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
Is this a good question?
