Thunai,
There is another option but it does not appear to be open to you. I have put the flash in the other router, in the second back and copied it across. You have 2x4M so cannot do this.
I would tend to think if you have copied runnignIOS from a working 2500 and still get the error, that there is a problem with the flash.
