I am aware that you can update an xbox 1.6 eeprom with configmagic. My question is how does it work? I always thought that the xbox 1.6 eeprom was unchangable due to it not having a tsop, making it essentially frozen in time.
A few years ago, I wanted to change my xbox 1.6b hard disc key (which is stored in the eeprom), to match the one in my 1.6. So that all my saves from the 1.6 would work with the 1.6b (some saves are signed by the hard disc key). So I took my xbox's to a modder, he did all the work, cloned the hard drives, copied the keys etc. Both xbox's now had identical hard drives, and hdd keys, and most importantly, all the saves worked. Now both xbox's 1.6 and 1.6b and are unmodded (as far as I know), so how did he achieve this if the eeproms are supposed to be unchangeable? Configmagic from what I have read, can do it, but if the eeprom is supposed to be unchangeable, then how does it work? Is there a softmod or something on the hard drive that has a separete eeprom that overrides the main one?
This has always baffled me, I must admit I do not know very much about modding and I may have my facts wrong. I am also unable to contact this modder to ask him what he did, I just told him what I wanted and he did it. I do remember him saying something about an algorithm he used, but thats about it. I guess I should have inquired more at the time.
