[Nexus 4 General] sjgore:
I just had to downgrade from 84 to 48 to get HD voice working in the CM 10.2 nightlies.

So either: CM10.2 nightlies don't support HD voice with the 84 radio yet, or the 84 radio itself doesn't support HD voice or is broken. CM10.1 supported HD voice right from the very first nightly, but that doesn't necessarily mean anything.
[Nexus 4 General] Xoib:
What do you mean by HD voice ?

Over GSM cell tower or by using viber/skype/ or ?
[Nexus 4 General] sjgore:
HD voice is a normal phone call, not a data call, but at a much higher quality. It needs a supported HD voice-compatible phone (Nexus 4, SGS3, SGS4, HTC One, etc) at each end of the call, and a supported network (like Three Mobile in the UK).

HD voice almost sounds like you're stood chatting with the person in the same room, rather than a muffled low-quality typical phone call.
[Nexus 4 General] Xoib:
Ok that something I didn't heard before. We don't have that in France.

Either we call through GSM (no data needed, only fix to a cell tower) or internet call (via a SIP account - data needed) or internet call (via an app like viber/Skype/ data or WiFi needed).
[Nexus 4 General] bakedpatato:
Interesting. Did you do any build.prop editing? I've been unable to ever get hd voice to work on .33.
[Nexus 4 General] sjgore:
No special steps required for HD voice, no settings either. It just works.

Are you sure the receiving handset was HD voice compatible when you tried it? Both ends needs to be. Network needs to support it too. Why not try the 48 radio?

[Nexus 4 General] sjgore:
I think I've answered my own question:

I flashed the .84 radio and CM 10.1.2 stable, and HD voice works fine. Back to the 19/08/2013 10.2 nightly but keeping the .84 radio and HD voice breaks. Flashing the .48 radio back again restores HD voice. So it's almost certainly CyanogenMod that's the issue, not the radio.
[Nexus 4 General] n2d551:
How do you know if you are getting hd voice anyway. My call quality on tmob is all ready sounds good. So how to tell the difference
[Nexus 4 General] sjgore:
Believe me, you would know. It sounds like the person on the other end is stood in the same room as you.

Read this: http://en.wikipedia.org/wiki/Wideband_audio
[Nexus 4 General] Xoib:
It say that Orange in France have it but seriously I can't tell if I have HD Voice when I'm calling but it's okay.
[Nexus 4 General] bakedpatato:
Yeah, the other end is a TMOUS SGS3 and it's using the 12.6kbit AMR codec. I suspect HD voice is broken in the 33 modem in general as I've never got 33 or 33/88 hybrid to get hd voice. TBH I'm getting 10mbit from LTE(5 mhz channels ftl) so H+ shouldn't be a big deal so I guess I'll try out 48.
[Nexus 4 General] Ace42:
Like he said you'll be able to tell due to the bump in quality. It's like going from 64 mono rate music to 320kbps

Stereo.

Think it works on .27 radio hybrid.
[Nexus 4 General] Xoib:
I have always been able to understand very well the phone communication so I can't tell.
[Nexus 4 General] a.f.x.:
.84 issues

Same issue here (Germany, Vodafone).

I had stock 4.3 and now moved to CM 10.1.2 but the radio is still .84.

The phone often goes from blue to grey bars without any connectivity.

Stock 4.3 was problematic connectivity-wise, but this is even worse.

cheers

Had the same problem on 4.3 stock.

I just installed CM 10.1.2, but still have the 4.3 radio (.84) which seems to be wonky.

[Nexus 4 General] mbadge:
I'm glad to see this. I noticed this happen on my phone maybe 2 or 3 times...didn't think much of it as it reconnected 10-15 seconds later. It may happen more than I notice however, so I'm looking forward to seeing an update in the near future to fix this bug. Anyone else notice this loss of cellular connection at all?
[Nexus 4 General] thebrainkafka:
Not in .83 and cm 10.2
[Nexus 4 General] otariq:
I've been experiencing that bug too. Even with full bars it will drop to no signal an come back a few seconds later
[Nexus 4 General] occtec:
So if your running 4.3 can you use a 4.2 modem? If so which one is best .48 or .83?

Cheers.
[Nexus 4 General] :
You can. IMHO the best is .54.
[Nexus 4 General] outz:
what improvements do you notice from .48 to .54?

Better connectivity in low-signal areas.

[Nexus 4 General] daerragh:
.84 radio prevents me from booting. The phone stays at boot animation infinitely. No matter the ROM I have, it won't boot with .84 radio.

This is serious. I even flashed official JB 4.3 images with fastboot and the phone didn't boot with 84 radio. Then I flashed official 4.2.2 images (and .48 radio) and updated it to 4.3 over WiFi and the phone didn't boot either, because of the radio.

This is weird. Some time ago I had .84 radio and it worked well with any ROM. Then I installed Doom III for Android (a game port), lunched it and all of a sudden my phone restarted and didn't boot. Now it won't boot any ROM when I have .84 radio.

How could this happen? Anyone knows how to fix it? Do you think my Nexus' modem might be broken?
[Nexus 4 General] occtec:
Boot into recovery, wipe cache then dalvik. Install .84 radio, fix permissions then wipe cache & dalvik. Reboot ;)

Is it okay to flash these radio's if we are using the latest TWRP recovery? I thought I might have seen people saying they were having problems with it when flashing radios but do not remember where I saw it. Am I better off using CWM or have people been successful with the latest TWRP?

I haven't heard of anyone having trouble using TWRP to flash these.

TWRP is great! That's the only recovery I've ever used on my N4; never had any issues flashing radios, ROMs, etc
[Nexus 4 General] djdeeles:
For better battery life which modem do you recommend?
[Nexus 4 General] efrant:
I would recommend that you try each one for a few days and see which one gives YOU better battery life. (Battery life will vary depending on your usage, so a radio that gives one person better battery life, may give another person worse battery life.

[Nexus 4 General] username8611:
Have you tried flashing a radio through fastboot instead of a flashable zip? You shouldnt have to, but maybe try using "fastboot erase radio" then flashing a radio... I dunno
[Nexus 4 General] daerragh:
Yep, I did try to erase radio, it didn't help. I even fastboot flashed stock 4.2.2 and let it update to 4.3 via OTA and then it ROM didn't boot because it updated radio to .84. When I flashed .48 radio, it booted OK.

I tried to flash .84 radio through fastboot and flashable .zip. Nothing works.

I've had .84 radio before and it worked really well but later on my phone hanged and rebooted itself and from now on I can't use the radio with any ROM.

Any ideas?
[Nexus 4 General] RandoTheKing:
Anyone know when the radio update will be released to fix the Nexus 4 randomly dropping the mobile signal?
[Nexus 4 General] mor_1228:
its an obvious answer which was not needed. if this was the case i would have done it myself but i am asking about experience of people.
[Nexus 4 General] efrant:
Actually it is an answer that is not so obvious, and actually is needed. The performance of radios is not only dependent on the carrier and country. It is dependent on user-specific usage patterns, installed apps, immediate surroundings, network congestion, weather, etc. That is why asking for someone else's opinion on which radio is the best is, for the most part, completely useless.

Try each radio out for a few days at a time, given your typical usage, and compare them. That's really the only way to determine which is better for you.
[Nexus 4 General] arlenwoot:
Like efrant said, there's too many variables involved. What works for one person might not for someone else, even if they're in the same area. You need to test for yourself and your usage.

I also don't want to end up with the wifi delay notification bug again, but I've heard that the radio has some affect on the wifi too (wifi chip firmware blob?).

Can anyone confirm if these radios will muck up the wifi again and if so which ones are OK to use?

Hey guys,

I can't seem to get LTE working for my Nexus 4. I just flashed to LiquidSmooth 3.0 and Purified Kernel r153. I flashed the LTE Enabler and then flashed the .33/.84 Hybrid radio (I was on .33 before) and have the APN settings (fast.tmobile.com) and Network settings (LTE/GSM auto) set up, but it just doesn't seem to want to connect to the network.

I was on LiquidSmooth 2.9 prior to this with the .33 radio and had LTE working beautifully.

Starting about a week ago, I've been having some watchdog problems. I used to think it was the kernels I was using setting me back, (Faux ver 025 at the time). I isolated the issue to only occur when my apps would try to auto-update over wifi. I switched kernels and then would get reboots instead of watchdog bark screens. I figured hmm I've been dirty flashing PA updates for a while now so I could use a clean install thinking it would resolve the issue. After I've done that, I still get a few random reboots here and then when updates occur. I'm using franco kernel but with no tunables set on boot at all. I currently am on and have been on the 33/84 hybrid for a while now, is it possible the radio or my modem is just not up to par?

As Ace42 said, all the stock radios are available in this thread.

I'm in the same boat. I've tried .27, .33, .27/.84, .33/.84. No discernable difference. However connecting to LTE gives me a noticeably better connection than H+ (at least in my apartment). AT&T's coverage was superior, but a get a lot more bang for my buck with T-Mobile, so I'm dealing. ;)

The reception of this phone is indeed pretty bad. My old blackberry was much, much better in this respect (and only this, I must say) as well as my wife's old Nokia (she's got a N4 as well).
