Unsuccesful installation firmware 2.30 to 2.50

Installation process seems succesful, but it isn't. Eventually there is still the old firmware (2.30) in my Forerunner 405.span.jajahWrapper { font-size:1em; color:#B11196; text-decoration:underline; } a.jajahLink { color:#000000; text-decoration:none; } span.jajahInLink:hover { background-color:#B11196; } span.jajahWrapper { font-size:1em; color:#B11196; text-decoration:underline; } a.jajahLink { color:#000000; text-decoration:none; } span.jajahInLink:hover { background-color:#B11196; }

I had a similar problem. After a few attempts I was able to update the firmware to version 2.50. This is what I did:
1. Close the ANT Agent application by right clicking on the icon next to the clock and selecting Exit.
2. Reset the Forerunner 405. Mine was frozen on the LOADER screen. I held both buttons for a few seconds and released them when the rebooting process started.
3. Open the ANT Agent application and then go to the GARMIN webpage to download the update. Make sure you have the latest ANT Agent version.
4. The update process started and ended in about 2 minutes. Then it started again and lasted anothe 9 minutes.
5. The watch reboots with the new firmware version but retains all data amd customs settings.
Good luck.

Power light is blinking with an on-unit code "W OPE"

Apparently the firmware installation process was interrupted. Try re-installing it by powering off your SCBT330, the connect an Ethernet cord from your router to the back of the SCBT330 - do not use a wireless dongle for this procedure. Power on your SCBT330 and the firmware installation should pick up where it left off at. Please be patient, this process can take up to 10 minutes to complete.

Cannot install operating system on my pc

Hi Normally it will restart on its own but will boot from the hard drive this time and will continue the process of installation. However, it will still require that you leave the cd in. Please let me know if this solution helps. Thanks, Lolita
