Iphone 4s powering only with cable and keeps restarting.. help! - GSM-Forum

trami · 07-19-2014, 22:50

Bit of history - It had water damage and was fixed in a lab for power problems.
Still had heating issues after it was fixed.
Wi-fi stoped working twice and i reflowed to make it work again.
Now it just wont turn on, only with power cable, and keeps rebooting on apple logo.
Tried changing battery - didnt work. Tried reflowing the whole mother board - didnt work. Tried changing power dock - didnt work.
Anyone got a clue on this one? really desperate...

Does show only Apple logo ?

Yes shows apple logo for 10 seconds then rebooting, then shows the logo again and so on.
It isnt a software issue, not battery, also changed charging dock with no help, gotta be something electrical if anybody knows..

Your problem should be in the area near of battery connector. Check nearby carefully with a microscope if there are any damaged components..

Hi, having same issue but mine don't seems water damaged ,don't know the history of the phone it was in 2 shops before .No missing things after microscope inspection .
I found the dock connector faulty (the flex broken a little).
I will concentrate in the J3 area.
Wites ,any idea ? if you read us, regards guys.
