iPhone 7 Stuck On Apple LOGO

Hi Guys.. Hi @refectio SIR

I have an iphone 7 (NOT water Damage). When i connect it to DCPS, show 0,22 0,23 amp, and stuck on these values. 

There is only apple logo on the screen.

Dont restart, just stuck on apple logo.

Check Audio IC, but no improve.

The phone doesn't HOT, there is no short on the board.

I found only long screw damage near the battery, unfortuanlly i did'nt find nothing on ZXW about LSD on phone 7.

If i try to reset have error 9.

Is there any suggestion  plz?
