Firmware upgrade - Error

[gabsnet]

Hi Guys, 

See if you can help me.

I am trying to transfer the firmware from my desktop to my Switch Cisco 2960S. I can reach, I can ping, it starts to transfer but I got that error in the end (see attached)

Its been used the TFTPD32, SW CISCO 2960S, both are in the same network

What is the network layout of the switch to the TFTP server?

Hi @Leo Laohoo 
I am using vlan 100 to connect my SW in the network, port f0/24. I can reach everything here,

I am connect through a console cable

[gabsnet]

Another fact.
I am able to export files. But I can't import to my Switch

[Leo Laohoo]

Console access means you are physically next to the switch. 

Transfer the IOS into a USB flash drive.

Unfortunately this model doesn't has a UBS port. 

[Leo Laohoo]

All 2960S and 2960X/XR have a USB port.  

If this switch does not have a USB port then it is not a 2960S.  If this is not a 2960S and the switch is being forced to load an IOS of a different model, the switch will boot into ROMMON.

in addition to Leo's remark
i see a lot of "!OOO!O!OOOO" in your output, on a reliable network it would show "!!!!!!!!!!!!!!!!!"
which means there is something seriously going wrong in the connection

[gabsnet]

Yeah, I know that it should show "!!!!!!!"
But I have no idea how to fix this. It's weird because I can export from my Switch, but I can't import to my Switch.

Should I change to vlan1 ? currently I am using vlan100

[pieterh]

>>> Should I change to vlan1 ? currently I am using vlan100 <<<
that depends,
- which vlan is directly connected to your tftp server?
- which vlan has an ip-address ?
   if the switch only has an ip-address in vlan 100 than stick to vlan100
- which vlan have you configured as source-interface vor tftp

- check speed and duplex of the ports involved in the file transfer
-  try another cable
- check routing from and to the switch does not take different paths

[gabsnet]

Sorry, this is a WS-C2960-24TC-S

[Leo Laohoo]

If the switch is a plain 2960, the IOS BIN file is for a 2960S.  If you persist, the 2960 switch will attempt to boot an IOS version meant for a 2960S.  Because the IOS is not compatible, the switch will boot into ROMMON.

[gabsnet]

But I am not trying to boot now, I was just trying to transfer from my PC to the Switch (I won't transfer this wrong file, I will get the proper one.).

I tried some different ways, but didn't work,
Still happening this weird problem.

Have you install TFTP on OS , then input Ip address of cisco , use tftp localhost\flash:[binfile] [remote host machine IP]  to do imge file uplaod and transfer
