HCM module bricked after update

Hi everyone, I was trying to update the HCM unit in my car due to AFS motors not communicating. The original FW version was 7S71-14C084-AE, and I attempted to flash the newer 7S71-14C084-AK version.
​The programming started, but after erasing the blocks and during the writing process, the procedure was interrupted. Now the module is bricked. How should I proceed to recover the module? Any advice would be greatly appreciated. Thanks!"

Did you read the section on recovery mode?
