Back up data and do a factory reset and keep your fingers crossed

can you back up??

[dvickyiest]

seem your download is corrupted. take it to samsung service centre.

wasee is right, you should try factory data reset.

take it to service centre and update the phone by System

Plz restart the phone in safe mode and delete the files which are corrupted, restart again

Your firmware might have been corrupted.Try factory reset for once,If it doesn't work then either you can take the phone to nearest service center(Belive me,they fix firmware problems immediately,you will get your phone back in an hour) or you can use odin, get latest firmware from sammobile and flash it to your phone to get it working again.
ps:- There's a small chance of bricking your phone if you flash incorrectly.
Hope this helps :)
