How to replace the U2 ic ? With hot air ?

marcin_sm1 · 11-03-2013, 12:48

as a hot air
I unfortunately did not help jumper, on the phone powers podpięciy cable, sometimes start and operate a minute, but still indicates that the battery is 100% flat to 1% and the phone goes off again. I would add that not work for me the power. I question for you, if I can turn on DFU without power button? : (
I want to load the new iso, but the computer does not detect it and the power button does not work. battery is charged via the moment and later they try to enter for iphone and charging August off, and so non-stop. I would add that the kabelku pin 3 is slightly zasniedziały and probably think only of his therefore current and therein lies the problem. cable is new and original.

Sir,

I found your posts very nice. Please help me with my problem.

I have an iPhone5 which was working good. But then one day I left it turned off (battery %age was 20-25%). I left if off for 7days and then when I tried to charge my iPhone it didn't charged.

I kept it connected for more than 10hrs but still no power.

I then decided to open and check the battery. I check the pins of the FPC Connector of the battery which connects to the motherboard with a multimeter and was showing ony 0.2- 0.6volts (all 4 terminals, 2 at a time). I cracked open the battery and the charge on battery pin (not on FPC connector was 3.2v) I then charged it by soldering wire on it and charge was near 4v.

But I put it back on iPhone it still does not power On.

Please tell me what possibly could be the issue. Still the connector pin of battery is showing 0.2v -0.6v

Pleaseeeeeeee
