I have same issue. Mine was chocolate wine though. Lol Everything works, just speaker for ear very low. I've disassembled and liquid sensor/sticker still white(in middle of iphone4) but there are several red dots on the earpiece speaker. Are those also liquid detection stickers or are they supposed to be red? I've looked at logic board and ribbons and detect no signs of liquid exposure(no dried wine that I can see or sticky parts). What should be my next step? I have it disassembled still.
I have the same issue. Really upsets me. I thought it was due to my reassembly but now I'm convinced it's a flip of the coin on if the phone accepts the battery. My battery was dying like crazy. And I finally went and purchased a new one from eBay. Same APN as original. 616-0435. One wouldn't charge. Put Back original. It did.... But original won't hold charge. So I ordered a replacement. This one would also not charge. Put back original. Now I ordered a 3rd 616-0435 and this one charges! Success so I thought... But now I started getting random reboots. Now I ordered another APN:616-0431 or 0432... This one charges and works great. BUT it won't update firmware. I get an error 29. Very frustrating. So I'm stuck using this battery on 4.0... I can not upgrade to 4.2 So !$^@%#. Anyone can offer s solution to this issue?
