Update: Dark_AleX has shared with us Custom Firmware 3.30 OE-A For PSP today! Post all feedback in the Official PSP 3.30 OE-A And Compatibility thread! Forum thread, and from the ReadMe file:
Changelog:

- Updated from psp firmware 3.10 to 3.30
- Fixed a bug that could have caused inestability in 3.10 OE after recovering from sleep mode.
- Patched a protection that prevents the firmware to load higher firmware modules.

popsloader note: it won't work on 3.30 OE due to sony rearranging again the module list of pspbtcnf_pops. (thanks sony for destroying my backwards compatibility again ¬¬). I'll make a new version one of these days to support all current pops in 3.30 OE, 3.10 OE, and maybe 3.03 OE-C.
