I'm just the messenger. Proceed at your own risk.

[CDMA][Radio][Bootloader]4.0.4 IMM76K Radios and Bootloader - xda-developers

Haven't had a chance the flash yet. let me know how the radios seem after the upgrade.

I read in that post, btw, that someone flashed that fine over AOKP M5 with no problems.

Verified :thumbup: and an improvement so far!

Paul1201 · May 2, 2012

Flashed these radios using ROM Manager last night and they are working fine.

BTW - for the first time ever my GNex has more bars of 4G reception than my Xoom. A quick Speed Test run shows my Xoom 1 mbs faster than my GNex (17.8 vs. 16.8 download).

I thought the 4.0.4 radio and bootloader were already available somewhere else?

that was from the old .4 that leaked. A new .4 leaked yesterday with updated firmware.

Flashed the radios last night. I'm on Baseband v. I515.09 V.FC04 / I515.FC05 now.

Doesn't seem any different than the previous FA02 baseband. Which I didn't expect it to do much. Maybe help transitions between 3G/4G areas, but I live and work in a 3G only area and haven't had a chance to test that out. With the FA02 radios, it would sometimes still not transition to 4G unless I toggled data/LTE.

I wouldn't expect a software to magically improve signal strength though. Fortunately that's never really been an issue for me on my Gnex though.

Paul1201 · May 2, 2012

I happen to be flying across the country today so I figured I'd check to see how the new radios work in the different locations. The first test was at Reagan Airport in DC. In Phoenix my GNex shows 4 bars and Xoom shows 2 but the GNex was faster on both download and upload (7.3 vs. 6 and 3.4 vs. 2.6). Seems like the GNex maybe over rating the signal a bit.

Yeah, there was the whole uproar a while ago about verizon saying they were going to adjust their signal strength reading to consistent with their other phones. Which at the time meant, showing the signal strength to be greater than what it really is. No idea what they actually implemented though.

I'd prefer accurate reading, even if it's crappy.

Definitely seeing an overall improvement in signal integrity. Not only are the dbm readings better in and around the metro Atlanta area, I also drove through a burb where it has ALWAYS dropped to 3G for about 5 minutes then switches back to 4G. It stayed on 4G the entire time albeit -110/-116 dbm strength. Didn't matter though I had a nice fast connection to Phandroid

Also, I see a much more animated (think busier) dbm meter which to me seems like it is more accurate, or trying to be more accurate through different locations. So far, so good!

your the second person that i've read that specifically mentioned a more active dbm reading. As if maybe it has sped up the way in which the radio updates. This is a good thing.

WishinItWas · May 2, 2012

I flashed the radios, at work I have always shown -75dBm so I will have to see if I have better signal strength in my apt when im home as that is where it has been weak in the past.

mihalich · May 2, 2012

Great. Just getting around to pulling it down and installing it now.

Joe

iwoloschin · May 2, 2012

I flashed mine a few hours ago. When I checked the battery page in Settings, since I flashed it's been almost all green. That never happens. I haven't actually used the phone apart from a quick phone call, so I can't confirm if there's actually a difference or not.

I can confirm the old 4.0.4 radios were better than the 4.0.2 radios, I had my brother's brand new Gnex next to mine, and his couldn't pull AOKP M5 down, until I realized I hadn't upgraded the radios. I didn't expect it to be that drastic, but hey, I'll take any free improvements!

mihalich · May 2, 2012

The 3G-4G hand off seems somewhat quicker.

The 4G-3G hand off is still lame.

Joe

trophynuts · May 2, 2012

what about hand off between Cell and Wifi and then Back

example

your at home using your home wifi
you want to send an mms (picture text message)

how does that work? that is one of my biggest issues.

When I'm at home (now) and send an mms (now) nothing ever switches it just sends it. Takes about 6 seconds to send a big pic.

From 3G to 4G is instantaneous with the newest radio. From 4G to 3G takes 10-15 seconds for me. Doesn't bother me one bit

edit: My MMS has always worked that way regardless of what radios I'm running and I've been on them all

jbdan · May 2, 2012

mwalt has a ROM out for those that want to try it

*could add it to your OP mihalich

funkbucket007 · May 2, 2012

Have better reception (per the bars) than on the previously leaked 4.0.4 radios. In the fire station I'm working in today, I'd normally have 2 bars but after flashing the new leaked radios, I have 3, sometimes 4. Hand-off seems better but I did have to do a restart once today to get an MMS to send. It showed three bars of 4G but no "up/down" arrows in it and wouldn't send. Switching to airplane mode and back or toggling 4G on/off didn't fix it...it just kept saying "sending." After a reboot, it worked fine.

Steven58 · May 2, 2012

I'm gonna flash this now.

Steven58 · May 2, 2012

This is weird. At home I'd normally get up to 30 mbps d/l. At work with the new 4g I'd get up 2.5 mbps d/l. With the new radio I'm getting 8.1 mbps d/l. Weird. Is this possible?

How does yours work?

djc999 · May 2, 2012

Just flashed the new radios over the leak and saw no difference

the7nd · May 3, 2012

I have been using the new radios for the past few hours and things seems to be running really well so far. I am not turning on my phone to see I can't use data because of the switch from 3G-4G or vice versa.

couldnt send MMS over wifi before i rooted, still couldnt while rooted running aokp m5 and leaked 4.0.4 radios, still cant using aokp m5 and official 4.0.4 radios...bummed.

also im noticing very little difference in the amount of bars i am receiving, still zero bars at home though i can make phone calls etc without dropping

Yeah, ya can't use the bars as an accurate measurement. At least I don't believe you can.

So you've never been able to send mms? Ever?

mms is not sent over wifi. It's sent over your mobile data connection. Are you saying that when your connected to wifi you can't send mms, but if you turn wifi off so you have the 3G or 4G or even 1X icon in your status bar then you CAN send mms?
