So what happened is that my mobile (Galaxy S4 - GT-9500) ran out of charge.
When I plugged in the charger and tried to turn it on, it went directly to what I think is the recovery mode (Android logo with text "Downloading...Don't turn off target")
I turned it off, pulled off the battery and tried to turn it on again nothing happens.
I tried different solution but nothing happens, just the black screen Here is what I tried so far:
1- Home + on/off button + volume up
2- Home + on/off button + volume down
3- plug it in the PC for hours and then along press on the on/off button
Any other suggestions ?
