Recovering an Switch from bin prompt with empty flash

[Muhammed Adnan]

Dear Experts,

I have a 3560G switch with 48 ports. I had mistakenly reloaded with switch, without taking into consideration of fact that someone has already deleted the flash and saved the config. After reload, when the switch returned to bin prompt, I tried booting it only to get the surprise of flash as already empty:( 

 As the flash is now empty, is there any way out that I could be able to load the image onto Cisco flash? I need to bring this switch into working condition asap.

Would appreciate any help in this regards.

switch: dir flash:
Directory of flash:/

Dear ivaideanu , Inayath,

Thank you for your prompt responses. 

And yes, terminal emulator came in handy. From terminal emulator was able to transfer the image via console port to Switch's flash. After booting it came up fine perfectly. 

Thanks and Regards,

Adnan
