PW Can't open Kual, item not signed by an authorised developer.

haadi71 · 05-22-2025, 12:18 PM

Basically the title. I uninstalled the older kual which was not opening because i no longer had the permissions so i hold it and delete the item just like a books. I then transfered the kual.azw2 file to the document folder. And now the it is giving me the error that the item is not signed by an authorised developer.

Known issue. For more information see this post.
Depending on your jailbreak and model, the DevCerts can be copied to the root folder or need to be copied to the mrpackages folder and installed via ;log mrpi
If you don't get the Hush, little baby... message after searching for ;log mrpi you might have to reactivate the ;log command. (This might not work for newer Kindles, but it worked on my ancient PW2.)

For me it took several reboots, but it eventually worked.
I don't know whether it makes any difference but I tried other known semicolon commands, e.g. ;411 before I entered ;log mrpi again.

But that developer keystore zip doesn't contain the bin for PW i.e kindle paperwhite 1

AFAIK, Update_mkk-20250419-k5-ALL_keystore-install.bin should work for a PW1.
(It worked for my PW2.)

I'm still having this issue and done multiple reboots following installing DevCerts (K5 ALL) in root.

I installed jailbreak kindle-jailbreak-1.16.N-r19426

DevCerts appear to install with Update kindle

But launching KUAL-KDK-2.0.azw2 tells me it's not signed.

I have run emergency.sh and now have the .done and other two files. However, ;log mrpi does not show me the Hush, little baby... and the cert file remains in mrpackages

Here's my 411 info, does any of that help?
