    No need. I understand what you are talking about without illustrating examples.
    It means that you can't get rid of the whitelist. If you're disappointed, don't buy HP notebooks next time.
    If you need 4G right now, I can check the whitelist of your BIOS for any allowed 4G module.

    I actually need this 4G using this HP lt4211 Gobi 4G Module. That means I need the BIOS without whitelist. That's it. Please. I really don't want to buy another HP 4G module. :(

    Sorry, can't help you. HP devices are the most secure.

    This is different. People devices were made before HP took such serious measures to protect their firmware soft.
