How about an outline of the steps needed, inclusive of suggestions found to be helpful (or at least not cause any worsening of the problem), to help others install the firmware.

To get things started....


1. TURN OFF THE 990 AND THE COMPUTER
2. SWITCH THE USB TO SVC
3. CONNECT THE USB CABLE TO THE COMPUTER & 990
4. TURN ON THE 990
5. TURN ON THE COMPUTER
6. CLOSE ALL OPEN PROGRAMS ON THE COMPUTER

etc. etc.....

Maybe others can contribute to this outline of EXACT steps, in this simple "cookbook" form....
