A mod chip is a piece of hardware that has to be integrated into the console's circuit board in such a way that it can bypass the built-in security features - I don't think that can be done in a none-tech-invasive way. As far as I know, you cannot 'jailbreak' an Xbox 360 with software alone.
Please note that installing a mod chip voids your warranty and in itself is illegal in US (the DMCA makes it illegal to circumvent copy protection, regardless of the legality of the reason for your circumvention) and most other territories. You also risk 'bricking' your console with future firmware upgrades (that ship with newer games). Finally, many publishers employ additional security measures that prevent copied disks from working - there is no guarantee that you can even play your backups (most publishers do provide replacement disks at no or marginal cost, if your original copy is damaged). |
