OKay upon reading this I want to update but I have a couple of questions I want to ask before I do.

1. If I do upgrade to DEX, will I be able to downgrade back to 3.55 CFW?
2. Does DEX let you play games from a external HD with Multiman, like 3.55 cfw does?

Not very likely if at all for the time being.

1. Yes you can > read here: 4.21 dex leaked
2. No you can't, as mM won't allow you to do so due to the official firmware's limitations.

I have a feeling Sony will remove the downgrade feature in the next version.

No, You must first covert your console to DEX first then you will be able to install debug firmware like this one.

Hey guys,
i have a big question [a noob one to be honest]...
I have a PS3 with OFW 4.21 installed, can i install 4.21DEX and then downgrade to 3.55 OFW?! After that can i install CFW 3.55 ?! I saw with DEX you can downgrade but i didnt understand how far you can downgrade, or if it only lets you downgrade to DEX FW's... Thanks!

First you would have to downgrade to 3.55 with a hardware flasher, then do the conversion to DEX. After you convert you can install the 4.21 DEX firmware. Only after you've done that can you downgrade at will and convert back and forth from CEX to DEX and back again

Hello all
Just finished converting cex to dex. Using 4.21fw. Now I'm playing an original game, and it askes to download the update..I do and I get an error. I can play the game without the update. Do I have to convert the updates for dex?

i think so. i'm pretty sure they've converted a lot of updates

DEX consoles don't necessarily need to play CEX disks. So instead of removing the downgrade capability, they can instead remove CEX public keys (keys needed to read and process eboots for booting contents) from the firmware, effectively killing any interest pirates might have in DEX consoles.

DEX4.21
->Enable core-dump
->Start Game via Target Manager or USB-BD-EMU
->Create an intentional Crash
->Grab decrypted EBOOT from dump
->Encrypt, sign & package for 3.55
->profit?

Cheers
