i also messed up my xbox. i soft modded it. and had it working for a while untill i put a bunch of snes and nes roms on it. now whenever i turn it on i get error 21 and it says it requires service. i can still boot up games. but i cannot get to the dash board. does anyone know what to do?
Error Code 21 - anywhere - This error says that the machine was booted to display a error, basically someone told the machine to reboot (or launch a xbe) with this flag, and the error code just means its been rebooted by the flag I WOULD REFORMAT THE DRIVE
