Fernand wroteIf I mod it can I install some custom firmware with additional options like let's say a custom ROM for an android phone?
Do I need to add an internal HDD in order to save games onto it?
Can I download ISOs from XXXXXXXX and play them without buying games from a shop?
Thanks a lot for your help
Be careful, no piracy allowed.
1. Yes you must add a HDD to save games on it.
2. As long as you have the appropriate burner for them then yes (these days burning a 360 game isn't as easy as it was some 3 years ago) - save your time and just buy them
You cannot flash your own software to an xbox .. you can glitch it or jtag it to run unsigned code but that needs some hardware peripherals and some soldering skills.
@vegetaleb - you must clear your NAND or something along those lines to de-flag an xbox; not sure of the exact logistics but it exits / it's possible
