First go to this website: https://jawbone.com/devices
* If you're not already, you'll have to sign in
* In My Devices, click on BIG JAMBOX
* Follow the instructions to download and install the Jawbone_Updater-x.x.x.exe and click continue
* Then be redirected to the Voices and Tones page, which are the .dfu files
* Choose a voice you like and download it
* Now the speaker must be turned off and connected with the USB cable to the computer
* Double-click on the file (the Jawbone_Updater must NOT be running for this to work, you'll know if it is running if you see the "J" icon on the task bar (bottom right on Windows and I believe upper left on Mac) click it and then click "quit")
* After double-clicking the file click OK on a window after finding your speaker
* Now you just have to wait, the "J" icon will appear and become red and if you click on it you can see the percentage. This takes around 5 to 10 minutes.
DO NOT UNPLUG THE SPEAKER OR TURN OFF THE COMPUTER WHILE IT IS UPLOADING
