This is the 2nd Kindle Fire 6.3.1 I've rooted. The first one works like a dream thanks to everyone here at xda, you guys also helped me root and overclock my s3. My friend asked me to do his kindle and I'm having problems I searched through the forums to no avail. I already had the driver installed and checked my device manager on windows 7 and saw that everything was working . I opened up ADB 0.9.6 saw that I was online and rooted it, everything went fine. When I tried to boot into recovery nothing happens well almost. When the kindle fire logo is up it flickers and I think I'm seeing the recovery screen but it's only for a fraction of a second. I can't get the triangle to pop up. I also don't have the SU in my app drawer. I have tried everything I can think of. Any ideas?
