Gaming Update Question

[SCPChop]

I have 5.00 M33 on my PSP and I wanted to update to M33-3 so that I'd be able to use the PSN Store. I'm a noob when it comes to using a hacked psp so I followed a guide dl'd it, copied it to the game folder in the psp folder and when i clicked network update it said I had the latest version already installed. Also if there is a newer version than 5.00-3 can you please link mme to a download along with instructions on how to download.

5.00-6?
If you've already got 5.00-3, just run this: http://www.dark-alex.org/forum/viewtopic.php?f=44&t=8158

It still says that I have the latest version but when I go to system information it only says 5.00 M33 not M33-6
