BIOS recovery

Question

I have been trying to do BIOS recovery on dell Inspiron 14 5480 following the content below.

https://www.dell.com/support/kbdoc/en-th/000132453/how-to-recover-the-bios-on-a-dell-computer-or-tablet

however it doesn’t work. Here is my status.

1. I push ctrl+esc then plug-in. The screen is black with 3, 3 flash light on plug-in light (I google it, it means I don’t have recovery file)

2. I download and rename BIOS_IMG.rcv and place it in usb, but it still doesn’t work, black screen with 3,3 flashing light

3. I also tried this link, but the command line in the link doesn’t work for me (C:\\ /writehdrfile /writeromfile)

https://www.dell.com/support/kbdoc/en-th/000130691/bios-recovery-steps-for-a-no-post-issue-on-alienware-aurora-r5-r6-r7-r8-r9-r11-and-xps-8910-8920-8930-pcs

Now I wonder if I could download BIOS recovery from dell website for Inspiron 14 5000 or contact dell support is the only option for me since the first link doesn’t mention Inspiron

Please help, thanks.

========================
My pc is dell inspiron 14 5000 (5480) mfg year 2019 with OEM window 10

Additional info, I tried to format and reinstall window to reallocate disks space and partitions, but I messed up and delete everything (including recovery data for factory reset, I think). I somehow manage to install window with recovery window download to usb but couldn’t boot it (no bootable device found problem). I tried to fix it in BIOS setting and here I am.

Please help me. Thanks

If you are experiencing problems with your Dell computer's BIOS, such as a failed or interrupted BIOS update, a corrupted BIOS, or boot issues, you can attempt to recover or restore the BIOS using the following methods:

BIOS Recovery from Hard Drive: Some Dell computers have a built-in BIOS recovery feature that allows you to restore the BIOS from a special partition on the hard drive. To access this feature, you usually need to press a specific key combination during the boot process (such as Ctrl + Esc or Fn + Esc). Consult your Dell computer's documentation or visit the Dell support website for instructions specific to your model.
BIOS Recovery from USB: If your Dell computer does not have a built-in BIOS recovery feature, you can create a bootable USB drive with the BIOS firmware and use it to recover the BIOS. Dell provides BIOS recovery tools and instructions on their support website. You will typically need to download the appropriate BIOS firmware for your model, create a bootable USB drive using a tool like Rufus or Dell's BIOS update utility, and then boot your computer from the USB drive to initiate the recovery process.
Contact Dell Support: If you are unable to recover the BIOS using the above methods or encounter any difficulties, it's recommended to contact Dell's technical support for further assistance. They can provide specific guidance and support based on your computer model and the nature of the BIOS issue you are facing.

It's worth noting that performing a BIOS recovery is a sensitive procedure, and if not done correctly, it can potentially cause further issues or even permanently damage your computer. Therefore, it's essential to carefully follow the instructions provided by Dell or seek professional assistance if you are unsure.

The problems solved

I consult IT service shop. Hard reset solved the problem, the bios is good and don’t need recovery.

“No bootable device found” is also solved. The problem is probably from recovery window I download from dell is not complete due to poor internet connection. The shop use window downloaded from Microsoft and it work just fine.
