HI,

My computer crash when i was burning the bootloader. Now the Z-Uno doesn't respond, i tried factory reset and rescue mode but nothing happen. When i plug the usb cable my computer don't recognise the chip anymore.
When i power up the chip, i have a solid green and solid red light only.

Thanks for the Help!

Please try the rescue mode. But if it does not help, it is bricked. If you don't have special apparatus to directly access flash via SPI, you have to send it us for a repair.

If you are skilled enough to use Arduino to access the flash directly, it is possible to do it yourself. One user did it in the past

This is how he did it with RaZberry. You can do pretty same with Z-Uno.

If you are not afraid in general, we can instruct you

i'm not skilled enough to write code,

i will try to exchange it
