Hello. I want to update the factory firmware on my TSDZ8 to the latest one. Where can I get the latest firmware?

I also have a B02NU display. Is it possible to update the factory firmware on the TSDZ8 with this display?

I’m using the Facebook firmware (not the Open Source). It’s loaded straight to the motor via the speed sensor connector, not using the display.

Is this the newest firmware? Or the old one?


Google's neural network says the release date for this firmware is August 2024.

Not sure. Mine came with the version where level 1&2 are useless. That’s fixed and the max power went up.

Has anyone in the tsdz8 community on Facebook posted the latest factory firmware for the tsdz8?


I currently have exactly this firmware, where levels 1 and 2 are useless. It's noticeable.
 
I found a J-Link and TSDZ8 Wiki from Ali Express, it shows the pin-out information and has an instructional write up in English.

Also, in order to avoid damage to the controller, it is extremely important to disconnect the battery pack power. Or, I read that you can also not connect the +VCC line from the J-Link (but I haven't confirmed the behavior).

There is also a GitHub link to be able to adjust the torque assist levels when using factory firmware, which will create the .hex file which you can then flash to the motor. The web page where you actually set the values is currently hosted at z8config.pages.dev and also includes the link to the programming files located at the ebikestuff.eu (otherwise the attachment is too large to upload here).
 
Howdy. Ist there any Firmware Backup Out there that works with the 860C ?
I bought a Kit with 860C from someone that tried to use osf Versions and failed (because heute got Stock 860C ) but did Not do a Backup. Now i tried the test3 Firmware but it seems to be incompatible to the Display (Motor works but i See No Speed, battery ist shown as empty while showing 49,6 volts and Motor seems to shutdown every 5 Seconds. Also ist throws random Errors 10H, 18H, ...)
When using the 860C Versions from mbrusa it does nothing but showing 1CH Error.
As i dont have any Hardware to flash the Display maybe someone can throws me a Link to a Stock Version of TSDZ8 Firmware which ist 860C compatible. (J-link i have)
(Sorry for grammar but my autocorrect ist Set on German)
