PS3 DEX 2 CEX: The Easy Way Without Bricking Guide

[fox460]

Brenza , One man from Russia got a trouble, he on a qa_flag launching stage. He tried 3 times but still no 3 beeps. How to avoid this issue? Thanks

i think you should not install MM 4.10.0, you should install MM 4.10.0 below, just pick/install one of MM 4.4.4 till MM 4.10.0. and flash it with that MM.

Thaks will try ! and post result here

edit: just pick/install one of MM 4.4.4 till MM 4.9.0. and flash it with that MM.

Good luck. I am very interested to know

CECHK08 was converted successfully. My respects to the author. DEX trip was harsh, guys.

Thank You fine sir followed your guide without a hitch worked flawlessly back to cex 3.55, thank you very much.

[Brenza]

You are welcome, I'm really happy!

when qa flag homebrew freeze and force you to restart the ps3 preceed even if you don't hear any beep if the ps3 restarts to xmb after you set the retail target id it's qa flagged! (without qa it would brick )

Works for me, thanks Brenza.

Converted back to OFW 3.55 CEX, upgraded to Rebug and redexed. You never know when you want to downgrade easily

i found the rebug dex switch a little scarey, what did you think portalcake

and do you know if when in dex mode can i just use the dex downgrade feature with the 3.55 downgrade pup stored on HD to get back to 3.55. i doubt that you could then use it to go back to 4.25rex because otherwise we wouldn't have had to convert back to cex to install the rex pup in the first place.

[Brenza]

well... REX cfw is a retail (cex) firmware that optionally can load a debug (dex) coreos so you need to be on CEX to install it

Rebug toolbox conversion works only if you qa flagged your ps3 while using the CEX targetid, if you qa flag while using a dex targetid and you try to go back to cex you 100% brick

NB: If their qa flag tokenator read the idps from EID5 there's no problem, if it reads from EID0 you brick
