Default Solution for the "KBD Boot Loader" on Windows 10

Hello to everyone,

Few days ago I faced a big problem with my Corsair Raptor K40. The LED were almost all shutdown, it wasn't recognized anymore by the software and the most annoying thing : the LED for CAPS LOCK, NUM LOCK... kept flashing.

I saw in my Control Panel that the Keyboard was now recognized by Windows as a "KBD Boot Loader". So I tried to search for a solution on the whole internet, but nobody seemed to have the solution. I got even more worried when I came across this post from Corsair : Windows 10 Compatibility
I also read somewhere what upgrading to Windows 10 would cause such problem but actually, I managed to make my Keyboard works again. So this solution is certainly mostly dedicated for people owning this Keyboard and having upgraded to Windows 10.

1. Download the last software and driver from the website of Corsair : Link
2. Install the software on your PC.
3. Now, go into your Control Panel
4. Go inside the section "View devices and printers". You should see your keyboard with the name "KBD Boot Loader"
5. Right-click on it and click on Properties
6. Inside the Properties, go in the Hardware section. You should see two device functions : HID Keyboard Device and USB Input Device.
7. Select the USB Input Device and click on "Properties".
8. Click on "Change Settings" and then go in the "Driver" Section. At this point, you should see this :


9. Here, you have to click on Update driver.
10. Click on "Browse my computer for driver software".
11. Click on "Let me pick from a list of device drivers on my computer"
12. Click on "Have Disk" and then click on "Browse" for the next window.
13. Here, you have to find a special file inside the software you installed. This is the path I have : C:\Program Files (x86)\Corsair\K40 firmware update\Driver\X64
(If you have a 32bits version of Windows, select the X86 folder instead)
You'll have to select the file "CORK40.inf"



14. Press "OK" to validate the installation. Now back in the Hardware properties of the device, the "USB Input Device" should have turned into "Corsair K40 Gaming Keyboard".

15. Now select the HID Keyboard Device and click on "Properties".
16. Click on "Change settings".
17. Go in the Driver section and click on "Uninstall". Validate every message of Windows coming for this uninstallation
18. Now, in the Hardware section there should be only the "Corsair K40 Gaming Keyboard" remaining even if your keyboard will still shows as "KBD Boot Loader". Don't worry we're almost done !
19. Install the "K40FwUpdate" file. Once it's done, the updater should show up.
20. Launch the update action on your keyboard (which should be recognized now) and wait for it to install his files.
21. You're done ! Your keyboard should (magically) lights up again !

I don't know if it could work on other keyboards from the K series, but I hope it'll help people :).

It looks similar for the legacy K and M series peripherals guide here;

Either way, glad to hear the keyboard is working fine and that the flashing indicator lights probably indicates the keyboard is in bootloader mode.

Indeed. Actually I tried to use this method but it didn't worked, I had to tweak it a bit so it could work.

The firmware updater should be in the archive with the software as well.

Most likely its because you flash a firmware for the K40 instead of the K30.

You will need to contact customer service and see if they can provide you with an firmware updater or to RMA the keyboard to replace it.

You should find the file inside of the ZIP you downloaded in step 1.

Does anybody know by any chance if there is such a firmware update for K30? I have a K30, I have this same problem, but I haven't had any luck finding a firmware update for this keyboard :/
