Download: New Radios From Galaxy Nexus LTE 4.2.2 Update

galaxy nexus radios

The new radios from the Android 4.2.2 (JDQ39) for the Galaxy Nexus LTE on Verizon that was released tonight are now available in .zip form. Thanks to XDA member mwalt2, this file should be flashable over any current G-Nex radios as it includes the full radio.img.

With little testing thus far, it’s tough to tell what kind of difference these can make it network connectivity, battery life, etc. If you are willing to take the risk and do not feel like leaving your current custom ROM, feel free to give them a look. Understand that the CDMA radio will take a while during the flashing process.

Flash the .zip file in your favorite custom recovery.

Cheers adbFreedom and Steven!

    My signal is drastically worse now

    My results.

    Location: Walla Walla, WA

    4G: LTE:13
    -99dBm 41 asu, 3 bars
    -100dBm 40 asu, 3 bars

    3G: CDMA – eHRPD:14
    -83dBm 4 asu, 3 bars

    1x: CDMA – 1xRTT:7
    -83dBm 4 asu, 3 bars

    4G: LTE:13
    -98dBm 42 asu, 3 bars
    -106dBm 34 asu, 2 bars
    -103dBm 37 aswu, 3 bars
    -105dBm 35 asu, 3 bars

    3G: CDMA – eHRPD:14
    -83dBm 4 asu, 3 bars

    1x: CDMA – 1xRTT:7
    -83dBm 4 asu, 3 bars

    From what I can tell, it looks like signal strength is improved, but by only ~3-7dBm. Since these new radio basebands/drivers don’t really effect speed, I didn’t compare that.

    • Cory Larson

      You signal strength got worse by 3-7dBm, not better. The units are negative; the lower the number the worse the signal.

  • Hey guys getting errors when executing the side loader?

    This should take care of errors when sending the zip file over. This worked on a Verizon Nexus just fine.

  • Drootz

    Ok So probably a dumb question but can I flash these radios while running CM10.1 or do I have to go back to stock to flash the radios to work properly? Thanks All

  • eazyean1

    my Chrome is loading up pages???

  • Michael webb

    Has anyone had problems with tethering with these new radios?

  • joejoe5709

    I was excited to flash this except some of you said the radios might actually be worse. Sounds like battery life is better so that’s good. I think I’ll wait for the weekend before doing this. Glad to see Verizon updating us though!!

  • RW-1

    Flashed this morning, handoffs seem faster, didn’t expech much improvement in reception, though I have to say I have good to fair reception where ever I am locally. Overall I’m pleased with it.

  • Guest

    This is probably a stupid question (because i know this is from verizon ) but does this work on Sprint LTE version as well?

  • wagner

    Can you make another posting to whether or not it is beneficial to flash the new radios?

  • JS629

    Aren’t these included with the 4.2.2 update?

  • Justin Kos

    There is a post on xda about ‘myths’ that radios do and don’t ..its a good read. Speed has nothing to do with radios

  • Brandon Golway

    Didn’t make any difference for me, actually made signal strength slightly worse.

  • Justin Barrett

    Has there been an actual significant improvement for anyone?

  • gpzbc


  • chuckfu

    Any thoughts on why the zip won’t take for me? I install them and all seems fine from recovery. It takes a few minutes to write the CDMA radios as expected, then finishes with a message saying “Install from SD Card complete “. But when I reboot and look at my build number, it still says JZO54K. I’ve tried 3 times and get the same result each time. In case it matters, I’m still running CNA 4.1.2 (I’ve had bad luck with the 4.2 ROMS I’ve installed). Any ideas?

    • antinorm

      You’re installing radio firmware, not a new ROM. Go to Settings – About Phone, and you’ll see FK01/FK02 now under Baseband Version.

      • chuckfu

        Oh geez- you’re right. Thanks!

    • silly guy

  • TheDrunkenClam

    When the new bootloader becomes available can you please post that too? Currently it’s PRIMELC03

  • Cory Larson

    Before: -93 dBm, 47 asu
    After: -90 dBm, 50 asu

  • Lucas

    Anyone else notice that their signal bars aren’t blue anymore? I flashed the radios over the Evolution ROM and my signal bars are now grey – but I have connection (tested browser, sms, and twitter feed) … interesting eh?

    • Brian Inglut

      Blue means that you are connected to Google services. Try opening the play store or gmail it shouldn’t connect. Probably need to reflash gapps package

      • Lucas

        Works now – just took a little while to connect to Google.

  • Neil Anderson

    can these go over any ROM? Does anybody have a link to the old radios for those, just-in-case moments?

    • NorCalGuy

      The first thread in the Vz GNex form on XDA has every radio the phone has ever had including 4.2.2

  • Jack Hoffman

    Don’t know about battery life yet, but:

    Before: -95db
    Down: 9587kbps
    Up: 6317

    After: -83db
    Down: 11199kbps
    Up: 6339kbps

    • schoat333

      I had the same jump in signal strength. Not speed difference tho.

    Nothing special here. VIA speedtest.net I remember when LTE was twice this.

    • Go to Highland Heights, KY across the river. Holy hell, I get the fastest speeds there on LTE. Last week on Friday I got 48666 down and 15422 up.

    • Cowboydroid

      It’s slowed down to a crawl here in Dallas. I can rarely get over 6-7 mbps, and it’s usually down around 2-4. I remember when I was getting 20-30 mbps just a year ago.

    • I’m still on 4.1 stock and am getting 10809kbps down and 6072kbps up here in Cincinnati – to PowerNet Global. Again, this is not with the new radios.

    • Justin Kos

      Radios are more for 3 and 4g handoffs

  • RampageDeluxe

    I normally run around 80-85dbs in this spot. Since flashing the zip, I’ve been at 107 for 3 hours.

    • Cory Larson

      That’s bad though, right? Signal is measured in dBm and should be a negative number. The higher (less negative) the better. Your signal got worse by ~20 dBm.

      • RampageDeluxe

        Yeah its bad. Its been worse everywhere I’ve gone today. Places I normally have full bars is down to 1 or 2. I could just be a special case or there could be something wrong with Verizon in my area. That would be very crazy timing though.

  • Sean Quinlan

    I never really understood what exactly flashing a new radio does. Can it actually give you better signal strength or faster data speeds?

    After flashing this new radio, my signal strength and data speeds were about the same as before. One thing I noticed though was that switching from wifi to 4g was instantaneous, I thought there was a little bit of a hiccup when I’d switch between the two in the past.

    • florious80

      I have been testing all of the past radios for Gnex because I was getting very weak reception at my office. The signal strength definitely is effected by which radio you use. I think data speed is not effected by which radio, though. THere’s also the 4g/3g handover issue that some may have and a radio update has fixed it in the past.

    • PhoenixPath

      The hope is that it will make it so that we no longer sound like we’re chewing gravel and the calls won’t drop every 2 minutes…

      • You and the gravel again. If you don’t like the phone get a different one.

        • PhoenixPath

          I did, but thanks for the advice!

          I do, however, still have the G’Nex and as soon as the OTA hits, well…we’ll see. I may or may not start using it again. As it stands the replacement (LG Spectrum) is now officially supported by CM 10.1, but I’d still like to actually be able to use the device I paid $300 for on release-day as, like, a phone…n’ stuff.
          Oh, and if you don’t like this comment, read a different one. 🙂

    • RW-1

      simple, radios are the firmware for the cellular radio chipsets within your phone. these do not get updated when you flash a ROM, or bootloader, but are separate. So in essance you are updating the software that runs the hardware – think updating drivers on your computer.

      • Jarrod Bush

        Radio is the wireless transmission of signals through free space by electromagnetic radiation of a frequency significantly below that of visible light, in the radio frequency range, from about 30 kHz to 300 GHz.[1] These waves are called radio waves. Electromagnetic radiation travels by means of oscillating electromagnetic fields that pass through the air and the vacuum of space.

        So actually we are updating the radios. The firmware is an antenna or radio receiver if you will. Radio RECEIVER being the operative word as it receives radio (waves). But you are right in that it is software.

  • JoeInMO

    Be careful with these radios. Verizon will be able to track tethering even if you don’t have a plan.

    • bose301s

      They could ALWAYS track tethering, it’s called Deep Packet Inspection and all major ISPs employ it and there is pretty much no way around it. Also, why would these radios make a difference?

      • michael arazan

        They can also track you through GPS and towers so what?

        • bose301s

          And that has what to do with tethering? I was just pointing out that the new radios don’t mean anything for tethering as they never had a problem detecting it before.

          • kg215

            yup don’t know why joeinmo implies that this radio is different from the others in regard to tethering.

          • John Davids

            Also, even if there was a difference….VZW doesnt charge extra for tethering anymore…..

          • What about on unlimited plans?

          • Just don’t abuse it and VZW won’t care. During Sandy, I lost my home connection, so I tethered. I used 5Gb in 1 week, and I was never charged for a buck extra. Speed wasn’t throttled either.

          • Confirmed. I don’t abuse it at all, only use tethering in an emergency (Sandy — no power for a week). No notice from Verizon at all. Of course, I wasn’t streaming Netflix, just checking email and websurfing to keep up to date on news and weather.

      • burntcookie90

        Run your phone through a VPN if you want to hide your tethering.

      • Ryan

        DPI is still easily worked around for anyone with knowledge in TCP/IP

    • Source?

    • Jon Picking

      It is illegal for Verizon to block/charge extra for tethering on tiered data plans.

  • Aaron

    I’m seeing a slight improvement in 4G reception(slight improvement in dB)but 3G looks identical so far. Anyone know what the asu means?

    • Aaron

      Actually after watching it for a while my 4G is actually around the same(104 dB) and my 3G has been about 10db better(83 vs 93). Who knows though, could just be the signal or any number of things at the moment. I’ll have to see how it fairs outside of my house and what battery life is like.

  • YES!!!!!!!!!!! new radios!

    • This excited about radios. Really?

      • Adam

        Yes, that excited. It’s about the only thing on the Galaxy Nexus that still needs help.

      • TheOgler

        I know I just went from 1-2 bars to 3-4. Getting off the LTE/3G threshold is very exciting.

      • My battery life has been amazing on standby so far with these new radios. I’m running cyanogenmod 10.1 M2, trinity kernel, the new FK01-FK02 radios and I’m at 92% after 3 hours of the phone being on.

        • I am scratching my head here — I’ve never had problems with the battery life at standby (I’ve used stock, CM, Bugless Beast, and now Shiny.) I had done an experiment: I tethered my Nexus 7 to my Galaxy Nexus for a whole day. After 11 hours, the GNex still have power left.

          My battery life problem has to do with the display — every time the display is on, battery life drains like a toilet leak, even when I set the brightness down below half.

  • Prime7

    Alright. I’m down. Will post results at some point.
