mrdude has released a patch for the Pandora memory stick:
Thanks to all those involved in the pandora files - you guys know who you are! The pandora files are great but they have a slight bug in the restore.elf file in the kd folder, as they make a nand dump nicely but forget to call it a name so it can be restored without manually renaming the dump. This patcher patches the restore.elf file in the kd folder - so that restoring nand files can be done without having to rename the dump. Usage. Either copy the Restore.elf Patcher.exe to kd and exectute it from the pc, or copy your restore.elf file to the same folder as Restore.elf Patcher.exe and execute. This will produce a 'fixed' elf file which you should replace in the kd folder. Now you will be able to restore your nand dumps without messing around - or the need of a computer. This file also creates a backup so if you prefer the original file - you will have a backup. NOTE: Remember to remove the battery & reboot the psp after you patch the file.
