I have been trying for two weeks now to get my homemade XDK to work. I orginally copied the Complex(4627) XDK files onto my xbox and flashed my chip with the complex debug bios(4627). The Xbox booted into error 21. I then proceeded to take everything off the hardrive (Except save files) and try again. Error 21 was produced once more. I then installed PBL 1.3 and of course used the Complex Bios BFM. This attempt also gave me error 21. When I load Xshell.xbe manually using an Xecutor2 Bios(4981) it takes me into the Xbox Dash.
I have seen error 21 occur when the files of the dash are not all there, but I have installed the files correctly.
