When doing the Firmware Update for Unified 5D Mark II 2011Dec22 on a 5DM2 with 2.1.1, the screen goes black, the card access blinks twice, the sensor is cleaned, some random Canon Menu screen blinks twice and the card boots up in Canon firmware without giving the confirmation screen that the instructions say should be seen. The camera works normally and the FW level is 2.1.1-ml. The attached shows the files on the card.
Any help is appreciated. TIA
