Phone modem bands - Mate 8 Q&A, Help & Troubleshooting

Hello guys,
Who could find how to unlock all LTE bands of the telephone modem: 2G / 3G / 4G LTE Cat 6 Integrated HiSilicon Balong Modem?

I asked for something pretty similar in another post here. I'd like to unlock the B28 band.
No news for now. Hope someone will find a way to manipulate the modem files to get it done

Any chance to enable all LTE frequency supported by MSM8960?

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!

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.

Can this configuration theoretically be changed / other frequencies be added?
Only if you break BP security.

Sorry, what's that?
IIRC The only place with 850mhz LTE available is the Chicago market and currently no phones at all support it. :crying:

Verizon HTC One M8 - Global Bands Active/configured

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.

I activated all other bands yet i still didn't get LTE, so i assume the restriction is somewhere within the chip perhaps.

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.

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!

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

[Q] LTE Bands for Canadian Version (SM-G920W8)

I was wondering if anyone has had any luck with definitively determining which network bands are offered on the SM-G920W8. I have done a lot of searching today, and everything I seem to read online about this is conflicting. Is there a source out there with this information that someone thinks might be correct?
I am mostly just wondering if my phone will be able to access European networks while traveling.
A related question - if I key in *#2263#, select Band Selection>LTE, I get a listing of LTE bands. Are all of these active on my phone?
I can post screenshots if it helps.

4G LTE not working

Im in Morocco and i have note 5 n920p when i choose LTE/CDMA the phone still on searching for service when i choose automatic the 3g working normally bt no 4G my sim card is 4G and i tried it on htc m8 and xperia z2 the 4g is working but on my note 5 no 4G

just because your other devices have lte you have to check your carriers lte bands and make sure your sprnt note 5 supports the same lte bands also make sure ure apn is correct may not be the same apn as used on other devices carrier net 10 is known for this issue they got like 10 diffrent apns and each one randomly works on each phone.
ive had this issue with my verizon note 5 it didnt support lte bands of att so 2g and 3 g was all i got.
also try automatic.

i eddited to show only 920p bands now its up to u to find iff ure carrier saupports these bands
further note say ure crrier supports gsm band and say its 850 and their lte is for examp 900.
no lte still 2g .
just because a 2g frq matches a lte freq dont mean lte.
ure carriers lte bands have to match 920ps lte bands not 3g or 2g
i try to get this point across to many people and they dont understand
carrier and 920p both have to support the same bands in lte not crossing between lte and 3g/2g no mix and matching dont work that way each is a separate radio and each only pick up the bands specified
