Flashing with SDKManager - completeSetup failed

Hello,
I tried to flash with the most recent version of sdk.
i followed the instructions, set recovery mode, sdk detected the device, downloaded everything, build image and failed when flashing it
In the logs i can only find:

error: completeSetup failed. Error:
error: install process failure

what can i do?

Your log says you don’t put the board into recovery mode at all. Please make sure you are using J512 type C port.
Only this port can do the flash.
