[Q] Huawei G6- U00 problems with the notifications led

[PODLi]

Hi,
I have Android 4.4.2
The led on my phone used to blink whenever I got a message in Whatsapp, Line, missed calls and whatever.
After I rooted the phone it stopped working. I can play with the led through the 'brightness' file, in /Sys/ Class/ leds folder, but no application can trigger it. It lights only when I put the phone to charge.
I tried various led apps, that claim they can assist with the led, to no avail.
Can I config something in the aforementioned folder? Does anybody know how I can play with the 'trigger' file there? Is it a matter of security?
I looked over the Internet already, but there wasn't any constructive/ detailed help about messing with these files.

Cheers

Did you tried to return back to stock rom (without root), so you can confirm that it work for you?

Hi,
I didn't try to un-root.
I thought I could find some help to solve the problem.
Un-rooting is not an option for me.

So I eventually flashed the rom again and I got the notification led working again, but now I can't manage to root my phone
