I messed up. Was fiddling around with configmagic trying to lock the HDD on my chipped Xbox 1.6 so I can transfer and use the HDD on my softmodded Xbox. I followed this guide here: https://www.biline.ca/xbox_uxe_hd2.htm
I was able to update the EEPROM as stated and locked the HDD so it can be used on the softmodded Xbox. That worked fine. But now my chipped Xbox turns on but no picture or video whatsoever. I don't know what to do next...
