will European z3c work fully on AT&T or should I wait for US version?

I see that the Sony mobile US site has the z3c listed as coming soon. Is it best to just wait for that to come out or will the European version fully support all of the AT&T bands? I'd hate to import a phone and not get the best reception/internet.
I know it was suggested in another thread that it would work with AT&T but then there was some confusion in another thread about the phone possibly missing 1 or 2 bands. Any help from an expert would be greatly appreciated.

I know Sony's white papers have been wrong in the past (Z1 Compact with glass back, grrrr ) but the one for the Z3 Compact D5803 has 4G bands Bands 1, 2, 3, 4, 5, 7, 8, 13, 17, 20.
I've had a hunt around for AT&T's 4G bands but this seems a but trickier as it seems dependent on region, going by wikipedia it looks like the main bands are 2, 4 and 17 which are all supported by the European version per the above. It probably doesn't help that I'm not from the US and I don't have enough posts to add the URLs, sorry.

I feel like I remember reading back in the day that some companies used bands of the same frequency that weren't cross compatible. It's always made me nervous about buying non US phones. However my info could be wrong.

When I was in the states, I got a AT&T sim card. My phone definitely says that it has the lte bands. Still, it only displayed h+ while I was there. I did not bother to go back to the store and check because the speed was very good anyway. So maybe it's because the bands are different or it was working on 4g but just not displaying it, I don't know.

AT&T must provision your sim for LTE otherwise you'll only receive 3G even if the phone is capable of 4G. Usually they do this based on the IMEI of your device and if it's a non AT&T phone then it won't appear in their database as LTE capable. There are ways for them to manually configure the sim for LTE by contacting support.
The UK model D5803 definitely supports AT&Ts LTE on bands 2, 4, and 17.

Does AT&T have more bands than 2,4,17?

I found when googling AT&T LTE bands that they apparently have also started to use band 5 (850mhz) but that's still supported by the Z3 compact. This was both on AT&T's forums and howardforums but I'm not sure if AT&T need to do something else to enable LTE support on that particular device. I think my own network (3 UK) has to do this as it took a few months for my unlocked Moto X to pick up their 4G network.

From AT&T: https://www.att.com/shop/wireless/byop.html
Refer to the manufacturer's website to verify your unlocked device works with a SIM card on an AT&T GSM network frequency:
• 3G UMTS network 850/1900MHz bands
• 4G LTE network AWS / 700 / 850 / 1900MHz bands
Click to expand...

AWS (1700/2100MHz) is band 4 (Blocks A, B, C, D, E)
700MHz is band 17 (blocks B, C)
850MHz is band 5
1900MHz is band 2
The overwhelming majority of AT&T LTE is on band 17. Bands 2 and 4 are used for additional capacity in some markets and/or some rural/smaller market coverage. I'm not sure they've rolled anything out on band 5 yet, but even so the Z3c has that covered.

OK,
thank you very much for the additional research. It seemed like that was the case but I don't trust my own opinion since I haven't done any real looking into this type of stuff in like 4 years.

To answer your original question, as far as we know there is no US model of the Z3c, only the EU D5803 and Asia D5833. If Sony sells it unlocked in the US it will probably be the D5803.

In preparation, hopefully I'll have it in a week.
Programming non-AT&T devices with the correct APN and MMS data settings

Subscribing since I'm very interested in this phone and my service provider is AT&T

Works great. I live in both NY and San Francisco, and I get LTE everywhere on AT&T.
I imported the D5803 (EU) model through Expansys.

Yes. Just make sure to get the d5803 model.

[Q] Changing/Adding LTE bands?

Hi All!!
Was just wondering if it is at all possible to replace or add/unlock additional LTE bands on our AHD?
As it stands now: ATRIX HD has the following bands and frequencies: LTE 700 and 1700 / 2100 (Bands 4, 17). Both USA.
The problem is LTE was introduced quite recently here in Pakistan and the frequency/band they are using is 1800MHz (Band 3, I believe?). So I can use 3G internet with my AHD but not the LTE.
Now as our phone is also based on the MSM8960 chipset, I did a quick research to see what other MSM8960 chipset phones have in terms of LTE bands. Quite a few do have the 1800MHz freq I need.
RAZR HD: LTE 800 / 1800 / 2600 (Bands 3, 7, 20)
RAZR HD XT925: LTE 700 (Band 13)
RAZR M XT905: LTE 1800 / 2600 (Bands 3, 7)
Photon Q XT897:LTE 1900 (Band 25)
HTC Windows 8X:LTE 700 / 850 / 1700 / 1900 / 2100 (Bands 2, 4, 5, 17) - AT&T
BB Z10:LTE 800 / 900 / 1800 / 2600 (Bands 3, 7, 8, 20) - STL100-2
And I did visit the official Qualcomm page and they say the MSM8960 has "world/multimode" LTE.
Now my question is are we limited by hardware or software?
And this is where I need help understanding the following link:
1) Look at Page 3 of the following PDF file. This shows a complete hardware breakdown of our AHD phone. It shows the various PA (Power Amps) and other components the phone has as well as how data flows. According to this, is our phone limited by hardware to just the bands we have now or is it possible to unlock new bands and use them?
http://www.techinsights.com/uploadedFiles/Public_Website/Content_-_Primary/Marketing/2013/techinsights-motorola-atrix-hd-mb886.pdf
Also the following photo proves that the RTR8600 transceiver on our AHD is capable of LTE @ 1800MHz (Look at 4th Gen column): http://images.anandtech.com/doci/6541/IAR Summit Nov 2012_Serge_Jim_Page_20.png
If not limited by hardware. Has anyone heard of a software called "Qualcomm Prod Support Tool" I ask this because I came across "QPST?" which claims to unlock the bands on Qualcomm processors. While keeping the existing bands unharmed.
This link shows how to use QPST:
2) http://galaxys4root.com/galaxy-s4-t...aws-bands-on-att-galaxy-s4-sgh-i337sgh-i337m/
Also found a thread about QPST WRT Samsung S5:
3) http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
So.
1. Has anyone here ever used QPST or know of any other method to unlock bands (if at all possible)?
2. Can we just flash modem firmware (baseband) from another MSM8960 phones to enable LTE frequencies on AHD? Asking this as CM11 for MSM8960 works on all devices and hardware of all the MSM8960 phones (similar drivers?)
Any and all help/guidance on the matter will be greatly appreciated as my other alternative is replacing the phone I bought not 6 months ago. Also I know of all the legal concerns on this matter as I am not in EU or US I believe I am at little risk of FCC coming after me My point is, please add useful and knowledgeable replies to this thread concerning the topic at hand instead of telling me FCC or AT&T will catch me..
I'm currently rooted with Phil'z Touch recovery(unlocked BL) and CM11. Phone is not locked to AT&T.
Thanks in advance!

Thank you for the info :good:..
I just checked the links and he is failing and the modem keeps crashing but Photon Q has just the one band 25 activated by default? Maybe Moto and Sprint have a thing going there where they limited the hardware to keep the price down and prevent customer from taking their phone to rival networks?
AHD is also used by Bell in Canada I believe.. and they also use band 7 in addition to AT&T's bands 4 and 17? So their might be some hardware in AHD to use the additional bands? Of course this is all my guess work.. however..
@palmbeach05 said that he has successfully activated all bands.. I hope it was for AHD and that he got a chance to test them out That makes me think we have different hardware to Photon Q and gives me hope it would work for me too if it worked for another user?

Look the following link: http://www.comparecellular.com/cell-phones/motorola-atrix-hd-lte/specifications.asp
It lists Bell's variant of AHD capable of ONLY Band 7 for LTE... while in the US they enabled Bands 4 and 17 for AT&T? If this is accurate then we have hardware limited by firmware/software.. and additional bands could be unlocked?
I just need Band 3.. don't mind blocking the rest if that makes the device more stable as I don't travel a whole lot..

AT&T specs on the Atrix HD MB886 -
AFAIK it should be LTE (700 (band 17)) / (1700/ 2100 (band 4)) .
Band 4 is AWS which uses both 1700 & 2100 for up/down but is just referred to by 1700.
Bell LTE bands (from Wikipedia) are 700b (band 17), 1700 (band 4), 2600 (band 7).
From research it seems Bell Canada had 1700 (AWS band 4) up and running in 2011 and then got 2600 (band 7) up and running in July 2012 - the exact time frame they launched the Atrix HD.
While they (Bell) didn't get any 700b (band 17) until they launched last year - 2014.
So it would seem that the HD was indeed running on 2600 when launched by Bell IMO.
I'm quite sure that if @palmbeach05 said he had all bands working then he did.

Waiting for confirmation from him on whether he got this done for AHD or another MSM8960 phone...

1. I think that the biggest battle is getting the PC, software & HD all on the same page - If you know what I mean. Once you get the software to recognize the HD in the correct way your mostly done. I started to do this but had issues and thought I'd save it for another day.
2. I know that Qualcomm regretted leaving the MSM8960 open to DIY reprogramming as they soon updated how they did things - none of their later model chips have this ability.
3. There are some handy programs on the Play Store for computing the NV values
See----->>>> Qualcomm NV Calculator & LTE Band Calculator
4. If you succeed please keep us posted TIA

Just woke up for the day. Yes i did do that unlocking method for the AHD. To check what bands are available, hit *#*#4636#*#* and go to phone info and the three dot menu in the upper right hand corner. You are able to select preffered bands in this menu, which will allow you to make it a global phone instead of just LTE. I'm in the US, so i can only vouch for ATT bands. I haven't tried switching my apns and service to TMobile to check if they are up and running too, but i think i might do that later on today to test it out.
NOTE - Global sticks all the time, including on reboots, when selected while using CM11. CM12 is having issues on that at the moment

Thanks again.. I have no problem sticking to CM11 if it works.. I tried the latest nightly of CM12 last week and my games kept hanging and crashing so I reverted back to CM11.. I'll get an LTE sim in a day or two and then unlock the bands.. be ready for some questions regarding the unlock process

You can actually unlock the bands now if you want, this method deals with the radio/modem, not the sim card

Update - Global finally sticks on 3/10 builds. It must have gotten fixed with all those commits that got pushed out between 3/4 and 3/10 builds

Sorry for not being able to respond for a while.. the week's been crazy and sadly this one looks to be following the same pattern.
So.. I didn't get a chance to try anything out as yet coz of several reasons..
First I lost my phone and thank God there are still good people left on this Earth coz one of them attended my call and brought it back to me!
Secondly my mobile operator is giving me a headache getting that LTE enabled sim.. so waiting for that.. and one top of that I've been busy..
So I apologise but please know that I've not given up on this and will give this a shot soon..

Link #1 is OPO's steps for what I have shared. Link #2 is something i recently discovered and haven't tried. I have the day off so i can test it out and provide feedback, but its now 3 am, i've was sleeping for about 10 hrs before my last post, and the only thing on my mind right now is food lol
UPDATE #1 - After wiping modemst1 and modemst2, I attempted the unlocking of bands by editing line 1877. This method is as effective as doing it the other way with the steps that I provided.
UPDATE #2 - Editing line 441 to reflect 0xFFFF works as well, no issues to report.
UPDATE #3 - Editing line 946 to reflect 0xFFFF works, no issues. Editing line 2954 creates issues. Looking into lines 6828 and 6829 now.

Any Verizon Turbo users on AT&T?

Hello,
I was wondering that now with root and BL unlock, is it possible to enable more bands to work with AT&T LTE? I enjoy the Turbo and having H+ only isn't exactly a deal breaker, but LTE would be nice to have yet. Any help appreciated!

Unless the Droid Turbo XT1254 has the AT&T LTE bands, there's no way to "enable" them.
Besides the Turbo already works on almost any carrier, you just have to edit the APN settings for your network.

That's unfortunate. If you can, you could buy the US Moto Maxx, I'm sure that one has the LTE bands.

Unless the Droid Turbo XT1254 has the AT&T LTE bands, there's no way to "enable" them.
Besides the Turbo already works on almost any carrier, you just have to edit the APN settings for your network.

The Droid Turbo XT1254/U.S. Moto Maxx XT1250 (same identical device, same FCC ID) does not have all the AT&T bands. AT&T uses LTE bands 2, 4, 5, 17.
Only the "international" Moto Maxx XT1225 & Moto Turbo XT1225 has all the AT&T bands. The XT1225 has a different FCC ID from the XT1254/XT1250 -- has no CDMA bands, but has more HSPA bands, and a different mix of LTE bands (bands 5 and 7, but no band 13). The radios between the XT1250/XT1254 and the XT1225 are not compatible, so you cannot flash one over the other.
You CAN use the Droid Turbo/U.S. Moto Maxx on AT&T, but you will not have LTE bands 5 and 17. Here in the Atlanta area, LTE band 17 is used extensively. You would only have LTE bands 2 & 4. For AT&T, you would be missing LTE bands 5 & 17. Which means you would drop down to HSPA (3G) in those areas where 2 & 4 were not available. In metro Atlanta, if I had the Droid Turbo on AT&T I would be on LTE band 2 half the time (north of Atlanta) and HSPA the rest of the time (in Atlanta, and south), since it doesn't have LTE band 17.

All the Quarks share LTE bands 2, 3, 4, and 7. In the FCC letter it only mentions they share LTE bands 2 & 4, because no U.S. carriers use LTE bands 3 & 7, and the FCC is a U.S. regulatory agency.
Can you "enable" LTE bands 5 & 17 on the XT1254/XT1250?
Conversely, can you enable LTE band 13 on the XT1225?
Theoretically you could, since another Quark model has them... but realistically probably not. Samsung, One Plus, and others manufacturers disable bands not needed on their phones for various regions/carriers -- and by rooting and using modem software (ike QPST/QXDM) people have been able to "enable" additional LTE bands in various Snapdragon phones. The Galaxy S5 in Europe has the bands needed there, and the Galaxy S5 in Latin America has the bands needed there. The bands not needed are disabled via software interface, and by editing that people have been able to create "world" phones with all bands enabled! (Google it.)
The difference in Nexus phones is those bands are NOT disabled.
But that only works if the bands were there to begin with, then disabled by the manufacturer. People have tried to add LTE band 20 (used in Europe) to the Moto XT1225 and were not successful. It would show it was enabled but they could not receive/send any signal on that band. The issue is no Quarks anywhere have LTE band 20, so there's not really an LTE band 20 that can be enabled. Like turning on a light switch that's not connected to anything.
HOWEVER, theoretically, since one variant of Quark has LTE band 13 and the other doesn't, and other variant has LTE band 5 & 17 and the other doesn't, you could create a Quark that had ALL the bands between the two: 2, 3, 4, 5, 7, 13, 17.. But it would depend on if Motorola/Lenovo manufacturer is similar process to Samsung and One Plus. Are all those bands there and they just disable what they don't want? Or do they use completely separate radio firmware for both variants?
I don't have the time or patience to go looking for bands I don't need. I did all the band enabling stuff earlier before Motorola admitted the XT1225 had LTE band 5 already.
This is a screenshot of the "3G" bands in QPST. There's similar interface for the LTE bands. But it was a LOT of hassle, and then I found out the XT1225 already had LTE band 5. It was in the FCC tests, but not in the official specs when first released. Only MONTHS later when the XT1225 was released in India (under the Moto Turbo name) did Motorola finally put LTE band 5 in the specs.

Thanks! That was very informative. I'm ok with HSPA+, which I get 90% of the time and LTE the other 10. The Verizon XT1254 even has a proper "H+" icon, I had read previously it says "3G"

Is HSPA+ more battery efficient than LTE I wonder? It's of no consequence since it takes a fair bit of effort to kill the battery in a Turbo, but still curious

I think it is, since it's basically just 3G right? I do know that LTE sips your battery like nothing else though.

I ordered the XT1250 on a whim and was apparently confused on what would and wouldn't work. So after reading this and reading some failures others had in enabling band 17, is it safe to assume that I should probably send it back since I won't have good LTE coverage on LTE (especially if I am moving to Atlanta for grad school at GT next semester)? I bought it when I saw the initial xt1225 vs xt1250 vs xt1254 guide that said the 1250 worked with ATT LTE. So it only works with ATT LTE in some areas?

You won't get LTE band 17 on the XT1250 U.S. Moto Maxx (XT1254 Droid Turbo under another name).
I have AT&T, live in metro Atlanta area and use LTE band 17 quite a bit.
I'm in downtown Atlanta right now at work, and I'm on LTE band 17. North of Atlanta, in the suburbs where I live AT&T uses LTE band 2, and further north towards Chattanooga or west towards Alabama there's a lot of LTE band 4. Georgia Tech of course is smack in downtown Atlanta, so you would be there a lot more than me.
Here's my LTE Discovery log, so you can see.
However, you would still have connectivity on AT&T... You would get LTE bands 2 & 4 where those are available, but you would drop down to HSPA in areas where there was only LTE band 17. Nationwide, AT&T uses LTE bands 2, 4, 5, 17. But, in Georgia (and other states I've traveled) I have not encountered LTE band 5 yet.
The XT1250 and XT1254 are identical, down to the FCC ID. Same CDMA, HSPA, and LTE bands.
The XT1225 has a different FCC ID because it has different mix of LTE bands and greater number of LTE bands (2, 3, 4, 5, 7, 17), more HSPA bands and no CDMA.

Hard to say...I'm just dealing with HSPA+, I average 5meg down and 1.5-2megs up, so it's adequate for most anything. Of course it pulls LTE some of the time also.

Gotcha. Thanks guys. I was thinking since Motorola said the antennas were the same that I could enable band 17, but since that's not the case, I may send it back and save up for the xt1225 or the Moto X Force.

But is it true that 17 can't be enabled? I'm still looking into this myself as I really don't have the means to get a different phone, at least not one on par with the Verizon Turbo.
Sent from my XT1254 using Tapatalk

That's kind of what I was getting. I'm still a bit curious. I read in another thread @ChazzMatt said it would be theoretically possible since the Motorola FCC letter stated that they had the same hardware and antenna, but he did not recommend others trying it.
And yeah, I'm a college kid about to start grad school, so I don't have the means to purchase a new international flagship either. I know that if I get the phone and request the unlock code from Motorola, then my warranty is totally void. I'm used to that, I've unlocked and rooted every phone I've ever owned. So if ChazzMatt thinks bands 5 and 17 may actually be there, I'm willing to jump down that rabbit hole if I keep the phone.
EDIT: Also, having grown up in rural MS, 5 megs down is like lightning. My residence wasn't eligible for any internet service better than hughesnet until two months ago when UVerse became available.

If you're willing to jump through the QPST, QXDM, LTE bands calculator and similar software hoops , you can try. But, if it doesn't work for you, don't blame me. Adding LTE bands 5 and 17 to the XT1250/XT1254 is more feasible than trying to add something like LTE band 20 (Europe) since at least another Quark (XT1225) does have them. Or adding LTE band 13 to the XT1225...since the XT1250/XT1254 has it. But I don't need LTE band 13, so I'm not concerned.
I did a crash course in all this last year, before Motorola finally admitted the XT1225 had LTE band 5. It was there in the FCC tests, but then was not listed in the official specs -- for some strange reason -- when the phone was sold in various Latin American countries. (I think Motorola originally was going to sell the XT1225 through AT&T, which is why it has ALL the AT&T LTE bands, then changed their plans.) Then, when the Moto Turbo XT1225, with the same FCC ID as the Moto Maxx XT1225 debuted in India, Motorola finally listed all the LTE bands.
(Two devices with the same FCC ID have identical communication properties, bands, etc. This is by law, due the American Disabilities Act. Handicapped people depend on this stuff and companies can be fined large amounts of money by the government, plus be liable for MILLIONS in lawsuits from eager lawyers. That was why when I found the XT1250 U.S. Moto Maxx and XT1254 Droid Turbo had the same FCC ID, all the arguments for Verizon "exclusivity" were over. Legally, technically, everything, they are the same device. Don't care if they have different Motorola model names or numbers.)
But I went through all this stuff to enable the "missing" LTE band 5, when it was already there!
By the way, when the FCC tests phones, they only test for bands used by U.S. carriers, which is why for instance LTE band 7 is not listed in the FCC test results, but is listed in the official XT1225 specs. It's a band used extensively in Latin America countries.

Oh, I certainly wouldn't blame you. You never claimed it would actually work, just that it was possible. I haven't read through all the nitty gritty details of the process yet, since I was on the fence about using it. But I do have three questions before I try it:
1) How long do you think it would take?
2) Would I need to repeat the process any time I flashed a new ROM?
3) Is the risk of failure limited more to the bands just not being there or actually hard bricking the phone?
If the process doesn't take a terribly long time and the phone comes in by Wednesday (which it should), I can try it before I head to Georgia Tech for a visit Thursday.

1. I wouldn't rush it
2. No, if successful, the changes would be permanent and persist between ROMs
3. Not sure, if you refer to answer 1 though, you should be alright

Sweet. I may give it a shot. I'm rocking band 2 lte at my current location and back home, so worst case scenario, I don't get it. I'll let you know if I get it working. I'll have to get the phone and unlock the bootloader and all then familiarize myself with Motorola procedures since I'm used to HTC and Samsung.

PSA: The Droid Turbo and The AT&T Network

Hello folks,
Recently I entertained the idea of picking up the Droid Turbo and using it on the AT&T network. Everything that I read stated that one could expected to achieve HSPA or HSPA+ at best. I decided to test this and went ahead and dropped $100 down on a used Turbo courtesy of Craigslist. To my surprise, I have been able to achieve the most rock solid and incredibly fast LTE connection! See the image below for proof!
If you have questions, that I may be able to answer, please let me know! With all of this being said, for those considering picking this phone up and using it with AT&T, don't wait any longer. It is awesome!

That's not true and many, many people on here are using AT&T and T-mobile. You did NOT do a lot of reading and research, especially here on XDA! You couldn't have. Many, many people in this forum have been using the Droid Turbo on AT&T and T-mobile since it went on sale in 2014. Any cursory investigation shows LTE bands compatible with SOME of AT&T's bands and ALL of Verizon's LTE phones are network unlocked by order of the FCC.
The Droid Turbo XT1254 has LTE bands 2, 3, 4, 7, 13.
AT&T uses LTE bands 2, 4, 5, 17.
So, of course you can use the Droid Turbo XT1254 on SOME of AT&T's LTE bands. Just not all of them!

But it's old news so we don't discuss it much anymore.
The problem you will have is in cities like Atlanta, GA where I live where AT&T uses LTE band 17 a lot. In places like that you will have HSPA/HSPA+. In areas where AT&T uses LTE bands 2 and 4 you will be OK. In northern part of Georgia when I drive to Chattanooga, that's mostly LTE band 4.
AT&T uses LTE band 5 very sparsely, and even then mostly (not always, but mostly) to supplement other LTE bands due to congestion. There are very few standalone AT&T LTE band 5 areas, where other bands are not also in use. So, for AT&T you mostly need a phone with LTE bands 2, 4, 17.
You have a phone -- the Droid Turbo XT1254 -- with two of those bands: LTE bands 2 & 4.
I have the sibling Quark, the Moto XT1225 -- so I have all of AT&T's LTE bands.
Get the LTE Discovery app. It will show you what bands you are using. You'll never see LTE band 17 unless someone figures out a way to unlock LTE bands 5 and 17 on the Droid Turbo XT1254 (theoretically possible since all Quarks have the same hardware and same antennas).
As long as you stay in places AT&T uses LTE bands 2 & 4, you will get LTE. IF you drop down to HSPA, it's probably because you are in an LTE band 17 area or just crappy LTE signal in general.
The XT1225 and XT1254/XT1250 all share LTE bands 2, 3, 4, 7.
The XT1225 additionally has LTE band 5 and 17 (more bands used by AT&T).

XDA is great! No doubt about it. I wasn't implying that it is anything but. Just providing information in an easier to find capacity. Have a good day!

Hi there. Is there any possibility to use Droid Turbo on RingPlus (Sprint MVNO). CDMA would be enough for me.

Has anyone tried enabling bands with QPST?

I have a question for all the lucky ones of you who have a Mi Mix.
With most of the Xiaomi phones which are released, people are unhappy about the lack of band support for regions outside of China. I know many people in Europe are unhappy about not having Band 20, those of us in Japan would really like to have UMTS Band 6/19 (among others), Australians want LTE Band 28, and people in the US would like Band 12/17.
As you may know, with some phones, it's possible to unlock these bands by putting the phone into diag mode and using Qualcomm tools like QPST. Here in Japan, it was possible to enable the UMTS Bands 6 and 19 on the Mi5 and the Mi Max, but not possible on the Redmi Note 3 or the Mi5S, so it's really case by case.
Seeing as that the Mi Mix is a concept phone people are crazy about all over the world, I am very curious whether it's possible to enable LTE bands and WCMDA bands on the Mi Mix. I don't want to spend the big money to buy one without first having confidence that I can get it to work on my carrier's bands.
So I'd like to start this discussion. Has anyone tried anything? Successes, failures, please post them all!

This (QPST) is something I have no experience with,but,interested in the subject:
I'm good with the band support (for now) as what's available in my area,with my carrier,is supported (Bands 2 &4 on T-Mobile US,no Band 12 or 66 yet),definitely would be nice for at least Band 12,if possible,as I believe my area will get it eventually.
One side note & a positive one at that:
My MiMix locks-in on a signal & has better/stronger connections than any phone I've used to date. This was really noticeable while commuting back & forth to work today,unbelieveable signal quality.
IDK if the ceramic body is better vs other materials,but,recent flagships from HTC/Samsung/LG pale in comparison vs this phone.

i have MI MIX in hand.
I think we need MIX Diag Driver to make it recognize from pc. MI5 Diag drivers are not the same

I have a question for all the lucky ones of you who have a Mi Mix.
With most of the Xiaomi phones which are released, people are unhappy about the lack of band support for regions outside of China. I know many people in Europe are unhappy about not having Band 20, those of us in Japan would really like to have UMTS Band 6/19 (among others), Australians want LTE Band 28, and people in the US would like Band 12/17.
As you may know, with some phones, it's possible to unlock these bands by putting the phone into diag mode and using Qualcomm tools like QPST. Here in Japan, it was possible to enable the UMTS Bands 6 and 19 on the Mi5 and the Mi Max, but not possible on the Redmi Note 3 or the Mi5S, so it's really case by case.
Seeing as that the Mi Mix is a concept phone people are crazy about all over the world, I am very curious whether it's possible to enable LTE bands and WCMDA bands on the Mi Mix. I don't want to spend the big money to buy one without first having confidence that I can get it to work on my carrier's bands.
So I'd like to start this discussion. Has anyone tried anything? Successes, failures, please post them all!

I may have that 'xtra' mix in a few weeks, will PM you if it pans out and we can see about a software hack to open up other bands.

I've heard the Mi5 diag drivers were usable on the Mi5S, which is the same SD 821, so that's strange. What happens when you put it in diag mode and plug it in? Can I see a screenshot from device manager, or some evidence of what the device is?

I've got one in hand in the states (where I actually do need to unlock band 12 for T-mobile) and a patch cable I made handy in case this thing goes brick mode from us trying stuff, I'm game to be the guinea pig for science.
Fair warning though, while I'm a web developer that's very comfy with terminal, I'm new to the android ADB world, so pretty detailed instructions / links to guides will be needed ha!

Good luck Ken, I hope you are able to crack this bad boy.

first of all I do not have the MIX/any Xiaomi device...but you could try starting here (though think you may have already or have plodded down the path much more already) good luck!

This (QPST) is something I have no experience with,but,interested in the subject:
I'm good with the band support (for now) as what's available in my area,with my carrier,is supported (Bands 2 &4 on T-Mobile US,no Band 12 or 66 yet),definitely would be nice for at least Band 12,if possible,as I believe my area will get it eventually.

Is that band 4 only on LTE? I've seen many spec sheets and the carrier I'm on only has band 4 for 3g.

this is what I have gathered from various sources (so yes Band 4 is both LTE and 3g)
Tmobile
LTE Frequencies:
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
Lower 700 MHz band 12
3G/4G Frequencies (WCDMA):
1700 MHz & 2100 MHz AWS band 4
1900 MHz PCS band 2
2G Frequencies (GSM/GPRS/EDGE):
1900 MHz PCS band 2
ATT
AT&T 4G HSPA and HSPA+ use 850Mhz(Band 5) and 1900Mhz(Band 2) bands
LTE uses Band 17(700Mhz), Band 5(850Mhz), Band 2(1900Mhz),
Band 4(1700/2100Mhz)
LTE B29 (700)
LTE B30 (2300 WCS)

That still doesn't mean the WCDMA Band 4 is enabled. It's possible to have LTE band 4 and not have WCDMA Band 4.

Yes....was just giving the bands and frequencies I know for two GSM carriers in the US. Monitoring the bands at various locations by something like signal check lite (much easier to use/read than lte discovery IMO) would be only way to tell.. If I recall correctly this device has 3g at 850,900,1800,1900 so there is no band 4 on 3g it seems... Although band 4 (1700/2100) COULD be a 3g band too for some devices. Someone with better knowledge can chime in here. I might be wrong.

Update: I have actually successfully forced band twelve with NV values (I can see it stick and unwind the value to see that band 12 is allowed after a reboot). I followed about 10 diff guides to get my bearing on working with the Qualcomm editors and maintenance programs.
Sad to say: the modem in the Mix simply won't do band 12. I talked with a few folks from the Xiaomi Reddit Discord and they confirmed my suspicions that with Xiaomi (with a few exceptions) it is usually hardware that's keeping you off of a band.
I don't personally think there's any amount of software hackery we can do to get bands unlocked.
Edit: I am quite comfortable in ADB / SU and am happy to try any and all suggestions out on my phone in addition to what I've tried already btw. Please do let me know if there's something you think I may have missed following the various unlock threads.

Sorry to hear that the band could not be tapped into...
yes most likely a hardware thing-like Samsung (some of their models exclusively for Latin america have u.s bands but the 'international' variants of the same models will not do the U.S bands no matter what...
I actually opened one of them (got a damaged T239M) and found indeed that the motherboard is different...(so much speculation and folks asking/trying to flash S. American firmware on like the T705, T239 etc, myself included (not possible anyway even if going through TWRP and flashing modem files etc...bootloader and pit all different..so nothing would change with the other parts of the firmware)
so it is highly likely in this case that the modem will not do bands 12, 17 (ATT) and 29, 30 (ATT). However, it is impressive that for a China phone this will even do bands 2, 4 and 5. Huawei models (again supposedly international) except for some variants of the smaller 5-5.2 inch models (not p9, p8, P8 max, x2, t3, t3 pro, or m3 (some of these are the tablet phone types) and numerous other Chinese phones will not do anything more than 1, 3, 7 and then maybe 8 and 20 or a 28. (all useless for North America). Huawei has an M2 variant that has US bands and also on their smaller phones (certain versions)
so for the Mix, you at least have LTE 2, 4 and 5 (though of lesser importance).

can you make a detailed guide with all steps and stuff to enable desidered band ? If not works is the same ...

would like to see if LTE Band 20 can be unlocked

I would love to, it's the first thought I had when both starting a new guide and when I finished getting the phone to look for band 12.
I'm currently _buried_ in a project for work right now (it's taking my nights and a lot of sleep from me ha), so nothing soon. But it's on my list of first contributions I'd like to make to this awesome community!

Would you be able to try Band 20 ?
Thanks

So far my experience is that if the band isn't listed in those spec sheet it isn't there in the hardware (apparently a very Xiaomi thing to do). I'm finding that they rarely software lock you out of the bands, it's usually that their hardware simply doesn't support the band.
