[BahumatLord]

To help people with their questions about CEX 2 DEX conversion, please check here for answers first. If you don't see it, post your questions below and this post will be updated as soon as possible. Fellow members that can answer the questions please do and your answer will be added too.

Q: Can I play 3.6+ games?
A: Yes. You can play any original retail disc up to 4.20

Q: Can I play backups of 3.6+ games?
A: Sort of. You need PS3GEN and a usb hard drive split into 4 partitions. 45 gigs per partition. One game per partition... Read on

Q: Can I have more then 4 partitions on one hard drive to allow for more then 4 games?
A: Yes. After formatting the USB Emulator HDD you can use a hex editor to change the amount of partitions and the usable size. Tut here: http://psx-scene.com/forums/content/...ncreased-2497/

Q: If I go to 4.11 DEX can I play my previous backups like I do now?
A: No. You can play any retail disc that exists today. If you want to play your backups you would install 3.55 DEX with Peek/Poke support

Q: If I update to 4.11 DEX or 4.20 DEX will I be able to downgrade back to 3.55?
A: Yes. Just install this firmware http://www.ps3devwiki.com/files/firm...r/PS3UPDAT.PUP

Q: What if something better comes out? Am I stuck on DEX?
A: You're not stuck. Follow these instructions to go back to a normal retail PS3

To get back to CEX/CFW from DEX:
* If you're on 3.56 or higher DEX install 3.55DEX_downgrader firmware: http://www.ps3devwiki.com/files/firm...r/PS3UPDAT.PUP
* You can also use Rogero's 3.55DEX_DOWNGRADER_PEEK_POKE firmware (not tested): R-3.55-DEX-DG-C_F_W-PeekPoke.PUP
*Install multiMAN regular (for CEX/CFW) (otherwise you will get "Error accessing device! Install proper firmware!" error
* Use your original NOR dump (my-original-cex.NORBIN) and rename it to (my-original-cex.EID0.NORBIN) or in case of NAND: Use your original NAND dump (my-original-cex.NANDBIN) and rename it to (my-original-cex.EID0.NANDBIN)
* Double click on your CEX flash file in mmOS (i.e. /dev_usb000/my-original-cex.EID0.NORBIN or /dev_usb000/my-original-cex.EID0.NANDBIN)
* Quit multiMAN and from XMB press+hold {PS} button -> Turn-off the system, then start it again * Install OFW/CFW 3.55 from XMB

Q: Why did my BluRay player stop working?
A: After downgrading to 3.55 DEX from a higher firmware you may need to remarry your BluRay drive

Q: Will I be able to go on PSN with 4.21 DEX?
A: No. Another patch will be needed to re-enable PSN access. The conversion process breaks PSN access

Q: I want to downgrade from 4.21 DEX to 3.55 DEX but I get an error, am I stuck?
A: No, this problem can be fixed by changing Boot Mode in *Debug settings" to "System Software Mode"

Q: I get a trophy error when trying to load a 3.60+ game from the BD-Emulator hdd, is there a fix?
A: Kind of, you may be able to fix it by deleting the trophy data from xmb but if that doesn't fix it or there's no trophy data then build the game in ps3gen WITHOUT adding trophy data and NOT ticking trophy.

Q: I'm getting a 80010009 error when trying to run a BD-Emulator, what happened?
A: There are a couple of games that don't work on DEX consoles yet, if you know it's supposed to work you may have forgotten to install the fixed update or the update is for the wrong region.
If it still errors go to Debug Settings and change Boot Mode to Release mode.

Q: I was told I could play any 3.55 compatible game discless on DEX, how?
A: To load 3.55 compatible backups that are not discless change Debug settings to USB/HDD, load a game(not necessarily the game you want to play) with ps3gen and put the hdd in the right most usb port, be running a 3.55 DEX MFW, choose the game you want to play in Multiman and load it from the disc icon in the XMB

This is just a start. More to come

USER CONCERNS - Please read. There is always a risk involved in flashing your console. The posts below are valid concerns and I try to answer them as best as I can and give a working solution. My response has been tested on my slim PS3 several times, but it is up to you if you decide to try it or not. Nobody can be held responsible if you do something wrong and end up with a brick.

rimi -

Q: What if something better comes out? Am I stuck on DEX?
A: You're not stuck. Follow these instructions to go back to a normal retail PS3

Correction and this must be everyone know before they do it:

A: Yes and No.

Yes - If you have a flasher with good NAND/NOR flash backup when you were still in CEX and unmodded eEID
No - If you use a full software method, specially if you are going back to DEX - CEX. You will be getting a 100% brick for good. There a workaround on it but it's hell a lot of work to do it (not just a simple mm flash the cex method), specially restoring its capabilities like Blu-ray player and such.

My response - You don't need a flasher. Those instructions tell you how to reflash through multiMAN with date code 20120722. I've gone back and forth several times. deank disabled full flash writing and only allows you to write the EID0 section. Full flash writing even with a hardware flasher is risky and may have to be attempted several times before success

bahumat i think you should correct something,recently digitaloverdose told me that 3.60+ backups can also work via burned discs replacing the need for the external usb drive and PS3GEN,but you still need retail updates converted to debug.

[BahumatLord]

Yeah, i saw something about that, but it only works on a limited number of burners and with certain discs. I think I have a complete known working drive list and will add it after I do some fact checking. I don't have a BluRay burner so I can't test it myself

[futuretime23]

i thought you could just burn a backup into a dvd and that's it(i recall DX:HR being able to be a dvd5 game)

[BahumatLord]

I'm not sure. I know there's an option for it, but don't know if it will play. Have you tested it or have a link to look at?

[futuretime23]

well,i think you have to use ps3gen(correction myself from what i've stated earlier),but im first going to convert my ps3 slim which is NOR IIRC,but from what i've looked at a few tutorials,it seems that you can use ps3gen and then burn the disc to either a dvd or a bd(even though it wasnt tested with ps3gen,i also recall back from the few people that had dex before the cex2dex craze began that backups had to be run on disc yes or yes),so i suppose if it works,im sticking to games up to dvd 9 size,as my burner can only burn up to dvd 9,no bluray discs.

[RandomUser]

I do not know if this is correct or not, but you might want to add a correct version of this to your FAQ

Q: Can I have more then 4 partitions on one hard drive to allow for more then 4 games?
A: No, only 4 partition per hard drive is supported to play games.

Again I do not know if this is correct or not, so I would like to know if this is true or not.

[BahumatLord]

@RandomUser - you got it right. I added it to the first post. Thanks for the help

[wartutor]

BahumatLord if it's possible u may want to add aldostools tutorial on how to install dex on the first post...also i've read something about ps2 and ps1 games are u can do something with on dex but i haven';t heard what that is...do u happen to know or was that just someones typo in the other post...i'll find it and edit this post with that post if i can find it so u know what i'm talking about

SO what are the benefits other then out of region video and PS1/2 games? We can load anything CFW 3.55 users can and we can run legit disc up to FW 4.11 but did I read it is possible to install newer games as well?

Q: What if something better comes out? Am I stuck on DEX?
A: You're not stuck. Follow these instructions to go back to a normal retail PS3

Correction and this must be everyone know before they do it:

A: Yes you can downgrade with flasher and No if you modded your ps3 without a good hardware flash backup.

Hardware Flasher restore to CEX - If you have a flasher with good NAND/NOR flash backup when you were still in CEX and unmodded eEID

Full Software Conversion without a harware flasher - If you use a full software method, specially if you are going back to DEX - CEX. You will be getting a 100% brick for good. There a workaround on it but it's hell a lot of work to do it (not just a simple mm flash the cex method), specially restoring its capabilities like Blu-ray player and such.

edit!!
