Received board for solutions and it was dead found short on VBAT line using DCPS gave 2V to short line and CPU was heating, unsolder CPU with 330C of heat and short was gone.
This is first time when i see that CPU uses VBAT voltage which is equivalent of VCC_MAIN in apple devices.

What pads on the cpu does vbat go to ?. Are you sure short wasnt on another line which linked cpu to vbat and taking cpu off broke the link, but other line is still short ?.

Possible i was wrong and something else was short because i took PMU off and there was corrosion and i tested there is no link with VBAT to CPU but anyway i have the CPU can solder it back will have a good experience.

I have burned my finger can't do much waiting to cure.
