I've lost 4G on my N7105

Cut a long story short, I got my new N7105 yesterday and rooted it straight away,
I then made a BIG mistake and installed a N7100 rom onto it which messed it all up and lost all reception on my phone.
couldnt make calls ect.
someone on here sent me a link to download the stock N7105 rom and it worked. i can now make calls ect.
BUT... since this has happened, i have not been on 4G once.
i've tried everything, been inside and outside, trying to get 4G.
before this all happened, i had 4G everytime i turned my wireless off.
I'm based in london UK, so there is really good 4G here.
anyone know the reason why i have lost my 4G?
do i need to download something to get it back?

Go to Settings > (Under Wireless and Networks) More Settings > Mobile Networks
and check what network mode it is set at.
It should be like the following:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}

yeah thats exactly how it is.
like i said, i've got reception, i get 3G, but just dont ever pick up 4G.
its as if i've done something wrong when installing the wrong rom and its messed up my 4G.

I presume your on EE?
You might want to check what network operator your phone is set to (it's right underneath Network mode)

Yes Mr.Larner is on EE T.Mobile

Also try switching between network modes (so switch to WCDMA and switch back to LTE) this used to happen to me until EE built more transmitter masts.

The only other thing that I can think of is that his APN might be incorrect. Can you link me to the stock ROM he flashed?

Hmmm, everything seems to be running perfectly, the only thing I suspect now is that your APN's maybe incorrect. I'm currently on the WanamLite ROM and I get 4G perfectly.

that is what even i am suspecting , had him call his service provider to check with that they ran couple of tests and said everything is fine
are you on same carrier if yes share your Settings ?

Yes I am on the same carrier. My settings are:
I just checked the EE forums and this is what the APN should look like:
Name = Internet
APN = everywhere (case sensitive)
Proxy = Leave Blank
Port = Leave Blank
Username = eesecure
Password = secure
Server = Leave Blank
MMSC = Leave Blank
MMS proxy = Leave Blank
MMS port = Leave Blank
MCC = 234
MNC = 30
Authentication type = PAP
APN type = default
APN protocol = IPv4
Bearer = Unspecified

Finally after a lot of juggling around flashed WanamLite rom with custom kernel now Mr Larner has his smooth 4g back.

N910V No signal in Argentina

Hello everyone,
I bought a Unlocked Note 4 from Verizon in USA. In Argentina I don't have signal. We use GSM so it should work right. I know this device has not root access. I just want to make some calls or messages.
It doesn't let me search network manually. It throws an error "error searching networks"
Android Version: 4.4.4
Network Mode: Global/GSM
Somebody could help me on this.
Thanks in advance.

I am in Europe past month, leaving to us in few days and was using my note4 in GSM mode all the time and switching between carriers on a prepaid sim. I would do factory reset or maybe get a new sim.
My prepaid sim allows roaming on all carriers.

I already flash the mobile with Odin thinking that the Android version might be the problem. It still not getting signal. I'll try with another SIM card.
Did you use others GSM carriers instead of T-Mobile?

I tried with many SIMs, I flashed the device three times and I still having. So maybe there is a another issue. Please someone can help me. How is the Micro SIM should I use?

Which carrier are you using this on? Verizon has always used CDMA for 3G, not GSM. The Verizon Note 4 (SM-N910V) does seem to have limited GSM support, but it might not work on every GSM carrier.
This website seems to be pretty accurate: http://www.willmyphonework.net/

Acording to that page my phone should work perfectly
with 2G, 3G, 4G LTE.
I'm using:
Brand: Samsung
Model: SM-N910V
Country:Argentina
Carrier:Claro Argentina
I don't know what is the problem.:crying:

You may need to add new APN settings before it will work.
On mine, the option to add a new APN is disabled, but I'm actually using mine on Verizon with a Verizon SIM card, so I'd have no reason to edit the APN settings manually. Are you able to edit yours?

I already set the APN and nothing happens. I'm not sure APN could be the problem. Should be something else.

If the APN settings aren't correct, it could absolutely be the problem. It's worth double checking.

I have an Oneplus One with the same APN and works perfectly. That's why I think the APNs are not causing the problems of signal. I still having no signal. I cant make neither a call nor send a message.

Hmm sorry bro not sure what is going on.. last thing I could suggest if you have some money to spare try any other sim card from different provider or ask a friend to swap it for a minute or two,anything to test that it's not your carrier somehow not wanting to work with VZW N4.

Hey I read something couple days ago and forgot to get back at you.. I read somewhere if you block activation agent it should work some people on T-Mobile USA had the same issue. Use debloater to block activation agent on boot. They said this could be because the note could never been activated on Verizon even for 30 seconds and this is why it might be happening.
So block activation agent,and setup wizard so it's blocked on EACH BOOT.
Let me know

Lte on unlocked sprint s6 edge+ on t-mobile

Does anyone know if I can get lte working or is it possible to do

Probably not

Unfortunately no, it's not possible.

Why would it not be possible? It does support some of t mobile bands.

Lte band is different on tmobile gsm than on a sprint phones

I Am in same situation. It does not make sense if i go to ##data# i see bands 2,4,12 all LTE in priority list. It is there. How can we make it work?

Mine works on LTE, but signal is very unstable. Voicemail wont work unless switch back to 3G.

Just an update, I unlocked my phone. Connects to B2, B4, B12 no problem.

That's t mobile fastest lte. It will default to that unless you go out of an area that doesn't have aws. Then it should pickup B2 and B12 when available.

That's proof. How you get that to connect. I'm on automatic and get only 3g and the APN setting gets blocked. If I go to setting through root and change to LTE/gsm auto prl. I get only 3g. The phone sees the same LTE band your on but it won't connect. Only time it did was when I was using activate phone but it would not show accurate signal meter and then reverted back to 3g when it failed to activate

Used my msl to get into data and added tmobile apn. Left it on automatic and it connects perfect. Only thing I noticed is when using the apn fast.t-mobile.com, is you have to put it in like this. fast.tmobile.com. works fine.
Sent from my SM-G928P using Tapatalk

When I go into ##data# with edit using msl I still can't add or edit APN. It's working right now. But it's on LTE/GSM auto prl in device I go using advanced signal status app, which shows up as LTE GSM UMTS In mobile networks>network mode Only thing is the signal meter is not reading accurate and I have to make a call every few hours to get LTE to connect again. Going to try automatic again. I upgraded to latest update yesterday

I'll have to check again. I'll let you know in the morning

It works on tmobile
If you can get into GCF SETTING CHANGE NETWORK BANDS TO GSM/WCDMA/LTE. ONCE THAT'S DONE RESTART PHONE AND DIAL ##DATA# HIT EDIT ENTER YOUR MSL CODE.. NEXT HIT LTE THEN HIT LTE ROAMING MAKE SURE IT'S ENABLED.. PRESS BACK ON YOUR PHONE TO SAVE THE SETTINGS... NOW THE LAST THING YOU NEED TO DO IS MAKE SURE IN YOUR T-MOBILE APN SETTINGS BEARER IS SET TO LTE ONLY.. SAVE THE APN SETTINGS AND REBOOT PHONE AND BOOM YOU HAVE YOUR SPRINT UNLOCK EDGE PLUS WORKING ON T-MOBILE LTE.. RECEIVING AND SENDING MMS WON'T WORK UNTIL YOU UNDO ALL SETTINGS AND PUT BACK THE PHONE TO WORK ON 3G.

Verizon and the OnePlus 3?

Howdy!
So I've read that the OnePlus 3 is not compatible with Verizon, but if you look at the bands it's only missing Band 13. Wouldn't the others still work?
Thanks!

I will report on July 1 when my opo arrives.
Sent from my Shield Tablet using XDA-Developers mobile app

Verizon's primary band is Band 13 (700c) according to this website below.
http://www.phonearena.com/news/Chea...on-T-Mobile-and-Sprint-use-in-the-USA_id77933

Maybe the band will become editable by a rom. But who knows

700mhz B13 is not really a "primary" band it just happens to be what Verizon first launched.
I highly doubt that we will see 700 B13 on the OPO3. Vzw is rumored to be rolling out B2 1900 but I'm not sure if it's officially launched in any markets. There is also the fact that vzw uses CDMA BC0 800mhz, which if I read the specs correctly is supported by the OPO3.
All this being said I doubt the OPO3 will work fully supported by vzw.
Of course there are some brilliant people in the xda community who can probably shed some more light on the subject.

It will work with Verizon 3G I saw in a review video. Not LTE tho.
Sent from my VK815 using XDA-Developers mobile app

It has LTE bands 2 and 4, thus if VZW has LTE bands 2/4 in your area then it should work. I'm having issues getting the LG-H830 working, but it doesn't have CDMA. It connects to band4 in my area but no icon, since I believe it needs CDMA for auth.
I haven't tried this yet but you may be able to add band 13
http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059

Do you think a call to VZW customer care would allow one to know what bands are in an area? You'd obviously need to get an upper level service tech on the line...but could they tell you?

I would say waste of time based on my experiencettalking to them. Better off using apps to figure it out. If you don't have Verizon, just visit the store nearest to you and install LTE Discovery on a display phone.

Why would it not work on LTE? It supports bands 2 and 4. If your area is VZW band 13 only then yeah it won't get 4g signal.
Sent from my rooted and BL unlocked LG-H830 using XDA-Developers app

Surprisingly Skizzy034 is correct, 3G (eHRPD) works. I had to enable data roaming first, but I can make/receive calls, sms, mms, and cellular data.
I've also been able to force a connection to LTE. However, when I do this sms, mms and calls don't work (data only).
Basically there is no transition between 3G and 4G.
I've messed around with the build.prop to see if I can get the phone to treat 4G as the preferred connection and only use 3G for sms, mms, and calls but I havent made any progress.
I'm confident that with help from the dev community we can actually get this thing working fairly well on vzw.

Did you pull the VZW apn xml file from a VZW phone and swap out yours? I can send if needed. I would like to buy OP3 and I use Verizon, so I'm definitely interested in what you're trying to accomplish.
What do you mean by forcing LTE? Setting RAT to LTE only?
Sent from my rooted and BL unlocked LG-H830 using XDA-Developers app

The APNs appear to have auto configured (attached a screenshot).
When I say "forced into LTE" I have manually changed the RAT to LTE only. This only appears to only work consistently on CM based roms. I did get OOS to lock onto LTE once but I've not been able to do it again.

If you set RAT to auto do you get both CDMA and LTE? On stock vzw phones, it seems multi APNs are used (VZWIMS and vzinternet)
Were you able to unlock band 13 (http://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059)? What LTE band are you connected to? LTE Discovery app from play store can provide that info if you need.
Have you tried:
telephony.lteOnCdmaDevice=1
ro.telephony.default_network=10 ro.cdma.home.operator.alpha=Verizon ro.cdma.home.operator.numeric=311480 gsm.sim.operator.alpha=Verizon gsm.sim.operator.numeric=311480 gsm.operator.alpha=Verizon gsm.operator.numeric=311480
Sent from my rooted and BL unlocked LG-H830 using XDA-Developers app

I have not tried any of those things.
I'm hesitant to bother with attempting to unlock band 13. I spent a lot of time working on that on my opo1 and didn't work.
But I'm willing to give it a shot. I'm on vacation and don't have access to a PC so gonna be a few days. But I can apply the build.prop edits in the next few hours.

I made the build.prop edits you suggested jhasty01. Unfortunately they had no effect.
I'm going to work on unlocking Band13. Because I'm a market that is almost 100% covered by Band4 it is difficult to tell if Band13 is actually working. Perhaps I could disable Band4 but I'm hesitant.
I'm really hoping some of the devs who have worked with RIL can land a hand.
The larger obstacle is getting the RAT to conditionally handoff.

Any updates? Hoping so, would like to buy!

Some possibly helpful information from https://forums.oneplus.net/threads/trying-to-get-op3-working-on-verizon.452925/
Not sure if this is the case for Verizon but it is a known issue for ATT customers have LTE connection issues.
CAUSE: The IMEI for both sim slots are listed to only be set to receive 2G (H), hspa network. So if you contacted your service provider and registered your sim card with either of OP3 IMEI's, then you will not get LTE.
WORKAROUND: get your service provider to put your IMEI back to a previous phone that had LTE service.
NOTE: I had the same issue because I had to get a new Sim card because I went from a microsim to a nanosim. You access your phone information, by dialing *#*#4636#*#*. It will show your "Network type" only as hspa instead of LTE. There is no way to force it to LTE on your end, you have to contact your service provider.

Make sure you enabled roaming!

*Update*
Using qpst+qdxm I attempted to set radio/modem to prefer vzw bands and possibly enable B13. I was able to make the changes but the NVRAM resets to default values after power cycling. There is an NVRAM patch for the OnePlusOne which I flashed but it did not play well with the OPO3 and resulted is reboots and black screens. I tested all this on one of the recent CM builds.
I modified the build.prop to force "LTE only" (ro.telephony.default_network=11). Since I use Google Voice/Hangouts for calls and text I can make due.
I have reached out to @Mentor.37 who has been helping patch CDMA phones with GSM caoabilities to work better on GSM networks. He understands what the goal is and said mid-late August he should be able to help. @jhasty1 I only get 3G/eHRPD when roaming is enabled. No matter what ROM the RAT will not automatically transition from 3G44G. I have tried almost every ROM and modified what I thought might help with in the build.prop.
@jhasty1, as for the thread you mentioned (https://forums.oneplus.net/threads/trying-to-get-op3-working-on-verizon.452925/) there is a lot of conflicting information. There are many who say the OPO3 will not work on VZW. Well it is working, I'm using it to write this. I also had the OPO1 working on VZW using B4 LTE data.
As it stands, unless forced into "LTE only" the default RAT is 3G/eHRPD.
If we get some dev support I believe the phone could work very well.

I've been able to attach to LTE on bands 2,4 and 5. Now as far as I know vzw has not began using band 5. I think what's happening is I'm roaming on att for some reason.

Volte T-Mobile

Ive had my pixel xl for about 10 days. I noticed yesterday that I'm dropping to Hspa or 3g when I make a phone call every time. I want to say that I had no problems prior but I honestly don't know. Anyone else on Tmo have any issues? Orlando FL here

Enable enhanced 4g lte mode on cellular network settings volte works for me.

Should come on by default when it detects the TMO SIM. Check your cellular settings and apn info to make sure it's current.

Shoot mine is doing this as well. What build are you using? I'm using the "P" build on a Verizon variant. I'm in ft Myers, FL.

Using P version as well on Verizon variant works well T-Mobile NYC.

Must be something going on in FL with the network. I'm on the L build with a Google store variant. I have enhanced 4g toggled.
I called T-Mobile and the tech I was transferred to (not the rep) told me that it shouldn't stay on LTE that the phone was acting fine. I just said ok and hung up. What a schmuck.
So I then decided to use the built in support feature and requested a phone call. The Google rep said to give it a day or two. Might be a network issue. If it persists then to call back.

What APN do you use? I was using the default one but I was having MMS issues so I decided to switch to the one the T-Mobile suggests on their website. All seems to be working well now. I'm confused by the default one since it has three entries. One is for IMS and the other for MMS, I have no clue what IMS is.

What ever it defaults to.

I don't make alot of phone calls, but I just noticed volte wasn't working. 3g and H was showing during the long phone call. I thought it was working a couple of weeks ago. On V build. Enhanced LTE toggled on.

Like I said it comes and goes. I don't know if something is causing it but right now it's working for me. Could just be Tmo running maintenance on the network. Just keep an eye on it

Is VoLTE + Pixel/XL + T-Mobile still intermittent? For me, it's not working at all. It's fine on other phones.

Since the latest update it hasn't been working. I think I'm going to flash the factory image and completely wipe everything

VoLTE appeared for me after a reboot. WiFi calling has always been working. I will test later to see if a VoLTE call is using EVS. BTW, I'm running the Dec build.

Keep us posted. I'm still confused as to why it's so hit and miss.

VoLTE has been consistent since my reboot. I have been traveling so it is working in different places. One disappointment: The CODEC is AMR 12K rather than EVS, as confirmed by the lack of "HD" logo during the call.

I get HD during call when I talk to my wife and anyone else that is on a compatible device

The EVS claim to fame is that it is enabled whether the other side supports it or not. On a T-Mobile branded phone (or a phone running native T-Mo ROM), so long as VoLTE is available, every call will show the HD logo and the CODEC is EVS.

I was having a similar problem with VoLTE not working. I reset the network settings on the phone and then toggled the advanced calling off and back on and it has been working fine since then.
