How to Fix Nollie Stuck in Bootloader (Unbrick Guide)

Sometimes third-party RGB software may send incorrect or malformed USB HID packets, or an interrupted firmware update may fail midway. When this happens, your Nollie controller can become “soft bricked” — trapped inside its onboard microcontroller bootloader instead of booting into its normal lighting runtime.

In this state, the controller may appear unresponsive, fail to display any RGB lighting, or fail to be recognized by SignalRGB or OpenRGB.

Fortunately, you do not need to open up your controller or use hardware programmers. You can easily rescue and exit the bootloader over standard USB using HIDQuickWrite.

Download the Required Tools

We highly recommend HIDQuickWrite, a lightweight open-source HID utility developed by our community member Morg:

Platform	Download Link	Notes
Windows (x64)	Download Windows 64-bit	Ready-to-run .exe
Linux (x64)	Download Linux 64 AppImage	Portable executable AppImage
Source Code	GitLab Repository	Source code & docs by Morg
HIDAPI Releases	libusb/hidapi Releases	If it prompts missing HidApi.dll

Extract the downloaded archive (if compressed) to an easily accessible folder such as your Desktop or Downloads folder.

Close All Background RGB Software

Before opening HIDQuickWrite, make sure to fully close any running RGB software:

• SignalRGB (Right-click system tray icon -> Quit SignalRGB)
• OpenRGB
• Nexus
• Skydimo
• Any other motherboard or peripheral lighting software

If another application has an open handle to the Nollie controller, HIDQuickWrite will not be able to claim the USB interface to send recovery packets.

Run HIDQuickWrite and Send the Exit Command

Follow these step-by-step instructions to kick the controller out of the bootloader:

1. Launch HIDQuickWrite (HIDQuickWrite.exe on Windows or the AppImage on Linux).
2. Select your device: Click the top dropdown menu and select your Nollie controller.
   • Example: [16D5:4716 U=0001 P=0xFF00 I=0] nollie.cn - Nollie 16CH RGB (or your specific Nollie 8 / 16 / 32 / 2W / 1 model).
   • Tip: If you don’t see your device listed, click the blue Refresh icon on the right.
3. Select hid_write: In the second dropdown (under the device selection), choose hid_write.
4. Enter the exit command: In the text box on the right, type:

   00 83

5. Keep default options:
   • Leave Pad with 1 zero unchecked.
   • Leave Sleep interval (ms) set to 0.
6. Confirm safety: Check the box for “I know what I’m doing” in the lower left corner.
7. Click Send: Click the large Send button at the bottom.

Verification

As soon as you click Send:

1. The bootloader will acknowledge the 00 83 command and immediately jump to the controller’s main application firmware.
2. Windows will briefly chime or re-enumerate the USB device.
3. Your default lighting effect will immediately resume on your fans and LED strips!

You can now relaunch SignalRGB, OpenRGB, Skydimo or Nexus. If the issue occurred during a failed firmware update, you can now safely re-flash the firmware via NollieRGB.
