[Q] Can't copy ROM after installing otterX topic

I followed Hashcode's guide to install the OtterX partition scheme and updated TWRP to 2.8.2.0, and did it successfully, But now I can't figure out how to copy a ROM to the device, I've already tried to use the USB mount(nothing happens) Already tried adb push(unauthorized device) Already tried adb sideload(closes). I am at a loss of what I'm supposed to do, I have already installed the Kindle Fire usb drivers, and my device is found in adb, but it says it's unauthorized, I have no way of booting into a ROM, is there anything I can do?

[Q] How to switch from Otter to Otterx topic

I have Rooted, Pacman 4.4.4 RC2, TWRP 2.8.02, FFF, Amazon Otter installed on my "Original" Kindle. Can someone help me with steps to take to switch to OTTERX? When I read through the directions in the OP, it is written for switching from Stock. Thanks for any help. Also, would switching to Otterx show much benefit?
