Wont Turn on

[manjubuddy]

Hi,

I was on call and phone got switched off automatically even though there was 20-23% of battery.

Phone is not turned on later, i charged mobile for 3-4 hours and followed instructions suggested in the below link

but phone is not detected in system at all.

Please suggest

Connect your phone to a wall charger > press and hold power & volume up at the same time for 10 seconds > let it charge for 2 to 3 hours > then repair your phone with either PCC or SUS

Hi,

Thank you so much. It is working fine.

But phone is too slow 

Spoiler

[Uliwooly]

Slow in what sense?

[manjubuddy]

Touch was not responding properly.

It worked fine for 2-3 hours.

Now again it is not booting up.

When i press power button, Vibration is coming. but mobile is not booted up at all.

I tried removing battery and all. Problem still persists.

is there any permanent solution or do i need to change mobile?
