e3 flasher downgrade question ofw 4.31 "PS3JIG"

[EmBoLa.be]

Can i use my cfw psp instead of a downgrade dongle on ofw 4.31?
ive been out the scene for more then a year now, a lot has happend since.
because i am worried i cant get out factory mode unless i flash the nor with the 4.31 ofw backup, then its pointles to use a psp. or do i not need to worry about it.
i cant find any tutorial or help for 3.56+ fw's. and i know how to use the search function and how to use google :-)
thx

A ps3 on 3.56+ ofw can not exit factory service mode with any downgrade dongle/dongle-like device.
