Sorry about the delay getting back. Was away for a minute.
It's not much different than the 1900 switch, get your console ready with the 9600 8N1, then unplug the swithc.
hold the mode button while you turn it back on,
when the light above port 1x goes out, let go, this will 'break' the start location and the password, follow the document below for guidance.

switch: flash_init
Switch: load_helper
Switch: dir flash:
If there is an image in the flash, it will show in the directory. If the image is totally wiped, you'll probably need to do an XMODEM transfer of a good image. First, though determine if there is an image still on the switch. You may see several other files under the directory (vlan.dat, boot_var, config.text, etc.). Don't worry about those.

If you're doing a password recovery on this switch:
switch: flash_init
switch: load_helper
switch: rename flash:config.text flash:config.old
switch: reset
This will prevent the existing configuration file from loading and put the switch in setup mode. You can cancel out of setup (ctrl+c) and get to privileged exec. From privileged mode, you can copy the config.old into the running configuration, change all the passwords and save to nvram. Then, delete the config.old.
