In our device we are using the BQ27520 fuel gauge. When I've tried to update it with bq27520G4_3_29 firmware in GaugeStudio I got firmware update error and now the fuel gauge looks absolutely dead. There is no answers on I2C bus, and BAT_LOW signal always 0 despite of battery state. Are there any possibility to get this gauge working or we need to replace it?
Thank you in advance.
