    Re: need bios dump dell latitude 5420 (cpu 11th)

    My programmer cannot identify the BIOS ic.
    It is:
    XMC
    25RH256CXIQ

    I'm using ch341A, EZP2019+, and RT809F Programmers. All softwares are up to date. I need to unlock this Dell 5420 11th Gen Laptop

    Thanks in advance

        Hello friends I got Dell 5420 11th gen with password so I have compared almost all unlocked files with hex editor on this thread to see how I can unlock mine but it seems there is differences because I thought the password is stored in the same offset so was wondering if I am missing something. I am not well vested with bios editing of the new bios. I have attached my locked file if anyone can help unlock and also give tips on how to do it.Thanks
