Use the 1.50 Recovery Winstaller. Once that's installed, go into Recovery Mode (boot holding R-Trigger) and go to Recover. You will now be flashed back to 1.50. Remember to format the memory stick in Windows and then in the XMB, or all the folders will remain when you upgrade to 3.40OE-A. You're going to want a fresh copy and to prevent any possible problems.
