860C Display Bootloader for Firmware Programming

To get started, you will need a Bootloader Box to connect your 860C Display to your Computer

PROGRAMMING OR ATTEMPTING TO PROGRAM YOUR OWN DISPLAY/MOTOR WITH OSF OR ANY FIRMWARE FILE IN GENERAL DOES VOID YOUR WARRANTY AND SHOULD BE DONE AT YOUR OWN RISK!

850C Displays are no longer recommended as changes in hardware often cause failure of OSF loading and 'brick' the display.

Note: You will also need a TSDZ2 Motor Contoller Firmware Programming Cable to program your Motor Controller with a matching OSF Version. This is a separate installation/updating process detailed in our article: 'TSDZ2 Motor Controller Firmware Programming'. The display AND motor controller must both be programmed independently to successfully run Open Source Firmware.

Step 1 - Download 'APT Burn Tools' 860c Display Bootloader Firmware Update Software, and the Most Recent Version of the 860C Display Open Source Firmware for TSDZ2.

Step 1a - Download APT Burn Tools (APT's 860C Display Bootloader Firmware Update Software) - The file is a direct executable - no installation process - it is good to go.

Step 1b - Download 860C Display Open Source Firmware for TSDZ2 - Version 20.1C.3 (which pairs with Motor Version 20.1C.3)

NOTE: 850C Display are NOT recommended as changes in hardware often cause failure of OSF loading and 'brick' the display.

Step 2 - Connect the 860C Display to Bootloader Box to Computer

Step 2 - Just plug it all in - any order is fine. Both lights should be lit on the bootloader. Leave the display OFF for this process, but make sure the remote / button panel is plugged in.

Step 2 - Connect 850C to Bootloader Box to Computer

Step 3 - Identify the COM/Port and Download Driver if Needed

Step 3a - Open the device/hardware manager and note the Port / COM# your bootloader box is connected to.

Step 3b - Download the driver (if needed) here: Silicon Labs CP210X Drivers (for APT's 860C Bootloader)

Note: If you choose to make your own bootloader box (with either USB to UART cable and a wire from your battery, or another USB step up driver) then you may need to note the device name and manually search for a driver.

Step 3 - Identify COM/Port and Download Driver if Needed

Step 4 - Open APT Burn Tools, Configure, and Update your 860C Display Firmware

Step 4a - Open the Apt Burn Tools Software which was Downloaded in Step 1.

Step 4b - Select the COM# of your Bootloader Box which was Determined in Step 3.

Step 4c - Press the 'Open Port' button.

Step 4d - Select the Firmware File which was Downloaded in Step 1.

Step 4e - Press the 'Update Firmware button

Step 4f - On your 860C Display remote / button panel - short press the power button, and wait until the status bar reaches 100% before unplugging.

You will see the % Bar start to rise, and once it gets to 100% and you see that the update was successfully completed in the log, you can immediately unplug your 860C display - no need to press any buttons on the software, exit out first, or anything like that - you are good to go!

While the display is plugged into the bootloader box which is plugged into the computer - you may want to briefly turn on the display to verify that the update took.

Step 4 - Open APT Burn Tools, Configure, and Update your 850C Display's Firmware
