WD 3TB My Book Live Problems

Well I finally received my replacement Hard drive. I took a chance and purchased a factory refurbished 4TB Red Pro because to be honest I wasn’t positive that the problem was the HDD.


I used this guide [ [GUIDE] Debrick MyBookLive v2.0 ] a special thanks to “nfodiz” for taking the time to put it together.
Unfortunately I encountered an error " 31103 - Upgrade download failure. Please try your upgrade again."
Has anyone encountered and solved the error.
I just need to be sure that the firmware / image i used wasn’t tainted, giving someone access to my cloud and by extension the rest of my network.
