My problem is, if I create a fullbackup I don't have the ULK info available anymore...The ULK definition is one of the rules imposed by @The_Ripper and @Telesat to easily recognize the kernel version inside file patch.e2 container and being able to manage it from their AZUp Tool !!!
For a more professional control ... for example ... you could discriminate (FNIB) magic header that on unlicensed kernel version (vmlinux_xload.zbf) start always from offset address x00000090h ... while ... on the licensed version (xrpc_xload_vmlinux_ES4_prod.bin) at this offset address begins data area for Hash customer key definitions (Sigma SDK) for SoC's XRPC control & decrypt kernel on VRAM
so I need a way to find it out just having the kernel.img or of the running system
Can you give me some more details to the more professional control?
