  1. A hard reset erases ALL of your data. A soft reset does not, only system files are overwritten (FP OS or Google Apps e.g.)
  2. A downgrade is as far as I know a soft reset and thus should not erase any personal data. A backup is always recommended. Here is how to install OS version 1.6 manually.

I’d like to hear another opinion on this though. Can you, @Chris_R, confirm the above?
