How can I get the variable s and data?

k = s - sha1sum(data)

P.S.: His explanation: the vulnerability is that p is 0, which makes r=1, which makes s = sha1sum(data) - k

Your recovery must update the signatures on the Codegroup Descriptor Table (CDT). If it does not, your recovery will brick the phone if you attempt to flash a custom ROM.
