did you extract the "flasher for recovery folder" contents to your psp giving you the folder psp\game\recovery which contains 4 files (before usage) then get a 1.50 sce update eboot.pbp and rename to UPDATE.PBP and copy to the psp\game\recovery and then run it. these are the steps i used to downgrade to 1.50 and it was sucsessful.
p.s. any modding?
