I am dropping this here because I see a lot of people wanting to play retail game disc on there XDK's. This is not for RGH or JTAG it's for true DEVKITS... Guys this is totally safe to use and will allow you to do a lot of things retails can do. One being it will allow you to play retail disc without any modifications to the games. YOU MUST BE ON THE RECOVERY FOR 17489 IN ORDER TO USE THIS SHADOWBOOT!!! instructions Place the filesystems , devkit folders and the shadowboot rom on the root of your hdd and reboot. Shadowboot and files https://www.mediafire.com/file/krta15lydy5jrpo/XDK_Shadowboot_17526.rar/file LINK TO : XDKRecoveryXenon21256.18 https://mega.nz/#!xfIwhCqR!6LiffjYbt_ht5doFePl8KiDaMklemJTjycP6zffFOnw XNA Stealth Server files to get online "free service" https://www.mediafire.com/file/igx51r16qdiscag/Xna_Stealth_online_file_pack.rar/file THERE IS NO SUPPORT FOR RGLOADER NANDS WITH THIS STEALTH SERVICE To Answer a few questions that's been asked : XDK with this Shadowboot and files can do all that a Retail/RGH can. You still need a stealth service to get online. and its Xbox Live just like a retail with retail accounts. I have added a link to my free stealth server for XDK and RGH's, but KV life is not good it's a few days at the most. I would need some help from peeps around here to make better KV life happen. If you decide to use the stealth server all I ask is Once you are connected that you use the feature from the Xbox blades to change your Username to your Assembler Screenname from here thanks!
