I was on rogero 4.46 and i decided to change my system to DEX but after downgraded my ps3, i have problem : it is not on 3.55, it is on 4.21!! i tried with couple of firmwares but nothing i just got this message: Error 8002F157
QA flag was enabled
:confused:

any solution?

You get that error when doing what exactly?

when i am trying to update it !
or in the update screen

Are you still on Rogero 4.46? And what cfw are you trying to install?

I was on rogero 4.46 but i downgraded by rogero downgrader but it put me on 4.21 and the jailbreak works but i cannot install any firmware.
i trying to be on DEX 4.41

What firmware are you trying to install from the 4.XX downgrader? Because you can't just simply install a DEX firmware over a CEX one

I know that but i tried with many firmwares : 3.55 rebug, 4.46 rogero, and some firmwares
i just get this error 8002F157

Hmm, I'm not too sure why. Are you trying to install the firmware from the XMB?

from both XMB and Recovery mode
