I changed my phone theme.
His phone was off.
I turn now, again came off the field and on the field again.
What was I right?

I don't understand the issue, could you elaborate?

Repair the phone with PC Companion.

Hi, 

I am having the same issue. My phone has been randomly turning itself off for a couple of days now. However, this time it has turned off and I can not get it back on. 

I have tried to connect it to the PC companion but it is not recognising the phone as being connected.

Any advice would be appreciated?

@TheFort

could you try different computers, usb ports and usb cables

So, yesterday my phone worked perfectly. Before it discharged.

Phone won't turn on, led quickly turns on and off when plugged into pc(charger isnt the problem, cause it makes hissing when plugged which is normal atleast for me. )

Battery is fine, even tried with another battery from a x8(the connectors didnt get damaged from it,phone noticed it but still doesnt boot up.)

PC or anything can't recognize the phone.(checked with adb devices)

As i said charger is fine and also tried other chargers.

I booted up with luck into recovery 2 times, didn't show battery percentage and also random times.

I don't think that any of the stuff installed(rom recovery and root since i own this phone for 3 years) made a problem this big.
