Thread: Etrex 20 and 30 : an easy way to get into pre-boot

I used the method numerous times and the etrex 30 was easily recognized by Updater.exe. Too is safer because it is not necessary to keep any button pressed during the process and were not dependent of synchronization to the pre-boot.


Press and hold the joystick bar of the etrex for 10 seconds while turning ON the GPS.
Should then appear the white Diagnostic screen. Release the joystick, load the .rgn file that the GPS will be recognized by Updater.exe. Just give OK and wait for the installation of firmware.


If you can not enter the Diagnostic Page use the traditional method.
