Hi,
It seems that after selecting ALEOS firmware, you select Radio firmware immediately, so the ALEOS firmware is not uploaded to device, only Radio fw is uploaded. It causes the mismatch between ALEOS and Radio Firmware, so you can not access ACE manager anymore.
From your picture 1, your device is in Recovery mode
Please follow this document to recover device.
