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!
