PS3 How to DEX to CEX from E3 dump

@Alph4_XX
to get you out of brick on DEX, you should use 3.55 coreos with FSM patches and overwrite both ros regions and trvk on flasher dump. this even helped me on DEH

What do you mean with CoreOS with FSM patches? And for tvrk you mean the setting in ps3dumpchecker?

Another thing is that in norinspector by mysis it says that both region and target are DEX (bricked dump)

you have a lv1ldr brick...well, it has sounded first, you are aware of what you have to do and what you are doing. you can find links on devwiki for the downgrade patches which could be used with the dump-checker tools.

I am a DIY guy, so I cannot help you with these tools. on the other hand, it would be easier to let someone else patch your E3Flasher dump

- coreos is a binary blop of the individual bios files and trvk is a revoke patch -

I will send my NOR dump soon but if you can say me about that fsm patches i prefer that
 
see here:
https://www.psdevwiki.com/ps3/Downgrading_with_Hardware_flasher

for NOR
https://web.archive.org/web/20120512131150/http://ps3devwiki.com/files/flash/patches/NOR downgrade.rar

for NAND
https://web.archive.org/web/20120801235130/http://ps3devwiki.com/files/flash/patches/NAND downgrade/

you can either use those dump-checker tools, or apply them manually with hexeditor

after you have flashed back the patched dump, you have to use the official 3.55 DEX (v2) downgrade PUP

keep in mind, E3 dump needs to be byte-reversed and not plain text. so you have to 1st byte reverse the 'original' dump, apply patch and then byte reverse again patched dump, and only then you can flash it back to PS3. this is the manual way, dunno how those tools work, if they will automatically byte reverse and apply patch

Isn't an E3 flasher dump already byte-swapped?
 
@Alph4_XX
oh no, already too late, but please remove the public link. you should have pm'ed it to someone knowledgeable.

that is the main problem, E3 uses byte reversed data, but you cannot patch byte reversed, so you have to switch first, apply patch and then byte reverse again, to be able to flash with E3Flasher

Removed, i tried to patch with ps3dumpchecker the patch file you sent me but its "3.55 CEX Patched", it is going to work? And ps3dumpchecker does not give any errors applying patch in reversed dump, also rechecking it. Can i PM you my NOR dump? And what's that rvk file?

I did what you said to me with pyps3patcher:
Reswapped (Byteswapped: no), did the RVK+FSM 3.55 patch (patcher.py fsm command), reswapped (Byteswapped: yes)

it doesn't matter, cause lv1 is downgrade patched and DEX can run CEX kernel even without QA, but not vice versa
already have downloaded from the posted link, so I can patch it for you

basically, the patch consists of 2 binary files, which have to be applied on different hex offsets on the dump. a coreos binary file, which has to be applied on 2 different offsets, and a trvk binary file, which has to be applied on another different offset
