I need to make sure that the System mode is changed to Rebug and the Toggle QA Flag is enabled, right?
I want to downgrade because of CCAPI.
Yes it possibile
First Download 3.55 DEX CFW (Downgrader):

Make a new folder on your USB name it PS3, then make a new folder inside the PS3 folder, name it UPDATE
Drag 3.55 DEX Downgrader inside the UPDATE folder that is on your USB
Rename the file 3.55 DEX Downgrader to PS3UPDAT.PUP
Plug USB to right slot of the PS3 then go to system update, update via storage hit x
You will see 3.55 pop up the screen then hit x, follow the simple instructions on the screen
