Aeotec z stick gen7 firmware update failed

trying to update my z wave controller’s firmware from 7.20.x to 7.21.4 as specified in 700 series Controller Firmware Updates (Linux) · kpine/zwave-js-server-docker Wiki · GitHub.

tried firmware otw from z.wave js ui… it failed.
entering in bootloader mode and retrying is stuck at 0%

next move is to try the terminal flash utility?

:warning: Be sure to stop any other Z-Wave JS applications prior to running the above. Otherwise, the update can fail and the controller will be hung at the bootloader.”

the question is… what should I need to stop prior to perform the terminal flashing procedure?

Have you any further suggestion?

Any help really appreciated…

Stop the Z-Wave JS UI add-on.

do I need to install wget in order to flash the firmmware from the rpi terminal?

terminal wins…flawless victory!
