22:28:16| Hold 'C' button on phone and connect phone NOW.
22:28:16| You have 30 seconds...
22:28:16|
22:28:46| Error: Cannot open phone communication port
22:28:48| Disconnected... Unplug the phone

thanks. im at this bit:

Step 2.
Select the firmwares (make sure you extract them first) by clicking the "..." buttons or simply dragging the file from the explorer to the box (don't get mixed up with FS and MAIN).
Click "Flash" and wait (this takes a while, 6-7 minutes is normal).

what files do i have to get?

NVM . got it thanks alot dude ur a star
