Between lv0/updater and lv1

After proper cleanup it'll be put here

Structure (from first hash until signature)

Size Description
0x14 Hash of Section
0x0C Padding?
0x10 Key?
0x10 Iv?

This repeats until signature which has the following structure...

Structure (signature)

Size Description
0x15 R(Starts with 00, when xored in same position returns 00 due to crypto fail)
0x15 S(Starts with 00)
Remaining Padding?
  • Note: If the hashes of a section match (which usually happens with the data section between small revision changes) you'll see 00 in the xor
