Restoring C2960-S

[Denson]

So i've recently bought a CS-2960-S and tried upgrading it.

Since uploading the lastest firmware using TFTP kept failing near the end i've decided to delete the running firmware folder (c2960-lanlitek9-mz.122-50.SE4) from the flash.

After that uploading the new firmware (c2960s-universalk9-mz.152-2.E9.bin) was a success.

when i change the boot path (boot system flash:c2960s-universalk9-mz.152-2.E9.bin), save (write mem) and reload the switch i get the message 'error loading 'flash:/c2960s-universalk9-mz.152-2.E9.bin". I did check md5 hash before rebooting, but now seem stuck at the boot.

Smart as i am i haven't made a backup from the previous firmware, and for some reason this version is no longer offered on the cisco site.

I have also tried restoring using the mode button, but the SYST led keeps flashing.

any idea's?

@Denson hello,

you can restore it using xmodem to transfer your IOS from console. 

extraputty to use xmodem: http://www.extraputty.com/

here is a exemple to how do it: https://community.cisco.com/t5/networking-blogs/loading-an-ios-on-a-switch-via-xmodem/ba-p/3103557

Best regards,

[Denson]

Thank you for your advice. It seems i'm getting stuck at booting from the new image. Uploading the image using xmodem worked just fine. The following message is now for over 30 minutes in my terminal:

'File "flash:/c2960s-universalk9-mz.122-55.SE13.bin" uncompressed and installed, entry point: 0x3000

Hello,

when you finish transfer ios from xmodem, your IOS start well? Because you can use this image: https://software.cisco.com/download/home/279963375/type/280805680/release/12.2.55-SE12

Check ios before install: https://tools.cisco.com/security/center/resources/ios_image_verification.html

Uploading firmware was succesfull, booting from firmware results in following message:

Checking for Bootloader upgrade.. not needed
Error: *** Unsupported platforms ***
Error: hardware not supported by firmware.
Try loading newer software instead.
System Resetting..

For what it's worth, the back of the switch has the following model listed: WS-C2960-24-S-V05

The current boot loader version:

C2960 Boot Loader (C2960-HBOOT-M) Version 12.2(53r)SEY3, RELEASE SOFTWARE (fc1)

So you have a "plain" 2960 but you're trying to force the appliance to boot a firmware meant for a 2960S.

hahaha.. really, i missing it ^^ thanks

[Denson]

just tried booting from: c2960-lanbasek9-mz.122-55.SE.bin

same message: 

Checking for Bootloader upgrade.. not needed
Error: *** Unsupported platforms ***
Error: hardware not supported by firmware.
Try loading newer software instead.
System Resetting..

@Denson hello,

This is the IOS that you need. use it.

[Leo Laohoo]

Don't let us guess.
What is the EXACT model of the switch?

[Jaderson Pessoa]

i think that is it:
"Since uploading the lastest firmware using TFTP kept failing near the end i've decided to delete the running firmware folder (c2960-lanlitek9-mz.122-50.SE4) from the flash."

This IOS file is not compatible with a 2960S.  The switch will refuse to load it. 

2960S firmware can be found HERE.
