The front LED no longer works on my E02's. They used to work fine but I'm not sure when they stopped working. My pink E02 has 2016.05 U-Boot, and a black E02 has 2016.09.
I think they stopped working after a recent update. I have the following in my U-Boot env:
$this->bbcode_second_pass_code('', '
arcNumber=3542
machid=dd6
')
I also have 2 V4 mobiles using 2016.05 U-Boot and the LEDs are working fine on those.
Any ideas where to look to troubleshoot?
