(adsbygoogle = window.adsbygoogle || []).push({}); I have a fat 4.21 rebug ps3 I used ps3 ita manager 1.40 that supports rebug 4.21 but when I turned off my ps3. And turned it back on the screen is just blank nothing is popping up. I can go to factory mode but every time I reset me default settings or restore my ps3 the screen is still blank. Hopefully its not a brick. But if it is please someone tell me :unsure:

You need to upgrade you whole software so go onto Recovery mode and select system update it will ask you for an update download one thats higher or the same then the one your using the re install it

Hope this help you if not then its bricked and theres is ways to fix it Youtube it
