Applies to Models: all WRN series recorders as of 01/01/2021

Summary:

Due to the nature of the WRN series recorder being a computer running Linux, you are required to update the operating system from time to time. This article details steps to accomplish this update; if Hanwha Techwin America releases any updates for this model recorder, they will be through an ISO that has the drivers and updates contained within that ISO; this would necessitate a re-image of the Linux OS on this recorder. These instructions will walk you through that process.

Warning: You will need a blank 8GB or larger USB drive to perform this process.  
If you use a smaller drive, the process will fail with an error.
This process will reformat your USB drive and erase all the data stored on it.
We recommend using a brand new thumb drive for this process.
If a new USB drive is unavailable, copy off all data from the drive
before performing the steps below.

Step By Step Guide:

1. Hook up a Keyboard and Mouse to the WRN

NOTE: The initial stages of re-imaging require a physical keyboard,
No on-screen keyboards are available in the re-image process

2. Back up your Wave configuration if possible

NOTE: Even though you might be locked out of the WRN in some cases
if you can log into Wave from a workstation, you can backup the 
License keys and the Wave database
