VERIZON GALAXY NEXUS RADIOS
Hey guys!!
Im am not sure why no one else has not done this yet but I felt it was about time we had our own dedicated radio thread. Some of you may wonder what a radio is and others may have misconceptions as to what radios do. So let me try to make this clear and simple for all of you. So in a nutshell a radio driver is what allows your phone to communicate with the cell tower, similar to how a printer driver lets the computer and printer communicate with each other. Keep in mind it's a lot more in depth than that but you should now have a basic idea as to what they do.
I would also like to take the time to clear up some common misconceptions as to what radios do and don't do. Now most of this is fact, it is not just an opinion so if you have an open mind you can learn something. However, if you try to argue with me you better come up with a valid argument explaining why you believe what you believe. Different radio firmwares will more than likely NOT give you a stronger signal. Before a phone is released it is excessively tested before being released to the public. During this time the carrier/s test how much power the radio antenna can safely transmit. The way they measure this is through the SAR (Specific absorption rate (SAR) is a measure of the rate at which energy is absorbed by the body when exposed to a radio frequency (RF) electromagnetic field) value and then it is submitted to the FCC. Verizon's fillings are listed as below, in order for these to be raised above this the phone would have to be resubmitted to the FCC.
SAR: Head: .63 W/kg ; Body .88 W/kg , Product Specific Use: 1.01 W/kg, Simultaneous Transmission: 1.39 W/kg - (max allowed by the FCC is 1.6 W/kg)

What they will do is control when the phone will switch from 4g to 3g to 2g. This will cause some of you to be able to hold on to a 4g or 3g signal in some place that you didn't used to have it.
Radio drivers can also change the way the phone displays a certain signal strength by changing the way the signal to noise ratio is sent to the android telephony file in the platform_frameworks_base ... EXAMPLE -89dBm 43asu used to give you 2 bars of service. If they want to service providers can manipulate this to where the phone now shows 4 bars of service. Apple has done this in the past and Verizon admittedly did this with the 4.0.4 OTA.
Default values of SNR will display like this...
The LTE signal strength level is the smaller one
between lte rsrp level and lte snr level if both
rsrp and snr are valid.
The lte snr mapping are
Four bars: SNR >= 45
Three bars: 10 <= SNR < 45
Two bars: -30 <= SNR < 10
One bars: SNR < -30
No bars: No Service

One final misconception I would like to clear up is that a radio update, assuming everything I stated prior remains true, should not make your phone's download speed faster. There are numerous variables that will cause the speed of your network to fluctuate. If you flash a radio and notice an increase in speed, whether it be small or large, you are only experiencing a placebo effect. The only file in android associated with download speeds is the build.prop file. With the exception of user traffic what I quoted below will be the biggest cause in difference of network speeds.
Reference signal received power (RSRP), is defined as the linear average over the power contributions in Watts of the resource elements that carry cell-specific reference signals within the considered measurement frequency bandwidth. Used to measure the signal of your LTE (GSM/4g) connection. In short, it's what's used to determine the best cell tower your LTE device can connect to at the given time. Anything below say -80db is considered pretty good and you're pretty close to a tower. -80db to -90db is average what you should expect most of the time. -90db or above and you're probably in an "extended network" area for LTE and getting close to a likely handoff. -105db and above you would be likely to see a handoff to 3G if your signal does not get better.
Throughput for your connection measured with LTE is estimated to decline between 30-50% if your signal goes from -75db to -90db for RSRP. Above -95db and your throughput dramatically drops. At around -108db and worse, your throughput for download drops to nearly 3G rates or worse. Note that this doesn't exactly represent how strong your signal is, just the potential of how efficiently it will send that data.
"But why can I have a super awesome RSRP signal and still my download/upload speeds are not that good (or why is it still sometimes good when RSRP is low)?"
Because it's only measuring the efficiency between you and the tower, not the rest of the network or the end source (the website). There are many network hops along the way to the destination and some may also handle connections inefficiently. The more hops, the slower the connection generally is.
However, it does also represent the greater likelihood that your connection will drop more packets of data that need to be retransmitted and thus not only slowing your connection but also causing it to have to work harder and draining more battery when it's actively downloading/uploading. That's why having it hand off is for the best than fighting it to stay on LTE. This is most likely why people always complained about the Thunderbolt having such poor battery life as no one ever saw what their RSRP was on it, only their RSSI like all other Gingerbread devices.

Now that all of that is cleared up here are your downloads :highfive:
INSTRUCTIONS:
All of these files are flashable through a custom recovery. If you would rather use fastboot just unzip the file a move the radios to your fastboot folder,
1. Download
2. Its is VERY important that you check and match the md5 sum before flashing.
3. Wipe cache and dalvik cache (optional)
4. Flash
5. Reboot
AS ALWAYS FLASH AT YOUR OWN RISK. IF SOMETHING GOES WRONG ONLY YOU ARE TO BLAME
FAQ:
1. Nandoids do not back up your radio and no you don't need to back up a radio.
2. There is no need to wipe yet I suggest wiping your cache and dalvik cache anytime you flash anything.
3. Yes you can go back radio versions if you don't like the one you are on. Just download and flash the desired radio.

Mark, thanks for posting these radios in a consolidated thread. I also think this thread might be better suited in the VZW dev forum, especially since the radios are carrier specific. Perhaps a moderator can move it for us. Thanks again for this though.

Thank you for someone finally doing this! I have one request. Can you put the baseband versions along with the OS version numbers?
Thank you for the information you provided - One question that I had that I didnt seem to notice an answer for.
When a carrier updates the Radio's firmware what are they actually changing / adding / removing that we would need an update. If its just the values to show us bars why so many radio updates.... if it has no effect on speed or signal what is happening when they update radio's.
please disregard

Lol I can see why you might say that off of what I said. I was only addressing some misinformation I have seen around. With anything computer oriented, code is constantly being updated and changed. Just like android operates better after an update so should a driver. The most recent update fixed most peoples connectivity issues with data drops. It also speed up 3g to 4g handoffs.

The thing is, the radio firmware is closed source, so unless someone works for Samsung, no one knows what changes they've made.
And while mark is correct that no firmware can change any hardware limitations (eg, max power output, antenna limitations, etc.), who knows what software limits (below maximum) are coded into that firmware, and how those are changed with each revision? I certainly don't know, and unless someone comes up with the sauce, I doubt they would know either. So while a new radio image may not do anything for performance, it may also do something and not just a placebo. No source, no real proof - - there are just too many other factors that affect signal strength and data ping/throughput.

Not really. The radio firmware that you are flashing is just that: firmware for the modem chip. It is not the "driver" that interfaces between Android and the modem.

While he is right as well, it is closed source and we don't know for sure. However, from a technical stand point to see any real improvement in signal strength you would have to increase output a significant amount. Therefore, if there is an increase chances are in won't be noticeable by the end user

Ok thinking I understand more but had another question/thought
With so many variables leading to our "download" speeds - What would you suggest would be the best way to compare different Radio Firmware.
1) Signal Strength - Mine shows -106 dBm 34 asu ( with the leaked VZ new radio firmware )
2) Download Speed - This has too many variables I think to use this but to each their own.
3) Co Worker had this thought - Drop your phone down to 3G and use the dBm from that . . not sure about this one.

What I would do (if possible) is get two devices, flash them both with the same stock ROM, but different radios. Then make sure that they are both connected to the same cell tower, and run a speed test at the same time.
is it safe to flash the jellybean radios if you're still on a 4.0.4 rom?

Hi there,
i just got my new Nexus and i'm a little upset about how it behaves.
before i had the galaxy note, testing it for about 1 week. i was very happy with the notes connectivity (GSM / HSPA+ / WiFi) and its really great screen.
however, it was just to big to operate it with one hand and didn't do it for me so i switched to the nexus. Now to the problems i'm faceing:
- GSM / HSPA+ seems to keep switching all the time for no reason? Didn't have that problem with the note tought.
- With the Galaxy Note i had a H+ inducator telling me i'm on HSPA+ and i had like HSPA+ nearly all the time. now i only (at best) get a H indicator. I checked if i'm owning the GSM & HSPA+ version and since the device name is "yakju" i'm quite sure i got it. Is the indicator missing because there simply is no indicator for HSPA+ on the nexus or is it missing because i'm not getting a HSPA+ connection? What could cause this?
- The connection quality of the nexsus seems very poor compared to the galaxy note. can anybody verify that or is it only me haveing troubles? Example: i allways had bad connection within my kitchen (Desire HD previously). I even replaced my SIM with no luck. With the Note ALL MY CONNECTION PROBLEMS were just gone! Cristal-clear calls, no interruptions (even thought the signal indicator was showing only 1-2 bars out of 4)
- The AMOLED Display of the nexsus is not nearly as sharp as the notes one. Also, when pulling the brightness level down to about 20% i get "smudge" on the screen
- when i use the ICS Live wallpaper my desktop starts lagging when i rotate between the views. is that normal? i had the official ICS live wallpaper on the desire HD, which had only one core, and it didn't lag at all (even with particles turned up to lot higher values then the default)
- Yesterday my Nexus just turned off (I'm not talking about the reboot bug, which i also haved faced like 5 times allready) and for like 1 hour i was unable to turn it on. I tried to remove the battery for like 5 minutes, putting it back in, plugging the charger in and trying to boot the device: no reaction, just nothing! After like 30 tries it suddenly just booted again, DOH!
- even thought as far as i know ICS 4.0.4 has been rolled out allready, i still got no update pushed to my phone (still on 4.0.1 ITL41D). is that normal?
Could anybody please help me to find out if that's normal? I still could replace my Nexus if its broken.
P.s.: I'm on the T-mobile net, germany.
Upgrade to 4.0.4, this will solve your issues. If you don't want to wait for it to be pushed to your phone search on the forum for a 'how to'.
Its just you.... I don't have these problems.. my nexus just shut it self down twice...everything else is perfect... the connextiom issue is odd... because I seem to get full signal everywhere except in the bathroom
Sent from my Samsung GNexus <3
first off, thanks for the answers so far.
manual update to 4.0.4 would need rooting, which voilates waranty.
so i have to wait till it comes over the air. (thought, i'm on 4.0.2 since about 2 hours now. no noticeable improovements.)
what i found out so far is that i'm currently on HSPA at best (http://forum.xda-developers.com/showpost.php?p=7893188&postcount=10 HSPA:11 indicator) which is shown by a H indicator at the notification bar.
however, i didn't see H+ indicator.
so: looking at https://en.wikipedia.org/wiki/Galaxy_Nexus the Nexus does have HSPA+. Looking at https://de.wikipedia.org/wiki/Galaxy_Nexus is sais it dosn't have!
Whats right? Is there a version without HSPA+?
What about the other problems i'm faceing:
- low GSM / HSDPA connectivity, continious switching between modes
- low performance when using the official ICS wallpaper (even thought benchmarks say everything's fine with the device itself, the wallpaper has a visible lag compared to "static" wallpapers)
would be great you guys could provide me bit more feedback if its just me so i can decide if i want to replace my nexus with a new one.
Hey,
Before carrying on I am fully rooted which may be why I don't have your Issues.
Signal wise I have noticed that the galaxy nexus' signal is slightly weaker compared to some of the other phones I have owned more noticeably poor and voice call quality is good. Perhaps a signal check in your area or call your service provider to see if they can run a signal diagnostic on your handset to see if anything faulty.
As for h+ I did a little Google of this and found another xda forum post. From what I can see there is no + symbol on the nexus and everyone gets just the H symbol.
As for your lag I agree certain ones will create slower scrolling however that's only crazy cpu intensive wallpapers. The ones he phone came with and nexus revamped etc create no Lagg for me.
Maybe your having a little more issues with your handset than I am, I know there has been a lot of issues but as people have said they are solved with the updates. Maybe look at rooting? Generally speaking it gets rid of all issues and you can always flash back to stock if needs be?

did that already. about 20KM around me i got 100% GSM, UMTS, HSDPA and even LTE coverage. Also like i said before: the galaxy note was like 100% better in terms of signal strenght and voice quallity.
any infos about the signal switching issue i got or does anyone know how the nexus switching algorithm works? i read that it only turns on HSPA+ when loading much data and switchs back down to UMTS / HSDPA later on, to save energy.
does it behave like this for GSM / HSDPA / UMTS transitions as well?
in generell i got like -100dB signal with my nexus here at my place. with the note i had like -70 up to like -80dB (so yeah, its really like 100-150% worse in terms of signal strength)

well "lag" might be miss leading. the scrolling is a lot "SLOWER". when i scroll with a static wall in the back i get nearly instand feedback. using the ICS wallpaper there is a feedback gap of about 2,5 - 5 ms AND the transitions are not that smooth (looks like way less FPS, but to realize that it would meen that the FPS drop down to below 24FPS or atleast down to 30FPS)

hmm is it possible to flash back to stock? the only way i found to flash roms manually is always using the CWM bootloader, but how to get rid of the CWM if i want to go back to stock later on?
maybe i just didn't find it and there is a way to load the 4.0.4 rom using the official bootloader (which i would perfer)
Honestly the only way for you to attempt to solve any of these issues is to root. If you are not willing then there is not a whole lot of advice anyone can give.
You can easily flash back to 100% stock if you needed to. People do all the time for warranty replacement. Some unethically, but that's a different conversation. The point is you can.
You have to decide whether or not to unlock the bootloader and root. If not, your only option is to replace it. If your willing then its already been said what you should try.

yeh thats not the problem. i would root for sure if i know the problems i got are solved.
i'm just trying to figure out if its a hardware bug / manufacturing error and if it makes sense to replace it.
repleaceing means like waiting 1 week till the new one arrives + it dosn't mean that the new one will not have other bugs which i've seen here in the forums (AMOLED display bugs for example)

Because with the case I use, I don't get any signal here at all ... without the case I get better signal than I ever had before in my flat.
Also you could try flashing another radio.
Maybe its a tower issue.

just one small insight for the op: rooting violates warranty? LOL. You don't know what you're talking about. Nope, even with locked bootloaders it's possible to root some ics versions (up to 4.0.3). Hell, you can unlock and relock the bootloader (which allows for custom roms) by using fastboot, which doesn't phone home in any way. You don't loose your warranty on a nexus phone, unless you manage to **** up the only way available to fully recover it (usb, volume rocker, power button) which is through fastboot.
change radios. your NOTE was not running ICS, and it's a SAMSUNG phone, which surely has tweaked UI/interface/radio etc. It could even be showing full strenght when it's not at full strenght, for all we know.. -70dBm NOTE, -100dBm Nexus - and you say it's 100%/150% difference? are you sure?
return the phone if you feel it's not working for you and your area of residence.

thats right, but the nexus is also manufactured by samsung so they provide the drivers, don't they?
about the dB: i forgot, we're talking about dBm here so 3dB should be like 100% drop / gain.
so no, i'm not sure anymore. but as far as i remember when i check the note it had about 80dB while the nexus is around 95-105dB.
anyway, are there any better radios for the nexus t-mobile germany ATM?
i would love to try them out.

i dont have any cellphone case except a display protection. i never dropped a phone in the past 5 years so i see no point in cases.
well, searching the web for the last 4 hours i decided to send my nexus back and buy another phone.
it seems there are alot of people out there haveing poor signal. updateing to other roms or radios didnt fix their problems.
one guy even sais he had 3 galaxy nexus and very poor signal (-107dBm) compared to his razzor maxx (-80dBm) with all of the nexus'.
seems to be a hardware problem. since my desire HD sucked in terms of radio too and i really dont need a phone that's unable to call i'll send it back.
after all i know its not me (galaxy note worked like a charm - so no provider and location issue) and its not the rom / radio. after searching the web i'm very sure its not "only my device".
maybe the guys saying they got no problems got a (rare?) working manufacturing batch or are on LTE (which i'm not).
the nexus signal just seems to be poor. and i think no update's gonna change that.
so i send it back and will grap the galaxy SIII when it's released within the next weeks. till then i'll use my nokia e65, which is like 100 years old but atleast has signal.

I am on T-Mobile Germany and as said, better signal than any other phone I ever had. (iPhone, Nokia, Motorola)
UGLA4 gave me the best result so far
Is anyone else having reception problems? My cell connection keeps dropping. NO phone I've ever had before has EVER had reception problems where I am now... GAAHHHH
Yes, there are a lot of complaints about this. Mine seems to drop once or twice a week. You need to toggle airplane mode on and off to get signal back. Usually occurs when bringing the phone back from sleep mode.
This doesn't seem to be happening with the stock ROM, just custom ones. Something to do with radio firmware voltage. I've tried switching to the latest North America radio to see if that fixes the issue for me.
That's really frustrating. I might move back to AOSP for a while.
Some people have moved back to 4.0.3 until the issue is fixed.

Triggering the Airplane mode sometimes work but it randomly just hang during the process of switching. When it get to that point, reboot is required and often I will get full signal after...
This last weekend, I was in a cottage and my friend would have full signal on her device while I would have no coverage at all... I had to get out the building to get 1 bar.
Starting to wonder if it's not simply an hardware problem since I kept the regional build on until now and that the carrier doesn't seem part of the equation.
Any thoughts?
I recently switched from the XXLA2 radio (international) to the UGLC1 radio (North America) and haven't experienced a drop yet - though it's only been a day or two.
One other thing I noticed, however, is that on XXLA2 my phone was on the Rogers Communication Network, but after UGLC1 it now says Fido.
Try either using the 7xx Mhz as minimum frequency or up the voltage by 25-50 on the 3xx frequency.
(I just replied that to another Q actually. Amazing how many people don't know / try that..)

I've actually never messed with voltages before. How would you suggest doing that? I'm on AOKP Build 4

Aokp 4!? Why don't you update to 5 at least? That might be fixing your issue as well.
I think Aokp has a kernel tinker option built in somewhere, does it not? If not, try Franco's or Morfic's kernels & apps, they have it. Or search for SetCpu here on xda, it's free for members.
Flashing a new kernel might fix it.
Hi,
I've been using JB since the version from io12 was out. Currently I use Bigxie's deodexed 4.1.1 and all is wonderful. Except one thing that is. The wifi signal is weaker than I'm used to from ICS. Especially the wifi range seems worse. Connections that I've used with ICS are now out of range. Some of my friend or family's connections are now very weak and I drop out of range very often. This goes for any JB rom/kernel I've tried.
I've tried several roms, trinity and franco kernels, dirty flashing, full wipe. I've even tried a couple of different basebands, even though I don't think they affect wifi.
So I'm wondering if other GSM GNex users are experiencing the same thing? I've seen a thread with a flashable "poor wifi fix" for the Verizon GNex, but nothing for the GSM version.
Verizon GNex wifi/gps fix:
http://forum.xda-developers.com/showthread.php?t=1739097
Any suggestions? Coukd a similar solution like the Verizon fix help?
Best regards,
P
Ok, allow me to explain whats going on with the "fix".
There were some folks who ported the GSM version to Verizon (myself included). However, they failed to use the correct wifi/BT firmware (I did but thats besides the point). They left in the GSM version. So that above fix is merely the bcm4330.hcd firmware and bcmhd.cal calibration file for wifi/BT from 4.0.4 for Verizon. It is not meant to be used for GSM and only applies to those who ported GSM to CDMA. Even with the fix, wifi is weak.
Verizon users currently have a newer version now, specifically for them from Google. However, the weak wifi issue still exists even for us. There are some who have strong wifi routers or are always close to them that do not see the issue, but it does exist for every JB user. Wifi is simply weaker, and BT is fairly janky.
It is a Jellybean specific problem, and I am assuming it will be fixed in time. You could try a 4.0.4 bcm4330.hcd, bcmhd.cal on Jellybean, but I doubt it will help, and it could end up hurting. I am thinking that broadcomm needs to fix these files.
Thanks for the reply and the precise info about the problem and the background for the Verizon fix. Very much appreciated.
I guess I'll have to wait and hope for an update.

The more I think about it, the more I think it can probably be resolved by tweaking the calibration file. However that is a bit beyond my abilities as I don't understand whats contained in it to know what it needs tweaking to.
wifi weakness
I'm not sure why it does this but when I am in my house about 15 feet away from my router I would notice my wifi signal dropping down to 2 bars where my other phone would stay at full strength until I got around 15 yards away.. I decided to see how far I could get away from my router before completely losing signal. I walked a total of about of 30 yards from my router to the edge of my street and stopped every time the signal decreased down to one bar(which was between every 5 or 10 yards)... every time I thought the signal was about to drop out it would return back up to 3 bars after a moment of adjusting. Once I got to my furthest point it dropped out completely and then came back to 1 bar. When I came back inside where I previously had 2 bars I then had full signal throughout the house. I tested this a couple times and it seems that it only uses what it needs. If someone could do a similar experiment to confirm this isn't specific to my router set up I would appreciate it. I also did not notice any drop off in performance in speed from 1 bar to full signal while I was within 20 yards of my router, however, I didn't run a speed test, I just used my youtube app to load a video... I will run some speed test when I get home this evening to get a solid figure on the speed difference. This may not be a bug but a feature to conserve energy to increase battery life.

A good theory, but I am dropping wifi in some of my rooms. Switching to and fro like that doesn't save power
didnt people have poor performance with their wifi signal on ics? did broadcom leave everything the same of did they change/update drivers for our phones with jb.

Me too, I only need to move to the next room or so sometimes. The main problem for me is range. The range for me was better with 4.0.x.

ICS wifi performance on the GNex wasn't exactly perfect for me, but it was better than what I get with JB. My router at home is giving me an okay performance and range, but the routers I normally connect to at family and friends are giving me problems since I moved on to JB.
I believe JB does come with new drivers. At least I've read that it does, in other threads.

Wi-Fi has been fine for me, but only when using 2.4GHz—5GHz, on the other hand, is horribly broken. If you are using 5GHz, I recommend trying 2.4GHz instead—hopefully Google will have this sorted before the Galaxy Nexus II ships.
you may want to revert back to ICS to verify if the phone hardware is not a problem? otherwise for me I have used both... ICS and JB, and I don't find any difference..

5 Ghz was fine for me on ICS. It works on JB too, but the range...ugh.
I'm pretty sure it's not hardware related. It's definitely related to JB. It's not a 5 GHz problem either, that's what I use at home on my d-link. Family and friends have both 5 and 2.4 GHz. I'm sure it depends on the quality of the routers also but I didn't have any real range problems with any of them before JB.

2.4 is pretty weak for me too.
I looked at the calibration file from ICS to JB. I don't think the difference warrants the problems seen.
From ICS to JB, these are the changes:
# 2.4G ACR
rxgaintbl100=1
# 5GHz Starting Tx Gain Index
initxidx5g=96
The firmware on my wife's SPH-D710 was just upgraded to FH13. Based on my reading here, that upgrade included an improvement to the 3G modem. If that is true, this is a pretty sad phone - let me explain.
I downloaded Speedtest to my phone, a 2+ year old HTC EVO and here phone. I then ran Speedtest on both. (Actually, it was much harder than that. The GPS on her phone was simply not working, and Speedtest thought I was near Wichita, not southeast Michigan. Even after rebooting to get the GPS working, Speedtest still thought I was hundred of miles form here. Fortunately, the second-to-last server listed overlapped with the servers listed on my phone.)
To be clear: I did one phone then the next. I turned off the WiFi and help both phones in the same location.
HTC EVO: Ping - 192 ms, download - 2531 kbps, upload - 612 kbps
Samsung E4GT: Ping - 173 ms, download - 1789 kbps, upload - 520 kbps
The only difference is that my phone is rooted and I am running AdFree, but that certainly cannot account for the huge difference in performance.
I was actually quite pleased with my wife's phone until I a) ran headlong into the very poor GPS performance and b) saw the poor modem performance. I understand now why HTC phones cost more...

I thought it was common knowledge that the antennas on the e4gt were a little weaker than most, that seems to be a common trend in Sammy phones. If you want strong antennas I'd recommend Motorolla, however the software on their phones is ****. Motoblur, bleh. Regardless, Samsung still makes the best phones on the market and smother everything else out right now. The S2 helds its title until the S3 came out, nothing tops a Sammy phone but another Sammy I believe the smooth performance and top of the line GPU/CPU/screen is a good trade off.
My apologies if this sounded like a troll message. My wife's phone is clearly faster than mine with regard to processing speed. This is clearly noticeable when updating apps. My post was more a matter of disappointment - why it should clearly excel in some areas but seem to fall flat on others, especially given that it is a much newer device.
I just downloaded and installed Quadrant Standard on both phones. My perceptions were correct - the Samsung is MUCH faster than the EVO. So, again I ask/wonder, why the much slower 3G speed and poor GPS performance?

Your Samsung radio is not going to do better than the HTC radio, first and foremost you have to accept that. Then you can move on to trying out other modems in an attempt to improve signal and download/upload speeds.
There's a LONG list of them that have been released since back in February; you'll find the downloads for each in a stickied post in the development. It doesn't matter what kernel or ROM you are running, you can swap out modem builds at will. If one doesn't work, flash another but always make sure you update profile & PRL after each flash and before running any sort of speed tests.

Fh13 is battery improvements, if you update your prl that will help with download speeds. There are way to many variables for data speeds to get reliable info. 1.7 mbs download is damn good on 3g, I wish I got those speeds, I get .5 MBS if I'm lucky in Sacramento, ca. So anyway unless you have one of the lte phones that Sprint offers there is no better phone then the S2. And those phones are by no means leaps and bounds ahead of this one.

Thanks for the feedback. I am not an expert with regard to these matters and had assumed that a) the the newer phone would have a faster modem than the older one and b) the download speeds I recorded were not out of the ordinary. My expectations have been reset and I will enjoy her phone (when I can) for what it does well.
Those speed differences are small, I don't think you will notice. Also the faster processor will probably still load Web pages faster even with the slightly lower network speeds.

You have to understand something, network speeds tests are not exactly reliable measures. If you want comparable measurements, you have to run multiple tests on the 2 phones using the identical server at the same time. Then you average the tests. Otherwise, what you have is one data point, testing from a server at different times. So one point may have been when server was less loaded, or the network was less loaded. And even then, your original tests were close enough that you would not notice it, and to be "underwhelmed" just because of that is silly.
Root has absolutely nothing to do with data speeds. What accounted for the improvement is most likely a decreased load on the server or Sprint's network. I have seen much more variation than that on my own phone, simply by testing at different times of the day.
worrying about a 500 k difference on what appears to be pretty great 3g(remember, some sprint users get literally 100kbps) seems kinda bourgeois. how much faster do you need your porn to download?

Can anyone answer why TW roms report signal strength different from AOKP. (I don't mean 4G vs LTE or faster or slower speeds) When I have a TW rom installed, I can go virtually all day and have no reported signal loss, but if I have a AOKP (all source android for that matter) installed and I use the phone in the exact same place I have as much as 50% time without signal while the whole time I actually have signal as I use the phone. On the TW rom, signal almost never goes less than one bar but yet I can have no signal at all, but if it is like that for any amount of time then it will show no signal, but the AOKP will show no bars but still have signal and yet it still reports as no signal.(maybe there is a different scale for signal strength) This doesn't just on my phone, as I have 3 that I tested on with the same result. There is no problem with signal as I have said and the phone works fine during this time unless signal is lost totally. Some say TW has faster DATA and BETTER signal, I have never experienced either, both seen just as fast, which is why I wonder if sammy does it on purpose with some code or if AOKP has a smaller scale in which to report the strenght, hench my issue.

Did you actually check the signal dbm or just compared with the signal bars?
The signal bars are just images, therefor, you could set it to show 1 bar and actually have full signal db.
Compare their dbm and you'll see if there's actually a difference.
Another thing, keep in mind that every phone is built differently and one could have 3bars of signal while the other has 4bars, both phones running the exact same thing.

I've noticed the same. On TW I show 3 bars and on AOKP I show 1 bar. I believe it's just as you said the signal image reads off the dbm and AOKP might be set to show 1 bar off -108dbm with TW is set to show 3 bars

Aosp bases roms show signal more accurate then TW based OEM roms. We even found that att had changed some images early on to show more bars then what you were really getting.

Maybe for some folks it's just showing up like that.
But in my area, TW ROM's get me faster & better signal than ANY AOSP ROM. Hands down, flat freaking true. I've tested it with speedtest and speakeasy.
TW consistently gets me a better signal and about 20% faster download speed than any AOSP ROM since the ICS to the current 4.2.2 ROM's.
And not just on one phone either. I've had three S3 warranty phones (don't ask. lol). They all behaved the same way.
I've done "scientific" (as best as I can) tests and it's been very consistent like this. TW just gets a better signal I figure, which = faster download speed. I don't know how else to explain it.
I should also state that I'm on the edge of LTE area. AOSP ROM's usually give me about 1 or 2 bars and 5-12 mbps download speeds.
When I get closer to downtown, I get 30+ mbps download easily.
TW ROM's give me 12-18 mbps where AOSP struggles to reach 12 mbps. In the same exact location on my desk.
The speed is something else completely. That has nothing to do with the amount of bars shown.

Well to be honest it has to do with 2 things. One is how the software talks with the hardware. Second as I stated above. There have been times the carrier have flat out lied about how many bars you have. We found this when ripping the apks apart and there instead of being 0, 1, 2, 3, and 4 bars they removed the 0 and 1 bars and replaced them with the pngs for 2 bars.

Ya its weird, as long as it shows 1 bar, then it will not register signal loss, but soon as that bar disappears, but still with signal, it will register as loss of signal. When there is no signal there is a diff icon, so then and only then should it report as a loss..... I would like to fix but so far I have found nothing concrete, just options.
I think CM shows the true signal bars whereas TW shows the fake one.

A lot of times if it shows no bars yet you still have signal ie. Still able to text, call, surf Web it's because you're transitioning from 4G to H+ or whatever the transition maybe.

Well I have found some info, I am going to try this and based upon the results, I will post back so that anyone that wishes to modify their rom (if it works) will be able to do so.
The problem that I am referring to has nothing to go with the transition from 3g,h,h+, or lte for that matter. connection does not change, problem happens when you are in an area that has a lower signal, thus being able to USE the phone even though there are no bars.
