Error in restoring flash from server in packet tracer

[HarryModi98912]

I have used 2960 switch connected with 2 Desktops.

Then I took a backup of a switch flash "c2960-lanbase-mz.122.25.FX.bin" in TFTP Server.

Then I deleted the flash from switch.

the switch: mode opened.

Now, I don't know how to restore the flash from server.

Please advice.

Im not sure what you mean with restoring flash from server in packet tracer ?
just remove the switch and create a new one from your template

some model switch do not support image recovery using tftp, 

you can only restore the image using the serial console and XMODEM protocol.

look at this post that says the same

Unfortunately TFTP is not supported in rommon on the 2960 switch. You will have to use xmodem to load an IOS to the switch.

PT is just a Sim software based expected IOS behavior. it is not real thing; some commands and options do not work or aren't available. I think there should be a demo lab under Samples of PT under Menu.
