For anyone having trouble keeping keeping your weak "fringe" signal alive such as myself, ive found a few things that have greatly helped me:

Decrease mtu(max transmission unit) across the board, add this script to init.d:

#!/system/bin/mksh
sysctl -a 2>/dev/null | grep -i mtu 2>/dev/null | grep -v " 0" | awk "{print \$1}" | while read i; do sysctl -w "$i=300" 2>/dev/null; done >/dev/null 2>&1

Add these to /system/etc/mkshrc so you can run them when needed the terminal, terminal ide or jackpal's etc

Functions are a radio reniceing/priority function and a radio daemon restarter for when the radio goes dead.

function radionice {
(( USER_ID )) && return
for i in $(pgrep ril) $(pgrep net) $(pgrep ifconfig)
do
renice -n -19 -p $i
ionice -c 1 -n 7 -p $i
done
}

edit: Restarting the rild daemon here will cause a temporary break in data connection, so only use with dead connection

function radiorestart {
(( USER_ID )) && return
radiooptions 0
({ ulimit -e 1; ulimit -r 1; "$(whence -p rild)" -l '/system/vendor/lib/libsec-ril_lte.so' -- -d '/dev/ttys0' 2>/dev/null
}&)
setprop 'rild.libargs' '-d /dev/ttys0'
# setprop 'net.tcp.buffersize.lte'
#'327680,655360,1310720,163840,327680,655360'
for i in $$ $(pgrep ril) $(pgrep net) $(pgrep ifconfig)
do
renice -n -17 -p $i
ionice -c 1 -n 7 -p $i
done
}

I also finally completed removed nfc from my device (software and hardware) to enhance received signal:

Block/turn off software device:

#!/system/bin/mksh

# NFC POWER OFF
print '0' >| /sys/devices/platform/nfc-power/nfc_power

# Disable nfc device
chmod 0000 /dev/ttyO3
busybox chmod 0000 /dev/ttyO3

To strip out system components, you need to make sure and get all of these. Remove in recovery/aromafm preferably to avoid a system crash:

/system/app/Nfc.apk

/system/framework/com.android.nfc_extras.jar

/system/etc/nfcee_access

/system/etc/permissions/android.hardware.nfc.xml

/system/etc/permissions/com.android.nfc_extras.xml

/system/etc/permissions/com.cyanogenmod.nfc.enhanced.xml

/system/etc/permissions/com.nxp.mifare.xml

/system/lib/libnfc.so

/system/lib/hw/nfc.tuna.so

***Leave any other nfc files NOT listed.

The nfc device is just a security-hole-gaping, battery-draining flat coil hooked into the battery under the battery tape. To remove the device, take a scalpel or sharp blade to peel back the tape, cut the coil from the battery as close to the battery leads as possible, and re-cover the battery's tape.

This seems to definitely have stabilized my weak 4g signal. I got one stable usable bar almost all day inside now instead of the crap intermittent unusable 0-bar signal I had with nfc. That nfc coil seems to create so much interference.

BEST radios for stabilizing weak 4g are definitely FK-02s/4.2.2. Combining FA-02 3g/cdma and FK-02 4g/lte is just as good. Make sure to dial "*228+,,2" when upgrading radios for the PRL.

I use my data connection 95% time, so signal this is critically important for me.

That's
[Samsung Galaxy Nexus] 7175:
Hey guys, been experimenting some more with improving connectivity and speed of the data connection. I've found that there are actually some tcp congestion algorithm tunables in /sys/module/tcp_*/parameters directories. There are none for westwood but a handful for cubic. I've found so far that changing hystart_low_window value to a lower number seems to have improved my connection speed and connectivity (less timeouts), as tested with Network Tester and browsing.

I've only really tested this with some significance on tcp_cubic so far, but I'm sure optimal values could be found for other tcp congestion algorithms that have tunables in /sys/module/tcp*. To change the values, just run "echo value > path_to_value" in terminal; e.g.:

echo 4 > /sys/module/tcp_cubic/parameters/hystart_low_window

This cubic tweak plus the previous tweaks I posted has made my data very usable with 1-2 bars. I encourage people to check out tcp tunables, especially if your kernel has a bunch of tcp's to chose from like Dirty V. Almost all kernels will have cubic to try this tweak though.

Any chance the newest flashable radio can be hosted somewhere??? Seems like links are all d-e-d dead
[Samsung Galaxy Nexus] Damacles:
I do have a question. My phone never shows the right signal it always seems two bars off or so. It's rather annoying to look and see no bars but yet I can still go online and make calls without issue.

What can I do to fix this?
[Samsung Galaxy Nexus] mark manning:
That sounds like it may be rom related. What rom are you using? Have you been on that one the whole time that this issue has persisted?

Anyone having issues with the phone not staying on 4G unless you manually toggle it? My phone has full bars but 4G won't stay. I switched roms flash different radios and the same thing. Any ideas on how to fix this
[Samsung Galaxy Nexus] mark manning:
No, I'm going to keep it just the normal updates.

[Samsung Galaxy Nexus] Damacles:
It's been like that since I have had the phone, they even sent me a 2nd one because of the issue but it had the same problem so I sent it back. I have put liquid smooth JB on since then and the issue persist.

Wasn't this the same issue the phone had when it came out? I though Verizon and Samsung were have suppose to fix this.

I am using the latest JB radio.
[Samsung Galaxy Nexus] mark manning:
Not quite, what Google "fixed" was the rom showing the accurate signal and everybody freaked out think they had low lte signal. They really didn't. In 4.0.4 Google changed the way bars show so ppl would stop freaking out. However, I don't remember anyone saying they had issues quite like yours. That's really weird. I'm assuming you have flashed the other radios to the same effect? Also have you tried anything besides the liquid rom? Maybe a good wipe and some CM10?

[Samsung Galaxy Nexus] Damacles:
I will give it a shot, can't hurt. I'll let you know what happens.

how do i find MD5 on my phone?

[Samsung Galaxy Nexus] Sleerts:
Anyone confirm these radio match the official ones that are dropping today via the official release? I want to stay with CM10 but have the updated radios.

Thanks.
[Samsung Galaxy Nexus] Eschmacher:
This. Anyone checked to see if the radios in the official release are the same as the leaked ones? The leaked ones have been causing more trouble than the 4.0.4 ones did.
[Samsung Galaxy Nexus] vicw:
The Root Explorer app will also calculate & display the MD5 value. Just long press on the filename & select Properties. It may take a few seconds to calculate.
[Samsung Galaxy Nexus] jss2:
I checked the CDMA radio, and the bootloader. The update didn't have a complete LTE radio file, just an update file to patch the previous LTE radio.

The CDMA radio is identical to the one that was leaked a little while ago. The bootloader is identical to the leaked version (which is also identical to the official bootloader for maguro).
[Samsung Galaxy Nexus] Eschmacher:
Nice, hopefully someone can find a way to get that LTE patch to us without having to flash the stock rom. LTE is the only thing I'm having trouble with.
[Samsung Galaxy Nexus] jss2:
Although I haven't yet confirmed it, I would be surprised if the LTE radio in the official update is any different from the LTE radio that was leaked a few weeks back. Are you already using those leaked radios?
[Samsung Galaxy Nexus] Eschmacher:
Yeah, about once a day or every other day my data freezes up and I have to cycle airplane mode or reboot.
[Samsung Galaxy Nexus] efrant:
Here you go. The attached CWM-flashable file patches the IMM76K LTE radio to the new version, and flashes the new CDMA radio.

Notes:

1) I haven't tested this out as I don't have a toro device... :)

2) This will only work if you have the IMM76K LTE radio flashed.
[Samsung Galaxy Nexus] mark manning:
Anybody still have the radio files? If so, please host them, ping me, and I'll add them to the OP for the community.
[Samsung Galaxy Nexus] purplepenguin:
I'd really appreciate if this happens. I'm working on these devices for a friend's kids as their first phones & using Lineage/locking them down pretty severely. Have an issue with one of the two (bought from same seller) that she got for some reason. About to be troubleshooting & I don't know your level of nerdiness but I found this zip (titled VZW_JDQ39_radios.zip) when I initially set them up (mid August), flashed it (can't remember if there were errors or not, I think 1/2 devices was on an old baseband) but I'm about to take the device back to try getting it buttery smooth like the other device.

It's running at 65% awake when checking wakelock detector and other than normal things you'd expect, her settings/battery menu shows Android OS using 8% battery with cell standby at 3%. This is in a context where almost exclusively Screen & Textra (SMS) are used as nothing else exists on the system haha. Praying a ROM/G-apps/SU update/reflash will be all that's necessary but kinda worried it's related to the baseband zip.

WHICH FINALLY brings me to my question and ties back the nerdiness level - When I pop into that zip, extract the CDMA/radio IMG files and attempt to mount them in Windows, is it normal to get an Error - image corrupt or something like that? I've never attempted to do this before. Everything else about the zip seems normal to me? (As a 100% pro flasher but 0.01% pro at... coding knowledge and in-depth technical knowledge of android operation.)

Sorry for rant + some OT from a very old device in a very old thread but would appreciate any help as it's difficult to find living links to various flashable things I can try : *( Of course if it makes more sense you can PM me and flag this for deletion!

edit: FeelsAwkwardMan (feels like shouldn't be asking questions here) but also - her other device that IS buttery smooth actually has the baseband from the OTA prior to JDQ39 so now I'm even more worried about the dead links haha hopefully someone has! *pray emoji*

edit 2: these mediafire links for JRO03O are alive! Won't know if they work until I receive the device I'll be working on though. https://xdaforums.com/galaxy-nexus/verizon-develop/radio-jro03o-radios-bootloader-t1860304

I can flash back to the 4.0.4 ones from the leaked ones, correct? And then I could apply this?
[Samsung Galaxy Nexus] efrant:
Yup, for sure.

I haven't actually checked though if these are any different from the "leaked" ones. My gut sense tells me they are the same.
[Samsung Galaxy Nexus] Eschmacher:
Can't hurt to try! Will report with findings.
[Samsung Galaxy Nexus] mark manning:
The updates in the OTA are the same as in the leak from a few days ago.

FF02 / FG02
[Samsung Galaxy Nexus] Eschmacher:
Confirmed, versions on leaked and versions from the above zip are identical.
[Samsung Galaxy Nexus] marc.ientilucci:
any chance they can be pulled from the official release anyway? maybe the names the same but something else could have been tweaked? :confused:
[Samsung Galaxy Nexus] mark manning:
They wouldn't keep their version number the same if that was the case. When the factory image is posted on Google I'll pull the radios and post them.

are they safe to flash over the ones i already have?
[Samsung Galaxy Nexus] aggrophobik:
Yes.
[Samsung Galaxy Nexus] efrant:
As I stated in a previous post, that zip will ONLY work if you have the IMM76K radios currently installed. It patches the LTE radio to the latest version, and flashes the CDMA radio. But yes, safe to flash.

But, as was stated by other previously, what this zip updates your radios to is the same as the radios from the "leaked" update.
[Samsung Galaxy Nexus] mark manning:
Yes but only because it is no different than flashing what you did before. Your basically just reflashing the patch over the same set of code it was meant to patch in the first place.

[Samsung Galaxy Nexus] Flapjack:
I have a question about radios and Bluetooth connectivity.

Ever since buying my Verizion gnex, the noise over my bluetooth earpiece has been terrible. When I talk over bluetooth, I hear a buzzing, electronic sound in the background (not unlike an old dialup modem). The noise is oftentimes louder than the caller, and even "warbles" the caller's voice a bit.

If I take the call off bluetooth and simply use the handset, all the problems go away. I also do not hear this when using my bluetooth stereo headset for audio (though if a call comes in on that headset, the call will be just as bad as with the single ear bluetooth device).

There is a few pages of fervent discussion on the androidcentral forums. A few people in their consolidated "bluetooth noise" thread has indicated that the FA02 radio is the best for resolving this. It didn't seem to help me much.

So just what exactly controls the bluetooth portion of the device, and is it even possible that a new "radio" could help?

You can extract the flashable radio images from the JRO03O factory image (posted on Google) using 7 Zip. Only takes a few minutes.

[Samsung Galaxy Nexus] efrant:
I'm not trying to be mean here, but either:

a) You really don't understand that the "leaked" radios (which were not leaks by the way) are exactly the same as the radios from the factory image, despite it being mentioned here more than a few times, or

b) You are trolling, and misleading people by implying that the radios are different.

If you really don't believe us that they are the same, I don't understand why you don't download the factory image yourself, and just flash the radios?

I was unaware that radios had anything to do with WiFi or GPS, particularly since they reside on separate hardware components within the device http://www.ifixit.com/Teardown/Samsung-Galaxy-Nexus-Teardown/7182/2 (this is a GSM teardown, but you get the idea). I've found the GPS to respond quite fast once you get past the first fix (always takes longer), and WiFi is blazingly fast with JB on my VZW GNex.

[Samsung Galaxy Nexus] efrant:
Radio firmware should not have anything to do with GPS, although I suppose A-GPS (which runs through the cellular network and assists in getting a faster lock) could be affected.

There was no need. But spunks3 did not believe that the radios from the OTA update were the same as the ones from the factory image, so, I pulled them out of the factory image and posted them.
[Samsung Galaxy Nexus] marc.ientilucci:
no need to point fingers... if people look back at the posts they can see who requested the radios... you could have simple said a fellow xda member. (and i do appreciate u pulling them for me btw :) )

Thanks
[Samsung Galaxy Nexus] mark manning:
1. You can check to see what radio you have in the about phone section under settings. From there it is under baseband

2. Unless your on stock you have to update your radios manually. However, if your on a stock rom and you get an OTA from Google radios will then update automatically.

I think that's answers all of your questions
