gl-mifi Modifying led causes MODEM to be unable to connect

I compiled the firmware of lede17.01

I used the openwrt configuration backup file

I found led not bright

When I modify the LED configuration through Luci, I find that MODEM is no longer working

This is the configuration file I have back up on openwrt and restarted

MODEM works and LED is still not working

Have anyone come across this problem

Not too much info for investigation, as this is your own firmware, we don’t know what you have done.
