How can I fix my bricked device?

[Android Central Question]

My Samsung Galaxy Note 10.1 (GT-N8010) has been bricked somehow after flashing an incorrect zip file using the Samsung Normal recovery (Not TWRP or CWM). I have lots of precious apps and data on there that I have not backed up. I can only seem to be able to access Download Mode at the moment and nothing else (not even the recovery using the Power + Volume Up keys). Right now my tablet is switched off but for a whole night, it was stuck on the boot screen until it stopped. Can somebody please help me access my device again? Thanks in advance.
