since Duke is away, i better do this on my own.


is this correct way of copying ME region using the HxD Editor app?

1. ) Open original ROM file
2. ) search for KRID, put my cursor just after all the FFF's end. so beginning of 20 20
3. ) Menu bar > Click "Edit" and click "Select Block"
4. ) in the length field type: 17D000
5. ) in the Menu bar > click "Copy
6. ) Open New rom File that you downloaded from google
7. ) Search KRID, put my cursor just after all the FFF's end. so beginning of 20 20
8. ) Menu bar > Click "Edit" and click "Select Block"
9. ) in the length field type: 17D000
10. ) in the Menu bar > click "Paste write"
11. ) Save

ok, i took it apart and reassemble again, then did a PRAM reset. it seems to did the job and no more auto turn on.

i then run ASD, no error found.

so its a success?
