(adsbygoogle = window.adsbygoogle || []).push({}); My PS3 is on DEX 3.55 Downgrader and it won't let my Toggle QA, or anything. I want to go onto kmeaw 3.55 so I can change firmware but nothing works... Also my LV2 Kernal is on CEX and the rest is in DEX... is there anyone else out there that knows how to fix this?! It would be greatly appreciated.

Go to debug settings find system update debug and enable it then Load multiman go to file manager ps3 root dev_hdd0 make folder on your hard drive called updater inside that folder make another one called 01 put your rebug d_rex ps3updat.pup file there then go to system update and install from hard drive hope that helps

you could always just upgrade to ps3 ita 4.21 dex cfw I know it's not rebug but still has all you need.

Sorry my PS3 won't even let me update. The update is always greyed out and won't let me update because it says its courrpted, and I have tried in recovery mode too and it doesn't find the update. And do I need to install kmeaw 3.55 before changing to a different firmware?

And nath02 my ps3 doesn't display System Update Debug?
