Why won't my iPhone boot after replacing the GPS antenna?

Hi guys,

I have a problem with my iPhone, after replacing the GPS antenna (it was broken), the iPhone won't boot. When I switch on the iPhone the Apple Logo is shortly flashing on the screen, nothing else!

I tried a recovery without any signals on iTunes!

Any tips or ideas?

Sorry for my "english"!

Greetings from Germany

Answer this question I have this problem too

Is this a good question?

Now i tried a restore on my XP Notebook, unfortunately, with the same result.

Oddly enough the device reacts only if the cable USB is connected.

When i press the power button for a longer time, the Apple Logo flashes every 3 seconds.

I am absolutely helpless!

Greetings from the USA!

Try putting the phone in DFU mode and then doing a restore.

Unfortunatly there is no way to back up your phone right now so you will have to use a previous backup.

1. Connect the iPhone to your computer with the USB cable. Make sure iTunes is open.

2. Hold the Home and Power buttons for 10 seconds.

3. After 10 seconds release only the Power button and continue to hold the Home button until the phone shows up in iTunes.

4. Proceed with a restore and your phone should be OK.

The reason the phone may not be working is a conflict in drives/firmware of the new GPS/Antenna.

Hope this helps!

I had a similar problem with an iPhone 3G I worked on- is there any water damage in the dock connector? If there is, that will prevent it from connecting to the computer.

Sorry to get back to you so late. I try to answer as many questions as i know i can help with. If the phone has a spinning apple logo then something went wrong when you put it into DFU mode. Do you have Windows or Mac? Try restoring you iphone on another computer. This may just be a software issue.

That's certainly a nice thing... water damage is very annoying, not to mention nigh impossible to fix. How slow/fast is the blinking?

if you press the Power button the Apple Logo is visible for 0.5 seconds.

I think the device cant boot while they have a not visible failure.

Yesterday I have measured the battery, since the device can be switched on only with cable inside, the voltage is 4.0 V.
