I was just about to write & ask if going from v1 to v1.02 needed for the bootloader to be changed again.
I’ll find out the hard way in a few minutes & let you know… 
if you’ve gone straight from 0.9x to 1.02, you’ll need to start over- the instructions are all in the manual (the release notes should also point this out, though!), so you need to run a couple of other routines to repack the memory for the new o/s.
sorry if this is old news & doesn’t help…
