My little experience with CEX to DEX conversion I just converted my console without formating my hard drive, I used an old cfw "CFW355-OTHEROS++.PUP" instead of "OTHEROS-22GB.PUP" then I dumped the nor flash with memdump_0.01-FINAL, and to be sure I made another dump in petitboot following @kneeandarrow tutorial. I took the two files and compared them in HxD and they were identical. then I followed @GraVoX959 0 tutorial on getting "dump_eid0.bin" after that I converted the NOR file to dex.bin using "CEX2DEX" and "C2D" compared the output file in HxD (both identical) Then I flashed the new dex.bin in petitboot following @kneeandarrow steps. (BTW reading and flashing nor in multiman 04.04.03 didn't work for me, MMos don't ask the third question. maybe I used an old update ). now I'm on 4.11 dex thanks again to @kneeandarrow and @GraVoX959 0 and andbey0nd and Gunner54 P.S. Don't mind my English.
