I have this Iphone 4, with water damage.

Symptoms

1. Turns On ONLY if connected to USB.

a) Connected to laptop -- Iphone only loops the apple logo

b)Connected to wall -- Iphone turns on and display

message ´Connect to Itunes` after a few seconds, it

reboot.

After reviewing concern topics, i decided to:

1. Open Iphone

2. Clean all contacts , corrosive formations with

isopropilyc alcohol. I also removed the heat shields

for a deep clean.

3. Changed battery for a new one ( the older doesn`t

show to be expanded due the water).

Nothing worked : (

My theory is that both battery works fine (older and new one) because it shows same symptom after battery replacement. The dock connector looks good because it work when plug, but doesnt work 100% at all.

'''For the last test, i removed battery, connected to USB, and turns on, same symptoms.

''' so it´s not a battery problem....maybe a blown fuse?

Did someone knows whats going on?

Help will be really precious.

There might be a few screws that aren't exactly the right size and I've tried switching some of them to no avail. I am sure the screw for the battery connector is correct.

I am told the antenna is connected via screws?

Any help would be appreciated.

Thanks!

they both have no water damage.

tried a new dock connector and battery, still no fix.

itunes keep saying

"There is a problem with your iPhone.

we're sorry, the iphone you connected may be damaged and cannot be activated for service. we recommend you visit your nearest apple store for more information.

have read this could be the baseband chip...

any ideas?

thx

about 2-3 weeks later, i had my phone on the charger, went to sleep, and when i woke up my phone was off.

i turned it on and it worked perfectly, as soon as i unplugged it from the charger it turned off and would not power on until i plugged it back up.

when plugged into the computer, it goes into a reboot loop.

and now all of a sudden, when powered on while on the charger it does not get wifi, nor a cellular signal.

i took the phone apart. cleaned the dock connectors, and all the things suggested in the already answered questions but nothing has worked for this problem that just came out of the blue.

even now when i turn the phone on , it doesnt even know the correct date and time.

any suggestions ?

I bought a second hand iPhone 4 a few weeks back and knew straight away that the gps and wifi was crap, i also found that the speaker has blown. i had to open it up the other day to clean the camera of dust, while inside i noticed what looked like missing screws, i though no more of it it all till today.

I was trying to use a running app that couldn't track me so i thought i would look into it, while on here i spotted picture of a emp shield that has screws running through it that make up the arial, i also read that static can interfere with speakers.

here's a picture of my phone and all the missing screws, whats missing and where can i buy it guys?.

I asked the seller (who shipped before responding), and he said that it supports both.

What should I do?

I having a problem with my IPhone 4, in the beginning I was having a problem that when I wanted to turn on always saying that no battery remaining even if It was plugin, so I tried first to clean the dock connector and nothing happened. Then I tried to replace the battery with a new one and the phone saying 100% and worked for some minutes, then turn off and only worked with the wall adapter. Now I tried to change the dock connector for a new one and then tried again with the old battery and the phone never finishes booting up, then tried with the new battery and only works with the wall connector like the last time.

Now I don’t now what other thing could be...

Maybe can you give me some advice?

First off let me say, that i have changed 60/70 screens succesfully already.

Anyways, got a broken iPhone 4 32gb from one of my brothers friends, with a broken screen (cracked, could light up but displayed no image). I don't know the history if the phone. After taking it apart, it is clear that someone with no skills whatsoever has been messing with it, and the screen was not an original one. Several screw where overscrewed, the clip for the battery is missing, the speaker is semi-broken, and only 2/5 screws for the top cover is still there.

Anyways, after having installed a screen that i know works (tested in a different phone), the problem is still there. It lights up, but shows either completely white or rather obscure colors.

I was able to take a couple of screenshots with it, and after hooking it up to my computer, these show the "insert SIM" screen.

I can't activate via iTunes, but iTunes recognizes it as an iPhone.

The water-indicator is still white, so I don't think it has been in water.

Any ideas as to what might be wrong? I have checked the connection to the screen 4/5 times and tested with a different screen, same result.

Thank you so much!

Regards

I bought new display panel but pinched and broke the left hand connector off of display assembly.

I re installed old display but display was damaged in removal. I can turn phone on and off, call it but can not see any icons. Can all the phone info still be retrieved?

Or should I buy another display assembly and install???

The only issue is that now, the battery won't charge. The screen shows the cable is connected but no "lightning sign" to show that it's charging. The charging level remains at 5%.

I have restored the original setting, rebooted the phone but no result.

I have to put back my old battery.

Anyone was able to overcome this issue?

Thank you

First off, the battery % indicator doesn't seem to increase when on the charger. For example, my wife had 55% battery power when she went to sleep and put the phone on the charger. When she woke up, still 55%. She restarted the phone, which then dropped the battery level to 22% (even though it had been on the charger all night).

Now the phone is randomly restarting by going black, then immediately to the startup screen (white Apple logo). It restarts very often.

Obviously something is very wrong. Could it be that the battery we received was a lemon? I had no trouble with the installation. The phone does make and receive calls, when it's not randomly restarting.

I reinstalled the old "quick to drain" battery, and the problems stopped. The phone no longer randomly restarts, and the battery indicator level (%) does increase while being charged. It's looking like the new battery itself is the issue.

Please help! My wife can't live without her iPhone.

The touchscreen has a weird behaviour. This started after I replaced the home button on iP4. On starting the phone, I noticed that the screen doesnt have touchscreen towards the center of the screen only on both the sides (longer edges).

Currently Im not sure what the issue is fully, Im thinking maybe the digitizer cable got damaged, though Im not sure.

I also think that the front facing camera is not working. When I enable that from the lockscreen camera, I notice that the it gets stuck and flickering.

Except wifi, non other connection works : no gps, no gsm, no gps.

At the begin, I was thinking that my problem come from the missing (blue) inductor who's normally present on the bottom on the logic board (between silver and cooper connectors) and bridge it. But no change. Now I see that either bluetooth and gps signal are missing (functions work but no detection).

Is there a part (broken or misplaced after tear down) who can explain all these ?

Thanks,

Patrick.

My friend had broken mine iphone 4 completely, it had a broken front screen and back..

So he decided to repair this phone in a repair shop..

The iphone had a itunes logo with usb cable popping up after the front screen and back was repaired... before the glass was broken the iphone worked fine..

So i tried to restore the iphone but on the end of the software restoring, when it has to complete the restoring, i get a error code -1 from itunes.

I have searched for this problem on internet but there is no answer or something. The only thing i know is that the error code -1 means that the iphone needs service.. I tried new battery, new dock connector and tried to restore that way but no luck.

Does anyone had this before ?

is my iphone dead ?

Anybody know how to help, i have replaced speaker housing and dock connector so im out of ideas.

I've remounted everything!

The only piece that i haven't remount is a little piece of black rubber: its dimensions are 8mm x 2mm x 1mm.... I don't know where is the right place for it.

I'm repairing iPhones since 3 years now, but the last two iPhones showed some bright spots in the corners. They come, when I push the edges of the glass (not very powerful). This can't be normal. Is it possible, that I have any repairing mistake by attaching the Front Assembly on the frame?
