cirus...thats the downgrade exploit, which changes some values and makes your psp *think* its a 1.00, but its still completely a 2.00
however, this gives you the option to run the 1.5 update file to *upgrade* your psp from the 1.00 version it thinks it is to 1.5, while it is really downgrading

and to all those having trouble playing homebrew on a 1.5, go to a "Playing Homebrew on a 1.5 PSP" FAQ, it will explain how to use the kxploit program (though i recommend getting Seipsp tools, PSPbrew, etc) to convert the eboots to run homebrew on a 1.5.
its not the downgrader that doesnt let you play it, you just need to know how to play homebrew on a 1.5

Of course you can.. you just need to use one of the Version changers (WAB or MHP) to change your version number back to 2.00

ok yes you 100% can re upgrade to version 2.0 after the downgrade i have now upgraded and downgraded 3 times with no problems. I do have one question though if i use the Version changer so i can play newer games like burnout on version 1.5 will i still be able to upgrade back to 2.0

Yes
for all new 1.50 users you will need to
Use (SeiPSPTool.exe) or (KXploit Tool )
To put youe emulators on your pSP If not you will get a "Game could not start" warning

Search this forum for the word (pre made emulators) and you can find them already made and ready to use in 1.50

Just use the wab changer and put your system at 2.00 and then delete the wab changer
After that you can play ANYTHING!
