My girlfriend and I found a nexus 5 completely abandoned. No battery power left and the charging port was VISIBLY messed up.
Repair was easy and worked perfectly. Downside was we found out the LCD was also broken.The cause being from water damage. But now it charges and can turn on. Just can't unlock the screen.
Sometimes you need to be a little rough. When taking out the broken part I was afraid of messing things up so i was a little gentle and it took me a little longer then I would have liked. Get mean but ALWAYS know what you are doing.
