Make sure you've got nullbits Sync all set up before starting this process.
Press the reset button on the back of the keyboard with a pin.
Open the Windows Device Manager. When in update mode, the Ctrl and Alt appear as a COM device, i.e. COM1. Look under the "Ports (COM & LPT)" submenu. If you are unsure or have multiple COM devices in the list, you may need to unplug and retry step 2 in order to see which COM device disappears and reappears. Once you know the correct COM port, write it down.
C:\Program Files (x86)\Nullbits Sync\DropToolsand open
load.batwith your favorite text editor.
If you are updating the firmware on a Drop Ctrl keyboard, change the bin file to
massdrop_ctrl_default.bin. If you are updating an Alt keyboard, leave the bin file as is.
Edit the COM port to reflect match the COM port found in step 3.
Save the install script, close it, and double-click
load.batto run. Congratulations! Your keyboard should now be fully updated, and support the latest nullbits sync app. If you are having any issues, don't hesitate to contact us.
