Mittns Posted September 7 Report Share Posted September 7 After I got a bit annoyed that some saved games no longer work because of the HDD key (XsavSig doesn't work either), I got the eeprom out of my old xbox and created a small program using Arduino to read the eeprom data. Â Â Â The HDD key is encrypted with the RC4 algorithm. I assume that you have to decrypt it first in order to be able to use it in config magic? As far as I know, the RC4 key is stored somewhere else in the Xbox, does anyone know where? Is the key unique for every xbox? Quote Link to comment Share on other sites More sharing options...
dtomcat Posted September 7 Report Share Posted September 7 Just store the entire eeprom as a whole to eeprom.bin and use something like liveinfo to get the fully decrypted eeprom. Â 1 1 Quote Link to comment Share on other sites More sharing options...

Â Great, this seems to work! Copied the data from arduino and converted it to a bin file. Â I mean, i hope that the decryption is correct because theres only xbox version 1.0, 1.1 and 1.6 in the list, my backup is from an 1.4.

dtomcat Posted September 7 Report Share Posted September 7 I believe 1.1 is 1.1-1.4 1 Quote Link to comment Share on other sites More sharing options...
