home button doesnt work (have assistive touch option activated) so this is not a major. But now when he tries to charge it, it comes up with the 'plug into itunes' picture. When he does, it says it needs to be updated or recovered. He tries to update it, and it says, it cant be, and it needs to be recovered. He tried this, then did the updates.

But the prolem is recurring. I have found instructions on many fixes on this online BUT I am wondering if any of these fixes are pointless, because the problem originated from water damage, and so may be more of a hardware problem than software. THANK YOU.

I've taken the back off and measured the battery with a multimeter and it measures 0V but I suppose that's not surprising as the phone hasn't been used since it stopped working over a year ago.

With the charger connected I measured the left and right pins of the battery connector in the actual phone and it measured 1.15V, not enough to charge the battery.

My guess is the dock connector is ok or I wouldn't see 1.15V. Does that sound right?

If my guess is true then perhaps it's the logic board that's at fault.

I've measured continuity through L3 and L4 but have not worked out how to get access to L28 to test it.

How am I doing so far, does the above sound right?

Thanks for reading

After having it professionally repaired, it's somewhat working.

• Boots normally when connected to wall power.
• Shows Apple logo for 10 seconds, then turns off, when connected to computer for power/sync.
• Battery does not work; must be connected to wall power.
• Wifi, Bluetooth, Cell Network do not work due to water damage.

So, I'm having a very hard time finding a way to get my data off this phone. It must be connected to the wall for power, and thus I can't connect it to my computer.

One solution I can imagine is connecting the phone to wall power *and* connecting it to the computer at the same time.

Do any adapters exist that would enable this?

EDIT:

I've just now tried charging via my Apple Cinema Display at work.

When my Macbook is not connected via Thunderbolt, the iPhone charges fine off the display's USB ports (as if it were connected directly to wall power).

However, as soon as I connect my laptop to the display, the iPhone shuts off.

There must be a short in a syncing-specific area, unrelated to power?

I don't know what to do. Can't figure out a way to get the data off this phone.

facts:

The battery lasts longer now, but seems to drain faster now.

I have opened it up, alcoholed with a q-tip what I could and I feel dried it out well. I noticed no corrosion inside as I had to wait for the kit to open it for about a week.

It seems to take longer to charge.

The water sensor in the headphone jack is still white.

I think the water sensor in the docking port is gone--I see no red or white.

It connects to my computer fine and I backed up the phone.

There seems to be a lot of lint in the docking port.

What can I clean/replace to get me back to good at this point?

Are there other water sensors inside that I should look at?

This site is great!

Some days ago I lost my iphone somewhere at my work place but the good thing was I took backup of everything just a day before the incident to my PC (Windows 7) via iTunes. Now I have purchased a new Android phone but as all my data has lost I am unable to restore it to my Android phone.

Please help me with this.

I want to restore the iTunes backup installed in my pc to my Android phone. How can I do it?

Kindly help me out with this.

In this second phone, there was NO battery ground clip as there was in the first re-install. Obviously someone else has been inside this phone before.

My questions are:

1. I am sure this ground clip is important, but how so?

2. I would be happy to open the phone back up and install one....but where do I get one?

But it does not hold a better charge with the new battery. I put the back light on low, shut off all apps I am not using, have manual data retrieval on, turn off wifi when I'm not using it, etc. All the battery tricks of the trade.

Is this because of IOS 7? Or is there a different problem with my phone? Is there a certain charging pattern I should follow? (Let it die completely then charge? Charge at 50%, etc?)

Is this actually necessary? The battery doesn't seem to physically obstruct anything with the camera replacement. Perhaps it is necessary to cut power to the phone components?

Thanks,

Steve

It seems the battery only charges when plugged in and powered OFF! If it is on and plugged in, the battery will drain but at a slower pace.

Do you think I damaged my battery? or shotty reassembly that could have caused this problem? I was thinking I would try and replace the battery as a first step of trouble shooting.

Thanks in advance for any help

Is it essential? and how and where do i put it back?

In the tutorials I can see it positioned between the outer shell and the dock connector cable, but nowhere is mentioned that it can come loose, or how to put it back or how to attach it

secondly; is it possible that because of that missing part my screen is litting up dim.
