bobby0787 0 Posted October 14, 2019 I'm trying to update the firmware of my H500M because MasterPlus+ notify me the version 001 is available and I've the v 000. When I start the update process, compare a window that say me to unplug all the cables from the case (usb, Sata, mobo, etc) the to plus the usb. After that it's unable to start the update. I've tried to update the firmware from the CM website, but same problem? I know the some other guys had this problem? Does anybody know how to solve it? Thanks a lot Quote Share this post Link to post Share on other sites
Brendan 0 Posted October 30, 2019 Hey Bobby, I had the same issue at first when i got my case, and I was afraid about screwing it up because of reviews on youtube from reviewers who accidentally fried the controller. I've found that some of the coolermaster instructions are pretty cryptic. While I don't remember exactly what I did I encourage you to try it with only the ub plugged into the controller, because I remember thinking that the instructions sucked once I figured it out.
