Band 12 and 20 - ZTE Axon 7 Questions & Answers

Hey Guys,
I'm pretty set on the axon 7 as my next phone, however I use UK and USA networks during travel.
Looking at the thread I know adding bands isn't possible, however it looks like the G and U have the same hardware. Can I simply just flash the phone over to U firmware + modem when in the USA and G firmware + modem when in the UK to ensure I get the best of both worlds?
Stops me having to go for pixel or s7!
Cheers.

T-Mobile Band 12 Testing?

Has anyone actually tested a Moto X Pure 2015 in a T-Mobile LTE Band 12 area to see if the phone actually has T-Mobile Band 12 disabled, and how the phone handles that if so?
The Motorola website still shows LTE Band 12, with the footnote that it varies by carrier. Compare this with the Moto G, which initially showed Band 12 and then suddenly Band 12 disappeared from the Motorola specs page without any explanation from Motorola.
TIA...
I am currently on T-Mobile (Ting) in a band 12 active area, and I am only getting band 4.
I've been looking into activating all bands according to the details in some of these threads:

I updated the radio on my HTC with QPST, and it looks like it might be easier with moto since the motos have a special BP Tools mode in the fastboot.
My biggest concern is that we may need a custom kernel first if the base kernel has anti-tamper code.
After I first activated on ting, my phone was stuck in HSPA+ and would not connect via LTE.
I went into the engineering/field test mode using *#*#INFO#*#* (*#*#4636#*#*) and changed the "Set preferred network type" from WCDMA preferred to LTE/GSM auto (PRL).
I also turned off "IMS Registration Required" and turned on SMS over IMS.
There is a "Select Radio Band" feature in the menu that offers 3 choices for "Set GSM/UMTS Band". The options are USA Band, Cellular, and PCS.
I have read that if you make a band selection, the only way to get it back to unspecified is to reflash your radio. This seems particularly bad for those in europe, who often disable their radios by selecting "USA Band".
I of course discovered this after already selecting a preferred band.
Maybe someone with experience with updating the radio on a Moto can weigh in here.
I would like to reflash my radio preference back to unspecified, but I'm not sure how to go about it, or if it actually matters.
Motorola says they are going to add LTE Band 12 for T-Mobile in a software update to Moto X Pure 2015.
When, is the question.
Thanks for letting us know your real world test results.

You need to basically repeat the process you did for your HTC. Enter BPTools mode. Make sure you have the drivers installed (Moto, and either their USB modem driver, or your HTC driver will work as well) and then use QXDM to update your band preference for LTE. Also, make sure to use an up to date QXDM, otherwise it won't work. From what I've heard, it's hit or miss with the 810, because they have updated their anti-tampering code from the 805, and while I haven't tried this yet myself (I'm waiting on Moto update, but only so much longer...) this would be how to get it going. Good luck!
Edit: Also, if you meant just getting your stock settings for your radio back, you can just reflash stock. If you're unlocked (bootloader), you can root, install TWRP recovery and then reflash.
ErikHellstrom, your post was about your HTC?
I am looking for real world results with stock Moto X Style (Pure) 2015 edition phones, with the initial release Android 5.1.1 shipping on these phones in September 2015.
Again: On T-Mobile, LTE Band 12, in areas with Band 12.
Thanks again for any info that anyone can provide.

No I am on MXPE1575, with T-Mobile(Ting) in a Band 12 area.
Motorola has announced plans to roll out the activation of Band 12 and VOLTE to MXPE phones, but not a date.
My understanding is that calls will fail if you are connected to Band 12 without VOLTE, because you can connect to a tower too far away to handle a traditional call.
So if you activate band 12 without activating VOLTE you may end up connecting to towers that cannot facilitate a phone call for you. Although some have said that your phone will hop over to band 4 for call notification. I don't know much about this, so I can't verify.
You should be able to edit your radio using specialized Qualcomm software to activate the radio bands and possibly the VOLTE, if you don't want to wait for the official update from motorola.
Matt at Moto forums seems to be indicating that the Moto Band 12/VOLTE activation updates will be coming quite soon.
Is there any quote or article that says it? If it's true, then I will probably end up getting the phone.

patience brother I am a Verizon customer and also waiting to try out tmobile (again) but with band12 to see how it works.
I test from time to time using simple mobile preloaded sim on ebay they sell on ebay for few bucks 1 place where I am almost everyday has 1 bar and no service and that is in Queens,NY inside the building but once outside signal is perfect.

i'm just excited is all i've been with tmobile since i was 15 years old (nearly 20 years ago) and am hoping this new band 12 improves upon their service around here, but at the moment i get LTE with speeds of about 30mb/s so no complaints, but if i go south about 10 miles i lose service
Since moto has gone pure Android, can we use regular fastboot or do they still use moto-fastboot? If regular fastboot we can just flash a radio.img correct?
I just ordered a Nexus 6 (killer deal on ebay for $300 + free shipping) ... curious to see if I'll notice a big difference in signal strength/quality seeing it has Band 12 enabled. If I do, I guess I'll have a choice to make LOL

Never wanted nexus 6 and never will because it's just to big.
The reason why I am waiting with tmo is I need to test service at 1 place where I spend a lot of time I will actually join my friend who is on the 100$/unlimited so my line will be just 40+ tax. Unlimited everything.
Yeah, its definitely wide ... But it may likely turnout to be a "rental" unless I see substantial signal improvements

Converting US version to EU?

In Nexus 5 there is a possibility to activate EU bands on US version. Can we expect it would be possible on 6P too?
I'd like to know this too. If its possible to activate band 28 on the US version for use in Australia by flashing a different radio (Are all the required amps and antenna things there)
I need band 3, 7 & 28 for LTE
Might not be possible , could be a different version of the radio chip that they use for the other version. would be nice if its as easy as just flashing radios but tend to think it will be more hardware
I was hoping this was possible as well! If it was and one wanted to flash a different radio do you need to unlock the bootloader to do this?
Thanks,
M

most of us are still getting our phones..give it a couple weeks
1) Anyone know if the radio-angler-angler-02.15.img contains ALL radios?
2) If I travel from US to Italy/Germany/Japan will flashing that Image get it done or will I need to do something else?
The US version of the Nexus will work in those countries except Japan without any extra work.

Am I right in thinking that if a specific band (i.e. 20, which isn't on the US version) isn't present the phone will simply use another band? Granted, this might not be LTE but still decent speeds.

Just check what radio frequency uses your carrier and check if it is available in the US model.
But if you buy it in the US, the price plus tax, plus shipping, plus tax in Europe, not worth it. Almost about the same price. Unless you have someone to bring it to you and you dont have to pay shipping nor europe tax.

Add LTE bands

Hi, I have the xt1687 us model, and I was curious if there was anyway to add band 20 for use in the uk. Thank you.
Edit: forgot add its the unlocked version bought from motorola direct.
Aye aye
Fit like, will try find out 4 u bro

I wouldn't recommend it - though there appears to be a way (here for the Moto G5, but the process might be similar https://forum.xda-developers.com/g5/how-to/recovering-2g-3g-set-radio-band-to-usa-t3668767 ) you run the risk of setting the incorrect band and require a firmware flash to repair.
Easiest way to look for 4G access is to go to https://willmyphonework.net/ and enter in your device and the destination for using your device. For US devices, it suggests that EE, O2, 3 UK, Vodafone and Virgin Mobile are some of the providers that can provide 4G LTE on alternative bands over here. Please verify this info before considering purchasing a UK SIM for that carrier, if your device is carrier unlocked, or accessing that network if your carrier has a roaming agreement with them.
EDIT - further investigation for O2, at least, suggests that Band 3 support may only be present in London and large cities, and the main O2 signal is 800 MHz (Band 20), so if you're travelling around the UK, might be worth noting. However, O2 and Vodafone appear to be sharing towers, so you may get 4G/LTE signal regardless if you get switched to Vodafone's network. EE seems to have good coverage and uses the other LTE bands supported by the US devices.

Thank you very much for the response, some food for thought, cheers mate!
Yeah, I wouldn't recommend trying this will any newer Moto device... since like 2015. These bands are locked DEEP within the device, and messing with it is potentially hazardous to your device, meaning if you mess up it is possible that you will get no reception on any band or frequency. I don't think I have seen this successfully done since early Moto G LTE & G2 models, and even then there was a lot of bricked devices.
This is not just a firmware, radio software, or tweak that can be done, it involves going deep into the device with Qualcomm provisioning software (which isn't available through any normal channel) and hunt and peck at various undocumented hexadecimal registry options, which often results in no reception or even a bricked device in some cases. This isn't a Nexus 4 that literally had LTE disabled in a simple radio firmware change.
BTW, ignore all those sites that say they can unlock all LTE bands in any Qualcomm device, it will brick your Moto.
Sorry, but your best bet is just get a new device locally. A simple burner phone if your just there on vacation or for a short stay, or invest in a decent device if you plan on being there for any length of time. There are many options for devices in the EU that we don't have in the US and a relatively cheap one could be sufficient for your needs and use your Moto in WiFi mode for other stuff.

using my axon 7 US model around the world

Hey guys I've had my Axon 7 for almost 2 years now, I am planning a trip to Tokyo for just over 2 weeks at the end of August and want to be able to get a sim in Japan and use my phone as normal. Now our Axon 7 u supports 3/4 of SoftBank lte bands and 2/3 of the other bands it needs. So this option doesn't seem too bad.
Now getting closer to my question.
International or us versions of the a7 all have the snapdragon 820 which contains the modem. This same chip is available around the world including Japan. So
Does the snapdragon 820 have different versions with different modems? Or is the software the reason only certain bands are available in different versions of the phone.
If the software decides which bands are available is it possible to edit it to unlock any bands I may want when I am in Tokyo this summer?
I am on unlocked bootloader twrp etc. and have used lineage os and other ROMs right now on a stock based room rooted
Any help and knowledge is appreciated. I googled around a bit and didn't find much on the subject
Simply having a chip that supports a band is not enough, it needs antennas that are properly modulated and shielded for that frequency.
Even if you were to patch the modem to enable a certain band, you would most likely not get reception at all or cause interference on other channels

I'm guessing you aren't too aquaintanced with custom ROMs and that kinda stuff for the axon 7. lemme explain.
There are 3 versions: A2017 (china), A2017G (Int'l, the one used in Japan i think), and A2017U (US). All of them have different modems.
The updates for each device all come with different NHLOS.bin files, which are the modem files. If you flash the U file on a G you won't have any signal. Sometimes you can even wipe out your IMEIs.
But why do you need LTE for a 2 week trip though? You'll get phone signal and data anyways...

I know all about the different versions of the phone, I've been around here for a while. My first question was simply if the 820 has different versions with different banded modems. After reading your reply I'm still not sure. Like I said I know about the different versions of the phone and the fact that they have different modem firmware. My question was hardware related, based on another guys reply it seems not likely it's there antenna that is the deciding factor in what bands can work as far as hardware is concerned which obviously means there is no possibility of unlocking any bands

What I mean is that installing different modem firmware basically makes the modem inoperable. hence, there are key differences between the models
I'm in Tokyo right now and get LTE on Docomo via band 3, which doesn't seem to be advertised anywhere. I was quite surprised! Speeds have been great!
Technically, it can work in Japan. It will get LTE in urban areas and a mix of LTE and HSPA+ elsewhere. From a practical point of view, the garbage radios in the Axon 7 are a serious problem if you're roaming. Hopping around on different bands and carriers causes the radio to constantly die, lose data, or lock onto the wrong cell tower. You'll have to cycle airplane mode frequently and you can't count on incoming calls/texts working.
I haven't had time to try LineageOS in Japan yet. It seems to have fewer radio problems so it might do OK.
Axon in Japan
Hey, I use a American Axon 7 in Japan with no issues, if you use any MVNO sim that uses NTT Docomo Network you should be fine, for example BicSim, IIJMio Travel sim etc.

Shall I switch A2107G to USA bands?

Hi there. I live in Canada and use A2017G. How to switch it to USA bands and is it safe to do? Or should I wait for Oreo (seems like November)?
Thanks
I think you are stuck with whatever bands that are hardcoded into the G. Probably has something to do with the baseband/radio/modem. I did find an article on XDA awhile back that claims you can add bands to your phone, but it seemed mostly suited toward Samsung. In any case, it doesn't really matter, a G model should still receive a minimum of 4G with most US carriers, but maybe not LTE. I'd imagine Canadian carriers are similar. But I do have to wonder, you live in North America, so why buy a G. The U is the variant that is designed for this region. And U has better support, ROMs, etc.
Maybe you can just flash the A2017U modem

You can't add bands that the phone doesn't have. By changing the daughterboard of an A2017U to an A2017's, a guy simply lost all connectivity, plain and simple. Antenna stuff is hardware stuff.
Oreo won't really add bands either
@Choose an username...: I have read other topics on XDA that say you can use QPST/QFIL to add basebands, on almost any device that has a Qualcomm CPU. But I havent tried this myself. It may just be a matter of placebo, or people wanting to believe that it works, when really nothing may be changing. You could also brick your phone during the attempt, which is part of the reason I havent tried yet.
I think that all A7s have nearly the same hardware, including the same (hardware) modem/radio, but with different basebands enabled/disabled depending on which model you have. But I have no proof of this. I will leave this to people that are willing to deeply dissect the hardware.
And then there are the modem files you can flash, which vary according to your model. I am not sure what would happen if you attempt to flash a A2017G/A2017 modem on a A2017U (or any other combo). I think the worst you will face is a loss of Internet/text/phone calls.
When I first bought my A7 I was going to get the Chinese version from AliExpress, because it has more RAM, storage, and ForceTouch. But then I realized that it doesn't have most of the basebands that my carrier (T-Mobile) supports. And you never know where most of the AE sellers get the hardware, they could be stolen, preowned, whatever. I have bought numerous 'new' items there before, but they ranged in quality, ranging from brand new to fair condition. So I thought better of it and bought a new A2017U from NewEgg, complete with ZTE's Passport warranty and 3 years SquareTrade insurance. And I'm glad I did, since a few months ago I had to make use of that warranty to get my A7 unbricked from DFU, before the tool was available.
I think only differences between A7 models are in processor i.e. bands. There are variants in SD 820.

We're in the same boat... My carrier using AWS bands just like T-MO. A2017G was working perfectly fine maybe missing just one band on LTE. And recently new band was introduced - LTE band 13 (700mhz), which supposed to improve indoor reception - big issue for Axon 7 and AWS. They call it 'Extended Rabge LTE.
So A2017U has that band, but A2017G doesnt. My assumption was that both phones are sharing the same hardware and bands available are controlled by software.
I clicked some numbers and got into some engineering menu where I see choices: USA Bands, Cellular 800. So I picked USA and restarted.
EPIC FAIL!
I lost 3g AWS on SIM1! Only 4G present, which is actually working fine. Just imagine phone with perfect 4G connectivity internet is flying, but you cannot place a phone call... (My carrier - Freedom Mobile doesnt have 2G GSM). I tried to switch it back - no luck
Solution - I use SIM2.
Oreo
Just installed it no OTA had to use sd card. That actually fixed SIM1 band problem. It doesnt seem I have band 13 (that is what I wanted), but connectivity seems better and switching between 3g and 4g is very fast...
