Did you try loading the 2.05 image using TFTP? That image is available from the Downloads section of the SHN web site. With both LEDs on solid it sounds like a hardware reset was done that put it in the mode where only a TFTP upload can recover. Also do you use a static IP and if so did you go back to DHCP before upgrading to 2.05. Send me an email address to firstname.lastname@example.org and I can send you an earlier image. Let me know what image level you want.
