Same issue as
, I tried to dex->cex but as mention on the first post i should have to install the cfw before try to exit fsm.
I am trying to get factory service mode or downgrade with my hd2 and psfreedom without success.
I will search a cheap solution until next month and will buy an e3 flasher if no success.
Edit: Tried with my psp whith ps3jig no luck either, the PS3 power off to fast to initiate USB. Obsolutely need of flasher, I certainely buy the e3 flasher the next week until then i will try to passthrought without spend 100€.
