Firmware Upgrade to a Sony HAP-Z1ES with a very old software version

The HAP-Z1ES software version on the machine now is 0015261R .  The current firmware upgrade (version 18120R) provides improvements over version 18033R so I am not sure how many prior firware upgrades there have been.  

 

What is the best practice to bring this machine to a current software version?  Do I just install 18120R or would it be adviseable to progressively upgrade the machine through prior upgrades....assuming I can even find a link to these prior upgrades?

Hi Mac5u,

 

Welcome to the SONY Community!

 

In relation to your concern about the firmware upgrade, since your unit doesn't have the current version installed as of the moment it is advisable to upgrade the software to version 18120R already instead of progressively upgrade. Also, the links for older versions are not available. 

 

You can follow the steps from this link whenever your ready upgrading the software of your device.
