read this again:
remember that you dumped 1.50 eboot's ipl to your memory stick then wrote it to the memory stick, meaning:Quote:
NOTES AND RESTRICTIONS
- The firmware in the Memory Stick is not a full 1.50, but a minimal
subset. Therefore, not all applications (such as flashers, or
recovery apps) will load.
the subset is used to load the Pandora Menu from the memory stick and Flash the 1.50 eboot to the PSP, meaning its flashing full 1.50 version.
