Get beyond apple logo (which is only seen when plugged into charger)?
I was given a broken iphone 3g which had "stopped working" according to the previous owner.
The only thing it does to show life is to display the apple logo briefly, when plugged in, but only to the wall charger. (XP laptop doesn't recognize it, even with a fresh install of itunes.
I noticed lots of lint in the dock connector initially, which I cleaned out with a paperclip. Then I used some 90% alcohol with a toothbrush to clean out the dock connector socket.
I've tried recharging for a while, restoring via itunes (not recognized), and entering DFU mode (no luck.)
The best I've gotten was the 'connect to itunes logo' after I disassembled it to test the battery (good with 3.7v across the larger, outside contacts) and further inspect and clean the logic board and dock connector.
I'm not sure what else I can do. I'm tempted to spring for a new dock connector. Interested in the your opinions and suggestions for further troubleshooting.
I left the iphone on the wall charger for ~3 hours, and found the following link to similar problem which described how to get to DFU mode in a slightly different way than I was trying.
I'm now able to download latest update from itunes (36 mins to go) so hopefully this will work, or else I will get an error and try iRecovery. Fingers crossed
Es esta una buena pregunta?
