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

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.

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