1 boot loop after screen replacement
Hi fixers !
i daily repair phones , most of them are iphones,
now today i had this weird issue,
costumer came for a screen replacement from a iphone 5s ,
no problemo , i connect the new screen (just to test it)
and the phone is in a boot loop it only will show the apple logo for a minute and then it turns itself off,
put the screw wrong? ---> cant because all screws all out (testing screen without annything on it)
tried new battery,
tried restore in dfu but it wont reconize in itunes because it only starts till the logo..
annyone knows what the problem is?
would be awsome!
thanks alot for reading/helping me
UPDATE***
nothing worked, new screen , new battery.
so i send the phone for motherboard repair.
Hi Brian,
A couple of questions.
- Does it do the same with the old screen? And if so, did it do it before (if there is a good way to ask the customer?)
- When you say it turns itself off, does it mean the screen just goes to sleep or does the phone actually shuts down?
