Hello @Nishan Thevathason,

I recommend you make gradual updates to the version you want.

Sometimes, jumping to the last update brings problems.

Did you try to add flash:c2960x-universalk9-mz.152-6.E2.bin?

You should specify also flash: before the IOS name.

The error message is because the boot variable string syntax is incorrect.  

Post the complete output to the following commands: 

1.  sh bootv; and

2.  dir
