Thanks for the tip, but it doesn't work. The mce.ini is the original file as I have reflashed the phone. If I remove it, and reboot, it does show up once with the orange light, so it may be related to some software issue.

It seems that there is no engine1_mode, engine2_mode and engine3_mode under "/sys/class/i2c-adapter/i2c-2/2-0032", is that abnormal?
