Can your help me,about hikpack repack firmware

[aclicetom]

Hello, I want to customize my firmware package, and then I found a tool hikpack tool by @montecrypto, which is a very nice tool. I can with (-t k41) to correctly extract and decrypt my firmware package. Repack, once again upgrade no problem.
When I modified the start.sh file, then (encrypt start.sh-> md5 start.sh-> decrypt new_10.bin-> mod new_10.bin-> encrypt new_10.bin-> mkcramfs-> decrypt new_20.bin -> md5 cramfs.img-> encrypt) .After this process is repackaged, the upgrade is successful but the system fails after reboot.
I would like to know, if I changed the start.sh file, except to update new_10.bin file,is there anything else I should be modifying?how to , thank you.

but the system fails after reboot.

What errors did the serial console show on startup?
Is this a CN NVR you are trying the firmware on?

new_20.bin

I'm not sure if hikpack correctly handles new_20.bin and the small tail after the end of it.
Maybe try handling the full tail on digicap.dav manually - tail original digicap,dav, decrypt new_20.bin + extra bytes, modify, encrypt, append to new digicap.dav and see if that works.

I replaced logo.jpg of sys_app.tar.lzma, and then repack (md5sum -> ...), no problem with the upgrade, the system starts normally, my logo picture can also be displayed.
But I used the same method to modify the start.sh, like add a line "echo hello", and repacked, after the upgrade, the system failed to start. I can not connect to the serial port, I will try your method, there may be other checks here I do not know.

Was your finished new_20.bin 480 bytes long, or 476?

*edit*
Just had a thought - did you 'chmod +x start.sh' ?
Perhaps it has been left as not executable.

start.sh will run automatic,I can't control
my new_20.bin 360 bytes long.....

But before you do the mkfs.cramfs check if start.sh is executable.
If you modified it, it may have lost the 'x' attribute. The chmod +x command will put it back.
