#*#*4636*#*# try this. Not sure if what your looking for is here. But this has been in aosp since the beginning
[Google Pixel XL Questions & Answers] xdadevnube:
I believe that is simply the 'Phone Information' screen, where you can pick LTE, GSM, EVDO only etc. I was specifically asking about an Engineering screen. Samsung's Service Mode being the most powerful but I've never seen it ported to AOSP.

HTC, LG, and Motorola have their own Engineering screens, though it seems to differ depending on device and VZW does a great job of locking it out on their devices.

I thought there might be an HTC Engineering screen for the Pixel, considering HTC built the device. However, I've never seen an HTC with AOSP with an Engineering screen either!
[Google Pixel XL Questions & Answers] cstark27:
I am no guru and just regurgitating my understanding of what I've read. Talk to milan03, the OP of this reddit thread and author of the previously linked article: https://www.reddit.com/r/tmobile/comments/5vrwsm/pixel_xl_four_months_later/

256qam is possible within the Pixel, but I have my doubts Google will enable it.

256qam is only enabled for Telstra right now.

A video I've seen of a TMO S7 on 256qam was just 1xCA, so not sure.

I have tried and tried to find an engineering screen in the Pixel but no luck.

I have NSG 1.2.3 still, which is the version before the purchases were implemented. I can band lock with it. I've uploaded the apk to apkmirror.
[Google Pixel XL Questions & Answers] xdadevnube:
It's longshot, but it might be worth a shot to try the 'Nexus 6 LTE Engineering Mode' APK. I don't have a Pixel yet to try it with.

Thanks for the link to that thread, I'll be checking it out.

I also have been on NSG 1.2.3, and confirm band locking works on the HTC m8 and LG G4. However, I think the only way to do PCI Locking is to pay for the in app purchase of the updated NSG app. I figured out how to PCI Lock with Samsung's Service Mode, though.

Have you tried using the search feature of Shortcut Master? Perhaps it could yield access to an Engineering screen (worth a shot).

NSG certainly makes the Pixel far more appealing, I really get tired of trying to ROM and debloat Samsung devices, ugh!
[Google Pixel XL Questions & Answers] cstark27:
I tried Nexus 5 Field Test Mode and IIRC it wouldn't get past an Unsupported Device message. Nexus 6 Engineering Mode crashes when clicking either option.

I guess I wasn't sure what you meant by PCI Locking. I looked it up on NSG's site and can't get anything to come up by long pressing on a PCI in the LTE table.

I have tried to look through every hidden activity with Nova Launcher's Activity widget (which should be the same as the app you suggested). There are a couple Sprint debug-type apps but listed no helpful info.
[Google Pixel XL Questions & Answers] xdadevnube:
I believe the PCI Lock feature is only available after the in-app purchase, except its like $50 for 30 days I think. If they offered a lifetime subscription, I would buy it even if it's expensive. I don't use PCI Lock often, but it is quite a useful feature.

I'm out of ideas regarding accessing an Engineering screen. :(

Thanks for sharing your attempts though. With NSG on the Pixel, I don't think I'll get another Samsung phone!

I am also curious if the device can access QXDM or DFS through the debug port, but I do not yet have a Pixel to try it out. There is a thread in Pixel Q&A about this.

As far as 3X CA, it sounds like we are at the mercy of upcoming updates.
[Google Pixel XL Questions & Answers] vivanshah:
march factory images are up, installing it now
[Google Pixel XL Questions & Answers] cstark27:
No change for me.
[Google Pixel XL Questions & Answers] vivanshah:

[Google Pixel XL Questions & Answers] dpw2atox:
Just curious if anyone has tried submitting this as a bug report to google or not. I'm not sure how else we can get them to address this.
[Google Pixel XL Questions & Answers] cstark27:
I've done maybe 3-5 "feedbacks" from the phone and started a thread on their own forum: https://productforums.google.com/forum/#!topic/phone-by-google/C04ACMHAYX8;context-place=topicsearchin/phone-by-google/category$3Ahelp-troubleshooting

I also believe BGR did an article on it and said Google hasn't responded to their inquiry.

But, there is an update in the Play Store called Carrier Services. I just downloaded it and will check later today, but I think it's maybe just RCS stuff.
[Google Pixel XL Questions & Answers] smallsmx301:
Yes please let us know. I think it's just RCS related as well
[Google Pixel XL Questions & Answers] cstark27:
Well it's looking like the app is just a placeholder for now.

http://www.androidpolice.com/2017/03/13/google-carrier-services-moves-play-store-absolutely-nothing-now/
[Google Pixel XL Questions & Answers] xocomaox:
It appears to be an issue with T-Mobile and not the phone. I guess big John Legere will need to step up here.
[Google Pixel XL Questions & Answers] smallsmx301:
Actually it's on both ends but no one knows who's to blame. The carrier profile on the pixel needs to be updated for T-Mobile. Google needs to update it. So is Google not updating it or is T-Mobile not providing the necessary information. My guess is Google isn't updating it for some reason.
[Google Pixel XL Questions & Answers] cstark27:
How so? If I understand Cellular Insight's report correctly, even in their lab test (with their own "radio tower") they are seeing the actual phone report to the basestation that it is only LTE Cat 6. But the question may be worth asking to Neville Ray. I don't have a Twitter so I'm out for that task.
[Google Pixel XL Questions & Answers] xocomaox:
In either case, T-Mobile would have to provide something to Google whether it be information needed to update the carrier profile OR that everything has been provided and the issue needs to be fixed for their customers. I see this as being in T-Mobile's lap as it's their service. They haven't, to my knowledge, said anything official about the Pixel working on their network with 3x.
[Google Pixel XL Questions & Answers] smallsmx301:
Who's to say that TMO hasn't given this info... I've had every Nexus on TMO and never had features not function on their Network. Volte worked flawlessly on those devices and doesn't on the pixel
[Google Pixel XL Questions & Answers] xocomaox:
Nobody has, and that was the point I was trying to make here.
[Google Pixel XL Questions & Answers] smallsmx301:
3x works on Verizon. The phone is capable of it.
[Google Pixel XL Questions & Answers] dpw2atox:
I just saw an article on Android Central saying 7.1.2 is coming out around April 3rd and "should" include VoLTE for Rogers, Rogers is apparently testing the service and Google will be enabling it in the final 7.1.2 as it's not available in the beta. That means to me that we should be pushing T-Mobile's network engineers to work with Google to test 3x CA support for the pixel so it can be enabled in a future update. Time to start tweeting John Legere.
[Google Pixel XL Questions & Answers] smallsmx301:
There's also been speculation that Google isn't activating 3x and 256qam because they have been advertising only on Verizon. Which is why it is fully functional on Verizon but not TMO
[Google Pixel XL Questions & Answers] DR3W5K1:
You know they are in some sort of contract because of the exclusiveness. Wouldn't be surprised if they were purposely giving Verizon an advantage. What's good for Verizon's bank roll is also good for googles
[Google Pixel XL Questions & Answers] smallsmx301:
But usually the exclusivity is limited. The Galaxy nexus was short lived as a Verizon exclusive. April would be 6 months. Hopefully that marks the end of it. If this is how Google is going to play the game this will be my last Pixel. I love the device but there's no reason to handicap it to certain carriers
[Google Pixel XL Questions & Answers] cstark27:
Don't forget 3xCA works on AT&T, and of course Cricket. I haven't seen anyone talk about it on Sprint, though.
[Google Pixel XL Questions & Answers] smallsmx301:
Anyone see if it works on a Lineage based ROM? I know it probably won't make a difference but it is a CAF ROM
[Google Pixel XL Questions & Answers] cstark27:
Definitely something I've wanted to try, but I am waiting for the official release.

One more thing, in one of the config files for TMO, it does list CA bands, so I don't think it's maliciously done, and just an oversight on the modem side perhaps. I would assume that's where they are defining what carrier activates what LTE category (remember, when a TMO sim is inserted, Cellular Insights/Milan found that the phone only reports as a LTE Cat 6 device).
[Google Pixel XL Questions & Answers] smallsmx301:
Ha! A bunch of mumbo jumbo I don't understand. I get that the last lines are all the bands supported. Well with the new carrier services app rolling out hopefully that means something is coming down the pipeline.

---------- Post added at 02:47 PM ---------- Previous post was at 02:33 PM ----------

Is that file available to be looked at on a GS7? Can you compare the two and edit the file to possibly get it to work? I think the gs7 has 3xCA
[Google Pixel XL Questions & Answers] cstark27:
Tried an Unofficial LineageOS 14.1 (build 3-16-2017) and still 2xCA. Just FYI. I'll probably just get a G6 or S8 in a month or so at this point. My LTE at work is pretty slow (~1-2mbps) but my coworker with a OnePlus 3, on T-Mobile, gets 5-6mbps which is more usable. And that's still on 2xCA on both devices. :\
[Google Pixel XL Questions & Answers] smallsmx301:
I would at least wait until the 7.1.2 update to see if anything is resolved before jumping ship
[Google Pixel XL Questions & Answers] cstark27:
Is anyone still on the beta? New update is rolling out for it. I can load the beta up if I need to, and test tomorrow. The image isn't up yet, though.

Edit nevermind. I just re-enrolled and was offered the new update. Will report back tomorrow.
[Google Pixel XL Questions & Answers] smallsmx301:
Keep us posted. The new radio seems much better. At work I'm on LTE like I was with previous devices. Up until this new beta I was always on H
[Google Pixel XL Questions & Answers] cstark27:
7.1.2 beta 2 (NPG47I) still just 2xCA at my test site.

[MENTION=6699638]smallsmx301[/MENTION]

Saw 1 other report so far that the user now gets LTE at home.

If you go to the dialer and type *#*#4636#*#*, go to Phone Information and scroll to the bottom, what does it say for EARFCN on the first line that starts with "S"?
[Google Pixel XL Questions & Answers] smallsmx301:
2300, your referring to the number directly below?
[Google Pixel XL Questions & Answers] cstark27:
Yeah, right under EARFCN. Thanks. Looks like that should be Band 4. The other user told me a Band 2 EARFCN. Interesting because one of the recent commits, applied a signal indicator boost to B2 and B4, but it was supposed to be VZW only...

Also, if anyone is wondering, the O DEV preview released today contains the same baseband, so don't expect anything different probably.
[Google Pixel XL Questions & Answers] cstark27:
No 3xCA on N2G47E (7.1.2 April stable OTA)
[Google Pixel XL Questions & Answers] smallsmx301:
I don't think it's coming via OTA..... Probably the carrier services app
[Google Pixel XL Questions & Answers] Up8QSky:
I may be wrong but I think the carrier service app is for RCS
[Google Pixel XL Questions & Answers] smallsmx301:
Well it says advanced features.....RCS being one of them
[Google Pixel XL Questions & Answers] cstark27:
Someone on Reddit asked Neville Ray (T-Mobile's CTO); his response: https://twitter.com/NevilleRay/status/849107326250270720

Just adding the info, I think most of us realize this already.
[Google Pixel XL Questions & Answers] smallsmx301:
At least we know who to blame. It's been 6 months and I don't think we are getting this feature. Is Verizon the only carrier this works on?
[Google Pixel XL Questions & Answers] jova33:
VZW, Cricket, and AT&T. The international version works on other networks that do have this. Just Sprint and T-Mo are left in the dust on this one.

Edit:

Also, it there a way to enable 3xCA with an unlocked bootloader?
[Google Pixel XL Questions & Answers] cstark27:
MAYBE with the Qualcomm diagnostic programs (QXDM?) but I'm not sure. It sounds like we'd need to change the configuration so that when a 310-260 sim is inserted, the LTE (UE) Category is set to 12. Second hurdle is Google stripped the debug mode from the production builds.
[Google Pixel XL Questions & Answers] smallsmx301:
I harassed customer support yesterday via built in app. They had no idea about anything. It's sad really
[Google Pixel XL Questions & Answers] kolyan:
So basically Google along with it's Project Fi are advertising 3xCA but it doesn't work? Isn't that like illegal or something? There are 2 class action lawsuits against Nexus phones already.....Maybe another one coming
[Google Pixel XL Questions & Answers] jova33:
Details on the lawsuits?

Just got my Pixel XL today, and wondering if this issue has been resolved.
[Google Pixel XL Questions & Answers] smallsmx301:
Sure hasn't. I think Verizon is the only one it works on
[Google Pixel XL Questions & Answers] cstark27:
"Supports up to CAT 12 (600Mbps DL / 75Mbps UL) depending on carrier support"

Pretty sure only Sprint and T-Mobile are limited to Cat 6 (2xCA).

I got Qualcomm modem diag mode working but couldn't find a difference between the values when a TMO sim and a Cricket sim was inserted (3xCA worked with the Cricket sim). So I'm giving up on the endeavor and hoping 4x4 mimo, 256qam, 3-4xCA, B71, LTE-U is all enabled on Pixel 2. ;)
[Google Pixel XL Questions & Answers] kls629:
Any updates with new may update?
[Google Pixel XL Questions & Answers] cstark27:
Just curious if anyone here has tried a MetroPCS sim or other T-Mobile MVNO?
[Google Pixel XL Questions & Answers] smallsmx301:
No. I wouldn't expect any changes on this device. If it hasn't been activated at this point I wouldn't expect it to which is lame.
[Google Pixel XL Questions & Answers] Xx-Ness-xX:
3x CA is still disabled in June security update 7.1.2 (NKG47L, Jun 2017, T-Mobile, Fi carriers, and Rogers)
[Google Pixel XL Questions & Answers] smallsmx301:
Yes, all that will work...... With only Verizon, since they will be the supporting carrier. Just like it is now. If google pulls this **** again it might be my last Google phone. The essential phone looked promising until it became a Sprint exclusive
[Google Pixel XL Questions & Answers] cstark27:
Android O beta DP3 (only one I've checked since root has been available for it) has 3xCA.

And I find this out the day my U11 comes...lol.
[Google Pixel XL Questions & Answers] smallsmx301:
Isn't that a *****.... Thank you for testing for us.... Looks like Google is getting everything right for the pixel 2
[Google Pixel XL Questions & Answers] Xx-Ness-xX:
By the way, flashing the radio image of Android O Beta DP3 will not enable 3xCA for those are curious. This will save your time from flashing the image. Although you can still flash it, the phone will still work just no 3xCA.
[Google Pixel XL Questions & Answers] lkhafra:
What about EVS?
[Google Pixel XL Questions & Answers] aholeinthewor1d:
I thought it was enabled in DP 3? Doesn't that mean it's coming?
[Google Pixel XL Questions & Answers] cstark27:
You quoted a 2 month old post :P

I've got the Pixel community manager "looking/digging into" 256QAM so hopefully that gets fixed as well - from what I hear, it should be an even easier fix. It really helps download speeds when I compare a HTC U11 to the Pixel.
[Google Pixel XL Questions & Answers] daddylonglegs:
Hey, I am going nuts with this too. When I download the .zip from Google's official website of the firmware/update, I have an option to download a completely generic zip (NJH47B) or one "meant" for T-Mobile (NKG47L).

Considering I never had the T-Mobile version installed (I bought the phone from the Google store), which one should I choose? What differences could there possibly be? I am confused because there is no "T-Mobile/Rogers/GoogleFi" versions of the phone like there is for Verizon, so why does Google offer specific firmwares for T-Mobile customers?

Is it possible that installing NKG47L (TMobile version) would result in 3xca working?
[Google Pixel XL Questions & Answers] cstark27:
That update for June 7.1.2 does not contain the 3xCA patch/fix. Currently only the O beta DP3 contains it. I will be rolling back to the July 7.1.2 update when it hits, to see if they are going to roll it back but since O is only, what, 2 months out, they may just leave it on O.

Anyway, that specific T-Mobile update fixes the silent ringer when someone is calling you when your phone is on Wifi calling.
[Google Pixel XL Questions & Answers] smallsmx301:
There's no way to patch 7.1.2?
[Google Pixel XL Questions & Answers] cstark27:
Beats me. Haven't tried it personally, but one person (I forget who) claimed to have flashed the O baseband to 7.1.2 and didn't see 3xCA.
[Google Pixel XL Questions & Answers] smallsmx301:
I read that too. So it's more than just the radio
[Google Pixel XL Questions & Answers] daddylonglegs:
Thanks so much for the helpful reply! So there's no such thing as a "T-Mobile version" of the Pixel, right? I wonder why that silent ringer fix wouldn't just be part of the generic update then?

Also I am lost a bit. You're saying with Oreo you get 3xca with T-Mobile? If so, that's awesome.
[Google Pixel XL Questions & Answers] cstark27:
Flashing the O DP3 radio image onto June 7.1.2 update (NKG47L) enabled 3xCA for me.
[Google Pixel XL Questions & Answers] smallsmx301:
Really? I need an unlocked bootloader to flash a radio
[Google Pixel XL Questions & Answers] cstark27:
Yep. Same for July patch.

No, the July 7.1.2 patch does not include the updated baseband.
[Google Pixel XL Questions & Answers] lkhafra:
Oh crap finally!!!

Have you tried with any custom roms from June?

I would but I stay unrooted to use Android Pay
[Google Pixel XL Questions & Answers] cstark27:
I have not. I prefer to stay on stock.
[Google Pixel XL Questions & Answers] aholeinthewor1d:
I'm running latest PN which is based on the June update. Really curious if I can flash the radio from the DP. Has anyone on T-Mobile noticed a difference with 3XCA? What exactly would it help with
[Google Pixel XL Questions & Answers] cstark27:
The O DP3 baseband is here: https://drive.google.com/file/d/0B5tsf-_V_ltYX3dxVHR1NU9OTDA/view?usp=sharing I can't say if it will work on custom roms - haven't tried any. More "carriers" can help in congested areas or to reach a higher top speed. The tower you are connected to has to support it though, and you have to know beforehand otherwise you won't know if the phone isn't working right when you look in NSG, or if the tower just isn't upgraded for 3xCA.

Also, I've seen some quotes that 256QAM would add theoretically, about +33% to your speeds. Caveat here is you need to be relatively close to a tower for it to connect at 256QAM (about a block away).

My real world example is below. Left picture is June 7.1.2 update with 2xCA. Right is O DP3 with 3xCA.

On the next picture, you can see the total Throughput at the top left (99mbps). On the right side you can see the throughput for each "carrier" on the bottom, next to PDSCH Tput. Take one of those away, roughly, to get an idea of the benefit of 2xCA versus 3xCA.
[Google Pixel XL Questions & Answers] aholeinthewor1d:
Thanks. Gonna tty flashing on Pure Nexus today. Can you give me the steps to flash and also once I do how can I test to make sure 3xCA is working? Thanks!
[Google Pixel XL Questions & Answers] aholeinthewor1d:
Is this correct? According to others it would enable 3xCA?

EDIT: Just flashed the DP3 radio while running latest Pure Nexus. 3xCA is working for me on T-Mobile! Haven't been running speed tests often to give a good comparison but I've never seen these speeds in the past at my house.. 92 Mbps
[Google Pixel XL Questions & Answers] cstark27:
I have found that post you quoted to be incorrect. Unfortunately I believed it for too long and didn't bother testing it myself and stayed on the O beta too long until I grew tired of the poor battery life. Proof has already been posted at the top of page 12. Good job on figuring out how to flash the radio. :)

If you have root, download Network Signal Guru. Open it, then go start a speed test, while it is running, switch back to NSG and look at the red letters at the top left. Again, you must know that your test location supports 3xCA. I usually verify that with T-Mobile devices like S7, S80, V20 as they support 3xCA and have built in engineering modes that provide that info. By the way, you will only see 2xCA or 3xCA when you are downloading something. To conserve battery, the modem doesn't constantly stay connected to those multiple cells.

And hopefully you are right that it's enabled for you. I had never seen above 60mbps on my Pixel, even given the best conditions like testing at 4am. I have found a few spots now that I can get a little over 100mbps even at 4pm so it's pretty nice. Just makes my phone feel a little more worth the money. Especially since the OnePlus 5 already supports 3xCA and 256qam lol.
[Google Pixel XL Questions & Answers] aholeinthewor1d:
Yea I have network signal guru and as soon as I open it, it begins testing and does in fact show 3xCA at the top so its working
[Google Pixel XL Questions & Answers] xocomaox:
Just to be absolutely sure, that modem is for sailfish but it's the same for both models, correct? I'm going to try it on the latest Dirty Unicorns and see if it works.

Thanks for the info and link!
[Google Pixel XL Questions & Answers] Golf c:
Not really that exciting. Had to travel 30 minutes to find a tower. Running Dirty Unicorns rom with DP3 radio.
[Google Pixel XL Questions & Answers] cstark27:
Yes, sorry, that is for the 5" Pixel. I would think it would work on both models but I can't guarantee it. To be sure, go ahead and download the latest factory image for 7.1.2 for Marlin and extract the baseband if you need to revert.
[Google Pixel XL Questions & Answers] Xx-Ness-xX:
For whatever reason I have not seen 3xCA enabled on my Pixel while on DP3 radio. This is most likely due to not seeing the towers. I am sorry if I mislead some of you, I was just telling you what I saw based on my real world live test. For your information, I live in Chicago and according to T-Mobile 3xCA is available here.

Anyway, now it is confirmed that flashing DP3 radio would enable 3xCA, just make sure you are also in an area where it has 3xCA enabled
[Google Pixel XL Questions & Answers] Golf c:
It does appear that I have to be downloading something (a speed test) to trigger the 3X carrier in Signal Guru to show up.
[Google Pixel XL Questions & Answers] xocomaox:
Flashed the modem from Marlin factory image. Good to go on DU 11.5. ?
[Google Pixel XL Questions & Answers] kontogis:
So I downloaded the file linked in here. I honestly have no idea what to do from there. I can follow directions if someone could point me in the right direction I would appreciate it.
[Google Pixel XL Questions & Answers] kontogis:
If I am reading correctly. I need to unlock the bootloader boot into the bootloader and then fastboot the img file from said zip file. Is this correct?
[Google Pixel XL Questions & Answers] xocomaox:
Yes.

Once in bootloader, run the following fastboot command from your PC:

fastboot flash modem modem.img (or whatever you named the file)
[Google Pixel XL Questions & Answers] kontogis:
Sweet thanks.

Just didn't want to do something wrong and mess it up.
[Google Pixel XL Questions & Answers] cstark27:
Maybe it's the same result but the command I actually used was:

fastboot flash radio radio...img

There is a separate modem file actually called modem.img, in the factory image but that did not seem to matter, and that one should use the "flash modem" command. But like I said, maybe it's the same result...I don't know.
[Google Pixel XL Questions & Answers] aholeinthewor1d:
Someone else said the same thing but as soon as I open network signal guru it shows 3xCA with nothing downloading
