Dev certificates on Kindle touch 4th gen

Spirou1 · 09-29-2025, 12:06 AM

Hello everyone, this is my first post here so I'm sorry if this is not the correct place to post. Anyways, I have a Kindle touch 4th gen currently on firmware: Kindle 5.3.7.3, a few months ago I did a jailbreak process in it and basically just forgot about it, until a few days ago I exited Kual and started getting an error saying:

"The permissions to open this item have expired. Please contact the developer"

I did some basic research and found out that this has to do with the dev certificates, but I'm having some trouble understanding how I can fix this issue. If anyone could help with this, it'd be greatly appreciated. Thanks!

Hi there, i have the same problem for my Kindle 4NT.
The fix should be here, however for me it doesn't work.

I am running on the 1.0 KUAL .azw2 file.

Any findings are appreciated.
