The only way you can trasfer the image is by using xmodem.

Hello,

you might not have a valid image in Flash for the router to boot from, check the content of your flash with the 'dir flash' command, if there is an image in there, try to boot manually with the 'boot' command. If there is no valid image in flash, use xmodem to download it onto your flash...

HTH,

thks guys, the Xmodem way works fine ...
