Kernel 2255 has a blocklist for certain .xex files.
Updates since 4532 will blow an eFuse and increase the lockdown counter in flash by 1 (robinsod).
Public Releases use a simple folder structure
xbox-ht.dl.msecn.net/content/xenon/7357/0/0/system.manifest
xbox-ht.dl.msecn.net/content/xenon/7357/0/0/FFFE07DF00000001.cab
xbox-ht.dl.msecn.net/content/xenon/7357/0/0/FFFE07DF00000002.cab ect...
Beta builds use a hashing structure that would take a few days to brute force per file. As with typical Microsoft content servers the characters in the hash are HEX, thus you have a limited range of [0-9][A-F] but that is 16^32 possibilities per file. The system.manifest file has 16^16 possiblities, but would not disclose the hash of the other files (possibly if decrypted).
