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.

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...

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.

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.
