I WANT TO GO PSITA 4.50 DEX.

I'm actually on PSITA 4.50.

There is what i see on rebug toolbox:

Systeme firmware: 4.50
LV2 Kernel: CEX
Target: DEX

I cant access to the rebug toolbox CEX/DEX and Selector Functions cause im not on a REX firmware.
When im trying to install a downgrader like Rogero and Rewbug 3.55.4/REX firmware i got this error:

80029CCA Data corrupted (the .PUP file is grey)
Tried to install the downgrader with recovery and the same result...

I actually dont know what to do.. Anyone can help??

Thanks

Im not totally sure but ita is only a dex firmware and rebug toolbox doesnt work on ita use ps3ita manger

U CANT use rogero or Rebug, those are Cex downgraders, try using 3.55 dex downgeader

Exactly, rebug toolbox doesnt work.. But what should i do to go DEX ?

I downgraded my ps3 to 3.55 but i got the same message error (Data corrupted) when im trying to install the OFW 3.55.

Any idea?

ur trying to install 3.55 ofw cex. your on 3.55 dex

So what should i do now if i want to go REBUG 4.21 ??

your on 3.55 dex. install ps3ita 4.50
