Yeah you can just flash it in recovery as far as I know there is a file in the .zip that tells it what partition to flash too.

Will flashing a new ROM erase my lte setup? I did the setup to have it permanently stick on boot. My question is do I have to do the entire procedure every time I flash a new ROM?
[Nexus 4 General] xdviper:
Would the new radio (54) be responsible for the low ear speaker volume that my phone is suffering from? I can't hear anything its really low. Anyone have any ideas on how to fix as well?
[Nexus 4 General] Dan1234567890:
It could help if it gives you better signal... But if you want to increase incall sound you can flash custom kernel (for instance franco) and with kernel tweaker app (trickster mod) you can increase volume i think... :thumbup:
[Nexus 4 General] fone_fanatic:
Most likely yes. ROMs overwrite the build.prop. But most aren't packaged with a radio so you might not have to re-flash that.

Once you flash a ROM just remove "telephony.lteOnCdmaDevice=0" from /system/build.prop and add the following to /data/local.prop

"telephony.lteOnGsmDevice=1

ro.telephony.default_network=9

ro.ril.def.preferred.network=9

ro.ril.hsxpa=5

ro.ril.gprsclass=12

ro.ril.hsdpa.category=24

ro.ril.hsupa.category=8"

After doing this and if you're just doing a ROM update all you have to do is the first part, removing telephony.lteOnCdmaDevice=0 from build.prop.
[Nexus 4 General] anshumandash:
Just a general question, I want to flash .54 radio. In case I get in to problem, can I just flash back .48 to get everything back as it is? I mean it wouldn't change anything else, Right? I see many people have flashed both .54 and .48. So it should be safe to do that.

I don't want to get in to the trouble of flashing factory images to get back normal radio. Just trying to clarify. :D
[Nexus 4 General] atxbang56:
you can flash all the radio without any problem. If you want I have uploaded .27, .33, .48 and .54 on Mega.

[Nexus 4 General] sid21:
well i am from india

i have seen alot things abt .54

can anybody let me know what does it improve?

im on pa latest 10june build

sometimes wifi problems and dont receive msgs when the phone is locked

does it cure that? and what else?
[Nexus 4 General] Dan1234567890:
I doesn't cure push notifications delay... That will hopefully be fixed in new android version.

It can cure/improve your signal strength/speed, you can try and see it if it can help you...
[Nexus 4 General] jmartino5920:
Wondering if you could help me. So I have 4G LTE setup and working just fine on my phone. However, I did not edit my build.prop the way you described.

I didn't know about having to add these four lines:

ro.ril.hsxpa=5

ro.ril.gprsclass=12

ro.ril.hsdpa.category=24

ro.ril.hsupa.category=8

If possible, would you be able to explain why these lines are necessary? I'm asking because my device gets LTE fine but not having those lines in my build.prop makes me worried that something my go wrong down the line.

Thanks in advance!

Really they're optional, some say they don't do much, I just put them in anyways. They tell your phone max capability of your network. What GPRSclass it can handle, HSDPA, HSUPA, HSPA or HSPA+ etc.

[Nexus 4 General] toxicbubble:
For me, in a relatively low coverage area, I've found .54 to be heaps better than .48 and .33. It used to just hang for up to 10 seconds before loading anything, the speeds are far more consistent with .54. No more hangs or stutters, things load much much faster.

For the record, this is on 2degrees in New Zealand (which is a 2100MHZ network).
[Nexus 4 General] chigro:
Bell + 0.27 = Better speeds and ping

For those coming in from google or search, I'm confirming that 0.27 has better speeds than 0.33 for Bell towers in Toronto.

Average difference was around 1000kbps in both upload and download, and ping difference was about 10ms; both in 0.27's favour.

See sig for my setup.

Hey, this is a noobish question so I apologize. I have the Nexus 4 on T-Mobile's pre-paid plan. I'm running Paranoid Android version 3.60 with radio .48 and I'm dropping calls within a minute of making them constantly over the past two weeks or so. Would updating the radio possibly help? If so, which one?
[Nexus 4 General] gravitysandwich:
Update to .54 try it, if nothing try franco's r155 kernel. Because pa Franco kernel has some issuies and Franco merged some patches in r155 dealing with radio and stuff.

What's a good radio for AT&T HSPA+? Still .27?
[Nexus 4 General] gravitysandwich:
Well the latest one(.54) or .48 for hspa+ of course.
[Nexus 4 General] sirxdroid:
Why is .27 so loved? Does it matter on AT&T or just for T-Mobile? I'm on AT&T and no chance for the LTE band where I live so it's AT&T HSPA+ only for me.
[Nexus 4 General] gravitysandwich:
I have no idea. I guess it works best for some people. There is really know explanation since we don't all live in the same area or were all right next to tower. Or sometimes it's just the ROM or lte. Or the battery. Or the signal strength. Just my opinion.
[Nexus 4 General] chigro:
This is absolutely correct. In the end, it's DEAD SIMPLE to change radios, so testing out radios for your particular situation (ROM, Kernel, Mobile provider, Location relative to towers, etc) is almost trivial.

Here's my quasi-scientific method of testing which radio is best for me:

Download a bunch of radio images.

Install the speedtest.net app

Flash the first radio (takes less than a minute, and you don't have to do any wipes)

Get a pen and pad.

Enable LTE (that is if you have LTE and if your ROM doesn't automatically do this for you. Google is your friend)

Run the speedtest.net app 10 times, taking not of your ping, download, and upload results each time. Also take note of which speedtest.net server you used for this test; you want to use the same server for subsequent tests.

Flash the next radio and start from step 5.

Find the average result for each radio.

Keep the radio with the best result!
[Nexus 4 General] sirxdroid:
Thanks. I see your winner is .27 :)

I'm on TMO in the US.

.33 has worked OK. Not the best reception of the three. Definitely the fastest downloads (10mbs) without lte. LTE goes even higher.

.48 is the Goldilocks. Reception is fine, downloads around 6-7.

.54 has great reception but downloads are stuck to 2 or under. Tried rebooting and reflashing but downloads remain slow. I know some kernels recommend this radio but it's just not TMOs cup of tea.

[Nexus 4 General] atulalvenkar:
Not sure. Since ril libs aren't open source they need to either be used from Google site or pulled from devices. If CM team has used the ones from Google site they are JDQ39.

If they have pulled from devices running JDQ39E then you are fine.

Either ways haven't seen much of a difference. My notification delay problem has improved a lot but I can't attribute that wholly to the ril change.

Anyone else seeing weirdness with Auto Rotation after flashing the .48 radios?

I don't know how a radio firmware could have anything to do with Auto Rotation, but when I'm running .48 (with perfectly fine signal and everything) I lose Auto Rotation (the settings under display are turned on).

Confirmed that flashing back to the .33 radios causes Auto Rotation to work again.

Re-flashing my ROM and Kernel on .48 Radios did nothing.

Anyone else?
