[HELP] DEX to CEX.. Urgent, please

[viperturbo]

Hello.

I've a 60GB nand PS3, converted to DEX.
The problem is, i've losted my original nand flash, and before you all asking if i can recover it, etc.. the answer is no.
I've read some topics with some people saying it is possible to convert back do CEX without original nand file, that it is possible to dump DEX nand and convert it to a CEX nand.
I've already read some tutorials, including about c2d.exe v2, but i don't know how to use.. I open it, but after a few seconds closes automaticly. How do i use it? I can't find any tutorial about it, if i need extra software, or how to name the files.
In the read me file there's no info on how to use it.

Is it possible i can send some one my DEX nand and eid0 key file, and sending me back the correct file to use on multiman so i can restore back to cex? I want to convert back because, i want to install 4.25, since now i have a job, and i can buy more games and play online with friends.

Can some one please help me, or tell me what i can do step by step, and how to use?

I would be apreciated.

Thanks.

Just do it the same way you went to dex.

Make ur dump in dex using multiman edit it back to cex then reinstall it just make sure you have a way to go to.service mode just incase

How do i use c2d.exe v2 to change region ID?
Can you please explain me? Cause i have the files, but no guide on how to use c2d.exe

You have to rename the files I can't remember the names bit once you rename them it will work use the windows GUI version it shows you what to rename them

Dont think cex2dex.exe will work as it only has option for CEX to DEX not DEX to CEX.

What it does is change the eid_root_key buy i think a few hex values to make it read as DEX console then patches the CEX
So if you put a dex dump in there it will change overwrite this with the same thing or give errors.

The GUI works I believe as i used to make a cex flash I haven't tested it though just made cex bin

I have the GUI version, is it ACTUALLY a cex.bin or is it just named that?

I just renamed it to that after from dump.bin I (think) it does do it as if the dump is dex it will change to cex their like a few versions about I think it was in the read me if I read it wrong i don't knw as like I said not tried it yet I might have even just used the cmd line version its been ages can't remember since I made it

In the "readme" file it says this:

"Usage: c2d.exe eid_key_file.bin in_flash.bin out_flash.bin [target_id]"

I know that using this c2d.exe v2 it works for changing a dex to cex, but i have never tryed it yet.
There are a lot of people who have used this, and have positive feedback.

My doubt this moment is: I've changed the files to names "eid_key_file.bin", "in_flash.bin" and "out_flash.bin".. But where do i put [TARGET ID]?? a txt file? Or something else?

I dont think you "make" a target id file so to say, just type in the number in command prompt that corresponds to what you want, like 82 is dex, 85 Europe etc

EDIT: i think the first target ID you manually type in like for you would be 82 (for dex) then say you want retail Europe, so in the next target ID you type 85
or
You use c2d.exe eid_root_key.bin flashDEX.bin flashCEX.bin 85 (for europe)
assuming eid_root_key already provides input target id (or dex flash input does)

Usage:

c2d - Changes REGION/TARGET_ID in PS3 NOR flash
Usage: c2d.exe eid_key_file.bin in_flash.bin out_flash.bin [target_id][target_id]: 82..8C
82 (DEX) (default)
83 (JAPAN)
84 (USA/CANADA)
85 (EUROPE)
86 (KOREA)
87 (UK)
88 (MEXICO)
89 (AUSTRALIA)
8A (SE ASIA)
8B (TAIWAN)
8C (RUS/ASIA)

It only mentions NOR, however I think you can use NAND and just change any instance of NOR to NAND
