Error Retrieving Box. Message: E: footer is wrong E: signature verification failed

[Luiz Claudio]

I've been with Box bricked for some time. I have tried several roms but none works, however in every attempt when installing a new rom the message "E: footer is wrong E: signature verification failed" appears.
Can anybody help me?. How do I get this signature check when installing a new rom ?. It looks like there's a script for this. I do not believe that to solve the problem I have to spend several hours trying different roms.

Thanks for the help.

You need to sign the zip with the same key that the recovery accepts.
2 options remain, either you have the key and sign the zip or your flash another recovery that accepts other keys or no key

Dear Abdul, I have little experience with this kind of problem. Could you take a step by step? Thank you.
