Upgrade to 3.52

Hello this is my first hacked PSP and I'm stuck. Using the files from http://www.dcemu.co.uk/vbulletin/showthread.php?t=68592 I was able to update to 3.51 m33 after pandoraizing my psp(1000).When ever I try to update further it tells me I need 3.52 but there is no download like that. I tryed to find it out by reading the threads but all i found was something about running the 3.51 update with the 3.52 eboot. Can some one point me in the right direction?

why 3.52? i use 5.00m33 so i know its not the most recent version. just redo the pandora and do 5.00 (or newer, idk, but i know 5.00 works well)

All the installs for 5.00 I could Find Required 3.52 to be able to run
