I have a jailbroken PW2 9017 with 5.4.5 (downgraded it to JB then updated to 5.4.5).
I followed these install instructions:

Everything went seemingly smoothly (no error messages or anything), but there is no Duokan anywhere in sight. Kindle continues behaving as it did before, booting to the Kindle OS. I installed the Duokan launcher from this thread, but using it does nothing.
Anyone knows what could be happening?
