Hi everyone,

I have a Razer Basilisk Ultimate wireless mouse, and after running the official firmware update using the updater tool, my mouse not detect. after click on left right and scroll botton enters bootloader mode and update but after update i hear the unplug sound and app says connect mouse with cable. The device version field in the updater remains blank during the update process.

Details:

• The mouse works neither wirelessly nor wired after the update.

• The red LED under the mouse is solidly on.

• I've tested the mouse on multiple computers and with different cables; the issue persists.

• Windows is fully updated, and drivers have been reinstalled.

• When connected, the mouse is not detected in Device Manager or anywhere else.

• The updater tool shows the mouse in bootloader mode but cannot complete a successful update.

I’ve tried:

• Using the official updater tool multiple times.

• Entering bootloader mode manually with button combinations.

• Disconnecting and reinstalling drivers.

• Using both wired and wireless modes.

No luck so far. Has anyone faced a similar issue or found a solution to recover the mouse?

Thanks in advance for any advice!
