I upated ten Xenons to the latest FW (v0.8.0-rc.26) yesterday. Nine went well and one got bricked.
After flashing it lit up briefly and then got dark. None of the on board LEDs light up if I power it up or press one of the buttons.
I own a J-Link and have Segger Studio installed. I still can read the memory using Segger Studio / J-Link. It looks like the bootloader is corrupt.
What is the correct procedure to bring it back to life?
I found the bootloader files here https://github.com/particle-iot/firmware/releases.
To what address do I have to burn the bootloader? 0xF4000?
Thanks in advance
