Chosen Solution
I dropped my 3G a few months ago but it kept working. Lately, it started behaving weird: the screen would fade to white and then the phone would restart. I found out I could prevent this by pressing the screen (like a cardiac massage) while it was fading to white. Yesterday I opened it carefully, sprayed the inside with canned air, replaced the 1, 2 and 3 cables and put it back together. It seemed to work perfectly, yay! Today, less than 24 hours later, it suddenly died. Completely. I opened it again, disconnected and reconnected the 123 cables again, but to no avail. It is totally dead. I tried USB and wall power, nothing. It just won’t turn on. Does anybody know what went wrong? Thank you. UPDATE: Guys, I’m officially getting scared. The phone is hot. Not like, on fire…but it’s not cold. Did I unleash a demon?
I disconnected and re-connected cables 1, 2 and 3 very carefully and it came back to life! Thanks, problem solved.
