To downgrade your dash:
Get a hold of an EvoX gamesave exploit. Then, download Slayer's EvoX and extract the iso. Load up the gamesave exploit and FTP into your Xbox. Backup your C: partition to your PC and your eeprom/hdd information. Then, delete the C: partition on your Xbox and replace it with the one on Slayer's (System/All/C). Double check that ALL the files are there and that they are on root C: before resetting.

BTW, make sure you kernel is UNDER 5713 in order to downgrade...
Hi, I'm probably being dumb but how can I backup my eeprom/hdd information. Keeping in mind that I'm not using a modchip?
Thank you for the information! I found your posting in another post - very helpful.
ippo & thoalex: You can backup this information really easy when you load up the EvoX gamesave. Find the "Backup" option and click that. It will create a "backup" folder with the needed information wherever you ran EvoX from (In this case, the gamesave folder).
where are the game saves stored on the hdd?
