Help Galaxy S4 Completely Dead! Please help

[richs128]

Hi all.
So basically I cracked my lcd the other day and i replaced it myself.
All was fine for about a day and then my phone went completely dead.

I thought it may have been the charging port so ive ordered a new one of those

Waiting for it to arrive.

I've tried a new battery (fully charged) and a new charger.
I do not get any lights at all completely dead.

Anybody know of anything else that could be stopping it from powering up?

Many thanks to all!

Try taking the battery out for a couple of minutes, then press the power+home key for 10 seconds or so.
Then replace the battery and do the same again.
whilst doing so after the battery was replaced, did you feel the device vibrate? If so, then at least then you know it is receiving power from the battery.
If not, then either a connection was loosened during your screen installation, and its disconnected, or the device is hard bricked.

Hi thanks for the speedy reply!

Ive opened it back up since and checked all the connections, also the mother board looks good.
Ive tried every power up combination under the sun! and none seem to work, ive also tried the way that you said to no prevail either.

I think it is hard bricked like you said (I just found out what that means). How do you unbrick it?

Thanks for the help

How do you unbrick it?

Unbricking requires a motherboard replacement unfortunately.
