Help Light Flow causes display to turn off

[nwh10]

Help! I've caused a terrible problem. I have an LG Optimus Fuel L34C, which is rooted. I installed Light Flow, and it was working except it wasn't sending any signals to the LED. In an effort to get the LED working, I put Light Flow in test mode, where it asks the user to turn off the screen within five seconds. The LED remained dark and the display remained dark.

When I try to turn on the screen by pressing the power button briefly, it displays for a split second and then turns off. I have tried pulling the battery and turning the phone back on. The display only shows for a split second and then goes black. How can I disable Light Flow when I can't get the screen to stay on?

**Edit**
I've pulled the battery again, and the display now remains on when I turn on the phone. I've disabled Light Flow and will start over trying to get it configured.

I'm glad to be beyond the black screen problem.

I had a similar problem on my GNex. Turns out LightFlow was recognizing my screen as an LED and was trying to control it. I just had to disable it in the app. I had to email the dev for help, but he was both prompt and friendly.

Yes, Andrew is really helpful.

After I got beyond the original problem, I found that LED didn't operate when LightFlow was enabled. Andrew directed me to phone settings/display, LED to make sure that "notifications" was enabled. I did that, and found that there is an additional setting that needs to be enabled. It is Settings/Display/Home button LED/Front LED – Downloaded apps (use LED notification with downloaded apps).

All good now.
