I can't find the correct scatter file for my LG G3 Stylus

Hey guys, i need a little help, so i was messing with custom roms, and i probably corrupted the bootloader but my PC still detects my Phone as "Mediatek USB Port", so maybe there is still a chance but that port disconnects every 2 seconds, like when i connect my phone i see it in device manager and it disconnects again, i've tried all of my USB Cable, and btw the phone is all black screen, can anyone help me? and i don't have a scatter file for it even if i get the drivers to work, help me.
