Does manually flashing the phone reset the data/app on it?

Can you please tell me the complete procedure? After unlocking bootloader what to do? In SDK Platform if I run these commands then will there be any problem like functionality issues or anything? It would be very helpful. Thanks

It worked but during the process, while flashing system and vendor file I got Invalid sparse file format at header magic
Is it normal? The phone is working fine but checking whether it's normal or anything else needs to be done?
It would be very helpful. Thanks
