I have a Tartarus v2 (RZ07-0227) that ive used for the last few years, hadnt had any issue with it at all. I saw on the synapse that 3 was being retired for 4 and i bit the bullet. fully uninstalled 3 downloaded and installed 4, plugged it in and it lights up fine so i didnt play anything right away so i just thought all was normal. finally went to played something later that night and only buttons 17-20, the scroll wheel and the dpad work. synapse doesnt recognize any of the buttons or even the profile change button. i uninstalled 4 and reinstalled 3, tried on my laptop and rog ally. nothing has fixed the issue. what can i do?

Same Issue.. if anyone know how to fix this.. all my keys are not working only the joystick, and 20

 

    I KNOW HOW TO FIX IT I JUST FIXED MINE

    all you have to do it DISCONNECT the TARTARUS FROM USB and go into razer synapse and on SYNAPSE page go to DEVICES AND MODULES and find the Tartarus device and go to the right and click REMOVE. it will delete the device and when you plug back the Tartarus it will redownload the files and BOOM it started working for me like it use to. My theory is that when Synapse updated it copied over the user profiles and duplicated them resulting in an error on which profile to use so it just defaults to its factory button layout. hope this helps

        My issue is that it doesnt show my tartarus on the razer app at all to remove it anymore. 

        I have gone back and forth with it where they insisted on first that it was physical damage this or that I need to uninstall the driver or the software or try a different port (All of which I did) But admitting that the only problem was that THEIR software update is what caused this issue is NOT something they would entertain or admit. There is nothing wrong with my device or the system level drivers for it. AS PROOF for simple key swap assignments  which of course sends Synaptic into a tizzy can be done (isolated to a specific device) WITH FREE SOFTWARE KeyTik (Clunky interface but once set up functions) As for Macros the reWASD software (I tested it on the 7 day free trial) has a smooth interface AND runs macros. With BOTH of these software my device functions perfectly, no lag no issues. So yes my device is not the problem, the software is. Please fix your software Razer. I hope this helps someone.
