Kernel cache decompression fails on some iPhone versions

Hello,

I have tried to extract the iOS kernel cache from iPhone 6,1, iPhone 6,2, iPhone 7,1 and iPhone 7.2. The kernel cache appears to be decrypted correctly, but the result of the decryption is not a lzss compressed file. I have this problem for iOS versions 7.1.2, 8.4.5 and 9.3.5.

I have extracting the kernel cache from the iOS versions above on other iPhone (and iPad) versions, and they work just fine.
