Hello! I do not want to use GSM networks. I found "WCDMA only" in the phone settings, but I want accept LTE networks too. Who know how can I do this? My phone is rooted and have a custom recovery, firmware V20h. Thanks!

Hi,
I just bought a Videotron locked SGH-M919V and purchased the unlock codes.
I am with Rogers, and since the unlock this phone works well for voice, but I can not get data to go faster than 3G.
In a place where i used to get 25+ mbps download with LTE I cant get more than 3.7 mbps.
When I look at the APNs, I have LTE tethering and Rogers LTE and Rogers LTE is selected.
In network mode I can only choose:
GSM/WCDMA
GSM only
WCDMA only
How can I get LTE speeds?
Thanks
Had the same issue on the BELL LTE network.
While searching on the web today, I found out two answers to your querry :
1 - Installing a little .apk application named "phone info" not available on the google store witch allow you to kinda force the usage of certain band (including LTE) on your SGH-M919V! See the attachement for the .apk application.
Once the application is installed on your SGH-M919V, open it
Select the first option (mine's in french, but it should be similar to Device Informations or Pheripherical Informations).
Scrool down to where you can choose the network bands or protocols from the menu.
On the Bell Network, "WCDMA prefered" was the default option, and changing it to "LTE/GSM auto (PRL) maked the phone switch between 3g and LTE speeds when available.
2 - Flashing the SGH-919's (non-v) modem.bin with odin. I tried this method, but it didn't worked as expected. The flashing wouldn't work as installed so I started to look for other answers. If someone found answers for this method, a tutorial would be greatly appreciated! (I followed theses instructione but it didnt worked for me :
I didn't wrote theses instructions, they are freely accessible on http://forum.xda-developers.com/showthread.php?t=2266101
1) Download the T-Mobile firmware from http://www.sammobile.com/firmwares/1/?model=SGH-M919&pcode=0#firmware
2) Find the file "modem.bin" and move it to another folder. This file should be about 50MB.
3) Put phone in download mode and plug in USB.
4) Start Odin software.
5) Select "phone" and select the "modem.bin" file.6) Only thing checked should be "Auto Reboot"
7) Hit Start
8) Let it reboot and after that you should be able to connect the LTE network.
The first method is the one that worked for me. Feel free to post any questions if unclear, i'll be glad to answer!

Might be Rogers oversaturated LTE Network.
The solution I found is this
For M919V flash the entire original stock rom of I337M from rogers, bell, or telus (3x) and reboot after each flash and then wipe cache and factory reset (with stock recovery). Your phone becomes I337M even on bootloader. Now you have LTE. To get AWS band, look for a thread that says how to enable AWS for I337/I337M . And now you have LTE + AWS
I recommand flashing Telus I337M 4.2.2 rom (it only has one telus bloated app) or the Bell one (4 bell apps). Rogers is the worse rom to flash lol
I've experimented and tested it, thus it definitely works!
That solution seems to work for M919V models only.
I'm using the E975 and I've unlocked the bootloader, installed CM11 on it.
However I realised that the ROM did not detect any signals. I couldn't make calls or SMS.
I had to manually go to the network settings and find the carrier (Singtel) to register everytime I start the phone.
I then flashed savvy 4 ROM to see if the network was any better. It was, but then I was limited to GSM only. I couldn't get 3G or 4G.
Before I unlocked the bootloader, I had 3G and 4G signals.
Then I decided to KDZ back to stock ROM. I had network but only limited to GSM.
I realised my phone could only detect GSM signals from Singtel, M1 and Starhub. I couldn't see 3G or 4G.
I don't know what to do now. I need help. Must I flash any basebands or modems or anything? Thanks
are stock recovery and boot files same for all regional versions of ruu. Please ans me. I am having problem afterrevert back to ruu. 3G net work stop working and I can't use 3g internet. Please help, if anyone knows about it.

Are you able to use 2G atleast? Did you check the APN settings for your carrier?

Yes, I can use 2G. I checked apn settings. When I select WCDMA only, network just goes off. but when GSM or WCDMA Preffered is selected, then only 2G starts.
Hi All,
I am a G3 User from Singapore and my model is the D855. I've noticed that after rooting and changing to Custom ROMs I've only been able to get H+ and never LTE. Before when I just got my phone it was able to receive LTE.
What is the problem here? Do I have to flash some modem update or something? I'm not clear in this area so any help is appreciated!
I'm very sorry if I'm not doing something or doing something really stupid.
Thanks guys!
EDIT: By the way, I've selected LTE under "Preferred Network Type" and I still get H+.
Check the APN settings and make sure they're correct for your carrier. Custom ROMs don't always have the APN settings configured correctly.
From my research on the subject, it seems that Google has seen fit to remove access to the hidden menu that allowed us to switch bands? I've been looking for a way to change it or access the menu for a month now, and come up with nothing. I live in India, and my provider is Airtel, which uses the 1800 and 2300 (maybe 2100 as well?) bands, both of which my D855 support. My mother's Xperia Z gets LTE just fine. I've switched the network to 'LTE only' in the Testing menu, but that just cuts off my connection to the network. It's usually set on the default, which is LTE/GSM auto (PRL), and which HSPAP works on perfectly fine. I don't know if it works on the stock ROM, because I switched ROMs before I got the connection. Currently running the crDroid 05.02.16 build. It's not worth switching back to stock just for LTE, but it is annoying to not get it when I should be able to.
So basically, I'm looking for answers to 2 questions:
1. How do I switch bands?
2. Will switching back to stock, switching bands, and then going back to crDroid work? Would the band change persist across flashes? I doubt it, but if that were possible, I'd be willing to do that.

Did you update the apn for your carrier when you went to a custom rom? if not do it first and check if it solve the problem.
if you did uptade the apn but it still not working try this: go in phone dialer and type *#*#4636#*#* ---> phone information scroll down you are going to see "Set preferred network type: (select the one you want).

Already set APN, and preferred network type is on LTE/GSM (PRL). My mother's Xperia Z has the same settings, and gets LTE just fine. Switching it to 'LTE only' makes me lose signal altogether.

the compatible band for D855 are LTE 700 / 800 / 900 / 1800 / 2100 / 2300 / 2600 airtel in indian uses 1800/2300 bands. Thus your phone is compatible. Thus I assume the problem come from your phone and most probably you might want to flash the Modem ....
What i suggest you is to backup everything and try this rom for d855 http://forum.xda-developers.com/lg-g3/development/stock-d855-30b-images-kdz-flashables-t3282012
the modem is already in it. If it work your modem will already be flashed for marshmallow as a result switching back to your ROM will not affect the Lte compatibility.

Thanks! I'll try that when I have some time, but for now, I can't have my phone out of commission. I do have a TWRP of stock Lollipop; would restoring that be enough? That would be much faster, I could get that done in less than an hour. Or is KDZ flashing MM the only option?

Restored stock LP from TWRP backup, and tried changing the band. Tried bands 3, 5, and 40, but choosing any of them only results in the phone searching for a network and not finding any. When I set the RAT to GSM/WCDMA/LTE auto, it reconnects and I get HSPA+. Switched back to crDroid soon after.
I'll try flashing the modem from the KDZ soon, and then the whole thing if that doesn't work.

did it work? was it a modem problem ?
Flashed the hybrid modem yesterday; nothing appears to have changed. [emoji29]
