Re-Flash a Corrupted Dell Inspiron Laptop BIOS

There is absolutely no guarantee that the following method will work for you, as reading this sentence you agree that I take no responsibility of any kinds of any damage caused by the following this procedure.

This is how to recover from a disastrous BIOS update...
Simply follow this procedure to re-flash failed BIOS update on a Dell Inspiron (N5010 model in my case) laptop. Presumably the following method also works on almost all other Dell models.

Phase 1
First of all you have to download the correct firmware from Dell Official Website:[ http://downloads.dell.com/bios/N5010A15.EXE or Download N5010A15.EXE ]
Use Windows Command Prompt (run as administrator) to extract the required firmware files.

  • C:\>cd /Downloads
  • C:\>N5010A15.EXE /writehdrfile
  • C:\>N5010A15.EXE /writeromfile

Rename the newly created N5010A15.HDR and N5010A15.ROM files to N5010.HDR and N5010.ROM.
Format an USB thumb-drive to FAT and copy the N5010.HDR, N5010.ROM files on it. You do not need to create bootable USB drive.
*UPDATE: most of the time I hear feedback about this method people add a comment that they formatted their USB thumb-drive to FAT16 as the FAT32 file system did NOT work.

Phase 2
Shutdown your faulty laptop if is is still running with the black screen.
Remove the battery
Remove the CMOS battery
Disconnect the power supply.
Insert the USB drive in the USB port. *UPDATE: According to the feedback on this method most people use the left USB socket, as the rest of the USB sockets might not functioning at this state.
*Note: There are few cases reported about not active USB ports. Simply try to use other USB port if you notice or suspect that the system cannot read the USB drive from the port you plugged it. Use USB drive with activity LED if you have one, the blinking LED will confirm that the system reads data from your USB drive.

Phase 3
Press and keep hold the END key on the keyboard for your faulty laptop.
Plug the DC power connectors (power plug) into the laptop.
After a few seconds your faulty laptop will start itself and will re-flash its corrupted BIOS and automatically reboot.
You can release the END key after the flashing process started. A USB drive with an activity LED can confirm that the BIOS flashing process started. The complete re-flashing process will take no longer than 60 maximum 90 seconds.
