Rebug 3.55.3 / 4.21.1 PS3 CFW REX Editions, 999 Downgrader Out

[niwakun]

i don't want to sound supid but with this 999 downgrader ican update to any cfw or mfw without being worried right!!?

yes, the 9.99 Syscon Version will trick any CFW (4.21 or 4.30 Rogero for example) to be installed on the top on it without going through Recovery Menu

The installation will go like this:

If you're under 3.55 CFW/OFW, just update directly to 4.21.1REX

If you're under 4.xx CFW like Rogero or E3, you need to do this:

• Install 999 REX downgrader through XMB
• Once downgrader installed install REBUG toolbox and run it
• Go over the far right side, Enable QA (*this is required)
• Now install REX 3.55.3 over XMB
• Once REX 3.55.3 is installed, now install REX 4.21.1
• Job well done! Welcome to REX 4.21.1

If you under Debug Firmware, you need to convert back to CEX first and activate QA then turn on Debug Update, after that, install REX 4.21.1 under XMB.

is this CFW only for CEX users??

yes, only for CEX users, DEX converted consoles need to go back to CEX first.

any advice? im currently on 4.21 rogero i'm wanting to go to 4.21REX

will i be fine updating to the 999 downgrader, then to 4.21 rex? i tried to toggle QA flag but the button combo isnt working

when is it needed to enable QA flag?

[G Sus]

you should be fine with the .999 downgrader i only had those problems because i done a lot of wrong stuff going from 3.55 to 4.21 to 4.30 e3

and when trying the toggle QA combo make sure you remember to be on the network settings option

[zacksmith]

thanks, im gonna update to it shortly

has anyone tried the CEX2DEX function yet in this cfw?

[JOshISPoser]

when i start playing newer games now, i don't think i'll be too useful to this forum

i knew something like this would come up

[G Sus]

i noticed not all games work on rebug nfs most wanted worked fine from e3. but in rebug it wont even work from original game disk.

shame e3 had bugs in it cos its compatability was brilliant, looks like i'm gonna have to go looking for fixes for some games.

I'm on latest dongle CFW, and want to upgrade to REX CFW 4.21. Should I do it directly or have to do anything else before?

Thanks
