Accessories resign KUAL-KDK-2.0.azw2 fix issue"The title is not signed by a registered developer"

[zzhzihui]

Hi all, my devide KPW1 jailbreaked,to fix issue "The title is not signed by a registered developer" when you open KUAL-KDK-2.0.azw2.
I resign the KUAL-KDK-2.0.azw2 file with new 'developer .keystore',is works fine on my KPW1,test on KPW1 5.3.3 ok,when update to 5.6.1.1 is ok too.

if not jailbreak do the follow: (thanks for chaitanyaI )
- Simply put, download "kindle-jailbreak-1.16.N-r19426.tar.xz" > extract kindle-5.4-jailbreak.zip > extract and put all files into root folder of kindle.
- Come to settings > update you will see ***JAIL BREAK***
- Now what I done is, copy the latest 'Update_mkk-20250419-k5-ALL_keystore-install.bin' for K5 from DevCerts-20250419-KeyStore.zip, placed in root folder
- again, settings > update
now KPW1 is jailbreaked,and update the mkk new keystore

the magic step:
- now donwload the 'KUAL-v2.7.37-20250419-azw2 resign by zzh.zip',extract KUAL-KDK-2.0.azw2 and place in kindle's documents folder,open it in kindle,it run well
KUAL-v2.7.37-20250419-azw2 resign by zzh.zip

you can aslo install Update_KUALBooklet_v2.7.37_install.bin ,this version is runok.(thanks shamanNS )

then you can install MRPI ,and other extensions.
