– Never interrupt an upload in progress. You can “brick” and damage the CPU. Always wait for the upload to finish.

– Always ground yourself before opening the amp (by pinching the vinyl ground pin, for example). Failure to do so can damage the fragile electronics.

You will need:

– The Billie Update program and firmware: download here
– A Windows PC (or Mac in Bootcamp mode)
– A USB to micro-USB cable (example)
– A Philips screwdriver (cross-shaped head -for older Billie models)
– A padded work surface (a piece of foam or a pillow will do).

NOTE | make sure the volume knob has clearance to turn during the update process.

1. With the Billie amp UNPLUGGED, remove the tubes and flip it over on its back making sure the volume knob has clearance to turn.

2. Unscrew the 4 screws holding the cover. Remove the cover by pushing it to one side and lifting the other.

NOTE | the amp will reset several times. The volume knob needs to be able to rotate freely. Optionally, you can pull off the volume knob.

3. With the front of the amp facing you, locate the jumpers near the volume knob and switch them over to the 2 leftmost pins, labeled USB RX & MCU TX and USB TX & MCU RX.

Windows may present a warning window, click on “Run Anyway”. If this is the first time you use the Billie Updater, install the Windows driver found in the DRIVER folder (CH34x_Install_Windows_v3_4.exe). A restart is recommended.

8. Run the Billie Update program: If all is good and ready, the second button should say ‘Billie Detected’. You are now ready to update. Click the “Start Update” button and wait for update to complete. If the status bar says “update error”, try again quitting and relaunching app and pressing the update button once more.
