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.
can you launch game's from an app home kind of thing as my bd drive broken and would like to install this but don't want to install and not be able to launch any of my games home. someone can help me?

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
thanks, im gonna update to it shortly
has anyone tried the CEX2DEX function yet in this cfw?
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

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?
