Re: Terrible Bluetooth sound quality since 4.0.4
Download
this zip file and extract it somewhere you can remember like the desktop.

Here is where you can find the download for the Radio:
Radios
The FA02 Radios worked best for me. For your convenience, I have included all the files you need in 1 package regardless of Operating System.
If you unlocked your bootloader, you will not loose any information. If you didn't, you will loose all of your information. There is probably a way to root the phone and install clockworkmod recovery, but it doesn't sound like thats what you want to do. If you unlocked your bootloader, proceed below:
Download clockworkmod recovery. We won't be installing it, just booting into it. Keep this .img file handy (I rename it to recovery.img. It makes the last steps easier).
(All Files included in zip folder I'm providing)
Download the Android SDK if you would like, all you need though is the adb and fastboot files for your operating system. For windows, its 4 files (adb.exe, AdbWinApi.dll, AdbWinUsbApi.dll, and fastboot). For linux/mac its adb and fastboot. Fastboot is not included with the sdk and either needs to be compiled or you can download it from the internet.
Make sure you have drivers installed (windows only). If the commands later don't work, its likely you don't have the appropriate drivers. I included them (you're welcome).
Unzip the folder I'm providing you. Place the contents somewhere you can easily navigate to. Desktop is a popular choice regardless of OS. The next bit is instructions specific to your OS.
Windows:
You need to get the address of where you saved the folder... specifically the Windows folder inside. Below is an example, but if you are having trouble, you can right-click the folder in the Top navigation bar and select copy address or copy address as text (both work the same for this).
Open start and type in cmd which should open a command prompt window. Type the following 1 line at a time:
Code:
cd C:\Users\YOUR_NAME\Desktop\AdbFastboot\Windows
adb push 4.0.4Radios.zip /sdcard/
adb reboot bootloader
fastboot boot recovery.img
Your phone (if the bootloader is unlocked) will boot into clockworkmod recovery where you can then select:
install zip from sdcard --> choose zip from sdcard --> 4.0.4Radios --> reboot
You're done! You will not be able to update the device as the radios will be on the incorrect version. For future updates (ie Jelly Bean) you must flash back to the crappy radio first, then accept the update. All your files and profiles will remain unharmed in the entire process. You can get a copy of your current radio in the post above that I linked. You will need to repeat the same process above to flash the current radio software.
Mac/Linux:
Open up terminal. Its in your Utilities folder in Mac. You can Drag and drop the folder into terminal if you cannot figure out its address. Follow the next Steps:
Code:
cd ~/Desktop/AdbFastboot/MacLinux
./adb push 4.0.4Radios.zip /sdcard/
./adb reboot bootloader
./fastboot boot recovery.img
Your phone (if the bootloader is unlocked) will boot into clockworkmod recovery where you can then select:
install zip from sdcard --> choose zip from sdcard --> 4.0.4Radios --> reboot
You're done! You will not be able to update the device as the radios will be on the incorrect version. For future updates (ie Jelly Bean) you must flash back to the crappy radio first, then accept the update. All your files and profiles will remain unharmed in the entire process.
