NEC ND-3550A Flashing Error

I am trying to upgrade an NEC ND-3550A firmware’s version from 1.05 to 1.G6. Yet when I run NEC’s updater all I get is Flashing Error. Any thoughts on this :confused:

Wrong firmware, wrong update.

Search for binflash.

I saw binflash out there, but if I use it what would you suggest that I upgrade my firmware to? Also, why can I not get it to take the 1.G6 version?

I would use 1.07 or 1.07bt.

I used the 1.07 and it works great.
