Iphone 4 continuous reboot – bundle of problems ! old iphone set please help

On January 23, 2015, Posted by , In iPhone, With Comments Off on Iphone 4 continuous reboot – bundle of problems ! old iphone set please help

Hi friends,
I want to be helped. My iphone 4 not power on.
The behavior of iphone is the same both Along with and Along without battery.
When I connect it to pc Along with usb cable the logo of apple appears at the center of the display and then after 2-3 seconds it restarts continuously.
If i dont connect usb cable and connect only battery it give me no signs of life.
I check carefully (like marked by tesla in one of his picture) the continuity of battery connector and test points, and it is all ok.
What can it be? title=confused and what do you advise me to do? Thank you.

    could be a problem related only to the battery? how can I know if I have to purchase a new one? because the connector is ok ..

    Ive got a motherboard that does exactly like yours, i know its caused by the battery: if battery charge is below 5%, iphone will not boot (It will reboot) the problem might be that your battery is not getting charged, or that its ruined.

    Id test FL5 and FL7 for continuity (Read the schematics) and if theyre ok id change the battery.

    Test the iphone Along without battery also, it should do exactly the same.

    I had a similar problem after I replaced a missing battery connector. Turns out there was a faulty connection and it was fine after I resoldered it.
