I HAD similair problem:
https://supportforums.cisco.com/message/3853794#3853794
(Have ver 1.1)
Forgot password. Restored to v1.0.0.86 via telnet
Been playing around with telnet AND web based updates
Read somewhere else (Web-based ONLY works with IE)
(Tried Web-based and keep getting "Copy Failed/Undefined Error" and 0 Bytes transfered)
Know to upgrade "Boot" first, then "Software Image" THEN reboot
Tried telnet (not through web-based startup)
Can get to "lcli" (by Ctrl+Z twice)
Retyped Username and Password:
At "console#" tried typing "copy tftp:///srw2024_16_boot-101.rfb boot"
didn't work : "Must be valid URL or reserved keyword"
Where am I going wrong?
Stuck
