[Q] Will not boot, flickers quickly
Hello. My wife recently dropped her S2, with enough force to eject the battery. It had worked after she put it back in and all, and even called me to tell me about it. However, the battery ended up dying before she plugged in it. When plugging the phone into usb, the button lights would flicker and the battery charging icon would flash on for about a second. Rinse and repeat. If there is no battery in the phone, it just flickers the buttons, and the screen will flicker back, and just do it over and over.
The USB port on it was already really shoddy, so I bought a new ribbon and replaced it. Same symptoms. Pretty sure this is a hardware problem, although what the problem is exactly I do not know. I've already reseated all of the ribbon connections I could find. There's obvious signs of previous water damage, but it looks like very old damage. I wouldnt' be surprised if something is corroded, but the timing of this happening after it was dropped makes me think something else came loose. I just don't know what. I could potentially try to reflow the motherboard with my heat gun, but before I waste my time doing that, I was wondering if there's _anything_ else that could be causing these symptoms.
