iPhone turns off as soon as I put the back cover on.

I have solved this, it is the rear camera. Check your installation. Confirm by pressing around the digitizer flex with the phone on. If it turns off, you know where the problem is. I'm not exactly sure what causes it but I just fiddled with the camera seating and that fixed it.

i have the same issue. no idea what to do here?

Tried different backs.

Different batteries

Removed grounding clip up by the Flex cables.

Removed grounding clip next to battery.

Checked battery terminal solder points

No idea what to do here.

Some help me! lol.

Hi there,

I've just solved such a problem on my iPhone 4. The key worked for me was to stick a transparent tape on the whole back of the back cover, but the little connector.This is being done so it prevents from closing any electrical circuits or so. This worked immediately for me.

It got me though crazy for a while ...

I hope this will help you.

Btw, it is a great forum!

Well wanna know what I did? Cut out a zip lock bag to cover the insides from the back and BAM !@#$%^&*!@@@! She works ;)

Hi.

Are you sure that the batteryconnector one the motherboard intact

Look if the soldering is okay:

Let me now :)

Water damage is a whole nother game play. Could be anything. Try putting it (the entire device) into a glass of 99% isopropyl (alcohol)

Anything less will conduct electricity and short circuit the device.

That's all I know to do that actually cleans and prevents corrosion. But what damage is done already, is done. Bag of rice only helps draw moisture out. Not prevent corrosion.

Try to do what I posted before about the electrical tape and let me know how it goes!

I had the same frustrating problem a few weeks ago. After a few hours of fiddling with the back cover and trying some software resets to no avail, I rechecked that all of the various flex connectors were securely in place and swapped the back out with one on another phone and it worked fine. I'm not sure what fixed it, but I have a hunch that the the standoff screw that the battery connector screws into might have been too lose so that the battery connector didn't fit all the way into place (leaving the connector high enough off of its socket to be affected by the back cover).

After reading this forum and the solutions you guys came up with, I went and tried something a lot simpler on my phone which is exhibiting the same problems. I found that pushing down around the camera caused it to turn off...and sliding the back cover on would be pushing this camera hardware down towards the bottom of the phone...so I got a tiny piece of paper, folded it up so it could fit right under the camera lens and prevent it from moving, and bam! problem is solved. Cover went on a bit more snugly than usual, but it works like it's supposed to now. Saved a lot of time for someone like me who doesn't quite wish to take a stroll down "take the whole phone apart" road.

I done what Pavel ^^ did and put some strips of tape on the inside of the cover and it worked straight away. Suppose I could have tried the tape in sections to see where about the contact was causing the problem but it had wound me up too much that the fix was that simple I just left it.

Some people mentioned the black tape on the screw under the camera but thats for the iphone 4s.

Thanks I had same problem drove me nuts I also btok a piece of white tape ontop of back cover it now works fine thanks:)

I had this problem as well and just put a piece of clear tape on the WHOLE inside back cover. Worked like a charm!
