Hello Forum

I'm working with BQ25720 for charging and BQ4050 for Lithium Ion with 2S chemistry. I accidentally connected the battery in reverse polarity and after that BMS was not working. I was unable to connect to BQ studio. Then I found out that the discharging MOSFET was not working and i changed it along with BQ4050. Even after that I'm unable to connect to BQ Studio. Below is the schematic of BMS.
