[Kindle Fire Q&A, Help & Troubleshooting] Adraemond:
Alright, last night I attempted to do all of the neccesary steps to install SlimKat ROM onto my Kindle Fire 1st generation on 6.3.3 and eventually got the Kindle to have no OS installed, wouldn't boot into recovery (would just power off), and ADB would not respond (device unauthorized). The only thing that worked was fastboot commands. At the moment, that Kindle Fire is on the back burner. I now have a second Kindle Fire and am attempting the same thing but have recorded all of my steps and am stuck.

From my understanding, if a OS was installed ADB would be asking for permission. However, since one isn't I can't grant permission and the device is stuck in offline mode. What do I do?
