Report Poseidon Z RGB firmware at 0 in Mechanical Posted November 25, 2015 I did a lot of reinstalls and reboots while working on it, it was really annoying. The issue I had was that it would say it completed the update, but it was apparently not really updated. On the other PC I had not installed any Thermaltake keyboards, probably no special keyboard drivers/installers were ever installed on it. I installed just the 0>30 updater first, and it worked. Then I did the other one. There are several possibilities... Windows drivers are complicated, and prone to issues due to the constant OS updates, interference from other settings and drivers, variations in USB controllers and hardware... It could be that the installer is unable to update a file that exists already, which is why I did the 30 update before installiing 36. I read a lot of things which made no obvious difference.... 1) Disconnect the keyboard. 2) Uninstall all the thermaltake stuff 3) Reboot 4) Install 30 drivers 5) Connect keyboard ( use a USB port you have not used before) Try yet another computer. Try going to a restore point in windows. Make sure all Windows updates are on automatic and updated. If you have having any other issues with the PC, could be related... Check the event logs, application and system. Use the FN-ESC reset. I did all these things because they work sometimes when installing hardware. But when I connected it to the other PC, it worked first try. Also, I did the 30 then the 36 and it worked, but it may have worked on that other PC if I had gone right to the 36 fw. I can't say what exactly resolved my issue, there's multiple variables.... And my issue was a little different. Be sure to contact Thermaltake support, too, they may have more info.
