Below are the verification checksums, as follows:

  • 4.31 CEX patched update4 PUP: a1781d38dc5f3d54830615ed6b6c3870
  • 4.30 DEX patched PUP: f59a4247449be038fea354f3462c3af6

Finally, from Cyberskunk: First, nice job Miralatijera. Second, It is true 4.30 REX has been ready for a few weeks now and it does use a patched 430 lv1ldr instead of the 421 lv1ldr that does not have the check. I read a single sentence on ps3 dev wiki that stated there was a check in lv1ldr with no other details about it.. so i had a look.. found it.. patched it.. Job done. So guess i would have to give credit to the person that shared that snippet of info to work from.. Thanks

thats not true how do you think rogeros firmwares are working.you can go from cfw 4.30 v2.03 to 2.05 that's a 4.30 over an 4.30 and from rebug 4.21 to rogeros 4.30 thats a 4.21 to 4.30 cfw...

I'm sure it's something simple, but no idea what.

Maybe you have the 4.21ita and sproof to 4.31, so you have to install 3.55 ofw dex first than 4.30CFW!

Any clues?

after installed 'this dex cfw', can it turn back to 'dex cfw 355' with 'dex cfw 355 downgrade' ?

That's deeply sad. Not for me but those who are still on OFw 4.30

you can link this to download the patcher: xdelta.org the current package includes the patch for 4.31 cex, it may be confusing

Command line: xdelta3.exe -d -s "PS3UPDAT_4.30_DEX.PUP" "dex430cfw.xdelta" "output_file"

The right md5 hash after you apply the patch is: f59a4247449be038fea354f3462c3af6

Mega link is for download the tool, what we need for patching the OFW "DeltaPatcher.exe" and the download is = dex430cfw.xdelta

This topic seemed very interesting. It had my hopes up for installing it on OFW 4.31, but it turns out you can't yet still nice work though.
