Decryption of Kernelcache
Has anyone had any success decrypting the kernelcache of any of the 3.1.2 or 3.1 firmwares? Using the newest build of xpwntool, I still get thrown an error. Seems it may have to do with the compression of the kernelcache...

until 7a341, the last block of the DATA section was not encrypted, since 7c144, it -is- encrypted, this may cause problems in xpwntool.
