I assume you think Q1403 is short because it is getting hot? Q1403 will always get hot on short on VCC_Main. Remove Q1403, add voltage to line after Q1403 and find real issue causing the short.

Its short Vcc main ..remove q1403 and try inject voltage on red mark to find short ..after u find short then jump q14013 good luck bro

Q1403 connects vbatt to vcc_main. If q1403 getting hot it's because there is a short on vcc_main

pmu doesn't work when vcc_main is short because there is a huge voltage drop...

You don't need to remove Q1403 as long as vbatt is not shorted.
Just jump power to VCC_main and find the hottest cap without heating up Q1403
