Cex to Dex Flash Patcher Released

by ps3iso on July 12, 2012

andbey0nd has released an easy CEX to DEX conversion tool. This tool currently only works with the 16mb NOR.

To quote:

 works for 16MB flash dumps (NOR) only

 also if for some reason a WRONG EID key is provided - the program will abort and will not generate invalid DEX flash.. so no chance for bricking

 if an output DEX flash file is created - it means that it is valid

Readme:

c2d.exe (win32 app)
===================

Requires:

* OpenSSL 1.0.1 installed in c:openssl or d:openssl (http://slproweb.com/download/Win32OpenS … 1_0_1c.exe)

* CEX (NOR) flash dump
* Extract c2d.rar in a local folder (c:c2d or d:c2d)

Usage:
