[Q] Can't find my device's firmware to update it, pls welp.

I can't find the firmware for my device (Galaxy Tred Lite Duos), my cellphone broke and the screen is just black, even when I turn it on. I've been looking everywhere on the internet for my device's firmware, but I don't seem to be able to find at all, even here.
Here's the exact problem:
I turn on the phone. The booting animation doesn't appear. and the screen just lights up a lil' bit and nothing happens. Im pretty sure it's not a problem with my screen. But I think that just a firmware update can fix this. welp.
How do I fix this?
(Again, my device is a Galaxy Trend Lite Duos, GT-S7392L is my firmware.)

S6 Edge Struck in Grey Screen

I have a Sprint S6 edge and i was not using it as i upgraded to Priv.
Recently, i want to use it and when i switch on the mobile , it just Grey screen with Lines in once off and simple grey screen in other off. The device is getting ON , going to download mode etc. However even after flashing a new firmware the device is still struck in the same screen. Basically i feel that the display is gone. But as the display is getting switched on , can it be any software issue ?
Have any one faced this issue before ? .. Can you please guide me what needs to be done here ?
