Why don't you just update to CFW 6.39ME-v4 (Only if you have a PSP-1000 or PSP-2000)
For any other PSP, (except PSP-GO) upgrade to LCFW 6.39ME-v4

Download to CFW en LCFW 6.39ME-v4
- http://www.megaupload.com/?f=09UOVCZB (If you have previeous CFW installed)
- http://www.psp-hacks.com/file/2099 (Installer, CFW 6.39ME-v4 ((Only if you have a PSP-1000 or PSP-2000), no need for previous CFW, just straight from OFW6.39)
- http://www.psp-hacks.com/file/2100 (Installer, LCFW 6.39ME-v4 ((For any PSP model with exception for PSP-GO) no need for previous CFW, just straight from OFW6.39)
- You still need to find the official Sony PSP 6.39 firmware (OFW 6.39)

CFW 6.39ME-v4 is permanent CFW for PSP-1000/PSP-2000 only (Has an option to toggle between CFW en OFW on bootup (hold HOME while booting to start OFW))
LCFW 6.39ME-v4 is temporary for any PSP model with exception for PSP-GO

If you preffer PSP CFW PRO instead of ME:
