iPhone 6 stucked in apple logo after replacing u2 ic

Hi. A customer brought to our store an iphone 6 dead after plugging in car charger. I replaaced the u2 ic and it started charging with the correct voltages but it just stucked at logo and wont go further. I see no short and the mainboard doesnt heat. It didnt fall to water. The voltage going into battery is between 3-4.xx help pls. The client doesnt want to lose his inforrmation.

I did it maany times now. Same result. The voltage is ok tho in the baterry conector from the board. If the u2 is placed incorrectlly it will just dont charge or the voltage in that conector should be less that 1v

I would first repeat the chip replacement since this can occur after a bad Tristar chip replacement.

There are many other things that can be wrong. One of them simply being the data is corrupted and you need to update or restore (and loose data). Can you connect to ITunes?

That's good to know. @rany I got a 5S boot looping and flashing red screen. Definitely water damaged. But I'll be glad to try the u2ic before anything else

You'll need to disconnect front cam, fit a known good battery, make sure gas gauge is attached, replace Tristar, and restore from DFU.
