When to use Kindle Serial Number?

If you have an E-Ink Kindle device, like Kindle Touch, Kindle Paperwhite, etc., and the books you want to decrypt are directly transferred from the E-Ink Kindle device, then you can use the Kindle's Serial Number for removing DRM.

Notice: If your books are synced via Kindle for PC/Mac, do NOT input any Kindle Serial Number or PID for removing DRM, which would cause the failure.
