I have a YB Rio that needs an ECM upgrade due to DTC P209600.
When trying to complete the ECM upgrade event file 660 or 721, the download reaches 50% and fails with an error message 'Failed (code:5021-27-7f36)'.
Error code encountered during ECU upgrade (5021-27-7F35)
The tablet and VCI have the latest software. The error occurs in both auto and manual mode. Tried to upgrade the ECM with VCI 2 and VCI 3.
Please use it after updating sw to the latest version. The error part has been resolved.
