Every time phone reboots all changes are lost

[kynrek]

I have a Droid 2 running 2.3.3 and if I install or remove an app and reboot all changes made are reverted to the way the phone was las time I rebooted it. I keep getting SBF error on group #31 and all root methods I have tried have failed. It almost seems like I dont have access to make permanent changes to the droid's filesystem.
