MRPI isn't used and isn't needed on a K2 (or K3 and K4 either). Custom bin installer on that device are all installed by simply copying bin file into "root" of Kindle removable drive and then after ejecting from computer and using "Update Your Kindle" option.

You don't need KUAL to install new, updated DevCert/MKK. Just copy "Update-mkk-20250419-k2i-B003_keystore-install.bin" and install it using "Update Your Kindle" UI option.

If KUAL doesn't even show in your list of book then you used wrong file or copied in into wrong folder.
(you new to use "KDK 1.0" azw2 KUAL file and place in into "documents").
