How to extract binary file

Eijamaria

Hi, my product NBG6604 seems to be an end-of-life product so the new firmware is a zip file. So how can I extract the existing binary file? And what does it mean that I possibly have to reconfigure? How can it be done?

Hello @Eijamaria

Welcome to the forum.

You are correct that the NBG6604 is End of Service from Zyxel.

There is a ZIP file of the last firmware available at https://www.zyxel.com/uk/en-gb/support/download?model=nbg6604

I think that it is ZIPed using a Lempel-Ziv-Welch or Lempel-Ziv-Markov compression method that a program such as 7-ZIP (see https://www.7-zip.org/ ) can uncompress and leave you with a .bin file.

The user guide https://download.zyxel.com/NBG6604/user_guide/NBG6604_v1_ed3.pdf explains how to do firmware upgrade once you have the .bin file.

I hope that this is helpful.

Kind regards,

Tony
