hello, just wondering if i can change 4G bands on my Motorola 4G Plus (XT1642) i cannot use 4G on USA or Mexico, only 3G or H+, i was checking on google and saw something to change baseband to unlock all bands or something like that, can some expert tell me if this is possible or not?? here is my Phone Information:

Thanks for your help
Just wondering if I need to change the Modem file or something to make it work on another country as 4G
Same issue in the Netherlands with my Moto Plus. No 4G only G3 or lower
the weird thing is that no one knows if this is possible lol, no experts yet for moto g4 plus
Or it has multiple bands and it's unclear what you want to change. It has Edge HSPA and LTE for GSM and evdo and LTE for CMDA. That makes it a true world phone. Unless your variant does not support it.

Do that and you probably wont have service at all. I don't think anyone has been able to unlocked bands.

No it's still stock android, though if i use my Galaxy s5 4G pops up immediately
Did not see any reason to use custom rom jet...
Got it fixed, call your provider and ask to reset QOS / data. 4G pops right up after restart.
For those wondering: it's not possible. One can technically unlock additional bands following QPST tutorials, and actually changes does stick, however model number cannot be changed which is the one that "tells" the device which bands to use. This has been my personal experience
It's not that. You can unlock the bands with QPST, but if the actual RF amplifiers cannot work on those bands, you won't get signal. One can be lucky if for example adds 800MHz band to a device that already has 850MHz, but the signal strength might be lower than expected.

I did "add" via Qualcomm software the EU band 20 to my US phone that had band 5, and I will be able to test it when I get there next week. The US phone has the other main two EU bands (bands 3 and 7, urban mostly).

So you're telling me there's a chance? I do have a XT1622 which has bands 1(2100), 3(1800), 5(850), 7(2600), 8(900), 19(800), 20(800), 28(700), 40(2300). I'm trying to use it with band 4 (1700/2100), what should I try next then?
Band 4 is "special" because it has such a wide frequency difference between uplink and downlink that I doubt it will work. The UL for band 4 is the same like band 3, but the DL for band 4 is more like band 1.
Not sure if they can be "coupled" like that, it might... Qualcomm modem reprogramming - to get in that mode it's easy on our phones, Power on + Vol Up and then scroll to Qcom... You need the special software (2 pieces, both running in the same time on PC), don't ask me how, just search on XDA.

Dear All,
I have bought a Note 3 in USA with serial number as follows: N9005GSMH and FCC:A3LSMN9005.
I have a problem because I don't know how to make LTE working. I'm using this smartphone in Poland, in settings I can't see option which allows to switch to LTE band. I have good LTE network coverage in my city but I haven't possibility to switch radio to LTE.
This is new phone so it is not rooted, two weeks ago new official update was made from JB to KK.
Can anybody advice how make LTE option visible in network settings?
I have found somewhere on this forum that after making some changes in configuration file in system directory LTE option appear in settings. But maybe it can be done without rooting?
Best Regards
Wojciech

As you bought from America you need to be aware that some of the 4G/LTE bands are different and won't work overseas... If this is the case you might not be able to get the right bands thus all you will get is 3G speeds....

Thank you for your answer. I have found that N9005 is LTE enabled and it supports some of LTE bands in my country.
N9005 supports LTE 2100/1800/850/1600/800Mhz(Band1,3,5,7,20).

This is what you need to know - The LTE standard covers a range of many different bands, each of which is designated by both a frequency and a band number. In North America, 700, 800, 1900, 1700/2100 (AWS) and 2600 MHz (Rogers Communications, Bell Canada) are used (bands 4, 7, 12, 13, 17, 25); 800, 900, 1800, 2600 MHz in Europe(bands 3, 7, 20); 1800 and 2600.
There is a difference...

I have an unbranded Note 3: sm-n9005 (bought in Russia), and I would like to know if there is a way to change the bands being used by the phone so that I can program the correct bands and use the LTE network with Bell Mobility.
I am currently with Bell Mobility and the following info is from my note 3

It seems a lot of people are asking this, It should be as simple as flashing your regions modem but this doesn't seem to be the case...
As I have never needed to do this I unfortunately don't have an answer...
This is an expensive little toy and I don't want to be responsible for screwing up yours.
If I was going to try then I'd try to flash the GSM and LTE modems. Flashing only one might cause a conflict, however this may also render your phone unusable...
If you're not seeing the LTE option in Network Mode, that's because your provider code isn't active in the little file that tells your phone it has LTE enabled on their network. Evidently, as you bought the phone in an entirely different region.
You'd have to flash the local firmware over it, but whether that's a safe thing to do on a US device, someone else will be more qualified to inform you.

So I'm not the brightest with the different frequencies etc... What I do know is that Band 12 on T-Mobile has greater building penetration, and that it's currently not supported on the Nexus 6P, despite the phone having the band. My question is, what functionality do I lose? Aside from having more penetrating power, which gives me better signal, do I lose anything else? Honestly, I'm pretty sure Band 12 isn't even in Columbus, Ohio (where I am) yet... but I don't wanna buy this phone and then Band 12 go live here and then I lose LTE, if that's even what happens... or would it just resort to the current band 4?

Thats trouble for you. From what I understand there is a long certification process to get the certification from T-Mobile, especially if they do not sell the phone. The Nexus 6 DOES support the T-Mobile band 12:
Unlocked devices
The following unlocked phones not only support LTE band 12 but all other bands required to be compatible with T-Mobile network (LTE bands 2, 4 and 12, HSPA+ on AWS and 1900 MHz, and GSM on 1900 MHz) however band support is not the only requirement. T-Mobile issued a statement regarding band 12 unlocked phones: All Band 12 LTE devices on our network must support VoLTE, E911. Currently only three unlocked phones supports VoLTE and band 12:
Nexus 6 XT1103 (US model)
iPhone 6s A1688 and A1633
iPhone 6s Plus A1689 and A1634

well tmobile has already confirm the 5x/6p will work on their network... im just wondering what the lack of band 12 support (for the time being), means for me. i assume i would continue to run on the band 4 that i do now.
Not sure if you've found the answer to your question or not. If you dont have Band 12 where you're located then its really a moot point. I'm in Phoenix and there is a TV station still operating on the 700Mhz Band 12 spectrum so I dont have it. However, if T-Mobile lights up Band 12 and these phones havent received their certification then they will not use Band 12 at all. That means you're limited to Band 2 and Band 4 LTE. Assuming you dont have Band 12 in your area (it appears you do not based on the de-facto map that most cite reference to is here http://www.tmonews.com/700mhz-lte-map/), your coverage will remain the same as it is now.
That being said, Google has stated that they are working with T-Mobile to have the 6p certified by the time the devices ship. So if that holds true, and T-Mobile rolls out Band 12 coverage in your area you should theoretically get better indoor LTE coverage since low-band spectrum travels farther and has an easier time passing through obstacles like block walls. Until then, you should have a similar coverage experience to what you have now. You're not "losing" anything to answer your question.
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.
Is there any way to switch the lte bands. Normally I would dial #*#*4636*#*# but the phone information is saying its not available on this device. Both my nexus 6p and my old note 7 got good signal but this phone is horrible as far as signal strength goes.

this is my question as well. AT&T page for V20 lists LTE bands and band 17 is NOT among them. band 17 is supposedly the main ATT LTE band, which basically means you will only be able to get LTE on V20 on ATT on the backup LTE bands where they are available ...
i'm looking for confirmation that this is true, because who knows - maybe some idiot just forgot to type in number 17 on that info page ...
Notes, iPhones and Pixel all have band 17 ...
obviously i won't be getting iPhone and i can't get the Note. i didn't really want to get the Pixel because i feel like it's overpriced ...
but if what you're saying about V20 getting bad signal is true then Pixel may be the only choice ...
i started having my suspicions about V20 when i heard it won't be coming out in UK, which i thought was very odd ... but apparently one difference between Snapdragon 821 in Pixel and 820 in V20 is that 821 has more LTE bands, which would make it better both for ATT and better as a global phone for travel ...
again, i'm looking for confirmation that this is true.

If you're talking about being able to choose specific LTE bands, I do that on my Tmobile handset using this dial code (use at your own risk)
*#546368#*918# - for AT&T you need to use 910 or 915 depending on your model # (not sure why AT&T has 2 different model #'s)
So it would be
*#546368#*910# or *#546368#*915#
Then

THAT IS NOT THE DIFFERENCE. Modem and CPU part of the SOC are totally different things. The pixel is and unlocked and more likely to support more bands as unlocked phones tend to be more globally friendly. Chances are that certain bands are on there but T-Mobile has it disabled or LG. T-Mobile is usually more bands friendly but not always, as the HTC M8 was seriously gimped in the LTE bands, didn't even support T-Mobile's band 12. I would look at the unlocked version of the V20 to decipher more info.
And you're welcome for the undeserved thanks. Your comment made no sense. Qualcomm modems for certain phones are usually about 2-5 different sets depending on markets a phone will serve. It is usually 2 or 3 when the phone is released worldwide basically and every carrier and market will have certain bands disabled for whatever reason. It also rare for developers to enable them as it takes specialized hardware or knowledge of the software. Another factor is if the antenna for certain bands are even in the phone. No antenna for a band then no firmware will ever be able to enable it, much less some hijinks tweaking.

OK i followed your advice and looked up Unlocked V20. i'm not allowed to post links yet but from bhphotovideo page the unlocked US version has LTE bands: 2, 3, 4, 5, 7, 12, 13, 17, 20, 25 which includes the band 17 ...
while the ATT page lists LTE bands: 1, 2 ,3, 4, 5, 7, 12, 20, 29, and 30 which does NOT include band 17 ...
now the question is, assuming that information is correct, why on earth would ATT chose the version of a phone that doesn't have the main ATT band ?
is there any way to find out whether the above information is accurate ?
as an ATT subscriber, would there be any advantage / disadvantage for getting unlocked phone from B&H versus ATT branded phone from ATT ?
should i try to contact some sort of ATT technical support to try and get an answer ?
EDIT:
according to article titled "LG V20 Model Numbers (F800, H910, H918, H990 DS Dual, H990N Dual, H990T, LS997, US996, VS995) Differences" from techwalls dot com the ATT version has bands: 1,2,3,4,5,7,12,17,20,30 which again has the band 17. it has same number of bands but compared to information on ATT page it subtracts band 29 and adds band 17 ...
frankly, this makes far more sense than ATT page info, but for 800 bucks i need to know for sure ...
EDIT:
according to frequencycheck website the ATT version of V20 ( H910 / H915 ) supports all ( 8 out of 8 ) bands used by ATT, all 4 LTE bands as well as both GSM and both UMTS bands used by ATT.
according to LG's own website H910 has: 2/4/5/12/29/30, Roaming 1/3/7/20, and CA ... which is the same was what ATT lists except for "CA" ...
Band 12 replaces band 17
The way I understand it, band 12 and band 17 covers the same frequency range. At&t has achieved (they were forced by FCC) interoperability between band 12 and 17 now. So band 17 is essentially obsolete and only useful if you are on the at&t network. If you have band 12 capability on your phone, you can use any 700mhz at&t tower that formerly may have only supported band 17. Now all those towers support both bands. And you can use smaller carrier towers too if you have band 12 capability.
Hi Folks,
I thought I had found a gold-mine here in the United States in the H870DS because it has the quad-DAC and the bands look to be compatible with AT&T and T-mobile. The seller listed band 2 LTE and sadly, according to the box, it is not supported and this is one of AT&T's main bands in my area in California. It still has band 12/17, so, I figured I'd be okay. I cannot for the life of me get it to connect to any LTE though. I've checked and re-checked the APN settings, the network settings (4G preferred) and am out of ideas. Does anyone have this phone and have you successfully gotten it to connect to LTE in the United States? I don't have a T-mobile SIM anymore to try.
-Collin-
I believe AT&T SIMs have issues with LTE on non-AT&T devices until the device IMEI is added into their system.
I am not an AT&T user so I forget the specifics but people often have to call in and have the device IMEI added to their account.. or sometimes this happens automatically after a few hours.
What bands are listed on the box? The thread on XDA listing all the bands shows your model as having B2 LTE (Possible the thread is not correct though) https://forum.xda-developers.com/lg-g6/how-to/info-lg-g6-models-bands-t3571221
I have searched some of the AT&T user forums, it is because different areas have different coverage and certain bands are not licensed properly, so you might not get any LTE signals. I do not know if that is true. But my G6 sure does not have LTE whatsoever.
Thanks for the replies guys. Well, I managed to pick up Band 4 when I walked down the street. I still cannot get 17/12 which is weird because it's the primary LTE band for AT&T. The bummer is that now that I know LTE is working, I can 100% confirm that LTE Band 2 is missing. The eBay listings are wrong and the XDA listing is wrong. I've attached a photo of the box. Oh well
-Collin-
I was interested in picking up an 870DS unit myself. I noticed the discrepancy when it comes to band 2. That had me worried, so I did not pick it up. The 870 DS box shows that band 2 is missing. I have to assume that is correct, so I did not buy.
Sorry to hear that i was thinking of picking up the Korean version myself but if I can't get reliable LTE on att no thanks. I wonder if you could return it to the seller since its technically false advertisement
Well this is unfortunate. I just got mine from Ebay today and was wondering why I couldn't get an LTE signal. The seller did list Band 2 so I'm hoping they will refund my purchase or there is a way to edit the radio.
Sorry for the off-topic question but could anyone tell if the H870DS would support 3G simultaneously on both radios (or 4G on one and 3G on the other simultaneously)? If so it would be worth mentioning here as well.

I am using T-Mobile SIM at SIM 1 and my home country carrier's SIM at SIM2.
It is getting LTE at SIM 1 and UMTS (roaming at AT&T network) at SIM 2.
Fi (T-mobile) is working perfectly for me, full LTE. Cricket (At&t) is hspa+ but no LTE.
For the price I am not unhappy even though I usually use cricket as my primary data sim. It's not what I expected but I knew going in I was shooting craps as there just wasn't a ton of information out for this H870DS variant. It's not a huge upgrade over 3t, just needed to switch it up for a while. I am quite enjoying the screen, camera, and HiFi dac without losing my 2 sim setup.
Edit: Sim one does have full LTE while Sim 2 does not.
The references definitely need to show that there is no B2, B17, or B30 for ATT users though, pretty much a let down there.

I actually got Band 4 to connect on AT&T, but it's pretty sparse and not reliable. I switched that line over to T-Mobile and it works perfectly just as you describe.
I like the phone a lot more than I thought I would. It feels so solidly constructed and the camera I really missed from the V20. I prefer this camera to the one on my S8 9 times out of 10. It's a hair slower to focus, but everything else is better for me.
What's odd is that on AT&T Band 12 is supposed to be compatible with Band 17. On T-Mobile, I connect to Band 12 just fine, but not on Cricket. Oh well, my Cricket line has been canceled anyhow

I'm in San Francisco and unable to get LTE on AT&T or T-Mobile on the H870DS. These LTE bands are listed on the box: 1, 3, 4, 5, 7, 8, 12, 20, 26, 28, 38, 39, 40, 41.
Hi there,
I'm in new Mexico on a at&t go phone plan and on a h870ds.
and I'm defenetly getting LTE.
Does the LG G6 actually reveal the used channel and so the frequency band?
On many Android phones this information will show up after dialing *#*#4636#*#* and tapping "Phone Information" - on the very bottom of this screen you will find a list of available cells including their channel number (called EARFCN for LTE/4G, UARFCN for UMTS/3G and ARFCN for GSM/2G). You can then lookup to which frequency band the EARFCN/UARFCN/ARFCN belongs, e.g. at http://niviuk.free.fr/lte_band.php
Take a look at the 'LTE Discovery' app. The free version will probably have what you need.

I can confirm the lack of LTE on T-Mobile in Southern California as well. Very odd as others are reporting success getting LTE on TMO in other geographic locations. :crying:

Doesn't seem odd at all considering that according to frequencycheck.com, some key bands are missing:
T-Mobile LTE Bands
B2 (1900 PCS)
B4 (1700/2100 AWS 1)
B12 (700 ac)
B66
ATT LTE Bands
B2 (1900 PCS)
B4 (1700/2100 AWS 1)
B17 (700 bc)
B30 (2300 WCS)

As noted on the box as well as other first hand accounts, the H870DS does support both B4 and B12 required for T-Mobile. My G3 and my wife's previous 860N both connect(ed) with B4.
On top of this, I now have a solution to the problem via updating the APN settings. The magic change was simply adding ”xcap” to the APN Type setting and setting the Network Mode for SIM1 to GSM/WCDMA/LTE auto radio button.

It's possible that if you're in an area where only T-Mobile B2 or ATT B30 is available then you wouldn't have LTE.
Was finally able to get 4G LTE in AZ on Band 4. Create a new APN with these settings and make sure network is GSM/CDMA/LTE Auto.
Edit: Also, I had AT&T update their system with the IMEI number of this 870DS that I'm using. That might have something to do with it. It took a couple of weeks too.
