Hi,

You need to do a password recovery on the switch.

Follow this link step-by-step:

Here's what i have...followed your link!
Boot Sector Filesystem (bs) installed, fsid: 2
Base ethernet MAC Address: 00:1d:e6:42:60:80
Xmodem file system is available.
The password-recovery mechanism is enabled.

The system has been interrupted prior to initializing the
flash filesystem.  The following commands will initialize
the flash filesystem, and finish loading the operating
system software:

    flash_init
    boot


switch: flash_init
Initializing Flash...
flashfs[0]: 6 files, 1 directories
flashfs[0]: 0 orphaned files, 0 orphaned directories
flashfs[0]: Total bytes: 15998976
flashfs[0]: Bytes used: 12792832
flashfs[0]: Bytes available: 3206144
flashfs[0]: flashfs fsck took 10 seconds.
...done Initializing Flash.

switch: load_helper
Unknown cmd: load_helper

switch:

==========================

I tried several attempts. If I choose boot I get stuck in the loop. I do get the switch: prompt . But that's all. Never saves the flash_init. Get the same message everytime I boot.

Jezz the one thing I could always do, if nothing else; is reset the switch!

Couple of things I tried

If I try enable I get

unknown cmd: enable.

Copy start run 

start: no such device.

This switch may have been in a stack. Would that make difference?

Thank you

Figuring its a image issue
I am trying to recover the Cisco IOS Image

switch: format flash:

switch: set BAUD 115200

close putty and reset baud rate

switch: copy xmodem: flash:c3560-ipservicesk9-mz.122-53.SE.bin

Now i getting:  xmodem: : I/O error
Tried a slower baud rate nada. Guess my next step is to setup a TFTP server
and try that.
LOL
Man did I brick this or what!

Hello Reza
Followed your link!
Here's what I have when I boot

Boot Sector Filesystem (bs) installed, fsid: 2
Base ethernet MAC Address: 00:1d:e6:42:60:80
Xmodem file system is available.
The password-recovery mechanism is enabled.

The system has been interrupted prior to initializing the
flash filesystem. The following commands will initialize
the flash filesystem, and finish loading the operating
system software:

flash_init
boot

So:

switch: flash_init
Initializing Flash...
flashfs[0]: 6 files, 1 directories
flashfs[0]: 0 orphaned files, 0 orphaned directories
flashfs[0]: Total bytes: 15998976
flashfs[0]: Bytes used: 12792832
flashfs[0]: Bytes available: 3206144
flashfs[0]: flashfs fsck took 10 seconds.
...done Initializing Flash.

switch: load_helper
Unknown cmd: load_helper

switch:

==========================

I tried several attempts. If I choose "boot" I get stuck in the loop. I do get the switch: prompt . But that's all. Never saves the flash_init. Get the same message every time I boot.

The password-recovery mechanism is enabled.
