Firmware Upgrade Issue My Book World NAS Edition 1 White Light

Device (WD My Book White Light 1TB WD10000H1NC-00) is working fine attached to iMac but remains stuck on version 01.01.08 with MioNet 4.3.1.13.

I’ve tried to upgrade firmware both auto & manual mode (using downloaded .img file) - the device appears to react to the request (white light flashes) but after a few moments it stops & remains fixed on version above.

Grateful for any/all advice.  Do I need to do a full reset to factory settings - with associated data loss issues? 

:smiley:

Update - I’ve managed to downgrade Mionet to 4.3.1.12 so something works but no change to ability to alter main firmware version.  

Hello,

Make sure you have followed the steps on the link bellow:

I have followed the manual instructions to the letter and the upgrade still fails (see other post) - PLEASE WD help me here - I need to get to latest firmware level to get Time Machine support (current version is only 1.01.18)
