Dear All,
I recently got this device in Hong Kong and is hapi with its performance!
But I am still wondering if this device could actually use the LTE available in HK?
I knw the msm8960 claimed to be capable of utilizing all frequency of radio,
so is it possible that there is some soft lock in the baseband?
Could i flash the baseband or replace the modem driver from other device to access other frequency?
any idea is appreciated!
Thanks!
Vasco
I think it has to modifiy the ROm and the hardware
I tried to figure out, if our Photon Q is supporting more LTE bands than 1900 MHz (#2 or/and #25).
-> http://en.wikipedia.org/wiki/E-UTRA#Frequency_bands_and_channel_bandwidths
On some sites there are reports for having another band. (Have to search again, I think it was 850 MHz, #26 or 700 MHz, #12/#17/#29.)
I have also searched for supported frequencies for MSM8960.
I found some BlackBerry devices based on that SoC and 2 different versions of supported LTE bands.
One version (UK) supported 4 in europe used bands und the other version (US) supported 4 in US/Canada used bands.
I think that the Photon Q is like the BlackBerry US version and supports 4 LTE bands in US/Canada.
If you need a few sites, I will search again and show it to you.
The strange thing is, if I set to LTE only (via 4636) I can see all 4 carrier (germany).
We have 3 bands with LTE on it, but I can only get signal to max 2 of them.
Band 3, 7 and 20 (1800, 2600, 800 MHz).
The weird thing is, that on band #20 (800 MHz) only 3 carrier are active, so it has to be band #3 or #7.
Maybe I'm missinterpreting things and thats just a sideeffect of crossing bands of LTE US and UMTS Germany.
On stock ROM there was another "secret phone code" to see what the phone-part is doing. (From qualcomm I believe.)
I think I will test it some other day, to see which band is active.
At last, I was never been able to "login" or "register" into my carriers network within LTE.
Please discuss about that possibility, I really want to find out, which frequencies are supported by our phone on LTE.

Dear Loader009,
Thanks for your information! I'm really impressed that you could actually search the carrier in 'LTE only from Germany!
Could you please share the version of ROM you are using?
And if possible, any screenshot? I really want it can be used in HK with LTE(1800, 2100 & 2600Mhz)
Also do you have more information about the secret phone code? I think it would be interesting
Actually, I noted that xt925 and xt905 are using the same chip MSM8960 with LTE usable in HK.
Is there anyone can locate the radio/baseband of their rom and port it for XT897?
I am willing to try it with my machine.
If this work, I think we could use this photon q all over the world!
Any idea?
Regards,
Vasco

Of course, I was just blind guessing the hardware for xt926 and xt907 are using the same hardware.
If not, there should be one chip controlling the modem channel of the device to be replaced.
But WHICH ONE???
Any expert in this area can solve this question? I am a dummy for radio stuffs
This seems like it's getting pretty interesting.

Dear all,
I'm also very interested in this topic since I imported a Photon Q to Germany and was wondering if it's possible to use the local LTE 800/1800/2600 bands.
I think the first thing we have to find out is whether the hardware is capable of using other bands than the 1900 band listed on the Motorola website. As Loader009 states he could see LTE carriers which are known to use different bands I assume the hardware can do it. Otherwise the carriers wouldn't have been listed, right? Maybe someone from another country with different frequency bands can check and confirm that he can see those carriers as well?
Thus, the limitation to the 1900 band should be software-made and could be modified by a developer. I hope someone can participate at that point as I don't know much about coding...
I'm using CM10.1.
I can't remember the secret phone code, I have to do research again.
This secret phone code only works on Stock ROM. (I stupidly deleted it, when it wasn't working on CM10 anymore.)
The one secret phone code I used to force "LTE only" was *#*#4636#*#*.
Please DON'T change the baseband (don't even tap on it).
This can do problems to you. (I had to use QPST to recover the supported frequencies.)
Also, developers (afaik) can't modify the modem firmware.
We also don't even know, which LTE bands the Photon Q is capable of. (Except 1900 MHz)
I've got my 32GB SDCard back and will test it in the next few days out.
I hope I'll find that secret phone code, I'll also make a few screenshots.
Got the code!
##33284# <- ##DEBUG#
It only works on stock afair!
I'll test tomorrow, it's about 3am now >.<

I have read the "QU_SnapdragonS4_White_Paper_FNL_Rev6.pdf" and found there following entry:
-----------------------------------------------------------
• Industry’s first fully integrated 3G/4G world/multimode LTE Modem: <<<Supports all of the world’s leading 2G, 3G and 4G LTE standards>>>.
It also includes integrated support for multiple satellite position networks (GPS and GLONASS) as well as short range radios via Bluetooth,
WiFi, FM and NFC.
• Designed for speed, compatibility and power savings:
Snapdragon S4 Processor MSM8960 chipset includes the industry’s only complete platform that integrates all of the world’s leading 2G, 3G and 4G mobile broadband modem technologies on a single chip. This new integrated multimode modem is based on an advanced, programmable architecture that is performance, size and power optimized for the fastest combination of modems available for:
- LTE FDD/TDD (Cat3)
- 3G (DC-HSPA+ Cat 24)
- EV-DO Rev. B
- 1x Advanced
- TD-SCDMA
- GSM/GPRS/EDGE NFC.
Multimode/Multiband Means Worldwide Coverage.
• Support for multiple radio frequencies: Mobile broadband technologies are growing increasingly complex in their implementation. LTE is currently being implemented in over 40 diff erent radio frequency bands throughout the world. To complement its wide range of modem standards supported, Qualcomm has designed the Snapdragon S4 Processor MSM8960 CHIPSET platform to <<< address all commonly-used frequencies (from 700–2600 MHz) and bandwidths up to 20 MHz>>>, allowing its customers to address any mobile network opportunity whether the simplest single frequency implementation to the most extensive multi-frequency global mode, whether 4G, 3G or 2G.
-----------------------------------------------------------
Based on the document the chip can handle all LTE Standards, but it depends on his "advanced, programmable architecture"....as written there and how Motorola / Sprint implemented this, maybe they reduced LTE only to one Standard.
I don't have LTE in my area and so I cannot test this.
That's possibly right.
Something else:
If I remember correctly, somewhere in this forum have been said that for CDMA the internal Sprint "ID"(?) is used.
Maybe that's also the reason why I cannot connect to LTE in my area.
The phone is trying to "login" with the Sprint ID and this of course won't work.
The ##DEBUG# menu wasn't helpfull. It shows frequencies for american standards and not for GSM/WCDMA.
Also the LTE menu is also not very helpfull, it doesn't show frequencies at all.
Any News on this topic?
Maybe one of the developers can give a statement?
Yesterday I tested a LTE compatible SIM card.
My Bro has a Samsung Galaxy S4 with 4G/LTE in my area.
So I've put his SIM-Card into my Photon Q and set LTE only.
I had no luck, the Phone couldn't register into the network for this SIM.
I guess either it has the wrong frequencies or LTE is for inbuilt "SIM" (Sprint SIM?) only.
The latter. LTE is configured only for 1900 MHz which Sprint uses.
LTE is configured only for Sprint's frequencies, however, it supports the United States frequencies of PCS blocks A-G. The G Block is Sprint's current LTE channel, and they may deploy it later on Blocks A through F, depending on if they own the spectrum in a given market. The reason you see EU networks when the phone is in LTE Only Mode is most likely because the Phone still sees GSM signals, but will only connect to LTE ones from those GSM signals. Likewise, in the US, if you force LTE Only and then search for networks, AT&T and T-Mobile US will come up as the GSM carriers the Photon Q sees, rather than the LTE signals it sees.
Setting the Photon to LTE Only will not do anything for LTE in the EU. I suspect that if another carrier in the EU uses the 1900 MHz for LTE, the Photon Q will have no issues connecting to LTE in Europe. But until that time, be happy with HSPA.

There is no unlocking that is need to be done
as the Device is already Unlocked at the LTE band 41
However there are two versions of the Nexus 5 the North American and one for the rest of the world
North America:
GSM: 850/900/1800/1900 MHz
CDMA: Band Class: 0/1/10
WCDMA: Bands: 1/2/4/5/6/8/19
LTE: Bands: 1/2/4/5/17/19/25/26/41
Rest of World:
GSM: 850/900/1800/1900 MHz
WCDMA: Bands: 1/2/4/5/6/8
LTE: Bands: 1/3/5/7/8/20
Please make sure you do indeed have the North American version d280 and not the d281
if you do have the North American version try adding/checking your mobile operators APN settings if that does not work i suggest try to get a new Sim card
My phone is the U.S. version of LG-D820, I have replaced the China Mobile 4G SIM card, also opened a 4G package, but still only use 2G networks

In which case, either
1) Google are wrong - The WRT1605L packaged within the 8974 for the Qualcomm Snapdragon 800 is capable of only 7 LTE bands. This is teh first chip that can do this.
2) Google are not being clear with their specs and perhaps omitting that a few carrier released versions are programmed differently.

Just go to Chinese forums of Nexus 5, there are plenty of discussion of it.
Due to
1. China Mobile have 3 bands (39/40/41, 41 is super set of 38) been allocated, and Nexus 5 supports only band 41, for LTE-TDD.
So, first of all, you MUST MAKE SURE China Mobile is USING band 41 to provide LTE-TDD where you have your tests.
2. Nexus 5 does not support TD-SCDMA, and it seems do not support FR-CSFB. (or China Mobile did not support it yet.)
So, N5 can not go to LTE automatically through the route: 2G (GSM) -> 3G (TDSCDMA) -> 4G(LTE-TDD).
You MUST using *#*#4636#*#*, select "LTE Only" to force it connect to LTE, and then using "LTE/GSM auto (PRL)" to enable it using CSFB for incoming/outgoing voice service.
Ensure you have 4G USIM card and enabled 4G service using SMS.
4G in mainland China
I live in China and am in the market for a new phone. My HTC Desire HD is getting rather cranky in its old age.
Investigating 4G here, I've found that the mainland uses its own band, which no other country uses. Everything I've read about it says that even if you buy a phone in Hong Kong, its 4G won't work here. Now, I have seen some phones advertised on HK websites that say they can use both HK and mainland 4G, but I haven't been able to confirm that on any manufacturer sites. Not to mention, they were substantially more expensive.
Luckily there are some Chinese brands that are really improving their wares. The Huawei Ascend Mate 7 is one, and the XiaoMi Mi4 is another. I'm still wary of buying one though, mostly because, while it will have English, everything on it will be set up for Chinese consumers.
I'll keep looking into it because ideally, I'd really like to have a Nexus 6, or Droid Turbo with 4G that works here.

I'm not sure if the Nexus 5's chipset has bands that are compatible with the Chinese 4G standard TD-LTE (LTE TDD), this thread that talks about adding different bands not originally setup on the N5. Another LINK that may help that discusses the N5 on Chinese 4G networks you may need Google Translate.

We this is the nexus 5 forum. The nexus 6 has a different SoC so nothing here can be assumed as valid for you.
Im wondering if anyone has gone from the Desire Z to the Galaxy S Relay 4G in Europe.
I ask for Europe to make sure it is compatible with most networks over here.
I see there is even ROM development over here with 4.4.4 running I imagine codename "Android L" will probably run as well
Thank you for the comments.
A few have had posts in the q&a or maybe general section, there aren't many posts at all here so I'm sure with minimal effort you'll find the ones I'm referring to

I went from Desire Z to Galaxy S Relay, it works well in Norway.
You need to unlock the phone from T-Mobile, see this thread http://forum.xda-developers.com/showthread.php?t=2255892.
Be aware that this phone is not enabled for 4G (LTE) network, only 3.75G (HSPA+). HSPA+ is marketed as 4G in USA, not in Europe.

3G works in Norway too?
I think by frequencies sadly 3G wont work here where Im at A shame.
900 MHz 3g doesn't work!
I upgraded too from Desire Z to Relay, didn't even realize any 900 Mhz problem. I get always an H or E icon (HSDPA or EDGE), so 900 MHz should be working.
According to specs, the phone should work with these networks:
2G Network GSM 850 / 900 / 1800 / 1900
3G Network HSDPA 850 / 1700 / 1900 / 2100
I have it in Telekom in Slovakia and in the meantime I travelled to NY and got no problem at all (I had it set to manual network selection to save roaming charges).
The phone I bought via ebay was locked (even the seller described it as unlocked) but after firmware downgrade I easily unlocked it. I recommend LiquidSmooth ROM, you'll fall in love with that phone!
My other finalist was Moto Photon Q, it supports GSM but lacks SIM card slot. If you want, there's a guy in Prague, the author of the sim card mod instruction post on xda, that can do it for you. But I chose the easier way. Now I have a small problem with display flex cable (probably too much openings/day) so I'm considering buying another Relay before they're gone with no decent qwerty phone around. And I can leave the current one for spare parts. I had to put away my DZ because of the keyboard. Some keys started to write several characters instead of one and there was no easy way to fix it.
FYI ebay deals in your name with customs, so they charge you immediately and the phone is delivered to your door without customs holding it for a week.

T699 in the UK
Hi.
I did not owed the HTC, I used an Xpreia Pro prior to my S4 Relay. However I have the S4 relay for almost 1 year and I had no problems using it in the UK. I have traveled in Europe (France, Germany, Austria, Hungary, Romania) and I was able to use it without any problems. AFAIK it works just fine on 900 Mhz but in 2G. The big question is what freq of 3G is your network provider using. For example, in UK I'm on EE network which is using 2100 Mhz for 3G and 1800 Mhz for 2G so the device works perfectly. Ifyou are on Movistar Spain than your phone will work fine, since the company is offering 2G on: 900/1800 MHz (both supported by S4 relay) and 900/2100 MHz UMTS ( from which 2100 is supported by the device). In very simple translation 2g will work everywhere without any problem, it might happen that is some places you will not get 3G signal.
Hope it helps.

Just wanted to give some info I found using QPST(qualcomm software) to see what cell bands are configured for our HTC One M8. I even looked at the Rezound bands as well. As most of you know, verizon didn't carrier lock our phones, so if we switch to global or even GSM network, we can use other carriers GSM SIM cards. Just need to properly configure the APN's of course. Below are the bands that the phone will search for when Global Network is selected. I pulled this configuration from my actual device. The Rezound only was missing Bit 19 & 49 selection, but everything else was selected:
[Bit_00] Band Class 0, A-System
[Bit_01] Band Class 0, B-System
[Bit_02] Band Class 1, all blocks
[Bit_07] GSM DCS 1800 band
[Bit_08] GSM Extended GSM (E-GSM) band
[Bit_09] GSM Primary GSM (P-GSM) band
[Bit_19] GSM 850 band
[Bit_21] GSM PCS 1900 band
[Bit_22] WCDMA Band I - EUROPE JAPAN & CHINA IMT 2100 band
[Bit_23] WCDMA Band II - US PCS 1900 band
[Bit_26] WCDMA Band V - US 850 band
[Bit_49] WCDMA Band VIII - EUROPE & JAPAN 900 band
I'm guessing the reason some of us are having issues on Tmobile is that the AWS bands are missing? Can we enable them somehow?

It could possibly be activated using QPST, but there are other steps to do it. The only issue is that since QPST is the QualComm radio programing, there is potential to lose signal quality or lose all radio functionality. That said, it could also be possible to recover by flashing the original firmware or RUU to recover. I now T-mobile uses 1900 GSM PCS band and AWS 1700 mHZ. There is another program I use to actually enable more bands. The program basically converts the selection of bands to a hexidecimal number to use in QPST software to program the added bands. Again, not sure if the Qualcom chip can use it. There is a WCDMA band selection for Bit (25) IV- US 1700 than could be programed to enable. I used a thread from the Sony Xperia forum to help me use the two programs.

Nop, if someone can tell me which Rom has the change bands function then can try that as well. But even after opening the bands I'm only able to get H 14.4mbps.
Are you currently in Europe too? I'm dying to get Vodafone lte on this handset. 3g works fine but I haven't tried the qpst route yet.

In UAE but we use the same LTE bands as Europe. You can try the qpst thing on stock Rom or cleanROM

I have an old phone info app that's the 4636 menu thing. Hadn't tried this before but just tried assigning the bands there. Somehow that just hosed me and now I only get the 1900 band it seems, so phone is radio-less for me now

There's a solution for this problem, if you are s-off-ed. I also did the same thing - i selected USA bands and my phone radio died. Just make a nandroid, flash ARHD , go to the same 4636 menu and it will give you another option in band selection - Auto!! Choose auto, then reboot and make sure you have connection with the network. Then restore from nandroid and you're good to go! I will try to find the link to the original thread!

If it helps you - thank the people in the original thread, i didn't find this solution, i'm just sharing the info!

Thanks that was helpful! Somehow I also had recently loaded a Xposed app to show CPU speed on the top bar. I uninstalled that then after two reboots things came back. So odd, but I'm not complaining at this point.
after a google search it seems people have gotten into problems with chaning bands on verizon devices, the above solutions brings the radio back to life. But it certainly doesn't unlock LTE on europe bands.
So i guess its a lost cause, as it must be a hardware limitation
Yeah disappointing that we can't add those

Unfortunately you can't unlock band 20 at the moment, in fact you might not ever be able to unlock the band. So if it's crucial for you to have band 20, buy a different phone.
However, it's a really nice phone, if if you don't necessarily need the specific band, then this phone is a good buy I believe.
ok thank's a lot
@ggkameleon,
I don't have this phone (yet ) But, my Telco uses Band 20 too.
What I intend to do is use my sim for phone calls/TXT's and get a 'Pay As You Go' LTE sim for Net access.
If you see the most good chines provider don't use B20 Mezu Xiaomi Lenovo why ? And other use it but it's not the more good smartphone or huawei use it but the price are expensive. When you see the last Xiaomi Redmi 3 Redmi note 3 and now MI5 very good smartphone and not expensive.
Hi din't know what is it a 'pay as you go' ?
But if your telco use b20 you can't have 4g lte in b20 ! But if use with b20 the band b7 or b3 the phone connect to b3 or b7 if ist possible or connect to wcdma in 3g network !
But i can't know why meizu pro 5 use the same soc exynos than galaxy s6 and the galaxy s6 work in b20 ! It's not possible to unlock b20 in meizu?

He meant he'll use a second, prepaid sim to get LTE from another provider who uses a different band. Although it's been said that using the dual sim function on this phone reduces battery life quite a bit.
Yes, if you don't have the correct 4G bands, but do have the 3G or 2G bands, your phone will be fully functional, just not have the best speed possible.
It's not just a matter of having the same soc, it's a combination of soc, radio and firmware. In some phones a workaround can be found to unlock the radio, others not.

Ah ! Ok but if they are a provider don't use B20 go it ! Don't use two provider ? Ok it's not possible to unlock.
Me in my country (France) They are 4 provider Free use 2600 for 4g, but it's a new provider and they are not many radio in 4g and even less 3g I test it's not possible. Bouygues use for 4g 1800 2600 and a little 800 it's the best for chinese smartphones but where I leave there are not radio Orange use for 4g 800 2600 and in radio there are two band in city but in campaign only 800 Sfr use 800 2600 and use a lot of 800 and it's actually my provider. I speak with users of chinese phone the best are Bouygues or Orange because the one don't use many 800 and the second if don't possible to use 800 the phone go to H+ (wdcma 900) and the speed of 4g 800 it's the almost the same of H+ wcdma 900 !?
If I buy a Xiaomi or Meizu I do change my provider but the smartphone do use the 3G Wdcma 900 ! I believe do use it.
The problem now it's Xiaomi block the boot loader of the new phones ? I see the new Redmi note 3 Pro it's a more good quality but It's more complicated to change language and don't use B20 ! I'm disappointed.... I stay to see what Xiaomi make for international customers.

Ok i understand
Yes it's not a good idea to use 2 different provider one don't use b20 and one use it !
Because if you have a provider don't use b20 go for this provider Because you paid 2 provider ! It's just if you are in contract you can make this option but it's more expensive.
In France all provider use b20 ! Only one don't use but there are not enought radio.
Thank you for your message I understand it's to complicated to unlock band and it's possible to use only in 3g.
Yes, too complicated or simply not possible with the hardware. Whatever the case, 3G can be more than sufficient.. I have never done anything with my phone that required more speed than 3G.
However, the phone does have a lot of other LTE bands, be sure to double check if there's not one that matches, it was the case for me.
1(2100), 3(1800), 7(2600), 38(2600), 39(1900), 40(2300), 41(2500)
https://en.wikipedia.org/wiki/List_of_LTE_networks_in_Europe according to this, there should be enough in france that match to provide normal LTE operation.
Free Mobile is fine for Mi4c you know
I have LTE in outdoor in all Paris (indoor i'm always on wifi)
Thank you for your support and link
Actually my provider are Sfr (because I have a promotion for one year 10€ calls/sms unlimited ans 20go of data) and I do not want to break this wonderful contract
This provider use fifty/fifty FDD B20 800mhz/B7 2600mhz and UMTS B8 900mhz/B1 2100mhz
That good for Xiaomi Meizu FDD-LTD except FDD B20 800mhz
But there are a new problem with Chinese smartphones the Boatloder are lock now
I use Apple phones after Samsung with 3gs 4s and 5s but now the price of their phones are to much and not as high as the difference of Use Android phones ! It's stupid now to buy a smartphone than 800/1000$ it's not possible to my heart and my wife said go out of home if you buy it !!! Paid us a travel and buy another phones. she's right you know.
I like Xiaomi phones and I stay for the mi5......

Wat about other bands ?
i used also my Mi4c with 2 SIM cards (one private with Free operator and the second one with SFR for pro usage). No real problem with 800mhz band used by the two operators.
Ok thank you

The problem will be in a zone where the SFR antenna will deliver 4G only on the unsupported band, you will have only 3G.
That'all. So, it's up tio you to test in the main zone you are, what bands are used by SFR.
