Who is running 3.4X radio's on Verizon?

Did you think it was an improvement over 3.37.78 or not? Any better GPS locks?

Hello. I am running ROM 1.15.VZW & radio 3.42.30 & no GPS signal. I went thru the whole process of unlocking it but it looks like there is no luck. I still don't get any signal. I even waited outside in open air for 30min under the LA's heat but no signal. Maybe I did something wrong.

I'm running that newest radio and I haven't noticed much of a difference at all. Maybe some weird radio bugs were fixed, but nothing you'll see in day to day use. It's not really worth the trouble, IMO.

I am not sure how we can unlock the GPS on Verizon touch. I went thru all the steps of unlocking and still there is no signal. Any body out there that have tried this to see if it really unlockes the GPS or not?

This personally worked for me on my Verizon XV6900: LINKY
The attached cabs in that post are both GPS registries, not to be confused with the carrier cabs. Pick from the two, I recommend the Telus. Also I said V13 in the post, but obviously you should flash the latest ROM when you finish flashing everything else.

There was a thread on this very same issue a little while back, the consensus was there was virtually no difference between the two, despite the larger number the 3.42 radio was in no way really 'superior.' In fact, some people reported better reception on 3.37. Having used both, I would agree they're indistinguishable.

i get 6-8 locks in google maps within a minute and im using 3.42.30

I'm on Sprint... And I use to use 3.42.50 and my signal was not really good. So I recently switched to 3.37 and my signal is great... I have a question, is it not smart to use a Verizon radio on sprint..?

I used .50 bell for many months. Switched back to VZ radio a few weeks ago. A very slight increase in reception. I can go about 3 feet further in my house and still talk than I could with the bell radio. No real diff though.

[Q] Flashing GT-N7100 with T-Mobile ROM for Wi-Fi Calling??

Hello all,
I have an international version Note II (GT-N7100). I am on T-Mobile in an area where most of the towers now use the 1900mHz band. I'm wandering if I can flash a T-Mobile branded ROM to get the use of Wifi Calling, which I've cherished the ability to have (sometimes with hacked apks and libs), on previous phones. Would flashing one of these ROMs work well with my version of the phone? Or if even better, is there a package I can get like THIS that will push the wifi calling to my phone?
If it is workable for me to flash one of these ROMs, should I be flashing a radio as well? Or any other tips to make this conversion work out?

Do not flash an LTE Note 2 modem on the non-LTE version, they have different hardware. I know there were some porting guides to modify ROMs to go from one to the other, so this won't be a straight-forward flash.

You should be able to flash t-mobile roms and get the Wi-Fi calling feature.
I am using it on my AT & T note 2 and Wi-Fi calling is working flawlessly.
Try Tweaked ROM from T mobile note 2 section and make sure you keep your existing RADIO/Modem.

Thank you both for the replies. I will try to get one working. Had some issues for a couple days recovering from trying Android 4.3... lol I like to experiment.

Curious as well
I bought this international version as well I live in the states and have been using it with att but now I'm about to switch to tmobile. I have rooted the phone but I am curious if I can flash it with a stock tmobile version of firmware (where ever that is) and use it with our services here. I understand Ill need to reset the counter and all that crap too. I have experience with rooting and installing CFW's but having a tmobile stock firmware that will accomplish things like wifi calling and ota updates would be very beneficial at least until that final firmware update is released then I will probably root it again.. real shame they wont let you OTA update just for a simple root but then again I guess with warranties and law suits and the chance of screwing up your possible custom firmware maybe its a good thing. Anyways point me in the right direction HAHA. The phone is amazing so far and works flawlessly with the towers here. Thanks. I checked the tweaked firmware for tmobile seems like it might work like you said but Im extra cautious at times and so I would like to know If what i stated above will work ok or not ???? Its not a huge deal if i cant have ota updates but yeah I would def like to have wifi calling and maybe some of tmobiles other things but yeah Looking forward to some advice

Same issue here

Were you able to get the software on your N7100? I am curious as I would like to know how to get it done as well. thanks in advance.

Calling all non-ATT E980 users - I have a question

Assuming you apply to the criteria listed in the title, I'm wondering what modem do you use? I'm on T-Mobile using CM12.1 and I use the M915A (stock kitkat) modem because the suggested B915A (madmack) modem gives me issues. It seems like my service drops quite often with that modem, which makes me miss calls and send/receive texts late. I also tried C915A (stock jellybean) modem and experienced the same issue. However, I don't experience this with the M915A modem, but likewise I can't get into deep sleep since I'm not using B915A I don't believe this is linked to my area, as it seems to follow me where ever I go (unless it's my entire state lol)
Is anyone else experiencing this? Or am I just plagued

I am on SlimLP and I use stock jb. Sometimes I lose signal, but it is much less than on the previous version. However, I don't think it is critical as few people mention they cannot reach me.

Do u get deep sleep? And watch your service bars for about a minute...do you lose service at least once?

I do get deepsleep and no service lost in two minutes.

Hmm that's interesting, and you're on e980 on T-Mobile?

@Emmanuel U e989 in Brazil. TIM the Italian carrier.

@Emmanuel U I have received complaints my cell signal is always off. I will try 4.22 e985 modem and f240 lollipop modem. Let's what happens. I'll let you know.

Might be your location. I first started on T-Mobile when I got e980. Stock kk I was always losing signal in some areas, but perfect signal in a different area. And yep its the entire state. Used to do a lot of driving for a company so I was everywhere in the state. I then rooted and unlocked bootloader. Loaded up bliss I think with madmack, and had same issue, one area great while other area horrible.
You could try calling them and get them to up the signal, helps a bit.
I'm on cricket right now and I believe it uses att and aio so signal is great, unless you head north in my state. Can barely get signal the more north I go

TMo firmware on ATT hardware??

Is it possible to flash a TMo ROM, Stock?, on my old ATT SM-900A (OC1) in order to get WiFi calling? I am a new T-Mobile customer and using my old hardware for the moment. Wifi calling is a huge deal for me in my weak service area.

No, it is impossible to flash stock TMo ROMs on AT&T's phone as far as I've read:
Here
However, I think there might be some ports of TMo software (custom ROM) for AT&T phones (which include Wi-Fi calling)
As seen here
I am NOT responsible for anything you decide to do at this point. I am giving you the resources to do your own research. I do not own a AT&T Phone and have no way of testing it out myself, proceed with caution.

I have flashed with TWRP (hlte) a N900TUVUFOB6.zip ROM and have WiFi calling, working on my Sprint Note 3 with a T-Mobile SIM. Installed, setup and did a backup. I restore it when I got WiFi but no cell signal. Not my daily driver but works.
Are you sim unlocked?

I'm not too familiar with the AT&T N900A Note 3, but I know about would need to be done. Now if I remember correctly, nobody was ever able to unlock the bootloader on that device, and that is definitely not good. Hopefully I'm wrong though because it would be fairly straight forward if the bootloader can be unlocked. You'd need a recovery like TWRP installed so you can flash a kernel, Safestrap won't work for that. If you could flash an actual full T-Mobile N900T ROM that includes the baseband and kernel, it should work. The N900A and N900T is almost identical except some of the network bands supported. I've looked some, and I'll look around a little more, but so far I haven't seen a single N900T ROM on a N900A device and it have functioning Wi-Fi Calling.

I know that ROM won't work the way he needs it to. The actual Wi-Fi Calling components have removed from it. I read through it and no one was ever able to get it functioning at all. *shrug*

There is no way to unlock the n900a bootloader and probably never will be. The phone is still a great device imho but it's considered old in the rapid pace of cell phone hardware.

That's what I thought. I didn't think the BL was ever unlocked on AT&T's variant, and you're correct, if it's not unlocked by now it's pretty much guaranteed it'll never happen.
I definitely agree that the Note 3 is still a great device. I'm still rockin' my N900T with it set up like the Nexus 6P/Pixel XL. And this little Snapdragon 800 can still get down. The phone is only really lacking stuff like camera hardware with OIS. But it's still really good if you don't use stuff like auto-focus. It'll turn out great pictures if you know how to manually adjust settings.

the only phone that is att that can be flashed to tmo that I know of is the galaxy s4 because they are the same phone but this i've no idea

Upgrade radio baseband?

My Verizon M9 has pretty crappy reception. This really became apparent last night when I was at a restaurant with my wife and son who both had 2 bars on 4G and I barely had 1 bar on 1G.
I've tried a few things to fix this including cache wipes and full resets. No change. Toggling airplane mode hasn't helped either.
So, I'm hoping that someone could tell me if it's possible to update the baseband radio by itself, without flashing a new ROM or firmware? The attached screenshot is what I currently have.
Thank you.

Are you all on the same carrier with the same phone?

Hi. Thanks for the reply. I was getting worried that I was on my own with this one
Yes. Everything is Verizon.

I had Verizon replace my SIM card. Only marginally improved.
Still not what it should be.
