I followed the APIM recovery guide referenced earlier and flashed the available strategy and calibration file for my apim module. It seems to go through the process successfully, but then ends with the message "Programming was successful, but something went wrong. Module seems to be “bricked” 
"

When I turn the car on, it seems the APIM is completely off. I no longer see the backlight and there’s no audio coming through.
Searching for the error message in this forum, I came across this post that seems to follow the same pattern as my case. Both starting to flash from 2.2.16280 and running into the same issue: similar post
To me, this seems there might be something wrong with eMMC. Any other ideas?
UPDATE: Oops, rookie mistake. I panicked after seeing the bricked message and forgot to follow through with flashing the ecu configuration for sound and illumination. I’m back to the blank screen with backlight now after flashing those. Still no display
