I have to say for those who recommends to turn off, on, or let battery drain, then charge and restart or restore are lucky because the chip didn't shorted out. The problem is you are using some metal tool when you disconnecting the LCD connector, you must use plastic spudger or similar to remove it. Sometimes, when you are removing the glass after powering off, the power switch could be triggered and powered on while removing the glass, then you touch the connector with metal, that's when it shorts out. Better way to prevent from this happening is to lift the board from the battery which then assures 100% shortage of chip won't happen.
