(adsbygoogle = window.adsbygoogle || []).push({}); okay i downgraded to 3.55 to retrieve the eid_root_key

then i went to CFW 4.21 rebug and flash NOR/NAND (i have NAND) then went to my computer and renamed the NAND file to flashCEX.bin and eid_root_key.bin

then i went to the command prompt and typed this c2d.exe eid_root_key.bin flashCEX.bin flashDEX.bin 82

when i press enter this is what i get "wrong format of EID file: 16777216 bytes (16MB) expected, but 251396096 found"

so why is it doing this
