[Q] Help me, can't get into download mode

My nephew's galaxy note was stuck at the boot screen. It was never rooted or anything, just stock. I couldn't get in recovery, only DOWNLOAD mode. I was just messing a bit a around with it and flashed the n7000_16gb custom pit file through odin. It didn't do anything , so after like 15 minutes I just pulled the usb out. Now it won't even boot into download mode (JIG). I also installed the latest samsung drivers through KIES.

Can you help me please , I don't know what to do anymore.....
