Get internet sharing and MMS working on unlocked Rogers (and AT&T?)

I finally got my internet sharing and MMS working on my unlocked Rogers Lumia 900 running on Bell. Earlier this week, I came across this page. http://forums.wpcentral.com/lumia-900/197920.htm. If you follow his instructions (minus the unplugging the cable during the rom flashing), you should have working internet sharing and MMS without having to input any APN settings. The first time I started it with the TelCel rom, I still had to input my APN to get data to work. Then I performed a hard reset by holding volume down, power, and camera buttons. After that, it picked up the correct settings from the sim card and everything works as it's supposed to. The only downside to some people is that now instead of showing "LTE" in the status bar, it shows "4G" and instead of "4G" when you are on the HSPA network, it shows an "H". I think this is a truer representation of the network you are on anyways since HSPA isn't a true 4G network like the American companies would have us believe.
Please note that if you are going to do this, you will lose any unsynced data on your phone and will also have to reinstall all your apps so backup what you need to.

Seems interesting. I will wait for the 7.8 version to come out. I wouldn't want my phone to be stuck at 7.5 for some reason after trying this.

If for some reason it doesn't update to 7.8, you could always just flash the stock Rogers rom back to your phone and then get 7.8.

Have no problem with 4G, sharing and MMS on original AT&T firmware (using my lum with Europe operators).

Could it be a SIM card flag that prevents the sharing, the euro ops SIMS dont have it
Could it be a SIM card flag that prevents the sharing, the euro ops SIMS dont have it but the NA ops do?

May be, may be... But I had problem too with this features, when it worked on a 1st firmware (flashed by AT&T, not by me). Then I decided to flash it on my own via Care Suite (had flashed the earliest firmware, then updated via Zune). Now it works without any problems. After flashing try to not use the Nokia's Network Setup. If sharing would be OK, you could install NNS on your choice

It works for me after doing a hard reset with t) mobile, if I run NetworkSetup then it stops working. If I insert my att sim then it also stops working.

One more datapoint...
Recently unlocked, using Taiwan Cellular unable to tether.
Before installing Network Setup receive message: no data connection found...
After installing Network Setup, "to enable tethering on this device, go to att.com...".
Same SIM card in HD7 allows internet sharing... no problem. So it's not the SIM.
On HD7, data connection shows "H" but on Lum900 showing "4G"... (not a problem, just observation)
Have hard reset with Taiwan SIM, no joy. Reflashed using Nokia Care Suite... same results.
1. It's clear, stay away from Network Settings app. Even overriding APN settings results in same bogus ATT message.
Any point in flashing a pre-8779 rom? One of the TelCel MX or Claro LTE roms?
To flash another RM808 carrier's rom on top of an ATT RM808 device, is it a straight flash with NCS or need to rename files?

No LTE when using 919V with Rogers

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.

Electrify M (XT901) possible radio capabilities

Hey whats up xda. As some of you know the Electrify M as the sister phone to the Razr M. Ive used this phone for the past couple of months on PagePlus and just figured I'd start messing around with it to possibly be able to use it on tmobile/att. In the last 2 days Ive made some progress using a tmobile sim card. It picked up signal but wasn't successful with calls, text or data. I didnt have enough time to fully test it since its my brothers sim but at the moment have a simple mobile sim for testing which for a briefly picked up signal when attempting to register on the network and display (network with limited service found) and not finish afterwards saying something similar to (service not available please try again later). Well now when I try to search for the network on simple mobile card attempts are unsuccessful and displaying (network unavailable). It only displays the phone number and voicemail icon at the moment. I'm currently trying to detect network on simple mobile again and go from there. T-mobile sim belongs to my brother so I'll prob go pickup a prepaid sim soon to test. It still displays signal on lte13/lte14 when tmobile sim inserted but still no signal the active simple mobile micro-sim which I read people have had trouble registering on the network sometimes. If I get anywhere Ill post it in development until then I have to get my post count up to do so.

What did you do to get it to pick up a signal at all?
I've done the 8322 NV edit and tried both GSM/WCDMA and Global modes by going into *#*#4636#*#*. Phone is stuck on "Searching for Service". Even tried a few build.prop edits and using build.prop from my RAZR M. No luck there either. I've tried flashing XT907 modem, also erased modemst1 and modemst2. I also tried with and without flashing XT907's fsg. I don't know what fsg is, but the FXZ always flashes modem, fsg, then erases modemst1 and modemst2. No luck there either. Can't even turn on the radio with the modem FW from XT907.
The fact you managed to get it to show a signal bar at all is further than I got.

fastboot flash modem NON-HLOS.bin
I also did:
fastboot erase modemst1
fastboot erase modemst2
Because that's what the fxz does.
Didn't work for me though. No signal, can't do *#*#4636#*#*, can't get into Status in About Phone, can't get into Mobile networks in Wireless & networks, Baseband version says UNKNOWN. Maybe I got a bad download? It did seem unusually fast. My MD5 sum is C3F9B3BAD2D5454C4E6D6F7803136567.
UPDATE: Downloaded official Aussie FXZ and flashed modem_signed. Same thing. Either there's more to it, or guy that suggested it is trolling.

I found it in an old tmobile hack thread I think.

How to switch LTE bands on MM custom ROMs?

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.
Sent from my LG-D855 using Tapatalk

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?
Sent from my LG-D855 using Tapatalk

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.

I need help on samsung note 4 N910v

My friend brought an original refurbish Samsung N910v android version 5.01 which was working with GSM 2G if not 3G until when I tried to update to new version android v6.0.1. In the menu>setting>about when I checked first before anything it showed me N910 F v5.01 but in boot mode Odin it was N910v.The problem started when I just typed *#9090# the phone immediately started reboot loop. I have managed to unlock the boot loader and root the phone installed custom rom version 6.0.1 by Paul Pizz rom VRU2CPJ2.r-1 but still can not have 2G or 3G GSM network. Please help to revive the phone again whether it meant to go back to 5.0.1 that would work with gsm cause am full stack now.

Have you checked to ensure you have the APN information in place? I have a Galaxy Note 4 N910V now (just got it a few days ago) and when I put my T-Mobile SIM in it from the very first time I have to manually put in the APN data - on custom ROMs it's usually picked up and there automagically but not always so, my suggestion is that you check to make sure your APN information is currently there as it should be.
Settings - More - Cellular networks - Access Point Names - make sure the one you need to be using is selected and if it's not then you'll have to put that info in manually and save it.
As for the actual model number, take the battery out and see what the model number is on the sticker in the battery compartment area - if the sticker isn't there then it could be a device that someone has done some experimenting with because that info can be changed. The sticker should be there, of course, but sometimes people take 'em out when they're mucking around with stuff, who knows.

Initially the phone is from Verizon but was working on 2G ,3G GSM network with N910F firmware version 5.0.1.it was working on airtel network until when I wanted to update. May I have the Apn settings,please

The APN will be your network. Are trying to use Verizon? If so, you should have a spot to tic the VZWINTERNET. If not, then you have a sim card issue.

ziggy the how do i sort out the sim card issue ,Since phone says this sim card is not from verizon

Is the sim from verizon? If you have a good account go to a corporate store and have them give you a new one. It's free.
Also, what are your APN settings and I will compare to mine. Everything works on mine.

the fone I have came from china ,am in Africa and remember I told you it was working woth N910f firmware version 5.0.1.All am asking is there anyway I could make this fone work again on Gsm network, cause all it says after re flash is the card is not from verizon

I now rooted this n910v android version 5.1.1 still no network, am in Africa where there is 2G&3G GSM network, how would I make this fone to work again with the gsm network now that I rooted. On the network bar I get a circle with a cross ,how to make this work

- N910VVRU2CPJ2_FullFirmware_NoAboot<--- Full Framework with no aboot so you will not re-lock bootloader, but will unroot and restore back to 100% stock. once your on the full stock check if your connections are working fine, if they are then install custom rom, otherwise change the sim card

go in settings, connections and select network mode to global, should be fine
