Hey player....I got my flasher installed no problem but im having some issues getting the dual boot to work...The flasher use to be in another ps3 at one point and the onboard nor was already flashed with 3.55 cfw...
I was following the dual boot guide but when it says to flip the switch to cfw, the ps3 would not boot.
I left the ps3 on ofw and downgraded it and the installed ofw 3.55 and the upgraded it 4.21 cfw. Worked good....
This is where my confusion starts...I wanna flash the onboard nor with this cfw...I flipped the proper switches and hit start..Everything went well i thought..
I powered down the ps3, flipped it back to ofw and swapped the drive....It would not boot. I could not get it to boot no matter what i did...swithing the dives back, flippin the switch to cfw again...nothing seemed to work. I then followed your guide and got it back to where i was.... all switches are down, cfw 4.21 is installed and i dont know which is the right way to set up the dual boot from here.
can you give me a hand?
