I shrank 5.0 before installing it and I came up with the same erros. It usually popped up for me when the phone rebooted after install. I foundthat I have more memory and a stabler OS with out shrinking. Also when loading the OS, back up 3rd party apps and load on the phone after OS installation is complete. I ran into a few erros trying to load 5.0 with some of my 3rd party apps on the same install.
