Razer Basilisk Ultimate not working using the dongle

Hello,

I'm reaching out because I'm having a problem with my Razer Basilisk Ultimate.

My mouse no longer works with the wireless dongle. Here’s what I’ve tried:
 

  • Pairing with the software: RazerMousePairingUtility_v1.00.02_r1 → pairing always fails.
  • Updating the mouse firmware using: BasiliskUltimate_00880086_FirmwareUpdater_v1.08.00_r1 → the process stops at 40% and restarts repeatedly.
  • Using the dongle firmware tool: RazerUSBHyperspeedDongleUtility_v1.00.11_r1 → also unsuccessful.

My dongle shows up as RC30-031701 / PID_0088.


Thanks in advance !
