if you are concerned that things are not quite "right" you could:
-boot to fastboot
-launch amon(not install)
-make a backup
-boot to bootloader when your finished
-select "factory data reset" or "clear storage" in the hboot menu
after the phone reboots and settlles,you could launch amon again and restore your backup.
but,i think i have seen that error every time i have booted to the stock recovery as well.
