Computer won't detect OtterX

Awhile ago I wanted to change the ROM on my 1st gen Kindle, and get OtterX. Following the instructions given here, I made it all the way up to where you must push gapps and CM10, but my Kindle was never detected on my computer. I installed the Kindle Fire Utility 0.9.9 drivers and everything, but no computer I tried using would see the device as online.

I left it for a few months and now coming back to it, I unfortunately tinkered with it too much to figure out what the issue was. I activated the EMMC corruption fix because honestly I figured it couldn't be any worse then where it was now, but it didn't resolve anything. Now I can't boot into TWRP from OtterX menu, when I click that it sends me to fastboot mode. I'd push recovery and a ROM if my computer would be able to detect it but it unfortunately doesn't. I did some research and figured out how to disable driver signatures on my Windows 10 and managed to run install_drivers.bat and have that working, but now my computer is detecting my Kindle as Android ADB Interface with the yellow triangle under it. It's also listed under Android Phone.

I'd really appreciate any help I can get since being an idiot didn't help me out with this.

Root Note 3 with Android v 5.0 without a computer?

I need to know if it's possible to root my T-Mobile Note 3 Root Note 3 (N900TUVUFOB6) with Android 5.0 without using a computer. I would obviously want to put some form of custom recovery on it. Any help would be much appreciated.

Disconnects from computer after entering bootloader

I have not received the OTA update to Marshmallow yet and getting impatient so I'm attempting to sideload the update myself. I've installed the SDK and drivers. The device is listed when I use 'adb devices' at the command prompt and it allows me to boot into the bootloader. But from there it disconnects from my computer and I'm not able to push the update to the device. I get "error: device '(null)' not found". Any advice?
