Dehash your console first. Then just update it like usual.

No Dongle needed.

Do you have to have the dongle to make this work ? or does it work regardless ?

Say if I wanna update from 3.55 rebug can I install over that or does it have to be from OFW 3.55 ?

1. Yes. If you want to use OFW again. Just install OFW over CFW.
2. Only use tested CFW. And follow proper instructions
3. Many~
