Sometimes it is necessary to hard reset a Plantronics Voyager 510 bluetooth headset if it stops responding to button presses or if you need to start pairing with another bluetooth device again. Below is an image describing the four buttons that can be pressed on the PLT-510 headset. These buttons can be pressed in various combinations to perform various tasks.
I have been running dd-wrt firmware on my Linksys wrt600n for awhile now however I have always had some issues. I had finally had the configuration to where the issues were minimal however it has never been perfect. I decided since it had been a couple months it was time to try a newer build from the site. I upgraded and things got a lot worse in terms of wireless on the 2.4 GHz channel so I did a ton of troubleshooting and read a lot of posts semi related to my problems with the 600N on the dd-wrt forum. During the reading I learned a lot about the proper way to flash the firmware and I wanted to share my findings here.

**NOTE** Hold the reset button in during this entire process
