdragon Global All Mode, and it's supposed to support band 4 AWS. I don't know if that helps with the output RF amps, or I'm totally doomed.

Yes the X8 Modem supports the bands. But it needs something else to work. Those bits are soldered on the US version and not on the EU one. Similar, on the EU one there is band 20 that is not present on the US hardware.

Does SM-G950 / SM-G950U1 (US Unlocked) support TDD LTE Band 40 (2300MHz)?

I bought an SM-G950U1 (US Unlocked) from Best Buy. Does any one know if it supports TDD LTE Band 40 (2300 MHz)?
There is conflicting information on this! Answers given in various specs vary as follows:
YES (it supports LTE Band 40) --- according to specs given by sellers like Best Buy, B&H, and many online sites like gsmarena, phonearena, frequencycheck.com, etc.
NO (does not support LTE Band 40) --- according to the Samsung support person I talked to over the phone. Also, the FCC filings for SM-G950U do not list TDD LTE Band 40 (they have only one TDD band listed, Band 41, presumably for Sprint). On the other hand, although TDD LTE Band 41 is actually known to work with the SM-G950U1, the official Samsung SM-G950U webpage does not list any TDD band at all, not even Band 41 (it lists only FDD LTE bands).
https://www.samsung.com/us/mobile/phones/galaxy-s/galaxy-s8-64gb--unlocked--sm-g950uzkaxaa
Does anyone know the real answer here? Has anyone actually tested the SM-G950U1 for Band 40 support in a suitable country (Peru, South Africa, India, Australia)?

I bought an SM-G950U1 (US Unlocked) from Best Buy. Does any one know if it supports TDD LTE Band 40 (2300 MHz)?
There is conflicting information on this! Answers given in various specs vary as follows:
YES (it supports LTE Band 40) --- according to specs given by sellers like Best Buy, B&H, and many online sites like gsmarena, phonearena, frequencycheck.com, etc.
NO (does not support LTE Band 40) --- according to the Samsung support person I talked to over the phone. Also, the FCC filings for SM-G950U do not list TDD LTE Band 40 (they have only one TDD band listed, Band 41, presumably for Sprint). On the other hand, although TDD LTE Band 41 is actually known to work with the SM-G950U1, the official Samsung SM-G950U webpage does not list any TDD band at all, not even Band 41 (it lists only FDD LTE bands).

I don't have a carrier that would have Band 40, but here is the thread which lists all bands for different versions of S8. You can try asking there as well.

Thanks. I have posted to the thread you mentioned. It is surprisingly hard to find the answer to such a simple question for such a flagship device!

Band 40 LTE is there. Open phone and dial *#2263# and it will list all bands active in the phone, including 40. It is in mine.

Thanks Danny Noman! The *#2263# code did work and showed Band 40. Wonderful!
One question: The *#*#4636#*#* info menu does not seem to work on the S8 (works on many other android phones). Any idea what might be an equivalent for the S8?
