Hello,

Ok, I have had a premodded Executer 2.2 Pro for about a week. It took me a little while to realize that you can't actually do anything with the Cromwell BIOS. So, I located X2/4977-02 (I think that is the right BIOS number), read a few tutorials, converted my 256kb BIOS to 1MB using X2BM, placed some dummy files on a CD-R and ISO'ed the thing. I double-checked to make sure that the XBox could read my CD-R. Then, I tried to Reflash to the new 4977 BIOs. Everything seemed to proceed normally. It located my 1MB BIOS file, flashed it, and turned the XBox off just as I had expected.

When I tried rebooting the XBOX in modchip mode, I get a standard X-Box splash/intro screen, and then to my great horror, I was greeted with a black screen with green lettering that stated "Oops, something is wrong" and listed "error code 21" in the upper left hand corner. Error Code 21 is listed as unspecified. The X-Box now just flashes from red to green and will not boot. If I disable the modchip, the X-Box still boots perfectly. Did I somehow fry the modchip? What can I do to recover from this?

Please excuse all the newbie questions! I am not all that familiar with XBox modding as of yet!

Thanks

What does it say when booting? Does it say executer 2 or MS when you enable the chip ? If it

If it says executer 2 you can now play backups of your games. Just insert your game and turn your console on. Because you have a Executer 2.2 pro you can also flash your bios with the LTP connector on the back of your Xbox. (there are also tutorials available)

The next step is to install a dashboard such as Evolution X (Evox). You can find a lot of tutorials on how to fix this.

Error code 21 means:

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

And also try to search the forum for answers to your questions.

Hope this helps you.

OK, the screen that comes up on my "new" bios looks exactly like the standard MS intro screen. It does not say XEcuter 2 anywhere. Also, a backup that I tested does not work. Does that mean I probably downloaded a bogus bios file?

I am going to try and reflash to Cromwell, which I know works, with the LPT method and then locating a version of X2 or Evox that I know is legitamate. Hopefully, I'll have a little luck!
