There are two different API BS2_ResetConfig & BS2_FactoryReset.

1. BS2_ResetConfig : Deletes all configurations

- If the 'include DB' is true, zone-related tables(except user and event log) will be deleted. 

2. BS2_FactoryReset : Deletes all DB & configurations

- It deletes user and event logs too.

- Device operates this API to protect information when secure tamper occurs(SSL)

- We have an issue that it doesn't clear all configurations including background image due to unconsidered conditions. 

In conclusion, please call both BS2_ResetConfig(including DB=true) and BS2_FactoryReset to initialize all configurations & database in the device.
