Hello everyone, I managed to jailbreak! I used a method similar to a Vietnamese video I linked in a post I thought I had previously made here, but that post still needs to be approved by a moderator I think, probably because it's a video link and I'm a new user.
If you see a post from me asking if anyone had seen a video with a YouTube link in it after this one, that's the video I'm talking about.
But basically I didn't have to follow the "setup" section much at all all I did was:
1-Factory reset with English(UK) language
2-type ;enter_demo and hit return
3-type ;demo and hit return (I didn't even need to reboot between these steps)
4-tap "sideload content"
Then I followed the "jailbreak" and "post jailbreak" sections after, no secret gesture, no skipping wifi, no dummy values for store registration or anything. I believe I've jailbroken the kindle successfully and I can see the dummy kindle feedback book in the home page(Is there any other way to check if a jailbreak is active btw?).
After doing this I applied the K5 JailBreak Hotfix as it's explained
here, now I'm trying to install KUAL and use the renameotabin extension as is explained
here.
Is there anything else I need to do after? I can freely turn on wifi, link my amazon account and do factory resets if I please?
