for voltages 1.8v and 1.45v usually is the voltage associated with soc

Has the pmi6125 been replaced? is the problem solved? For those who use the usual BQ model charging ic, this problem occurs short on the SMB_INT regulator

try to take it from another cellphone with the same ic code because buying a new one doesn't necessarily mean the ic is in good condition

1.it's ok 2.is thats short or no? if short you must change the output is 5 V if no 5v its mean PMI is broken cause the regulator Boot_pwr no out 5V and check VPH_PWR on inductor its same out with Vbat?

Try to check step by step using active and passive measuring avometer For active measurement using avometer LCD position must be attached - LCD VSP - LCD VSN - LCD_RESET_N - LCD_TE0 - LCD_ERR_INT_N - LCM_NTC - TDP0_LCM - TDN0_LCDM - TDP1_LCM - TDN1_LCM - TDP2_LCM - TDN2_LCM - TDP3_LCM -...

check communication between cpu and emcp

- Check USB_PMI_DP and USB _PMI_DM - Check regulator on BOOT_PWR (C1502)
