    You won't reflash it because you can't buy a serial cable :s...
    Serial cables are sold for a pittance, and they are relatively easy to get in an IT store or online.

    First, you should get a new firmware for the switch. I used version 3.23 (ls3k3_23.slx) (see 3Com Software Library).
    Furthermore you need a null-modem-cable and a program like minicom to communicate with the switch trough the serial line and you need a TFTP-Server which can be reached by the switch (for windoze you could use 3Coms 3CServer). You need it to serve the firmware for the switch.
    How to do it
    1. connect the null-modem-cable, connect to switch (Login screen should appear)
    2. push reset button shortly
    3. wait about 3 seconds
    4. Push reset button again and hold it down for about 1/2 to 1 second. Software-update-prompt should appear on the console.
    5. Enter data and start firmware-update, e.g.: S 192.168.0.2
      F ls3k3_23.slx
      B
      After a successful update the switch reboot automatically.
    6. Log in as 3comsco with password RIP000 (3 zeros) using the serial line.
    7. Enter the password-field, push Right-arrow 6 times, push Backspace 6 times.
    8. Enter admin as username, press ENTER.
    9. Done :)) Now you can select the menu-item INITIALIZE to reset the switch to factory defaults. You can use the standard-password-combinations now!
    I'm not sure wheater points 6-7 are really needed or not, but it works with them.
    Note: Don't forget to configure the switch securely again!
