it said "error: unknown command" because it dosn't have /C and /Q. So i go with AFUWIN R0270Y0.ROM /P /B /N /E /K /REBOOT and i got same message i had before
Same error message. I tried on DOS mode with AFUDOS R0270Y0.ROM /P /N /E and i got "error: this is write protected flash part"
You need to Boot to DOS and use AFUDOS from a USB Drive/Floppy or CD. You can't Run AFUDOS from within Windows.
