Samsung Galaxy Note II (SGH-T889) suddenly stuck in reboot loop, please help

A few weeks ago I installed Resurrection Remix on my Samsung Galaxy Note 2 (SGH-T889) following the instructions of this site:
teamandroid[dot]com/2016/03/08/update-tmobile-galaxy-note-2-t889-android-601-resurrection-remix-marshmallow-custom-rom/2/

Everything worked great for two weeks, my phone had better battery life, had the new OS, even played Pokemon Go (which it wasn't supposed to be able to do). However, yesterday it crashed when I was surfing Chrome on IGN's mobile website, and ever since has been stuck in boot loop. It boots up, optimizes # of # apps, and reboots. I can't stop it.

The thing is, since it's this way, I'm not sure how to get it back to flash it or anything. The recovery mode seems like it's back to the Odin crap again instead of the CWM recovery mode, and I can't download/install stuff on it in the current state, etc.

It's an old phone so I suppose I could go get a new one but meh. I love my Note 2. Never had a problem till now. Any ideas? Thanks!

Help with possibly bricked SGH-T889 Samsung Galaxy Note 2

Long story short, I haven't done any of this stuff for a long time.
I did stuff here: .teamandroid.com/2016/03/08/update-tmobile-galaxy-note-2-t889-android-601-resurrection-remix-marshmallow-custom-rom/2/
I followed the instructions but I think where my hiccup happened was for whatever reason, CWM didn't install it's custom recovery system even though it said it had. So I'm stuck at 3e restore. However, in my stupidity and haste, I already wiped the data because I thought I was already in the CWM menu and didn't realize the 3e system would look so similar to the screen shots. Now I can't install the custom roms because they're not signatured, and I can't install a way to bypass the signature because that stuff is also not signatured. The only access I currently have to my phone is now through an ADB Sideload functionality using my PC.

Trying to at least get back to square one, or is there a way I can flash the CWM recovery system from this location?

Thanks for any help, not sure how to proceed from here (phone has no OS on it)

SGH-T889 turned into a 7100, can this be fixed?

So I was running 4.4.4 (I forget who's build) and I just did a search on marshmallow and I saw a CM 13 so I flashed it without reading. I know, stupid noob. Anyways, my phone now says it is a GT-N7105 on android 6.0.1.

I do not like it. Before I try, I was curious if anyone knows if flashing it back is possible.

Thanks
