Hello, i installed razer firmware update for my Razer Viper 8000hz and now, when i use higher dpi as 8000-20000 my mouse cursor shakes,twitches,jumps,erratic movement uncontrollably, i updated the firmware to

v1.02.00_r1, and it has totally ruined my experience in gaming, because i play with highest dpi all the time and now i cannot and i need to to back to v1.01.00_r1, but i cannot find that firmware, can anyone please help me, i have done every other fix and still the same.



Thank you
