iphone 6, intensity loop no boot

[angelo50]

Hi guys
I do have an iphone 6 plus for which I change the 2 touch ic components
Since that, for an unanderstood reason, it does not boot anymore
If i plug it to my 3.7v power suppply, i can see that the power supply react when i press the power button, the amps goes up and down without and and no reaction on the phone
If i plug it to itunes, nothing happend until I force the dfu mode but then, it goes to 4005 error
Thats weird
I spent 10 hours to try to understand but I'm stuck
I have changed U2 but still the same
Of coure, I removed the two touch IC to check if I created a short but no...
If someone has an idea...
Thanks

Yes, I thought about it because of 4005 error but this would cause the ampere looping ?

Hello..
maybe you have worked with to high temperature and now you have a short under the CPU or other parts on the other side. But first remove the both Touch ICs . (The phone is able to start without the ICs ...) Maybe they defekt or shorted
good luck!
