Can't find Carrier specific file download - Nexus 5 Q&A, Help & Troubleshooting

When I first got my N5, it automatically connects to AT&T LTE network, even when the LTE network has bad connection. Then someone posted a carrier specific file, that allowed my N5 to drop to 3G whenever LTE connection is bad.
I just upgraded to 4.4.3, and need to find that file again. The issue is that I forgot what keywords to search for. Can anyone help?

[Q] Internet Issues

I just got my Sensation today, unboxed it, but it won't do anything over the internet over wi-fi. I have connected it to my wi-fi router and it says it is connected with 4 bars of signal, but whenever I try to go to a webpage it brings up the Android fault screen saying "Webpage not available", it seems to do the same thing when connected through my pc (having said that, I am less sure my settings are correct for that to work).
I have moved from a Motorola Milestone, which works perfectly on the same network.
Does anyone have any ideas what I am doing wrong?
Cheers,
Dave

the only thing i can personally think is try making sure your router has all the latest drivers.....better yet...try to connect to a different wifi spot to eliminate phone or router. if, with a different known working router it doesn't work, then get worried.
I'm having similar problems. With my Vodafone sim everything works fine, but with my T-Mobile sim (which I want to use until my number is ported), I get 4 bars of HSDPA signal but no data connection and the wi-fi doesn't work.

Thanks, glad I'm not the only one. I've just tried it with my T-Mobile sim, and that has the same problems. Will probably try calling vodafone tomorrow or going in store, I hold out more hope of finding someone helpful online though. My experience of store staff is not 100% positive for technical stuff.
WiFi is good on mine although I don't get a 3g signal at all at home. T mobile sim doesn't connect to internet either but hopefully that should be because the internet settings should be changed for t mobile. I'm hoping that any issue we have can be sorted with a new radio.

You'll probably need to add new APN settings for t-mobile, as the Vodafone Sensation only has the vodafone APN.
lol that what i meant. but vodafone should have a better signal that t-mobile its struggling to keep 1 bar. hope this not one of those antenna bugs that my old tytn 2 had
I've not yet tried WiFi but my mobile data is now working fine on T-Mobile with the following APN settings;
Name: TMobile GPRS
APN: general.t-mobile.uk
Username: user
Password: pass
Enter that via the APN option in settings under wireless networks.

It looks like it is a problem with my router / network. I have managed to get wireless working on a different wireless network, so I think I need to play with my router to see if I can get that to work.

[Q] [HELP] Galaxy S3 Problems

Hello,
I have a Verizon Samsung Galaxy S3. I have rooted it about a month ago, and just yesterday switched to the AOKP rom. Everything was working well, except I have run into a couple issues.
1. Won't connect to 4G. I have a 4G data plan, and when I am out somewhere, it won't connect to 4G. Anyone know what to do?
2. I can send picture messages, but when I get them, it says "Download". I click Download, and it just loads with 0% and won't download them.
The biggest issue is the data plan not working, so I really need help with that. Thanks to whoever can help! Majorly appreciated!
-John
Can anyone help? I'm leaving for a trip soon and really need it fixed.
What modem are you running? I had data problems too until I upgraded my modem. I can't post a link yet because of my post count but if you google "verizon galaxy s3 modem" you'll find download links to flashable modems. I'm currently getting the best results with I535VRLK3 in my area. You'll just have to see which one works the best for you personally.
Also check what network you're on (I'm on a TW rom right now, so this might not be the right place to look, but... )
Settings - Wireless and Network - More Settings - Mobile Network. Make sure you're on CDMA/LTE

Also in Access Point Names make sure that you have LTE selected and not EHRPD. Some time it auto switches from LTE to EHRPD. If you notice that you are mostly in 3G it probably switched from LTE to EHRPD, at least that is my experience

sure it does if when doing your research like I did on mine I see it works on Band 4 which is T-Mobiles band for LTE. I get speeds up to 36dl and 19up with my ONe.
What are your speeds? Does your wifes Nexus show H+ and 3g symbols?

But I think I got it figured out - You are right it works in LTE - when i had 4G on screen i used the app you send me link for and that app shows LTE as network. So the bottom line is that 4G stands for LTE in stock rom and it is possible that Nexus has a stronger radio than One so in some areas i do not get LTE.
Anyway Thanks a Lot for your help - got a little worried ( Got the phone just yesterday). I think i will keep it stock for a little while before i will root it
The radio performance seems the same for me as my N5, I'm living in NYC.
Do note that "LTE" on a Nexus 5 is displayed as"4G" on the OnePlus One. Ensure that your APN is on T-Mobile 4G LTE IPv6 (fast.t-mobile.com), for some reason when I started my phone it was on MetroPCS instead.

nah root it its more fun that way and fyi they just came out with an update to 4.4.4 stock from what I have been reading. I saw this posted in earlier.... I guess you will be getting an update soon.
One suggestion if you plan on rooting and unlocking bootloader I suggest doing it now since it will wipe everything when rooting... There is a method where you wont lose data but it will not unlock your bootloader

To OP: How old is your SIM card? Have you ever received LTE signal on a previous device? I receive LTE on TMobile 4G perfectly fine, I just wish the "4G" showed up as "LTE" as my Nexus 5 did. I guess I could personally go skin it to say LTE instead but its just cosmetics.
And I completely agree with unlocking the bootloader, even if OP doesn't have any intentions to rooting/flashing, at least do it now so when you do decide to do it then you will be able to back everything up without having your device get wiped.
Edit: OP also go into dialer and type in *#*#4636#*#* then go into phone information -> scroll down -> under set preferred network type: LTE/GSM auto (PRL).

I thought the same thing (coming from a Nexus 5). I was worried that the OnePlus One did not support LTE but it definitely does. For some reason Cyanogen did not include a separate LTE icon as what's found on the Nexus 5 and most other LTE capable phones.

For sure its weird how they didn't adopt "LTE" and used "4G" instead. You can always go and change it to "LTE" with some apk hacking. Pretty easy to do.

So does your phone get "4G" now? You can verify in Settings -> About Phone -> Status -> Mobile network type -> should be LTE if the top right says "4G"
The best way to unlock/root is to NOT use a toolkit. Yeah a toolkit is easier, but honestly unlocking a bootloader is not hard and the skills you obtain by doing it yourself are important. You won't lose warranty, you can always relock it and use the bit mod and OnePlus will never know. Plus OnePlus encourages the whole custom rom scene since thats why they have a Development forum on their official forums.

I called AT&T to have the IMEI changed over to the OPO since I was on the Nexus5. CyanogenMod doesn't technically come with LTE icon, personally I can careless but it does look nice at top lol. And you're correct on my device under Mobile Network Type it shows LTE but icon on top shows 4G.
4G is LTE
H+ is HSPA+
3G is ... 3G
edge is edge :crying:
The first speed test in my sig is my LTE speeds using my OPO... Pretty typical, maybe a little faster than my old Galaxy Note 2. :good:
how does one change it to the LTE symbol?
I'm just curious. If you know 4G means LTE, whats the difference if it says LTE? Not trying to be an A-hole...just curious.
If you run the CM11 nightlies on the OnePlus One the phone will show LTE in an LTE area. Only the stock CM11S shows LTE as 4G.
I would think that people on xda are more well informed.
Carriers like to change the official terms to make you "buy" into a "technological" leap.
Most of the roms outside North America uses 4G (instead of LTE). This is all about marketing.
HSPA(+) are 3rd generation networks while LTE is the 4th generation.
back in the day:
iPhone = edge speed 2.75G
iPhone 3G = HSPA 3G (7.2) speed
iPhone 4 = HSPA+ 3.5G (carriers in north america tried really hard to change this to 4G)
iPhone 5 = LTE 4G

I agree fully with Line 1 - especially here we should do more homework before posting...
my oneplus signal is terrible compared to my n5
Sent from my One using XDA Premium 4 mobile app
mine is better then g2. Do note that your phone may or may not have the bands your provider has for lte. This you should have checked before you got the phone.
Also delete apn and reboot.
If it works better something went wrong there. If it doesnt check your providers website if setings are all correct.
If they are you might need a new sim/ or lte enabled via your provider.

3G problems on 5.0.1

Hello everybody,
I am using a Nexus 5 for a full year now and I noticed from the beginning that I never can get 3G signal, but when I am in the nearest city I van get 4G/LTE. Last week I wanted tot know more about it so I inserted my sim into another phone and immediately I had full 3G connection. So I updated to 5.1.0 with the new radio for 5.1.0 and I still couldn't get 3G. When I googled for 3g coverance I noticed I shoud've get full 3G. however only 2G and 4G works but the problem is that there is no 4G coverance in my hometown so I am stuck at the slow 2G. I'm in the netherlands and I already tried all options in *#*#4636*#*# but I still dont get 3G. also my apn settings are correct. so my last hope is to ask here if anyone knows what to do. I'll include a picture of my baseband version etc.

If it doesn't work after clean flashing factory images and trying different radio versions, it might be a hardware problem.
It's sad because I don't have any warranty anymore because I've opened the device up to replace the screen myself. Do I need to change the whole motherboard?

? How to get LTE speed on US LTE tablet running ROW LTE Image?

Hi folks,
I've got the US LTE original Shield tablet, which is the replacement that NVidia sent me for my original "pyro edition" tablet. Since ATT haven't released the Nougat (Android 7, software package 5.0 or 5.1) builds for this tablet, but the ROW tablets are able to get this update, I flashed my tablet using adb/fastboot with the full ROW 5.0 package downloaded from the NVidia site. I then connected to WIFI, and let it pull down the 5.1 update. Factory reset, flash TWRP, rooted with SuperSU. Easy peasy. Then I set up the tablet with my accounts and such.
Based on good info from user @Son-j I made two build.prop edits, changing ro.build.flavor to wx_na_do-user (was wx_un_do-user) and ro.product.name to wx_na_do (was wx_un_do). This changed the reported signal type from H+ to 4G. Unfortunately I'm having trouble finding the thread where he suggested doing this. I think it was on the geforce web forum.
The only problem I've found so far is that I'm not getting LTE speeds. I was in Chicago for a couple days, in an area with strong LTE signal, and my other devices were reporting LTE and getting ~20Mbps down / 10+ Mbps up. My Shield was pulling maybe 8 Mbps down at best , and 1-2 Mbps up. At home in my suburban location, the difference is negligible (most devices here do 5 Mbps down / 1 Mbps up, LTE or 4G).
Still, I'd like to fix this if possible. Are there further edits or flashings that will let my US device running the ROW build get LTE? I have gone in and verified that my APN settings are the recommended ones from ATT. These showed up automatically, and matched the ATT recommendations.
Thanks in advance!
Hi I'm not sure but I there was a thread here in XDA that says it's still difficult to change the LTE (RoW to US, and vice versa) bands because developers couldn't find yet which part of the code to modify... It's not also confirmed if it is indeed possible to change the LTE bands to support.
So basically, flashing RoW LTE on US LTE device will still result in US-LTE supported bands. That's what I understood.
But what you did is quite a revelation. Can anyone else confirm that modifying the build prop will work? Boy I'm excited!

Hi @Son-j -
Thanks! Do you happen to remember which thread had those two buildprop edits? I found them after seeing a post from you a few days ago, but now I can't find it at all. My google mojo has fled me.
I'd like to have a link there so others can see the original source.
It would be nice to get LTE speed, if someone knows how, but most places where I use the tablet don't have super fast LTE, so the difference for me isn't enough to make me downgrade to the marshmallow US LTE build. I'll stick with nougat for now, and hope eventually to get full speed. Who knows, maybe ATT will eventually release the 5.1 US LTE build...
For clarity here is the set of APN settings I'm using. I'm going with the column in the center at the bottom for Tablets:
https://www.att.com/esupport/article.html#!/wireless/KM1062162
All of this was correctly entered by default except I did need to edit two keys:
APN was listed as broadband instead of Broadband (yes, I'm picky, but wanted to match case)
APN type was listed as just default. I edited it to match the listed setting of: default,mms,supl,hipri,fota
Also I'm set to LTE for "Preferred network type"
Ok I think there's a misunderstanding. Uhm, I'm trying to look for the related posts here at the Nvidia threads but it seems to have disappeared.
Just to set something straight, LTE speed is influenced by:
1. LTE device with specific supported LTE bands
2. LTE sim
3. Location with LTE signals
I take it that for your specific device - US LTE Shield Tablet (just like mine) - you satisfy all 3.
For the record, flashing RoW LTE on our US device won't change the supported LTE bands (check baseband code in About Tablet section of settings). So if you used to have AT&T LTE speeds/signals using US LTE ROMs, it shouldn't change if you flashed RoW LTE ROM on the same device.
We are speculating though that there might be a way, software/firmware speaking. We are hoping it's not hardware-baked.

Thanks Son-j. It kind of freaks me out that just a week ago I found the thread that recommended those two changes in buildprop, but now I can't find it, and apparently neither can you! So maybe I'm not crazy, since it's more than just me having problems finding it.
Anyway, yes, I used to get the LTE indicator on the tablet, when in an area that has decent reception of those bands. At my workplace, which is a building built like a Faraday cage, we can get only ATT service, via repeaters spread throughout the building (I switched from Verizon in part due to this). Phones almost always report ~3 bars of LTE in places I usually find myself within the building. However, speeds tend to be <10 Mbps (tested using Speedtest.net from either my phone or tablet). So, despite getting "LTE service" there (prior to my software update), the speeds were nothing so great. For this reason, I'm not TOO worked up that my US tablet running ROW software isn't reporting LTE... most places where I use the tablet don't have blazing fast LTE, and the difference between the 4G service it actually gets and the LTE it "used to get" is not that great.
I would like to fix the problem if possible, but it's not a critical thing, and I may just put it on the back burner until the US LTE 5.1 image comes out, then flash back to that. I've got lots of other fish to fry these days.
Always interesting discussion. Thanks Son-j!

If it's just a speed issue, that will be the provider's end. If it's a signal issue, that's device problem.
It's possible to get an LTE signal but with HSPA speed in some areas.
There is an app called LTE Discovery. It will tell you which band it is currently connected to. I've got it on my tablet on T-Mobile. I am having problems with it connecting to anything other than 3G. But I have read others with the Shield tablet having similar problems with T-Mobile.

Thanks @caseyatbt,
I was unaware of that app. I downloaded it on my phone (which gets LTE just fine at my house, most of the time) and it reports all kinds of fun stuff about the LTE signal it's connected to. On the US Shield tablet running ROW stock, this is what I get, which frankly makes me think the tablet is connecting via CDMA of all things, despite having chosen all the correct options in the Settings / Mobile section:
The fact that my radio seems to be connecting to WCDMA instead of GSM is kinda freaking me out, folks.
I'm tempted to try flashing the US LTE device Marshmallow recovery image, and see if that fixes it. I understand the flashes don't change the baseband, but since I flashed 5.0 and the the device did an OTA update to 5.1, that might have changed the baseband, eh?
So, if me flashing the marshmallow files doesn't fix it, I might reflash an earlier edition and let it OTA to latest edition, which presumably would install correct "latest" baseband for the model.
We'll see ... I'm still not committed to one direction or another.
Marc
OK, I just flashed the 4.4.0 version of Marshmallow. (full flash of all Nvidia recovery image files). After letting it reboot the first time, it checked for update and found none, as expected.
NO LTE. Downloded the LTE Discovery app, and it still only sees WCDMA signals. Uggh.
Now I'm going to install the 4.3, and let it OTA to 4.4, and hope that refreshes the modem/radio. If anybody is following this, wish me luck!
EDIT: OK, I'm in idiot mode. I downloaded what I thought was the 4.3 US LTE image and it was actually the 4.3 ROW image. I didn't notice this until after flashing, and seeing the H+ icon, and noticing lack of ATT usage tracking app. Oops.
I don't see the 4.3 US LTE image on the site; I'm now downloading the 4.1 image, and will do OTA updates from there, checking as I go how which signal my radio is getting.
No Joy.
I flashed US LTE 4.1 image. AFter the flash, LTE Discovery still reports just HSPA+ signal from WCDMA towers. I then let it take the OTA for 4.4... the latest available for the US LTE tablet, and after it ran through its update process, I'm still on WCDMA.
Uggh. I doubt there's any WCDMA signal where I work so I may have killed my tablet, at least as far as using it at work is concerned.
I'm sure there IS a path back, I just can't imagine what it might be, at the moment. I'll start a new thread to be more specific to this current problem.

Thanks Son-j. It kind of freaks me out that just a week ago I found the thread that recommended those two changes in buildprop, but now I can't find it, and apparently neither can you! So maybe I'm not crazy, since it's more than just me having problems finding it.

Eventually found that thread with the buildprop changes, see here if interested or if you ever need to find it.
I just checked my Shield on T-Mobile. In the same area on LTE Discovery that yours says W-CDMA mine says the same thing (under Neighbor Cells). When you scroll to the bottom, what does it say for carrier?
Carrier: AT&T (310410)

Here are screen shots of my sim status (personal details redacted) and the LTE discovery window:
I am thinking that it is possible that W-CDMA doesn't mean what we think it means. It shows you connected to AT&T so you are not on someone elses network.

I talked to ATT. It's sort of their backup network, not available everywhere. My other devices definitely show LTE. Will post a screen so from my phone a bit later which shows that.

Here are some pictures taken from my phone, which is working properly. In settings, you can see the LTE network type and in the LTE Discovery app screen capture, all the LTE towers.
ATT maintains a "vestigial" WCDMA to allow some level of connectivity by devices that don't have GSM/LTE, but it's not everywhere and it's pretty slow.
The Shield used to show LTE in the Settings Cellular network type, as well as giving the LTE icon, when appropriate. Now it's just HSPA. Sigh.

My T-Mobile phone shows similar to your phone with LTE. T-Mobile must have a similar vestigial WCDMA that is showing up on my tablet. I still haven't found anyone that was able to get T-Mobile LTE working after it was only giving them 3G and HSPA. I have heard it either worked or it didn't.
