Nexus 5X H791 without B28 band, locked for some carriers - Nexus 5X Q&A, Help & Troubleshooting

Well, after reading and reading and reading i found this problem in my Nexus 5X H791
Here in Chile, we use 2 bands for LTE
- B7 2600 Mhz (outdoor)
- B28 700 Mhz (indoor)
The B28 have excellent signal here in my city, and i bought my 5X because is compatible with all the bands (included B28, in theory)
But always I'm only in 3G.... my sim card is the problem. I changed it and nothing!!!
Next, I put my sim card in an iPhone 6 of a friend of mine..... 4G LTE without problems!!!!
Then, someday, in the google's forum I found this that mentioned the problem https:// productforums.google.com/forum/#!topic/nexus/-6UeSgrWJfg
The Nexus 5X is only compatible with a few carriers in the B28 band. Inside the baseband archive (radio.img) are another archive and mention what carriers are fully compatible with this band, without my carrier obviously (730-01 entel Chile)
The Nexus 5X H791 is locking the B28 LTE band by software!!!!
Any solution??? I think the only possible solution is that Google in a next update erase that problem in the baseband.

No one?? What have to do??
This is important for me!!!

God damn app flash and desktop picture sharing fourm,I think there will be NO ONE help you on this question,as such an problem overscaled his mind at skyhigh level,
so entel Chile right?Band 28A or Band 28B?,seems like it's hard to find some information about your country's carrier,this frustrated phone only support Band 28A(Lower Duplexer) as japanese find
これはBand 28には大きく「Lower Duplexer」と「Upper Duplexer」という2つの周波数帯が存在しており、NTTドコモの説明によると、Nexus 5XはBand 28のLower Duplexerのみに対応しており、Upper Duplexerには非対応で、日本の3社のBand 28はUpper Duplexerに該当するためであるということです。
Band 28のLower DuplexerおよびUpper Duplexer、日本のNTTドコモおよびau by KDDI、ソフトバンクの各周波数帯は以下の通り。この仕様からすれば、Nexus 5Xではau by KDDIのBand 28は利用できるものと見られます。
周波数帯 下り 上り
Band 28 Lower Duplexer 758.0~788.0MHz 703.0~733.0MHz
Upper Duplexer 773.0~803.0MHz 718.0~748.0MHz
NTTドコモ 783.0~793.0MHz 728.0~738.0MHz
au by KDDI 773.0~783.0MHz 718.0~728.0MHz
SoftBank / Y!mobile 793.0~803.0MHz 738.0~748.0MHz
If your carrier not implement in such frequency range,ther will be no chance of using such band
Ooops,there is a simple method test,install https://play.google.com/store/apps/details?id=com.qtrun.QuickTest
remove SIM,OPEN APP and lock RAT to LTE,lock band to B28(unselect others),then wait for the signal,screenshots will be very helpful

F400S/K/L Versions (Hardware Comparison) and usage on AT&T

Hola folks!
After finding enough screenshots/video reviews, I am beginning to think that from a hardware perspective the S and L variants are identical (including supported bands), whereas the K is only slightly different from S/L.
Any images of the back cover off on the K models (Olleh) will show "F400 0425 K" indicating the hardware is the "K" variant. (If you watch the review video http://www.androidcentral.com/lg-g3-review, you will notice this info up at the top on the backside, right above the camera.) UPDATE: Here is another link with an image http://arstechnica.com/gadgets/2014/06/lg-g3-review-a-great-phone-with-way-too-many-pixels/#image-4
On the S/L (SK Telecom, LG U+) models, they say "F400 0423 S/L" on the SK Telecom model ("S" variant), and "F400 0425 S/L" on the LG U+ model ("L" variant). You can find images of the "S" model with engadget's review (http://www.engadget.com/gallery/lg-g3-review/2676959/#!slide=2676963), and images of the "L" model with ubreakifix's F400L teardown (http://www.ubreakifix.com/blog/wp-content/uploads/2014/05/ubif-g3-21.jpg).
(Thanks and kudos to the review sites and teardown site for the images.)
As an owner of the F400S, I can tell you that all 3 variants will run on AT&T LTE (as a lot of our LTE is on Band 17 - 700 MHz spectrum). I was able to load my F400S with the TOT and DLL files of all 3 variants (currently waiting on getting it back to the "S" variant once the DLL is posted), and all 3 variants will connect to AT&T with no issues (for those of you that plan on importing like I did).
So for those of you who managed to brick your new G3, as long as you can ADB into it, you can edit your build.prop file with the corresponding korean variant model info, and load any stock image. As @wolfgart has posted a great thread with the TOTs and DLLs, I recommend swinging through there for more info. If you have a K variant, load the K TOT and DLL, and you are fine.
For those of us with S/L variants--with the above info and enough tinkering in the hidden menus of all 3 variants, I can tell you that from a hardware perspective these two models are nearly identical. From a modem/supported frequencies perspective, the S and L variants support the exact same frequencies--meaning, if you bricked your S or L version, you can restore it with an S or L TOT and DLL (after editing build.prop if needed) and you will still get all of your original hardware supported bands/frequencies. This is critical for those of you using LTE Band 5 to connect to your data... (should not be the case for any US AT&T users...).
UPDATE: in the 'Android Development' section, wolfgart's thread with the TOTs and DLLs have been updated to now include the files for all 3 models. So unless you know what you are doing with a build.prop edit, probably best to stick with what came with the phones for those who are new to this stuff.
The main difference between the S/L and K phones in frequency/band support is that LTE Band 8 is supported on the K model only, whereas you will get LTE Band 5 support on the S/L models. All other bands and frequencies (WCDMA/GSM) are the same across all 3 models. All 3 also support LTE Band 17, and will connect to AT&T in the US.
Took me a while to figure this out, but I had a long weekend
Cool! nice to know, thanks for the well explained post
Any thoughts about the L/S version suporting LTE Band 7?

Unfortunately, I don't connect to LTE with band 7 so I can't say much on that. However, just based on the hidden menus in both (I am using the L version on my S variant phone at the moment), they both have the same listings of 1,3,5,7 for supported bands.
LTE 700, 850, 1800, 2100, 2600 (Band 17, Band 5, Band 3, Band 1, and Band 7 respectively)
UMTS 850, 1900, 2100
GSM 800, 900, 1800, 1900
The above are the fully supported bands on the S and L variants.
The below are the fully supported bands on the K variant.
LTE 700, 900, 1800, 2100, 2600 (Band 17, Band 8, Band 3, Band 1, and Band 7 respectively)
UMTS 850, 1900, 2100
GSM 800, 900, 1800, 1900
I don't have the K variant on my device now, but I recall the only band difference is that it supports LTE band 8 (900 MHz) instead of LTE band 5 (850 MHz), but other supported bands are the same. LTE Band 5 is one of the primary bands for both SK Telecom and LG U+ (which partially explains why the two phones have nearly identical hardware, including modem support).
Hope this answers your question. As support for those frequencies are built in (and it makes sense on LG as a mass manufacturer--They can use the same modem and just rebrand it like they did in Korea for the S and L variants).
Why is the S one more expensive than the L?

That, my friend, is a question you will have to ask LG and SK Telecom. We sorta see that in the US every so often with "special editions" that aren't really that special and they will add an extra 100ish.
Off-contract, LG U+ is the most affordable right now, with SK Telecom right around $700 USD. With markup and shipping, etc. eBayers are selling it for $750-800.
Also, you have to remember the G3 is a hot commodity even in Korea right now. Had some friends who thought it was funny I got a phone overseas before they even bothered joining the bandwagon.
So though I can't say for sure why exactly it's more expensive, I can definitely say it has to do with the fact that the phone is still only 3 weeks old
And none of those 3 will work on T-Mobile LTE which needs 1700 and 2100Mhz most of time.
There are some spots with 900Mhz support though.
But as much as I want G3, I'll wait for the T-Mo version.
Yeah...I'm a proud owner of a Htc One M7...I have been thinking a lot and decided that it's time to change. I'm comparing the M8, the Z2, the G3 for a long time and finally think that this last one will be the one...unfortunately it's still very soon to easily find information regarding this phone online...
Your information helped me a lot...now I know exactly which variant to buy :fingers-crossed:...thank you guys very much

It looks like you are planning on doing the same upgrade I did. I still have my M7 as my backup , but definitely gotta say I am loving my G3.
That's amazing man...I've been a HTC fan since the Sensation...but currently I feel that they are been left behind...
I'm really sorry, but other brands are offering a lot more for the same price.
The HTC will always win in design and the quality of the phone's body, screen and, of course, sound!...but they are losing in the rest...UI, camera, battery life definitely...it's just sad
Nice to know that you're enjoying your G3...I hope I'll be as happy as you are in a few weeks...and judging by how much I've researched about it...I'm sure I'll love it!!!

question
sorry, which of these three variants brings FM radio? K, L, S, and if for example buy the K version, if you install the L or S variant fm radio works?
I´m about to buy a G3 and found some model have an antenna, is that correct?, anybody knows what tv frequencies can handle?. Thanks!

From my research, none of the korean models (F400 S/K/L) support FM radio. Instead of an FM radio tuner, they are offered with Korea's DMB tuner, for korean DMB support.
I have only seen DMB function while in Korea and Japan. Anywhere else in the world, you will have to check with local providers, as some countries will charge for DMB as a service (just like satellite television).
Hope this helps

The only frequencies it can support is anything broadcasted as DMB. Certain countries offer DMB subscription services, but you will have to research if it is offered where you live.
In the US, DMB is unavailable so I just have a nice long antenna that people crack up at in the year 2014, but completely unusable where I am. I just tell them its for better service as a side joke lol

Any of them will do. I would say go for the one that gives you the best price. At this point, enough AT&T users have gotten their hands on all 3 variants. Most can get LTE through band 17 (700 MHz) which is available on all 3 phones.
Will the D855 variant (with LTE 700MHz) be able to use on AT&T (band class 17) or Verizon (band class 13)?
Or to be more specific, will the D855 cover all 700MHz US band class (12, 13, 14, and 17)?
Thanks!

You would have to check which specific band class of 700 MHz the D855 would be capable of connecting to. As I do not have the D855, and specs are varied on the internet right now, I cannot say for sure.
The FCC had ruled four separate band classes to operate on the 700 MHz spectrum in America--Band 17 700 MHz capable modems cannot connect to any of the other 700 MHz band classes and vice versa. (It was claimed that they did not want to have any network interference issues. Carriers purchased the rights to access certain chunks of the 700 MHz spectrum, and they are isolated to those carriers only.)
I am seeing 700MHz (B28) support on D855 models, but I believe that might be related to certain LTE-A rollouts in Europe (meaning it may not be able to connect to current 700 MHz bands in the US (as the US does not have LTE-A networks at the moment) and new band classes are issued for LTE-A (i.e. Band 28).

Does a Nexus 5x from USA work in Europe / Germany

Hello Guys,
does anybody know, if a Nexus 5X, which I want to buy on my next visit in USA will work in Germany?
As I heard the US Providers do not use SIM cards.
Thanks for your help.
SLC_SHARK
We DO use SIM cards. Only 2 carriers don't.
I believe the phone should work fine over there.
In europe lte bands 3,7,20 are used to provide 4g connectivity.....I believe the american model doesn't have lte band 20, as long as your carrier supports also band 3 and 7 you should be fine or at least with worse coverage
It works fine, your only problem might be LTE not working due to the different bands.

BND-L24 USA LTE Bands question(s)

Reference phone specs at end. I recently got the Honor 7x and am using T Mobile in the Atlanta, GA US region. At home, when I got the phone Friday night after work it was awesome. Super fast no problems plug and play. But Monday at work I get full signal, but no internet. No download speed. I found that when I go into the settings under mobile network if I choose preferred network mode down to wcdma/gsm it turns off the LTE but I get some data. Is there a way to remedy this problem without having to sacrifice LTE while I'm at work?!? I know the Huawei website says the phone works with T Mobile, but if it only works with 3/5 bands do I just not get LTE where those bands are in effect? Can someone shed some light on this? Because before today, I honestly didn't know what any of this meant. Thanks in advance!
Phone Honor 7x
Model BND-L24

Miguel EsquivelHi there! Thank you for reaching Honor Device USA. How may I be of help today?
Sam8:40 pm I'm having trouble with my signal for my phone, and I'm also having a difficult time finding information on my situation with the US version of the 7x. I have L24 version, and I also have T Mobile. am I unable to get 4g?
Miguel Esquivel I see, let me help you with that
I am sorry you are havinf this issues Sam
Can i please have your imei number
Sam ...
...
Miguel Esquivel Thank you just a moment please
Thank you very much for holding Sam
Sam of course
Miguel Esquivel Can i please know who is your carrier?
Sam t mobile
Miguel Esquivel Thank you
Can i please know what issues are you having regarding the carrier signal?
Sam well, when preferred network type is set to LTE/wcdma/gsm auto and 4g is enabled, i get a full signal as far as bars go and the 4g icon is there but my download speed is nothing and it tells me im offline
when i change preferred network mode to wcdma/gsm i get data, but not 4g
Miguel Esquivel I see
Have you try a diferent sim card?
Sam sim card works in other phones fine.
Miguel Esquivel Thank you for that information
Does this happen everywhere?
Sam mostly seems to happen when I am at work
i work in...
live in...
Miguel Esquivel well it seems to be intermittent issue, but since your satisfaction is our main goal we can send the device to our repair center for further testing, but if you allow me to add my opinion i think that the signal goes weeker on that location and probably does not reach enough power to have data traveling on it
I do not have a coverage map for your carrier i am sorry, but you can consult them, it could also be a sensibility related issue with your antenna Sam
Sam i'm showing that there are 2 bands that the honor 7x does not support that tmobile does use and im just wondering why we aren't on the same page
it's not a repair issue. it's a matter of whether or not the phone is compatible, and i'm leaning towards no unless you have a solution. there are 3/5 supported LTE bands for this phone which i did not think would mean that LTE wouldn't work at all
Miguel Esquivel This are the frequency bands compatible with the L24 A
Primary SIM card:
4G LTE FDD: B2/B4/B5/B7/B12/B17
3G WCDMA: B1/B2/B4/B5;
2G GSM: B2/B3/B5/B8
Secondary SIM card (voice services only, no data service):
2G GSM: B2/B3/B5/B8
Sam so if T mobile uses B66 and B71 LTE bands for their LTE service as well and the honor 7x is incompatible with these my phone will not work properly unless i completely turn off LTE????
Miguel Esquivel I am afraid the service could be intermittent Sam
Sam so depending on where I'm at, I need to stop what I'm doing go to settings and turn off LTE data in order to get ****ty 3g data just so I'm not stranded? Read
Miguel Esquivel I am sorry Sam
Miguel Esquivel has closed the chat.
Lte does not work for me in Canada with freedom mobile too.. Honor and waway does not give a **** as usual
Okay, forgive me for this, but what was advertised that isn't working?
T-mo will be the first to tell you that not all of their services are available everywhere, is that what's going on here? I may be missing something here, but does the honor / huawei not work when a different device (with the same bands) would work?
Honestly, just a question, I really don't know...
Lte band 4 and 7 were advertised and does not work on my carrier..
the same problem here. i'm in venezuela, band 8 UMTS were advertised on the specs phone and doesnt work
Phone Honor 7x

The 900 band you want to use isn't available on the BND-L24 model
Works great on at&t even in areas near here that have gotten worse service recently.
Bands 5 and 12 are the main T-mo bands so it should work for you, bud. I would double check the APN. I would also have T-mo release the SIM and reprovision it (cut it loose from the network and reconnect it); I used to work for T-mo and this can resolve a buttload of connection issues.
I use mine on Cricket/AT&T and get better reception than I did with my ZTE Axon 7.

Force H790 to use specific LTE bands

Hello, I'm having troubles to use the WOM carrier over Chile, as the other carriers uses the LTE band 28 and it is supposed that my Nexus 5X doesn't have one, I'm force to use that carrier which use the band 4 (AWS), and as stated in multiple specification websites the Nexus 5X is capable of using that band.
The problem is, even if I have good signal and I'm using "LTE" as marked by the phone, my internet connection is horrible, and almost null in any indoor place, I'm already sure the carrier is not the problem, as I tested my sim card over another phone and works like a charm.
Is there a way to check which LTE band number is my phone using?, And there is a way to force it to use the band 4 AWS?, My model is a 16GB H790, and it is not rooted but if it's needed I will do it

Question Force enable carrier aggregation outside us.

Hi everyone. Im wondering if this is possible for pixel 6 pro. Basically my unit is direct from us store which is G8VOU. Now im using it in Malaysia and 4g lte works fine.
Now im wondering if carrier aggregation is possible through root. Right now from what see through netmonster it can do 2ca on the same band(check screenshot). I think its aggregating two towers with the same band, i may be wrong though.
Anyone had any idea how to force enable multi band ca? The local sold phone can go up to 5ca which are mainly band 1, 3, 7 ,8. Thanks in advance.
I would also like to know
Is it not 4G+ an indication of currently using carrier aggregation?
Try to download NPerf app and click on speed test button. It will detect your carrier and mention it's currently on 4G+ or LTE-A
Another proof is below when you check in *#*#4636#*#* . Currently my Yoodo is on band 7 and band 3.
And Digi Malaysia only have 1 band which is Band 7
Digi - Malaysia - Wireless Frequency Bands and Device Compatibility
Digi (Malaysia) uses 2 GSM bands, 1 UMTS band, and 1 LTE band. Find out if your unlocked phone or mobile device will work with Digi (Malaysia)

Yes like is said. Mine is at 2ca indicated that im at TWO bands aggregated. Which is way below whats possible. Let me know if you have something that can help instead of just pointing out facts i already stated in the first post. Thanks.

I sometimes have band 3 and 8 as well. Just never 3 or 4ca at a time. Only up to 2ca max.
The modem decides aggregation.
