How to do it?
It's very important for me, please help
I assume your Power Button not working or Any other Scenario,Soldering Power Button doesn't digest properly to me,but yeah 2nd method is good enough,but you need computer to do so.
But even then you are not satisfy than here's a simplest method to boot your device without Pressing Power Button,i know it Because i've been pass through this situation.
I assume Your Phone is switched off Or ran out of battery but doesn't boot automatically like it suppose to do so.
Method: Take Out Battery Cover,Plug your device into Charge,Shake lil bit gently,Next thing you'll notice it will vibrate means it's Powered ON,Now put back Battery Cover,you don't need to Press Power Button Anymore.
Simply Follow Steps....Everytime you feel so.
