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.

Can this configuration theoretically be changed / other frequencies be added?

IIRC The only place with 850mhz LTE available is the Chicago market and currently no phones at all support it. :crying:

Hello,
I'm curious to know is the 3G HSPA 2100/1700 frequency hardware based or software?
For example can one change the frequency to point say at 850MHz?
I'm currently with Rogers, and their 3G network is not on the same band.
Thanks
Nah, its a hardware restriction. Tmobile did this because 2100-1700 are dedicated 3G pipelines. They device does not have 850 or 1900 wcdma only 21-1700
http://www.phonescoop.com/phones/phone.php?p=1763
this is so it can not be used on at&t 3g.
if i remember correctly 1700 is for d/l and 2100 is for u/l
i dont know much about phones....or the various cellphone network types.
But isn't a frequency a frequency? Wouldn't it be the softwares job to interpret the data on the various frequencies?

True, software could interprete the singnal, it just wouldn't be as efficient.
The easiest comparison I could make would be video enconding on a PC. You can have your PC encode a video in h.264 it will just take a while. Meanwhile your HD-DVR is doing the same thing in real time. The difference is the dedicated chip in the HD-DVR that only does h.264 encoding.
I have no idea if there's a way to get the raw signal from one of the other radios, let alone if there's enough power in the G1 to interpret it without the chip. I'd guess not on both cases.

Nice comparison... but I think it is more like a wireless router. A 802.11b router can't use 802.11g... why not they run on the same frequency? Because it isn't just the frequency you have to look at. G takes a different amount of power than B. Same with the different bands. 2100 take a different amount than 850.
If you really want to see a comparison wiki radio frequencies and you will see why cb radios and those little walkie talkies don't work on all frequencies too. There is a lot more to it than just telling the radio to go up or down a couple numbers.
Nope
Qualcomm 7201 Chipset and Baseband is fully Compatible with 850 / 1700 / 2100 / 1900 Bands
You just have to have additional Component on the Board to have additional Support
Please see the motherboard Diagram its Self Sufficient i think.

I thought it was GSM 850 / GSM 900 / GSM 1800 / GSM 1900 WCDMA 1700 / WCDMA 2100
Is GSM 850 the same as WCDMA 850?
But it looks like you answered two questions with that post... someone else was looking for pics of the phones insides. Good job finding those.
Its all hardware based and will not work on at&t 3G. The phone does not have the hardware to pick up 850/1900mhz frequency. Tmobile did this not to screw people over but because they have no need to. The phone was made for T-mobile there is no reason to support at&t bands.
Just like everyone said, it is a hardware thing. As far as I know, since T-Mobile got the short straw and got the 1700MHz band, there really isn't a "universal" phone now that can operate on all GSM and all 3G frequencies worldwide yet. Manufacturers would have to have like 9 total bands supported and with the trend towards smaller and smaller phones, it's something that gets cut early. So the short of it is this: expecting the G1 to work on AT&T's 3G band is a lot like expecting an FM-only radio to pick up AM signals.....or exactly like expecting an American FM radio to pick up all the FM stations in Japan (which uses a wider FM band.)
But keep in mind that the 1700/2100 numbers don't refer to a specific frequency, but a band of frequencies at or around the number. If you've ever used a shortwave radio, you know that they use terms like "the 11-meter band," which is a range of frequencies with a wavelength of around 11m. Luckily, the range of the 2100MHz band that T-Mobile USA uses overlaps the European band enough to make the phone work over there.
Doesn't the tilt do 1700?

Something Interesting...
I found something that might be of interest... If you install "Any Cut" and create a link for "Phone Info" (Long press on you desktop, then > Shortcut > Any Cut > Activity> Phone Info). Once created, you will have a shortcut on your desktop for "Phone Info". Click the "Phone Info" Shortcut and press the menu key. Then click the menu option "Select radio b..." From here you will have the option to change your radio band:
Set GSM/UMTS band:
Automatic
EURO Band
USA Band
Japan Band
AUS Band
AUS2 Band
This would suggest to me that the radio can be controlled via software. What do the experts think? Do you think we could get 3G working on AT&T's Network?

My phone is locked. I can't use my AT&T SIM. Sorry. But when I switch to different bands, I do loose my signal until I switch back.
I have a friend who builds small electronic devices. If I had a damaged tilt would it be possible to remove the 3G antenna and a few resistors and replace the ones in the G1 to make it work on the ATT 3G bands?
Does anyone know enough about the board construction to know what would need to be replaced?
I did use that activity to change the band to get it to work with my provider here in the United Arab Emirates. The thing is I honestly don't know what they are using, publishing reliable info is not a strong point of the operators around here. I grabbed that of a web-site:
The Middle East operators are using the primary 2.1 GHz band for the UMTS/HSDPA operation. Not too precise eh.
I used the Japan labeled band.(?)
sim unlock GI via 611
I was on the horn with CS anyway and figured it would be worth a try to ask for an unlock code request for my G1, they dont have the magic keygens at the Tmob secret base, they have to request it from the OEM, back in the day they gave them out but after many public keygens they got a bit pickier about who get the keys to the liquor cabnet.
when mine comes Ill get an at&T prepay bump sim and mess about a bit just to prove it wont work, and to everybody else ...CALL 611!! ask them for the unlock code tell um you go back and forth to Europe or Iraq or Pagopago, I may not be necessarry but I always have a bit of fun with the story, it used to be a email system send imei to "[email protected]" and get your code in a few days, the good ole dayz

The Menu is shown as the Chipset Qualcomm 7201 actually supports These Bands, But it Require Radio RF/TS Unit to Actually Push Radio Frequcny via Internal antenna. Seeing the Board Picture it only have 1700 and 2100 RF Units. So even is Chipset is compatible it can not Push the Signal or Received Signal other then it is made for. I think in Future then can alter some Hardware and make it more compatible.
So, I'm wondering if I had a broken tilt with the 850 transmit antenna chip in it if I could have that antenna module removed and put in the G1 would that be all that is needed to work on the ATT 3G network?
Anybody, know if that might work since the chipset seems to support the frequency?
I can't afford to pay more than $175 for my phone. I'm a long time ATT customer and can't/won't change carriers. So, I'm trying to get one off of Craigslist or Ebay for about $250.00 or $275.00.
If anyone knows where I can get one for that price please let me know. If I can get one I'll try the antenna replacement idea.
Hey Guys,
I have a Motorola RAZR HD XT925 which was sourced from Rogers Canada. I was wondering how I can check the devices LTE frequencies? Is there any engineering code and/or menu that would assist with this? This device apparently supports LTE 800 / 1800 / 2600 or LTE 700 / 800 / 1700 / 1800 / 2600 according to GSM Arena. I am wanting to use the LTE 1800MHz frequency in Australia, though cannot get it to connect.
I have tried the following:
Searching for networks manually / letting the device select them automatically
Toggling between 3G only and Automatic (4G/3G/2G)
I definitely have the correct APN settings configured (for Telstra in Australia)
Data is enabled, the SIM card connects to 4G in another mobile
Any assistance would be appreciated, in finding out which LTE network frequencies this device supports.

XT925: (international)
Secondary Cellular Networks: LTE700 (B17), LTE1700/2100 (B4), LTE1800 (B3), LTE2600 (B7), LTE800 (B20)
From what I've read, B3 is Australia's LTE band, so it is supported, but it might be turned off in roger's radio.
Have you tried installing the firmware for Telstra? It's available here: http://sbf.droid-developers.org/van...25_A045_WIG149790_Service1FF_fastboot.xml.zip from this thread: http://forum.xda-developers.com/showthread.php?t=1943879 Maybe switching to your provider's firmware will fix the LTE issue.
Hi
Can you please provide an update. Did you manage to flash the Testra fw and latch in to the LTE 1800 band?
Coz i would like to buy a phone and do the same thing as you. I would not buy if you did not suceed.

Hi. This is a good source here in Australia. Hopefully is updated and current. http://whirlpool.net.au/wiki/mobile_phone_frequencies
Note, however, that LTE is really new here and not yet well implemented. I live in Sydney, but I'm outside of the LTE network at home. I'd have to travel closer to the business district to get it. I think its implemented around the airport as well. LTE is still a work in progress and Telstra is ahead of the game with the other telcos, but you're going to want to be able to connect to their "Next G" or 3.5 G to fallback on otherwise youre going to get 2G.
In any case, you want to make sure your APN settings are correct as well. There is loads of misinformation about that. You can have Telstra set them for you (or at least it worked on my Galaxy S2, haven't tried with this phone since I got it from their store). Try this link and see if it the correct one: http://www.configure.telstra.com.au/telstra/index.jsp
On my Galaxy S2, I had read lots of documentation and had things working but found that after going through a Telstra automated thing (I think the above link), that it set my APNs for me and I ended up with better speed and signal.
Just found this from their site as well concerning their 4G and 3G frequencies: http://www.telstra.com.au/mobile-phones/coverage-networks/networks/
The 2100 frequency on their 3G or NextG (3.5G) may have been turned off at this point; I don't remember. They may still be using it for legacy phones and people on bring your own phone plans but I beleive they had wanted to either shut it down or sell it to another carrier. I don't recall that my SGS2 got 850 ... I just noticed there's tabs on the Telstra page that explains their coverage. Click on them and that's more accurate than what I just typed
I suspect your problem is that you may not be in an LTE covered area. Either that or its your APN settings. Let us know how it goes.
EDIT: Sorry, I didn't read your post properly that the SIM works in another device. If it isn't your APN settings, you can take it to a Telstra store and ask them if they know what the problem is. On occasion they do know what their talking about. You can point them at this web page if need be and it might encourage them to look a little deeper:

The device that I had was sourced from Rogers Canada, and didn't support LTE 1800MHz out of the box. They wouldn't have been able to help.

The 2100 frequency on their 3G or NextG (3.5G) may have been turned off at this point; I don't remember. They may still be using it for legacy phones and people on bring your own phone plans but I beleive they had wanted to either shut it down or sell it to another carrier.

Telstra's 3G 2100MHz network was part of 3GIS, an agreement between Telstra and VHA, which ended on August 31st. Telstra still uses the 3G 2100MHz network frequency, it is actually part of their Next G network now, they however do not advertise this, as very few sites are still using this network frequency, and it is far more important to have a device that supports 3G 850MHz. Telstra lost quite a few 3G 2100MHz sites when 3GIS closed, although all of the areas would have had 3G 850MHz anyhow, so it was not really a big deal.
I want to figure this out once and for all.
What services does this phone support on the 850 MHz band?
The big question is whether UMTS/HSPA works. NYC area has amazing 850 band coverage on AT&T.
If I were to put a prepaid AT&T SIM in my phone, set my phone to only operate on the 850 MHz band, and set the proper APNs (necessary for 3G?); would I be able to get data beyond EDGE?
Only one way to find out...
There's no mystery to it if you read through the [GUIDE] Set up Verizon Galaxy S3 as World GSM Phone (confirmed working) thread and the [BOUNTY] ($205 so far) Enable HSPA+ on 1900 MHz / 1700MHz for VZW Galaxy S3 i535 threads completely....
With the radio software verizon has on the phone, the galaxy s3 is quad band GSM (850/900/1800/1900) and single band WCDMA (2100).
We don't know if it has the hardware for WCDMA 850/900/1900 and until now, nobody has successfully flashed a different radio due to the bootloader lock. Keep an eye on the "enable WCDMA 1700/1900" thread for updates.
And just to answer another question that you might have, when my S3 was rooted and set up to work in Germany, I tried both T-Mobile and AT&T sim cards here in town. The problem with the S3 is that even if you try to select a different WCDMA band in the field test menu, the radio firmware will not allow you to change it from 2100. So in an area with T-Mobile PCS (1900) and AT&T PCS/CELLULAR (1900/850) WCDMA, each test I tried only ran on EDGE.

Wow... That really sucks.
So, there's literally no way to get 3G outside of Verizon aside from MetroPCS EVDO?

The first step is to experiment with different radio files, as one user in the 1700/1900 thread wants to do, but we need to get the secure-boot/bootloader unlocked so those files can be written.
Phones like the Rezound had the hardware for Quad-band WCDMA (3g), but took a radio file flash to make it work. The reason there is a bounty is because we -think- the Verizon S3 has the hardware, it will just take some work to get the software on the phone to talk to that hardware.
I know. I've been following the thread.
Was a little unsure of the details regarding frequencies.
As far as I understand, they're at a dead end. They need JTAG/UART to continue without worrying about bricks.

Yeah, and sadly, I lack the skills and the bounty probably isn't enough to attract a dev with JTAG and a phone to fiddle with to solve our issue
Verizon cdma is ran by nortel dual urban base stations the frequencies are 810-910 and 1840-2000mhz. The LTE is 690-760mhz 1x means that your on 850. 3g means your on 1900 or 850 depending on how far away from the site you are, and 4g means your on LTE. The LTE base station is ericsson but speeds will vary depending on whether or not the site is on fiber or T1 transport. Normally they keep the pre pay customers on the nortel dual urban... Oh by the way we are starting to decommission the lucent cdma on metro pcs sites and convert them to t-mobile GSM but luckily metro uses ericsson for LTE too so there's hope.

Use to calculate Qualcomm NV items for adding GSM / WCDMA / LTE bands.
Do you want to add any GSM / WCDMA / LTE bands to your phone? Then use this app to calculate all needed NV items.
This app is only useful for phone with a Qualcomm chipset.
If you don't know how to add GSM / WCDMA / LTE bands to your phone, please refer to this thread. That thread is for S5 model, but the same principle is also applicable for many other phones, e.g. Samsung, LG, Sony, HTC, Nexus...
You also need some NV editor software (e.g. QPST, QXDM, EFS Professional...) on the PC to write these NV items to your phone.
>> NV items description:
- Adding GSM / WCDMA bands:
NV 01877 - RF Band Configuration
NV 00441 - Band Class Preference
NV 00946 - Expand Band Preference 16 to 32 Bits
NV 02954 - Bits 32 to 63 of Band Preference
- Adding LTE bands:
NV 06828 - LTE BC Configuration
NV 06829 - LTE BC Configuration DIV
DOWNLOAD: https://play.google.com/store/apps/details?id=org.vndnguyen.nvcalc
reserved
This app can show the calculation result in 3 formats: Decimal, Hexadecimal and Byte-swapped Hex.
Update v1.0.5:
- Fix UI issue on some devices.
- Add separate notation settings for GSM/WCDMA and LTE calculation. You should not change the default settings unless you know what you are doing.
I'm intersted in Qualcomm NV access, but not for cell band issues. There appear to be GPS issues with some Samsung phones, and there is some indication that those issues are related to a NV "privacy flag". Apparently older ROMs can turn this bit on and off, but newer ROMs don't - whatever value was left there is "stranded" there. There are people flashing back to CM10.x, setting this bit, then flashing back to CM11. I'm presuming that what is really happening is that they're tweaking this on NV location.
If we could simply read the NV location, we could compare its value to GPS functionality, and see if this is really the issue.
If the above is true, and if we could simply write this one NV location, we'd have a heck of a lot simpler GPS fix.
Thanks, vndnguyen, for your app. And it would be very nice if you add CDMA bands to your app. Thanks again.
if i am interested in enabling umts bands in somewhat old msm7227a based motorola, running gb 2.3.7, with no custom recovery, no custom roms or anything, but rooted.
should i even try?
thanks for making this, i wonder if my Snapdragon 600 on LG G Pro E988 can use this to enable China's TD WCDMA and TD LTE, since FDD is kinda different than TDD

Got a question. I found a discrepancy in your calculator.... Your NV calculator values do not match the NV value of the LTE bands my phone already has. So, how can I trust the calculator to give me correct values for additional bands I wish to enable?
It's at the bottom of this post, but I am putting a lot of information about my phone first, so you know the whole situation.
I have 5.2" 1440p, 3GB RAM Moto Maxx (XT1225), which has Snapdragon 805 -- same as the (Motorola) Nexus 6. In fact it was being tested by Google to be the Nexus 6 (or a Nexus 6 variant) as late as mid-August -- but Google decided to go with the larger size variant and only the larger size variant.
Motorola re-purposed this phone as the Verizon Droid Turbo (XT1254) in the USA and as the Moto Maxx (XT1225) now being sold in a handful of Latin America countries. We already have root, TWRP recovery.
When this phone was being tested by the FCC, it had these LTE bands:
But now being sold as the Moto Maxx (SAME FCC ID number), Motorola enabled more GSM bands and changed one of the LTE bands.
They disabled LTE band 5 (a minor AT&T LTE band), and enabled LTE band 3 (which is used more in Latin America countries).
QPST confirms the 2G/3G bands Motorola now claims for this phone:
Which means the LTE bands they now claim (2, 3, 4, 7, 17) are also probably correct.
Again this phone has the SAME FCC ID NUMBER. And as it's being sold in Puerto Rico (U.S. territory), that is very important. That means there's been no hardware change since U.S. FCC certification -- only software change.
Motorola also promises it has the SAME HARDWARE (including antenna) that the Droid Turbo (XT1254) has (even though the Droid Turbo has a different FCC ID number):
This is also important. It means really, Motorola could not sell the Moto Maxx (XT1225) in Puerto Rico (U.S. territory) under that FCC ID number if any radio-specific hardware had been changed at all.
Thus, we know the additional GSM bands, change in the LTE bands by Motorola was software modem change.
With me so far?
___________________________
Now the discrepancy...
In QXDM NV browser, in Line 6828, the XT1225 phone showed a value of 65630 (for LTE bands 2, 3, 4, 7, 17).
Yet, according to your app, with THESE LTE BANDS enabled (2,3,4,7,17)...
it should be THIS value: 65614.
Now I admit that's CLOSE, but it's not the same.
Therefore, how do I trust the calculator to let me enable MORE bands if this default number does not match in your calculator?
I have edited the values of that line to theoretically enable more LTE bands, but if the beginning number from the phone does not match what your calculator number says, then what exactly have I enabled?

Thank you for your patience for a such long post
But the problem was too simple.
Code:
If supporting LTE Bands are [COLOR="Blue"]2, 4, 5, 7, 17[/COLOR]:
NV 6828 = [COLOR="Red"]65,626[/COLOR]
If supporting LTE Bands are [COLOR="Blue"]2, 3, 4, 7, 17[/COLOR]:
NV 6828 = [COLOR="Red"]65,614[/COLOR]
If supporting LTE Bands are [COLOR="Blue"]2, 3, 4, 5, 7, 17[/COLOR]:
NV 6828 = [COLOR="Red"]65,630[/COLOR]
I don't how how many bands does your phone support. But if the value of NV 6828 in the QXDM NV browser is 65,630, that phone should support the following bands: 2, 3, 4, 5, 7, 17.
There is NO discrepancy here.

So, you are saying the phone supports LTE band 5 out of the box, even though Moto only lists 2,3,4,7,17 on the retail specs?
That after FCC testing they only enabled additional LTE Band 3, but did not disable LTE band 5?
If so, that's interesting.
Only to get you correct: this mod is only to extend the range of usable LTE/GSM bands for roaming, not to extend your connectivity while using your default provider in your home country (e.g. to get better coverage in areas where your default provider has a low signal strenght), right?

Or when changing from one carrier to another in the same country. Many carriers lock down bands the phone could receive, because they want the phone to only be used on their network.
Okay so I'm not really understanding the whole idea behind this. I have a Sony Xperia Z(C6603) and my phone already supports the LTE bands(LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20). My problem is that by default my phone and service provider should be able to have LTE working since my service provider also supports LTE band 4 and 7 on their network but upon choosing LTE network modes it has no reception at all, only 3G and HSPA. So I'm assuming I need to do additional unlocking here on my end for my phone but am not really sure why.
I'm able to access through the hidden menu of *#*#4636#*#* and change radio bands and network modes:
But I haven't changed the radio band and tested it yet because I don't know what the outcome will be and if there are any risks or hard bricking of it and don't know how to revert back to default. My service provider's network supports LTE band 4(2100MHz) and band 7(2600MHz). Would I need to go through QXDM to have these 2 frequencies enabled on my phone? Because I noticed how from the radio band list of my phone shows Euro Band which ends up to be 2600MHz but I'm not sure if that's how to enable LTE because it's Euro radio band. Am I okay as it is with my phone's default radio band and just unlock band 4 and 7 somehow through QXDM? Sorry I'm just really clueless and don't want to risk hard bricking my one and only phone.

Your provider supports LTE bands 4 and 7. Of those two, your phone can receive LTE band 7, but you don't see it. Are you sure LTE band 7 is in your area?
My carrier supports five different LTE bands (and my phone can receive them all), but in my area I only see two of those LTE bands. The others are not used in this area by my carrier (AT&T).

Yeah my carrier supports band 4 and 7 in my area, the towers are everywhere.
I checked it using this website: http://www.ertyu.org/steven_nikkel/cancellsites.html
both 2100/2600 are within all the cellular towers in my area.
edit: so if I'm able to choose LTE network mode on my phone, does that mean the LTE network mode consists of all these frequencies of LTE_BC1, LTE_BC3, LTE_BC5, LTE_BC7, LTE_BC8, LTE_BC20? So everytime I change to LTE only or LTE/GSM etc etc, automatically my phone has 2100MHz and 2600MHz included? Which means I don't need QXDM to unlock anything further? It might just be a sim card defect or something maybe. Sorry I'm just trying to understand more
Hi
I am trying to use a US note 3 (n900a) on Europe, but I frequently lose connectivity (although bars are full). The only solution I found is to fix wcdma to 2100 freq, however this also means that I lose reception when there is only GSM coverage.
This app seems to be the ultimate solution for me to calculate a custom NV for GSM+wcdma2100. Am I right?
If so, may I use a NV writer without a box, by just using my usb cable?
Thanks a lot

Hello,
I've got a LG Phoenix 2(K371) phone that I bought from Bestbuy and unlocked through AT&T
The phone is supposed to support the UMTS B1(2100 Mhz) frequency (as stated in specs).
I'm in North Africa right now for a business trip and unfortunately I wasn't able to get any 3G data with the local carrier that uses the UMTS 2100 Mhz frequency, I'm stuck with only 2G while my other phone works just fine.
I tried to change my Network Mode from 4G to 3G but the Network mode menu is missing!!!!!!
My questions are:
1- Does the K371 really supports the UMTS 2100 Mhz frequency ?
2- How can I change my Network mode from 4G/Lte to 3g/WCDMA?
Thanks
Did you ever get this sorted out? I am in Germany and can only get 2G also.
Same here in the UK! Only 2G.
My understanding is that either the official specifications of the phone are wrong - it doesn't support the HSDPA frequency of 2100 MHz, or (most likely) this frequency is disabled in the phone software settings since [email protected] doesn't use this frequency in the US. In any case it is very frustrating: I bought this phone convinced it is going to work while I am travelling in Europe, but obviously it doesn't as 2G data connection is useless.
Same problem in SE Asia. Phone doesn't have the right LTE bands but HSPC should work. Only getting 2G. No option in the hidden menu to change the modem RAT settings that I can see. *#546368#*371#
Anyone have any luck using the k371 overseas?
Same here...
I tried every single method I know in hopes that I could root the phone, but no luck!!!
I believe at&t disabled the said frequencies....
Our only bet is a proper root, and a custom rom..
any update on no UMTS 2100Mhz?
any solutoion on this issue?
I have found a solution. I am using it outside the US. I contacted my cellular provider, gave them the phone name (LG K371) and they sent me a text message with automatic settings for their data network. As soon as I opened it, I got a message like "data settings have been updated" and now it works on 3G and 4G without any issues. You may also be able to find these data configuration settings on your cell service provider's web site.
Seriously???
Please let me know is it AIRTEL service? since i am from INDIA.
we have the same problem in 2 mobiles..
Hmmm
I tried of calling and received setting for MMS , GPRS, INERNET but still i m seeing 2G symbol as E - edge detection
Please help me
Hi this is sainath
am also facing same problem, any one got solutions

Sorry for a late reply, but here's the real scoop about the LG K371 (AT&T)
First, being a "cheap" LG phone, there are very few bands actually included, and they only cover the main (not all) AT&T US frequencies, therefore it's no surprise that doesn't work on all overseas carriers. Again, they are covering only major US bands, and despite what it shows on the box or specs it may not be always true. B1 (2,100Mhz) band has different sub-bands, therefore it doesn't mean that the US B1 will work on an overseas B1, let alone the air-interface (2G/3G/4G/LTE) may not all be supported even if this sub-band exists.
Second, being that it's an AT&T phone, they are knows to load firmware with major restrictions for band selection called RAT Restrictions, which cannot be undone unless you can reflash it with a non-customized firmware, but you can't do that either due to the locked bootloader. A better option is to always go with the un-customized or Tmobile K7/K8 because they always have a lot more bands enabled than the AT&T version. Better yet, go with a Samsung which have more bands even on the AT&T models.
Bottom line, "cheap" phones along with AT&T restrictions will not work everywhere, despite the specs, and there's nothing you can do about it.
And my favorite old adage is "You get what you pay for!" LOL
