System updates won't install.

[jeffster1970]

My phone notifies me of system updates, and each time it downloads the update file, my phone boots, and I get the droid icon with a progress bar. It stops midstream, and show me what appears to be a failure icon (like a roadside caution sign). I have to remove my battery to reboot, and the install wasn't installed, because three days later, it will notify me that an update is available. My phone is rooted. Is there a solution?
