Repetitive updates to the same OS version

[spurdog46]

I frequently get updates pushed to my Xoom Wifi device (which is running 4.0.3) that say they are for android 4.0.4, but when I check under Settings/About Tablet after the update the device indicates that it is still running Android 4.0.3. Since that update doesn't seem to work properly, will I be able to get the 4.1.1 update? Any ideas about how to fix this?
