Samsung Galaxy Note N7000 stuck on booting screen

My Samsung Galaxy Note N7000 on Android 4.1.2 seems to have somehow managed to brick itself. I was using it for WiFi tethering via USB to my laptop. All was good until I unplugged it. It started restarting itself but never fully starting, so I was guessing maybe the battery was messing up. Anyways, I've come to the conclusion that it's bricked. It starts up, displays its model, and reboots before it even reaches the Samsung logo. The phone has its original firmware and has never been rooted or anything. It starts up but boot loops after displaying its model. I tried accessing the recovery menu by pressing home + volume up + power but it doesn't work. I also tried vol up + vol down + power but that doesn't work either. I'm kind of losing hope because I'm pretty certain it's hard-bricked. Somehow the OS must have gotten corrupted. It charges normally and I can turn it on but it boot loops. I tried connecting it to my laptop today via USB and it's not connecting properly, the phone just charges and doesn't connect. I really need to go on my phone because I have an important number on there.
