for context i dropped my s5 on the upper right corner on pavement. The screen was actually smashed before but it worked, since it only shattered the surface but not the real screen. Now after this drop the phones screen is black/wont turn on. You know you get a different shade of black when the screen works but no, it doesn't do that, its dead. Im looking to replace the screen but the real question is: when i turn on the phone step 1. screen wont work. step2. the blue indicator light goes on and then dissapears(like on a normal boot.). step 3. the phone vibrates 3 times and then repeats the vibration a few times. step 4. when i plug the with usb to my pc, it says galaxys5 but no files found aka i think the phone doesn't boot properly. i have really important files on my phone and i dont want to lose them. since i think it boots faultyly(? english?) im not sure if replacing the screen works. Is it a motherboard malfunction and can the motherboard be replaced without data wipe ? I'd really be glad if anyone knows about this
