I have a Dell Inspiron 15R-5537 notebook and Dell has recently released a BIOS update for it, version A09. This update has some important fixes. Current BIOS version is A08. This update is for Dell Inspiron 14R-5437, 15-3537 and Inspiron 14-3437 models too. As you may know, Dell BIOS updates are .exe packages which can be installed in Windows or through a bootable DOS USB drive.
I tried to install it in Windows but the flasher says this message: "NOTICE!! Running on an unsupported system". Nothing happens (it's supposed to reboot and flash the new BIOS firmware) and the only option is cancelling the procedure. I was able to flash the new firmware from version A06 to current (A08) without a problem, so this is the first time this is happening.
Dell states that you can also flash new BIOS firmware via DOS, and so I did. I installed FreeDOS (1.1) into a 4 GB USB drive (formated in FAT32) with two different applications:
1) using Rufus 2.2 (FAT32, MBR/BIOS etc.)
2) UNetbootin (Diskimage option) + 1.1 FreeDOS .img file. I choose Option 4, "Load FreeDOS without drivers".
And then I moved the update file (5437A09.exe) into the root folder of the USB driver.
As I have Windows installed in UEFI Mode, I enabled Legacy Boot and disabled Secure Boo. Then I choose to boot with USB drive, and then FreeDOS starts. I enter "5437A09.exe" and then a message shows up asking me whether me to start the procedure with [Y/N], so I type "y".
Unfortunately, nothing happens, and it gets stuck, even after very long. Then I have to enter Ctrl + Alt + Del to reboot the notebook, and I was lucky it didn't brick it, probably because it didn't actually start the flashing procedure.
So, I woud like to ask you if there's something else I could try, because this BIOS update has some really important fixes. I don't believe I'm doing anything wrong, I really have no idea why it's not flashing the new BIOS firmware, either in Windows or in FreeDOS. Thanks in advance.
