Stuck on blue logo!
I'm having a similar problem... I recently got a second hand Kindle 2nd Generation already rooted with Cyanogenmod 10.1.3.otter2 on it. Google Play and some other apps where having issues, so I decided to downgrade. After testing a couple of different ROMs, I got stuck on the blue logo, an infinite booting screen. Funny enough, I think the mistake was to install a Fire first generation ROM into a 2nd generation. Anyway, long story short, I've tried everything, Kindle First Aide (won't help because it seems that all the options need me to be in the desktop of the tablet and I can't get there), SDK ADB will see the device but return a device offline... I'm running out of options and don't really know what to do!
Any ideas guys??
