Radio is legit, but no LTE (TMOUS LTE market).

Hope .33 will work with 4.3. Otherwise, it'd be worth exploring if the newer radios can be patched :\

BTW, my neighborhood went live yesterday (5/24) :):)
[Nexus 4 General] iGoogleNexus:
Well I'm pretty sure this new radio won't give Users LTE since it was patched in .48 But doesn't hurt to try and tmobile has lte in a few markets... So maybe a Tmobile user with lte in their area can test this out. If not we can all stay below .48 =]

[Nexus 4 General] VacTacks11:
Sorry guys, no LTE here with Telus Mobility on this new radio. But we kind of expected that
[Nexus 4 General] Redneck Trash:
Correct. The .48 radio doesn't support LTE. , You'll need to flash an older radio. Personally I've had GPS issues with the current radio but I seem to be in the minority with that issue.
[Nexus 4 General] Nethojs29:
Hi, I'm new on this of radios and in less than a month I'll get a unlimited data plan so I was thinking is time to get 4g.

It's just flash a radio? It doesn't get problems with kernels, roms?

*edit* k phone booted and I have full signal. Guess I'll try it for a couple days and test it out :)
[Nexus 4 General] nellisere:
I've just installed it but wanted to see if anyone else had tried it for a bit longer, so far its about the same, not really noticed a difference.
[Nexus 4 General] Razer(x):
Flashed it, previously had .27. No noticeable change here. Don't know if there's any in 3g/H switch
[Nexus 4 General] trillo69:
What things should be tested after flashing a radio besides wifi and signal?
[Nexus 4 General] Razer(x):
3g/h switching, since H drains more battery it's important to came back to 3g in idle
[Nexus 4 General] androidjack5:
I just tried. Radio. 54 full signal but don't let me get LTE, im on NYC so i go back to radio. 27 and LTE works great. Algo i try radio. 33 and seems lots data drops for me best working radio for now is. 27 very stable.
[Nexus 4 General] Ace42:
For those of you with LTE, have you updated the bootloader to the new version? I ask because I am not picking up any LTE with .27 in areas others have found it.
[Nexus 4 General] androidjack5:
T-mobile US, New York

Bootloader: MAKOZ10o

Radio:. .27

Band works; H, H+, LTE

Also flash the file to fixed the call audio issue on lower radio with t-mobile , so everything works

[Nexus 4 General] bdubs4200:
so im on 4.2.2 (as everyone should be by now) and i was using the .48 , getting 5 to 15 data dropouts a day, killing phone calls failing downloads and such, so i flashed .27 reading that helped alot of people but i dont hear audio in calls... i rememeber reading about this but i cant find a fix for it... do i need to downgrade to 4.2.1 then flash .27 radio or what? any help would be great.
[Nexus 4 General] Tylog:
No downgrade need ( 4.2.2 to 4.2.1 ), you can flash from 48 to 27 directly

Try flashing the T-mobile no-audio fix, and see if that fixes your issue. (I don't have a link handy, but just click on the paperclip icon beside the LTE thread in the General section, and it will pull up a list of attachments.

Anyone do speed tests with the .54 radio?
[Nexus 4 General] ac21365:
I decided after reading most of this thread that I'd give .27 a shot since general consensus seemed to indicate that speeds were much faster... So, I decided to flash it and test it.

The site I used is a "re-farmed" T-Mobile site here in town that's live with WCDMA on AWS (DC-H+) and PCS (single-carrier H+) (also 'sneaky' LTE, but Csprings is far from fully re-farmed). Parked about 1/8 of a mile from it with direct line of sight.

On the .48 and .33 radios, I could -never- speedtest better than ~16mbit down on stock and CM 10.1 roms.

So, went and flashed the .27. First speedtest: 20mbit down. Second speedtest here.

I speculate that it's a DC-H+ issue since on the .33/.48 radios, and with my AT&T iPhone 5 using the PCS WCDMA, they all top out right around 16mbit.

Hmm...
[Nexus 4 General] xuggs:
So LTE is supposed to work only in the US with .33 and lower radios? No love for the rest of the world? I tried .27 and it's got faster speeds than .48 IMO but does anybody else feel the device getting a little warm with .27?

Just to make sure I am not doing something wrong, here comes the n00b question.. to get LTE speeds.. what do I need to do? I have enabled LTE/GSM (auto) from Phone information (*#*#4636#*#*) and do I need to change anything on my APN? If I set the bearer to LTE in my APN, I get no signal at all. It only works with unspecified but it only hits H+ speeds.. did a speedtest too!

Educate me a little please!
[Nexus 4 General] Ace42:
1. It's not just for US, also works in canada for example...

2. Change APN for LTE according to your provider

3.do not change Bearer in APN, leave at default

4. You can use LTE/GSM
[Nexus 4 General] ac21365:

I had a signal crash this morning with .54

My phone asked me for sim code again.

It happened in an area where 3g signal is weak.

From Australia.... New radio.... I'm impressed :D

Although our data is crappy compared to the US.... Wish I could get LTE... Bah.
[Nexus 4 General] eRajesh:
The Indian version of Nexus 4 ships with Android 4.2.2 JDQ39E. The only interesting thing in it is the radio, and nothing else. Kernel date is March 12th.

If I find anything interesting, I will definitely let you guys know.
[Nexus 4 General] hp420:
I have been having some seriously bad signal issues for about the last month or so, no matter what radio I use. I have tmo prepaid, and I live in a good hspa+ area. However, I can see my signal (voice & data both) go from totally full, to minimal coverage, to nil in about 15 seconds, then straight back to full....all while the phone is sitting perfectly still on the table.

The other day I flashed .54, and that has almost entirely stopped!! I still have spotty coverage and I lose my 4g occasionally, but the 4g signal does come in stronger, and my voice signal is a steady 3/4 bars. Google needs to push this baseband, even if it's the only thing they push!! I know a ton of people are having the same issue with N4 on tmo I was, and this has made my signal far better....not great...this isn't a magical fix!! But it is definitely a vast improvement over the last one.

btw, I don't live in an area that's got LTE yet, so I can't test that. I do occasionally travel within an area that people have reported spotty LTE, though, so if I do happen to go there I will be sure to report back!

works, but it isn't very accurate. maybe I need to calibrate it??

*edit*

nvm....I had GPS off lol :p It works perfectly now, and it locks a location very fast!!
[Nexus 4 General] VivaErBetis:
Thank you very much!

I think that kernel is interesting too since ”actual” JDQ39 (without the E at the end) kernel is from Jan 29th. Maybe it has WiFi problems solved...
[Nexus 4 General] efrant:
Agreed. Maybe someone could provide a dump of the boot image, recovery image and a system dump (in a new thread of course).
[Nexus 4 General] philidor:
When you use "4g" are you talking about LTE? I think .54 don't have LTE.

I can't test it I have not LTE but I this is my speed test. Similar to .48 maybe a little better. I need more days to evaluate battery consumption and signal strength.
[Nexus 4 General] hp420:
no, by 4g I'm referring to hspa+. there are three officially supported speeds on N4 with tmo: edge (2g) hspa 10 (3g) and hspa+ 15 (4g). LTE is LTE ;)
[Nexus 4 General] TheManii:
JDQ39E is interesting, as it's new.

Would it be possible for you to make a nandroid of it and to list the bootloader version?

We currently have nothing on it except for the baseband you provided
[Nexus 4 General] mongonexus:
thanx guys for posting new radios, flashed 54 gonna give it some time, testing here on the jersey shore, bayville and toms river,,:good:
[Nexus 4 General] mariosraptor:
Flashed 54 a few hours ago and it is giving me better reception but it is struggling to give me hspa. I will try till tomorrow and report back but I have a feeling that I will.have to revert cause as I see it, it is like using 2g only.
[Nexus 4 General] efrant:
You are correct, but the N4 will not show "4G" for HSPA+, it will show "H". It will show "4G" for LTE.

[Nexus 4 General] efrant:
That's exactly what I said, no? :confused:
[Nexus 4 General] philidor:
4G is the fourth generation of mobile phone mobile communication technology standards.

I think that LTE is a 4G standard but HSPA+ isn't

So is normal to have 4G on a LTE network.

@ efrant On N4 we have 2G, 3G, H (HSPA+), 4G (LTE), I'm right?

And can you confirm that .54 don't have LTE?

Sorry but I want to be sure to understand it.

Thanks

You need to be using either the .24, .27 or .33 radio to be able to use LTE (Band 4) then go into the dialer and type *#*#4636#*#*, click phone information, scroll down and choose one of the LTE options.

No delay here; took around 6 seconds for a text to get sent from my phone and to be received by myself (same device). Maybe 10 seconds to text my Google Voice number on my Nexus 10. No failed messages (yet anyway).

Pretty much, nothing out of the ordinary (or different at all really) with this .54 modem. Still get good signal in my house, no signal in another place, same data speeds, recieve texts and calls.
[Nexus 4 General] santeana:
Yeah nothing new here either. I wonder if it's the same radio, just badged for India? Wouldn't be the first time they've done that. Well with other phones I've owned anyway...
[Nexus 4 General] styckx:
The .54 baseband solved all my crappy data issues and stalling downloads the .48 baseband gave me.. It's a damn miracle!

Edit:

I LOVE THIS RADIO

I've downloaded over 500MB of files without a hiccup. This was IMPOSSIBLE on .48 because the download would stall out a few MB or so into the download and eventually timeout.. My pings are all insanely low now too. No more triple digit pings!

I always see great speeds on this thread, but wonder why I never get great throughput on either h+ or lte with usually about 85 dbm. My usual average is south of 5 kbps on either. And lately worse even with a good signal. I'm on the. 27 radio, rassaber, t mobile everything correctly configured
[Nexus 4 General] manulemaboul:
To be 100% accurate, neither H+ nor LTE are 4g. LTE is the most advanced 3g, it's 3.99g, but still 3g technology.

[Nexus 4 General] Juggalotus:
Actually Radio has a lot to do with Rom on the N4. Seeing as I'm one of the lucky few that the Modem breaks continuous focus. Granted it may all work properly, but there are some exceptions.
[Nexus 4 General] shotta35:
LTE is a 4th Generation Technology which is why they have to build a completely new network vs upgrades from 3G (UMTS) to HSPA to HSPA+.

What you and most people confuse 4G for is by thinking it's a speed determination (I blame the carriers!!). LTE is 4G but it's not "4G" speeds that were thought to come aka 1Gbps when not moving. 4th Generation Mobile Interface is more efficient than 3G for Voice and Data calls. LTE is only being used for Data now while calls still use the WCDMA (not HSPA+) protocol.
[Nexus 4 General] nellisere:
Just did a quick check, as .27 broke continuous autofocus in 4.2.2 recording, looks like .54 fixes the focus problem in video when going from close up, to normal, it no longed gets stuck in "macro", not sure if this is definitely the radio fixing it, but I'm just assuming that it is seeing as the radio affected auto focus before.
[Nexus 4 General] PelegK:
Thanks alot.

[Nexus 4 General] manulemaboul:
4G is allowed only as a commercial name due to its evolution potential, but it actually doesn't match all the 4G specs, and I don't remember talking about speed.

What 4G is, is actually arbitrarily decided by a bunch of people that don't really know what they're talking about: the ITU.

I can clearly hear my interlocutor with it, without any cuts at all from anywhere in any room. It's a first time ever for a cell phone in that apartment actually.

To make you see what I'm talking about, you only get edge here, H+ as soon as I'm out, but edge only inside.

Correct LTE, as it is now, is below 4G standard, but faster then H+. But we are little of topic now ;)

I'm testing .54 but don't have find a real difference with .48.

Normally I have good signal strength at home and work so don't feel the difference between two modem.

[Nexus 4 General] espionage724:
I flashed it to my US-purchased Nexus 4 without issue, and it works fine (in my case, I notice absolutely nothing different compared to .48 on T-Mobile).

There's a risk of losing all your data when you reboot your phone; pretty much, there's risks associated with a lot of stuff :p There's even the chance that flashing the radio would brick your N4 by wiping the bootloader. But with all that in mind... I don't see floods of people reporting broken IEMI's and Basebands after flashing modems, so any issues aren't to be expected :good: (but the standard disclaimer does apply; doing non-official stuff with your device may cause instability, not covered under warranty, may cause a black hole, only you're responsible, etc.)
[Nexus 4 General] zivan56:
That's not correct. There are files inside the radio named WCNSS.b01 .b02 ...

They are the firmware for the WCNSS (WiFi and Bluetooth) subsystem.

I believe the consensus its its using the WCN3660 module:
