    Hey folks!
    Could you please enlighten me on how to recover my bricked Inspiron 5520.
    Currently it beeps until I power it off in a 1-1-1-... pattern (which means "Corrupted BIOS" I suppose).

    What I've tried so far:
    1. Downloaded the most recent BIOS (that is 5520A17.exe)
    2. Extracted the firmware (QCL00A17.fd)
    UPD: 2.1. Rename the firmware to QCL00X64.f? (replace the ?)
    3. Put the firmware to a USB stick (8GB FAT32 worked well for me)
    4. Plugged in the stick (tried all ports) and attached the AC power source (while holding the END key)
    5. Noticed how the USB stick blinks a few times
    6. Waited a decent amount of time.

    As you've already guessed, now I am pretty much stuck and need your help.
    Am I missing something?
    Shall I rename the firmware as I noticed some people do (to what?) or make some extra steps in addition to those mentioned already?

    UPD: Phoenix Tool suggested the filename to be QCL00X64.f? and (guess what) it worked like a charm!
    (of course I replaced the .f? with the proper extension)

    That said, I confirm this BIOS recovery method works properly for Dell Inspiron 5520.
    Thanks for reading.
    Cheers!

    And the method for Dell Latitude E6420 ?

    I put the A25 bios. Computer works partially. Can't reflash (power-off on reboot so flashing process don't start).

    I would like to try another version of the BIOS, maybe roll-back to A16.

    Thanks.

    Finally, I fixed my laptop with the help of someone on another forum. I had to buy a flash programmer wich "clamp" and dump my current bios. Then we replaced the MEI firmware by a default/non-configured one and reflash my laptop.

    Working again!

    Is there any chance that this will work on precision m4800. When I updated the bios the intel management engine firmware update is the culprit and not my PC won’t boot at all? No dell logo. It all started when I change to uefi boot.
    Hope you can help

    You are making already multiple posts for help, but have so far been denied information about your Dell Precision M4800.
    Please try to understand that the computer with this name has a lot of different configurations and different editions and they are very different from each other. For example, they definitely have different BIOS versions starting with M4800A04 and ending with M4800A26, and maybe some more that I don't know.
    Some of them only work in legacy mode, some also in UEFI mode.
    As long as nothing (absolutely nothing) is known other than the trade name, it is not possible to give any advice. The computers with the same name have been very different.
