Defective Black Jaguars?

[kamocat]

From the information you've provided, it sounds like the Jaguars in suspect work, but just don't support CAN.

Are ALL your black Jaguars like this?

Could you update their firmware again, and see if that changes anything?

We had an issue like that on 2 different black jags. We just flashed the firmware again and they worked fine

I know this is old, but I want to post my (odd) results.
When we re-flashed them, they worked fine, and I forgot about this for a while, until I flashed one again, and it did not work. After some testing I discovered this pattern:
Flash -> works
Re-Flash -> does not work
Re-Flash -> works
Re-Flash -> does not work
Re-Flash -> works
Re-Flash -> does not work
Re-Flash -> works
Re-Flash -> does not work
etc...

It appears that re-flashing a working Jaguar will fail, causing that Jaguar to not work. Maybe something to do with the bootloader.

If this pattern is the case for all jaguars, I would think that the manufacturer would want to know about this since it seems like a resolvable issue (even if the solution is just to release a notice to users about the existence of this phenomenon).
