1700 and 2100 wcdma on N7100 intational

So I was playing around with my unlocked note nd I found a selection of bands nd I can select them but not sure yet if it does unable 1700 nd 2100 bands to work on wind mobile or tmobile any ideas ive the pictures
What code did you enter to find those options?
Note 1 had the same menu options.
It doesn't mean anything without actual support in the phone.
I assume, like the Note 1, if you turn those on your phone is going to reject your sim card.

Hi just peeked into this and was able to select 1700 band, go to comi bands and select 1700 wcdma and any other missing band and it will be selected. If it makes any difference i dont know since im in a good refarm area for tmobile.

By the sound of it our hardware just don't have the bands but yet we can select them kinda strange but if you could try using tmobile sim let use know what happens
I was able to do this also, with the leaked XXDLJ2 FW (4.1.2) - I tried with earlier FW before and couldn';t get into the menu - could be total noob error though...
Remove SIM card first.
Then power up Phone, dial #*197328640*
Select: DEBUG/PHONE CONTROL/NETWORK CONTROL/SELECT WCDMA BANDS
from there, it seems you can select ALL, or add the bands you want. (I'm on TMO USA so I selected 1700/1900/2100)
Now, what I don't know is...once you re-insert the SIM ( and you have to power cycle to do that) does the TMO SIM override the changes I just made? I have very weak 4G near my house so I cannot check if 4G is working or not.
CORRECTION: Forget what I said about removing SIM card !!! I was able to access the menu with the SIM inserted, and it looks like my settings are holding ( there's an asterisk next to the WCDMA bands I chose). This is promising!
I did this on a stock rom and after rebooting settings stay the same. Cant tell if itll make any difference since im at work and dont get good coverage. Will report as soon as i can and im on tmobile california
Sadly, it appears that any other setting than Automatic will disable WCDMA altogether - I sat in my car for 20 minutes right under a cell tower tryin to make it work, but was stuck on Edge...as soon as I selected AUTO, my phone jumped to H+ ...and it was on the 1900 Band since the 1700 band is automatically unchecked when switching to Auto. Oh well...gotta wait for the damn TMo refarm then.
The TMUS reframe is killin' me. Neither my house or work are in a reframed area. However, there are several points on my commute that are reframed, and I did have a chance to eat dinner in one. Holy moly is HSPA+ fast! EDGE is virtually useless with these devices.

you can select mulit bands that way you dont have to use auto as it does turn em off ,i used the last selection it lets you select what you want
Sorry to check in late but with these changes I notice that my signal sticks to 2g and barely wants to switch to H or H+. Maybe when Im off work Im gonna try to select all wcdma band and switch to wcdma only in network mode. when selecting network mode i notice it changes all the settings in the service menu.

that's what I've been doing - COMBI BANDS, and add GSM 850/900/1800/1900 and WCDMA 1700/1900/2100.
But it didn't work for me, phone remains stuck on EDGE -
I dont think this does much only put me in Edge mode or no data at all. Its weird that theres an option for it. So ya no luck here...

[Q] [N9002] Galaxy Note 3 Duos Enable LTE Band 4 from Service Menu, Does this work??

Hi All,
I stumbled across this as I am currently not in the US to test this out. Could someone see if this actually works? It supposedly enables the LTE band 4 on this phone even though specs say that there's not LTE on it. I was hoping it would be there as it has the same hardware as the N9005.
According to the Service Mode on the N9002, you can enable VZW LTE Band 4. I believe T-Mobile also uses this band for their LTE. I enabled it for me, but I am currently in an area that I can't test it. I posted screenshots of the Service Mode, and a video capture going into the menu.
How to enter service mode:
1. At phone dialer, dial *#0011#.
2. At the service mode, hit the menu key, and select back. It looks like it did nothing, but go to the next step.
3. Hit the menu key again and select "Key Input" and type "Q". It looks like it did nothing, but go to the next step.
4. Hit the menu key again and select "Key Input" and type "0000" (zeros).
5. Wait until you see "Main Menu"
6. Select [3] LTE
7. Select [2] LTE RF
8. Select [1] VZW LTE B4 on/off
9. Select B4 Enable(). It should now have an asterik in the parenthesis.
10. Reboot phone.
Here's a screen capture on how to enable it.

I tried this on the N9002; Dual Sim variant.
If you have a different version, this might be better for you as I didn't have a custom kernel for mine.
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
I just ran the process and my phone rebooted without problems (N9005). Now, I just have to get an LTE sim card for a network that runs on those bands (I'll try to do it on this weekend and confirm if it worked).

We have the same phone, sorry I didn't mention that. I'm running a custom rom, witch I guess is only an advantage... But you enabled lte band 4 and in Sweden my carrier has band 3. I checked the other "how to" but it seems a little bit complicated and I'm a little bit worried about messing things up.

It should be fine. I've done it a couple of times and it rebooted fine and connected to the area cell signals, just the area i'm currently in doesn't have any LTE.

I have a n9002, but i'm in Italy and VZW LTE Band 4 are not used here.

I tried here in mexico. Telcel ,Movistar, and Nextel both use band 4 for LTE. Did not connect, only H+, but also there is no menu option to switch to lte only wcdma and gsm.

I don't have a way to try it right now(my n9002 is at a repair shop atm), but would you mind trying this? the article says to modify the /data/property/ persist.radio.lteon file to "true" and “LTE/WCDMA/GSM (auto connect)” should show up as a selection of network preference. Can you let me know what your results are when you try it?
//smokeys.wordpress.com/2014/04/06/how-to-enable-lte4g-on-samsung-galaxy-note-3-sm-n9005/
Sorry for the long wait, wife had phone. The file was already set to true. No lte option in Network Mode menu.
Thanks for trying. I realized that my bootloader is locked so I can't flash a permissive kernel. I think that would've been able to do it I think... oh well
My SM-N9005 was crahed 4G/LTE when i test that... even if I disable, my 4G not working now
How I can deblock that ?

I try this and I still have only 3G/H+ on n9002.
Probably Samsung does not include LTE Modem

I did all your steps. But in RRC (Service mode, main page) i'm still see "RRC: IDLE, Band5" and i don't connect to band4. I checked and that band is activated.
Why?

[Q] Nexus 4 can't find AWS network

I Have a brand new SIM from WIND mobile in Ontario that came in another phone. I have this Nexus 4 kicking around so I popped in the WIND sim, but it does not connect. When I go to search for mobile networks in settings, it finds all the non AWS carriers (including the 'WIND away' network) but does not show Wind 3G (this is what the correct network lists as on my phone supplied by them). I have played around a bit in the *#*#4636#*#* menu, but nothing seems to make it work. Is the AWS band disabled in some Nexus 4s, and is there a way to enable it?
Welcome to XDA
Okay, first of all to avoid duplicate threads please use the search function of XDA to find your answer, or do a little Googling...
Anyways to answer you question, the AWS band of the Nexus 4 is disabled by Google to lower costs. That may sound crazy, but the story goes something like this:
If you didn't already know, The Nexus 4 is based off of the LG Optimus G, and has a lot of the same insides...
The same board was used for the nexus 4 and Optimus G, and on some of the G models they had LTE on band 4 and 17.
The nexus 4 never went through the FCC for LTE so Google disabled it because it wasn't worth the trouble of supporting 1 band.
Now, your answer: Depending on the Android Version, it maybe as simple as tinkering with the Info menu you were in. (4.2.1)
Newer versions were harder to enable LTE
You need to figure out what you need to do depending on the newer version.
You may need something as simple as an older radio
You might need to unlock your phone's boot loader, (which requires a factory reset), or maybe even have to flash a custom recovery (like CWM or TWRP) and custom rom.
It would really help I knew more info about the device likel what Android version,if its rooted, or has an unlocked bootloader,etc.
If you don't know what any of this means DON'T WORRY, there is an entire community of people willing to help
Sorry I should have gone into more detail. I have done the various tricks to try to enable LTE, but is that the same as enabling the AWS network? I was under the impression from the WIND folks that the Nexus4 worked for them stock.
As for the firmware version, I have tried on 4.2, 4.2.2, KitKat (4.4 I think?). I have tried after flashing the stock roms of each of these versions as well as after rooting. I have also tried flashing different radio versions to no success.
I should also mention that under the "4636" menus I have tried to click "select radio band" from the menu, but this just crashes the process and goes back to the first menu.
So does no LTE mean no AWS?
Hmmm...
First of all, NEVER click Select Radio Band, like you said, it crashes both the menu and resets your connection. Bug? Unfinished feature? No one knows.
You are supposed to click on GSM/LTE button instead of WCDMA preferred.
If that sticks then you might be done on (4.2.1)
If on higher version, then get the older .33 or .27 radio or a hybrid radio
AWS is the band the nexus 4 has unofficial support for, so its actually the opposite:
No AWS=No LTE
So try getting 4.2.1 via factory images and try getting that working okay (WCDMA→GSM/LTE)?
If not then tell me
How about 4.2 (JOP40C)? I have that currently but I can go back and get 4.2.1 if necessary.
And just to put the AWS/LTE bit to rest, can I have (on this or any other phone) AWS without LTE, or are they synonymous?
I am playing with it right now without the sim becaue it is busy in the other phone. When I switch to GSM/LTE AUTO, I find AT&T as well as the big three Canadian networks, but still don't see WIND. I did not see the AT&T on WCDMA, but its spotty near the border here anyways.

Sorry for the late reply but,
In 4.2 all you have to do is switch to GSM/LTE and switch to correct APN's in the phone settings
You can AWS on 3G as far as I know but it won't make a difference...
The only reason we are using AWS band for LTE is because its the only one the Nexus 4 can see.
As for the last paragraph what do you mean you cant see WIND? What do you mean by "seeing"?
Can you clarify?
Sent from my Nexus 4
Could you try this small app (should trigger the radio band select menu) to see what options do you have?
https://play.google.com/store/apps/details?id=de.mangelow.network
For the Wind Mobile AWS, you will need the WCDMA option. This is what Wind Mobile use, not LTE.
If you will be able to select the WCDMA option and still no Wind 3G/HSPA, then we will tinker with the APN settings.

By 'seeing' I mean when I go to the network selection / search function in settings. When I click to search for network providers, I do not see WIND3G as an option (or any WIND branded network). On the phone they provided me, when I search for networks I have several options that are labelled as WIND. If I recall correctly, I think I have about 12 choices between various providers, whereas with the Nexus 4 I just show three selections.
@DupleX01, Thanks. I will give that a shot when I get a few minutes to play with this at home. It has been a couple of weeks since I have worked with the Nexus.

It's a slow day at work, so I am back on this. I have tried setting the radio to WCDMA only, but this does not make a difference. The only network I can see with the SIM in is "WIND away", which I believe is Rogers. So I am on roaming. Should I flash a different radio to the phone? Anybody got suggestions on which radio is the best version for use on WIND?
With the SIM in, the APN settings are already correct for WIND, but I am not finding their network.
Also just for kicks I flashed kitkat (stock) again, including the radio that comes with the ZIP. No changes in network availability.. Gonna leave it on this for now unless someone suggests that it might be better to revert to 4.2.1 or another version.

Based on your findings, I would say everything is alright on hardware side (APN is good, radio ok for WCDMA). So, it could be a glitch with Wind micro sim card. Still bonded to the previous phone IMEI what not. Make sure you now the serial of the micro sim, your imei of the new phone and give them (Wind Mobile tech support) a call.

LG V20 ATT in Europe Bands

Hi, Im newbie here, and eng is foreign language for me. Sorry for mistakes.
I have an LG V20 H910. Unlocked. No root. And he works only with 2g (edge). 3g, 4g isn't working. But in specs, he have bands what I need.
https://www.frequencycheck.com/models/vVVRj/lg-h910-v20-lte-a-h915
My operator bands:
2g: 900MHz, 1800MHz
3g: 2100MHz
4g: Band3-1800MHz, Band7-2600MHz
I've tryed https://forum.xda-developers.com/v20/help/t-mobile-v20-band-12-solved-t3508910
But in my case *#546368#*918# menu is much different, there is no options like "choose bands" or smth.
Any possibilities do turn on at least 3g band?
P.S. Once, when I'm switching sims, the phone dind't find network much time. Then I've installed V10 hidden menu https://play.google.com/store/apps/details?id=you.love.v10.hidden.settings&hl=ru and simple change option "Mobile network" (GSM/WCDMA/LTE and CGS/WCDMA). I have tap on this two times on final chose GSM/WCDMA/LTE. On the top appeared 4g icon. The speed was about 4 mb/s. But it was one time, when reboot the phone all dissapears and I cant repeat my experience again.
try adding APN manually.

I did it. + I show this phone to my carrier experts. They sad, that they can't help, couse ATT somehow locked bands. Is it possible?
P.S. Once again: phone is unlocked and work in 2g.
I think if this was on V20 it may helps me https://forum.xda-developers.com/lg-g3/general/request-3g-2g-lte-d850-t3300908 . But it is G3.

It might be locked in the ROM. If you are up to rooting, you can put a custom ROM on it and there is a high chance it would work.
Same situation here. Tried all custom roms i could find with the same result: kernel crash at boot menu

How to force VZW E4 (post-unlock) to use GSM/WCDMA/TD

Hello,
I am trying to check how i can have the phone force all bands and not just LTE only. My phone after i unlocked it works great on t-mobile, However, i have to always go back
and change the radio to TDSCDMA/GSM/WCDMA etc so i can get LTE and voice. It defaults to LTE only. Anyone know how to clear this or force on one band ?
Thanks
