I foolishly upgraded both of my PSPs to 3.71 M33, not reading that there was no 1.5 kernel. I knew I didn't need to upgrade and really shouldn't have since upgrading always equaled everything breaking (like changing from one Windows operating system to another).
Anyway, is there going to be a 1.5 kernel added (or the ability to downgrade) any time soon? 'Cause I REALLY want to go back to 3.52.
