This is probably a stupid question, but I am having trouble understanding why we need to delete stub ios249 before cIOS install. Why will a patched ios36 not install over the stub? With a patched ios36 you can downgrade other ios, but when used with the cios installer- it fails. But if you use ios250 it will pass and install over the stub. Is it a limitation of the ios, or some hickup in the cIOS installer? Because I really think that uninstalling the stub should be unnecessary. Not looking for stupid comments, so do restrain yourself.
