I went to recovery mode and clicked 'apply update from .zip file' and opened that downloaded file. Then i rebooted my phone again. Since then, whenever i turn on my phone it keeps flashing Samsung continuously and doesn't start.
If you can't repair it and its in good physical condition but useless I'll buy it for parts to fix my s6 edge.
