Here's what happened:
The update path before this was 1.50->a bunch of other official fws->3.50->1.50 (Lumines exploit)->3.40 OE -> 3.51 M33 ->a few updates for it -> 3.52 M33.
When I tried loading DGEN, it didn't load. I tried restarting my PSP, but it semi-bricked. I then recovered to 3.52 M33, and then updated to 3.52 M33 update 2.
For some reason, now it won't save my recovery menu configuration. What can I do to fix it? (I don't want to go off any of the M33 versions, there are a few features I need) Thanks in advance.
EDIT: Also, whenever I go to the recovery menu and exit to the XMB, my background is removed.
