How to force LTE/GSM/CDMA auto (PRL) or any other Preferred Network Type.

Hello, I have no problem receiving an LTE signal on BCE (Canada) through the Phone Info Menu. I can select any of the preferred network types including LTE, LTE/GSM, CDMA, LTE/GSM/CDMA but it won't stay. Every day I have to go back into the menu and it reverts back to the first selection "WCDMA".
Does anyone know how to force this so it stays on LTE/GSM/CDMA. So it will stay on the LTE-enabled network unless there is a loss of signal and it reverts back to HSPA? It does this automatically when "LTE/GSM/CDMA is selected, but again reverts to CDMA within a day usually.
I did some searches here, but 99% of what comes up is just people asking how to enable LTE or if their network gets it?
Any ideas? Maybe some sort of macro thing.
Regards.

Add this line in build prob
telephony.lteOnGsmDevice=1
Save
Reboot
Now in settings/more/mobile networks u will have an option to choose and it will stick. U have to add the line every time u flash ROMs.
But I keep iron WC DMA/gsm for better battery speed is OK on h+

Thanks for the helpful reply man. I haven't edited a build.prop yet, so Ill have to check it out.

Alright thats all done now, works like a charm. Like that I have the option now either way. I typically stick to WCDMA/GSM when on the road or at work where LTE is spotty, but on days off for around town I would rather just be on LTE as I usually just looking up something quick when Im shopping or something.
Thanks again.

Nice
I keep it at LTE, it does have less bars but quality is same for me, speeds are amazing. Also 4G is only data, not voice, so when u have an active call it will change to 3G.(but that's not the phone it's the network)
don't forget to do it again if you flash new ROM, also Tethering WiFi won;t work, there is a fix but it's complected for me, so I just go to W/G if I need to share connection.

So, my Nexus 4 shipped today, and it'll be in my grubby little hands by tomorrow evening. I, unfortunately, can't activate it until March, as I have to wait for my Verizon contract to end, but I keep seeing this LTE stuff, with no real explanation. I do know that the Nexus 4 has an inactive LTE radio in it, but what's the use of activating it, if T-Mobile doesn't have LTE? Is this only for the AT&T users?

There are other threads dealing with who can access LTE in the USA. I am in Canada and on Bell.

I'm in Canada, using Fido. I activate the LTE on my Nexus 4. It works fine, but I'm not able to share internet with wifi hotspot.
I have Android 4.2.1 (latest OTA from Google).
There is a bug with this version or it's only because I activate LTE manually ?

As per the previous comment:

what is the fix to get hotspot internet sharing with the Nexus 4 ? Do i have to had a APn for 3G and swith that it to share my connection ?
I'm with the original firmware. Android 4.2.1

process com.android,phone hase stopped working
i recently got a rom from revolt on my n4 and i switched cdma to lte gsm wcdma auto
i also went into build.prop and wrote down telephony.lteOnGsmDevice=1. i went and to setting, more, mobile networks chose the correct setting. so now i got 4G. great i can make calls. GREAT. but i cannot receive calls...
need help with this. im really choked about this ROM

Even if I select "LTE/CDMA" in the Mobile network settings menu. The settings page keeps displaying "CDMA preferred".
Does this mean it didn't work? In quick settings, I see my mobile data connection as 3G Bell.
LTE only seems to work when using the *#*#4636*#*# trick in the Phone app.

Would you have by any chance the line for the built.prop to stick the setting to GSM Auto (PRL)?
TIA!

Thanks, but LTE doesn't work in my country, its always stick on lte/gsm/wcdma but it doesnt detect my gsm so i have to manually set it on GSM only but wont stick here every time i restart my phone i have manually set it on GSM only otherwise it wont detect my network
Any advice ?

How can I make "WCDMA Only" the default selection?
Where I Iive there is no LTE and the coverage of the service is quite poor, so the phone keeps jumping between E and 3G/H. I have to manually go into the phone app and select "WCDMA Only" is there a build prop tweak to make the "WCDMA Only" the default option instead of "WCDMA Preferred"?
Thank you.

So is there a way to get the nexus 4 to work on Verizon ??

Aah Crap ! Well thanks man saved me from buying on guess i will have to stick with my rezound for now then

fixed it
For everyone still searching for a solution to this problem, this worked for me. Go to phone information and turn your radio off. Then switch to LTE/GSM/CDMA then power down, DO NOT TURN YOUR RADIO BACK ON. Now remove your Sim card, put it back in, reboot and you should be good to go. DO NOT HGO BACK INTO PHONE INFORMATION OR ELSE IT WILL NOT STAY
If it still isn't connecting try fiddling around with your APN settings.

You may not need to do anything. You need to enable or have a ROM which has enabled hidden menus, and then you can check whether you are on xLTE. If you go to the dialer and dial *#0011# and hit send, you will see LTE CONN BAND and it will say "13" or "4". If it says 4 then you are on xLTE.
For me it rarely works inside buildings, but I notice I'm on it a lot when I am outside or in the car. You can check if it is enabled by dialing *#27663368378# and going to UE SETTING > SETTING > SYSTEM > NEXT PAGE > VZW B4 LTE ON/OFF > B4 Enable should have a star. If it does not, enable it. DO NOT change anything else or your phone will probably quit working right! Exit and Reboot phone and you're good to go.
There is a thread around here somewhere about enabling the hidden menus.

I'm on Baja rom and unfortunately when I dial these commands in my dialer nothing happens

Check this and this thread out for any help, but basically what you need to do is edit the file /efs/carrier/HiddenMenu with Root Explorer or ES File Explorer and change it from OFF to ON (uppercase required).

B4
I went into the hidden menu and manually switched on B4 and made sure it had the asterisk next to, rebooted and then dialed *#0011# to check which band I was on and it always says I'm still on 13. Am I doing something wrong because it doesn't seem to stick on B4?

No, I don't get B4 very often still and I live in the Metro Detroit Area and in a very densely populated area. Just check it when you are in different places and you may notice it has switched. At my old office I always had B4, and we moved 2 minutes down the street and now I don't anymore. I rarely get it when I'm inside houses or buildings. It's too bad there is no way to tell which towers have it enabled except just driving around and looking for it...

Band 4 is not good for getting inside a building. It's at 2,100 MHz whereas Band 13 is in the 700 MHz range and far superior for use inside a building.
You shouldn't care what band it's on as much as how well whatever band you're on you get reasonable speed and battery life.

Just being on B4 does not necessarily mean you are taking advantage of XLTE. XLTE refers rather to the amount of bandwidth you are getting, other than that it just so happens to be on LTE band 4. In order to confirm that you are taking advantage of XLTE, after you make sure that B4 is on (with the asterisk next to it in the hidden menu settings), you also have to dial *#0011# then read the line where it says BW (either 1st or 2nd line, depending on your modem version), if BW (bandwidth) is 10mhz, you are still on regular LTE (regardless of B13 or B4), if you are on B4 AND BW is 20mhz, then you are on XLTE, meaning you have double the bandwidth of regular LTE. So far, I have NOT seen my bandwith change to 20mhz even though I am in an XLTE area and often on B4. In fact, when the phone is on B4 still with the 10mhz BW, the dl and ul speeds really suck, and connection is extremely erratic, and it just plain sucks, that's why Sprint and T-mobile's connections suck so much too, because they are on the higher frequencies. Unless you are getting the 20mhz BW on B4, for comparison B13 is far superior in signal and connection quality, and I always get much better connection speeds on B13, so don't get too excited yet unless you get the larger bandwidth.

[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 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 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?

How To: Selecting/Deselecting network bands

First want to put it out there that you do this at your own risk
I love that T-mobile has Band 12 LTE coverage but for me the data speeds on Band 12 are horrifically slow, so I prefer my phone to be on Band 4 LTE (at least while at work).
I used to do this change all the time on my S6/Edge and the steps are vary similar to do them on the S7(slightly more involved).
To start with, if you mess with bands, it can(and probably will) affect some sort of your service
So to change network bands you have to enter the service menu. To do this, go to the phone dialer and enter
*#2263#
Once here you will see a screen saying ServiceMode followed by various options
To turn off Band 12 choose LTE Band Preference (#4 on the list).
Then hit next page until you see Band 12 and deselect it (this will remove the * from next to it).
Once that is done, in the top right you'll see where it says "More" select this and choose "Back" - do this until you get back to the main page
Now back at the "Main Menu" choose "Apply Band Configuration" (option 7) and you're done.
Once you exit the menu(by hitting either home or the back phone key) you'll lose signal for a second while the phone switches the bands around.
To revert back to normal, enter service menue *#2263#, choose "Select All Bands"(Option6) and then Choose "Apply Band Configuration" and you're back to normal
Hope this helps someone
EDITed the info above so that you can turn off just Band 12 and keep calling features

Updated the instructions, figured out how to make the phone stick to Band 4 and still retain ability to make/receive calls

Oh Ya band 12 is terribly slow. At least when compared to band 4. Band 4 is wideband at 20x20 20mhz bandwidth while band 12 is 5mhz bandwidth. It's just barely enough.

I was wondering why my speeds suck since I've upgraded to a new phone guessing this is why

Do you have any approximations of the speed difference between the bands, like with speedtest or something?

I didn't notice any difference in speed with my tests was really hoping for better. I'm only getting about 15-20mbps now I was getting between 60-80 about 3 months ago

I'll get some later tonight - something is going on with LTE around my work and Band 4 and Band 12 are both acting up

Essential Phone Service Menu

On my old Samsung phone I could enter service menu and switch bands. I have tried to enter service menu on the Essential using *+#000000#, but I get "Connection problem or invalid MMI code". What am I missing?
Does anyone know how to switch bands on this phone, and make it stick? I'm tired of being assigned a crappy band with low signal at inappropriate times.

Yes, I have done that one. It is not the true service menu, but the test screen, where you can choose between CDMA, LTE, UMTS, etc. but that's not quite what I'm looking for. It won't stop the phone switching to a low performing frequency channel. I want to be able to switch to say band 4 or 5 or 66 and have the switch stick, disabling band 17 and 2. But thanks for the reply. The original *+#000000#, is close, but I'm missing something. Still looking.
