I have done some looking and I do not find any indication of what would cause the flash in 2621XM to be read only. But that does seem to be the case with your router. I believe that I had a similar problem a while back (different platform but its flash was marked read only). If my memory is correct I resolved the issue by doing a format of the flash, which erased all content on the flash, but produced a flash that I could write to. So I suggest that you try to format this flash and see if the result allows you to put a different IOS onto the flash.
