Installed TWRP, phone forever on boot animation. Need data from device

Hey, I haven't rooted my phone in years, and thought I'd try it to goof around with some stuff. When thinking of backing it up, I thought I had everything off of it that I cared about, only to realize afterwards that I don't have my recent videos of my child backed up.

1. I allowed for unlocking in dev options
2. Boot into fastboot mode
3. Flashed recovery TWRP 3.0.2 bullhead
4. Boot into recovery

TWRP asked me for my pattern to unlock my phone. I gave it the correct pattern, and it keeps saying that it's wrong and can't unencrypt. I gave up on flashing superSU since I couldn't boot, and now my phone won't boot.

I've tried flashing an older TWRP on (2.8.7.2) to try to get things back up and running, but no. Any help would be appreciated!

If I unlock my bootloader, do I loose my warranty forever?

So, if I unlock my bootloader and my phone gets bricked and needs service, will I be able to use my warranty? If not, is there a way I can make the phone look like it has not been modified in any way(ex: maybe lock the bootloader again or something like that) so that I can use my warranty?


Thanks in advance.

Note taking forever to recharge

For example today it took over three hours to charge from 57% to 100%.Phone was being charged whilst turned off.

Noticed the other day when recharging both the recharger & the back of the Note got pretty warm whilst recharging & phone turned off.

Could this be caused by an app, say something like anti-virus, I run Avast?
