PS3 need help with cfw swap

[twitchybear]

hi guys I currently have my ps3 on
Rebug 4.82.2 D-rex in DEX mode with cobra and qa flag enabled and webman enabled and I don't wanna upgrade to 4.84 rebug yet, my whole question is i wanna try out
ps3ITA 4.75 cfw. ik it's a dumb thing to switch when it's outdated but i just wanna see what it was like. how would i go about getting to 4.75 ps3ita cfw from 4.82.2 rebug d-rex in DEX mode and could u tell me what I need pkg wise for ps3ita when i get it installed such as ccapi and stuff.
I do have a usb and laptop,
any help would be appreciated and thanks

so I don't need to downgrade to 3.55 first?
cause i heard somebody say i needed to downgrade back to 3.55 first from rebug
and why switch to cex in rebug toolbox?
isn't ps3ita dex only and can be only installed over dex?
or it doesn't matter cause I'm on D-Rex?
and since I'm on 4.82! wouldn't installing 4.75 ita cfw brick it cause it's not a 4.82 cfw or higher and cause i didn't downgrade to 3.55 first?
sorry for so many questions lol..JUST don't wanna brick! and tnx for the help so far
