Help Signature Verification Failure When Rooting Question

[SunMad30]

Hi All,
I was reading on this issue and just out of curiosity. Does the method you use to fix this problem depend on the phone and variant you have or are their general fixes? Thanks in advance for your answers.

Not quite sure what you mean. Are you flashing a zip?
Which device?
Which Android Version?
Which Root method???

Signature verification during rooting is usually related to trying to install a (typically) signed .zip file in stock or custom recovery.

A stock custom recovery requires that the .zip (file being flashed) be signed with the manufacturer's signing keys...failure to do so typically indicates a .zip file that was NOT signed thusly.

A signature verification failure from a flashing operation during a custom recovery either means that signature checking was turned on and the "jarsigner -v" type of check on the .zip file failed or that you have an incomplete (i.e., corrupt) download (would explain the signature verification failure if the signature is based off of an incomplete file).
