Im trying to repair my own phone because of the housing is damaged and the screen too. While im tearing down my phone i forgot to remove the battery cable and accidentally hold my power button so for a few minutes my phone is on while im tearing down every part to move it to new housing. I realized it after seeing my home button has a white led so i quickly remove the batter cable. But after i moved it to new housing my phone wont turn on anymore.
Any suggestion what should i do ?
